Description

COMPRESSOR FOR PRODUCING ENERGY EFFICIENT COMPRESSION

EFFECT

FIELD OF THE DISCLOSURE

[0001 ] The present disclosure generally relates to compressors, and, more particularly, relates to a compressor capable of producing an energy efficient compression effect.

BACKGROUND OF THE DISCLOSURE

[0002] Compressors are devices or machines that are employed to increase pressure of a compressible fluid. The term 'compressible fluid' as mentioned herein may refer to any compressible fluid, either gas or vapour. The inlet pressure of the compressible fluid may be of any value from a deep vacuum to a high positive pressure. The discharge pressure, i.e. the pressure to which the compressible fluid is required to be raised, may range from sub atmospheric levels to high values in tens of thousands of pounds per square inch.

[0003] The compressors may be of 2 broad types, positive displacement compressors and centrifugal compressors. The positive displacement type compressors are either reciprocating type compressors or rotary type compressors. These compressors work on the principle of compressing a volume of the compressible fluid to produce the desired pressure change. On the other hand, the centrifugal type compressors work on the principle of increasing velocity of the compressible fluid to produce the desired pressure change.

[0004] The applications of compressors are innumerable. The compressors may be used as pumps for fluid transport. Further, the compressors may also be employed in pneumatic applications. However, the most common use of the compressors may be in refrigeration and cooling equipments, such as room Air Conditioners (ACs), car ACs, refrigerators and refrigeration and cooling plants. In regions, like India, that have tropical climates, such equipments are in huge demand. Cold storages and artificially conditioned environments are always in huge demand. [0005] However, with the increasing numbers of such equipments employed in both homes and industries, there has been a corresponding increase in the overall energy consumed by such equipments. It will be obvious to the persons skilled in the art that in any thermodynamically closed system, any energy input into the system that is being maintained at a set temperature requires a corresponding increase in the energy removal rate. The increase in the energy removal rate requires an increase in energy consumption. Accordingly, reducing the overall energy consumed by these equipments is highly desirable, especially considering the present day scenario where the energy supplies globally are dwindling.

[0006] Various solutions have been devised to reduce the energy consumption of such equipments. One such solution includes improving the overall efficiency of the compressor. It will be apparent to a person skilled in the art that the compressors form core of the thermodynamic closed systems of these equipments. Therefore, reducing the overall energy consumption of the compressors may correspondingly reduce the energy consumption of such equipments.

[0007] In addition to above mentioned disadvantages, another disadvantage that is frequently observed in these equipments is their overall size. It will be understood that with an increased demand of such cooling or refrigerating

r

equipments, the problem of storing them has accentuated. The problem intensifies when these equipments are required to be installed in households, commercial and industrial spaces already grappling with shortages of space. Therefore, any reduction in the sizing of these equipments is also highly desirable. Compressors are usually at the heart of such equipments. Therefore, to reduce the size of these equipments, a reduction in size of the compressors employed in these equipments is highly desirable.

[0008] Accordingly, there is a need of devising a compressor, which is capable of producing an energy efficient compression effect. Further, there is a need of a compressor that consumes very less energy, thereby making such compressors a green solution towards energy problems. Furthermore, there is a need of having a compressor that is energy efficient, and is equally effective in addressing the cooling and refrigerating needs of equipments. Moreover, there is a need of a compressor that is compact and light weight, thereby solving the problems of shortage of storage spaces. Last but not the least, there is a need of a compressor that is low on maintenance, and may be able to operate at very high ambient temperatures.

[00038] The use of the terms "first", "second", or "third" do not denote any preferential limitation to any element, but rather denote a distinction of one element from the second element.

[00039] The present disclosure provides a compressor capable of producing an energy efficient compression effect. The compressor of the present disclosure will be described in details with reference to FIGS. 1-5. [00040] As depicted in FIG. 1 , a compressor 1 000 includes a driving unit 100, a transmission unit 500 operatively coupled to the driving unit 100 and an operating unit 700 operatively coupled to the transmission unit 500.

[00041] The driving unit 100 may include a driven shaft 10. The driving unit 100 may be capable of being connected to an external power source (not shown) for driving the driven shaft 10.

