Simplified strategy for modeling the performance of a novel multi house heating schemes
Authors: John Rogers
Abstract
Low carbon heating schemes frequently consist of a number of heat sources with different emission factors, a thermal store and heat distribution network. These need detailed models with short update periods to accurately predict their performance. However if you wish to establish the running patterns associated with the different heat source it can be assumed that tradition heat distribution networks work. This simplifies the modelling as the run period is dependent on thermal inertia of the heat store. This approach has been used to model the performance of a micro district heating scheme supplying three houses in the UK from a combination of a micro CHP unit, condensing gas boiler and solar water heaters. The model allowed each house to have variable heat loads and it was found that this combination of technologies produced a considerable reduction in annual CO2 emissions.
