摘要:
公共建筑的电耗已接近城市建筑电耗的50%，而空调能耗占建筑能耗的33%～45%.大空间是公共建筑的特点，减少大空间的能耗是降低公共建筑能耗的关键.大空间按照规范设计一般是采用全空气空调系统，为了提高大空间节能效果，应针对不同大空间采用不同空调系统.对于体型复杂，空间大小不规则，空间高度大于5 m以上的大空间仍采用常规一次回风（无再热）全空气系统；对于体型比较规整，房间吊顶净高在4 m左右的大空间宜采用新风换气机加风机盘管空调系统.通过对武汉450 m2大空间，净高4 m的办公室应用新风换气机加风机盘管系统的夏季工况分析，对照常规一次回风（无再热）全空气系统，证实新风换气机加风机盘管系统节能效果显著，全热回收装置节能42.84%，且当室外设计参数朝着温度降低、相对湿度增加的方向变化时，节能效果及室内参数将朝着有利于全热回收的方向发展.
Abstract:
The electricity consumption of public building has almost reached 50% electricity consumption of city building, and the air\|conditioning energy consumption reaches 33% to 45% of building energy consumption. Large space is the common feature of public building, so reducing energy consumption in large space is the key to drop energy consumption of public building. Large space normally utilizes all\|air air conditioning system according to the code of design. To improve the energy saving effect in large space, various air\|conditioning system should be applied when facing different types of large space. In case of the large space with complicated shape, irregular space and the height of space over 5 m, the normal all\|air primary return air system(without re\|heating) should be applied; in case of the large space with regular shape and clear room height of approximately 4 m, the fresh air exchanger plus fan\|coil\|air\|conditioning system is preferred. Furthermore, through analyzing the summer working conditions of fresh air ventilator and primary fan coil system in a spacious office with clear height of 4 m and area of 450 m2 at Wuhan, the combination of fresh air ventilator and primary fan coil system is proved to have significant effect on saving energy: the energy savings of total heat reclaim unit is 42.84%. Furthermore, when outdoor design parameters changes toward the direction of lowering the temperature and increasing the relative humidity, the efficiency of saving energy and indoor parameters will become more beneficial towards the total heat reclaim model.
