Résumé

A first part was dedicated to energy audits concerning steam boilers. The second part of the paper discusses a novel methodology for determination of the efficiencies of each segment in a centralized air-conditioning plant. The methodology is useful analytical tool in energy audit where it can be used for decision support for evolution of energy conservation measures and techno-economic evaluation of the various options. The procedure is applied to three air-conditioning plants of capacity range from 50 to 500 TR. Losses in chilled air ducts and cycling losses in the refrigerant circuit are identified to be the most important parameters. Effective controls and insulation of air ducts have been shown to be the most cost effective solutions.
