Integration of Air to Water Heat Pump into District Heating System with Combined Heat Power Plant

摘要

the scope of the work is solving the multicriteria task - determination of the optimal ratio between the heat rejected from the return water and the external air for designing of heat pump of maximum efficiency. The goal has been achieved by resolving the following tasks: energy efficency calculus of Combined Heat Power Plant (CHPP) with district heating pumps using a part of return water heat and using ambient air as source of low temperature heat for hot water production, elaboration thermodynamical cycles for heat pump.
