A heat storage material composition contains sodium acetate, water, and an organic compound comprising a hydrophobic group and a hydrophilic group. A weight ratio R (sodium acetate/water) of the sodium acetate to the water is 57/43 or less. A concentration Ws of the sodium acetate in three components of the sodium acetate, the water, and the organic compound comprising a hydrophobic group and a hydrophilic group is 52% by weight or more. A concentration Wa of the organic compound comprising a hydrophobic group and a hydrophilic group in the three components is 1% by weight or more.

The present invention relates to coolants for cooling systems in electric vehicles having fuel cells and/or batteries, preferably for motor vehicles, particularly preferably for passenger cars and commercial vehicles (known as light and heavy duty vehicles), based on alkylene glycols or derivatives thereof, which comprise additional corrosion inhibitors for improved corrosion protection in addition to specific azole derivatives.

Antifreezes are provided for deployment in wet sprinkler systems located in cold environments. The antifreezes allow for the wet sprinkler system to be actuated under temperatures below 32° F. Wet sprinklers, sprinkler systems, methods of providing for the control, suppression and/or extinguishment of a fire that occur in a cold environment, and methods of preventing wet sprinklers from freezing also are provided. The sprinklers, sprinkler systems and methods can be used in residential, commercial and storage settings.
