Key words: finning, heat exchange, condenser, seasonally acting cooler unit, permafrost soil.
The attempt to define the coefficient of heat transfer from the surface of the condenser of seasonally acting cooling unit is made. The calculation takes into account features of the geometric parameters of the condenser (fin size and spacing, the size of the pipe), and also the finning material. According to the results of the developed technique the bundled software, which allows to simulate the processes of condenser heat exchange and to determine the most optimal finning design parameters, is created.
