A novel concept for a rack-integrated adsorption chiller integrates a compact adsorption chiller within each server rack for hybrid liquid/air cooling. This system utilizes the server's waste heat as the driving input for the ad/desorption processes. The compact design incorporates direct evaporation/condensation heat exchangers, enabling refrigerant distribution entirely in the liquid phase. This work presents a preliminary lumped-parameter model of the rack-integrated adsorption chiller, focusing on its conceptual framework and preliminary results. The model consists of a system of 10 ordinary differential equations, addressing the energy and mass balances of various components.

Abstract
A novel concept for a rack-integrated adsorption chiller integrates a compact adsorption chiller within each server rack for hybrid liquid/air cooling. This system utilizes the server's waste heat as the driving input for the ad/desorption processes. The compact design incorporates direct evaporation/condensation heat exchangers, enabling refrigerant distribution entirely in the liquid phase. This work presents a preliminary lumped-parameter model of the rack-integrated adsorption chiller, focusing on its conceptual framework and preliminary results. The model consists of a system of 10 ordinary differential equations, addressing the energy and mass balances of various components.| File | Dimensione | Formato | |
