针对采用复合空调系统的办公室进行了CFD仿真,通过极差法和方差分析法得出了送风温度、送风速度、送风相对湿度、冷顶板表面温度及冷顶板占天花板面积比等参数对室内热舒适影响的主次关系,并对最显著的影响因素——送风速度的变化进行了动态模拟,分析了室内工作区和非工作区的温、湿度随时间的变化规律。结果显示,室内热湿状况再次达到稳态所需的响应时间长,不建议采用变风量调节方案;辐射冷顶板表面出现结露的可能性很小。
CFD simulation was carried out for the office with composite air-conditioning system, and the parameters of air supply temperature, air supply speed, relative humidity of air supply, surface temperature of cold roof and ceiling area ratio of cold roof were obtained by the method of range difference and analysis of variance Indoor and outdoor thermal comfort of the primary and secondary relationships, and the most significant factor - the air velocity changes were simulated, the indoor work area and non-work area temperature and humidity changes with time. The results show that the long-term response time needed to reach the steady state once again in the indoor hot and humid conditions is not recommended for variable air volume control. The possibility of condensation on the radiating cold roof surface is very small.
