According to a research report “Large-scale Natural Refrigerant Heat Pump Market by Refrigerant (Ammonia (R717), Carbon Dioxide (R744), Hydrocarbons), by Capacity (20–200 kW, 201–500 kW, 501–1,000 kW, Above 1,000 kW), by End Use (Commercial and Industrial), and by Region – Global Forecast to 2030″, the large scale natural refrigerant heat pump market is projected to reach USD 14.90 billion by 2030 from an estimated USD 7.28 billion in 2025, at a CAGR of 15.4% during the forecast period.
Large scale natural refrigerant heat pumps, particularly those using natural refrigerants, deliver superior performance through a high COP, enabling them to produce significantly more thermal energy per unit of electricity consumed than conventional heating systems. Their ability to extract and upgrade low-grade heat from ambient sources or industrial waste streams makes them an ideal technology for meeting stringent energy efficiency standards while contributing to long-term sustainability and cost optimization.

By capacity, 20–200 kW segment is expected to dominate the market during the forecast period.
The 20–200 kW capacity segment is increasingly in demand across a wide range of medium-sized commercial and institutional buildings, including hotels, educational facilities, healthcare centers, office buildings, and multi-unit residential complexes. These facilities require consistent, efficient, scalable heating and cooling solutions that adapt to varying load demands. Natural refrigerant heat pumps—using CO2, propane, or ammonia—are ideally suited for this segment, offering high energy efficiency, low environmental impact, and compliance with evolving building codes and climate policies. Their compact design, quiet operation, and ability to deliver heating and cooling make them particularly attractive for urban installations and retrofits.
By refrigerant, the Ammonia (R-717) segment is projected to be the second largest segment during the forecast period.
The Ammonia (R-717) segment is growing consistently as the global regulatory landscape is rapidly evolving to curb the use of high-GWP (Global Warming Potential) refrigerants, significantly influencing the market demand. Landmark policies—such as the EU’s F-Gas Regulation, the US AIM Act, and Canada’s HFC reduction plan—are mandating a phasedown of synthetic refrigerants with high climate impact. In response, commercial building owners are proactively transitioning to natural refrigerants like ammonia (R717). These substances offer ultra-low or zero GWP, regulatory compliance, and long-term viability. By adopting natural refrigerant heat pumps, commercial facilities can meet current and upcoming environmental mandates and enhance sustainability credentials, reduce operational risk, and ensure future readiness in a carbon-constrained economy.
By region, the Asia Pacific segment is anticipated to hold the largest market share during the forecast period.
Across the Asia Pacific region, there is a notable shift in both public perception and corporate responsibility regarding environmental sustainability. Heightened awareness of climate change, air quality, and resource efficiency influences consumer preferences and stakeholder expectations. At the same time, businesses are increasingly aligning with global ESG (Environmental, Social, and Governance) standards, integrating sustainability into their operations and value chains. This growing emphasis on climate-conscious practices fuels demand for clean, low-carbon technologies—such as large scale natural refrigerant heat pumps—which offer long-term environmental benefits, regulatory compliance, and reputational value. As a result, these systems are viewed not just as technical upgrades, but as strategic investments in corporate climate resilience and public trust.
