本文研究了三种显式空气冷却器:单级和多级间接蒸发冷却器，以及组合式冷却塔/热交换器空气冷却器。建立了关系式和性能特征。单级间接蒸发冷却器能够将进气冷却至接近进口湿球温度的温度。多级间接蒸发冷却器、热交换器/蒸发冷却器和冷却塔/热交换器空气冷却器都能够将进气冷却到接近入口露点温度的温度。在空调领域，性能系数的范围从单级间接蒸发冷却器的25到冷却塔/热交换器空气冷却器的75。 单位:双引文:研讨会，ASHRAE交易，1987年，第93卷，第。1，纽约州纽约市

This paper investigates three sensible air coolers: a single- and a multiple- stage indirect evaporative cooler, and a combination cooling tower/heat exchanger air cooler. Relations and performance characteristics are developed. The single-stage indirect evaporative cooler is capable of cooling inlet air to temperatures approaching the inlet wet-bulb temperature. The multiple-stage indirect evaporative cooler, the heat exchanger/evaporative cooler, and the cooling tower/heat exchanger air coolers are all capable of cooling inlet air to temperatures approaching the inlet dew-point temperature. In the region of air conditioning interest, the coefficients of performance range from 25 for the single-stage indirect evaporative cooler up to 75 for the cooling tower/heat exchanger air cooler.Units: Dual
