Fool-proof method for exhaust gas temperature sensors of air conditioning system

Abstract

The invention discloses a fool-proof method for exhaust gas temperature sensors of an air conditioning system. The air conditioning system comprises a plurality of compressors, wherein the exhaust gas temperature sensor is arranged at an exhaust port of each compressor, respectively. The method comprises the following steps: when the air conditioning system is booted, acquiring the temperature value detected by each exhaust gas temperature sensor as the first temperature value; controlling one compressor of the plurality of compressors to be booted and acquiring the temperature value detected by each exhaust gas temperature sensor as the second temperature value; and identifying the exhaust gas temperature sensor corresponding to the compressor which is booted according to a change condition between the second temperature value and the first temperature value. The method can identify the exhaust gas temperature sensor corresponding to the compressor which is booted according to a change condition between the second temperature value and the first temperature value so as to prevent the exhaust gas temperature sensors from being mistakenly inserted, so that the degree of automation is high and the increase of materials is not caused.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a foolproof method for an exhaust temperature sensor of an air conditioning system. Background technique [0002] For air conditioning systems with multiple compressors, each compressor contains a discharge temperature sensor for control and protection of the air conditioning system. [0003] In the related art, in order to prevent the wrong position of the exhaust temperature sensor, it is usually marked by labeling. This method completely relies on people to determine the corresponding exhaust temperature sensor of different compressors, and the degree of automation is low and error-prone; or It is to make the plugs of different exhaust temperature sensors into different styles, but this method will lead to more materials. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain ext...
