Abstract

The invention provides a control method and a control device of an air-conditioner, and an air-conditioner, wherein the air-conditioner comprises a refrigeration system, an indoor fan, and an outdoor fan; the control method of the air-conditioner comprises the following steps: when an instruction of starting the air-conditioner is received, detecting an operating mode of the air-conditioner and detecting a discharge pressure of a compressor in the refrigeration system; and controlling the indoor fan and/or the outdoor fan according to the discharge pressure and the operating mode of the air-conditioner so as to control a pressure of the refrigeration system. The technical solution of the present invention is capable of immediately controlling the indoor fan and/or the outdoor fan to ensure that the system pressure is adjusted to a non-stop pressure range upon detecting abnormal discharge pressure of the compressor; in such a manner, smooth start and reliable operation of the air-conditioner system are guaranteed, and therefore, the comfort of a user using the air-conditioner is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner control device and an air conditioner. Background technique [0002] When the existing air conditioner is turned on in the high-temperature cooling mode, the system pressure rises faster than the temperature sensed by the sensor, causing the system to directly enter the high-voltage protection shutdown when it is too late to take a protective action to reduce the pressure, which affects the use of users comfort. [0003] Similarly, in the heating mode, especially when the indoor and outdoor ambient temperature difference is high, it is easy to cause abnormally large starting current of the compressor at the moment of starting, and the system pressure suddenly rises, which will also cause the system to make a proper pressure reduction in time. If the protection action is not activated, it will directly enter t...
