Abstract

The invention discloses an air conditioner and a control method thereof. The control method of the air conditioner comprises the following steps of determining a frequency change value of a compressoraccording to a first compressor frequency before the compressor runs for a first preset time and a second compressor frequency after the compressor runs for the first preset time; determining an exhaust temperature difference value according to an actual exhaust temperature of the compressor; according to the frequency change value and the exhaust temperature difference value, determining an opening degree adjusting value of an electronic expansion valve, and the opening degree adjusting value = proportionality coefficient * the exhaust temperature difference value + integral coefficient * exhaust temperature difference value change integral value + the frequency change value * frequency change coefficient * outdoor environment temperature coefficient; and obtaining a target opening valueof the electronic expansion valve according to the opening adjustment value. According to the air conditioner control method, the response speed of the opening degree of the electronic expansion valve is high, the problems of refrigerant flowing noise, exhaust temperature fluctuation and the like of the air conditioner can be avoided, and the use comfort of a user is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method thereof. Background technique [0002] In related technologies, the response speed of the electronic expansion valve opening of the air conditioner is relatively slow, which leads to obvious problems such as refrigerant flow noise and exhaust temperature fluctuations in the air conditioner. On the one hand, it will affect the energy efficiency of the air conditioner. , will reduce user comfort. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a control method for an air conditioner, so that the response speed of the opening of the electronic expansion valve is faster, thereby avoiding problems such as refrigerant flow noise and exhaust temperature fluctuation, and improving user expe...
