Project Objective

This project aims to develop a regenerative air source heat pump for commercial and industrial heating, ventilation, and air conditioning (HVAC) applications. By using air as the working fluid, the heat pump eliminates all use of hydrofluorocarbon (HFC) refrigerant—a major greenhouse gas. The heat pump will operate over a temperature range of -40°F to 210°F, enabling excellent performance in both cold climates and industrial applications. The initial units will have a 20-ton cooling capacity and a 240,000 British thermal units (Btu)/hour heating capacity—a 50% improvement over existing state-of-the-art technology. The efficiency improvements from this heat pump are expected to create a payback period of four years for the target markets.
