Abstract

A cold storage material composition contains tetra-n-butylammonium bromide, water, and 1-propanol. The weight ratio of tetra-n-butylammonium bromide to water is greater than or equal to 32.5/67.5 and less than or equal to 42.5/57.5. The molar ratio of 1-propanol to water is greater than or equal to 0.02 and less than or equal to 0.042. The cold storage material composition has a fusion heat of greater than or equal to 135 J/g within a range of higher than or equal to 5 degrees Celsius and lower than or equal to 12 degrees Celsius and has a heat flow peak within a range of higher than or equal to 5 degrees Celsius and lower than or equal to 12 degrees Celsius.

Claims (10)

1 . A cold storage material composition comprising:

tetra-n-butylammonium bromide;

water; and

1-propanol, wherein

a weight ratio of the tetra-n-butylammonium bromide to the water is greater than or equal to 32.5/67.5 and less than or equal to 42.5/57.5;

a molar ratio of the 1-propanol to the water is greater than or equal to 0.02 and less than or equal to 0.042;

the cold storage material composition has a fusion heat of greater than or equal to 135 J/g within a range of higher than or equal to 5 degrees Celsius and lower than or equal to 12 degrees Celsius; and

the cold storage material composition has a heat flow peak within a range of higher than or equal to 5 degrees Celsius and lower than or equal to 12 degrees Celsius.

2 . A refrigerator including the cold storage material composition according to claim 1 .

3 . A cold-storage warehouse including the cold storage material composition according to claim 1 .
