Comparative study of heat production by cogeneration or heat pump

Abstract : Considering Carnot cycles, it is shown that reducing the power of a thermal power plant to produce cogeneration or using this difference in power to run heat pumps is equivalent in terms of overall performance. Practically, this is however not the same. This conclusion is put in evidence when considering an actual 280 MW power cycle and Rl34a, R600 and R717 heat pumps. It is shown that depending on the operating temperatures of the heat pumps and the heating network transmission losses, the overall cogeneration performance can be higher than the use of heat pumps in many configurations.
