Low-GWP Alternatives in Commercial Refrigeration and A/C
HFC's are the fastest GHGs increasing about 10 - 15% annually. The demand for cool spaces and energy use has more than tripled between 1990 and 2016 (600 TWh to 2,000 TWh).
A. Messe was founded in 1899 long before the first refrigerants of ammonia and hydrocarbons were used in the first electric refigerators invented in 1913.
HCFC-22 Freon refrigerant is used in several applications like chillers, cold storage, retail refrigeration equipment, air conditioners, and industrial process refrigeration. On Jan 1, 2020, USA production and import of HCFC-22 ended.
The goal is to replace high-GWP HFCs with Low-GWP alternatives. Because of HFCs annual growth, regulations should have a significant impact on their production and use. Reducing the use of HFCs will have an impact on global temperature rise.
Some of the new low-GWP alternatives have lower flammability and toxicity and are classified as A2L by ASHRAE.
