Latentkaelte-Speicherverfahren und Latentkaelte-Speicher fuer ein Kaltwassernetz

DE 19938725 C UPAB: 20000718 NOVELTY - The latent heat energy cold bank for maintaining a distributed water system between 2-12 deg. C, or for providing water for use as a coolant in a chilled storage installation, has a heat conducting wall separating water from a working substance, preferably a paraffinic compound, especially n-tetradecane or n-pentadecane. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an n-tetradecane/n-pentadecane charged buffer cooling device. USE - Cooling system for water distribution systems and cold stores. ADVANTAGE - Cost effective provision of buffer cooling capacity able to supply flowing water at down to 1.5 deg. C, without the need for glycol anti-freeze addition. The paraffinic working substances are non-toxic and compatible with polypropylene and high density polyethylene pipework, as frequently used in water handling systems.
