FIG. 2 is a schematic diagram illustrating the structure and operation of the rectifier illustrated in FIG. 1.
3 is a block diagram of a two-stage compression-absorbing heat pump system according to another embodiment of the present invention.
4 is a schematic diagram illustrating the structure and operation of the rectifier illustrated in FIG. 3.

1 is a one-stage compression-absorbing heat pump system 100 according to one embodiment of the present invention. Referring to FIG. 1, the first stage compression-absorbing heat pump system 100 includes an expansion mechanism 150, a desorber 110, a compressor 130, a pump 140, an absorber 120, and an intermediate heat exchanger ( 160 and rectifier 1.

The expansion mechanism 150 expands the high temperature, high pressure, high concentration refrigerant-absorbent mixture introduced from the absorber 120 and changes it into the low temperature, low pressure, high concentration refrigerant-absorbent mixture. The refrigerant-absorber may be various combinations, and as the refrigerant-absorber combination, water-LiBr combination, ammonia-water combination, R22-DEGDME combination, R22-DMETEG (E181) combination, carbon dioxide-acetone combination, and TFE-DMETEG (E181 ) And the like, and in particular, when the ammonia-water combination is used, oxide-based nanoparticles other than metals may be applied to ensure corrosion resistance and stability.

The absorber 110 introduces the low temperature, low pressure refrigerant-absorbent mixture from the expansion mechanism 150. In the solver 110, hot water as a heat source is supplied from the outside, and a refrigerant having a high vapor pressure is mainly evaporated from the refrigerant and the absorbent. The compressor 130 compresses the refrigerant evaporated from the desorber 110. The hot water is lowered in temperature by heat exchange with the absorber 110. The hot water is lowered as the cold water at the demand.

The pump 140 pressurizes the refrigerant-absorbent mixture in which the partial refrigerant is evaporated from the desorber 110 and becomes a concentrated solution, and supplies the pressure to the absorber 120. In the absorber 120, a high temperature and high pressure refrigerant discharged from the compressor 130 flows in and is absorbed by the refrigerant-absorbent mixture in the concentrate state. Cooling water flows into the absorber 120 to absorb the heat generated in the absorption process and send it to the outside. The heat is absorbed to increase the temperature of the cooling water, which is used as hot water for demand.

The intermediate heat exchanger 160 discharges from the pump 140 and flows into the absorber and the high pressure and high pressure refrigerant-absorbent mixture and the absorber 120 flows into the expansion mechanism 150. Heat exchange the refrigerant-absorbent mixture.

The refrigerant flowing into the compressor 130 partially includes a liquid absorbent. In the case of the ammonia combination, it can contain about 0.3% water. When the absorbent is introduced into the compressor 130, liquid compression may occur in the compressor 130, and the compressor 130 may be damaged. In addition, since the compressor 130 includes a material such as iron, when the absorbent (particularly, water) is introduced, there is a great risk of corrosion of the compressor 130.

In order to solve this problem, the rectifier 1 is installed. With reference to FIG. 2, the said rectifier 1 is demonstrated in detail below.

The rectifier 1 includes a flow pipe 60, the first rectifying module 10, the second rectifying module 20, the storage unit 110, the third heating means 30 and the absorbent removing means 40. do. The storage unit 110 has a structure that is integral with the resolver 110. The flow pipe 60 is in communication with the upper portion of the resolver 110. The desorber 110 is formed with an inlet 111 through which the high concentration of the refrigerant-absorbent mixture is introduced from the expansion mechanism 150, and a refrigerant-absorbent mixture of the rare solution flows out by the pump 140 at the lower portion thereof. An outlet 112 is formed. In the desorber 110, the liquid refrigerant-absorber is stored in the lower space, and the refrigerant in the gaseous phase is mainly present in the upper space.

The first rectifying module 10 includes a first heating means 11, a first cooling means 12, and a first heat transfer means 13. The first heating means 11 heats the liquid refrigerant-absorbent mixture in the desorber 110, and evaporates the refrigerant from the refrigerant-absorbent mixture to transfer the evaporated refrigerant into the flow pipe 60. It flows to the compressor 130 through. The first heating means 11 has a heating coil structure using hot water. However, the present invention is not limited thereto, and various devices such as an electric heater may be used as the first heating means 11.

The first cooling means 12 cools and condenses the absorbent contained in the evaporated refrigerant to remove it from the evaporated refrigerant. The first cooling means 12 has a cooling coil structure using cooling water, but the present invention is not limited thereto.

The portion in which the first cooling means 12 is installed in the flow pipe 60 is formed to be inclined downward. Therefore, the absorbent condensed by the first cooling means 12 moves to flow back to the flow pipe 60 to be recovered to the absorber 110.

