Summary

This study aims to investigate and compare the energy performance of an air source heat pump heating system and a radiant floor heating system with an energy recovery ventilator in an apartment building. The thermal load for a conditioned zone was derived using simulation tool TRNSYS 18, and the total energy consumption of the systems was calculated using an engineering-equation-solver (EES) for each component model. The coefficient of performance (COP) of the heat pump was calculated as 3.16, and the efficiency of the boiler in a radiant floor system was established as 0.9. The results indicate that the proposed system reduces energy consumption by 21.8% compared with the conventional floor heating system. The primary reason for this result is because the COP of the heat pump is dominant, even though the primary energy factor of electricity is 2.75.
