Problems solved by technology

However, during the transportation or installation process of the air conditioner, the exhaust temperature sensing package may become loose. When the exhaust temperature sensing package is loose, the detected temperature is close to the ambient temperature, but lower than the exhaust temperature of the compressor. Errors in the temperature detection of the discharge temperature package, for example, when the compressor is actually running overheated, the detected temperature is lower than the discharge temperature of the compressor because the discharge temperature sensor is loose, and the opening of the electronic expansion valve at this time temperature may continue to decrease, the discharge temperature of the compressor will continue to rise, resulting in overheating of the compressor, or even damage to the compressor
[0003] Therefore, some air conditioners can detect whether the exhaust temperature sensing package is loose, and can avoid damage to the compressor, but they cannot adjust the state of the air conditioner according to the working conditions, resulting in a decrease in the cooling and heating comfort of the air conditioner

Abstract

The invention discloses a control method of an air conditioner. The control method of the air conditioner comprises the steps: judging whether an exhaust temperature sensing bulb is loosened or not; and if yes, acquiring the current operation mode and the outdoor temperature, and controlling the operation frequency of a compressor and the opening degree of an electronic expansion valve according to the current operation mode and the outdoor temperature. According to the control method of the air conditioner, the opening degree of the electronic expansion valve and the operation frequency of the compressor can be adjusted according to the working conditions, the compressor can be prevented from being damaged due to overheating, and the refrigerating and heating comfort is higher.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method. Background technique [0002] The air conditioner is equipped with a discharge temperature sensing package, which is usually installed near the exhaust port of the compressor to detect the discharge temperature of the compressor, and judge whether the operating parameters of the compressor match the current target through the discharge temperature temperature, and whether the operating parameters of the compressor are within a reasonable range. However, during the transportation or installation process of the air conditioner, the exhaust temperature sensing package may become loose. When the exhaust temperature sensing package is loose, the detected temperature is close to the ambient temperature, but lower than the exhaust temperature of the compressor. Errors in the temperature detection of the discharge temperature package, for exam...
