Abstract The coefficient of performance (COP) of an air source heat pump represents its energy efficiency, and it is common to use a constant value for convenience. However, using an average COP for comparing energy consumption does not consider the actual operating environments, leading to limitations in accuracy. In this study, we applied both a linear first-order function model and a quadratic second-order function linearization model to the annual average and variable COPs of air source heat pumps in residential buildings. Through a simulation-based case study, we analyzed the impact of the COP of air source heat pumps on the annual energy consumption and energy costs in residential buildings.
