C08 -- Field Performance and Life Cycle Analysis of Cold Climate Heat Pumps Using Lower GWP Refrigerant ✓ Most Recent

This paper compares the performance of a cold climate air to air heat pump that uses R-410A refrigerant with one that uses the lower global warming potential refrigerant R-454B. The analysis is based on controlled field measured performance of two cold climate heat pump systems tested at the Canadian Centre for Housing Technology located in Ottawa, Canada. It compares the measured capacity and coefficient of performance of these systems under identical load conditions and includes a life cycle analysis of the embodied carbon, upstream and operational emissions associated with the operation of the systems.
