Refrigerants make air conditioning possible. Contained within the coils of an air conditioner, these liquid agents cool and dehumidify indoor air. For years, the most common refrigerant used in air-conditioning systems was R-22.
Today, in response to growing environmental concerns, production of systems using R-22 refrigerant is being phased out. Meanwhile, Thermal Zone is leading the industry in introducing systems that use an environmentally friendly alternative to R-22.
Acting in accordance with an international treaty called the Montreal Protocol, the U.S. Environmental Protection Agency (EPA) has mandated the phaseout of R-22 through the Clean Air Act. As of 2010, the manufacture of systems using R-22 refrigerant was prohibited, and by 2020 the production of R-22 itself must cease.
The main reason for this regulatory action is that R-22 is a hydrochlorofluorocarbon (HCFC) compound, which contains ozone-depleting chlorine.
Thermal Zone has transitioned to the manufacture of cooling systems that use the EPA-recognized chlorine-free R-410A refrigerant. Because R-410A contains no chlorine, it is considered ozone-friendly.
System matching - If you purchase an air conditioner that uses R-410A, your HVAC technician will need to inspect your indoor unit to see if it meets the performance requirements of the R-410A system. If the indoor unit is older, it will likely need replacing.
The most environmentally friendly air conditioning system in North America is the Thermal Zone model TZAB residential comfort cooling system with R407C refrigerant.
