Air-source heat pump for harsh, cold climates


From pv magazine global

Heating technology manufacturer Carrier is set to start field testing its prototype air-source heat pump for cold climates.

The project is part of the “Cold Climate Heat Pump Challenge” developed by the U.S. Department of Energy. It aims to develop and commercialize a new heat pump technology to more efficiency heat residential homes in climates with freezing temperatures.

Heat pump prototypes participating in the project must perform efficiently at temperatures equal or below negative negative 20 degrees Fahrenheit. They are designed to be grid-interactive, provide high-efficiency heating performance in harsh climates, and employ environmentally friendly refrigerants.

The prototype heat pump first underwent a lab testing phase, with results allowing it to pass to the field-testing phase.

“We’re pleased with the lab performance of our prototype heat pump and the final test results,” said Justin Keppy, president, North America residential and light commercial HVAC at Carrier. “Our team of dedicated engineers and product managers are hard at work continuing to develop next generation heat pumps to increase efficiency, save consumers money and benefit the environment.”

Carrier joins Irish-based Trane Technologies and U.S.-based Lennox heat pump manufactures in developing prototypes entering the field-testing phase. Other manufacturers participating in the project include Bosch, LG, and Daikin. Commercialization of the successful units is expected by 2024.
