Abstract

The invention provides an air conditioner and a compressor control method thereof. After the outdoor ambient temperature enters the corresponding outdoor ambient temperature subsection, according to the change of the ambient temperature, the subsection target frequency corresponding to the outdoor ambient temperature subsection is performed. Correction. When the ambient temperature decreases, the load demand becomes smaller, and the target frequency correction decreases to prevent the air conditioner from running at high frequency, and the output of the air conditioner is adjusted in real time to reduce energy, so as to adapt to the changing environment needs; when the ambient temperature increases, the When the load demand increases, the target frequency correction increases, and the output of the air conditioner is adjusted in real time to adapt to the changing environment. The invention can control the operating frequency of the compressor of the air conditioner to change gradually following the change of the ambient temperature, prevent the stepwise change, achieve the purpose of precise control, reduce the fluctuation of the operating frequency of the compressor, improve the use comfort, and improve the energy saving of the air conditioner.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and particularly relates to an air conditioner and a compressor control method thereof. Background technique [0002] The air conditioner achieves the effect of energy saving and comfort by adjusting the operating frequency (speed) of the compressor to control the cooling output. The frequency control of the compressor is one of the core technologies of the air conditioner, which determines the advantages and disadvantages of the air conditioner in terms of stability, comfort and energy saving. [0003] The frequency control method of the existing inverter air conditioner is as follows: [0004] Target frequency segment control method: divide the outdoor ambient temperature into multiple temperature intervals, each temperature interval corresponds to a determined target frequency, and in different temperature intervals, the compressor frequency is always close to the target frequency co...
