But most air source hot pump water heaters of domestic production at present and sale all design and process according to winter condition.When these Teat pump boilers move under transition season and summer condition, cold-producing medium evaporating temperature (pressure) can raise and raise along with outside air temperature, if employing capillary, the pressure reduction at two ends capillaceous reduces thereupon, because length capillaceous is fixed, make the refrigerant mass fluxes that flows into evaporator with heat pump reduce, the damp and hot degree of compressor air suction increases, yet influence the volumetric efficiency and the electric efficiency of compressor, even cause the compressor can't operate as normal.This shows, capillary pipe length by the winter condition design can not satisfy whole year operation operating mode needs fully, make that not only the average of the whole year heating performance system of air source hot pump water heater is difficult to improve, but to producing safety, stable operation and actual life of compressor harmful effect.
The utility model content
The purpose of this utility model provides a kind of energy-saving heat pump formula water heater, solves heat pump water heater capacity regulating problem in whole year operation, improves the seasonal energy efficiency ratio (seer) (EER) and the economic performance of heat pump.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of energy-saving heat pump formula water heater, comprise housing, the inside of described housing is provided with evaporimeter and compressor, evaporimeter is provided with fan, the outlet of evaporimeter is connected with a port of gas-liquid separator by pipeline, the another port of gas-liquid separator is connected with the air entry of compressor by pipeline, the exhaust outlet of compressor is connected with condenser inlet by pipeline, the import of described evaporimeter is connected with a port of electric expansion valve by pipeline, the another port of electric expansion valve is connected with the outlet of filter by pipeline, the import of filter is connected with condensator outlet by pipeline, described fan is connected with controller output end by circuit with compressor, and the input of controller connects hot water temperature's sensor respectively by circuit, EAT sensor and compressor exhaust temperature sensor.
The beneficial effects of the utility model are: effectively solved system matches and capacity regulating problem in the Teat pump boiler whole year operation, the heat pump Energy Efficiency Ratio and the systematic economy performance of annual operation have been improved, have energy-efficient, cheap, safe and reliable, long service life, simple operation and other advantages, have good promotion and application prospect.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described energy-saving heat pump formula of the utility model embodiment water heater.
Among the figure:
1, housing; 2, evaporimeter; 3, compressor; 4, fan; 5, gas-liquid separator; 6, condenser inlet; 7, electric expansion valve; 8, filter; 9, condensator outlet; 10, controller; 11, hot water temperature's sensor; 12, EAT sensor; 13, compressor exhaust temperature sensor.
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.