[00042] In an embodiment of the present disclosure, the driving unit 100 may include a motor comprising a stator-rotor assembly 20. The stator-rotor assembly 20 may include a stator 22, and a rotor 24 operatively coupled to the stator 22. The stator 22 may be capable of being connected to the external power supply, which in this case is an electrical power source, for driving the rotor 24. It should be apparent to a person skilled in the art that the stator 22, when connected to the electrical power source, may act as a field magnet. This conversion of the stator 22 into a field magnet may drive the rotor 24.

[00043] The rotor 24 may include a rotor shaft 1 7 in operational communication with the rotor 24. The rotor shaft 17 may further be operably coupled to the driven shaft 10. Accordingly, the rotation of the rotor 24 may rotate the rotor shaft 17, which in turn may drive the driven shaft 10.

[00044] In another embodiment of the present disclosure, the driving unit 100 may be a belt and pulley system 200 (as shown in FIG. 3). Such belt and pulley system 200 may be similar to those existing in automobile engines for supplying driving means to compressors installed for conditioning cabin air of automobiles. The belt and pulley system 200 may be in operational communication with the driven shaft 10 for driving the driven shaft 10. In this embodiment, the external power source may be an automobile engine from which the belt over the pulley system 200 drives the power to drive the driven shaft 10.

[00045] In construction, the driven shaft 10 may include a first end portion 1 1 and a free end portion 12 distal to the first end portion 1 1. The first end portion 1 1 is operably coupled to the driving unit 100. In one embodiment, the first end portion 1 1 is operably coupled to the rotor shaft 17. In another embodiment, the first end portion 1 1 is operably coupled to the belt over a pulley system 200. [00046] The free end portion 12 may include a plurality of teeth 14 configured thereon as depicted in FIGS. 2-5. The plurality of teeth 14 configures a gear on the free end portion 12 of the driven shaft 10. The driven shaft 10 may be composed of metallic materials, or alloys, or any other material which makes it suitable for operation. In an embodiment, the driven shaft 1 0 may include about 10 to about 15 teeth. In an embodiment, the driven shaft 10 may include about 13 teeth in number.

[00047] The transmission unit 500 is provided to regulate the motion of the driven shaft 10. This regulation of the motion of the driven shaft 10 allows the driven shaft 10 to be operated by a low rating external power source, thereby reducing the overall energy consumption of the compressor 1000. The transmission unit 500 will now be described in detail.

[00048] As shown in FIGS. 2, 3, 4, 5A and 5 B, the transmission unit 500 includes a gear assembly 410 abuttingly coupled to the driven shaft 10. The transmission unit 500 regulates the motion of the driven shaft 10 via this gear assembly 410.

[00049] In one embodiment, the gear assembly 410 may include a master gear 420 in operational communication with the free end portion 12 of the driven shaft 10. More specifically, the gear assembly 410 may include the master gear 420 operatively coupled to the plurality of teeth 14 configured at the free end portion 12 of the driven shaft 10. The operable coupling between the master gear 420 and the free end portion 12 of the driven shaft 10 allows a controlled transmission of the motion of the driven shaft 10 to the gear assem b ly 410.

[00050] In another embodiment, the gear assembly 4 1 0 may include a plurality of transmission gears 430 (only one transmission gear 430 is shown in FIG. 5 A and 2 transmission gears 430 are shown in FIG. 5B) arranged between the free end portion 12 of the driven shaft 10 and the master gear 420. More specifically, the free end portion 12 of the driven shaft 10 may be abuttingly coupled to at least one of the transmission gears 430. Even more specifically, the plurality of teeth 14 on the free end portion 12 may be abuttingly coupled to the at least one of the transmission gears 430. Further, at least one of the transmission gears 430 may be abuttingly coupled to the master gear 420. The operational communication between the free end portion 12 of the driven shaft 10, transmission gears 430 and the master gear 420 allows a controlled transmission of the motion of the driven shaft 10 to the gear assembly 410.

