Effects of a CHP System with Cooling on Carbon Dioxide Emissions In Full and Partial Cooling Load Applications

摘要

Combined heat and power technology is one of the few market-proven power generation solutions for reducing energy usage and greenhouse gas emissions. This work assesses the net emissions reduction from installing a CHP system with absorption cooling (a CCHP system) as an alternative to a state of the art variable speed centrifugal chiller. A full load analysis is presented that examines the performance of the CCHP system installed as an alternative to a fully loaded centrifugal chiller. A part load analysis is presented that examines the performance of the same CCHP system installed as an alternative to the same chiller operating at part load. A sensitivity analysis was performed to compare the relative impact of cooling hours versus the local emissions coefficients to determine the factor that has the strongest effect on emissions reduction projects. The calculations and results of the analyses are presented and recommendations made as to the most effective designs and locations for installation of CCHP systems for reducing emissions.
