水温控制精度对蒸发式冷气机制冷量测量准确度的影响研究

Influences of Water Temperature Control Accuracy on Measurement Precision of Cooling Capacity of Evaporative Air Cooler

水蒸发冷却制冷设备性能的好坏直接关系到可再生低品位能源"干空气"能的推广和应用,本文对《蒸发式冷气机》(送审稿)中水温控制精度范围的不合理性进行了分析,对不同喷淋水温度对蒸发冷却制冷量测量准确性的影响进行了探讨,结合实验室测试检验要求和标准中制定的满足水蒸发冷却设备制冷量合格判据的要求,给出了应达到的喷淋水温度范围。

The application and extension of renewable low-grade energy of dry air is directly affected by the performance of water evaporative cooling appliances.In this paper,the unreasonable control accuracy range of water temperature in the standard of Evaporative Air Cooler（draft version for examination） was analyzed,the influences of different spray water temperatures on measurement precision of cooling capacity of this type of equipment was discussed.Furthermore,combined with the requirements of testing inspection and the reasonable criteria to satisfy the equipment cooling capacity presented in the standard,the suitable range of spray water temperature was given out.