[0005 1 ] It should be clearly noted that though in FIGS. 2-5 only a single transmission gear 430 and a single master gear 420 are shown to be a part of the gear assembly 410; such restriction should not be any way construed as a limitation to the present disclosure. In an embodiment, the gear assembly 410 may include any number of gears. In another embodiment, the gear assembly 410 may include 14 gears (12 transmission gears and one master gear). In another embodiment of the present disclosure, the gear assembly 410 may include 7 gears (5 transmission gears and one master gear). In yet another embodiment, the gear assembly 410 may include 4 gears (2 transmission gears and one master gear).

[00052] Further, the construction of the transmission gears 430 and the master gear 420 may vary based on sizing of the compressor 1000. In one embodiment, the master gear 420 may include about 80 teeth to about 90 teeth, and may have an outer diameter of about 75 millimetres (mm) to about 90 millimetres (mm), and a bore size of about 25 millimetres to about 40 millimetres. Further, the master gear 420 and the transmission gears 430 may be composed of metallic materials, or alloys, or any other suitable materials.

[00053] As discussed before, the operating unit 700 is coupled to the transmission unit 500. The operating unit 700 is the operational hub of the compressor 1000. In other words, it is that part of the compressor 1000 where the compression of an operating medium (compressible fluid) may occur. It will be apparent to a person skilled in the art that the term "operating medium" as mentioned herein may include a gas or a vapour.

[00054] The operating unit 700 may include an operating shaft 610, and an operating section 620 operatively coupled to the operating shaft 610. In an embodiment of the present disclosure, the operating shaft 610 may be a crankshaft 610 (refer FIG. 4). The crankshaft 610 may have a diameter in range of 25 millimetres and 50 millimetres, and a cut size of 3 millimetres and 5 millimetres. [00055] The operating shaft 610 includes an operating end portion 612 and an engaged end portion 614. The operating end portion 612 may be operatively coupled to the gear assembly 410 of the transmission unit 500. The operating end portion 612 may be provided with a plurality of keys for allowing easy operative coupling with the gear assembly 410, which may include corresponding plurality of keys. The engaged end portion 614 may be operatively coupled to the operating section 620.

[00056] More specifically, the master gear 420 of the gear assembly 410 may be snugly fitted over the operating end portion 612 of the operating shaft 610 (as shown in FIGS. 2, 3 and 4). Such operational coupling allows the gear assembly 410 to transfer the controlled motion to the operating section 620 of the compressor 1000 via the operating shaft 610.

[00057] The operating shaft 610 may be operatively coupled to the gear assembly 410. More specifically, an operating end 612 of the operating shaft 610 may be operatively coupled to the master gear 420, which may be snugly fitted thereon for providing the operative coupling.

[00058] The operative shaft 610 in such configuration may be arranged such that an axis 'A' of the operating shaft 610 is paral lel to an axis ' X' of the driven shaft 10, and the operating shaft 610 and the driving unit 100 are structurally arranged opposite to each other. Such arrangement of the operating shaft 610 and the driving unit 100 adds to the overall compactness of the compressor 1000. Such compactness is very important to reduce the overall size of the compressor 1000 making it easily installable in installation locations that are suffering from shortage of storage spaces. However, it should be also understood that such configuration of the operating shaft 610 with respect to the driving unit 100 should not be construed as a limitation to the present disclosure.

[00059] The operating section 620 forms the core of the compressor 1000, and provides the compression effect in the compressor 1000. More specifically, the operating section 620 compresses an operating medium in the compressor 1 000. Preferably, the operating medium refers to a refrigerant that is required to be compressed in the compressor 1000. Suitable examples of such refrigerants may include, but are not limited to, R-401A, R-404A, R-408A, and the like. In one embodiment, the operating medium may be air.

[00060] In one embodiment, the operating section 620 may be similar to the operating sections existing in the reciprocating type compressors. According to this embodiment, the operating section 620 may therefore include a plurality of compression cylinders 800 (2 compression cylinders shown in FIGS. 1 and 4). Further, it should be noted that the terms 'plurality of compressions cylinders 800' and 'plurality of cylinders 800' may interchangeably used in the present disclosure.

[00061] Each of the plurality of compression cylinders 800 may be similar in construction. Each of the plurality of compression cylinders 800 may be fitted with a piston member 810. The piston member 810 may be capable of reciprocating inside the each of the plurality of compression cylinders 800.

[00062] More specifically, the piston member 810 may be operatively coupled to the operating shaft 610. In an embodiment, the piston member 810 may be operatively coupled to a crankpin 615 of the operating shaft 610 (as shown in FIGS. 1 and 4). The operational coupling of the operating shaft 610 and the piston member 810 of the each of the plurality of compression cylinders 800 allows the piston member 810 to receive driving force transferred via the operating shaft 61 0. This enables the piston member 810 to reciprocate inside the each of the plurality of cylinders 800. It will be apparent to a person skilled in the art that such reciprocation of the piston member 810 in the each of the plurality of compression cylinders 800 will operate on the operating medium inside the each of the plurality of cylinders 800, thereby producing the energy efficient compression effect. Further, the each of the plurality of cylinders 800 may be composed of metallic materials, alloys, or other similar materials suitable.

[00063] Further, the operating section 620 may include at least one valve plate 625 fitted on a top end portion 630 of the each of the plurality of cylinders 800. The at least one valve plate 625 may regulate the suction and discharge of the operating medium acted upon in the each of the plurality of compression cylinders 800. The at least. one valve plate 625 will now be described with reference to FIGS. 6- 7. [00064] FIG. 6 shows a perspective view of a discharge side of the valve plate 625, according to an embodiment of the present disclosure. FIG. 7 is a disassembled view of the discharge side of the valve plate 625. FIG. 8 is a perspective view of a suction side of the valve plate 625, according to an embodiment of the present disclosure. FIG. 9 is a disassembled view of the suction side of the valve plate 625, according to an embodiment of the present disclosure.

[00065] The valve plate 625 includes a seating 626. The seating 626 may be capable of being rested over the top end portions 630 of the plurality of compression cylinders 800. The seating 626 is similar to seating that exists in valve plates known in the art.

[00066] Further, the seating 626 includes a discharge side surface 632 and a suction side surface 634. The discharge side surface 632 includes a plurality of discharge holes 627 disposed on the discharge side surface 632 of the seating 626. The plurality of discharge holes 627 is capable of allowing the compressed operating medium (not shown) to exit from the each of the plurality of compression cylinders 800 during operation of the each of the plurality of cylinders 800. The compressed operating medium as mentioned herein refers to an operating medium in a compressed state, i.e., the operating medium which has been compressed by the action of the piston member 810 of the each of the plurality of cyl inders 800.

[00067] Further, the seating 626 includes a plural ity of suction holes

629 disposed on the suction side surface 634 of the seating 626. The plurality of discharge holes 629 is capable of allowing an operating medium to enter the each of the plurality of compression cylinders 800.

[00068] In an embodiment of the present disclosure, the valve plate 625 is characterized in that a bore size of the plurality of discharge holes 627 is about equivalent to a bore size of the plurality of suction holes 629.

[00069] In another embodiment of the present disclosure, the valve plate 625 is characterized in that a bore size of the plurality of discharge holes 627 is about similar to a bore size of the plurality of suction holes 629. [00070] In yet another embodiment, the bore size of the plurality of discharge holes 627 and the plurality of suction holes 629 may be between about 5 millimetres to about 15 millimetres.

[00071] In an embodiment of the present disclosure, the valve plate 625 may further include a discharge side reed valve 636 attached to the discharge side surface 632 of the seating 626. More specifically, the discharge side reed valve 636 is bolted into holes 641 on the discharge side surface 632 for attaching the discharge side reed valve 636 on the discharge side surface 632. The bolting may be done using one or more bolts 640.

[00072] The discharge side reed valve 636 is capable of operating for allowing the operating medium to flow into the each of the plurality of compression cylinders 800. More specifically, the discharge side reed valve 636 may be capable of opening for allowing the compressed operating medium to flow out of the each of the plurality of compression cylinders 800. The operation of the discharge side reed valve 636 is based on pressure variation inside the each of the plurality of compression cylinders 800 created due to the movement of the piston member 810 therein.

