Four more pass cold climate heat pump challenge

USA: The US Department of Energy (DOE) has announced that a further four manufacturers, Bosch, Daikin, Midea, and Johnson Controls, have passed its cold climate heat pump challenge.

Launched in 2021, the DOE’s Residential Cold Climate Heat Pump (CCHP) Technology Challenge seeks to accelerate the deployment of heat pump technologies by supporting innovation and manufacturing. It brings together public and private sector stakeholders to address technical challenges and market barriers to their adoption. 

Having successfully produced heat pump prototypes, Bosch, Daikin, Midea, and Johnson Controls will join previously announced partners Lennox International, Carrier, Trane Technologies, and Rheem in the next phase of the Challenge. This phase will involve the installation and monitoring of more than 23 prototypes in various cold-climate locations throughout the US and Canada over the next year. 

The DOE is now turning to the nearly 30 state, utility, and other partners that were part of the original challenge commitments to encourage the adoption of CCHPs. The DOE says it will continue to work with partners to develop programmes, incentives, education and outreach campaigns that help consumers better understand the benefits of these new designs.

The Challenge specifies that prototypes deliver 100% heating capacity without the use of auxiliary heat and with significantly higher efficiencies at 5ºF (-15ºC).
