7.7 Process Water Use

7.7 工艺用水

English（英文原文）	中文（中文翻译）
Process water is used for building systems, such as cooling towers, boilers, and chillers. It can also refer to water used in commercial and industrial dishwashing, clothes washing, and ice making.	工艺用水用于建筑系统，如冷却塔、锅炉和冷水机组。它也可以指商业和工业洗碗、洗衣和制冰所用的水。
Process water can account for a significant amount of a building's water use. Most large buildings use sizable amounts of potable water for cooling towers, which release heat from air-conditioning systems through evaporation. Most process water does not need to be clean enough to drink, yet it is standard to use potable sources.	工艺用水可占建筑用水量的很大一部分。大多数大型建筑使用大量饮用水供冷却塔使用。大多数工艺用水不需要达到饮用水标准，但使用饮用水源已成为惯例。
Green Building Strategies	绿色建筑策略
Using ground-source heat pumps instead of cooling towers. Heat pumps release excess heat into the ground, saving water that would otherwise be evaporated for cooling.	使用地源热泵代替冷却塔。热泵将多余热量释放到地下，节省了原本用于冷却蒸发的水。
Metering water lost to evaporation during cooling tower use to implement water reduction strategies.	计量冷却塔使用过程中蒸发损失的水，以实施减少用水策略。
Maximizing the efficiency of cooling towers to reduce their water use.	最大化冷却塔的效率以减少用水量。
Selecting water-efficient appliances that use less water for other processes (e.g., laundry machines and dishwashers).	选择用水效率更高的设备，以减少其他工艺的用水量。
Investigating the feasibility of using alternative non-potable sources of water for some process water uses.	调查使用替代非饮用水源用于部分工艺用水的可行性。
