摘要
This paper develops previous research on passive house (PH) space heating. A simple and accurate ground heat exchanger model is developed. It is based on a numerical transient bi-dimensional approach that allows to computing the ground temperature at the surface and at various depths. The new model was integrated into the existing theoretical approach and implemented within the computer code used to simulate the heating system operation in Pirmasens PH (Rhineland Palatinate, Germany). The heating and cooling potential of the system under real climatic conditions was investigated. The energy delivered by the ground heat exchanger depends significantly on different design parameters like pipe's depth, diameter and material. (c) 2006 Elsevier Ltd. All rights reserved.
