PURPOSE: A cooling method and a cooling system by using decompressed latent heat are provided to evaporate liquid forcibly in lower temperature than outdoor temperature by decompressing safe and economical liquid. CONSTITUTION: Corrugated fins(13) are formed on a refrigerant reservoir(10) for efficient heat exchange. A water supply pipe(12) is connected to a side of the refrigerant reservoir to receive refrigerant from a refrigerant supplying tube(11) to supply refrigerant selectively. The refrigerant reservoir is not corroded by refrigerant. A cooling pipe(20) is connected to the refrigerant reservoir, being long enough to increase contacting area of heat for evaporated refrigerant. Corrugated fins(21) are formed to an outer surface of the cooling pipe to increase heat exchanging efficiency. A vacuum pump(30) is installed to one side of the cooling pipe to lower boiling point of refrigerant to evaporate refrigerant after decompressing the refrigerant reservoir forcibly under atmosphere pressure. A pressure measuring pipe(40) is installed between the refrigerant reservoir and the cooling pipe to measure a decompressing condition. Thereby, cooling efficiency is increased by using high latent heat liquid and producing cost is reduced.
