What Is Refrigerant?

| My HVAC Price

Refrigerant is a chemical compound used in air conditioning and refrigeration systems to facilitate the transfer of heat between indoor and outdoor environments. It transitions between liquid and gas states to absorb and release heat.

The history of refrigerants is marked by various compounds used over the years, some of which had environmental and safety concerns. Early refrigerants included ammonia, sulfur dioxide, and hydrocarbons. In the 20th century, chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) were widely used but were found to contribute to ozone depletion.

Today, modern refrigerants like hydrofluorocarbons (HFCs) and hydrofluoroolefins (HFOs) are designed to have minimal impact on the ozone layer. Ongoing research aims to develop even more environmentally friendly alternatives.
