Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to a defrosting control method for an air conditioner. In order to improve defrosting efficiency of the air conditioner, the defrosting control method disclosed by the invention controls the air conditioner with dual fans on an outdoor unit, and the method comprises the following steps: detecting current I-upper of the upper fan and current I-lower of the lower fan; while a first preset value and I-lower is greater than or equal to I-lower / Ie and is smaller than or equal to I-upper / Ie, enabling the air conditioner to enter a defrosting mode; after the air conditioner enters the defrosting mode, controlling the upper fan and the lower fan to stop rotation; after first set time, separately detecting atemperature t-upper of the upper part of an outer coiled tube, a temperature t-middle of the middle part of the outer coiled tube, and a temperature t-lower of the lower part of the outer coiled tube;and selectively controlling the upper fan and the lower fan to reversely rotate or stop rotation according to at least one of t-upper, t-middle and t-lower. The defrosting control method accurately blows off a frost layer by selectively controlling the upper fan and / or the lower fan to reversely rotate according to t-upper, t-middle and t-lower, and greatly improves defrosting efficiency of the air conditioner.

Description

Technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a defrosting control method for an air conditioner. Background technique [0002] As a device that can adjust the indoor ambient temperature, the working principle of the air conditioner is to reduce or increase the indoor ambient temperature through the high-pressure / low-pressure / gas / liquid state conversion of the refrigerant between the circulating pipelines. From the perspective of the indoor unit, the air conditioner is in cooling or heating mode. When the air conditioner is heating, under certain humidity conditions, if the temperature of the outdoor coil is too low, it will cause frosting, and the frosting of the outdoor coil will reduce the heat exchange efficiency of the outdoor heat exchanger, which will affect the air conditioner’s control. Thermal effect reduces the comfort of indoor environment and affects user experience. Therefore, when the air con...
