THERMAL STORAGE UNIT WITH COIL EXTENSION DURING MELT

摘要

Method and apparatus for thermal storage improved to deliver cold liquid refrigerant during a supply cycle by freezing storage liquid envelopes only on tubes defining refrigerant flow paths during an ice production and storage cycle and extending the effective flow paths during the supply cycle through supplementary conduits immersed in free storage liquid which is chilled by the exterior of the frozen envelopes.
