Abstract
An efficient high-temperature air-source storage-type heat pump water heater comprises a compressor, a four-way valve, a water storage tank, a controller, an expansion valve, a condenser, an evaporator and a liquid storage tank. The efficient high-temperature air-source storage-type heat pump water heater further comprises an inner heat exchanger and a regulating valve. The inner heat exchanger comprises a liquid tank, an inner condenser and an inner evaporator. One end of the inner condenser is connected with the condenser inside the water storage tank, and the other end of the inner condenser is connected with the expansion valve. One end of the inner evaporator is connected with the evaporator, and the other end of the inner evaporator is connected with the four-way valve. The regulating valve is connected with the inner evaporator in parallel. The controller controls the regulating valve. Heat exchange quantity of the inner heat exchanger is regulated to keep pressure and temperature of an outlet of the compressor constant by adjusting the opening of the regulating valve. Therefore, work conditions of the compressor are stabilized, the service life of the compressor is prolonged, COP (coefficient of performance) value is increased, the temperature of water in the water storage tank is increased, and utilization rate of the water storage tank is increased.
Description
Technical field
The present invention relates to a kind of Teat pump boiler.
Background technology
Air source water storage type heat pump water heater in the prior art comprises compressor, cross valve, water storage tank, controller, expansion valve, condenser, evaporimeter and fluid reservoir, condenser is arranged in the water storage tank, compressor is connected with cross valve, cross valve is connected with condenser with expansion valve, and condenser is communicated with expansion valve; Expansion valve is connected with evaporimeter, and evaporimeter is communicated with cross valve; Described controller is connected with cross valve with compressor, and controller is connected with the temperature sensor that fluid reservoir, water storage tank and evaporimeter are connected, and the pressure sensor of the pipeline between controller and cross valve and the compressor is connected with temperature sensor.Coolant-temperature gage in the water heater water storage tank can only reach at most 60 ℃; and in the whole service process; the operating mode of compressor is extremely unstable; along with the temperature of the water in the water heater water storage tank constantly raises, the pressure of compressor outlet and temperature also constantly raise, the increase of output power of compressor; if continuing like this operation goes down; compress meeting high pressure or overtemperature protection and left alone without help machine, the loss to compressor is very large like this, shortens the service life of compressor.Because the water storage temperature is low, then the utilization rate of water storage tank is also low.
Summary of the invention
The objective of the invention is: a kind of efficient, temperature air-source water storage type heat pump water heater is provided, it can make the coolant-temperature gage of water heater water storage tank bring up to the same with the temperature of compressor outlet working medium, the operating mode of compressor is stable, prolong the service life of compressor, improve the COP value, play energy-conserving action.
The present invention is achieved in that a kind of efficient, temperature air-source water storage type heat pump water heater, comprise compressor, cross valve, water storage tank, controller, expansion valve, condenser, evaporimeter and fluid reservoir, condenser is arranged in the water storage tank, compressor is connected with cross valve, cross valve is connected with condenser with expansion valve, and condenser is communicated with expansion valve; Expansion valve is connected with evaporimeter, and evaporimeter is communicated with cross valve; Its special character is: also comprise internal exchanger and a control valve, described internal exchanger comprises fluid box, inner condenser and interior evaporimeter;
Condenser in described inner condenser one end and the water storage tank is connected, the other end and Peng are expanded, and valve is connected; Described interior evaporimeter one end is connected with evaporimeter, the other end is connected with cross valve;
Described control valve is in parallel with interior evaporimeter; Described controller control and regulation valve.
A kind of efficient, temperature air-source water storage type heat pump water heater of the present invention owing in adopting such structure, by the aperture of control valve, regulate the heat exchange amount of internal exchanger, keeps the pressure and temperature of compressor outlet constant; Thereby reach the operating mode of constant compression machine, prolong the service life of compressor, improve the COP value, improve the temperature of water in the water storage tank, improve the utilization rate of water storage tank.
Description of drawings
Fig. 1 is line frame graph of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of efficient, temperature air-source water storage type heat pump water heater, comprise compressor 1, cross valve 2, water storage tank 3, controller 4, expansion valve 5, condenser 6, evaporimeter 7 and fluid reservoir 8, condenser 6 is arranged in the water storage tank 3, compressor 1 is connected with cross valve 2, cross valve 2 and expansion valve 5 are connected with condenser and are connected, and condenser 6 is communicated with expansion valve 5; Expansion valve 5 is connected with evaporimeter 7, and evaporimeter 7 is communicated with cross valve 2; Fluid reservoir 8 and cross valve 2 are connected with compressor and are connected.
Also comprise internal exchanger 9 and a control valve 10, described internal exchanger 91 comprises fluid box 91, inner condenser 92 and interior evaporimeter 93; Cold-producing medium R22 is arranged in the fluid box 91.
Described control valve 10 is in parallel with interior evaporimeter 93.
Described controller 4 and compressor 1 are connected with cross valve and are connected;
Pressure sensor on the pipeline between controller 4 and cross valve 2 and the compressor 1 is connected with temperature sensor; Described controller 4 and fluid reservoir 8, evaporimeter 7 are connected with temperature sensor on water storage tank is connected.
Described controller 4 control and regulation valves 01 arrange stepper motor at control valve 10, and stepper motor drives control valve 10, and controller 4 is connected with stepper motor.
When the temperature in the fluid reservoir 8 was low, together, stepper motor rotated under the effect of controller 4, and the aperture of control valve 10 diminishes, and improves the heat exchange amount of internal exchanger;
When the temperature in the fluid reservoir 8 was high, together, the aperture of control valve 10 increased under the effect of controller 4, reduces the heat exchange amount of internal exchanger;
Above-described only is preferential embodiment of the present invention.Should be pointed out that for the person of ordinary skill of the art in the situation that does not break away from the principle of the invention, can also make some improvement and modification, this also is considered as protection scope of the present invention.
