Partner: National Renewable Energy Laboratory

NREL has partnered with ComEd to research the technical aspects and potential energy savings of high-efficiency variable-speed air-source heat pumps in cold climates.

Overview

Recent technological advances in variable-speed compressors and electronically commutated fan speed modulation allow some modern heat pumps to operate efficiently in more extreme temperatures than traditional models.

Through laboratory testing, NREL will map the expected performance of ducted split heat pump systems under steady-state conditions to determine the coefficient of performance and unit capacity across a range of modes and conditions. This data will then be used to develop performance curves that accurately represent how this technology would perform in the ComEd service territory.
