Intelligent detection method of air conditioner

Abstract

The invention discloses an intelligent detection method of an air conditioner. The intelligent detection method comprises the steps: 1) roughly selecting the number of shunt circuits ON in a standard indoor unit according to the cooling capacity of an outdoor unit detected; 2) starting temperature sensors in the shunt circuits ON to detect the real-time temperature; when the outlet temperature of indoor heat exchangers in the shunt circuits is lower than the preset difference value of a coil temperature, turning on more than one shunt circuit; and so on, till the outlet temperature of the indoor heat exchangers in the shunt circuits is higher than the coil temperature; 3) upon completion of calibration of the standard indoor unit, state locking, locking the opening state of electronic expansion valves of the shunt circuits and the corresponding outdoor unit detected.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an intelligent detection method for an air conditioner. Background technique [0002] At present, the air conditioner needs rapid detection in the production process. For example, the Chinese patent application number 201410455858.7 discloses a standard internal unit and a commodity inspection system for testing the cooling and heating capacity of the external unit of the air conditioner. There is a liquid for heat exchange in the box; There are liquid inlets, liquid outlets, multiple refrigerant inlets and multiple refrigerant outlets and exhaust valves corresponding to the refrigerant inlets. The tank is equipped with water-liquid stirring devices, multiple refrigerant heat exchange tubes, and temperature sensing devices. and the electric heating device, the two ends of the refrigerant heat exchange tube are connected with the corresponding refrigerant inlet and refrigerant outlet, and the...

Problems solved by technology

[0004] 1. Due to the limitation of the type of the standard internal unit, it does not match the external unit system; when the internal unit system is too large, the system will store fluid in the internal unit, resulting in insufficient fluid in the unit; correspondingly, the system is too small, resulting in excessive fluid in the unit; If the state of the unit does not match with that of the external unit, it will lead to distortion of the operating parameters of the unit

[0005] 2. Since the temperature of the test environment in the operating room is relatively fixed, and the temperature cannot meet the temperature requirements of the harsh working conditions of the unit, and the unit is under light load, the abnormal vibration of the piping of the system cannot be detected in time

[0006] 3. The average value of the operating power of multiple units is used as the judgment standard, and a fluctuation range is set as the basis for judging whether the unit is short of liquid, which cannot reflect the individual condition of the unit in time, and the judgment standard is not accurate
