Water tank target water temperature control method and air source heat pump water heater

Abstract

The invention discloses a water tank target water temperature control method and an air source heat pump type water heater applying the method. The water tank target water temperature control method comprises the following steps that water demands and water temperatures at different times are set; the water tank target water temperature is worked out according to the volume of a water tank and thewater using time; and the section where the worked-out water tank target water temperature is located is judged, and the final water tank target water temperature is determined. According to the water tank target water temperature control method and the air source heat pump type water heater, fuzzy evaluation of the water supply temperature of the water tank is carried out according to the simulated water supply volume and the water temperature of user water, it can be guaranteed that the water supply temperature of the water tank is reduced as much as possible under the situation that the user water heat is enough, and the air source heat pump energy consumption is reduced.

Description

technical field [0001] The invention relates to household appliances, in particular to a method for controlling the target water temperature of a water tank and an air source heat pump water heater. Background technique [0002] Water heaters are common household appliances. The usage habit of most users is to set a fixed temperature, and the temperature sensing package of the water tank detects that the water reaches the set temperature value to keep warm. Due to the different water habits of users and the different purposes of water (such as washing dishes, bathing, washing vegetables, washing face, etc.), the required outlet water temperature is also different. The energy consumption of the air source heat pump is closely related to the set water temperature, and the higher the set water temperature of the water tank, the higher the energy consumption will be. Since the water heater is mixed with tap water to meet the actual water temperature requirements of the user, a...

[0003] Box temperature to achieve energy saving is not realistic in actual use

[0004] In addition, the energy-saving function of conventional air source heat pump water heaters is within the operating range of the heat pump, and the auxiliary electric heating is not turned on.

When the user uses a large amount of water, the water temperature will drop, resulting in poor user experience
