Abstract

The invention discloses an inverter compressor operating frequency adjusting method, comprising the following steps: when detecting that an inverter air conditioner is in a heating mode, acquiring the target operating current of an inverter compressor; adjusting the operating frequency of the inverter compressor according to the target operating current; acquiring continuous operating time, present operating frequency and operating frequency before a first pre-set period of time of the inverter compressor; when judging that the continuous operating time is greater than or equal to a second pre-set period of time and the present operating frequency is greater than or equal to the operating frequency before the first pre-set period of time, acquiring maximum operating frequency of the inverter compressor within a third pre-set period of time; acquiring current correction according to the maximum operating frequency, and correcting the target operating current according to the current correction. The inverter compressor operating frequency adjusting method can be used for automatically adjusting the operating frequency of the inverter compressor when indoor and outdoor machines are not communicated with each other. The invention also discloses an inverter compressor operating frequency adjusting device and an inverter air conditioner system comprising the same.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and in particular to a method for adjusting the operating frequency of a variable frequency compressor, a device for adjusting the operating frequency of a variable frequency compressor, and an inverter air conditioning system including the device for adjusting the operating frequency of the variable frequency compressor. Background technique [0002] With the continuous development of air conditioning technology, DC inverter air conditioners are becoming more and more popular in the market, and their sales are also increasing rapidly. At present, the frequency conversion air conditioners on the market all need to be installed together, and the indoor unit and the outdoor unit need special supporting communication methods to realize the control of the compressor of the outdoor unit. Therefore, the installation of indoor and outdoor units must be synchronized and matched. [0003] The st...
