摘　　要：以济南某应用辐射供冷-贴附射流复合空调系统的会议室为模型,利用有限元数值模拟方法,对不同负荷分配比例下室内的热湿环境进行数值模拟。新风除湿过程中,伴随着空气湿度的降低,空气的温度必然也会受到影响,因此,存在一个新风除湿时所承担的最小显热负荷比例。对于本文研究的模型,经计算该比例为8.9%左右,以新风承担负荷比例10%为起点,将研究工况分为9种。研究结果表明,考虑室内热舒适性、空气品质和能耗等因素,辐射板承担的冷负荷比例控制在60%左右为宜。A meeting room which uses radiant cooling-attached jet hybrid air conditioning system in Jinan was simulated by the numerical simulation method of finite element to study heat and moisture environment on different load distribution. In the fresh air dehumidification process, accompanied by reduced air humidity, air temperature will be inevitably influenced, so there exist a minimum sensible heat load ratio that fresh air dehumidification assumed. For the models studied, the ratio is about 8.9% by calculating; to bear the load to the minimum fresh air ratio of 10% as a starting point, the study will be divided into nine kinds of condition. The cooling load that the radiant panel beard shall be controlled in 60%,considering indoor thermal comfort, air quality and energy consumption.
