Abstract

The invention relates to the technical field of air conditioner control, and specifically discloses a control method for air-conditioner defrosting. The control method comprises the following steps: obtaining operation parameters of an air-conditioning unit, wherein the operation parameters of the air-conditioning unit comprise an outdoor temperature of the air-conditioning unit, a fin temperatureof the air-conditioning unit, a compressor pipeline pressure value of the air-conditioning unit and an outer coiled tube temperature of the air-conditioning unit; judging whether the air-conditioningunit meets a defrosting condition or not according to the operation parameters of the air-conditioning unit; when the air-conditioning unit meets the defrosting condition, controlling to start an air-conditioner defrosting function; judging whether the air-conditioning unit meets an air-conditioner defrosting exit condition or not according to operation parameters of the air-conditioning unit; and while the air-conditioning unit meets a defrosting exit condition, controlling the air-conditioning unit to stop the air-conditioner defrosting function. The invention further discloses a control device and a control system for air-conditioner defrosting. The control method for air-conditioner defrosting provided by the invention can effectively realize automatic defrosting of the air conditioner.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control, in particular to an air conditioner defrost control method, an air conditioner defrost control device and an air conditioner defrost control system including the air conditioner defrost control device. Background technique [0002] As we all know, the working principle of the air conditioner when heating is the opposite state when cooling, that is, the air conditioner releases heat to the indoor and cools the outdoor, and the heat exchanger (finned tube) of the outdoor unit cools at a lower temperature than the environment, absorbing the surrounding The heat energy contained in the air is released to the indoor air through the heat exchanger of the indoor unit to achieve the purpose of heating the indoor environment. The heat exchanger of the outdoor unit will cause the moisture contained in the passing air to frost on its surface due to cooling (heat absorption). After wo...
