Optimal heating: maintaining a non-equilibrium temperature field in a multi-chamber system with minimum energy consumption

The heating system is considered as a multi-flow heat exchange system. It is shown that the criterion of its thermodynamic perfection can be minimally attainable irreversibility (dissipation). General conditions of minimal dissipation of heat exchange systems are used to obtain recommendations for the design of heating systems. The distributions of the total heat transfer coefficient and the coolant temperature in contact with the air in the heated rooms are obtained. (In Russian).
