Alternatively, a facility can use ‘off-peak’ energy rates which happen to be lessen at night to supply ice, which may be integrated right into a making’s cooling system to reduce demand for energy during the day. A patented cold thermal energy storage system from O-Hx takes advantage of ice slurry https://purethermal.co.uk/media-news/pure-thermal-webinar-can-icebat-cold-thermal-energy-storage-provide-an-alternative-cooling-design-option/
