The operational capability of most residential climate control systems relies on a refrigerant. This substance circulates within a closed-loop system, absorbing heat from inside the dwelling and releasing it outdoors. Historically, a specific type of refrigerant, known by a trade name, was commonly utilized in these appliances.
The widespread adoption of this specific refrigerant presented certain environmental challenges. Scientific research revealed its detrimental impact on the ozone layer, leading to international agreements aimed at phasing out its production and use. This concern underscored the necessity for more environmentally benign alternatives.
