to increase the efficiency of the CHP units
The heat and total efficiency of the CHP unit will increase as a result of the combination of the CHP unit with a heat pump. This increase is approximately 3% depending on the specific installation. The heat pump makes use of low-potential heat from the aftercooler circuit, which will be fully utilized due to the temperature increase. This solution will provide double profit: Elimination of the requirement to install an external aftercooler and further utilization of additional heat. Retrofitting a CHP unit with a heat pump is a convenient solution for all the applications where the highest heat efficiency matters, typically, in district heating systems.
