Energy performance of a residential building-integrated micro-cogeneration system upon varying thermal load and control logic

This work investigated the energy performance of a 6.0 kWel micro-cogeneration device integrated with a multi-family house by using a dynamic simulation software. The analyses were performed upon varying the climatic conditions, the control logic of the cogeneration unit, the number of flats composing the building and the target temperature of hot water produced for heating purposes. The simulation data were used to compare the performance of the proposed system with those of a conventional system composed of a natural gas-fired boiler and a power plant mix connected to the electric grid from an energy point of view.
