Abstract

The present invention provides a method and device for determining the corresponding relationship of temperature sensors, and an air conditioner. The air conditioner includes a plurality of internal units, each of which includes a plurality of temperature sensors, and the plurality of temperature sensors are respectively arranged on the liquid pipe, the middle pipe and the gas pipe. A plurality of temperature sensors include a liquid pipe temperature sensor, a medium pipe temperature sensor, and an air pipe temperature sensor. The method is applied to an air conditioner, and the method includes controlling the air conditioner to operate in a cooling mode; The temperature collected by each temperature sensor; according to the temperature collected by the liquid pipe temperature sensor and gas pipe temperature sensor of the indoor unit, the ambient temperature of the indoor unit, the low pressure saturation temperature in the middle pipe, the opening degree of the expansion valve of the internal unit and the internal temperature of the air conditioner The temperature collected by the middle pipe temperature sensor of the machine and other internal machines is used to determine the temperature sensors corresponding to the liquid pipe, the gas pipe and the middle pipe respectively from a plurality of temperature sensors. The solution of the embodiment of the present application can determine the temperature sensors of the air conditioner corresponding to the liquid pipe, the air pipe, and the middle pipe respectively.

Description

technical field [0001] The present invention relates to the technical field of air-conditioning control, in particular to a method and device for determining the corresponding relationship of temperature sensors, and an air-conditioner. Background technique [0002] In air conditioners, there are liquid pipe temperature sensors, middle pipe temperature sensors, gas pipe temperature sensors and ambient temperature sensors. The liquid pipe temperature sensor is used to detect the temperature of the liquid pipe of the internal machine, the middle pipe temperature sensor is used to detect the temperature of the evaporator in the internal machine, and the air pipe temperature sensor is used to detect the temperature of the air pipe of the internal machine. Therefore, the liquid pipe temperature sensor, the middle pipe temperature The installation positions of the sensor and the air pipe temperature sensor are very close, and for the liquid pipe temperature sensor, the middle pipe...

AI Technical Summary

Problems solved by technology

The liquid pipe temperature sensor is used to detect the temperature of the liquid pipe of the internal machine, the middle pipe temperature sensor is used to detect the temperature of the evaporator in the internal machine, and the air pipe temperature sensor is used to detect the temperature of the air pipe of the internal machine. Therefore, the liquid pipe temperature sensor, the middle pipe temperature The installation positions of the sensor and the air pipe temperature sensor are very close, and for the liquid pipe temperature sensor, the middle pipe temperature sensor and the air pipe temperature sensor itself, the shape and color of each temperature sensor are also very similar. Therefore, in the air conditioner assembly process , it is very easy to connect the liquid pipe temperature sensor, the middle pipe temperature sensor and the air pipe temperature sensor wrongly, which will affect the operation effect of the air conditioner

After the temperature sensor is wrongly connected, it usually needs to be disassembled for maintenance
