Problems solved by technology

[0003] However, when the indoor ambient temperature is relatively low, the result is that the coil temperature is relatively low. If the preset anti-freeze protection shutdown temperature does not change, it will directly cause the frequent anti-freeze protection shutdown of the air conditioner. The phenomenon corresponding to the shutdown of the anti-freezing protection is that the outdoor compressor frequently starts and stops, which makes it impossible to perform normal cooling operation and achieve the desired cooling effect. At the same time, the outdoor compressor f

Abstract

The invention provides an anti-freezing control method and device. The anti-freezing control method comprises the steps: detecting an indoor ambient temperature and the temperature of a coil pipe in an indoor machine heat exchanger; increasing the rotation speed of an indoor machine direct-current fan from a preset initial wind speed when the indoor ambient temperature is in a first preset temperature range and the temperature of the coil pipe is in a second preset temperature range. According to the method, the frequent starting and stopping of a compressor during anti-freezing control can be reduced; moreover, effectiveness in refrigeration can be realized, the refrigerating effect can be guaranteed, and the service life of the outdoor compressor can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of home appliance manufacturing, in particular to an anti-freezing control method and device. Background technique [0002] Generally, when the air conditioner is in cooling operation, when the temperature of the coil in the heat exchanger of the indoor unit is lower than the preset anti-freeze protection shutdown temperature for a certain period of time, the outdoor compressor will be stopped directly to protect the air conditioner itself. Protect. [0003] However, when the indoor ambient temperature is relatively low, the result is that the coil temperature is relatively low. If the preset anti-freeze protection shutdown temperature does not change, it will directly cause the frequent anti-freeze protection shutdown of the air conditioner. The phenomenon corresponding to the anti-freezing protection shutdown of the outdoor compressor is that the outdoor compressor frequently starts and stops, which makes...
