Abstract

The invention discloses a heat-pump water heater and an electric heating control method, device and system thereof. The method includes: detecting whether current water temperature of a water tank of the heat-pump water heater is greater than a preset threshold; if not, calculating a difference between the current water temperature and first water temperature which is water temperature of the water tank in a preset time before the current time; according to the difference, controlling electric heating for the water tank. The problem that the prior heat-pump water heater using electricity is low in heating speed is solved, and the water temperature of the water tank is quickly increased to the set temperature.

Description

technical field [0001] The invention relates to the field of water heater control, in particular to a heat pump water heater and its electric heating control method, device and system. Background technique [0002] Heat pump water heaters, especially air source water heaters, have become a hot topic in the hot water industry. However, most heat pump water heaters in the prior art have certain problems. One of the problems is that the outlet water temperature cannot be too high (generally the highest outlet water temperature is only 55°C), and the other problem is that the heating speed is slow when the ambient temperature is low. In order to solve these two problems, the water tank distribution heating method is generally adopted in the industry. Specifically, the existing electric heating control method is to turn on the electric heating after the water temperature is higher than a certain temperature (the temperature is between 50 and 60). Using this control method, the ...
