Résumé
Air source heat pumps can be used as an alternative to natural gas furnaces in efforts to reduce annual heating energy consumption and greenhouse gas emissions. However, in cold climates, the performance of air source heat pumps can be affected by frost formation on the evaporator surface. The performance reduction will in turn lead to an increase in energy consumption and greenhouse gas emissions. This paper aims to quantify the effect of frosting on the performance, energy consumption and greenhouse gas emissions of natural gas driven air source heat pumps called gas absorption heat pumps (GAHPs) in eight different Canadian cities.GAHPs experienced between 1%-2% increase in energy consumption due to frosting across the 8 different Canadian cities. In comparison, electric air source heat pumps (ASHPs) may experience up to 20% increase in energy consumption. Therefore, GAHPs could be a potential replacement for natural gas furnace heating, over ASHPs, in cold climates (where frosting is a prevalent problem).
