Abstract

The present application discloses an air conditioner and its anti-condensation method and device. The method includes the following steps: obtaining the current input voltage of the air conditioner; recognizing that the air conditioner has entered a low-voltage operating state according to the current input voltage; Limit the operating frequency of the compressor in the air conditioner. The anti-condensation method of the present application can effectively solve the problem of water blowing and dripping from the indoor heat exchanger when the input voltage is low, and improve the reliability of the operation of the air conditioner.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to an air conditioner and its anti-condensation method and device. Background technique [0002] At present, the minimum operating voltage of the inverter air conditioner can reach 150V, the wind speed of the indoor fan is relatively high, and the evaporation temperature is relatively high. The condensation water generated can flow away through the water tray of the internal unit, so there is no risk of condensation. [0003] In the related technology, the minimum operating voltage of the inverter air conditioner can reach 40V, or even lower. The lower the voltage, the lower the speed of the indoor fan. At the same frequency, the temperature of the evaporator will be greatly reduced, and the evaporator will have serious condensation, resulting in air conditioner failure. Water blowing and dripping from the air conditioner will affect the reliability of the air con...
