Abstract

The invention discloses a heating / air condition / hot water machine, which can simple the cost 40%. The invention couple heating, air condition, hot water system totally, uses air condition heat pump and its circulating pump and heat exchanger 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 t...
