Summary

The importance of energy conservation has greatly increased to promote the decarbonization of buildings. This has resulted in significant interest in variable-speed heat pumping systems with improved efficiency. This paper formulates and evaluates a variable heat pump system model compatible with Building Energy Modeling (BEM) software like EnergyPlus. The model uses as inputs the indoor and outdoor temperatures along with indoor supply air and compressor speed of the heat pump system to predict the heating capacity and coefficient of performance (COP) with 10 trained coefficients each for capacity and COP prediction. The model predictions are compared against experimental data from two, state-of-the-art, variable-speed heat pumps. The model can predict the capacity and COP of the variable heat pump system under 3.5% Mean Absolute Percentage Error (MAPE).
