Abstract:

The air-conditioning systems utilizing liquiddehumidification are playing a positive role in energysavingHowever，the expectation of wider application is frustrated due to the poor dehumidification effect compared to the soliddehumidification systemTo enhance the liquid dehumidification ability，this presents paper the research from two sides：improvement of the dehumidifier by introducing solid adsorbent on its surface; and the use of mixed solution as liquid desiccantThe electrolyte theory was used to investigate the thermal properties of the liquid desiccant in order to select an ideal liquid desiccant and its mixing ratioThe related experiments were carried out，and the results showed that the improved dehumidifier contributed to the capability enhancement not only thanks to the area enlargement but also the possible superposition of adsorption potentialsOn the other hand，the mixed solution greatly improved the dehumidification effect compared to the case of using a single liquid desiccant.
