Embodiment 1

[0043] Such as figure 1 As shown, the phase change heat storage heat pump water heater according to the embodiment of the present invention includes: a condensing heat exchange tube 12, a compressor 20, a four-way valve 30, an evaporator 40 with a fan 50 attached to it, and a throttling member 60 connected in sequence The heat pump system, and the waterway system formed by sequentially connecting the cold water inlet pipe 90, the water pump 92, the hot water heat exchange pipe 14 and the hot water outlet pipe.

[0044] Wherein, the condensation heat exchange tubes 12 and the hot water heat exchange tubes 14 are alternately arranged in the phase change heat storage tank 10 of the phase change heat storage type heat pump water heater, and the condensation heat exchange tubes 12, the hot water heat exchange tubes 14 and the phase change storage tanks are arranged alternately. The gap between two inner walls of the hot box 10 is filled with phase change heat storage material 16 . ...

Embodiment 2

[0063] Such as figure 2 As shown, according to the control method of the heat pump water heater in the first embodiment of the present invention, considering that the phase change heat storage type heat pump water heater of this solution can not only exchange heat between the condensing heat exchange tube, the phase change heat storage material, and the hot water heat exchange tube, The hot water supply can be realized by heat, and the hot water supply can also be directly heated by the auxiliary heating device installed on the cold water inlet pipe, and the phase change thermal energy storage of the phase change heat storage material occurs during the hot water supply process, then When the phase change heat storage heat pump water heater does not provide hot water to users, the temperature of the phase change heat storage heat pump water heater can be controlled based on the temperature of the phase change heat storage material and the temperature of the environment where th...

Embodiment 3

[0083] Such as Figure 4 As shown, the heat pump water heater control method according to the second embodiment of the present invention, in this embodiment, the auxiliary heating device is an electric heating device, specifically includes the following process steps:

[0084] In step S401, the phase-change thermal storage heat pump water heater receives a power-on signal and enters a standby state.

[0085] Step S402, detecting the current ambient temperature, and judging whether the ambient temperature is greater than Th' (ie, the preset ambient temperature), if not, execute step S403, otherwise, execute step S07.

[0086] In step S403, the phase change heat storage heat pump water heater starts the electric heating heat storage mode.

[0087] Step S404, judging whether the maximum value of the temperature of the phase-change thermal storage material detected by the temperature-sensing packages T1, T2, and T3 (that is, a plurality of temperature detection elements) is less ...

Abstract

The invention provides a phase-change heat-storage heat-pump water heater, a control method and device thereof, and a storage medium. The phase-change heat-storage heat-pump water heater comprises a cold water inlet pipe, a hot water outlet pipe, an evaporator, a compressor, a four-way valve, a phase-change heat-storage box and a throttling component, wherein the evaporator, the compressor, the four-way valve, the phase-change heat-storage box and the throttling component are connected in sequence; a condensation heat-exchange tube and a hot-water heat-exchange tube are alternately arranged inthe phase-change heat-storage box, and the gap between every two of the condensation heat-exchange tube, the hot-water heat-exchange tube and the inner wall of the phase-change heat-storage box is filled with phase-change heat-storage materials; a refrigerant inlet of the condensation heat-exchange tube is sequentially connected with the compressor, the four-way valve, the evaporator and the throttling component through a pipeline and then is connected to a refrigerant outlet of the condensation heat-exchange tube; the two ends of the hot-water heat-exchange tube are separately connected withthe cold-water inlet pipe and the hot-water outlet pipe; and an auxiliary heating device is arranged on the cold water inlet pipe. By adoption of the technical scheme, the requirement of users for hot water can be met, the size and weight of the heat-pump water heater are effectively reduced, and meanwhile, electric energy is saved.

Description

technical field [0001] The present invention relates to the technical field of heating and ventilation equipment, in particular to a washing control method, a washing control device, a computer-readable storage medium and a washing machine. Background technique [0002] At present, most of the wall-mounted heat pump water heaters on the market are water storage type. Specifically, the heat pump system heats the water in the water tank. With the increase of users' demand for domestic hot water, the water storage type wall-mounted heat pump water heaters have volume and weight. conflict with water consumption. For the wall-mounted heat pump water heater: the large volume will take up a lot of bathroom space, and the heat pump water heater unit is heavy and hung on the bathroom wall, which will cause certain safety hazards. Therefore, how to solve the volume and weight problems of the wall-mounted heat pump water heater is particularly important. Contents of the invention ...
