Abstract

The invention provides a method for controlling the frequency of a frequency converting air conditioner, which comprises the following steps: determining limit frequency; determining temperature controlling frequency; allowing the temperature controlling frequency of the compressor to be an operation frequency, wherein the operation frequency can not exceed the limiting frequency. The method for controlling the frequency of the frequency converting air conditioner controls the running frequency of the air conditioner according to the change rate and a temperature difference value of room temperature, has the characteristics of small change fluctuation of the room temperature, low cost and the like, and gives full play to the energy efficiency of the frequency converting air conditioner and simultaneously protects the safety of electrical appliances effectively.

Description

Technical field [0001] The invention relates to the field of air conditioners, in particular to a frequency control method of a frequency conversion air conditioner. Background technique [0002] The air conditioner is a widely used air conditioning equipment. Its main function is to adjust the temperature and humidity of the air. Compared with ordinary fixed frequency air conditioners, inverter air conditioners have the advantages of energy saving and comfort. The frequency of the DC compressor of the inverter air conditioner is adjustable, see figure 1 The frequency control circuit diagram of an existing inverter air conditioner is shown, which mainly includes an indoor unit 10 and an outdoor unit 20. The indoor unit 10 includes an indoor unit controller 11 and an indoor return air sensor for collecting indoor ambient temperature. 12. Indoor tube temperature sensor 13 for collecting indoor evaporator temperature, outdoor unit 20 includes outdoor unit controller 15, outdoor retu...
