摘要
通过分析直接蒸发冷却(direct evaporative cooling,DEC)空调系统能效比(energy efficiency ratio,EER)对室外气象参数变化的敏感度,发现DEC空调系统的累年平均能效比和额定能效比均无法作为直接蒸发冷却空调设计依据。以乌鲁木齐地区为研究对象,构建并给出了用于评估DEC空调系统性能的典型气象季。结果表明,DEC气象季可准确地反映直接蒸发冷却空调制冷能力随室外气象参数变化的特征,并且由典型气象季计算出的平均和最小能效比可分别作为DEC空调系统的经济评价指标和设备选型的关键依据。
This paper analyzed the sensitivity of energy efficiency ratio(EER)of direct evaporative cooling(DEC)air-conditioning system to the changes of outdoor meteorological parameters.It shows that the annual average EER and the rated EER of DEC air-conditioning are not suitable.Therefore,we constructed a typical meteorological season for evaluating the performance of DEC air-conditioning system and took Urumqi as subject.The results show that the proposed DEC meteorological season can accurately reflect the characteristics of refrigeration capacity changing with the outdoor meteorological parameters.The average and minimum values of EER calculated in the typical meteorological season can be used as the key basis for local economic evaluation and equipment selection of DEC air-conditioning system,respectively.
