於區域供冷系統中使用循環再用水 區域供冷系統將中央供冷站制造的冷凍水通過地下冷凍水管道 網絡輸送給多個建築物以滿足其製冷量需求。新發展區將逐 步使用更多區域供冷系統，作為需要使用大量食水的非飲用用 途，尤其是無法使用海水為水源的蒸發式製冷系統。為配合香 港的可持續發展，一項諮詢研究已於二零二二年九月展開， 探討於蒸發式區域供冷系統中使用循環再用水以節省食水在技 術及經濟方面是否可行。 Use of Recycled Water in District Cooling System in Hong Kong District cooling system (DCS) distributes chilled water through a network of underground pipes from central chiller plant to multiple buildings for air-conditioning. DCS will be increasingly adopted in new development areas as one of the non-potable applications using substantial amount of fresh water, in particular for DCS of evaporative type when seawater supply source is not available. To support sustainable development of Hong Kong, a consultancy study was has commenced in September 2022 to investigate into the technical feasibility and financial viability of pioneering the use of recycled water in DCS of evaporative type for conserving fresh water resources. 水務署 二零二二至二三年年報 WSD Annual Report 2022/23 38 Scale up 升 級 開 拓
