辐射供冷/供热+独立调湿新风空调系统在办公建筑中的应用

Application of air-conditioning system of radiant cooling/heating & fresh air humidity independent control into office buildings

办公建筑常规空调系统采用热湿耦合处理方式,不能很好地适应室内热湿比的变化,且存在能耗高等问题。辐射供冷/供热+独立调湿新风空调系统可以很好地适应室内热湿比的变化,将室内温湿度控制在更加舒适的状态,同时运行更节能。本文对上海某办公建筑空调系统进行分析,当采用辐射供冷/供热+独立调湿新风空调系统时,可利用高温冷水降温、干燥新风除湿,节省运行能耗近30%。

Traditional air-conditioning systems of the office buildings usually use the heat-moisture coupling treatment method,which can not adapt well to the changes of indoor heat-moisture ratio and has issues such as high energy consumption.The air-conditioning system of radiant cooling/heating&fresh air humidity independent control can adapt well to the changes of indoor heat-moisture ratio,make the indoor temperature and humidity more comfortable,and save more energy consumption.Based on the air-conditioning system of one building in Shanghai,using the air-conditioning system of radiant cooling/heating&fresh air humidity independent control,the temperature is reduced with high-temperature chilled water,the dry fresh air is used for dehumidification,and the energy consumption is saved nearly by 30%.
