摘要
在楼宇空调水系统设计中,冷水机组的冷水供、回水温差通常为5℃。近年来冷水机组的效率提高很快,同时大温差小流量的空调水系统方案受到了更多关注。本文分析说明大温差小流量的空调水系统方案经过优化可以减少空调系统的总能耗和配套设备的初投资,探讨在该方案中末端设备的选择问题,并结合工程实例说明该方案的应用效果。
The chilled water temperature difference between inlet and outlet of chiller is ususlly 5℃ in traditional design. As chiller efficiency is highly improved in recent years, the HVAC water system proposal of big temperature difference with small water flow rate is more concerned. The proposal optimization to decrease the operation cost and primary cost has been analyzed, its influence on the choice of water system terminals has been discussed, and the application results with engineering examples have been listed.
