Description

technical field [0001] The invention relates to the technical field of dehumidification and air conditioning equipment, in particular to a compression boiling regenerative solar energy dehumidification system. Background technique [0002] Air humidity not only affects people's thermal comfort, but also has an important impact on industrial production activities. Therefore, humidity control is one of the important tasks of air conditioning engineering. The local area of ​​the underground project including the underground powerhouse of the hydropower station has high humidity. In addition to the easy precipitation of condensed water on the surface of the enclosure structure, which gradually causes water accumulation on the ground, it also seriously affects the normal operation and service life of the electrical equipment in this area. The traditional cooling dehumidifier used in the underground powerhouse of the hydropower station is difficult to discharge the condensed water...

AI Technical Summary

Problems solved by technology

Packed spray tower is a traditional common non-boiling evaporative solution regeneration device. This regeneration method requires a lower heat source temperature and can use low-grade energy, but there are also problems with low regeneration efficiency and low concentration of the regenerated solution that lead to dehumidification. Disadvantages such as large spray tower

In addition, the non-boiling regeneration of the packed spray tower is also affected by the outdoor air humidity. When the outdoor air humidity is high, it is not conducive to solution regeneration

The solution boiling evaporation regeneration equipment can regenerate a higher concentration solution, and the regeneration efficiency is also higher, but the required heat source temperature is higher, and it is often driven by high-quality energy such as natural gas, which consumes more energy

[0004] The Chinese invention patent with the publication number CN1415909A proposes a multi-stage liquid dehumidification method. Although the dehumidification efficiency is improved, it is still a non-boiling regeneration method, which has the inherent shortcomings of the non-boiling regeneration method, that is, the regeneration efficiency is low, and Complex dehumidification system equipment structure

[0005] The Chinese invention patent with the publication number CN102853485A proposes a boiling regenerative solution dehumidification system driven by solar energy and ground source energy, which can effectively utilize two renewable energy sources, solar energy and geothermal energy, and expand the scope of energy utilization and the application of the system range, using the boiling regeneration method, the concentration of the solution produced is also high, but it has the disadvantages of complex system structure, expensive drilling of buried pipes, which leads to increased system costs, etc. Influenced by thermal properties, its application range is also limited
