The refrigerant gas of high temperature and pressure out provides power for refrigeration cycle.To realize compression → condensation (heat release) → expansion → steaming
Send out the refrigeration cycle of (heat absorption)
Ammonium hydroxide thermal diffusion-absorption refrigeration (pool Lai Deng-Meng Taer system):
This system needs hot end to heat, absorption refrigeration using the water of naturally occurring and ammonia etc. as refrigerant, to environment and
Atmosphere is harmless；Using thermal energy as drive energy, other than it can use steam, fuel thermal energy, can also using waste heat, waste heat,
The low grade heat energies such as solar energy, mostly heat exchanger, quiet operation are with small vibration；Meanwhile refrigeration machine is transported under vacuum conditions
Row, structure is simple, securely and reliably, easy for installation.Coolant liquid absorbs heat evaporation in evaporator, is formed by steam and is absorbed
Agent is absorbed, and after this, the absorbent for absorbing refrigerant vapour is pumped to generator by solution, is added in generator
Heat, and refrigerant vapour is isolated, which is condensed into liquid within the condenser, then enters evaporator after throttling.
Compressor refrigeration is that one end is cold end, and the other end is hot end, and hot end is needed with a large amount of radiator (condenser)
To radiate, it is ensured that system stable operation.The waste heat generated in this way is discharged into air, a large amount of this refrigeration equipment discharge heat
Gas will cause thermal pollution, and radiator needs to use the electric motor fan of relatively high power, can also cause the noise of motor operation dirty
Dye.
Ammonium hydroxide thermal diffusion-absorption refrigeration, opposite pollution is few very much, and when refrigeration needs heat source, needs to increase heat concentration in this way
Equipment, in some instances it may even be possible to need to burn coal etc. mode to heat, be likely to result in pollution or need external more resources and equipment
Waste.
Summary of the invention
In order to energy saving, reduction energy loss, and equipment is more minimized, the object of the present invention is to provide small-sized appearances
Product formula compressor and ammonium hydroxide absorb combined refrigeration system, and the combined refrigeration system is by ammonia water absorbing refrigerator system and positive displacement
Compressor refrigeration system is combined together, and the heat generated using positive displacement compressor refrigeration system is to ammonia water absorbing refrigerator
Ammonia spirit in system is heated, and cold end refrigerating capacity is superimposed by compressor refrigeration and ammonium hydroxide absorption refrigeration, and presses
Contracting mechanism cold is without heat extraction and heat will efficiently use, to reach the feelings of bigger refrigerating capacity or identical refrigerating capacity
Condition declines low-power consumption, and reduces the noise pollution of thermal pollution and radiating motor fan.Signified small-sized positive displacement in the present invention
Compressor refers to that power consumption is less than the compressor of 2.2KW.
The purpose of the present invention is a kind of Small-Volumed Compressor and ammonium hydroxide absorb joint refrigeration by the following technical programs
System, wherein positive displacement compressor refrigeration system includes compressor, condenser, evaporator and expansion valve, one end of condenser with

Exchanger and throttle valve are connect with absorber, it is characterised in that: the positive displacement compressor refrigeration system and ammonia water absorbing system
Cold system is connected by thermal conductivity system；The heat that the thermal conductivity system generates condenser and compressor is to the ammonia in generator
Aqueous solution is heated.
Condenser and compressor are given out a large amount of heat and are used directly to heat ammonia spirit by the present invention, condensation
The heat-dissipating pipe of device is the heater in generator, in this way, not only saving energy, and reduces the pollution to environment.
Thermal conductivity system of the invention is by the condenser of positive displacement compressor refrigeration system and compressor in compressed gas process
The heat of middle generation removes the generator in heating ammonia water absorbing refrigerator system, so that ammonia water absorbing refrigerator be made to work.
Compared with prior art, the energy that the present invention need to only drive positive displacement compressor to work can allow ammonia water absorbing refrigerator same
When work, it is superimposed that cold end refrigerating capacity by compressor refrigeration and ammonium hydroxide absorbs refrigeration, and compression mechanism cold is not necessarily to heat extraction
And heat will efficiently use, to reduce power consumption in the case where reaching bigger refrigerating capacity or identical refrigerating capacity, and subtract
Few thermal pollution and the noise pollution of radiating motor fan.
