The invention provides a compressor exhaust temperature detection value correction method and device, a storage medium and an electric appliance. The method comprises the steps of detecting whether ornot a high-voltage protection fault appears; when it is detected that the high-voltage protection fault appears, judging whether or not an exhaust temperature detection value of the unit reaches a set temperature threshold value; if the exhaust temperature detection value does not reach a set temperature threshold value, correcting the exhaust temperature detection value. According to the scheme,the exhaust temperature can be calibrated on the condition that the unit exhaust temperature detection value is not accurate, and the unit can work normally.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a correction method, device, storage medium and electrical appliances for the detection value of the discharge temperature of a compressor. Background technique [0002] At present, the exhaust temperature is generally used in the control of air energy water heaters and air conditioners. After the compressor is started, the exhaust temperature will gradually rise. During the normal operation of the unit, the exhaust temperature should be kept within a certain range. When the temperature exceeds a certain value, the program will control the opening of the electronic expansion valve to reduce the exhaust temperature. The common method in the industry to collect exhaust gas temperature is to weld a special sensor fixing sleeve on the exhaust pipe, such as Figure 7 As shown, put heat-conducting silicone grease inside the sensor fixing sleeve, then put the exhaust temperature sen...
