CHP

An economic and environmental analysis on residential internal combustion engine (ICE) based cogeneration in Canada was performed. Information from three publicly available databases was used to model four houses to be used in simulation. One house per Canadian region was chosen and modeled in ESP-r. Annual simulations using the existing space and domestic hot water heating equipment were performed and these base case results were compared to the results using the ICE based cogeneration system.

District Heating and Cooling system (DHC) is an efficient energy system as they can supply chilled andheating water/steam effectively by integrating heating and cooling demand of neighboring buildings.However, there is possibility for further improvement of energy efficiency by integrated operation ofadjacent DHC and utilizing waste heat from municipal incinerators and CHPs. In this study, the effect ofsuch flexible use of heat and electricity in integrated DHC systems is examined. The main object is toraise total thermal efficiency and reduce CO2 emission.

We investigate optimal supervisory control of a building energy system with cogeneration of heat and power (CHP). The system consists of a Stirling engine and a supplementary burner, space heating and a domestic hot water (DHW) storage tank. Cost and primary energy (PE)-optimal operation are considered.
The best theoretically possible operating strategy is found using the following assumptions:
