Temperature sensor corresponding relation determination method and device and air conditioner

Abstract

The invention provides a temperature sensor corresponding relation determination method and device and an air conditioner. The air conditioner comprises a plurality of indoor units, wherein each indoor unit comprises a plurality of temperature sensors, the plurality of temperature sensors are arranged on a liquid pipe, a middle pipe and an air pipe, and the plurality of temperature sensors comprise a liquid pipe temperature sensor, a middle pipe temperature sensor and an air pipe temperature sensor. The method is applied to the air conditioner and comprises the steps that the air conditioner is controlled to operate in a refrigeration mode; in the operation process of the air conditioner, aiming at each indoor unit, the temperature collected by each temperature sensor in each indoor unit is obtained; according to the temperature collected by the liquid pipe temperature sensors and the air pipe temperature sensors of the indoor units, the indoor unit environment temperature, the low-pressure saturation temperature in the middle pipes, the opening degree of indoor unit expansion valves and the temperature collected by middle pipe temperature sensors of the indoor units and other indoor units in an air conditioner, and temperature sensors corresponding to the liquid pipe, the air pipe and the middle pipe are determined from the multiple temperature sensors. According to the scheme, the temperature sensors, corresponding to the liquid pipe, the air pipe and the middle pipe, of the air conditioner can be determined.

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
