In an energy hub, each energy carrier can be converted to other forms of energy to meet electricity, heating and cooling power demand in an optimal manner. In this study, a framework is presented to optimally design and size interconnected energy hubs. It considers physical constraints on natural gas and electricity networks and environmental issues. The proposed design methodology decides on w...

GAS-FUELED ENGINE-DRIVEN AIR CONDITIONING AND REFRIGERATION SYSTEMS FOR COMMERCIAL BUILDINGS Bruce B. Lindsay Project Manager commercial Space conditioning Gas Research Institute 8600 W. Bryn Mawr Avenue Chicago, IL 60631 Since 1985, the author has been involved in a program to develop a nominal 150 ton gas-fueled engine-driven water chiller for commercial buildings. The packaged system has bee...

A steady-state model for a centralized cooling system is developed to enable proper provisioning of cooling resources in capital intensive projects such as data centers. The model resolves the energy equations for a cooling tower and a centralized water-cooled chiller simultaneously. It requires inputs that are readily available to the design engineer. The user inputs are the ambient conditions...

A methodology for assessing solar cooling technologies is proposed. The method takes into account location specific boundary conditions such as the cooling demand time series, solar resource availability, climatic conditions, component cost and component performance characteristics. This methodology evaluates the techno-economic performance of the solar collector/chiller system. We demonstrate ...

In the present study, exhaust gases from Tehran refinery crude oil furnace are used in a Heat Recovery Steam Generator (HRSG)for generating steam. Then, the steam is directed to a double effect absorption refrigeration cycle to produce cooling. To meet the object, mass and energy balance equations of the coupling is carried out for both the HRSG and the absorption chiller and unknown thermodyna...

Solar ponds are characterized by high storage capacity and the ability to provide a stable continuous power source. Careful selection of extraction rate helps maintain supply temperature in range suitable for operation an absorption unit. This study proposed system which solar pond is coupled with chiller investigate resulting advantages. The cooled using water upper convective zone, ensures th...
