Scope

In the future, micro CHP plants are assumed to supply power and heat for single-family and multi-family houses. Planners and installers of the plants need to consider specific requirements regarding the design and dimensioning. Particularly the design of the electrical and thermal performance of the micro CHP device and the supplementary heater as well as the size of the heat storage unit and further required components have to be taken into account. The standard describes methods based on standard VDI 4655 for the use of the reference load profiles in standard application case. This allows to compare different micro CHP technologies and different dimension
