Refrigerants transfer heat in Direct Expansion (DX) systems. Air conditioners and heat pumps use refrigerants to move energy from one environment to another. For example, a system can transfer heat from inside a building to the outside, or the other way around.
Refrigerants can carry significantly more energy per kilogram than common heat-transfer fluids. They can carry about 10 times more energy than water and 50 times more than air.
Refrigerants require careful handling because they can operate at high pressures and extreme temperatures. System pressures can range from 100 to 145 psi, while refrigerant temperatures can range from -50°C to 145°C.
Safety classifications also vary by refrigerant. A1 refrigerants have low flammability and are non-flammable. A2 and A2L refrigerants have higher flammability, while A3 refrigerants are highly flammable. Refrigerants also have different toxicity levels, classified as B1 (low), B2 (medium), and B3 (high).
ISO 817 and ASHRAE 34 define these refrigerant safety classifications. Because of the potential risks, qualified and certified engineers should handle refrigerants and related systems.
Certification requirements vary by country and refrigerant class. In the UK, for example, technicians may require C&G 2079 certification for A1 refrigerants, along with C&G 6187-2 certification for A2, A2L, and A3 refrigerants.