[00073] In^another embodiment, the valve plate 625 may further include a suction side reed valve 638 attached to the suction side surface 634 of the seating 626. More specifically, the suction side reed valve 638 is pinned into the suction side surface 634 using pins 643 that attach the suction side reed valve 638 on the suction side surface 634. _.

[00074] The suction side reed valve 638 is capable of operating for allowing the operating medium to flow into the each of the plurality of compression cylinders 800. More specifically, the suction side reed valve 638 may be capable of opening for allowing the operating medium to flow into the each of the plurality of compression cylinders 800. The operation of the suction side reed valve 638 is based on pressure variation inside the each of the plurality of compression cylinders 800 caused due to the movement of the piston member 810 therein. More specifically, the suction side reed valve 638 may open when a positive pressure exists in the each of the plurality of compression cylinders 800. [00075] Furthermore, the operating section 620 may include at least one head plate 650 (hereinafter referred to as head plate 650). The head plate 650 will now be described with reference to FIGS. 10- 1 1 .

[00076] As shown in FIGS. 1 , 10 and 1 1 , the head plate 650 may be designed to be disposed over the plurality of cylinders 800. More specifically, the head plate 650 may be placed over the discharge side surface 632 of the valve plate 625. The head plate 650 facilitates an entry and exit of the operating medium in the each of the plurality of cylinders 800. More specifically, during operation of the plurality of cylinders 800, the head plate 650 allows an accumulation and discharge of the operating medium over the plurality of cylinders 800. In one embodiment, the head plate 650 may include a bulge 652 extending outwardly from the plurality of cylinders 800. The bulge 652 may be capable of encapsulating the plurality of cylinders 800.

[00077] In one embodiment (as shown in FIG. 1 0), the head plate 650 has a depth of about 15 millimetres to about 30 millimetres, and has a length of about 100 millimetres to about 140 millimetres. However, it should be clearly understood that these dimensions of the head plate 650 are provided for exemplary purposes only and should not be construed as a limitation to the present disclosure.

[00078] In one embodiment, the head plate 650 includes a suction inlet 656 capable of allowing the operating medium to flow into the head plate 650. Particularly, the suction inlet 656 allows the operating medium to flow into the head plate 650 from a reservoir (not shown) capable of storing the operating medium therein.

[00079] In one embodiment, the head plate 650 may further include a division wall 658. The division wall 658 is designed to divide the head plate 650 into two zones, such as Discharge zone (D) and Suction zone (S). Such division also precludes any intervention of the operating medium and the compressed operating medium during operation of the plurality of cylinders 800. The head plate 650 may be placed over the valve plate 625 such that the discharge holes 627 lie in the Discharge zone (D), and the suction holes 629 lie in the Suction zone (S).

It will be clear from FIG. 1 1 that in such embodiment the wall 670 cuts through the suction side 'S' and the discharge side 'D' as compared to merely dividing the head plate 650 into a suction side 'S' and a discharge side 'D', as is the case in FIG. 10.

[00081 ] In another embodiment of the present disclosure, the operating section 620 may include a central spinning rotor (not shown in the figures) having a plurality of vanes attached thereto. The central spinning rotor may be operatively coupled to the operating shaft 610 of the operating unit 700 for transferring the controlled motion of the driven shaft 10 to the central spinning rotor, thereby producing the energy efficient compression effect. It will be apparent to a person skilled in the art that the operating section 620 is similar to operating sections existing in the rotary type compressors. Accordingly, the operating medium may be acted upon by the central spinning rotor to increase a pressure thereof. More specifically, the operating section 620 according to this embodiment may allow the operating medium to get into operation with the central spinning rotor, which using its plurality of vanes may act on the operating medium to increase a pressure of the operating medium.

[00082] In yet another embodiment, the operating section 620 may include operating sections existing in compressors known in the art. For examples, the operating section 620 may be similar to the operating section of a centrifugal type compressor, or other rotary type compressors, such as rotary screw type compressors, and the like.

[00083] In addition to the components as described above, the compressor 1000 may include a pump assembly (not shown).

