Refrigerant Leak Alarm - SKA/NE-301(R134a)
数据中心机房冷媒泄漏气体报警器
Common refrigerants used in data center precision air conditioning: R134a, R410A, R32, R454B, etc. Refrigerant leakage can displace oxygen and cause suffocation. R32 is also mildly flammable. The refrigerant leak alarm system consists of on-site detectors and an alarm controller, enabling 24-hour online monitoring, audible and visual alarms, linked exhaust ventilation, and integration with the dynamic environment monitoring system.
Product Introduction
数据中心机房冷媒泄漏气体报警器
数据中心精密空调常用冷媒:R134a、R410A、R32、R454B等,冷媒泄漏会挤占氧气造成人员窒息,R32 还具备弱可燃性,冷媒泄漏报警器由现场探测器 + 报警控制器组成,实现 24h 在线监测、声光报警、联动排风、对接动环监控。
一、传感器原理选型(机房优先 NDIR 红外)
- NDIR 非分光红外(首选) 抗干扰强、寿命 810 年、漂移小,不受温湿度、灰尘、清洗剂干扰;适配R134a/R410A/R32/R454B,数据中心主流方案。
- 电化学传感器:成本低,寿命 23 年,易漂移,需要频繁校准,不建议机房长期使用。
- PID 光离子:适合微量检漏,对部分冷媒选择性差,多用于便携式检漏仪。
量程建议:05000ppm,分辨率 1ppm;输出接口:4-20mA、RS485-Modbus RTU,方便接入动环系统。
二、报警阈值(工程通用设置)

三、安装布点关键要点
- 安装高度(看冷媒密度)
- R134a、R410A:气体重于空气,探测器距离地面0.30.6m安装。
- R32(比空气轻):探测器装在吊顶下方0.30.6m,气体容易聚集顶部。
- 布点位置
- 重点:精密空调压缩机、冷媒阀门、法兰、软管接头、管路焊缝周边。
- 单探测器有效覆盖半径≤7.5m;避开风机直吹、出风口、强电磁设备,预留校准检修空间。
