    摘要: The lower-most temperature of the thermal mass in a chilled water stratified storage tank is lowered without reducing its density by the addition of sodium nitrite and sodium nitrate, alone or in combination, preserving thermal stratification so that both warm and chilled water may be stored in the tank, a benefit not previously obtained without the use of chemicals damaging to the environment. A solution of sodium nitrite and sodium nitrate lowers the freezing point of the cooling water to -13.2.degree. C. (8.3.degree. F.) yet still permits the chilled water to stratify in the storage tank.

    摘要: The lower-most temperature of the thermal mass in a chilled water stratified storage tank is lowered without reducing its density by the addition of sodium nitrite and sodium nitrate, alone or in combination, preserving thermal stratification so that both warm and chilled water may be stored in the tank, a benefit not previously obtained without the use of chemicals damaging to the environment. A 7% solution of sodium nitrite and sodium nitrate in a 2 to 1 ratio lowers the freezing point of the cooling water to -3.75.degree. C. (25.25.degree. F.) yet still permits the chilled water to stratify in the storage tank.
