摘要
在某办公楼中庭采用常规全空气空调系统和温湿度独立控制空调系统(THIC)2种方案时,对室内的空调冷负荷及对应的送、回风参数进行计算和对比,进而对室内气流组织的差异进行模拟分析,并从热舒适性、空气品质等角度对模拟结果进行讨论。结果显示,采用THIC空调方式比常规全空气空调系统的室内气流速度场、温度场更加均匀,人员活动区域的热舒适、空气品质更好,而且可以显著降低高大空间的空调区域,相对于常规全空气空调系统,可降低空调冷负荷25%左右。
Presents the comparison of the cooling load and the parameters of the supply and return air on an office building between conventional all-air air-conditioning system and temperature and humidity independent control（THIC） air-conditioning system. Then, carries out the simulation of air distribution. Gives the simulation results analysis from thermal comfort and indoor air quality angle. The results show that the THIC air-conditioning system has better indoor air velocity field and temperature field than the conventional air-conditioning system, especially in the people moment area. In addition, the air-conditioning area can be significantly decreased,in order to save more than 25 % of the air-conditioning energy consumption compared to the conventional all-air air-conditioning system.
