Further, the expansion valve uses heating power expansion valve or electric expansion valve.
Further, the evaporator is copper pipe aluminum fin heat exchanger or micro-channel parallel flow heat exchanger.
Since using the above structure, the utility model by overheated gas forecooler, use by the condensed water that evaporator is generated
In the pre-cooling of compressor outlet refrigerant, to reduce the temperature that refrigerant enters condenser, the negative of condenser is reduced in this way
Lotus, is conducive to the even running of system, while improving the refrigerating efficiency of system.
In conclusion the utility model added overheated gas forecooler in the compressor outlet, only replace a small amount of
Exhaust pipe, do not destroy the original structure of system, it is easy for construction, operation operation and maintenance it is simple, operating cost is lower, investment
Few, payoff period is short.On the basis of the present apparatus guarantees that each component of air-conditioning system is stable, using condensed water cooling capacity, by system
Cooling capacity carry out inner utilization.
