Abstract

The invention discloses an air conditioner fluorine deficiency detection control method and an air conditioner, and belongs to the technical field of air conditioners. The control method comprises the steps that the exhaust temperature of a compressor of the air conditioner is detected; the outer surface temperature of a body of the compressor is detected; according to the temperature difference value between the exhaust temperature and the outer surface temperature, the temperature range where the temperature difference value is located and the air conditioner fluorine deficiency quantity corresponding to the temperature range are determined; and a protection mode preset for air conditioner operation is controlled according to the air conditioner fluorine deficiency quantity. By means of the air conditioner fluorine deficiency detection control method, according to the exhaust temperature and the outer surface temperature of the compressor, the actual fluorine quantity of an air conditioner system can be judged by detecting the temperature change condition between the exhaust temperature and the outer surface temperature of the compressor, thus, protection measures can be timely taken when fluorine deficiency occurs to the air conditioner, and safe operation of the air conditioner is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method for detecting fluorine deficiency in an air conditioner and an air conditioner. Background technique [0002] Freon is a commonly used refrigerant medium in household or commercial air-conditioning and refrigeration systems. Since Freon completes the state transition of vaporization and liquefaction in the closed circulation system of the air conditioner, the general air conditioner does not need to add fluoride for at least 5 years or even until it is scrapped. In the existing air-conditioning products, due to the influence of factors such as the installation method of the air-conditioning and the welding quality of the air-conditioning pipes, there may be a problem of refrigerant leakage during the process of the air-conditioning. Reduced thermal effect, protective shutdown, indoor unit water leakage, and indoor evaporator freezing affect the normal us...
