STUDY ON AN ENERGY PILE SYSTEM FOR AIR CONDITIONING : Application to an actual building and evaluation on space heating performance

This paper describes field performance of air conditioning with an energy pile system, which was applied to pile foundations of an actual building, for the purpose of the cost reduction of an underground heat exchanger. Firstly, the building for both office and residential use, for which a space heating and cooling system using friction piles was installed, was built in Sapporo in December, 2000. Secondly, three tests were carried out in order...
