Energy consumption of electric equipment of free cooling system can't be considered small. On the basis of multiple calculations of seasonal expenses of the electric power it is shown that expediency of transition to free cooling in Moscow conditions at external air temperature is near +9 °8. But, an economic comparison of the results found out the profit of transition to a free cooling, which shall be determined by the dry freezing agent size to be chosen for 100% of a condenser refrigeration load.

Keywords: air-conditioning; cooling machine; sensible-heat cooler; electrical energy; calculation.
