寒冷地区学校建筑空调系统设计

Design of air-conditioning system for school building in cold regions

介绍寒冷地区学校建筑空调系统运行时间、空调负荷组成、冷热源选择等。寒冷地区学校建筑在非供暖季空调制热需求仍大于制冷需求,建议空调系统冷热源选用冷暖型。在空调系统设计过程中,应根据当地负荷特点选取新风设计参数,选择合适的新风设备。由于冬季新风负荷占比较大,建议选用带热回收功能的新风机组。

The running time,the composition of air-conditioning load and the selection of cold and heat sources for school buildings in cold regions are introduced.In non-heating seasons,the school buildings still need more air-conditioning heating than cooling,so cold warm type should be recommended for the cold and heat sources of air-conditioning system.In the design process of air-conditioning system,the design parameters of fresh air and fresh air equipment should be selected according to the local load characteristics.Due to the large proportion of fresh air load in winter,it is recommended to select fresh air handling unit with heat recovery function.
