基于干燥剂轮的空调系统（DWAC）包括一个干燥剂轮组件，该组件执行与另一个组件耦合的潜在冷却，例如间接蒸发冷却器（IEC也称为露点蒸发冷却器），该间接蒸发冷却器在不向气流中添加水分的情况下执行显式冷却。由于热再生气流带走热量并释放°F吸附热，干燥剂转轮中的水分去除几乎是绝热的。这种对干燥空气的加热是不必要的，不仅会降低系统的显热和潜在冷却性能，而且还需要高温的再生空气来驱动干燥剂轮在炎热潮湿的气候下工作。 理想情况下，干燥剂转轮的除湿过程是等温的，而不是绝热的。因此，在这里，我们提出了一种内冷式除湿轮的设计方案，该方案可实现近乎等温的除湿，然后使用数学模型分析包含该部件的完整DWAC系统的性能。新设计使用78.8°F（26°C）的冷却水作为干燥剂轮的冷却源，以减少吸附热和携带热对温度的影响。然后采用一个经过内冷式干燥剂转轮和商用间接蒸发冷却器实验数据验证的模型来评估DWAC系统的性能。结果表明，在进气温度为95°F（35°C）和相对湿度为60%的情况下，建议的带有内冷式干燥剂转轮的DWAC系统至少可以吸附0。 当再生空气温度为140°F（60°C）时，与使用绝热轮的DWAC系统相比，每秒增加0053lb（2.4g）水分（每2.2lb（1kg）干燥空气），这可以很容易地从太阳能集热器获得。此外，内冷式干燥剂转轮系统的电气系数°F性能计算为7至13，而绝热转轮系统的电气系数为5.2至8.2。这些结果表明，在炎热潮湿的气候条件下（干球温度为95°F（35°C），相对湿度为60%），带内冷轮的DWAC系统的效率将是最高效的分体式空调的两倍，是2014年澳大利亚市场平均温度°F的三倍。 引用:2018年年度会议，德克萨斯州休斯顿，会议论文

Desiccant wheel based air-conditioning systems (DWAC) include a desiccant wheel component that performs latent cooling coupled to another component, for example an indirect evaporative cooler (IEC also known as a dew point evaporative cooler), that performs the sensible cooling without adding moisture into the air flow. Moisture removal in the desiccant wheel is approximately adiabatic due to heat carryover from the hot regeneration air stream and release °F adsorption heat. This heating °F the air being dried is unwanted and cannot only decrease both the sensible and latent cooling performance °F the system but also requires a high temperature °F regeneration air to drive the desiccant wheel to work in hot and humid climate. Ideally the moisture removal pr°Cess for desiccant wheel would be isothermal instead °F adiabatic. Thus, here we propose an internally cooled desiccant wheel design that °Ffers nearly isothermal dehumidification and then use a mathematical model to analyze the performance °F a complete DWAC system incorporating this component.The new design uses 78.8°F (26°C) cooling water in the pr°Cess section °F the desiccant wheel as a cooling source to reduce the effects °F adsorption heat and carryover heat. A model validated by the experimental data for internally cooled desiccant wheel and a commercial indirect evaporative cooler are then adopted to assess the performance °F the DWAC system. Results show that for inlet air conditions °F 95°F (35°C) and 60% relative humidity, the proposed DWAC system with internally cooled desiccant wheel could adsorb at least 0.0053lb (2.4g) moisture more (for per 2.2lb (1kg) dry air dry air) per second compared to a DWAC system using an adiabatic wheel when regeneration air temperature is 140°F (60°C) which could be easily gotten from a solar thermal collector. In addition, the electrical coefficient °F performance for the internally cooled desiccant wheel system is calculated to be between 7 and 13 compared to 5.2 to 8.2 for the adiabatic wheel system. These results indicate that a DWAC system with an internally cooled wheel would be up to twice as efficient as the most efficient split system air-conditioners and three times as efficient as the Australian market average °F new installed split systems in 2014 in hot and humid climate (dry bulb temperature is 95°F (35°C) and relative humidity is 60%).
