【Abstract】 This paper presents a novel experimental and analytical waste heat recovery and dehumidification system on the recovery of waste heat from data centers. The proposed system uses desiccant-coated heat exchangers to harvest waste heat and utilize it for the dehumidification of fresh air, thus enabling local consumption of the recovered waste heat. The study focuses on a liquid-cooled data center at a research institute in Shanghai as the experimental subject. The performance of the waste heat recovery and dehumidification system was evaluated through a series of tests. Results show that the system is capable of recovering waste heat at 50℃ from the liquidcooled data center to continuously dehumidify fresh air. The average coefficient of performance(COP) for dehumidification reaches 8.85. Furthermore, at an airflow rate of 4500 m~3/h and a dehumidification duration time of 6 minutes, the average waste heat recovery efficiency achieves 41.94%.更多还原
