AI Technical Summary
Technical Problem
Existing air conditioning refrigerant detection systems cannot distinguish between target gas and interfering gas, leading to false alarms and causing panic among users.
Method used
A dual-channel detector is used. The test channel uses a narrowband filter, while the reference channel uses a notch filter. The controller determines the gas type based on the channel output voltage and calculates the gas concentration by fitting the relationship.
Benefits of technology
It enables the differentiation between target gas and interfering gas, avoids false alarms, and can accurately calculate the concentration of target gas, thereby improving detection accuracy and user safety.

Abstract
本发明公开了一种空调装置，包括冷媒探测系统，冷媒探测系统包括光源、双通道探测器和控制器，双通道探测器包括测试通道和参考通道，测试通道包括窄带滤光片，参考通道包括陷波滤光片，窄带滤光片和陷波滤光片的中心波长均与目标气体的中心波长相同；控制器用于获取测试通道当前输出电压和参考通道当前输出电压，根据测试通道当前输出电压判定是否存在目标气体，根据参考通道当前输出电压判定是否存在干扰气体。窄带滤光片只能让与中心波长相同的光通过，即与目标气体吸收波长相同的光通过，陷波滤光片可以让与中心波长相同的光不通过，其余波长光均可以通过，通过窄带滤光片可以判定是否存在目标气体，通过陷波滤光片可以判定是否存在干扰气体。
