Abstract

The invention discloses a control method of an air conditioner electronic expansion valve and an air conditioner. The control method of the air conditioner electronic expansion valve comprises the following steps that an exhaust temperature of a compressor after a first preset period of air conditioner operation and an exhaust temperature of the compressor after a second preset period of air conditioner operation are obtained; an temperature difference value between the exhaust temperature of the compressor after the first preset period of air conditioner operation and the exhaust temperatureof the compressor after the second preset period of air conditioner operation is calculated; and when the temperature difference value is greater than a preset temperature difference value, the present opening of the air conditioner electronic expansion valve is controlled to be increased. According to the control method of the air conditioner electronic expansion valve and the air conditioner, the problems that the electronic expansion valve is controlled improperly, the air conditioner still controls the electronic expansion valve by an original control method, the abnormal exhaust temperature of the compressor is caused, and even abnormal operation of the entire air conditioner is caused are solved.

Description

Technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner electronic expansion valve and an air conditioner. Background technique [0002] With the continuous development of science and technology, more and more electrical equipment enters people's daily life and work, such as air conditioners, televisions, or computers. The air conditioner can provide users with a comfortable environment through cooling or heating, and can adjust operating parameters such as temperature and wind speed according to the user's control. [0003] However, when the electronic expansion valve is adjusted according to the user's control instructions, improper control of the electronic expansion valve may occur, resulting in abnormal compressor discharge temperature, and even abnormal operation of the entire air conditioner. [0004] The foregoing content is only used to assist in understanding the technical solution of ...
