Embodiment 1

[0029] The compressor frequency control method of the inverter air conditioner of the present embodiment includes the following steps:

[0030] ①. When the compression is not started, calculate the target frequency of compressor operation according to the difference between the current indoor ambient temperature and the set temperature. The calculation formula is:

[0031] F o b j e c t l = F H Λ Λ ( Δ T m ≥ 3 ) { ( ...

Abstract

The invention discloses a frequency control method of a compressor of a variable frequency air conditioner. The method includes the following steps that (1) before the compressor is started, the target operating frequency of the compressor is worked out according to the difference of the current indoor environment temperature and the set temperature; (2) two minutes later after the compressor is started, the target operating frequency of the compressor is regulated according to the difference of the current indoor environment temperature and the set temperature; (3) after the compressor operates for two minutes, the difference of the current indoor environment temperature and the set temperature is compared once every two minutes, the refrigerating or heating effect of the air conditioner is judged according to changes of the difference of the current indoor environment temperature and the set temperature, and when the temperature difference is kept constant or is increased, the current operating frequency of the compressor is compensated. A more linear control mode is provided for the current operating mode of the compressor based on the use demands of users and the operating characteristics of the variable frequency compressor, use experience of the users is improved, and the operating range of the compressor is expanded.

Description

technical field [0001] The invention relates to a compressor frequency control method of an inverter air conditioner. Background technique [0002] Inverter air conditioners are increasingly popular in our daily life. Faced with the existence of a large number of inverters on the market, the compressor frequency control methods are also different, and the user experience is also different. With the improvement of end users' use experience, the requirements for inverter compressor control are also increasing. The timeliness of the compressor frequency control method of the existing inverter air conditioner is poor, and the adjustment range is not linear enough. Contents of the invention [0003] The purpose of the present invention is to provide a compressor frequency control method of an inverter air conditioner with a more timely adjustment and a more linear adjustment range, so as to improve user experience and increase the operating range of the compressor. [0004] T...
