The CO2The second expansion valve is provided on efficient mapper.
The compressor parallel together, CO2Efficient mapper is connected in parallel.
Present apparatus application CO of the present invention2Efficient system is intended for CO2The separation and liquid storage function of vapour-liquid body, have
Two kinds of functions, first progress CO2The gas a part of vapour-liquid body separated is by CO2Compressor air suction suck back and compressed
Machine, fluid storage is in gas-liquid separator lower part by CO2Efficient mapper component sucking sends back to CO2Liquid storage device in be again introduced into
Cooling system circulation.
Liquid, which enters after expansion valve throttling, in liquid storage device is evaporated heat exchange into evaporator, evaporates gas/liquid of completion
The vapour point that body enters intermediate liquid storage function together carries out vapor-liquid separation process.The liquid and partial flash gas quilt separated
CO2Liquid storage device progress system circulation is re-introduced into after carrying out decompression throttling after efficient mapper sucking.The shwoot of another part
Gas enters the cooling condensation cycle of air cooler after carrying out compression work done by compressor sucking.This CO2System will be the following efficient CO2
The maximum direction of operation study, it will be suitable for the refrigeration of environment-friendly natural working medium under the whole nation or global all regions environmental condition
System or heat pump system.Component technology is required greatly to improve.
The design of this gas-liquid separator has multiple outlets such as gas-liquid import, gas outlet and liquid outlet, and there are two types of temperature respectively
Gas or liquid, which enter in this container, enters next stage circuit after progress heat exchange.
There is heat exchange in this process, have the function of this gas-liquid separator to separate liquid the gas of medium temperature
Avoid liquid hammer generation out, but the gas of medium temperature temperature degree after the sub-cooled of cryogenic gas obtain it is further under
Drop, and learnt by refrigeration principle, after the gas of the gas of the medium temperature lower temperature that gas is sucked by compressor after being cooled down,
Reduce the work done of compressor, so that the efficiency of the compressor improved, reduces energy consumption.And the gas that low temperature is returned, due to temperature
Spend it is low more there is gas refrigerant with liquid back to compressor, the possibility of low-temperature level compressor liquid hammer, passes through in order to prevent
This gas/liquid separator device by the gas of low temperature obtained medium temperature grade vapour-liquid body carry out heat temperature raising make low temperature gas or
Person's liquid further vaporizes, and avoids the liquid hit phenomenon generation that liquid returns to compressor.
Beneficial effects of the present invention:
