【摘要】 应用能量和分析方法,对一种用于独立新风空调系统的新型水环热泵低温新风处理系统进行能量评价。通过实例对新风系统的能量和的传递与转换进行分析计算,并与采用冰蓄冷系统和冷水机组作为新风处理设备冷源的两种低温新风系统进行比较,结果表明采用水环热泵新风机组的独立新风处理系统,其能效比和效率较其它两种系统高,该系统良好的节能特性将有助于独立新风系统在我国的应用和推广。更多还原

【Abstract】 The energy and exergy analysis were applied to the energy evaluation for cold outdoor air handling unit of the new water loop heat pump,which is used in dedicated outdoor air systems(DOAS).The transfer and conversion of energy and exergy in DOAS were calculated and analyzed with an example,and comprised with the cold outdoor air-handling unit adopting ice storage system and water chilling unit.The results show that the energy efficiency ratio and exergy efficiency of DOAS adopting water loop heat pump outdoor air unit are higher than the other two systems.This good energy-saving characteristic will accelerate the application and popularization of DOAS.更多还原
