Abstract

The invention provides a defrosting control method and device for an air source heat pump system and an air conditioning system. The defrosting control method for the air source heat pump system comprises the steps that the environment temperature, the fin temperature, the fan running current and the duration time are selected to serve as parameter conditions for starting defrosting together; andthe fin temperature or defrosting operation time is selected to serve as a parameter condition for finishing defrosting. According to the defrosting control method of the air source heat pump system,defrosting of the air source heat pump system is accurate and timely.

Description

technical field [0001] The invention belongs to the technical field of heat pumps, and in particular relates to a defrosting control method, device and air conditioning system of an air source heat pump system. Background technique [0002] During the heating process of the air source heat pump system, when the outside temperature is low, frost is easy to form on the outdoor heat exchanger, which reduces the heat exchange effect of the outdoor heat exchanger, thus affecting the heating process of the air source heat pump system. When the frosting reaches a certain level, the indoor heating effect is low, and even the indoor heat exchanger cannot be heated, that is, the heating air that is higher than the indoor temperature cannot be blown out. At this time, it is necessary to remove the frost on the outdoor heat exchanger to restore its heat exchange effect and ensure the heating performance of the air source heat pump system. [0003] However, the defrosting control method...
