Air conditioner exhaust superheat correction method, device, computer product and air conditioner

Abstract

The invention provides a method, a device, a computer product and an air conditioner for correcting the exhaust superheat degree of an air conditioner, and relates to the technical field of air conditioners, the problem that the overall power of an air conditioner is high and the reliability risk is large due to the fact that the detection value of the exhaust superheat degree is high is solved. The correction method comprises the following steps of acquiring the operation frequency of the compressor and the exhaust superheat degree detection value of the air conditioner in real time; judgingwhether the air conditioner meets the all access conditions of the exhaust superheat degree detection value correction process, the entering condition comprises that the difference value of the exhaust superheat degree detection value and the exhaust superheat degree setting value is larger than or equal to a preset difference value, and the operation frequency is larger than or equal to the firstpreset operation frequency; if yes, entering a correction process for reducing and correcting; and if not, obtaining the operation frequency of the compressor at the next moment and the detection value of the exhaust superheat degree of the air conditioner. The correction method is applied to the correction of the detection value of the exhaust superheat degree of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner exhaust superheat correction method, device, computer product and air conditioner. Background technique [0002] In an air conditioner, the discharge temperature sensor is usually set within 15 centimeters from the discharge end of the compressor of the air conditioner, so as to monitor the body temperature of the compressor. [0003] The discharge superheat (Discharge Superheat, DSH for short) of the air conditioner is an important parameter for controlling the opening of the expansion valve of the air conditioner. When the exhaust superheat of the air conditioner increases, the expansion valve opening of the air conditioner will increase to increase the amount of refrigerant circulation. The detected value of the exhaust superheat is generally equal to the detected value of the exhaust gas temperature minus the high pressure saturation temperature o...
