- Patent Document 1 discloses a refrigeration and air conditioning system including a compressor, an outdoor heat exchanger (also referred to as a condenser), a capillary tube, and an indoor heat exchanger (also referred to as an evaporator).
- the compressor, the outdoor heat exchanger, the capillary tube, and the indoor heat exchanger are connected to each other by piping through which the refrigerant flows. Therefore, the refrigerating and air-conditioning system is configured as a closed system, and the refrigerant circulates in the system while repeating the phase transition between the gas and the liquid.
- the indoor heat exchanger functions as an evaporator and the outdoor heat exchanger functions as a condenser.
- a state of change of the refrigerant in this case will be described.
- the compressor when the compressor is operated, the refrigerant in the state of low-temperature and low-pressure saturated steam is compressed by the compressor and changed to high-temperature and high-pressure superheated steam. Subsequently, the refrigerant in the state of superheated steam exchanges heat with the outside of the system in the condenser to become a room temperature and high pressure liquid.
- the refrigerant in the liquid state at room temperature and high pressure expands by the capillary tube to become low-temperature and low-pressure wet steam.
- the refrigerant in the state of low-temperature and low-pressure wet steam exchanges heat with the outside in the evaporator (indoor heat exchanger), absorbs heat outside the system, completely evaporates, and changes to saturated steam To do.
- the refrigerant circulates in the refrigerating and air-conditioning system while changing in this way, the temperature of the room where the indoor heat exchanger (evaporator) is installed decreases, and the high-temperature and high-pressure heat generated by the compressor is outdoors. As a result, the outdoor air temperature where the outdoor heat exchanger (condenser) is installed rises.
- Patent Document 1 discloses a bubble removing device or the like that can remove vacuum bubbles present in a refrigerant from the refrigerant.
- Patent Document 2 discloses an apparatus for recombining impurities present in a refrigerant or a compound as a refrigerant composition.
- the device described in Patent Document 2 is not a device used as a part of a heat exchanger or a refrigeration air conditioning system (see paragraph 0077).
- the refrigerant circulates repeatedly in the system in a short time while changing the temperature between high and low temperatures. Therefore, when the refrigerating and air-conditioning system is operated for a long time, radical substances and free radical molecules (hereinafter collectively referred to as “radicals”) of the compounds constituting the refrigerant (for example, carbon, hydrogen, fluorine, chlorine). Can be generated in the refrigerant, and hydrogen compounds such as hydrogen fluoride and hydrogen chloride can be generated by ionic bonds.

- the refrigerant containing radicals When the refrigerant containing radicals is introduced from the narrow tube, it flows at a very high speed along the first spiral groove, and a vortex is generated in the main body.
- the radicals that flow along with the super high-speed vortex of the refrigerant are directed outward and are pushed toward the inner peripheral surface of the trunk. Since the first spiral groove is provided on the inner peripheral surface of the trunk portion, radicals flow along the groove while being in contact with the first spiral groove.
- the second spiral groove extending in a spiral shape with respect to the central axis is formed on the outer peripheral surface of the tube portion. For this reason, the refrigerant flows while in contact with the second spiral groove, so that an ultra-high speed vortex is more easily formed. Therefore, even when there are radicals that could not be separated by the first spiral groove, the radicals flow outwardly on the outer peripheral surface of the tube part, and the radicals are directed outward and pushed toward the inner peripheral surface of the trunk part. .

- the radical comes into contact with the first spiral groove for a long time. Therefore, separation of the radicals from the refrigerant and liquefaction of the radicals into the refrigerant composition are further promoted, and the radicals are more easily mixed with the liquid refrigerant. Therefore, radicals present in the refrigerant are easily regenerated into the refrigerant constituent composition.

Therefore, the inner peripheral surface of the trunk portion 110a has a spiral groove 116 (first spiral groove) extending spirally with respect to the central axis (hereinafter referred to as “center axis”) of the trunk portion 110a. That is, in the present embodiment, the spiral groove 116 is constituted by a gap between adjacent metal wires of the cylindrical coil spring 110e.

- the diameter of the metal wire may be about 2 mm.
- the inner peripheral surface (spiral groove 116) of the trunk portion 110a is separated from the outer peripheral surface of the tube portion 114. Therefore, a flow path through which the refrigerant flows is configured between the inner surface of the trunk portion 110a and the outer peripheral surface of the tube portion 114.
- the inner surface of the body portion 110a has an uneven surface in which unevenness is arranged along the flow path (in the opposing direction of the upper end wall portion 110b and the lower end wall portion 110c) due to the presence of the spiral groove 116.
- the total length of the cylindrical coil spring 110e is substantially equal to the total length of the cylindrical body 110d. Therefore, the spiral groove 116 exists over the whole trunk
- the upper end wall portion 110b and the lower end wall portion 110c are constituted by a shallow cap having a disk shape.
- a thin tube 112 having an opening H1 is provided on the outer peripheral edge side of the upper end wall portion 110b.

