Conventional absorption chillers or cold / hot water generators can be composed of cold room, evaporator, absorber, regenerator, condenser and cooling tower. Water is used as a refrigerant. Water evaporates in the evaporator, generates cold heat, and phase-changes with water vapor. Then, the water is absorbed into the absorption liquid in the absorber, and is then phase-changed into water vapor through heating in the regenerator. The cooling tower is cooled by the total amount of heat (the amount of heat that is generated and the amount of steam that flows into the condenser from the regenerator). It is necessary to make the cooling water of the proper temperature in the condenser, so that the burden on the temperature drop of the cooling tower is increased, and the cooling water flow rate is increased to waste a great amount of energy in the production and circulation of a large amount of cooling water.
According to the present invention, by separating the absorber and the condenser, the cooling and condensing are separated from each other in the optimum temperature drop range, thereby reducing the burden of decreasing the large temperature drop due to the sequential cooling and condensation , The condensation is moved to the natural circulation by the pressure difference of the steam in the separately installed exposed condenser 21 so as not to cause additional energy to be cooled and to circulate only the cooling water to be cooled in the absorber, Respectively.

[0001] The present invention relates to an absorption type chiller with improved condensing system,

Absorption refrigerator structure

     Conventional absorption chiller or cold / hot water heater can generate cold and hot as one device, so it is more advantageous in terms of space problem and economical efficiency than using two heating and heating devices, It is very favorable. Application No. 10-2005-0064388 [Refrigerant Regeneration Method and Refrigerant Regeneration Method in Absorption Refrigeration Cycle] is an invention for complementing a control system for detecting the level of a refrigerant for regenerating an appropriate refrigerant while saving energy, and Application No. 20-2012- 0002107 [Absorption refrigerator] is an invention in which a method of regenerating a refrigerant is changed from a heating type to an integral type. In the absorption type refrigerator or the absorption type cold / hot water generator, a closed loop circuit is simultaneously formed in the absorber and the heat exchanger tube in the condenser, and cooling and condensation are sequentially repeated with the cooling water flowing into the inside. The temperature drop due to the two heat sources of the absorber and the condenser becomes large and the cooling water becomes large, so that the cooling performance of the cooling tower is greatly burdened. In addition, since the conventional system uses a condenser in which cooling water circulates inside the condenser, the structure of the entire system becomes complicated.

     In the present invention, by separating the cooling system of the absorber and the condenser, cooling is performed in each of the devices, and the temperature drop which is largely caused by the sequential continuous cooling is divided into two, thereby widening the cooling water temperature holding width. The condenser of the present invention can be cooled by the cooling medium from the outside instead of the cooling water flowing inside the condenser, and the steam generated in the regenerator is introduced into the exposed condenser by itself due to the pressure difference. Do not use the circulating power of.

     The evaporator 12 and the condenser 14 are separated from each other so that the cooling and condensation are separated from each other in the proper temperature range. The movement of the steam to the condenser (21) is solved by moving it to the natural circulation by the pressure difference of the steam

     The conventional absorption refrigerator or the cold / hot water heater calculates the total amount of heat (the amount of heat of the obtained cold heat, which is the sum of the amount of heat generated by the vapor generated in the evaporator 11 and absorbed in the absorber 12 and the amount of heat introduced into the condenser 14 by the regenerator 13) And the cooling water whose temperature rises while cooling the absorber 12 is required to cool the condenser 14 in the following order, so that the temperature of the absorber 12 ) And the condenser (14) is also increased, so that the flow rate of the cooling water is increased, wasting a lot of energy in the production and circulation of a large amount of cooling water.

     In the present invention, it is preferable that the first cooling system, not the sequential cooling system, be used to cool the absorber 12 and the condenser 14 so that the refrigeration system and the condenser system are separate from each other The second condensation is a separately installed condenser (21), which moves the steam in a natural circulation manner by pressure difference, thereby eliminating the need for additional energy to circulate the cooling medium. Only the cooling water to be cooled is circulated so that the circulating cooling water flow rate is drastically reduced. In addition, a condenser-coupled cooling tower (70) for installing a vertical type outdoor condenser (83) in the inner space is proposed to minimize the installation space, thereby drastically reducing the installation cost. By using the cooling residual heat of the exhaust air generated in the process of cooling the cooling water And is used for condensing the vertical type outdoor condenser 83 to maximize the cooling efficiency.

