基于长期运行特性的地源热泵系统设计方法

n optimal ground source heat pump (GSHP) system assures a problem-free operation over the entire life cycle, proper design method for the GSHP system is crucial. Different from traditional design methods, the presented method is modified by the long-term performance of a practical GSHP system, which is directly reflected by continuous temperature change of the ground, the ground thermal properties and other influential factors. Theoretically the operation of designed GSHP is simulated based on degree-day boundary conditions and building loads during the periods of ten years. Continuous experiment validation on the practical GCHP system has been carried out among the years of 2003 to 2007, using a computer data acquisition system. Through the comparison between experimental data and simulated results, the optimum design method of GSHP system is verified in practice.
