摘要
分析了冷冻水管沿地铁区间隧道敷设时与周围环境的换热状况;认为采用集中供冷的方式,在隔热情况下可不考虑冷冻水因长距离输送而引起的温升损失。
After a discussion of the heat transfer condition of the chilled water pipe which is installed in a tunnel, the relation between the temperature of the chilled water and its transportation distance, the author holds that a central refrigeration system shall be adopted, and the loses of chilled water temperature in a long transportation distance could be overlooked on the condition that the pipe is heat insulated.
