除湿蒸发冷却空调系统的优化设计

设计一种可利用低品位热能的溶液除湿蒸发冷却空调系统。对此空调系统进行理论分析，得出如下结论：在溶液除湿蒸发冷却空调系统的多种实现形式中，新风经除湿后与回风混合比新回风混合后再除湿节能；将室内排风返回溶液再生器，进行热湿交换，既可加疆对处理空气的预冷，回收排风冷量，又可提高再生器的效率，降低系统能耗；把回热器吸收除湿浓溶液中的部分热量用于溶液再生器的稀溶液预热，可以提高溶液的再生性能。为除湿蒸发冷却空调系统的优化设计提供理论依据。

Optimization design of desiccant evaporative cooling air-conditioning

Designs a liquid desiccant cooling air-conditioning system using low tempera- ture heat. According to the theoretical analysis, the results show that the fresh air dehumidified before mixed with return air is more energy-saving among many kinds of realization shapes. Indoor exhaust used as regeneration air can also reduce the total energy consumption of the system. It may enhance the regeneration property when the recuperator is adopted to absorb energy to preheat the dilute liquid. The design and analysis of this system provides a theoretical basis for the optimization design of liquid desiccant cooling airconditioning system.
