Refrigerants play a crucial role in our daily lives, powering the air conditioners and refrigeration systems that keep our homes, offices, and supermarkets cool. However, the widespread use of certain types of refrigerants has raised concerns about their impact on the environment. In this blog, we will explore the global scenario of refrigerant usage, examining the evolution of refrigerants, their environmental implications, and the ongoing efforts to strike a balance between innovation and sustainability.
Global HVAC&R Market Overview:
A recent survey of market trends revealed that purchases of HVAC&R systems grew year on year. As per global HVAC&R market overview the global HVAC&R market is projected to reach $257.9 billion by 2027, with a CAGR of 5% during the forecast period of 2022-2027. Factors driving this growth include increasing population, rapid urbanization, changing weather conditions, and innovations in the HVAC&R industry.
Moreover, the HVAC&R industry has witnessed the adoption of environmentally friendly refrigerants. The introduction of these refrigerants with lower environmental impact, such as CO2, A2L and A3 refrigerant, presents significant opportunities for the HVAC market.
HFC Refrigerant Phase Down:
The global phase-down of hydrofluorocarbons (HFCs) is a crucial initiative aimed at mitigating climate change by reducing the use and production of these potent greenhouse gases. The phase-down is part of the Kigali Amendment to the Montreal Protocol, an international treaty established to protect the ozone layer. The Kigali Amendment targets the reduction of HFC production and consumption globally. Countries committed to the Kigali Amendment are gradually phasing down HFCs, with developed nations taking the lead in initiating reductions followed by developing nations in subsequent years. By 2048, all of the countries are not to consume more than 15% to 20% of what they currently consume (based on CO2 equivalence).
Refrigerant Usage by Region:
The implementation of the Kigali Amendment to the Montreal Protocol was ongoing, and different countries were at various stages in their commitments to phase down hydrofluorocarbons (HFCs), and adapting 4th generation refrigerant which are environmentally free and focused on low GWP. In order to satisfy the interests of air conditioning and refrigeration, the evaluation of refrigerant begins with the first generation, which employs any available substances fulfill the refrigeration interest. In a later stage (2nd generation), generation were concentrated on durability and reliability (R12 and R22 more popular in second generation). Third generation evaluations focus on ozone layer protection and R134a and R152a have grown in popularity. Concerns about global warming have been expressed over time and during the evaluation of refrigerants worldwide. In response, rules were developed at the national level to gradually phase out environmentally harmful refrigerants and ensure that the fourth generation of refrigerants has a low GWP value.
Refrigerant adoption in a major contributor in the HVAC&R industry: European Union, ASIA, USA.
| Application | ASIA | EU | USA |
| Spilt AC | R22 > R410A | R22 > R410A > R32 > R290 | R410A > R32 > R454B |
| VRF | R410A > R32 | R410A > R32 | R410A > R32 |
| Heat pump | R410A > R32 | R410A > R32 > R290 | R410A > R290 |
| Chillers | R410A > R32 | R410A>R32>R290 | R410A > R32 > R454B |
North America:
The United States and Canada have been transitioning towards low-global-warming-potential (GWP) refrigerants in response to regulations aimed at phasing down high-GWP HFCs. A focus on natural refrigerants like hydrocarbons (HCs) and hydrofluoroolefins (HFOs) has been observed.
Europe:
The European Union has been at the forefront of implementing strict regulations to phase down HFCs, with the F-Gas Regulation being a key driver. Increasing adoption of natural refrigerants viz. CO2 and HFOs is evident in various applications.
Asia-Pacific:
China has been actively working on phasing down HFCs, adopting policies and regulations to promote the use of alternative refrigerants. Japan and South Korea have also been aligning with global efforts to transition to lower-GWP refrigerants.
India:
India has been gradually implementing measures to reduce the use of high-GWP refrigerants, focusing on adopting alternatives with lower environmental impact.
Middle East and Africa:
Some countries in the Middle East have been taking steps to regulate and reduce the use of high-GWP refrigerants. Awareness and regulatory frameworks for sustainable refrigerants are emerging in parts of Africa.
Next-Generation Refrigerants:
Efforts were underway to transition to more environmentally friendly alternatives. Some of the promising alternatives included hydrofluoroolefins (HFOs) and natural refrigerants such as hydrocarbons (HCs) and carbon dioxide (CO2).
Hydrofluoroolefins (HFO): Hydrofluoroolefins (HFOs) are a class of synthetic refrigerants designed to be more environmentally friendly than traditional hydrofluorocarbons (HFCs). HFOs have gained attention as potential alternatives because they have lower global warming potential (GWP). GWP measures the heat-trapping ability of a substance over a specific time period, with lower values indicating a reduced impact on global warming. R454B is emerging as a key refrigerant alternative to the widely used R410A in the HVAC industry, with a lower Global Warming Potential (GWP).
Natural Refrigerants: Natural refrigerants are a 4th generation refrigerant and a revolution in HVACR industries. Refrigerants like CO2 (R744), ammonia (R717), and propane (R290) and isobutane (R600a) are more popular hydrocarbon refrigerant in industry. Natural refrigerant that has been gaining popularity in various applications, such as commercial refrigeration and industrial systems.

Conclusion
In conclusion, the global HVAC&R industry is undergoing a significant transformation driven by the imperative to balance innovation with sustainability. The escalating demand for air conditioning and refrigeration systems, fueled by factors like population growth, urbanization, and changing weather conditions, has led to a booming market projected to reach $257.9 billion by 2027. However, the environmental impact of traditional refrigerants, particularly hydrofluorocarbons (HFCs), has prompted a paradigm shift towards greener alternatives. The global phase-down of HFCs, as outlined in the Kigali Amendment to the Montreal Protocol, underscores the international commitment to mitigating climate change by reducing the use of potent greenhouse gases. Nations are progressively adopting environmentally friendly refrigerants like CO2, A2L, and A3, marking a pivotal moment in the industry’s evolution. Regionally, North America, Europe, Asia-Pacific, India, and the Middle East and Africa are actively engaged in transitioning to low-global-warming-potential refrigerants, driven by regulatory measures and an increasing awareness of environmental sustainability.
