Under low temperature environment, can give magnetic valve 6 65 energisings, open magnetic valve 6 65, to compressor air suction end spray high-temperature gas refrigerant, improve compressor air suction temperature, meet the demand of low-temperature heating.
Condensing heat exchanger 51 of the present invention plays the effect of condenser, the high temperature and high pressure gas refrigerant temperature of discharging due to compressor 9 is up to more than 80 ℃, when high temperature and high pressure gas refrigerant is after hot water generator condensation, can make the water temperature of hot water generator 24 reach more than 55 ℃, and high temperature and high pressure gas refrigerant still has 50 ℃ of left and right through the condensed temperature of hot water generator 24, but become liquid condition, if this high temperature high pressure liquid refrigerant directly enters reservoir 45, be not favourable for entering heat exchanger 60 evaporations; If the water temperature of hot water generator 24 has reached more than 55 ℃, do not need to heat again, high temperature and high pressure gas refrigerant just can not get abundant condensation in hot water generator 24 so, becomes gas-liquid mixture, is comparatively disadvantageous to entering heat exchanger 60 evaporations; Configuration condensing heat exchanger 51, no matter high temperature and high pressure gas refrigerant is in the whether abundant condensation of hot water generator, it can be condensed into liquid condition by high temperature and high pressure gas refrigerant, if high temperature and high pressure gas refrigerant has been condensed into liquid in hot water generator, condensing heat exchanger 51 has just played condensation again, namely make refrigerant excessively cold, it is very favourable that refrigerant is crossed cold rear heat exchanger 60 evaporation endothermics
can improve refrigerating capacity to indoor units 35 refrigeration.condensing heat exchanger 51 and heat exchanger 60 are side-by-side, in the time that need heating water and indoor heating winter, because the refrigerant temperature of flowing through in condensing heat exchanger 51 is 50 ℃ of left and right, outdoor air first passes through condensing heat exchanger 51, by the refrigerant heating being condensed in heat exchanger 51, then during just through heat exchanger 60(winter heating, heat exchanger 60, when evaporimeter uses, need to absorb heat from outdoor air).Such as: in the time that temperature outside winter reaches-15 ℃, outdoor air is first just likely heated to-5 ℃ or higher temperature after condensing heat exchanger 51, during again through heat exchanger 60, just improve EAT, the also corresponding raising of evaporating temperature of heat exchanger 60 after EAT improves, improves the heating efficiency of whole air-conditioning unit and Energy Efficiency Ratio.
The high temperature and high pressure gas refrigerant that the inventive method makes full use of compressor discharge carrys out heat hot water, then utilize again its waste heat to improve evaporating temperature and the heat exchange efficiency of heat exchanger 60, the used heat that air conditioner is produced has used ultimate attainment, and the efficiency of air conditioner has also been brought up to ultimate attainment.
The above-mentioned listed specific embodiment is nonrestrictive, as simple water heating unit, the elements such as the cross valve, magnetic valve 3 52, magnetic valve 4 53 of indoor apparatus of air conditioner and air-conditioner outdoor unit can be do not wanted, the effect of efficient water heating can be reached equally, and can be at water heating under lower temperature; Therefore, to one skilled in the art, not departing from the scope of the invention, the various modifications and variations of carrying out, all belong to protection scope of the present invention.
