3. Machines consuming mechanical energy

Figure 2 shows such a system, which is at least ditheric. Thanks to the mechanical (or equivalent) energy W supplied to this system, thermal energy QF is absorbed at the cold source, at thermodynamic temperature T F , and thermal energy QC is rejected at the hot sink, at temperature T C . Instead of looking at energies, we can look at the powers involved. As a result of the mechanical power supplied W˙ , cooling power
