Abstract

The invention provides an air conditioner and a control method therefor. The control method comprises: obtaining a defrosting historical operation record of the air conditioner, wherein the defrosting historical operation record comprises the defrosting duration of each time of defrosting of the air conditioner; adjusting the defrosting interval time of the air conditioner according to the defrosting historical operation record; after the heating time of the air conditioner reaches the defrosting interval time, measuring the coil pipe temperature of an indoor unit heat exchanger of the air conditioner, and determining whether the air conditioner starts defrosting according to the coil pipe temperature of the indoor unit heat exchanger of the air conditioner, so that the air conditioner can accurately determine whether the air conditioner starts defrosting, and the working performance of the air conditioner is improved.

Description

technical field [0001] The invention relates to air conditioning equipment, in particular to an air conditioner and a control method thereof. Background technique [0002] Frosting of the heat exchanger is an important factor affecting the air conditioning effect of the air conditioner. In the heating mode, the frost on the heat exchanger of the outdoor unit will block the passage between the fins, increase the air flow resistance, increase the thermal resistance of the heat exchanger, reduce the heat exchange efficiency, and also reduce the energy efficiency ratio of the air conditioner, affecting the air conditioner. The heating effect will reduce the user experience. In order to reduce the adverse effects of frost on the air conditioner, the air conditioner needs to start defrosting according to a certain defrosting interval. [0003] Some air conditioners in the prior art have a fixed defrosting interval, and defrosting will start immediately after the defrosting inter...
