ABSTRACT:
Disclosed is a cooling method and a system therefor. The cooling system is provided with a refrigerant circuit, comprising a small-capacity primary air-cooled condenser to which a vaporized refrigerant compressed in a compressor is supplied; a water-cooled condenser to which the refrigerant fed from said primary air-cooled condenser is supplied; a small-capacity secondary air-cooled condenser to which the refrigerant fed from said water-cooled condenser is supplied; an expansion means to which the liquefied refrigerant fed from said secondary air-cooled condenser is supplied; and an evaporator to which the refrigerant after an abrupt pressure reduction by said expansion means is supplied. According to the cooling system of the invention, consumption of the cooling water in the water-cooled condenser can greatly be reduced, and the running cost of the system can also easily be reduced.
