Abstract
The utility model discloses a heat pump water heater comprising a compressor, a condenser, a restricting element, a evaporator and a refrigerant pipeline connecting all the parts. The condenser is a liquid heat exchanger one side of which is connected to the refrigerant pipeline and the other side is connected to a water inlet pipe and a water outlet pipe. The other ends of the two pipes are respectively connected to the upper and lower part of a circulating water tank with an adjustable flow pump installed on the water inlet pipe. The utility model can regulate the water flow from the water inlet pipe by the regulating pump, characterized in a simple structure, an avoided cooling medium leakage and a lower fault rate.
Description
Technical field
The utility model relates to water heater, particularly a kind of water heater that adds hot water with heat pump.
Technical background
Heat pump water heater is because of its energy-saving and environmental protection are with a wide range of applications.Existing heat pump water heater, as Fig. 1, include by compressor 1a, condenser 2a, restricting element 3a, evaporimeter 4a, and water inlet pipe 5a and the outlet pipe 6a composition of the refrigerant pipeline that connects them heat pump, cyclic water tank 7a, communication loop water tank and the condenser 3a that enough become, flow control valve 8a and water pump 9a are housed on its water inlet pipe 5a.The bellows 13a of flow control valve 8a is communicated with the blast pipe 11a of compressor, and spool 12a two ends promote it by bellows 13a and spring 14a and open greatly and turn down, as Fig. 2.When the coolant-temperature gage that flows into condenser 2a raise, the pressure at expulsion of compressor 1a raise, and bellows 13a promotes valve core 12a and opens greatly, makes control valve 8a flow bigger; When the coolant-temperature gage that flows into condenser 2a reduced, the pressure at expulsion of compressor 1a reduced, and spring 14a promotes valve core and turns down, and control valve 8a flow is diminished.It regulates the flow of condenser 2a by flow control valve 8a, and water pump 9a power is constant all the time, can be according to Flow-rate adjustment, thereby power dissipation is big.Simultaneously, the moving component of flow control valve 8a bears the high pressure of refrigerant for a long time, damages easily, needs often to change the fault rate height.In addition, bellows 13a is communicated with in compressor air-discharging pipeline 11a, the continuous stretching motion of bellows, and refrigerant more easily leaks in it, whole heat pump can't run well, water heater can't normally use and make.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, difficult leakage of refrigerant, and the low heat pump water heater of fault rate.
Heat pump water heater of the present utility model, include compressor, condenser, restricting element, evaporimeter, and their refrigerant pipeline of connection, condenser is a liquid heat-exchanger, the one side connects the refrigerant pipeline, opposite side connects water inlet pipe and outlet pipe, and the other end of outlet pipe and water inlet pipe is connected with the upper and lower part of cyclic water tank respectively, and the pump of adjustable water saving flow is installed on the described water inlet pipe.
Heat pump water heater of the present utility model has the pump of adjustable water saving flow on the water inlet pipe, can directly regulate flow of inlet water by regulating pump.When inflow temperature is higher, regulate the running of pump, discharge is strengthened; And inflow temperature then can be regulated the running of pump when low, and discharge is reduced.It only regulates discharge by pump, does not need to use baroque flow control valve, thereby simple in structure; Simultaneously, do not have flow control valve, also just do not need refrigerant is fed the bellows of control valve, refrigerant also just is difficult for leaking; In addition, do not have flow control valve, just do not have the problem of flow control valve damage and replacing, thereby fault rate is low yet.

The specific embodiment
Embodiment 1, as Fig. 3, a kind of heat pump water heater, include compressor 1, condenser 2, restricting element 3, evaporimeter 4, and connect their refrigerant pipeline, condenser 2 is a liquid heat-exchanger, one side of liquid heat-exchanger connects the refrigerant pipeline, the opposite side pipeline connects water inlet pipe 5 and outlet pipe 6, and the other end of outlet pipe 6 and water inlet pipe 5 is connected with the upper and lower part of cyclic water tank 7 respectively, and the pump 8 of the adjustable water saving flow of installing on the water inlet pipe 5 is a variable frequency pump.
On the water inlet pipe 5 variable frequency pump is arranged, directly regulate the rotating speed of variable frequency pump, can regulate discharge.Its Flow-rate adjustment is convenient, simple in structure; Simultaneously, the flow control valve that does not have bellows to be communicated with the compressor air-discharging pipeline, refrigerant are difficult for leaking, the problem that does not exist flow control valve to damage and change, and fault rate is low.
General water heater, when its cyclic water tank 7 was open tank, the feed pipe 13 of water tank was connected with a plurality of water pipes 14, dress booster pump 15 on it.When the usage quantity of water pipe 14 increased or reduces, its pressure of supply water can change, and the water of water pipe 14 has sometimes hot and sometimes cold sensation, and is more uncomfortable.In order to prevent the generation of above-mentioned phenomenon, as Fig. 4, cyclic water tank 7 can use press-bearing water tank, the water tank integral sealing, and the bottom is communicated with water inlet pipe 5 and feed pipe 16, and top connects outlet pipe 6 and feed pipe 13.Because the water tank integral sealing, its pressure of supply water is constant, and when water pipe 14 usage quantities changed, its pressure of supply water was constant, and water outlet can be not sometimes hot and sometimes cold, and is more comfortable.
Can be provided with the dividing plate 9 that water tank is not exclusively separated in the water tank 7, cold water and hot water mixed and stir when it can prevent into water.Simultaneously, because proportion, the water of different temperatures can be understood AUTOMATIC ZONING in water tank, from top to down, temperature has dividing plate 9 from high to low in the water tank, dividing plate 9 can separating high temperature and low temperature, can better prevent the mixing of hot and cold water, thereby, the water that variable frequency pump can be only lower with bottom temp heat exchange in the suction condenser once more, it can guarantee the high temperature difference of refrigerant and water, heat exchange better effects if, the thermal efficiency are also higher.
The pump 8 of adjustable water saving flow also can be the adjustable DC water pump of voltage on the water inlet pipe 5, by regulating the voltage of DC water pump, the rotating speed of adjustable water saving pump, thereby the discharge of regulating water inlet pipe.
The pump 8 of adjustable water saving flow also can be the water pump of a plurality of parallel connections, as Fig. 4, and by the quantity of control pump working, thus the discharge of regulating water inlet pipe 5.
In order to solve evaporimeter 4, the problem of frosting in winter, can one hot-gas bypass pipe 12 be installed at the gas exhaust piping 10 of compressor 1 and 11 of the entrance pipes of evaporimeter, when evaporimeter frosting, hot-gas bypass pipe 12 is opened, the high temperature refrigerant that compressor 1 is discharged directly by in bypass pipe 12 inflow evaporators 4, thereby is eliminated the frost of being tied on the evaporimeter 4.
