Refrigerant Gas Detectors
Refrigerant gases are chemical compounds used in cooling and air conditioning systems to transfer heat from one place to another. They act as the working fluid inside equipment such as domestic refrigerators, commercial cold storage units, heat pumps and large HVAC systems. Their primary purpose is to absorb heat from one environment and release it elsewhere, making controlled cooling possible.
Refrigerants operate within a closed system through what is known as the vapour-compression refrigeration cycle. In this cycle, the refrigerant absorbs heat and evaporates from a liquid into a gas. The gas is then compressed, which increases its pressure and temperature. As it flows through the condenser, it releases the absorbed heat and turns back into a liquid. The liquid then passes through an expansion device, where its pressure drops rapidly, cooling it down before it re-enters the evaporator to repeat the process. This continuous cycle allows fridges to keep food cold, air conditioning systems to cool buildings, and heat pumps to provide temperature control.

FAQs
A refrigerant gas is a chemical compound used within cooling and air conditioning systems to absorb heat from one area and release it elsewhere. It circulates inside a sealed system and changes between liquid and gas states to enable temperature control.
Refrigerants work through the vapour-compression cycle. They absorb heat as they evaporate into a gas, are compressed to raise their temperature, release heat as they condense back into a liquid, and then expand to cool down before repeating the cycle.
Older systems used chlorofluorocarbons such as Dichlorodifluoromethane, which were phased out due to ozone damage. They were replaced by hydrochlorofluorocarbons like Chlorodifluoromethane. More recently, hydrofluorocarbons such as 1,1,1,2-Tetrafluoroethane became common, although these are now being phased down due to their high Global Warming Potential.
