摘要
在我国长江流域 ,冬季具有室外气温高、空气相对湿度极大的特点。在这种空调负荷较小的情况下 ,笔者认为完全可以采用一种新型的空调方式———“辐射 +自然通风”。辐射方式的采用 ,降低了室内的空气温度 ;这样 ,使用自然通风也不会增加很多负荷 ;而自然通风的采用 ,会大大改善室内的空气品质。笔者从热负荷、舒适度、通风量、气流组织四个方面简单地论证了其可行性 ;并举例说明一个具体的系统方式及系统计算 ,分析了这种方式的优缺点及具体的适用范围 。
At the yangtze dranage area,it is quite high for the temperature and very big for the RH in the winter.As the heating load is small,a new type of air conditioning --'radiant heating+natural ventilation' may be applicable in this particular climate.According to the comfort index,it will acquire the same comfort that the internal radiant temperature rise while the total internal air temperature decrease as to the original.However,this can decrease the total heating load.In addition,RH of the internal air will be still in the comfort zone for the inlet natural air have the quite high RH that means no humidification will be needed. The feasibility of this new type of air conditioning was illustrrated from heating load,thermal comfort,ventilating volume and current distrbution.And an example was taken to show a simple but concrete system scheme and compute.In addition,the advantage and disadvantage of this sort of air conditioning and the applicable range was analyzed,then point out that it is suitable for two kinds of civil buildings-housing and office buildings which take up quite a portion of all buildings in modern cities.
