Abstract

The invention discloses a variable frequency air conditioner and a control method thereof. The control method comprises the steps that when the variable frequency air conditioner is started, firstly,various system protection is detected, when a system detects that the shutdown protection condition is met, the current operation frequency F1 is memorized, and then shutdown treatment is conducted; after shutdown treatment, whether the protection quitting condition is met or not is judged, and if the protection quitting condition is met, the frequency is calculated again and increased for operation; if the protection quitting condition is not met, various system protection is detected again; when the protection quitting condition is met and the frequency is calculated again and increased foroperation, the current frequency is larger than or equal to F1*X%, frequency slow increasing control is conducted at the speed rate of Y / HZ till the frequency is increased to a target frequency, and when the frequency is smaller than F1*X%, frequency increasing control is conducted according to the normal speed rate. According to the technical scheme of the variable frequency air conditioner and the control method thereof, frequency oscillation can be reduced, noise is reduced, and comfort is improved.

Description

technical field [0001] The present invention specifically relates to the technical field of air conditioners, in particular to an inverter air conditioner and a control method thereof. Background technique [0002] With the improvement of the living standard of the social residents, in consideration of energy saving and comfort, the frequency conversion air conditioner is more and more popular in the market, and its application is becoming wider and wider. [0003] The frequency conversion air conditioners of the prior art generally protect the system, and the system protection generally includes frequency limiting, frequency reduction, and shutdown protection. Due to the complexity of the user's environment, the protection parameters may not be able to meet all protection conditions, and there may be problems with frequency oscillations. It will affect the user's comfort, and also produce frequency-up and down-frequency noise. Contents of the invention [0004] In view ...