The absorbent cold condensed by the first cooling means 12 is substantially a refrigerant-absorbent mixture of the concentrated solution. This is because some refrigerant is absorbed by the absorbent while the absorbent is condensed. The refrigerant-absorbent mixture of the concentrate is introduced into the first heat transfer means 13. The portion in which the first heat transfer means 13 is installed in the flow pipe 16 is formed in the vertical direction. The first heat transfer means 13 includes a first Raschig ring packing element 13a and meshes 13b and 13c provided at both ends of the first Raschig ring packing element 13a. do. The high temperature refrigerant evaporated from the desorber 110 and the refrigerant-absorbent mixture of the concentrated solution in the first lashing packing member 13a are subjected to contact heat transfer, and thus some refrigerant from the refrigerant-absorbent mixture of the concentrated solution. Is evaporated and flows along the flow pipe 60. Accordingly, since the concentration of the refrigerant-absorbent mixture is recovered to the desorber 110 in a state where the concentration of the refrigerant-absorbent mixture is lowered, the concentration of the liquid refrigerant-absorbent mixture flowing out from the desorber 110 through the pump 140 is 35%. It can be lowered below.

The second rectifying module 20 is installed after the first rectifying module 10 in the flow pipe (60). The second rectifying module 20 has a structure in which one or a plurality of unit modules are arranged in series. A second partition wall (not shown) is provided between the unit modules to partially block the flow of the refrigerant in the flow pipe 60. However, the second partition wall (not shown) is formed so as not to interfere with the backflow of the refrigerant-absorbent mixture condensed and flows in the flow pipe 60. In the present embodiment, only one unit module is provided, but the present invention is not limited thereto, and the purity of the refrigerant flowing into the compressor 130 and the concentration of the rare refrigerant refrigerant-absorbent mixture pressurized by the pump 140 are adjusted. In order to control the number of the unit module is adjusted. That is, to increase the purity of the refrigerant and to lower the concentration of the rare solution, the number of unit modules may be increased.

A first partition 51 is installed between the unit module and the first cooling means 12. The first partition 51 partially blocks the flow pipe 60 but does not impede the backflow of the condensed refrigerant-absorbent mixture flowing from the unit module.

The unit module includes a second heating means 21, a second cooling means 22, and a second heat transfer means 23. The second heating means 21 increases the temperature by heating the refrigerant passing through the first cooling means 12. The increase of the temperature is to efficiently perform the removal of the absorbent in the refrigerant in the second cooling means 22 and the second heat transfer means 23 in the future. As the second heating means 21, a heating coil using hot water is provided. The second cooling means 22 cools and condenses the absorbent contained in the refrigerant to remove it from the refrigerant. The second cooling means 22 has a cooling coil structure using cooling water, but the present invention is not limited thereto.

The second heat transfer means 23 is a refrigerant condensed by the second cooling means 22 (the refrigerant-absorbent mixture in a substantially concentrated solution state) and the refrigerant heated by the second heating means 21. Contact heat exchange between the evaporates the refrigerant in the condensed absorbent. The second heat transfer means 23 includes a second lashing packing member 23a and meshes 23b and 23c provided at both ends of the second lashing packing member 23a. The structure and function of the second heat transfer means 23 may refer to the first heat transfer means 13 described above.

The unit module is installed in the flow pipe 60 has an inclined structure in which the upper part and the lower part are spread with each other in a "c" shape as a whole. That is, the portion in which the second heating means 21 and the second cooling means 22 are installed is inclined downward in the flow pipe 60, and the portion in which the second heat transfer means 23 is installed in the vertical direction. Is formed. Since the second rectifying module 20 has a structure in which the unit module is repeated in series, the structure is simple and various modifications are possible.

The third heating means 30 in the flow pipe 60 is installed after the second rectification module 20. The third heating means 30 performs a function of overheating the refrigerant flowing into the compressor 130. This is to prevent the liquid compression in the compressor (130). A portion in which the third heating means 30 is installed in the flow pipe 60 is also formed to be inclined. A third partition 53 is formed between the third heating means 30 and the second rectifying module 20 to block a portion of the flow pipe 60.

The absorbent removing means 40 is installed after the third heating means 30 in the flow pipe 60. The absorbent removing means 40 performs a function of removing the absorbent remaining in the refrigerant. The absorbent removing means 40 includes a mesh 41 and a shade member 42. The mesh 41 and the shade member 42 collide with the refrigerant to remove the absorbent contained in the refrigerant, and recover the absorber 110 along the flow pipe 60 by gravity. The portion in which the absorbent removing means 40 is installed in the flow pipe 60 is formed in the vertical direction.

