Advanced CO2 Heat Pump Demonstration for Large Commercial Buildings

Project Description:

Funded by the California Energy Commission, ProspectSV, Flow Environmental Systems, DMG North, and Lawrence Berkeley National Laboratory are partnering to demonstrate Flow’s ANSWRTM CO2 Heat Pump system at the Department of Energy’s FLEXLAB® testing facility. There, the testbed will be configured to demonstrate the feature of simultaneous heating and cooling in large commercial buildings.

Technology Description:

ANSWR is a 100% electric heat pump platform utilizing safe and efficient refrigerant grade CO2 that can operate as a cooling-only chiller, heating-only heat pump or boiler, domestic water heater, or all at the same time with a single power feed as a simultaneous heating and cooling system. This innovative solution is expected to assist California in its goal to decarbonize large buildings.

Project Goals:

  • Evaluate the performance of the heat pump that uses an ultra-low GWP refrigerant in place of gas-fueled heating and water heating appliances

  • Decrease high first costs of heat pumps through an innovative modular-based design while combining heating and cooling system component in a product

  • Advance efficient and dynamic operations of heat pump system while providing simultaneous heating, cooling, and domestic hot water in large commercial buildings

Engagement:

Through ProspectSV’s outreach and education program, Pathways, this demonstration will bring resources and expertise to major industry and thought leaders including building owners, engineers, contractors, architects and more. Additionally, DMG North, a representative of leading HVAC equipment manufacturers in Northern CA, will permanently install this product in their Office and Training Center in San Jose, CA to provide industry training and education regarding the installation and commissioning of the heat pump.

Timeline:

~ 2 year project
