The Efficiency of Air Source Heat Pumps As A Reliable HVAC Option For Homes In Future Climate Scenarios Across Canada

This study investigates the use of air source heat pumps (ASHPs) in a detached residential home. The study aims to assesses the performance of ASHPs to see whether these systems can provide reliable and energy efficient heating and cooling in mild, cold, and very cold climate zones across Canada. This study also investigates how the use of ASHPs in a warming Canadian climate will affect residential TUEI and GHG emission compared to a natural gas furnace within the home. An energy model was constructed in OpenStudio to perform the necessary simulations to compare the ASHP and the natural gas furnace in present and future scenarios. Theoretical analysis was also done to determine whether the ASHP system can provide reliable heating and cooling to detached residential homes in Toronto (zone 6A), Vancouver (zone 5A) and Quebec City (zone 7). Findings indicated that ASHP systems would be best suited for residential use in Vancouver (zone 5A) across all three weather scenarios (Present 1998-2014, Future 2030-2041 and Future 2056- 2075) due to the milder temperatures annually. The colder climates for Toronto and Quebec City would require supplemental heating to meet the heating demand of the residence in those locations.
