1, need a water/hydro-thermal pump or a boiler+cooling tower, go to drive a group water/air heat pump operation, system's initial cost is big;
2, indoor water/air heat pump noise is big, installation is inconvenient, troublesome maintenance.
The twin-stage or the cascade type heat pump that constitute by cold-producing medium circulation, the compression ratio of every compressor all can be controlled in 2.5～3.5, so compressor isentropic efficiency and volumetric efficiency height, restriction loss is little, the unit mass refrigerating capacity is big, compressor exhaust temperature is low, cross little, the heat pump heat supply coefficient height of heat loss.Yet there is following point in this system in actual motion:
1, need two compressors and 3～4 refrigerant heat exchanger, system's initial cost increases;
2, the control of refrigerant line and system is complicated;
3, can't realize three energy complementations of solar-air electric heating and heating, air conditioning, and water heating functions three function synthesized utilizations;
4, system only adapts to low temperature environment, is difficult to use in spring and autumn and summer.
The objective of the invention is to want the advantage of prior aries such as comprehensive secondary heat pump, water-loop heat pump, combined heat-pump, improve its weak point, a kind of coefficient of heat supply is higher, the environmental adaptation scope is bigger, the thermal capacitance loss of heat hot water the is littler secondary water ring combined heat-pump and the heating, air conditioning, and water heating functions system of driving thereof are provided.
