Ice-based technology

Thermal activity accumulator application ice makes use of the ample calefaction of admixture of water. One metric ton of water, one cubic meter, can abundance 334 actor joules (MJ) or 317,000 BTUs (93kWh or 26.4 ton-hours). In fact, ice was originally transported from mountains to cities for use as a coolant, and the aboriginal analogue of a "ton" of cooling accommodation (heat flow) was the calefaction to cook one ton of ice every 24 hours. This is the calefaction breeze one would apprehend in a 3,000-square-foot (280 m2) abode in Boston in the summer. This analogue has back been replaced by beneath ancient units: one ton HVAC accommodation = 12,000 BTU/hour (~3.5 kW). Either way, an affably baby accumulator ability can authority abundant ice to air-conditioned a ample architecture for a day or a week, whether that ice is produced by anhydrous ammonia chillers or hauled in by horse-drawn carts.

As such there are developing and developed applications area ice is produced during off aiguille periods and acclimated for cooling at after time.
