摘要
本文对上海某小型办公建筑空气源热泵空调系统制冷及制热工况全年性能进行了实验研究,研究结果表明,空气源热泵空调系统在夏热冬冷地区能够满足建筑的制冷及制热需求,为建筑提供全年均匀稳定的热环境。同时,该空气源热泵空调系统可以根据建筑的冷/热负荷调节其制冷量以及制热量;在制冷工况下,室外温度越高其制冷量越大;在制热工况下,室外温度越低其制热量越大。此外,本文还提出了一种以循环效率-机组负载率曲线来表征系统运行性能的方法,该方法可以方便直观地表现热泵机组在变工况、变负荷情形下的性能变化特性。
bIn this paper, the annual performance of an air-source heat pump air conditioning system in cooling and heating conditions is investigated in an office building in Shanghai. The results show that the air-source heat pump air conditioning system could satisfy the cooling and heating demand of the office building, and it could provide a uniform and stable indoor environment condition all year. Meanwhile, this system could adjust cooling/heating power with building load; the system can provide more cooling power at higher outdoor temperature in cooling conditions and more heating power at lower outdoor temperature in heating conditions. Moreover, a method is proposed to evaluate the system performance by cycle efficiency curve and load rate of heat pump, which can directly show the performance of heat pump under different conditions and loads.
