Problems solved by technology

For example, in the related art, a method is proposed to control the frequency of the compressor according to the difference between the indoor temperature and the set temperature and the background environmental noise. The operation reduces the noise of the compressor, and the method of reducing the noise by controlling the compressor to operate at a low frequency has been widely adopted. However, the noise generated during the operation of the compressor between low frequency and high frequency has not been resolved, which leads to user experience bad

Abstract

The invention discloses a variable-frequency air conditioner control device and method and a variable-frequency air conditioner. The device comprises a setting module which is used for receiving the frequency adjusting speed and time range inputted by a user, a detecting and judging module which is used for obtaining the current time when the frequency of a compressor needs to be adjusted and judging whether the current time is within the time range or not, and a control module which is used for driving the compressor to increase / decrease the frequency at the frequency adjusting speed inputted by the user when the current time is within the time range, wherein the frequency adjusting speed is smaller than the reference frequency adjusting speed of the variable-frequency air conditioner. By means of the device, noise produced by the air conditioner in the frequency adjusting process is lowered, the requirements of some users sensitive to noise are met, and the interference which is caused by small noise to users in the rest stage particularly at the quiet night is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control device and method for an inverter air conditioner and the inverter air conditioner. Background technique [0002] At present, in order to speed up the cooling and heating speed of the inverter air conditioner, most air conditioner manufacturers adopt the frequency control of the compressor by fast lifting. The rapid rise and fall of the compressor frequency will inevitably increase the noise of the compressor, and will also lead to rapid changes in the pressure of the refrigeration system, increasing the flow noise of the refrigerant in the evaporator of the indoor unit, so for some people who are sensitive to noise, such as For the elderly, it will cause discomfort, especially in the quiet night when people are resting, which is more likely to disturb residents and cause user complaints. [0003] In order to solve the noise problem of the frequency conversion...
