Abstract

The invention provides a sensor light path assembly, a gas sensor, a measuring method and an air conditioning system. The sensor light path assembly comprises a fixing base and a sliding block, the sliding block and the fixing base are provided with light reflecting faces respectively, and the two light reflecting faces are arranged in parallel in an inclined mode. The sliding block can move in the parallel direction relative to the fixing base. Besides, the assembly also includes a light source and a detector; light emitted by the light source is reflected by the two reflecting faces and then reaches the detector; the light source is arranged on the fixing base, and the detector is arranged on the sliding block; or the light source is arranged on the sliding block, and the detector is arranged on the fixing base. Through the movement of the sliding block, the reflection times of the light can be changed, so that the propagation path length of the light path is variable.

Description

technical field [0001] The application belongs to the technical field of air conditioning systems, and in particular relates to a sensor optical path assembly, a gas sensor, a measurement method, and an air conditioning system. Background technique [0002] With the improvement of people's living standards, the attention to the air quality in the environment is also increasing. In order to meet the monitoring of air quality, environmental sensors such as air quality sensors (CO 2 , PM2.5) and other market demands are increasing. Carbon dioxide concentration is one of the important indicators to measure air quality. There are already various sensors for detecting carbon dioxide concentration on the market. Carbon dioxide sensors based on non-dispersive infrared (NDIR) technology have become popular due to their good stability and high precision. . [0003] The optical path length of the gas chamber of the existing NDIR carbon dioxide sensor is fixed, which cannot be well ad...