As described above, since the purity of the refrigerant flowing into the compressor passage 130 by the rectifier 1 is very high (about 99.5% or more in the ammonia / water mixture), the compressor may have a liquid compression problem and Corrosion problems can be easily solved. Furthermore, the purity of the refrigerant flowing into the compressor 130 may be adjusted by adjusting the number of unit modules of the second rectifying module 20, and the refrigerant-absorbent mixture of the rare solution pressurized by the pump 140 may be adjusted. The concentration is also adjustable.

3 illustrates a two stage compression-absorbing heat pump system 200 according to another embodiment of the present invention. The same reference numerals as in the above-described embodiment indicate the same members. Hereinafter, differences from the above-described embodiment will be mainly described.

Referring to FIG. 3, the two-stage compression-absorbing heat pump system 200 includes an expansion mechanism 250, a desorber 210, a low pressure compressor 231, a high pressure compressor 232, and an intermediate cooling control valve 255. ), A solution return valve 257, a pump 240, an absorber 220, an intermediate heat exchanger 260, an intermediate cooler 290, and a rectifier 1 ′.

The expansion mechanism 250 expands the high-temperature, high-pressure refrigerant-absorbent mixture introduced from the absorber 220 to change into the low-temperature, low-pressure refrigerant-absorbent mixture.

The absorber 210 introduces the low-temperature, low-pressure, high concentration refrigerant-absorbent mixture from the expansion mechanism 250. The desorber 210 is supplied with hot water as a heat source from the outside, and the refrigerant having a high vapor pressure is mainly evaporated from the refrigerant and the absorbent. The hot water is lowered in temperature by heat exchange with the absorber 210, and the hot water is lowered as the cold water at the demand.

The low pressure compressor 231 compresses the refrigerant evaporated from the desorber 210 and introduces the refrigerant into the middle cooler 290. The pump 240 pressurizes the refrigerant-absorbent mixture in which some refrigerant is evaporated from the desorber 210 and becomes a concentrated solution, and supplies it to the absorber 220. In addition, a portion of the low temperature refrigerant-absorbent mixture discharged from the pump 240 branches and flows into the intermediate cooler 290. The intermediate cooling control valve 255 controls the flow rate of the refrigerant-absorbent mixture flowing into the intermediate cooler 290.

In the intermediate cooler 290, the medium pressure refrigerant discharged from the low pressure compressor 231 is mixed with the low temperature refrigerant-absorbent mixture introduced from the pump 240 to lower the temperature. The intermediate cooler 290 is of flash type. The liquid refrigerant-absorbent mixture in the intermediate cooler 290 is reduced in the solution return valve 257 and recovered to the desorber 210. The refrigerant in the gaseous phase in the intermediate cooler 290 flows into the high pressure compressor 232 and is compressed, and then flows into the absorber 220. By the intermediate cooler 290, the compression work of the high pressure compressor 232 is reduced.

In the absorber 220, a high temperature and high pressure refrigerant discharged from the high pressure compressor 232 is introduced and absorbed by the refrigerant-absorbent mixture in the concentrate state introduced from the pump 240. Cooling water flows into the absorber 220, absorbs heat generated in the absorption process, and sends it to the outside. The heat is absorbed to increase the temperature of the cooling water, which is used as hot water for demand.

The intermediate heat exchanger 260 is discharged from the pump 240 and flows out of the absorber 220 and the high-temperature, high-pressure refrigerant-absorbent mixture introduced into the absorber 220 and flows into the expansion mechanism 250. Heat the high pressure refrigerant-absorbent mixture.

The rectifier 1 ′ removes the absorbent contained in the refrigerant, and introduces a high purity refrigerant into the low pressure compressor 231. 4 shows a schematic diagram of the rectifier 1 ′. In Fig. 4, the same reference numerals as in the above-described embodiment indicate the same members.

The difference between the rectifier 1 ′ and the rectifier 1 of FIG. 2 is that the refrigerant passing through the rectifier 1 ′ flows into the low pressure compressor 231. In addition, the insulator 210 integral with the storage unit of the rectifier 1 'is further provided with an inlet 213 through which the refrigerant-absorbent mixture of the concentrate is introduced from the intermediate cooler. That is, the insulator 210 has not only the inlet 211 into which the refrigerant-absorbent mixture of the agricultural solution flows from the expansion mechanism 250 and the outlet 212 that flows out of the pump 240, but also the inlet ( 213 is further formed. Except for this difference, the structure and action of the rectifier 1 ′ are substantially the same as the structure and action of the rectifier 1 described above, and thus a detailed description thereof will be omitted.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
