湿热地区实验室分功能的新风-补风系统的空调能耗分析

湿热地区设置空调的实验室的空调能耗比常规公共建筑的空调能耗要大得多，其中一个原因是空调系统中排风引起的空调新风能耗占比较大。本文提出了一种分功能独立的“新风-补风”系统，较大程度地减小湿热地区实验室所需的新风量和新风负荷，并结合实际案例分析该系统的节能效果。分析结果表明，与普通的“多联机+新风”空调系统相比，基于分功能设计的“多联机+分功能新风-补风”空调系统的节能率达到了65.8%。

An Energy Consumption Analysis of Air-conditioning System with Divided Function Fresh Air-Supplementary Air at Laboratories in Hot and Humid Areas

Laboratories with air-conditioning system in hot and humid areas consume much more air-conditioning energy than conventional public buildings. One of the most important reasons is that energy consumption from air-conditioning fresh air, caused by exhaust air, accounts for a large proportion of air-conditioning energy consumption in the laboratories in hot and humid areas. An independent fresh air-supplementary air system is proposed to minimize the fresh air volume and load from fresh air in the laboratories, and the energy saving effect of this system is analyzed in combination with a practical case. The results show that the energy saving rate of the "multi-split air conditioner + divided function fresh air-supplementary air" air-conditioning system based on the divided function design is up to 65.6%, compared with the conventional "multi-split air conditioner + fresh air" air-conditioning system.
