ASHRAE, or the American Society of Heating, Refrigerating, and Air-Conditioning Engineers, is a professional organization that develops standards for the design, construction, and operation of buildings and other structures. In its refrigerant classification system, ASHRAE classifies refrigerants as either A1, A2, A3, or B1, based on their toxicity and flammability.

An A1 class refrigerant is a type of refrigerant that is classified as being non-toxic and non-flammable, according to ASHRAE standards. These types of refrigerants are considered to be the safest to use in refrigeration and air conditioning systems.

In mission critical systems, such as data centers and hospitals, the air conditioning system is a vital component that must be maintained at all times to ensure the proper functioning of the equipment and to protect the health and safety of people. If there is a leak of an A1 class refrigerant, it can have a significant impact on the efficiency of the system, which can lead to costly repairs and downtime.

It is important to detect leaks of refrigerants in mission critical systems to minimize the risk of damage and to ensure the system is operating at peak efficiency. Sensors can be used to detect refrigerant leaks, and InfraSensing offers a range of infrared sensors that are specifically designed for this purpose.

Infrared sensors from InfraSensing can be integrated into a Building Management System (BMS) via Modbus TCP, which is a common protocol for communication between devices in a building automation system. By integrating leak detection sensors into a BMS via Modbus TCP, it is possible to monitor the status of the sensors in real-time, and to take appropriate action if a leak is detected. This can help to prevent costly repairs, and can also help to protect the environment by minimizing the release of refrigerants into the atmosphere.
