Résumé

We apprehend heat transfer from the body at higher temperature to the body at lower temperature at heat exchange as a fundamental property of environment. But as it is known the direction of a thermodynamical process passing is determined by entropy, and in the case of non­equilibrium heat exchange it may lead to heat transfer in unusual direction. In the thermodynamical system in which a non­monotonous dependence exists between entropy and energy, for example, when a molecular construction of one of the bodies has a limited number of a quantum state, a spontaneous heat transfer from the body at lower temperature to the body at higher temperature is possible.
