Description

technical field [0001] The invention relates to the technical field of solution humidity control, in particular to a solution humidity control fresh air unit based on a water ring heat pump heat source. Background technique [0002] With the progress and development of society, people have higher requirements for indoor air quality and the comfort of hot and humid environments. However, traditional refrigeration dehumidification has problems such as offsetting cold and heat, and can only dehumidify but not humidify. Many researchers have gradually turned to solution conditioning. Research on humidity technology, this technology uses salt solution with the function of humidity control (dehumidification and humidification collectively referred to as humidity control) as the medium, such as lithium bromide, lithium chloride or calcium chloride and other salt solutions to adjust the humidity of the air, which can be used The low-grade heat source can remove dust, bacteria and mo...

AI Technical Summary

Problems solved by technology

[0004] 1. In order to achieve solution regeneration, the compressor needs to be turned on all the time, which consumes a lot of energy;

[0005] 2. Due to the continuous operation of the system, there is an imbalance between the heat required for solution regeneration and the cooling capacity required for solution dehumidification, and the excess condensation heat cannot be eliminated;

[0006] Both the solution regeneration and the solution humidity control cycle exchange heat with the components of the compression refrigerator, the system layout is limited by the compression refrigeration cycle pipeline, the equipment pipeline is complex, the maintenance space is narrow, and maintenance is difficult
