In recent decades, changes in temperature and humidity have been used in many fields of technology: chemical technology, metallurgy, oil refining, mechanical engineering, biology and space research. One of the important issues in space exploration is the creation of closed facilities for the study of underwater processes. For large-scale systems, it is necessary to maintain a certain temperature and humidity regime that allows people inside the apparatus to live and work. The work examines heat exchange processes occurring in closed-loop hardware systems. It is assumed that the considered network is filled with refrigerant (liquid, gas, air, etc.) and consists of flow line, structural elements, volumes, valve, regulator and mixer - distributor. In such networks, systems of differential equations (ordinary and special derivatives), as well as an algorithm for automatic construction of mathematical models of heat transfer described by numerical schemes have been developed. A special methodology and algorithm have been developed for solving this type of problems. During the solution, two methods were used and the obtained results were compared. During the solution, obvious and non-obvious schemes were used, and the most stable scheme was chosen among them.
