Further, second solenoid valve is provided with the pipeline between three-limb tube and condenser.
Further, the 4th magnetic valve and the second electric expansion valve are provided with the pipeline between condenser and economizer.
Further, flowed between fluid reservoir and evaporator provided with the first electric expansion valve and cooling matchmaker towards evaporator
3rd check valve.
Further, the first check valve is set in the outlet of solar absorber plate, set in the import of solar absorber plate
3rd electric expansion valve.
Further, the outlet of the economizer passes through pipeline connection with compressor inlet.Carry out the high pressure liquid of condenser
State refrigerant is divided into two parts after economizer is entered, and a part is further cooled down by throttling in a manner of heat expands,
The temperature of reduction another part is gone, makes its supercooling, this subcooled liquid settled out directly enters evaporator system by fluid reservoir
It is cold.And the uncooled gaseous coolant of another part reenters compressor continuation by economizer and the connecting pipe of compressor
Compression, into circulation.Stablize liquid refrigerants by way of swell refrigeration, to improve power system capacity and efficiency.
Compared with prior art, this direct expanding solar heating pump system has advantages below：
1. when sunny, flowed using solar absorber plate in assisted heat pump system
Refrigerant evaporation, improve evaporation efficiency；
, can automatic defrosting at low temperature 2. have defrost circulation line；
3. having capillary, a part of refrigerant can be returned to gas under less than -20 DEG C environment
Liquid/gas separator, the suction temperature of compressor is improved, increase inspiratory capacity, reduce compression
Machine high-low pressure ratio is poor, and system is more stable, more efficient, protects compressor, prevents
Compressor is scrapped because live load is too big.
