摘要
结合既有空调系统的耗电量及当地采暖度日数,计算政府办公楼的全年能耗,进而提出该项目的改造方案为地源热泵与原有空调机组相结合的复合系统,该方案使得该办公楼每年节约标准煤8.48 kg/m2,运行费用每年节省22.2元/米2。
According to the power consumption of existing air-conditioning system and local heating degree days,the annual energy consumption of government office building is calculated.Then a complex system of ground-source heat pump and air-source heat pump is put forward as this project＇s reform scheme.It saves equivalent standard coal of 8.48kg/m2 and operating costs of 22.2 yuan/m2 each year.
