The hybrid cooling system of vapor compression system and naturally circulating coolin system using R-410a for indoor mobil tele-communication center(IMTC) is developed and its performance is experimentally studied. Its results are summarized as follows. First, cooling capacity of naturally circulating cooling system is proportional to indoor and outdoor temperature difference and it has max. 4,550 kcal/h at indoor and outdoor air temperature difference 15℃. Second, heat exchangers of evaporator and condenser should be designed and constructed to be able to get maximum refrigerant capacity by naturally circulating force and to enhance heat transfer by refrigerant. Third, cooling capacity of hybrid cooling system has optimum operating point according to refrigerant charging capacity and refrigerant charging capacity of naturally circulating cooling system is 30~50% more than vapor compression refrigeration system.
