摘要/Abstract

摘要： 对于热负荷占优的建筑气候区,年复一年的冬夏负荷不平衡会导致土壤源热泵机组的能效比COP (Coefficient of Performance)越来越低。过渡季节利用地埋管进行太阳能跨季节蓄能可有效地解决土壤热平衡问题。以一个实际工程为支撑,开展了跨季节蓄能的实践,并基于TRNSYS16模拟软件对过渡季节的蓄热过程进行模拟,结合实验数据验证了模型正确性并对模拟结果进行修正。结果表明,模拟数据与实测数据非常接近;过渡季节进行太阳能跨季节蓄能是可行的。

Abstract: The COP (Coefficient of Performance) of the GSHP system has decreased gradually year after year caused by imbalance energy loads especially in heating-dominated climate zones. The solar thermal energy storage system in transition season can solve the problems effectively. The practice of solar seasonal storage was carried out and supplied by a practical project. TRNSYS 16 was used to simulate the solar energy storage experiment process. The correctness of the model was verified by the experimental data and the simulation results were corrected. Results shows that the simulated results and the measured data were well matched with each other and it is feasible to perform the solar thermal energy storage process in transition season.

Key words: GSHP system, seasonal solar energy storage, TRNSYS simulation, transition season
