Performance estimation of a rotary dehumidifier with the influence of design and operation parameter.

Summary

A desiccant rotor and its applied system have a lot of potential to utilize waste thermal energy for refrigeration and air-conditioning demand. A recent cogeneration system supplies waste heat which temperature is around 60°C. It needs to develop a high efficiency rotor regenerated by such a low-grade thermal energy. The aim of the study is to evaluate the dehumidification performance of rotor having some different equilibrium adsorption characteristics using a dynamic rotor simulation. It was clarified that the dehumidification rate changes steeply with the regeneration temperature, and there was an optimized regeneration temperature reaching the maximum of the dehumidification efficiency. It was also examined that the optimum adsorption zone angle and rotor length was depended on the regeneration temperature. The influence of a hysteresis curve of adsorption characteristics and equivalent mass transfer coefficient on the rotor performance is not negligible.
