Problems solved by technology

[0004] However, since the heating capacity of the heat pump host may change after running for a period of time, and the ambient temperature may also change during the operation, a simple calculation will produce a large deviation, which will cause the electric auxiliary heater to be turned on in advance, making the power consumption It may also cause the electric auxiliary heater to delay opening, so that the water temperature of the heat pump hot water unit cannot reach the set temperature

Abstract

The invention discloses a heat pump water heater unit and its control method and device. The method includes the following steps: after receiving the valley electricity signal, obtaining the water temperature of the water tank; if the water temperature is lower than the set temperature, controlling the heat pump host to Open state; every first preset time, calculate the time required for the water temperature of the water tank to rise to the first preset temperature when the heat pump main unit and the electric auxiliary heater are turned on at the same time, and record it as the first time; if the first time is less than the second The preset time controls the electric auxiliary heater to be on. The method controls the opening of the electric auxiliary heater according to the time required for each increase of the preset temperature of the water tank when the heat pump main unit and the electric auxiliary heater are simultaneously turned on in real time, so as to not only achieve the purpose of energy saving, but also meet the needs of users. water temperature needs.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a control method of a heat pump water heater, a control device of the heat pump water heater and a heat pump water heater with the device. Background technique [0002] In the peak and valley electricity consumption, although the price of the valley electricity is very cheap, the total time of the valley electricity is limited. In order to use the heat pump host as much as possible within a limited time, and at the same time ensure that the water temperature of the heat pump hot water unit reaches the set temperature, it is necessary to control the electric auxiliary heater to turn on at an appropriate time. [0003] In related technologies, the opening of the electric auxiliary heater is controlled according to the preset water temperature, that is, when the water temperature of the heat pump water heater unit reaches the preset water temperature, the electric auxil...
