Bilan frigorifique d'un système à pompe à chaleur sol-eau.

Ground heat balance in GSHP.

Auteurs : MA H., LONG W.

Résumé

For its energy saving and environmental protection advantages, ground source heat pump (GSHP) system developed very quickly in China in recent years. From living buildings to office buildings, GSHP systems become larger and larger. But in most places, the energy which GSHP systems puts into the ground in summer and extracts from the ground in winter is not equal. Then the ground heat balance becomes a key factor for the long-term steady running of the GSHP system. This article introduced probable ground temperature changes in different climate zones, analysed an actual project earth temperature change over one year, and presented a design method based on an accurate ground source response test, uses assistant refrigeration or heating equipment to assume peak load, combines GSHP in a composite system, at the same time maintains a minimum distance between different geothermal heat exchanger, to assure a successful application of GSHP system in a large-scale building.
