It is well established that the thermal efficiency of a heat engine increases as the temperature TL at which heat is rejected from the heat engine decreases. In an effort to increase the efficiency of a power plant, somebody suggests refrigerating the cooling water before it enters the condenser, where heat rejection takes place. Would you be in favor of this idea? Why?

Question

It is well established that the thermal efficiency of a
heat engine increases as the temperature TL at which heat is
rejected from the heat engine decreases. In an effort to increase
the efficiency of a power plant, somebody suggests refrigerating
the cooling water before it enters the condenser, where heat
rejection takes place. Would you be in favor of this idea? Why?
