Description
技术领域technical field
本实用新型属于空气取水技术领域，特别是一种利用太阳能的节能空气取水系统，能效比高。The utility model belongs to the technical field of air water intake, in particular to an energy-saving air water intake system using solar energy, which has high energy efficiency ratio.
背景技术Background technique
从空气中取水是解决水资源不足的重要途径。空气取水主要针对室外自然空气，并将空气中的水蒸气尽可能地转化为更多的液态水。然而，由于空气取水的难度与空气含湿量极为相关，从含湿量小的空气中制取淡水难度很大。Taking water from the air is an important way to solve the shortage of water resources. The air water intake is mainly aimed at the outdoor natural air, and converts the water vapor in the air into more liquid water as much as possible. However, since the difficulty of obtaining water from the air is closely related to the moisture content of the air, it is very difficult to produce fresh water from air with low moisture content.
为从干燥空气中提取水分，中国发明专利申请“从干燥空气中取水的方法及装置”(申请人：中国人民解放军理工大学，申请号：201410799635.2,申请日：2014.12.19)涉及一种从干燥空气中取水的装置，包括除湿转轮和表面冷却器，除湿转轮的再生空气出口与表面冷却器的进风口相通，表面冷却器为蒸气压缩制冷系统的蒸发器(如图1所示)。该装置充分利用除湿转轮在低湿度下的吸附取水能力和蒸气压缩制冷系统的蒸发器在高湿度下的强析湿能力，实现连续、高效、节能地从干燥空气中取水的目的，同时充分利用蒸气压缩制冷系统的冷凝器的余热作为除湿转轮的再生热量，可以进一步提高整个取水方法的效率。In order to extract water from dry air, the Chinese invention patent application "Method and device for taking water from dry air" (applicant: Chinese People's Liberation Army University of Science and Technology, application number: 201410799635.2, application date: 2014.12.19) involves a The device for taking water from the air includes a dehumidification rotor and a surface cooler. The regeneration air outlet of the dehumidification rotor communicates with the air inlet of the surface cooler. The surface cooler is the evaporator of the vapor compression refrigeration system (as shown in Figure 1). The device makes full use of the adsorption capacity of the desiccant wheel at low humidity and the strong dehumidification capacity of the evaporator of the vapor compression refrigeration system at high humidity to achieve the purpose of continuously, efficiently and energy-savingly taking water from dry air. Using the waste heat of the condenser of the vapor compression refrigeration system as the regeneration heat of the dehumidification wheel can further improve the efficiency of the whole water extraction method.
然而，由于除湿转轮的解吸效果与进入其再生区的空气正相关，即进风温度越高，解吸效果越好；为充分将富集的水分解吸出来，需要消耗大量的能量提高除湿转轮再生区的进风温度。However, since the desorption effect of the desiccant rotor is positively correlated with the air entering its regeneration zone, that is, the higher the inlet air temperature, the better the desorption effect; in order to fully desorb the enriched water, it is necessary to consume a lot of energy to improve the desiccant rotor. Inlet air temperature in regeneration zone.
因此，现有从干燥空气中取水的装置存在的问题是：能耗大，能效比低。Therefore, the existing devices for taking water from dry air have the following problems: high energy consumption and low energy efficiency ratio.
