Energy Enhancement in a Packed-Bed Cross- Flow Humidifier

Byspraying water in air known as humidification process, the moisture content in air isincreased, which has a significant impact on air conditioning and desalination processes. In a packed-bed humidifier, the major challenges are the improvement in water vapor content in exit air and pressure drop across the material used for packaging within the humidifier. From the literature survey, cellulose packing, made of corrugated cellulose papers, appears to be the best. The focus of this paper is to fill the research void regarding how the positioning of packing materials affects the performance of humidifiers. The study involves conducting experiments where air and water flow rates are systematically adjusted, and various performance parameters, including humidity efficiency, Coefficient of Performance (COP), and Specific Cooling Capacity (SCC), are quantified. The system demonstrated a peak Coefficient of Performance (COP) of 4.29, a Specific Cooling Capacity of 2.3kWh/kg, and a Humidification Effectiveness of 81.86%. In summary, the performance of three Cellulose packing pads surpasses that of two Cellulose packing pads, showcasing superior performance in terms of Higher Relative Humidity (RH), COP, Specific Cooling Capacity, and Humidification Effectiveness.
