江苏徐州正在试点一项创新的集中供冷方案，利用关闭煤矿井水的恒定低温为居民住宅降温[1]。在最高气温超过35℃的情况下，试点小区内未开空调的室温可保持在26℃以下[1]。该系统通过地暖管网将恒定在19℃左右的矿井水循环输送，为建筑物提供制冷服务[1]。
相比传统空调，这一集中供冷方案的能耗降低约50%[1]。试点小区近百户居民每年可因此减少二氧化碳排放约50吨[1]。供冷费用按每平方米4元的标准按季度收取[1]。该项目试点成功后，当地计划推进大面积推广[1]。此外，济南中央商务区也实现了类似的集中供冷系统，其7台制冷机组可为约100万平方米的区域提供制冷服务[1]。
A residential community in Xuzhou, Jiangsu Province has launched a pilot program utilizing closed coal mine water to provide centralized cooling to residents. [1] The system leverages mine water that maintains a constant temperature of approximately 19°C, circulated through existing floor heating networks to cool living spaces. [1] During testing, when outdoor temperatures exceeded 35°C, indoor temperatures in the pilot community remained below 26°C without air conditioning in operation. [1]
The centralized cooling approach significantly reduces energy consumption compared to conventional air conditioning systems, cutting energy use by approximately 50 percent. [1] The pilot program covers nearly one hundred households, which collectively can reduce carbon dioxide emissions by around 50 tons annually. [1] Residents are charged a quarterly cooling fee of 4 yuan per square meter. [1] Following successful results from the pilot phase, local authorities plan to expand the system across a wider area. [1] Similar district cooling infrastructure has already been implemented in Jinan's central business district, where seven refrigeration units serve approximately one million square meters of cooled space.
