Abstract

The invention provides a window air conditioner and a control method thereof. The window air conditioner comprises an air conditioner shell and an evaporator cavity arranged on the indoor side of theair conditioner shell. The evaporator cavity is provided with an evaporator cavity air inlet and an evaporator cavity air outlet. The evaporator cavity air inlet serves as an indoor side air inlet. The evaporator cavity air outlet communicates an indoor side air outlet flue. The indoor side air outlet glue communicates with an indoor side air outlet. Air supplied by the window air conditioner is conveyed out through the indoor side air outlet. A centrifugal fan is arranged at the evaporator cavity air outlet or on the indoor side air outlet flue. An evaporator is arranged in the evaporator cavity. An air inlet bypass channel is formed between the evaporator cavity air inlet and the indoor side air outlet flue. An air door is arranged in the air inlet bypass channel. After the window air conditioner is started, the frosting and defrosting processes of the evaporator are achieved by controlling air inputting in the air inlet bypass channel so as to achieve self cleaning.

Description

technical field

[0001] The present invention relates to an air conditioner, in particular to a window type air conditioner and a control method thereof. Background technique

[0002] At present, split household air conditioners on the market have the function of evaporator self-cleaning. The principle is brief: when the evaporator needs to be cleaned, the indoor side fan of the split air conditioner stops, while the compressor and the outdoor side fan operate normally, causing the indoor evaporator to be damaged by wind. The side heat exchange efficiency is extremely low, and the evaporation temperature is very low, which is far lower than the saturation temperature corresponding to the humid air under the current pressure, so the moisture in the air will condense on the fins of the indoor evaporator and liquefy. The water on the evaporator will condense into ice. After freezing to a certain extent, through the four-way reversing valve, the exhaust heat of the compressor is...
