Embodiment Construction

[0033] Working principle of the present invention is described as follows in conjunction with accompanying drawing 1:

[0034] 1. Air-water heat pump heating cycle: Start compressor 1 to drive refrigerant to flow through high-pressure switch 2, four-way reversing valve 3, muffler 9, evaporator / condenser 8 refrigerant side, check valve 5, dry filter 6. Electronic expansion valve 7, check valve 5, two-way solenoid valve 24, air evaporation / condenser 4, four-way reversing valve 3, gas-liquid separator 10, low-pressure switch 11, compressor 1, forming an air-water heat pump Circulation; to pump the low-level air heat energy collected in the air evaporator / condenser 4 to the evaporator / condenser 8. The circulation pump 13 is started in advance to drive the brine to flow through the check valve 14, the brine side of the evaporator / condenser 8, the exhaust valve 19, the function tee 25, the fan coil 15, the filter 20, and the three-way valve Group 12 and circulation pump 13 form a h...

Abstract

The invention discloses a The invention discloses a heating / air condition / hot water machine, which can simple the cost 40%. It has five optimizing functions including refrigeration / heat pump-air condition + hot water circulation, gas-water hot pump hot water circulation, gas-water hot pump heating circulation, the second grade heat pump heating / hot water circulation, water-water hot pump heating circulation, it produces hot water by little difference in temperature and direct heat changing method; electronic expanding valve changing flux regulation make producing heat attenuation rate at -7 deg.C be improved from 62% to 75%; decreases heating, hot water circulation temperature upper limit, to achieve heat pump producing heat under -7deg.C; uses the water inlet and accordant junction triple valve to achieve water inlet and level pressure behind pump, in order to save pressure reducing valve, flux switch, expansion tank, and make the highest pressure point be less then water inlet pressure, and improve the reliability of the system.

Description

(1) Technical field [0001] The invention relates to a heating / air conditioning + hot water machine. (2) Background technology [0002] The published Chinese invention patent "Secondary Water Ring Composite Heat Pump Driven Heating, Air Conditioning and Hot Water System" (patent application number: 02104844.4) is composed of a "hu"-shaped water system connected to a composite heat pump circuit; the three energy sources complement each other through solar air, electric heating , realize the comprehensive utilization of three functions of heating, air conditioning and hot water; heat transfer / heat storage are combined into one to omit the heat exchange link, the heat / work loss of defrosting is small, the heating heat capacity loss is 0.5%, and the average heating coefficient of the system is increased by 18%; 4 An optimized operation technology to make it run throughout the year; optimize the heat storage temperature and the pressure ratio of the two-stage heat pump to adapt to...
