Mostly present existing air source hot pump water heater is to be made up of parts such as compressor, condensing heat exchanger, blower fan, evaporimeter, throttling arrangement and intelligence control systems, it is the heat by the working medium absorption chamber outer air in the blower fan evaporimeter, compressed machine compression back is discharged into the heat that is absorbed in the water by another heat exchanger, confesses domestic hot-water more than 50 ℃ to the user.Its overall economic efficiency is higher, and the environmental protection and energy saving benefit is good especially, because the Teat pump boiler self characteristics, is installed in outdoorly mostly, thereby can produce following problem:
Outdoor climate altered a great deal in 1 year, and China's north and south local climate difference is bigger, made the regulating working conditions of air source heat pump complicated.When environment temperature was low, along with the decline of temperature, the operational efficiency of air source hot pump water heater also sharply descended; In addition, in the higher place of relative humidity,, be 5 ℃ as ambient air temperature even when environment temperature is not too low, the condenser of outdoor and air heat exchange will frosting in heat transfer process, thereby influences outdoor heat exchanger and heat exchange efficiency air; And when environment temperature is higher than 30 ℃; rising along with temperature; the air-breathing of compressor also constantly raises, and the thermal efficiency of air source hot pump water heater then sharply descends, and the operating pressure of working medium is constantly soaring; this moment, compressor had to start high voltage protective; stop compressor operating, and this moment, the water in the water heater did not also reach setting value, compressor need restart again; so not only reduced the thermal efficiency of air source hot pump water heater repeatedly, and to the life-span grievous injury of compressor.So when environment temperature more than 35 ℃ or when being lower than below-12 ℃, the air source hot pump water heater cisco unity malfunction.
Characteristic according to present compressor and working medium just determined, do not have a kind of air source hot pump water heater can adapt to worst hot case about 40 ℃, can adapt to the worst cold case about-12 ℃ again.At above problem, can design a kind ofly can will become problem demanding prompt solution at normally operation, low, the safe and reliable air source hot pump water heater of cost that can normally move again under the worst hot case more than 40 ℃ under the worst cold case below-12 ℃.
Summary of the invention:
For addressing the above problem, the present invention constructs and has invented a kind of air source hot pump water heater capable of changing speed and regulating pressure under multiple working conditions and hot water unit.That is: utilize the adjustable characteristic of speed-changing draught fan or blower fan group, thereby the suction temperature of regulating compressor by the evaporation capacity that Based Intelligent Control is regulated evaporimeter easily with the operating mode range expansion of air source hot pump water heater to-16 ℃-50 ℃, having guaranteed that air source hot pump water heater can adapt to can both operate as normal under the various working.
The technical scheme that key technical problem adopted that the present invention solves is:
The evaporation capacity of evaporimeter mainly determined by disengagement area and air face velocity, if change a certain value wherein, will change the evaporation capacity of evaporimeter.In actual use, the malleable not in case disengagement area of evaporimeter is determined, regulate the air face velocity of evaporimeter so utilize the adjustable characteristic of speed-changing draught fan or blower fan group, thereby reach the purpose of regulating the evaporator evaporation amount, when regulating evaporation capacity, also regulated the suction temperature of compressor and the operating pressure of delivery temperature and working medium;
Specifically: when environment temperature constantly rises, the suction temperature of compressor also increases, reduce the rotating speed of blower fan or blower fan group this moment, then can reduce the evaporation capacity of evaporimeter, make suction temperature not raise and to raise along with environment temperature again, thereby guaranteed the required suction temperature of compressor operate as normal.And when environment temperature constantly reduces, the suction temperature of compressor also decreases, and improve the rotating speed of blower fan or blower fan group this moment, then can improve the evaporation capacity of evaporimeter, make suction temperature not reduce and to reduce along with environment temperature again, thereby guaranteed the required suction temperature of compressor operate as normal.
Implementation method; Under standard condition, evaporator with heat pump speed-changing draught fan or the operation of blower fan group middling speed; When environment temperature was lower than the standard condition temperature, speed-changing draught fan or blower fan group high-speed cruising can improve the evaporation capacity of evaporimeter, were used for compensating because environment temperature is crossed the low suction temperature that causes crosses low and to the influence of compressor; And when environment temperature was higher than the standard condition temperature, speed-changing draught fan or blower fan group be low cruise then, just can reduce the evaporation capacity of evaporimeter, was used for compensating for because the too high suction temperature that causes of environment temperature is too high to the influence of compressor;
