The present study aimed at fulfilling the necessity of thermal comfort air in a defined space. A novel -humidifier system where the grey/saline water is filtered and used in an evaporative cooling system to fulfil the requirements of thermal comfort air. Water is made to pass through the first stage of packing to filter the contaminated water, and it is filtered again in a humidifier packing section, which then mixes with air to undergo humidification with reduction in its temperature. Experiments were conducted to evaluate, air quality, and system performance. Various humidification parameters such as humidification efficiency, coefficient of performance (COP), change in pressure and specific humidity were determined. Experimental results indicated that, with the rise in the liquid-to-gas ratio, there is a rise in a change in temperature, specific humidity and COP. The system yielded maximum efficiency, pressure drop, COP, specific humidity change, and a temperature drop of 84 %, 270 Pa, 1.85, 1 g/kg and 5.3 °C respectively. Air quality measurement revealed that departing air offered good thermal comfort without any pollution. Therefore, the innovative system proves beneficial in hot areas that experience significant cooling demands, such as countries in the Middle East, which also face a scarcity of fresh water.

基于可持续技术的新型加湿器系统的评估

本研究旨在满足特定空间内热舒适空气的必要性。一种新颖的加湿器系统，其中灰水/盐水经过过滤并用于蒸发冷却系统，以满足热舒适空气的要求。水通过第一级填料过滤污染水，并在加湿器填料段再次过滤，然后与空气混合进行加湿和降温。进行实验来评估空气质量和系统性能。确定了各种加湿参数，如加湿效率、性能系数 (COP)、压力变化和比湿度。实验结果表明，随着液气比的增大，温度、比湿度和COP的变化也增大。该系统实现了最大效率、压降、COP、比湿度变化和温降，分别为 84%、270 Pa、1.85、1 g/kg 和 5.3 °C。空气质量测量表明，排出的空气具有良好的热舒适性，且没有任何污染。因此，事实证明，该创新系统在需要大量冷却的炎热地区（例如也面临淡水短缺的中东国家）是有益的。
