Residential CHP System Analysis

Combined Heat and Power (CHP) systems are a focus of building energy system designers. These systems combine building heating and electrical power systems, (also known as Cogeneration systems) with cooling to provide a total energy package for a home.

This project focused on an analytical assessment of CHP performance in various geographical regions of the US. Weather data from BinMaker® software was used to create a database of hourly weather observations for 14 US cities. Utility cost information was gathered for these locations as well.

A system model was created in Visual Basic that contained operating characteristics for the natural gas engine, electrical generator, interface heat exchangers and the heat pump. These characteristics were temperature dependent such that the model was sensitive to the daily and annual weather variations.
