Assessment, Sizing, and Economic Evaluation of a CCHP Plan for an Office Facility

Abstract

Abstract Due to its potential for greater thermal efficiency compared to standalone power production systems, Combined Cooling, Heating and Power (CCHP) systems have drawn significant attention over the past few decades. The primary goal of this investigation is to provide insights on implementing a CCHP system in an Iranian office building. Choosing the right amount of equipment capacity is one of the most important factors in achieving this goal. Regarding to this, various scenarios and alternatives are introduced based on the gas turbine capacity. The optimal alternative is determined based on a technical and economic analysis, regarding the availability of each alternative. In the end, a study is conducted and pertinent data are provided on decreasing pollutant emissions owing to the implementation of a CCHP system in this office building. In light of Iran's present energy situation, it's important to design the prime mover's optimal capacity so that its electricity generating capacities (based on peak load) are in line with the building's electric demand. In addition, this office building's natural gas and residential electricity usage have an estimated annual impact on the surrounding neighborhood of $80,000.