The pneumatic pump keeps the piston members well lubricated during operation of the compressor 1000.

[00084] Further, the compressor 1000 may additionally include a support stand 860 capable of supporting various components of the compressor 1000. The support stand 860 may be composed of sturdy materials capable of supporting the vigour during the operation of the compressor 1000. The support stand 860 may preferably be composed of metallic materials, such as steel.

[00085] In one embodiment, the compressor 1000 may be hermetically sealed in a casing. The hermetically sealing may be done similar to the sealing methods known in the art. Further, the casing may be similar to the casing known in the art. Such sealing insulates the compressor 1000 from the outer environment. In one embodiment, the compressor 1000 may be oil filled.

[00086] The working of the compressor 1 000 will now be explained. To start the operation of the compressor 1000, the compressor 1000 is required to be connected to an external power supply. More specifically, the driving unit 100 of the compressor 1000 may be required to be operatively coupled to the external power supply. The external power supply may be an electrical power supply available in households or industrial establishments. In case the compressor is required to be part of a car air conditioning system, the external power supply may be an automobile engine.

[00087] The operational coupling of the driving unit 100 to the external power supply enables the driving unit 100 to rotate the driven shaft 10. The rotation of the driven shaft 10 accordingly transfers the motion thereof to the transmission unit 500, and more particularly, the gear assembly 4 1 0 of the transm ission unit 500. Even more particularly, the teeth 14 (gear) configured at the free end portion 12 of the driven shaft 10 may facilitate the transfer of the motion of the driven shaft 10 to the master gear 420 to which it is operatively coupled. This may lead to rotation of the master gear 420.

[00088] The rotation of the master gear 420 controllably transfers the motion of the driven shaft 10 to the operating shaft 610. The rotation of the operating shaft 610 activates the operating section 620. The operating section 620 may act on the operating medium, which may be sucked into the operating section 620 via the head plate 650.

[00089] The sucked operating medium may become accumulated in the head plate 650. Thereafter, the motion of the piston member 8 1 0 in the each of the plurality of cylinders 800 may allow the operating medium to be introduced in the each of the plurality of cylinders 800 via the at least one valve plate 625.

[00090] The moving piston member 810 may then act upon and compresses the operating medium to a desired pressure, thereby providing the energy efficient compression effect. Such compressed operating medium may thereafter be taken out of the plurality of cylinders 800. The compressed operating medium may thereafter be used in a refrigeration system or an air-conditioning system as the case may be. The pump assembly may keep the piston member 810 and the operating shaft 610 well lubricated.

[00091] In another aspect, the present disclosure provides a cooling system 2000 for providing energy efficient cooling. The cooling system 2000 is shown with reference to FIG. 12.

The compressor is characterized in that the transmission unit controllably transfers a motion of the driven shaft to the operating shaft. Further, the compressor is characterized in that the operating shaft transfers the controlled motion of the driven shaft to the operating section of the operating unit. In addition, the compressor is characterized in that the operating shaft and the driving unit are structurally configured opposite to each other such that an axis of the operating shaft is parallel to an axis of the driven shaft.

[00094] In an embodiment of the present disclosure, the heat transfer circuit may be an air conditioning circuit capable of providing energy efficient air conditioning. The air conditioning circuit is similar to the air conditioning circuit known in the art. It will be apparent to a person skilled in the art that such a circuit usually includes a cooling coil and a heating coil in operational communication with the compressor 1000. Further, the air conditioning circuit may additionally include an air circulation sub circuitry including a fan and blower.

[00095] In another embodiment, the heat transfer circuit may include a refrigeration circuit. The refrigeration circuit is similar to the refrigeration circuits employed in conventional refrigeration systems.

[00096] In yet another embodiment, the heat transfer circuit may include a chilling circuit. The chilling circuit is similar to the chilling circuits employed in conventional chilling systems.

[00097] In yet another aspect, the present disclosure provides a compressor capable of producing an energy efficient compression effect. The compressor includes a driving unit having a driven shaft. The driving unit is capable of being connected to an external power source for driving the driven shaft. Further, the compressor includes an operating unit. The operating unit includes an operating shaft operatively coupled to the driven shaft, and an operating section operatively coupled to the operating shaft.

