Waste heat recovery and utilization technology based indirect evaporative cooling system in data centers

Aiming at the current situation that there is no implementable waste heat recovery and utilization technology for the indirect evaporative cooling air conditioning systems in the data center industry, this paper analyses the difficult problems existing in the application of waste heat recovery technology in indirect evaporative cooling air conditioning systems and presents two solutions. By respectively adopting the magnetic levitation phase change cooling technology and water-source heat pump technology, the waste heat in the hot return air is fully recovered. Meanwhile, taking advantage of the characteristics of the building structure, an independent waste heat recovery site is set up to physically isolate the waste heat recovery from the indirect evaporative cooling system without mutual interference. While solving numerous problems in waste heat recovery of traditional indirect evaporative cooling systems, it also improves the redundancy safety and stability of the system refrigeration.
