基于能量和㶲分析的方法对2种传统型和2种改进型蒸发冷却新风空调器(FAC)进行对比;将各FAC和机械蒸汽压缩空调(MVC)组成4种不同的蒸发冷却复合空调(HAC),对其节能性进行对比分析。首先,建立喷淋填料和翅片式表冷器的分布式参数模型以及MVC的关联式模型,并对喷淋填料和翅片式表冷器的数学模型进行验证。其次,研究4个独立参数(环境空气温度、含湿量、新风质量流量和传热单元数)对各FAC的性能系数(COP)、㶲效率和㶲效比的影响以及对各HAC节能率的影响。最后,评估4种HAC在气候干热的吐鲁番的夏季季节性节能潜力。研究结果表明:各FAC的㶲效率和㶲效比随环境空气温度增加而升高,随新风质量流量的增加而...

Based on energy and exergy analysis methods, two traditional and two improved evaporative cooling fresh air conditioners(FAC) were compared. Moreover, each FAC was combined with a mechanical vapor compression air conditioner(MVC) to form an evaporative cooling hybrid air conditioner(HAC), and the energy saving of the four HACs was analyzed and compared. Firstly, the distributed-parameter models of the packed cooling tower and finned coils, and the correlation model of the MVC were established. The mathematical models of the packed cooling tower...