[00098] The operating section includes a plurality of compression cylinders, and at least one valve plate. The at least one valve plate includes a seating capable of being rested over a top end portion of each of the plurality of compression cylinders. The seating includes a suction side surface and a discharge side surface, a plurality of suction holes disposed on the suction side surface of the seating. The plurality of suction holes are capable of allowing an operating medium to flow into the each of the plurality of compression cylinders.

[00099] Further, the seating includes a plurality of discharge holes disposed on the discharge side surface of the seating. The plurality of discharge holes are capable of allowing a compressed operating medium to exit the each of the plurality of compression cylinders. The valve plate is characterized in that a bore size of the plurality of suction holes is about equivalent to a bore size of the plurality of discharge holes.

[000100] The efficiency of the compressor 1000 will now be illustrated with respect to comparative results, which were obtained by comparing the performance of the compressor 1000 (referred to as 'Novel Compressor') with standard compressors available in the market. The comparison was made by noting various performance parameters of the compressors first made offline and then made with integration with a cooling system, which was in this case is a standard 1 .5 Tonne Air conditioning system. The results are as shown in TABLE 1 .

TABLE 1

[000101 ] In the comparative experiment, all the compressors were operated for a long duration of time (about 2-3 hours) in varying conditions to determine various parameters related thereto. In one embodiment, all the compressors were run with no load to give Free Ampere Readings (Column 2 of the TABLE 1 ). In another embodiment, all the compressors were operated for a long duration of time (about 2-3 hours) with full load to give the Load Ampere Readings (Column 3 of TABLE 1 ). The pressure readings and energy were correspondingly obtained and presented in Columns 4 and 5, respectively. [000102] As shown in the TABLE 1 , the Novel Compressor shows lowest Free Ampere reading of about 0.5 Ampere, and Load Ampere reading of about 1.3 Ampere among the comparative compressors, while producing almost the same pressures. This clearly highlights the energy efficiency of the Novel Compressor, which is attributed to its unique design. Further, the Novel Compressor was able to perform the same when integrated with a cooling system, which in this case is a standard 1.5 Tonne Air conditioning system.

[000103] Further, the Novel Compressor gave excellent performance in high ambient temperatures ranges, in which the standard compressors either tripped or showed considerable reduction in performance. The Novel Compressor was able to produce cooling when applied in the cooling system with the outside ambient temperatures in range of about 50 degrees Celsius to about 55 degree Celsius.

[000104] The advantages of the compressor 1 000 are many fold. Firstly, the compressor 1000 is capable of producing an energy efficient compression effect. The energy efficient compression effect is due to the introduction of a transmission unit, such as transmission unit 500, which allows use of a low rating driving unit 100 in the compressor. This makes the compressor 1000 a green solution towards addressing the ever burgeoning cooling requirements.

[000105] Secondly, the compressor 1000 consumes very less energy and is equally effective in addressing the cooling and refrigerating needs of cooling and refrigeration equipments. This is attributed to the to the transmission unit 500 and employing the valve plate 625 and the head plate 650 in the present disclosure.

[000106] Thirdly, the compressor 1 000 is compact despite adding the transmission unit 500. This compactness is mainly because the "driving unit 100 is structurally configured opposite to the transmission unit 500 as described above. This saves valuable installation spaces in households and industrial spaces.

[000107] Fourthly, the compressor 1000 is sturdy and highly durable during operation, thereby adding to its reliability. This is due to the use of highly robust and durably material for the construction of the compressor 1000.

[000108] Fifthly, due to easy connection of the driven shaft 10 with the belt and pulley system 200, the compressor 1000 is capable of being installed into an automobile. Therefore, the compressor 1000 may be capable of driving an air conditioner of an automobile.

[000109] Further, due to the overall configuration of the compressor 1000, it is very easy to maintain and has low maintenance cost. Further, the construction cost of the compressor 1000 is comparatively lower as compared to conventional compressors.

[0001 10] Lastly, the compressor 1000 is of high performance, and may be able to provide sustained performance in high ambient temperatures.
