Abstract

The invention discloses a control method and device used for an air conditioner and capable of modifying defrosting conditions. The control method includes the steps that the content of particulate matters in a target environment is detected, and the target environment is the environment where a heat exchanger of an air conditioning unit is located; and when the content of the particulate mattersin the target environment is higher than the preset content, the defrosting control conditions of the air conditioning unit are modified, and the defrosting control conditions of the air conditioningunit are temperature conditions to control the air conditioning unit to execute defrosting. Through the control method and the control device, the problem that in correlation techniques, particulate matters in the air are attached to a heat exchanger and affect the heat exchange effect, as a result, the unit misjudges defrosting conditions and carries out defrosting frequently is solved.

Description

technical field [0001] The present application relates to the technical field of air conditioner control, in particular, to an air conditioner control method and device with corrected defrosting conditions. Background technique [0002] When the air conditioner is in the heating mode, the unit judges whether defrosting is required by detecting the defrosting temperature collected by the temperature sensor on the outer surface of the heat exchange tube of the heat exchanger. Specifically, with the heating running time, the detected defrosting temperature Decrease gradually. When the collected defrost temperature is lower than the normal defrost temperature, the unit will judge by default that there is a lot of frost on the heat exchanger at this time, and defrost control is required. [0003] Since the heat exchanger is composed of densely distributed fins and copper tubes, the gaps between the densely distributed fins are very small, and the rotation of the fan drives the ai...
