集中式空调系统能耗评价体系的研究

Energy evaluating system for central air conditioning systems

结合武汉地区的工程 ,给出了典型建筑当量满负荷运行时间 ,讨论了集中空调系统全年能耗计算方法和能耗评价体系 ,认为周边全年热负荷系数PAL、空调能耗因数CECAC是适合评价我国集中空调系统设计是否合理的有效能耗评价指标 ,但CECAC对基于计算负荷偏大所匹配的空调设备没有约束边界条件 ,建议尽快研究适合我国的PAL 。

With the projects in Wuhan, presents the operating hours of central air conditioning system under equivalent full load in typical buildings. Discuss several methods of calculating annual energy consumption and the energy evaluating system. Considers the peripheral annual load coefficient (PAL) and the coefficient of energy consumption for air conditioners (CEC AC ) as effective indexes for evaluating central air conditioning system design in China. But there is no constraint boundary conditions when CEC AC is used to evaluate the design induced by slightly-large calculation load. Suggests working out the PAL and CEC AC criteria suitable for our country as soon as possible.
