Preliminary Design and Piping Diagram for a Combined Heat and Power System $ For the College of Engineering at the University of Louisiana Lafayette Using Donated Equipment

摘要

Combined heat and power (CHP) systems have many different factors in design procedures. The configuration of a CHP system can be changed to affect different factors of the design and to meet specific needs of the system. Before the design process can begin, product specifications, such as steam or water pressures and temperatures, and equipment, such as absorption chillers and heat exchangers, need to be identified and defined. The objective of this paper is to lay out a preliminary design of the CHP system at the College of Engineering at the University of Louisiana, Lafayette. First, a flow chart is presented depicting a broad scope model of the whole system. Then, the specifications of the absorption chiller and the heat exchanger to be used in the system are calculated by working out the flow rates of the water circuits and the temperature of the exhaust gas. Once these are determined, a piping and instrumentation diagram is shown, based on these calculations. Most of the equipment was donated to the University for work in the Energy Engineering Laboratory of the Mechanical Engineering Department and the Industrial Assessment Center. Our design work involves connecting all of the donated and other equipment to make our CHP system.