     1 is an explanatory diagram of a conventional absorption refrigerator. The absorption type cold / hot water generator also has a mode of generating cold heat, but it is typically described as an absorption type refrigerator. In the conventional absorption type refrigerator, cold heat application unit 10, evaporator 11, absorber 12, regenerator 13, condenser 14 and cooling tower 15 are connected by piping to generate cold heat and hot heat. A vaporizing heat exchange tube 116 is installed inside the sealed evaporator 11 and a refrigerant spraying device 16 is installed on the upper part of the evaporation heat exchange tube 116. The refrigerant spraying device 16 is installed in the evaporator 11 through the upper refrigerant spraying device 16, The evaporation heat exchange tube 116 is connected to the cold heat source 10 through the closed circulation pipe and the refrigerant 112 is supplied to the lower part of the evaporator 11, And the evaporator body passage 117 is connected to the evaporator 11 and the absorber 12 in such a manner that the evaporator 11 and the absorber 12 penetrate through the absorber 12. An absorption heat exchange tube 115 is installed inside the sealed absorber 12, And an absorber solution outflow pipe 19 is provided on the pipe so that the absorbent solution outflow pipe 122 is provided so as to pass through one side of the regenerator 13 from the lower part of the inside of the absorber 12, Through the absorbing solution injector (17) inside the absorber (12) The absorbing solution heat exchanger 111 is installed so that the solution flowing through the absorbing solution outflow pipe 122 and the solution flowing into the absorbing solution inflow pipe 123 is installed to be absorbed in the lower part of the inside of the absorber 12 The solution 113 is filled and the heating device 110 is installed so as to heat the regenerator 13 and the condenser body passage 118 is connected to the regenerator 13 and the condenser 14 so as to pass therethrough, A condensation heat exchange tube 114 is installed inside the condenser 14 and a refrigerant outflow pipe 120 is installed to one side of the refrigerant injection pipe 121 from the lower part of the inside of the condenser 14 so as to pass through the T branch, The cooling water pipe 119 is installed so that the cooling water circulation circuit of the cooling tower 15 is formed and the evaporator 11 and the evaporator body passage 117 are connected to the absorber 12 And a vacuum pump (not shown) for lowering the pressure of the space to be constituted. The regenerator 13 may be constituted by one unit and may be constituted by a high-temperature regenerator and two low-temperature regenerators such as a dual efficiency absorption type refrigerator. The low temperature regenerator heats up by using the latent heat of water vapor generated in the high temperature regenerator. The working principle is as follows. The refrigerant is injected through the refrigerant injector 16 while the vacuum pump is operated to maintain the pressure of the space constituted by the evaporator 11, the evaporator body passage 117 and the absorber 12 at a low pressure of about 0.01 atm, The refrigerant vaporizes to generate water vapor of about 5 ° C. and the evaporation heat exchange tube 116 is cooled to provide the cold heat source 10 with cold heat which is passed through the evaporator body passage 117, The absorbing solution injected into the absorber 12 is absorbed by the absorbing solution 113 having a low vapor pressure injected into the absorbing solution injector 17, and the cooling process is repeated. As the absorbing solution 113, an aqueous solution of sodium chloride (NaCl), a solution of lithium bromide (LiBr) and the like are used. In the absorber 12, the heat generated as the water vapor is absorbed by the absorbing liquid is cooled by the cooling water flowing into the absorption heat exchange tube 115. The absorbing solution 113 having the reduced concentration absorbed from the evaporator 11 is introduced into the regenerator 13 through the absorbing solution outlet pipe 122 by the absorbing solution outlet pump 19 and the regenerator 13 The diluted absorbing solution 113 evaporates water vapor and increases the concentration of the absorbing solution 113. The absorbing solution 113 having a higher concentration flows back to the absorber 12 through the absorption solution inflow pipe 123, Repeat the process. The temperature of the absorption liquid 113 in the absorption liquid outlet pipe 122 is low and the absorption liquid 113 flowing in the absorption liquid inlet pipe 123 has a high temperature so that heat exchange is carried out between them through the absorption liquid heat exchanger 111 The temperature of the absorbing solution 113 flowing into the regenerator 13 is increased and the temperature of the absorbing solution 113 flowing into the absorber 12 is lowered to increase the thermal efficiency. The water vapor generated in the regenerator 13 flows into the condenser 14 and is returned to liquid water as a refrigerant by the cooling water flowing in the condensation heat exchange tube 114 installed in the condenser 14 to be returned to the evaporator 11) and completes one cycle of circulation. That is, the heat amount corresponding to the cold heat obtained in the evaporator 11 is transferred to the absorber 12, and the refrigerant is vaporized by applying the heat corresponding thereto again in the regenerator 13 to move to the condenser 14, Cooling water should be removed from the absorber 12 and the amount of heat generated in the condenser 14, which is about twice the amount of the obtained heat. In addition, since the cooling water circulates sequentially through the absorber 12 and the condenser 14 to cool down, the temperature drop increases and the burden on the cooling tower increases, and the flow rate of the cooling water is significantly increased.

