摘要

本文提出一种与露点间接蒸发冷却器相耦合的冷库用新型空气制冷循环。对该新型循环进行了相应的热力计算，与普通空气制冷循环及NH3蒸气压缩循环进行了对比分析，并对比分析了工况参数变化对耦合露点间接蒸发冷却器前后的空气制冷循环性能及NH3蒸气压缩循环COP的影响。结果表明：配置露点间接蒸发冷却器的新型空气制冷循环的性能得到了提高，设定工况下最大COP可提高37.8%，且相比NH3制冷循环，流程与设备更简单。

Abstract

A new type of air refrigeration cycle combined with a dew-point indirect evaporative cooler (IEC) is proposed. Corresponding thermodynamic calculations on the new cycle were carried out. A comparative analysis was carried out with the ordinary air refrigeration cycle and NH3 vapor compression cycle. The influences of operation conditions on the performances of the air refrigeration cycle before and after combining the dew-point IEC as well as the COP of the NH3 vapor compression cycle were analyzed. The results showed that the performance of the new air refrigeration cycle combined with the dew-point IEC was greatly improved. The maximum COP can be increased by 37.8% under the design conditions. In addition

compared to the NH3 refrigeration cycle

it can operate with simpler processes and equipment.
