Problems solved by technology

Solar water heaters use natural energy and have the characteristics of saving energy, but their heating effect is greatly affected by the weather; gas water heaters and electric water heaters have better rapid heating effects, but their energy waste is serious, which does not meet the national energy conservation and emission reduction guidelines
Traditional heat pump water heaters are driven by electric energy and use air heat sources to heat water, which has the advantage of saving energy, but it has disadvantages such as poor rapid heating effect, large floor space, and easy breeding of bacteria in the water tank.

Embodiment 1

[0051] like figure 1 As shown, Embodiment 1 of the present invention provides a heat pump water heater system, which includes a compressor 100 , a throttling component, a first heat exchanger 200 , a second heat exchanger 300 and a first energy storage device 400 . The compressor 100 is provided with an intake port 102 and an exhaust port 104, an intake air temperature sensor Th and a low pressure switch K1 are provided at the intake port 102, and a gas-liquid separator 502 and a low pressure tank 504 are also connected at the intake port 102, The exhaust port 104 is provided with an exhaust temperature sensor Tp, a high pressure switch K2 and a high pressure sensor P; the throttling component can be as follows figure 1 The electronic expansion valve EXV (Electronic Expansion Valve) shown can also be a capillary tube; the first heat exchanger 200 is connected between the air inlet 102 and the electronic expansion valve EXV, and the first heat exchanger 200 can be a fin heat ex...

Embodiment 2

[0072] like image 3 As shown, the second embodiment of the present invention provides a heat pump water heater system. On the basis of the first embodiment, a four-way valve 700 and a second energy storage device 800 are added. The first end s of the four-way valve 700 is connected to the intake port 102 , the second end d of the four-way valve 700 is connected to the exhaust port 104 , and the third end c of the four-way valve 700 is connected to the first heat exchanger 200 away from the electronic expansion valve One end of EXV, the fourth end e of the four-way valve 700 is connected to one end of the first refrigerant pipeline 302 away from the electronic expansion valve EXV; the second energy storage device 800 is connected in parallel with the first refrigerant pipeline 302 and is connected to the first energy storage device 400 Similarly, the second energy storage device 800 can also be a phase change energy storage device filled with phase change material, and the num...

Embodiment 3

[0093] like Figure 5 As shown, the third embodiment of the present invention provides a heat pump water heater system. On the basis of the first embodiment, an electromagnetic heating module 900 is added, which is specifically arranged on the extension pipe of the second water inlet pipe 404, that is, the second water inlet pipe. The water outlet trunk road after the road 404 and the water outlet pipeline 600 converge. The electromagnetic heating module 900 can provide heat by means of electricity, and can cooperate with the first energy storage device 400 to provide a better rapid heating effect for the system when the heat stored by the first energy storage device 400 is insufficient. It can be understood that the heat pump water heater system without the electromagnetic heating module 900 is specifically used in the environment south of the Yangtze River, and the heat pump water heater system equipped with the electromagnetic heating module 900 is specifically used in the ...

Abstract

The invention provides a heat-pump water heater system which comprises a compressor, a throttling component, a first heat exchanger, a second heat exchanger and a first energy storage device, whereinthe compressor is provided with an air inlet and an air outlet; the first heat exchanger is connected between the air inlet and the throttling component; the second heat exchanger is provided with a first refrigerant pipeline and a first water inlet pipeline; the first refrigerant pipeline is connected between the air outlet and the throttling component; the first energy storage device is providedwith a second water inlet pipeline; and the second water inlet pipeline is connected in series to an air outlet end of the first water inlet pipeline. According to the heat-pump water heater system provided by the embodiment of the invention, by combining the second heat exchanger with the first energy storing device, twice heating of waterflow can be realized, and the quick heating effect is improved, and at the moment, a water tank of the traditional heat-pump water heater can be cancelled, so that when energy consumption is reduced, the development cost is reduced, the occupied area of theheat-pump water heater system is reduced, and bacteria breeding is reduced.

Description

technical field [0001] The present invention relates to the technical field of air-conditioning manufacturing, in particular to a heat pump water heater system. Background technique [0002] At present, the water heaters on the market mainly include four types of solar water heaters, gas water heaters, electric water heaters and heat pump water heaters. Solar water heaters use natural energy and have the characteristics of energy saving, but their heating effect is greatly affected by the weather; gas water heaters and electric water heaters have better rapid heating effects, but their energy waste is serious, which does not meet the national energy conservation and emission reduction guidelines. The traditional heat pump water heater is driven by electric energy and uses the air heat source to heat the water, which has the advantage of saving energy, but it has the disadvantages of poor rapid heating effect, large floor space, and easy breeding of bacteria in the water tank...
