摘要

本文利用由焓差室控制环境参数的水-水蒸发式冷却换热器实验台，研究了喷淋密度、迎面风速和环境参数对其传热传质性能的影响。当改变喷淋密度和迎面风速时，测得最佳喷淋密度为0.0314 kg/（m?s)，最佳迎面风速为3.22 m/s；在最佳喷淋密度和最佳迎面风速的条件下，改变环境参数，测得湿球温度从22 ℃上升至28 ℃时，总传热系数降低约4.2%，传质系数降低约9.3%；相对湿度从85%降低至55%时，总传热系数上升约10%，传质系数上升约13.7%。

Abstract

The experiment rig of evaporative cooling heat exchanger is set up for experimental research and the environmental parameters were controlled in enthalpy difference laboratory in this paper. The influences of spray density

face velocity and environmental parameters on the performance of evaporative cooling heat exchanger were experimentally investigated. The optimal spray density and face velocity were found

which were 0.0314 kg/(m?s) and 3.22 m/s respectively. In addition

the heat transfer coefficient would decrease by 4.2% and the mass transfer coefficient would decrease by 9.3% when the wet bulb temperature was increased from 22 ℃ to 28 ℃; the heat transfer coefficient would increase by 10% and the mass transfer coefficient was increased by 13.7% with the relative humidity of inlet air decreasing from 85% to 55%.
