Abstract

The invention discloses an air conditioner, a control method and a control circuit thereof. The control circuit comprises a main controller, a first control branch circuit and an AC (Alternating Current) contactor, wherein the main controller is used for acquiring the power supply voltage of a power supply and outputting a first trigger signal when the power supply voltage is judged in the preset voltage range; the first control branch circuit is connected with the main controller and is used for boosting the power supply voltage when the first trigger signal is received, and outputting the boosted power supply voltage to the AC contactor; the AC contactor is arranged between the power supply and a compressor of the air conditioner and is connected with the first control branch circuit, the AC contactor is used for closing after receiving the boosted power supply voltage, so as to connect a power supply loop of the compressor. According to the invention, the technical problem that the air conditioner in the prior art can not work stably under 100-270V voltage is solved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner and its control method and circuit. Background technique [0002] The rated voltage of the existing fixed-frequency air conditioners is generally 220-240V, and the voltage fluctuation of the normal power grid is ±10%, that is, the existing fixed-frequency air conditioners generally work normally within the voltage of 198-264V. But for cities with unstable voltage (for example; Central Asia, Myanmar, Pakistan, etc.), due to the backward construction of the power grid and poor supporting facilities in the above-mentioned cities, the voltage is extremely unstable, and the voltage often fluctuates within 100-270V. At present, the stable minimum pull-in voltage of the main control device (i.e., AC contactor) in the mature application of fixed-frequency air conditioners is about 150V. In the early stage, the AC contactor manufacturer is asked to rectify the minimum pu...
