Abstract

The invention relates to the technical field of smart homes, and discloses a defrosting control method for an air conditioning system. The method comprises the steps that when the air conditioning system operates in a heating mode, it is determined that the air conditioning system is triggered to enter a defrosting mode, wherein the heating mode comprises that a first refrigerant circulation loop conveys a refrigerant according to the flow direction of a heating refrigerant, the second refrigerant circulation loop is in a conducting state, and the refrigerant flow of the first refrigerant circulation loop is larger than the refrigerant flow of the second refrigerant circulation loop; and the refrigerant flow of the first refrigerant circulation loop is controlled to be smaller than or equal to the refrigerant flow of the second refrigerant circulation loop, so that the air conditioning system operates in a defrosting mode. According to the method provided by the embodiment of the invention, the indoor environment fluctuation is small in the overall operation process of the air conditioning system, the indoor temperature can be maintained within the temperature range comfortable for a user, and the use experience of the user is improved. The invention further discloses a defrosting control device for the air conditioning system and the air conditioning system.

Description

technical field [0001] The present application relates to the field of smart home technology, for example, to a method and device for defrosting control of an air-conditioning system, and an air-conditioning system. Background technique [0002] At present, with the improvement of people's living standards, air-conditioning system equipment has also entered thousands of households. The use of household air-conditioning systems and central air-conditioning systems is becoming more and more common. Users have higher and higher requirements for the comfort of air-conditioning systems. The problems existing in the use of the air-conditioning system are also gradually exposed. One of them is the problem of frosting and freezing of the outdoor unit when the air-conditioning system is running in severe cold weather. When the air conditioning system is operating in a low-temperature area or an area with heavy wind and snow, the heat exchanger of the outdoor unit absorbs heat from th...