- the compressor 16 When the compressor 16 operates, the refrigerant in a state of low-temperature and low-pressure saturated steam is compressed by the compressor 16 and changed to high-temperature and high-pressure superheated steam. Subsequently, the refrigerant in the state of superheated steam exchanges heat with the outside of the system in the heat exchanger 24 of the outdoor heat exchange device 18 to become a room temperature and high pressure liquid. At this time, not all of the refrigerant is completely liquid, and radicals may exist in the refrigerant. The liquid refrigerant containing radicals flows into the refrigerant treatment apparatus 100 from the heat exchanger 24 of the outdoor heat exchange apparatus 18 together with the radicals through the narrow tube 112 (opening H1).
- the refrigerant flows into the refrigerant processing apparatus 100
- the refrigerant flows at an ultra high speed while colliding with the spiral groove 116. Therefore, an ultra-high speed vortex of the refrigerant is formed in the main body 110. Therefore, the radicals that flow along with the super-high-speed vortex of the refrigerant go outward and are pushed toward the inner peripheral surface of the trunk portion 110a. Since the spiral groove 116 is provided on the inner peripheral surface of the trunk portion 110 a, radicals flow along the spiral groove 116 while being in contact with the spiral groove 116.

- the refrigerant When the refrigerant flows to the end in the main body 110 of the pipe part 114, the refrigerant hits the upper end wall part 110b and the direction of the flow is reversed, and the flow path in the pipe part 114 from the opening of the end of the pipe part 114 is reversed. It flows to 114b. Therefore, the refrigerant in which the radicals are separated and regenerated and is in the liquid state at room temperature and high pressure flows out from the opening H2 of the pipe portion 114 (see the white arrow in FIG. 3).
- the refrigerant in the liquid state at room temperature and high pressure is expanded by the expansion valve 19 and the capillary tube 20 to become low-temperature and low-pressure wet steam.

It flows in the order of the valve 12 and the four-way valve 14 and circulates in the refrigeration air conditioning system 1. As the refrigerant circulates in the refrigeration and air conditioning system 1 in this manner, the temperature of the room in which the evaporator (indoor heat exchange device 10) is installed decreases, and the condenser (outdoor heat exchange device 18). The outdoor air temperature where the is installed rises.

