Abstract:
A method and apparatus for defrosting control of an air-conditioning system, and an air-conditioning system. The method comprises: when an air-conditioning system operates in a heating mode, determining to trigger the air-conditioning system to enter a defrosting mode, wherein the heating mode comprises a first refrigerant circulation loop delivering a refrigerant according to a heating refrigerant flow direction, a second refrigerant circulation loop being in a turned-on state, and a refrigerant flow of the first refrigerant circulation loop being greater than a refrigerant flow of the second refrigerant circulation loop; and controlling the refrigerant flow of the first refrigerant circulation loop to be less than or equal to the refrigerant flow of the second refrigerant circulation loop, such that the air-conditioning system operates in the defrosting mode. By means of the method, the fluctuation in the indoor environment is relatively small during the overall operation process of the air-conditioning system, and the indoor temperature can be kept within a comfortable temperature range for a user, thereby improving the usage experience of the user.
