Energy and Cost Analysis of Hybrid Ground Source Heat Pump Systems for Hot and Humid Climate

This paper presents energy performance of hybrid ground source heat pump system used in a hotel building under a hot and humid climate condition. The performance data of a heat pump used in the building have been measured for several weeks. Based on the measured performance data of the heat pump, the building using a hybrid ground source heat pump system is first simulated using an energy simulation program. The building simulation model is then calibrated using monthly utility data. Finally, the calibrated building model using a hybrid ground source heat pump system is used to determine an economical effect of climatic and other factors to this building. The results are compared to those of the building using a conventional air source heat pump system and are used to find the advantage and disadvantage of a hybrid ground source heat pump system against a conventional system under a hot and humid climate condition.