Since the absorption type cold / hot water generating machine also has a mode of generating cold heat, it is natural that the present invention can be applied, but the absorption type refrigerator will be described as a typical example.

The refrigerant spraying device 16 is installed in the evaporator 11 through the upper refrigerant spraying device 16, The evaporation heat exchange tube 116 is connected to the cold heat source 10 through the closed circulation pipe and the refrigerant 112 is supplied to the lower part of the evaporator 11, And the evaporator body passage 117 is connected to the evaporator 11 and the absorber 12 in such a manner that the evaporator 11 and the absorber 12 penetrate through the absorber 12. An absorption heat exchange tube 115 is installed inside the sealed absorber 12, And an absorber solution outflow pipe 19 is provided on the pipe so that the absorbent solution outflow pipe 122 is provided so as to pass through one side of the regenerator 13 from the lower part of the inside of the absorber 12, Through the absorbing solution injector (17) inside the absorber (12) The absorbing solution heat exchanger 111 is installed so that the solution flowing through the absorbing solution outflow pipe 122 and the solution flowing into the absorbing solution inflow pipe 123 is installed to be absorbed in the lower part of the inside of the absorber 12 A heating device 110 is installed so as to heat the regenerator 13 with the solution 113 filled therein and an exposed condenser 21 in which a condensing passage (not shown) Is connected to one side of the upper side of the regenerator 13 so as to penetrate the condensing flow inlets of the exposed condenser 21 and the condensate flow outlets of the exposed condenser 21 and one side of the refrigerant injection pipe 121 are passed through the refrigerant outflow pipe The inlet of the cooling tower 15 and the inlet of the absorption heat exchange tube 115 are connected to the cooling water outlet pipe 24 and the outlet of the cooling tower 15 and the absorption heat exchange tube 115 are connected to the cooling water inlet pipe 23 Connect the cooling tower (15) - the absorption heat exchange tube (115) - again The cooling water circulation circuit of the cooling tower 15 is formed and the cooling water circulation pump 22 is installed on the channel of the cooling water inflow pipe 23 or the cooling water inflow pipe 24. The evaporator 11, And a vacuum pump (not shown) for lowering the pressure of the space constituted by the vacuum pump 12 is provided. The absorption solution 113 may be an aqueous solution of lithium bromide (LiBr) and the refrigerant 112 may be water (H2O). The working principle is as follows.

In the absorber 12, the heat generated as the water vapor is absorbed by the absorbing liquid is cooled by the cooling water flowing into the absorption heat exchange tube 115. The absorption liquid 113 having a reduced concentration by absorbing water vapor is introduced into the regenerator 13 through the absorption liquid outlet pipe 122 by the absorption liquid outlet pump 19 and is supplied to the heating device 110 The dilute absorbing solution 113 evaporates water vapor and repeats the process of circulating the absorbing solution 113 having a higher concentration and increasing the concentration to the absorber 12 through the absorbing solution inflow pipe 123. The steam generated in the regenerator 13 flows into the exposed condenser 21 and is discharged to the outside and then returned to the water and then flows back into the evaporator 11 through the refrigerant outflow pipe 120 to complete a cycle of circulation. That is, the amount of heat corresponding to the amount of heat received by the evaporator 11 is transferred to the absorber 12, and the refrigerant is vaporized by applying the heat corresponding thereto again to the evaporator 11, 11 is removed from the cooling tower 15 through the absorption heat exchange tube 115 inside the absorber 12 so that the flow rate of cooling water is reduced and the burden on the cooling tower 15 is also reduced . Heat generated in the regenerator (13) is removed from the exposed condenser (21). Since the heat of the absorber 12 and the regenerator 13 are separately removed from the cooling tower 15 and the exposed condenser 21 respectively, the cooling load of the cooling tower 15 and the exposed condenser 21 can be reduced. The number of cooling pipes increases from two to four, but since the thickness of the pipes becomes narrow, there is no significant difference in the total sectional area of the cooling pipes.
