Abstract

The invention belongs to the technical field of air conditioners, and specifically relates to a defrosting control method for an air conditioner. In order to increase the defrosting efficiency for theair conditioner, the defrosting control method for the air conditioner aims at the air conditioner with an outdoor unit which is provided with double fans. The method comprises the following steps ofafter the air conditioner enters a defrosting mode, controlling an upper fan and a lower fan to stop rotation; after a first set time, if I(lower) is not less than 1.1Ie and not greater than 1.2Ie, and I(upper) is greater than Ie and less than 1.1Ie, only controlling the upper fan to reversely rotate for a second set time; after the first set time is past, if I(lower) is greater than I(upper) andless than 1.1Ie, and I(upper) is greater than Ie, controlling the lower fan to reversely rotate for the second set time, and controlling the upper fan to reversely rotate for a third set time; and after the first set time is past, if I(lower) is greater than I(upper) and less than 1.1Ie, and I(upper) is equal to Ie, only controlling the lower fan to reversely rotate for the second set time. According to the defrosting control method for the air conditioner, the upper fan and / or the lower fan are / is selectively controlled to reversely rotate according to the I(upper) and the I(lower), and thena frost layer is accurately blown off, so that the defrosting efficiency for the air conditioner is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner defrosting control method. Background technique [0002] As a device that can adjust the indoor ambient temperature, the air conditioner works on the principle that the indoor ambient temperature is reduced or increased by the refrigerant passing through the circulation pipeline through high-pressure / low-pressure / gas / liquid state transitions, that is, from From the perspective of the indoor unit, the air conditioner is in cooling or heating mode. When the air conditioner is in heating operation, if the temperature of the outdoor coil is too low under certain humidity conditions, it will cause frosting, and the frosting of the outdoor coil will reduce the heat exchange efficiency of the outdoor heat exchanger and affect the cooling performance of the air conditioner. The thermal effect reduces the comfort of the indoor environment and affec...
