With the increasing requirements of people on the temperature, the humidity, the energy conservation and the environmental protection of indoor environment, for example, in the places of military affairs, pharmacy, electronics, food, light industry and the like, some places with low-humidity environment requirements are proposed. Currently, the dehumidification and air conditioning products widely adopt a vapor compression refrigeration principle, the optimal use temperature is generally 18-40 ℃, and the moisture content of the treated dry air is more than 6.5 g/kg. When the moisture content is lower, such as 18 ℃, the moisture content is 4.0g/kg, the corresponding air relative humidity is 31.02%, and the dew point temperature is 0.90 ℃, and then the surface fin temperature of the evaporator can be dehumidified only when being lower than the dew point temperature, so that the traditional cooling dehumidification is difficult to process and even cannot be solved. With the development of dehumidification technology, some new dehumidification methods, such as membrane method dehumidification, solution dehumidification, solid dehumidification and the like, appear in succession, and bring some ways for the industry to meet the low-humidity requirement.

But the defects are also obvious: the currently commonly used solutions with good hygroscopicity, such as lithium chloride (LiCl), lithium bromide (LiBr) and calcium chloride (CaCl)2) The solution and the like all have certain corrosive action, an independent and corrosion-resistant regenerator and a dehumidifier have to be adopted, and non-metallic packing is arranged in the solution for spray exchange, but the solution cannot be directly sprayed on an evaporator or a condenser, so that the volume and the cost of the equipment are reducedThe increase of the cost simultaneously has the risks of air pollution, solution pollution caused by outdoor wind sand and the like; secondly, when the equipment is required to be placed indoors or in a vehicle, an external air port is required to ensure that moist hot air blown out by the regenerator is discharged outdoors, and meanwhile, corresponding air inlet compensation is also required to be solved, including treatment on inlet air temperature and humidity and the like, and like a rotary dehumidifier, regenerated hot air generated by electric heating is required to be continuously discharged outdoors. These deficiencies restrict further development of solution dehumidification. Good news is that with the development of new dehumidification solution technology, some solutions which are non-corrosive, sterilization and poison inhibition, safe and harmless appear, such as novel ionic moisture absorption liquid, which brings possibility to the innovative design of new products.
