Optimal Heat Transfer during the Change of Phase State of a Refrigerating Medium

Abstract

The problem of the minimal gain of the entropy of a system of heat transfer with a defined heat load and heat transfer surface during the change of the phase state of one of the contacting refrigerants is considered. The laws on the change of temperatures of hot and cold flows corresponding to the optimal solution are found. The possibilities of implementing the optimal heat transfer in a stationary system are considered.
