Abstract

The invention discloses a control method and device for an air conditioner, which belong to the technical field of the air conditioners. The control method comprises determining a frosting condition of an indoor unit when the air conditioner is operated in a refrigeration mode; and when the indoor unit is frosted under the refrigeration mode, controlling and blocking a cold medium pipeline flowing to the indoor unit. The control method for the air conditioner controls and blocks the cold medium pipeline flowing to a heat exchanger having a frosting problem, a low temperature cold medium is stopped from being continuously conveyed into the heat exchanger which has been deforested, the frosting problem is prevented from being further aggravated, and besides, the temperature of an environment where the heat exchanger is can be used to defrost and deice the heat exchanger naturally to realize a freezing protection action on the heat exchanger of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and device. Background technique [0002] During the operation of the existing air conditioner products, the indoor unit and the outdoor unit of the air conditioner often have freezing problems under different working conditions. For example, when the air conditioner is running in cooling mode in summer, if the set cooling temperature and the actual indoor and outdoor ambient temperatures are too low, and the speed of the indoor fan is low, the temperature of the inner coil will be too low, causing the indoor The heat exchanger will freeze and freeze; or, when the air conditioner operates in the heating mode in winter, when the set heating temperature and the actual indoor and outdoor ambient temperature are low, the temperature of the outer coil itself It will also be too low, causing the outdoor heat exchanger of the outdoor unit to f...