- the heat exchanger included in the indoor heat exchanger 10 functions as a condenser
- the heat exchanger 24 included in the outdoor heat exchanger 18 functions as an evaporator.
- the compressor 16 When the compressor 16 operates, the refrigerant in the state of low-temperature and low-pressure dry steam is compressed by the compressor 16 and changed to high-temperature and high-pressure superheated steam. Subsequently, the refrigerant in the state of superheated steam flows in the order of the four-way valve 14 and the three-way valve 12 and flows into the indoor heat exchange device 10, and performs heat exchange with the outside in the heat exchanger of the indoor heat exchange device 10. It becomes a liquid at room temperature and high pressure.
- the refrigerant in a liquid state at room temperature and high pressure is expanded by the expansion valve 19 and the capillary tube 20 to become low-temperature and low-pressure wet steam.
- the refrigerant in the state of low-temperature and low-pressure wet steam flows into the refrigerant processing apparatus 100 to recover its function.
- the outdoor heat exchange device 18 exchanges heat with the outside of the system and is heated to change into a normal temperature gas.
- the refrigerant is the compressor 16, the four-way valve 14, the three-way valve 12, the indoor heat exchange device 10, the two-way valve 22, the expansion valve 19, the capillary tube 20, the refrigerant processing device 100, the outdoor heat exchange device 18 (heat exchanger). 24) and flows in the order of the four-way valve 14 to circulate in the refrigeration air conditioning system 1.
- the refrigerant circulates in the refrigeration air conditioning system 1 while changing in this way, the temperature of the room in which the evaporator (indoor heat exchange device 10) is installed rises, and the condenser (outdoor heat exchange device 18).
- the outdoor air temperature where is installed decreases.
- the inner surface of the trunk portion 110a has the spiral groove 116 extending spirally with respect to the central axis.
- separation of radicals is promoted, and individual radicals become liquid refrigerants of the refrigerant composition again. Therefore, separation of the radicals present in the refrigerant from the refrigerant and liquefaction of the radicals into the refrigerant composition are promoted. Accordingly, radicals present in the refrigerant can be regenerated into the refrigerant composition.
- the spiral groove 116 exists over the entire length of the trunk portion 110a. Therefore, radicals will come into contact with the spiral groove 116 for a long time. Accordingly, separation of radicals from the refrigerant and regeneration into the refrigerant are further promoted.
- the spiral groove 116 is constituted by a gap between adjacent metal wires of the cylindrical coil spring 110e. Therefore, by using the cylindrical coil spring 110e, the spiral groove 116 can be configured simply and at low cost.
- the opening H1 of the thin tube 112 and the opening H2 of the tube portion 114 are not opposed when viewed from the central axis direction. Therefore, it becomes difficult for the refrigerant to flow directly from the opening H1 of the thin tube 112 to the opening H2 of the tube portion 114.
- separation of the refrigerant and the refrigerating machine oil is prevented so that the refrigerating machine oil flowing together with the refrigerant does not become a refrigerating machine oil pool in the pipe portion 114. Therefore, the refrigerant and the refrigerating machine oil (lubricating oil) flow to the opening H2 of the pipe portion 114 with the best mixing ratio. Further, since the refrigerant flowing into the main body 110 from the narrow tube 112 collides with the spiral groove 116 (cylindrical coil spring 110e) at an ultra high speed, the efficiency of gas-liquid separation is increased.
- the outer peripheral surface of the inner tube portion 114a of the tube portion 114 has a spiral groove 118 and a linear groove 119 extending spirally with respect to the central axis. Therefore, the refrigerant flows while in contact with the spiral groove 118 and the linear groove 119, so that an ultra-high speed vortex is more easily formed. Accordingly, the radicals can easily move outward, and the radical separation is further promoted.
- the spiral groove 118 is constituted by a male screw. Therefore, the spiral groove 118 can be configured easily and at low cost.
- a linear groove 119 extending in the central axis direction is formed on the outer peripheral surface of the pipe portion 114. Therefore, liquefaction of radicals into the refrigerant composition is further promoted, and the spiral groove 118 can be configured simply and at low cost.
- the depth of the linear groove 119 is the same as the depth of the spiral groove 118, since the refrigerant containing radicals flows in the spiral groove 118, the liquid refrigerant moves upward along the linear groove 119. In doing so, the liquid refrigerant flows together with the refrigerant containing radicals and is agitated. In this case, although the liquid refrigerant does not need to be stirred, unnecessary energy is consumed in the liquid refrigerant.
- the depth of the linear groove 119 is smaller (shallow) than the depth of the spiral groove 118. Therefore, the refrigerant containing radicals flowing in the spiral groove 118 is less likely to act on the liquid refrigerant flowing in the linear groove 119. Therefore, the energy required to push the liquid refrigerant upward can be further reduced, and further energy saving can be achieved.
- the refrigerating and air conditioning system 1 can be configured by adding the refrigerant processing apparatus 100 to an existing refrigerating and air conditioning system. Therefore, the operation efficiency of the entire refrigerating and air-conditioning system 1 can be increased only by adding the refrigerant processing device 100, which can greatly contribute to energy saving. In addition, when adding the refrigerant processing apparatus 100, it is not necessary to replace the refrigerant in the existing refrigeration air conditioning system even in a model having a reduced air conditioning capability.
- the spiral groove 116 is configured by the cylindrical coil spring 110e, but the spiral groove may be formed directly on the inner wall surface of the cylindrical body 110d.
- the cross-sectional shape of the groove various shapes such as a U shape, a triangular shape, a quadrangular shape, and other different shapes can be adopted.
- the spiral groove 116 has a length substantially equal to the entire length of the cylindrical body 110d.
- the inner surface of the body 110a has at least the spiral groove 116 on the opening H1 side of the narrow tube 112 through which the refrigerant flows in and out. If you do.
- the cylindrical body 110d has a cylindrical shape, but various shapes such as a polygonal shape such as a hexagonal shape or a quadrangular shape and an elliptical shape can be adopted as the shape of the cylindrical body 110d.
- the cross-sectional shape of the metal wire of the cylindrical coil spring 110e in the present embodiment various shapes such as a circular shape and a rectangular shape can be adopted.
- the spiral groove 118 of the pipe portion 114 is configured by a male screw, but a metal wire is spirally wound around the outer peripheral surface of the tube portion 114, and the spiral groove 118 is configured by a gap between adjacent metal wires. May be.
- the tube portion 114 may not have the spiral groove 118.
- the pitch of the spiral grooves 116 and 118 may be constant or may vary along the central axis direction.
- a throttle member 120 may be provided in the pipe portion 114.
- 14 throttle members 120 having a flat plate shape are provided in the pipe portion 114.
- the number of throttle members 120 in the tube portion 114 may be about 5 to 15, or may be at least one.
- the throttle member 120 only needs to provide a channel area smaller than the channel area of the pipe portion 114.
- the flow path area provided by the throttle member 120 is such that the pressure on the upstream side increases due to the presence of the throttle member 120 and the compressor 16 located on the upstream side of the throttle member 120 is not loaded, or the load is very small. It is good to set so that it may become few.
- the channel area provided by the throttle member 120 can be set to about 2/3 to 3/4 of the channel area provided by the pipe portion 114, for example.
- the shape of the diaphragm member 120 is not limited to a flat plate shape, and various shapes can be employed. In the case where the throttle member 120 has a flat plate shape, as shown in FIG. 7, the throttle member 120 has at least one through hole 120a (9 through holes 120a in FIG. 7) penetrating in the thickness direction. You may do it.
- the pressure on the downstream side of the throttle member 120 is lower than the upstream side of the throttle member 120 due to the presence of the throttle member 120. For this reason, the force from the refrigerant acting on the radical aggregate is relatively low. Therefore, the separation of radicals from the refrigerant and the liquefaction of radicals into the refrigerant composition can be further promoted.
