ASHRAE 90555-2015 COMBINED HEAT AND POWER DESIGN GUIDE.pdf

1、RP-1592 COMBINED HEAT AND POWER DESIGN GUIDEComplete Guide to Combined Heat and Power Combined Heat and Power Design Guide was written by industry experts to give system designers a current, authoritative guide on implementing combined heat and power (CHP) systems. CHP systems provide electricity an

2、d useful thermal energy in a single, integrated system. Heat that is normally wasted in conventional power generation is recovered as useful energy, avoiding the losses that would otherwise be incurred from separate generation of heat and power. Recent advances in electricity- ef cient, cost-effecti

3、ve generation technologiesin particular, advanced combustion turbines and reciprocating engineshave allowed for new con gurations of systems that combine heat and power production, expanding opportunities for these systems and increasing the amount of electricity they can produce. Combined Heat and

4、Power Design Guide provides a consistent and reliable approach to assessing any sites potential to economically use CHP systems. This guide provides up-to-date application and operational information about prime movers, heat recovery devices, and thermally activated technologies; technical and econo

5、mic guidance regarding CHP systems design, site screening, and assessment guidance and tools; and installation, operation, and maintenance advice. As well as a glossary of terms, the book features extensive, detailed case studies on implementations in university, industrial, and hotel settings. Info

6、rmation is presented in both Inch-Pound (I-P) and International System (SI) units. Also included with the book is access to the newly developed ASHRAE CHP Analysis Tool, a Microsoft Excel spreadsheet (in I-P units only) for use in assessing sites for CHP applicability. Combined Heat and Power Design

7、 Guide is an essential resource for consulting engineers, architects, building owners, and contractors who are involved in evaluating, selecting, designing, installing, operating, and maintaining these systems. 9 781936 50487 9 1791 Tullie Circle Atlanta, GA 30329-2305 404-636-8400 (worldwide) www.a
