The connecting plate type heat exchanger 16 of refrigerant circuit 11.The pressure differential of the air entry of compressor 12 and exhaust outlet is bigger, then the power of compressor 12
Higher, power consumption is accordingly also bigger.
As well known to those skilled in the art, temperature and the pressure of refrigerant have positive correlation, when refrigerant temperature is relatively low, its
Pressure is relatively low；Pressure of the pressure of the air entry of compressor 12 less than the exhaust outlet of compressor 12.Therefore, when operating mode is not good, pressure
The air entry and exhaust outlet pressure difference of contracting machine 12 are very big, the power rise of compressor 12, more power consumption.
In the present invention, the used heat in absorbing hot blast by making evaporator 15 is improved in heat pump at evaporator 15
Operating mode, improves the pressure of the air entry of compressor 12.The present invention simultaneously by plate type heat exchanger 16, in making plate type heat exchanger 16
Heat efficiently can be absorbed by recirculated water, so as to maintain the relatively low pressure at expulsion of compressor 12.So, using the present invention
Pump type heat hot-water heating drying system, the operating mode at plate type heat exchanger 16 and evaporator 15 is in kilter, compressor 12
The pressure differential of air entry and exhaust outlet is smaller, substantially reduces the actual power of compressor 12, has significantly saved the energy.
The restriction in the directions such as "left", "right" and "front", "rear" in the present invention, only states the relative position of technical characteristic
Put and be conveniently used, not as the specific restriction to structure of the present invention.Those skilled in the art should be understood that each specific part in sky
Between on relation, any rotation, symmetrical etc. can be made on the basis of of the invention and is set, do not influence the normal of function of the present invention
Realize, obviously converted on this direction, and other equivalents for being carried out to technical characteristic in the present invention, all should contain
Cover in the middle of scope of the presently claimed invention.
