Install used cold-producing medium and be the above mix refrigerant of binary or binary, absorbent is for absorbing the solvent of these cold-producing mediums, and balanced gas is that density is little, does not react, is insoluble to the gas of absorbent with cold-producing medium, absorbent.The above mix refrigerant of binary or binary is the mixture of two or three among R23, R32, the R134a.The solvent that can absorb these cold-producing mediums is dimethyl formamide (DMF) solution.Density is little, and the gas that does not react, is insoluble to absorbent with cold-producing medium, absorbent is hydrogen or helium.
As shown in Figure 2, embodiment 1 adopts R134a (boiling point is-26 ℃) and R23 (boiling point is for-81 ℃), and mixture is as cold-producing medium, and dimethyl formamide (DMF) is an absorbent, and helium is a balanced gas.Driver module 1 is made up of heat energy driver 12, riser 13 and first gas-liquid separator 14 in this scheme, and component separation module 3 is made up of second gas-liquid separator 15 and condenser/evaporator 16 and pipeline.
Present embodiment is made up of three main loops: refrigerant loop, solution loop and balance gas return path.
In refrigerant loop, mix refrigerant is heated effusion in heat energy driver 12, promotes solution simultaneously and promotes in riser 13, enters first gas-liquid separator 14.After the separation through first gas-liquid separator 14, mixed refrigerant vapor enters into be cooled medium cooling of condenser 2, and the part cold-producing medium is condensed into liquid.Then, these gas-liquid mixed refrigerants enter in second gas-liquid separator 15 and separate, gaseous state after the separation partly is mainly lower boiling cold-producing medium R23 and a small amount of high boiling refrigerant R134a, and liquid part is mainly high boiling refrigerant R134a and a small amount of lower boiling cold-producing medium R23.Diffusion back and gaseous refrigerant heat exchange in condenser/evaporator 16 in the balanced gas helium that liquid refrigerant flows out in first flow control valve 5 make liquid refrigerant evaporate the gaseous refrigerant condensation.Spread in the helium that in second flow control valve 6, flows out after the helium that condensed cold-producing medium (key component is R23) flows out with evaporimeter 7 in regenerator 4 and the heat transfer of mixture gas of cold-producing medium, enter evaporimeter 7 evaporation absorption refrigerations.The mist that flows out evaporimeter 7 mixes with the cold-producing medium that is evaporated (key component is R134a) and the mist of helium of outflow in the condenser/evaporator 16 after regenerator 4 heat exchange, then, in heat exchanger 8,, then enter in the gas absorber 9 and absorbed by solution with the balanced gas helium heat exchange of flowing out from liquid reservoir 10 tops.The concentrated solution that has absorbed cold-producing medium flows to the heat energy driver 12 through solution heat exchanger 11 and after the weak solution heat exchange that first gas-liquid separator 14 flows out.
In solution loop, flow back in the gas absorber 9 the absorption refrigeration agent after the concentrated solution heat exchange that the weak solution that flows out flows out from first separator 14 in solution heat exchanger 11 and from liquid reservoir 10.Flow in the heat energy driver 12 behind concentrated solution process liquid reservoir 10 after the absorption, the solution heat exchanger 11.Heating promotes solution from the refrigerant vapour of wherein overflowing and rises, and through riser 13, enters into first gas-liquid separator 14.

Above-mentioned said heat energy driver, condenser, evaporimeter, gas absorber, regenerator, heat exchanger and solution heat exchanger all are heat exchanger, they can be immersion or fountain, can be that shell and tube also can be bushing type or other forms, its heat exchanger tube can be that common tube also can be an enhanced tube.
Riser mainly plays lifting solution, drives the effect of solution circulation, can be the common metal pipe, also can be pressure hose.
Liquid reservoir is similar in liquid reservoir and the common refrigerating plant.
The effect of two flow control valves is amounts of two branch balance gases of control, thus the partial pressure of control diffusion back cold-producing medium, and they can be capillary, automatic or manual valve.
Condenser/evaporator is a heat exchanger, and its high-pressure side is the high vapor phase refrigerant of low boiling content heat release therein cooling and is condensed into liquid that its low-pressure side is that the high gas-liquid two-phase cold-producing medium of higher boiling content evaporates endothermic gasification therein.It can be immersion or fountain, can be that shell and tube also can be bushing type or other forms, and its heat exchanger tube can be that common tube also can be an enhanced tube.
The effect of gas-liquid separator be will enter wherein mixture separate, lower boilingly flow out from its top with gaseous state, high boilingly flow out from its bottom with liquid state.
Because adopted gas-liquid separator in the component separation module, therefore, this embodiment is simple in structure, but cryogenic temperature is low inadequately.
As shown in Figure 3, embodiment 2 adopts R134a (boiling point is-26 ℃) and R23 (boiling point is for-81 ℃), and mixture is as cold-producing medium, and DMF (dimethyl formamide) is an absorbent, and helium is a balanced gas.Driver module 1 is made up of heat energy driver 12, riser 13 and first gas-liquid separator 14 in this scheme, and component separation module 3 is made up of rectifier unit 17 and condenser/evaporator 18 and pipeline.
