The specific embodiment
As shown in Figure 1, the described a kind of energy-saving heat pump formula water heater of the utility model embodiment, comprise housing 1, the inside of described housing 1 is provided with evaporimeter 2 and compressor 3, evaporimeter 2 is provided with fan 4, evaporimeter 2 and fan 4 are formed air cooling heat exchanger, condenser directly is placed on the inside of domestic hot-water's case, utilize the condensation heat of cold-producing medium to heat the domestic hot-water, the outlet of evaporimeter 2 is connected with a port of gas-liquid separator 5 by pipeline, the another port of gas-liquid separator 5 is connected by the air entry of pipeline with compressor 3, the exhaust outlet of compressor 3 is connected with condenser inlet 6 by pipeline, the import of described evaporimeter 2 is connected with a port of electric expansion valve 7 by pipeline, electric expansion valve 7 can automatically switch according to air cooling heat exchanger intake air temperature, the another port of electric expansion valve 7 is connected by the outlet of pipeline with filter 8, the import of filter 8 is connected with condensator outlet 9 by pipeline, thereby form the closed circulation path of cold-producing medium, described fan 4 is connected with controller 10 outputs by circuit with compressor 3, and the input of controller 10 connects hot water temperature's sensor 11 respectively by circuit, EAT sensor 12 and compressor exhaust temperature sensor 13.
During concrete the use, compressor 3 adopts totally-enclosed rotary compressor suction side to be provided with gas-liquid separator 5 and produces Wet Compression to prevent compressor.Throttling arrangement adopts electric expansion valve 7, can under the effect of controller 10, regulate the different open degree of electric expansion valve 7 according to the difference in season.The upper end of electric expansion valve 7 is provided with filter 8, causes the obstruction of pipeline with the impurity of avoiding cold-producing medium.Air cooling heat exchanger is made up of evaporimeter 2 and fan 4, and evaporimeter 2 is the fin tube type structure.Controller 10 as input, is used to control the automatic start-stop of compressor 3 with hot water temperature's sensor 11 and EAT sensor 12, compressor exhaust temperature sensor 13.Electric expansion valve 7 all switches different open degree automatically.The air quantity of air cooling heat exchanger is regulated automatically.The user can establish the hot water serviceability temperature arbitrarily by controller in 30～60 ℃ of scopes; in order to prevent the frequent start-stop of compressor 3; controller 3 will generate the machine that an opens temperature that is lower than 5 ℃ of design temperatures automatically; when hot water temperature in the water tank is lower than this temperature; controller 3 starts compressor automatically; when the hot water temperature reaches design temperature, compressor 3 autostops.When the air cooling heat exchanger EAT is lower than a certain design temperature (as 15 ℃), electric expansion valve 7 is under the effect of controller, automatically switch, regulate less open degree, and when EAT is lower than this temperature, electric expansion valve 7 is adjusted to bigger open degree, and the internal circulating load of cold-producing medium and evaporimeter 2 heat absorption capacities are complementary, and has guaranteed that air source hot pump water heater all has Energy Efficiency Ratio preferably at various weather conditions.
The cyclic process of cold-producing medium is as follows: the liquid refrigerant after electric expansion valve 7 throttlings flows in the evaporimeter 2, under the effect of fan 4, carry out heat convection with outdoor air, absorb airborne heat and evaporate, flow into through gas-liquid separator 5 then and enter in the condenser after compressor 3 is compressed, from then on condensation is discharged to getting water in the storage tank, condensed refrigerant liquid is finished once circulation thus through in filter 8, the electric expansion valve 7 inflow evaporator 2 pipes again.
