For the buildings with higher moisture loads such as natatoriums, it is essential to regulate the air temperature and humidity accurately during the year-round. However, the conventional dehumidification air conditioning system is still commonly utilized, which requires considerable energy consumption. In this paper, the heat pump-driven liquid desiccant dehumidification system integrated with fresh air supply is developed. Nevertheless, considering the multi climate conditions through the year, the operating modes adapted to various conditions are seldom specified, let alone the energy-saving effects compared to traditional dehumidification systems. According to the temperature and moisture diagram, the partitions and corresponding operating modes are firstly presented. Then, the energy consumptions are compared extensively to identify the applicability of each operating mode. The modified temperature-moisture partitions are ultimately presented. Results show that with the introduced auxiliary condenser, the energy efficiency is improved by 7.5% to 63.4% in the summer conditions. Compared with the traditional dehumidification system, the maximum energy-saving rate could reach up to 92%. The optimized system could regulate the relevant components to meet the temperature and humidity requirements of high-humidity buildings throughout the year.

热泵驱动液体除湿系统在不同气候条件下的性能研究和节能潜力


对于游泳馆等水分负荷较高的建筑物，全年准确调节空气温度和湿度至关重要。但是，传统的除湿空调系统仍然普遍使用，这需要相当大的能源消耗。本文开发了热泵驱动液体干燥剂除湿与新风供应一体化的系统。然而，考虑到全年的多种气候条件，适应各种条件的运行模式很少指定，更不用说与传统除湿系统相比的节能效果了。根据温度和湿度图，首先给出了分区和相应的运行模式。然后，对能耗进行广泛比较，以确定每种操作模式的适用性。最终给出了修改后的温度-湿度分区。结果表明，引入辅助冷凝器后，夏季条件下的能源效率提高了 7.5% 至 63.4%。与传统的除湿系统相比，最高节能率可达 92%。优化的系统可以调节相关组件，以满足高湿度建筑物全年的温度和湿度要求。
