Study about the possibility of use micro-CHP systems at home

Abstract

This work is made with the goal of analyse the possibility of introduce the micro-CHP (Combined Heat and Power) systems for the distribution on electric and thermal energy in a building of 25 apartments. The work studies 3 different systems of cogeneration: Internal Combustion Engine (ICE), Micro Gas Turbine (MGT), Stirling All of these systems are available in the market. Each system of generation is composed of one Prime Move (PM), a thermal energy storage unit and an auxiliary boiler used to cover peak thermal demands. For made this study we are based in cover the demand of a building of 25 apartments, all of the with the same surface and the same characteristics. At the end of this paper we could decide which of these technologies is the most developed, as well as the technology that needs more time to be developed. Usually, the introduction of these systems of cogeneration make reduce the energy taken of the grid more of 20%, and improving the feasibility of the engine.
