Résumé

Nowadays, ground source heat pump (GSHP) are attracting attention as an energy saving technology in cooling and heating systems. The objective of this study is to evaluate the performance of a GSHP that uses the direct expansion method, in cooling and heating air conditioning applications. This pump utilizes the steel pipe foundation pile of the house to accommodate its heat exchanger. To achieve the same, 12 underground heat exchangers were inserted into the foundation piles. Experiments were conducted to study its performance in both cooling and heating operations, and the coefficient of performance (COP) was obtained by measuring the amount of heat transferred and the electricity consumption for running the GSHP. From the experimental result obtained, the COP was approximately 4.0 in the cooling operation and approximately 4.8 in the heating operation. Additionally, no performance deterioration was observed in the intermittent cooling or heating operation for 5 days.
