The article presents a new method for the comparative analysis of the effectiveness of a vapor-liquid compression cooling system and traditional solutions based on single-phase liquid and air cooling, while taking into account the combination of cooling capacity factors, the power expended on this, depending on the ambient temperature. As a result of numerical simulation, it was proved that the total power consumption CS ∑ N c s ′ for ensuring the operability of the vapor-liquid compression cooling system with increasing ambient temperature decreases relative to the similar total power consumption ∑ N CS for a system using traditional cooling methods. With increasing mass flow rate and temperature of the cooling air, the relative power consumption ∑ N C O ′ / ∑ N C O for the functioning of the cooling systems under consideration becomes less than the relative energy indicator of the quantities of heat removed Q И / Q CO from the cooled object.
