The global HVAC-R market was valued at $193.6 billion in 2021 and is projected to reach $257.9 billion in 2027, following a CAGR of 5% during the forecast period 2022-2027. The growth in the global HVAC-R market is expected to be driven by increasing population and rapid urbanization, drastic change in weather conditions, and emerging innovation in HVAC-R.

The European Economic and Social Committee (EESC), a key EU advisory body, has released its opinion on the proposed EU F-gas Regulation, calling for a ban on all refrigerants with a GWP above five in new heat pumps, room air conditioners, chillers and refrigeration applications as of 2030.

Refrigerants market is expected to reach at USD 8.4 billion in 2027 at a CAGR of 6.2% during the forecast period. The most used natural refrigerants are ammonia, carbon dioxide, and HCs such as propane and isobutene. Technological advancements in cooling equipment are replacing traditional refrigerants such as HCFC and HFC with natural ones. This has increased the market share of natural refrigerants in applications such as air conditioning, refrigeration, and heating systems.
