Web31 aug. 2024 · R-410A is the most common refrigerant used in HVAC systems to this day. However, R-410A will ultimately be phased out and replaced with refrigerants like R-32, which is used in some LG HVAC solutions. R-32 conveys heat more efficiently than other refrigerants and can reduce the consumption of electricity. WebAs the name implies, secondary refrigerants are those liquids, which are used for transporting thermal energy from one location to other. Secondary refrigerants are also known under the name brines or antifreezes. of course, if the operating temperatures are above 0oC, then pure water can also be used as secondary refrigerant, Application:
