Kind Code:
A1
Abstract:
Provided are a control circuit, air conditioner, and control method, the control circuit comprising: a drive module (102); a drive circuit (104), the drive circuit (104) being connected to the drive module (102); a first switch module (106), the first switch module (106) being arranged on the drive circuit (104); a pressure detection module (108), the pressure detection module (108) being connected to the first switch module (106) and used for controlling the first switch module (106) to turn on or off, and thus controlling the drive circuit (104) to turn on or off. There is no need to arrange an additional pressure relief valve to prevent overpressure, the tightness of a pressure vessel is improved, and the leakage of cold medium is reduced; the control circuit is simpler, the response is quicker, the probability of control failure due to component damage is reduced, and the reliability of the control circuit is improved.
