A heat pump has a coefficient of performance of 2 using a power input of 2 kW. Its low temperature is To and the high temperature is 80°C, with an ambient at To. Find the fluxes of exergy associated with the energy fluxes in and out.
First let us do the energies in and out
Remark: The process then destroys (2 – 0.623) kW of exergy.
