Condensing heat exchanger 51 is arranged in the weather side of heat exchanger 60; Heat water and heat under the while operational mode; Heat exchanger 60 plays the evaporimeter effect; Outdoor air is earlier through behind the condensing heat exchanger 51, improved the air themperature of heat exchanger 60 of flowing through, improved the evaporating temperature and the heat exchange effect of heat exchanger 60 simultaneously, makes unit can under lower environment temperature, heat water and heating operation.
The 4th: high temperature heats water and refrigeration while operational mode;
As shown in Figure 4; High temperature heats water, and the concrete operational mode of operational mode is following simultaneously with refrigeration: cross valve 16 outages; Magnetic valve 3 52, magnetic valve 4 53 must be established by cable logical, and condensing heat exchanger 51 condensation is again crossed in 24 condensations of HTHP gaseous coolant superheated water generator; To reservoir 45, the liquid refrigerants that flows out from reservoir 45 flow to refrigerant pipe 1 through refrigerant pipe 4 47 through refrigerant pipe 5 48
,The indoor apparatus of air conditioner 3 that entering has refrigeration to require; Through magnetic valve 2 39, check valve 3 38, restricting element 2 36, entering indoor units 35 sweat coolings; Cross refrigerant pipe 2 41, magnetic valve 4 53, cross valve 16 then, return compressor compresses afterwards, constitute a circulation.
Another road HTHP cold media gas that compressor 9 is discharged is crossed cross valve 16, magnetic valve 3 52, to heat exchanger 60 condensations, crosses check valve 4 50,
WarpRefrigerant pipe 3 46 is to reservoir 45, reservoir 45 in, with above-mentioned one tunnel refrigerant liquid mixing, constitutes and circulates.
Under the hot environment, can give magnetic valve 5 63 energisings, open magnetic valve 5 63,, reduce the compressor air suction temperature, satisfy the demand of high temperature refrigeration to compressor 9 suction end hydrojet attitude refrigerants.
The 5th: low-temperature heating water with heat operational mode simultaneously.
As shown in Figure 5: low-temperature heating water with heat that simultaneously the concrete operational mode of operational mode is following: cross valve 16 energisings; Magnetic valve 3 52, magnetic valve 4 53 must be established by cable logical; The HTHP cold media gas is crossed cross valve 16, magnetic valve 4 53, is crossed refrigerant pipe 2 41; Entering has the indoor apparatus of air conditioner 3 of the requirement of heating, in indoor units 35 condensations heat radiation, afterwards through check valve 2 37, magnetic valve 2 39, refrigerant pipe 1
,To reservoir 45, the liquid refrigerants that flows out from reservoir 45 flows through electric expansion valve 44, gets into heat exchanger 60 evaporations through refrigerant pipe 3 46, crosses magnetic valve 3 52, cross valve 16 then, returns compressor compresses afterwards, constitutes a circulation through refrigerant pipe 4 47.
Another road HTHP cold media gas that compressor 9 is discharged cross high pressure refrigerant pipe 1, refrigerant be connected valve 2 22 with water heater, in hot water generator 24 condensations; Cross condensing heat exchanger 51 condensation again; Flow to reservoir 45 through refrigerant pipe 5 48; In reservoir 45,, constitute circulation with above-mentioned one tunnel refrigerant liquid mixing.
Under the low temperature environment, can give magnetic valve 6 65 energisings, open magnetic valve 6 65,, improve the compressor air suction temperature, satisfy the demand of low-temperature heating to compressor air suction end spray high-temperature gas refrigerant.
Condensing heat exchanger 51 of the present invention plays the effect of condenser; Because the high temperature and high pressure gas refrigerant temperature that compressor 9 is discharged is up to more than 80 ℃; After the high temperature and high pressure gas refrigerant is through the hot water generator condensation; The water temperature of hot water generator 24 is reached more than 55 ℃, and the high temperature and high pressure gas refrigerant still has about 50 ℃ through hot water generator 24 condensed temperature, but become liquid condition; If this high temperature, high pressure liquid refrigerant directly gets into reservoir 45, be not favourable for getting into heat exchanger 60 evaporations; If the water temperature of hot water generator 24 has reached more than 55 ℃, do not need to heat again, the 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 getting into heat exchanger 60 evaporations; Configuration condensing heat exchanger 51; No matter the high temperature and high pressure gas refrigerant is in whether fully condensation of hot water generator, it can both be condensed into liquid condition with the high temperature and high pressure gas refrigerant, if the 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; Just make refrigerant cold excessively, it is very favourable that refrigerant is crossed the 60 evaporation heat absorptions of cold back heat exchanging device, and refrigerating capacity can be improved to indoor units 35 refrigeration in
.Condensing heat exchanger 51 is side-by-side with heat exchanger 60; When need add hot water and indoor heating winter; Refrigerant temperature owing to flow through in the condensing heat exchanger 51 is about 50 ℃, and outdoor air is earlier through condensing heat exchanger 51, with the refrigerant heating in the heat exchanger 51 that is condensed; Just pass through heat exchanger 60 (heat exchanger 60 need absorb heat when evaporimeter uses during winter heating) then from outdoor air.Such as: when temperature outside winter reaches-15 ℃; Outdoor air just might be heated to-5 ℃ or higher temperature through condensing heat exchanger 51 backs earlier; Just improved EAT during again through heat exchanger 60; EAT improves the also corresponding raising of evaporating temperature of back heat exchanger 60, and the heating efficiency of whole air-conditioning unit and Energy Efficiency Ratio are improved.
The high temperature and high pressure gas refrigerant that the inventive method makes full use of the compressor discharge comes heat hot water; Utilize its waste heat to improve the evaporating temperature and the heat exchange efficiency of heat exchanger 60 then again; The used heat that air conditioner is produced has used ultimate attainment, and the efficient of air conditioner has also been brought up to ultimate attainment.
The above-mentioned listed specific embodiment is nonrestrictive; As heat the water unit merely; Can not want the element such as cross valve, magnetic valve 3 52, magnetic valve 4 53 of indoor apparatus of air conditioner and air-conditioner outdoor unit, can reach the effect that efficiently heats water equally, and can more heat water under the low temperature; Therefore, to one skilled in the art, do not departing from the scope of the invention, various improvement and the variation carried out all belong to protection scope of the present invention.
