ProspectSV

Project Description:

Funded by the California Energy Commission, ProspectSV, Flow Environmental Systems, DMG North, Lawrence Berkeley National Laboratory, Straus Family Creamery, Avida Energy, and Alter Engineers are partnering to demonstrate Flow’s ANSWR™ CO2 Heat Pump system at multiple cold storage sites at Straus’ dairy manufacturing facility in Rohnert Park, CA. There, the heat pump system will provide low and medium temperature refrigeration with advanced defrost controls and thermal storage.

Technology Description:

ANSWR is a 100% electric heat pump system 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 integrated solution provides low temperature and medium temperature refrigeration by reclaiming heat from the refrigeration cycle to defrost for little to no energy.

Project Goals:

Demonstrate the ANSWR heat pump and evaluate its ability to deliver efficiency, peak load reduction and shifting, waste heat recovery, and advanced defrost control.
Reduce operational costs and GHG emissions currently associated with commercial cold storage
Demonstrate benefits to end users and provide market-specific data, strategies, and tools from testing data and modeling

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.
