Résumé

Liquid desiccant cooling is a great alternative to vapour compression cooling for air-conditioning system in buildings with immense energy saving potential. After dehumidification of fresh air, the dehumidified water can be used further for evaporative cooling. However, the recovery of water from regenerator exhaust is a slow process and impractical to be utilised as feed water for evaporative cooling. To overcome this problem, low temperature regeneration of diluted desiccant solution with evaporative mist cooling can be achieved by ultrasonic technology. In this work, a novel regenerative evaporative cooler through the Maisotsenko Cycle (M-Cycle) integrated with an ultrasonic atomizer for liquid desiccant regeneration was fabricated. Moisture removal and effectiveness of the system were studied under various air and desiccant temperature, air and desiccant flow rate, humidity ratio and desiccant concentration. Low temperature (35–50 °C) regeneration of diluted desiccant was accomplished by 0.208–0.619 g s−1 of moisture removal rate. Room cooling supply air temperature below the wet-bulb temperature of intake air up to a minimum temperature of 19 °C was effortlessly achieved by evaporative cooling of atomized water mist from the regenerator.
