描述了一种使用干燥剂轮、紧凑型间接蒸发冷却器和小型空气-空气热交换器开发的冷却系统。该系统无需通过除湿轮进行深度除湿，并为空调空间提供25%至35%的通风空气。使用一个直径为0.68米（27英寸）、深度为0.2米（8英寸）的1M型干燥剂转轮，在175摄氏度（347华氏度）下再生，可实现15.0千瓦（4.3吨）的冷却，热性能系数（COP）为0.72。通过添加直接蒸发冷却器，系统可以提供大范围的湿度控制。美国正在开发的设备的总制冷系数预计将超过0.9。关键词:1997年，干燥剂，冷却，蒸发冷却，性能系数，通风，空调，除湿引用:研讨会，ASHRAE Trans。1997年，第103卷，第一部分

Describes a cooling system developed using a desiccant wheel in conjunction with a compact indirect evaporative cooler and a small air to air heat exchanger. The system eliminates the need for deep dehumidification by the desiccant wheel and provides 25% to 35% ventilation air to the conditioned space. Using a 0.68 m (27 in) diameter by 0.2 m (8 in) deep type 1M desiccant wheel regenerated at 175degC (347degF), 15.0 kW (4.3 tons) of cooling were achieved with a thermal coefficient of performance (COP) of 0.72. With the addition of a direct evaporative cooler, humidity control over a broad range can be offered by the system. States equipment under development is expected to exceed a gross cooling COP of 0.9.KEYWORDS: year 1997, Desiccants, cooling, evaporative cooling, coefficient of performance, ventilation, air conditioning, dehumidifying
