夏季湿热地区置换通风和冷却顶板复合系统节能潜力研究
Energy saving potential of a combined cooling ceiling and displacement ventilation system in hot and humid climate zones in summer
摘要：
根据上海一办公楼置换通风和冷却顶板复合系统的设计及运行特点，应用EnergyPlus软件模拟了采用转轮除湿方式的复合系统的供冷季能耗，并分别模拟了采用冷却除湿方式的复合系统、带热回收装置的混合通风系统和置换通风系统的供冷季能耗以进行对比。结果表明，在湿热地区采用转轮除湿方式可比冷却除湿方式节约制冷机冷量，空调季总能源费用比混合通风系统节约30%左右。
Abstract：
Based on the design and operation characteristics of the combined system in an office building in Shanghai, simulates the energy consumption of the system with rotary dehumidification during cooling season using the EnergyPlus software. To evaluate the system performance and energy saving potential, other three systems—the combined system with cooling dehumidification, mixing ventilation system and conventional displacement ventilation system with heat recovery devices—are simulated. The results indicate that the combined system with rotary dehumidification consumes less energy for cooling than that of the system with cooling dehumidification in hot and humid climate zones, and total energy costs can be reduced by about 30% compared with the mixing ventilation system during cooling season.
