摘　　要：大型公共建筑的制冷站中集中设置的冷水机组发热量较大,为保障冷水机组运行条件,避免制冷站内环境温度过高,需设置机械通风或者降温措施以消除室内余热。本文总结了大型制冷站常见的5种通风空调方案,对比分析了不同方案的适用场景。以某大型制冷站为例,分别按上述5种方案进行设计计算,并对各种方案能效进行计算分析,最终得出最优方案,为业界同行在研究此类问题时提供借鉴。The centralized chiller units installed in the refrigeration stations of large public buildings generate a large amount of heat.In order to ensure the operating conditions of the chiller units and avoid high ambient temperatures inside the refrigeration stations,mechanical ventilation or cooling measures need to be installed to eliminate indoor waste heat.This article summarizes 5 common ventilation and air conditioning schemes for large refrigeration stations,and compares and analyzes the applicable scenarios of different schemes.Taking a large refrigeration station as an example,design calculations were carried out according to the above five schemes,and the energy efficiency of each scheme was calculated and analyzed to ultimately obtain the optimal scheme,providing reference for industry peers in studying such issues.
