Air conditioner and control method and device of air conditioner

Abstract

The invention discloses an air conditioner and a control method and device of the air conditioner. The method comprises the following steps: an indoor refrigerant concentration is obtained; a refrigerant leakage grade of the air conditioner is determined according to the refrigerant concentration; and the air conditioner is controlled to execute actions matched with the refrigerant leakage level.According to the control method of the air conditioner, when refrigerants are leaked, the refrigerant concentration is detected in real time, and different treatment measures are adopted according tothe concentration magnitude, that is, a classified-detection and classified-treatment mode is used, so that the control method is more reasonable, the problem of resource waste caused by consistent treatment methods for less or more leakage of the refrigerants in the prior art is solved, and the control method is simple and easy to realize.

Description

technical field [0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioner and a control method and device for the air conditioner. Background technique [0002] Refrigerant plays a very important role in energy saving and emission reduction, but due to the characteristics of the refrigerant, the refrigerant has the danger of being flammable or even explosive. If the concentration of the refrigerant reaches a certain value, it may cause combustion or even explosion when it encounters a fire source. There is a certain risk to people's life and property safety. [0003] In related technologies, when a refrigerant leak is detected, the risk of greater harm can be reduced by taking measures such as controlling the indoor fan and issuing a leak alarm. [0004] However, in the related art, the judging condition is relatively simple before the corresponding control method is adopted for refrigerant leakage. For exampl...

Problems solved by technology

[0006] For this reason, the first purpose of this application is to propose a control method for an air conditioner. This method detects the refrigerant concentration in real time when the refrigerant leaks, and adopts different processing measures according to the concentration, that is, uses hierarchical detection and classification The processing method makes the control method more reasonable, and solves the problem in the prior art that when the refrigerant leakage is small or large, the control method adopted is consistent, resulting in waste of resources, and is simple and easy to implement
