Air energy water heater and heating control method and device thereof

Abstract

The invention discloses an air energy water heater and a heating control method and device thereof. The method comprises the following steps that the outdoor environment temperature of each time point in the future preset time period is calculated; the heating time period corresponding to the optimal heating energy efficiency value of the air energy water heater is calculated; the water usage amount of a user in the future preset time period is predicted; the set temperature is adjusted according to the water usage amount of the user in the future preset time period; and heating control is conducted on the air energy water heater according to the set temperature at the heating time period corresponding to the optimal heating energy efficiency value, and heating control is conducted over the air energy water heater according to the adjusted set temperature at the water utilization time period. By means of the method, the water utilizing habit of the user can be intelligently analyzed, and therefore the air energy water heater can be controlled to conduct heating in advance at the time period with the highest energy efficiency, and heat losses of the idle time period are reduced; and the heating temperature of the air energy water heater can be intelligently adjusted according to the water usage amount of the user, energy is saved, and meanwhile the water utilizing requirement of the user can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a heating control method for an air-energy water heater, a heating control device for an air-energy water heater, and an air-energy water heater. Background technique [0002] At present, the heating methods of air energy water heaters on the market mainly include: scheduled heating, instant heating, and instant heating. [0003] Because these heating methods cannot be combined with the user's water habits, when the air-energy water heater works in the scheduled heating mode, if there is an emergency water situation, the water temperature in the water tank may not reach the set temperature, resulting in a decrease in the amount of hot water. Insufficient output occurs, which affects the user's water experience; and when the air source water heater works in the instant heating or instant heating mode, because the water temperature in the water tank is at the highest w...

[0003] Because these heating methods cannot be combined with the user's water habits, when the air-energy water heater works in the scheduled heating mode, if there is an emergency water situation, the water temperature in the water tank may not reach the set temperature, resulting in a decrease in the amount of hot water. Insufficient output occurs, which affects the user's water experience; and when the air source water heater works in the instant heating or instant heating mode, because the water temperature in the water tank is at the highest water temperature for a long time, when the user does not use hot water , the heat loss is large, and the compressor is also frequently started and stopped, which affects the service life of the compressor
