夏热冬冷地区某三甲医院空调制冷机房运行性能实测研究
Field test and study on operation performance of air conditioning and refrigeration machine rooms of a tertiary hospital in hot summer and cold winter zone
摘要：
医院建筑夏季供冷需求高,实现制冷机房高效运行具有显著的节能减排效益。以夏热冬冷地区某三甲医院为研究对象,通过对其空调制冷机房在夏季的运行性能进行实测研究,总结出冷水机组运行负荷率偏低,蒸发器与冷凝器换热性能不佳,冷水、冷却水系统缺乏合理调控导致的大流量小温差等问题,并提出了优化措施。研究结果旨在为同类建筑制冷机房节能运维提供建议。
Abstract：
Hospital buildings have high cooling demand in summer, and the efficient operation of the refrigeration machine room has significant energy-saving and emission-reduction benefits. Taking a tertiary hospital in a hot summer and cold winter zone as an example, through the field test and study of the operation performance of its air conditioning and refrigeration machine rooms in summer, the problems of low operation load rate of chillers, poor heat exchange performance of evaporator and condenser, and large flow and small temperature difference caused by lack of reasonable regulation of cold water and cooling water system are summarized, and optimization measures are proposed. The research results aim to provide suggestions for the energy-saving operation and maintenance of refrigeration machine rooms in similar buildings.
