Techno-Economic Analysis of Waste Heat Utilization in Data Centers: Application of Absorption Chiller Systems

Modern data centers are playing a pivotal role in the global economic situation. Unlike high-quality source of waste heat, it is challenging to recover decentralized and low-quality heat sourced from due numerous technological hurdles. As such, utmost importance explore possible pathways maximize energy efficiency utilize their recovery. Absorption chiller systems promising technology for recovery at ultra-low temperatures. In fact, low temperature discharged cannot be retrieved with conventional systems. Therefore, present study investigated feasibility using an absorption system, ultimate goal electrical production. To fulfill this objective, techno-economic assessment (AC) technique power consumption range 4.5 13.5 MW performed. The proposed AC system enables saving electricity value 4,340,000 kWh/year 13,025,000 leading annual reduction 3068 9208 tons CO2 equivalent greenhouse gas (GHG) emissions, respectively. results suggest optimum change design center while reducing payback period investors.
