A holding chamber may be supplied from a storage vessel system with a cryogen, such as liquid CO2 or it may itself be large enough to take the place of a separate storage vessel. The temp. within the holding chamber is reduced to the triple point or below to form a refrigeration reservoir of solid cryogen, as by removing vapour from the chamber to cause evaporation or by employing mechanical refrigeration. The stored cooling power of the reservoir is later employed to meet a large or a periodic refrigeration demand and is after-wards replenished over a number of hours, pref. during a period of non-peak electric demand.
