Title: Combined Heating and Power Using Microturbines in a Major Urban Hotel

Abstract

This paper describes the results of a cooperative effort to install and operate a Cooling, Heating and Power (CHP) System at a major hotel in San Francisco, CA. The packaged CHP System integrated four microturbines, a double-effect absorption chiller, two fuel gas boosters, and the control hardware and software to ensure that the system operated predictably, reliably, and safely. The chiller was directly energized by the recycled hot exhaust from the microturbines, and could be configured to provide either chilled or hot water. As installed, the system was capable of providing up to 227 kW of net electrical power and 142 Refrigeration Tons (RT) of chilled water at a 59oF (15oC) ambient temperature. For the year, the CHP efficiency was 54 percent. Significant lessons learned from this test and verification project are discussed as well as measured performance and economic considerations.
