Abstract

The invention discloses an air energy water heater control method and an air energy water heater. The water heater is provided with a dehumidification program, and the control method comprises the following steps that S1, judging that the environment where the water heater is located is in the state that bathing is finished; S2, a dehumidification program of the water heater is started, and the environment where the water heater is located is dehumidified; and S3, the difference value between the evaporation temperature Tev of an evaporator and the dew point temperature TL in the environment is calculated, and operation parameters of a water heater fan and an electronic expansion valve are adjusted according to a calculation result. After it is detected that a user finishes bathing, an automatic control unit starts and operates the dehumidification program, high-temperature and high-humidity air in the environment where the water heater is located enters the evaporator through the fan to be cooled and dehumidified, the difference value between the evaporation temperature of the evaporator and the environment dew point temperature is calculated, the operation parameters of a heat pump water heater fan and the electronic expansion valve are optimized, and rapid dehumidification and energy conservation can be achieved.

Description

technical field [0001] The invention belongs to the field of water heaters, and in particular relates to an air energy water heater control method and the air energy water heater. Background technique [0002] For integral air energy heat pump water heaters, especially wall-mounted integral air energy heat pump water heaters, they are often installed in toilets or bathrooms. After the user takes a bath, the air temperature in the bathroom is high and the humidity is high. For the high-temperature and high-humidity air treatment plan after bathing in the bathroom, the hot and humid air is mainly discharged through exhaust fans, or through natural convection by opening windows. [0003] The Chinese patent application number 200910070896.X discloses an indoor integral wall-mounted dehumidification heat pump water heater, which includes a hot water tank and an equipment tank divided into two parts by a partition. The hot water tank is provided with an outlet pipe, an inlet pipe...
