What is CO2 refrigeration?

CO2 refrigeration refers to the use of carbon dioxide (CO2), also known as R-744, as a refrigerant in cooling systems. CO2 is considered an environmentally friendly alternative to traditional refrigerants because it has a very low global warming potential and no ozone depletion potential. CO2 refrigeration systems are commonly used in supermarkets, cold storage warehouses, and industrial applications due to their efficiency and sustainability. These systems can operate in both subcritical and transcritical cycles, depending on the ambient temperature and application. As the demand for eco-friendly cooling solutions grows, CO2 refrigeration is becoming increasingly popular in the HVACR industry.
