温和地区采用大温差空调系统的技术经济分析

Technical and Economic Analysis of Air-conditioning Water System Using Large Temperature Difference in Temperate Regions

在温和地区的气候条件下和特定的使用功能要求下，分析比较了空调水系统采用大温差和常规温差对于风机盘管﹑新风和空气处理机组﹑冷水机组﹑冷冻冷却水泵﹑冷却塔﹑空调热水泵等设备运行工况的影响，认为对本项目最适宜的选择是空调冷水5∽12℃、热水60∽45℃，冷却水28∽36℃。

Under the climatic condition of temperate regions and the requirement of specific use, The effect of using large temperature difference and conventional temperature difference in air conditioning water system on the operating conditions of fan coil, fresh air and air handling units, water chiller, cooling tower, chilled water pump, cooling water pump and air conditioning heat pump and other equipments were analyzed and compared. It is considered that the optimum temperature difference is 5∽12℃for air conditioning cold water, 60∽45℃for heat water and 28∽36℃for Cooling water, respectively.
