摘要
运用喷淋降温技术对广州市某大型三甲医院住院楼的老旧中央空调风冷式机组开展节能改造,记录并比较空调机组采用喷淋降温技术前后的主要性能参数、机组用电量等数据,分析使用喷淋降温技术的效果。采用喷淋降温技术的空调机组近2年共节省用电量65.6万kWh,节约消耗265.02吨标准煤,减排二氧化碳642.88 t。喷淋降温技术在一定程度上能够提高老旧中央空调机组的制冷能力与能效,为医院开展中央空调节能降耗探索工作提供参考。
The energy-saving renovation of the old central air-conditioning air-cooled unit in the inpatient building of a large third-class hospital in Guangzhou was carried out by using the spray cooling technology,and the main performance parameters and unit power consumption of the air-conditioning unit before and after the use of the spray cooling technology were recorded and compared to analyze the effect of the spray cooling technology.The air-conditioning unit has saved a total of 656000 kWh of electricity in the past two years,which is equivalent to saving 265.02 tons of standard coal consumption and reducing carbon dioxide emissions by 642.88 t.Spray cooling technology can improve the refrigeration capacity and energy efficiency of old central air conditioning units to a certain extent,it is provide a reference for the exploration of energy saving and consumption reduction in central air conditioning.
