基于溶液除湿潜能的蓄能模式,构建一种新型除湿潜能释能冷水机组,以给空调系统提供冷源,特别是为辐射供冷的空调系统提供冷源途径。介绍了新构建系统的流程形式与工作过程,阐述了潜能蓄能机理,从理论上计算分析了该系统的单位理想制冷量随蒸发温度、冷却水温度和溶液浓度的变化关系,数据结果表明该系统在一定工况下能获取空调用冷水,并具有较大的单位理想制冷量,单位理想制冷量能达到10kW,该系统所能获取冷冻水的理论最低温度为除湿干燥后湿空气的露点温度。

A new type of chiller system relying on desiccant potential discharging was constructed based on the energy storage mode using liquor desiccant potential, which was able to provide cooling resource for air conditioning system and especially for radiant cooling air conditioning. The mechanism about the energy storage mode - using desiccant potential was explained. The influence of evaporative temperature, cooling water temperature, and liquor concentration on the normalized cooling capacity of the system was calculated and analyzed theoretically. The results show that the system could obtain chiller water for air conditioning under designated operation conditions and the high - normalized cooling capacity could reach 10 kW. In addition, the minimum temperature of the chiller water provided by the system depended on dew point temperature of the air after dehumidification.
