Advanced R744 Heat Pump for simultaneous heating and cooling with advanced energy optimization and defrost strategies.

Project Innovation

ProspectSV, Flow Environmental Systems, DMG North, and Lawrence Berkeley National Laboratory (LBNL) are partnering to demonstrate an advanced, cost-competitive, high-efficiency large air-source and water-source heat pump using ultra-low GWP refrigerant. This project aims to evaluate the performance of the heat pump in replacing gas-fueled heating and water heating appliances while reducing initial costs through innovative modular design. Additionally, it seeks to advance efficient and dynamic operations of heat pump systems in large commercial buildings, providing simultaneous heating, cooling, and domestic hot water. DMG North will also host one of the heat pumps to facilitate knowledge transfer and presentations to industry leaders involved in building systems and maintenance.
