SAFETY AND COMPLIANCE OF HVAC-R EQUIPMENT IN RESIDENTIAL AND PROFESSIONAL APPLICATIONS

An insight into the potential hazards and the available Gas Sense solutions.

Introduction

The list of potentially hazardous substances in HVAC-R applications is long and diverse. From hotels, schools and hospitals to mechanical rooms, underground parking and industrial refrigeration, a wide array of target substances, technological considerations and regulatory requirements must be observed. Selecting and employing the appropriate gas detection system is an essential step towards mitigating associated combustion, toxicity and asphyxiation risks.

Refrigerant detection in hotels and living facilities:

In applications like hotels, dormitories, hospitals, and office buildings, Variable Refrigerant Flow (VRF) systems are commonly used. However, the high-volume design of VRF technology presents challenges, especially in multi-tenant settings. This is the case because a refrigerant leak in such systems can directly release the entire refrigerant charge into a room, posing an asphyxiation risk, particularly in occupied spaces. Furthermore, such incidents incur significant repair and recharge expenses, as well as a negative environmental impact.
To address this risk, safety standards such as EN 378 stipulate leak detection systems as a necessary safety requirement for centralized heating and refrigeration systems.

Refrigerant detection in demanding applications:

Gas detection applications such as industrial refrigeration, machine rooms, underground parking and etc., tend to place detectors in more demanding environments, which is reflected in regulatory requirements. Therefore, the challenges of these environments need to be addressed in order ot ensure the safety of assets and personnel. More specifically, this refers to higher enclosure protection grades and greater sensor stability.
In terms of monitored substances, the combustion, toxicity and asphyxiation risks of commonly used refrigerants such R-22, R-134a, and R-404A, NH3, CO2, HCS and HFCS, among others, need to be considered and effectively alleviated. The growing array of commonly used A2L, A2 and A3 flammable refrigerants also demands increased attention from a regulatory perspective.
