Abstract

The invention provides a control method of a heat pump system. The heat pump system comprises a control device and a first temperature detecting device for detecting the real-time temperature of an outdoor heat exchanger of the heat pump system; and whether the delayed defrosting action is executed is judged by the control device according to the relation between the dew-point temperature Td of the environment where the outdoor heat exchanger is located and the real-time temperature T, detected by the first temperature detecting device, of the outdoor heat exchanger. The invention further provides the heat pump system controlled with the method and an air conditioner comprising the heat pump system. The heat pump system is controlled with the control method during heating operation of theheat pump system in winter, whether the delayed defrosting action is executed can be judged by the aid of the dew-point temperature and the real-time temperature of the outdoor heat exchanger, thus the time when the defrosting mode of the heat pump system is enabled can be delayed, then the defrosting frequency can be reduced effectively, the heating energy efficiency of the heat pump system can be improved, and the use comfort level for a user can be increased.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to a control method for a heat pump system, a heat pump system and an air conditioner. Background technique [0002] In recent years, consumers' requirements for quality of life have been continuously improved, and the demand for high energy efficiency of air-conditioning products has been increasing. However, when the existing heat pump system operates in winter, especially in the environment of high humidity in winter such as southern my country, the outdoor unit of the heat pump system is very prone to frost. In this case, in order to avoid the impact of frost on the operation of the outdoor unit, it is necessary to defrost the outdoor unit. When the heat pump system is defrosted, the energy efficiency of the heat pump system will be reduced, thereby reducing the heating effect of the heat pump system. [0003] Most of the defrosting control methods of the existing heat pump ...
