摘要
介绍了该地源热泵项目的热响应测试情况,在此基础上开展了控制策略研究,对地埋管优先、冷却塔优先和优化控制三种方案下的全年运行工况进行了模拟。研究表明,通过优化控制,系统运行1a后,土壤温度升高0.28℃,夏季最高排热温度为32℃,冬季最低取热温度为8℃,满足设计要求。
Presents the thermal response test of the ground-source heat pump project. On this basis, develops the research on control strategies. Simulates year-round operating conditions of the three strategies of the ground heat exchanger in priority, cooling tower in priority and optimization control. The research indicates that by using the optimization control strategy, the soil temperature increases 0.28 ℃at the end of one year operation, the maximum temperature of heat charging in summer is 32 ℃ and the minimum temperature of heat discharging in winter is 8 ℃, meeting the design requirements.
