Beschreibung
Zusammenfassung:	Disclosed are a method and a device for preventing contamination of a fluid by a cooling/heating medium in a fluid storage tank wherein the temperature is controlled by the cooling/heating medium. Provided are a method and a device for the method, wherein the temperature of a fluid storage tank (2) is controlled using a liquid cooling/heating medium by flowing the cooling/heating medium within a sealed pressure resistant jacket (4) provided on the outside of a wall surface of the fluid storage tank (2) placed under a constant pressure, and the cooling/heating medium flows in the sealed pressure resistant jacket (4) at a pressure equal to or lower than a pressure x (atm), and preferably lower than x (atm), of the inside of the fluid storage tank (2), so as to prevent contamination of the fluid by the cooling/heating medium in the storage tank (2).
