摘要：计算了夏热冬冷地区9个代表性城市典型办公建筑的空调设计冷热负荷和全年逐时负荷, 统计分析了不同工况下直燃机和空气源热泵2种冷热源设备的性能修正, 并对这2种冷热源设备构成的空调系统的全年运行能耗进行了模拟计算和对比分析。结果表明:由于夏热冬冷地区供冷需求和能耗的权重较大, 而直燃机空调系统全年制冷性能系数远低于空气源热泵空调系统, 所以该地区办公建筑以一次能源为基准计算的空气源热泵系统全年空调总能耗远低于直燃机系统。因此从节能上看, 选择空气源热泵更合理。

Energy consumption analysis of direct-fired absorption chiller and air-source heat pump for central air conditioning system of office buildings in hot summer and cold winter zone

(China Architecture Design & Research Group)

Abstract: Calculates the air conditioning design heating and cooling load and the annual hourly load of typical office buildings located in nine representative cities respectively in hot summer and cold winter zone.Statistically analyses the performance of direct-fired absorption chiller and air-source heat pump (ASHP) under different operating conditions.Simulates and compares the annual energy consumption of the air conditioning systems with the two kinds of cold and heat source equipment.The results show that the annual primary energy consumption of the air conditioning system with ASHP is much lower than that of with direct-fired absorption chiller in the office buildings in hot summer and cold winter zone, since the weight of cooling demand and cooling energy consumption is large in this area, and the cooling performance coefficient of the direct-fired absorption chiller system is much lower than that of the ASHP system.Therefore, from the perspective of energy saving, it is more reasonable to choose the ASHP system.
