Summary

Ground-source heat pump air conditioning systems are more efficient than air-source air conditioning systems in terms of energy consumption. Optimal hybrid utilization of air and ground heat sources has been shown to reduce the heat load on the ground. This study aims to ascertain the performance of hybrid heat pump systems in comparison to the standard air-conditioning system. A field test was conducted for the hybrid air conditioning and air-source systems. For the experiment, two commercial air conditioners were utilized. One of them was set up as a standard air-source air conditioner. Another one was connected with the ground to construct a ground-coupled hybrid air conditioner. The experimental setup was constructed in two small houses, one for each heat pump system. Generally, a hybrid heat pump system performs better over time compared to an air-source system. So, a comparison test between an air-source heat pump and a hybrid heat pump for cooling conditions was conducted to validate this point. The hybrid heat pump system showed an overall higher coefficient of performance (COP) compared to the air source air conditioning system.
