Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to a defrosting control method of an air conditioner. In order to prevent the room temperature from fluctuating excessively during defrosting, the defrosting control method of the air conditioner comprises the following steps that whether the air conditioner meets defrosting conditions during the heating operation of the air conditioner or not is judged; if so, the indoor ambient temperature is obtained before the air conditioner enters a defrosting mode; and the indoor ambient temperature and the presettemperature are compared, and the operating frequency of the compressor, an opening degree of the throttle valve or the fan rotation speed of an indoor unit and / or an outdoor unit are selectively controlled according to the comparison result. According to the defrosting control method of the air conditioner, the operating frequency of the compressor, the opening degree of the throttle valve or the fan rotation speed of the indoor unit and / or the outdoor unit are selectively controlled based on the difference between the preset temperature and the indoor ambient temperature to store a part ofthe energy, the part of the energy is replenished to the indoor unit during defrosting of the air conditioner, and the room temperature is effectively prevented from fluctuating excessively during defrosting.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner defrosting control method. Background technique [0002] As a device that can adjust the indoor ambient temperature, the air conditioner works on the principle that the indoor ambient temperature is reduced or increased by the refrigerant passing through the circulation pipeline through high-pressure / low-pressure / gas / liquid state transitions, that is, from From the perspective of the indoor unit, the air conditioner is in cooling or heating mode. When the air conditioner is in heating operation, if the temperature of the outdoor coil is too low under certain humidity conditions, it will cause frosting, and the frosting of the outdoor coil will reduce the heat exchange efficiency of the outdoor heat exchanger and affect the cooling performance of the air conditioner. The thermal effect reduces the comfort of the indoor environment and affec...
