Cryogenic refrigeration of goods

摘要

Apparatus for refrigerating goods in a container comprising means for storing (2,30) a cryogenic fluid (4) and means (6,10,28) for discharging the fluid into the container (22) in order to reduce the temperature therein, characterised in that the storing means (2,30) is adapted to operate at atmospheric pressures but not at pressures substantially greater than atmospheric. Such a system provides a single and inexpensive means for refrigerating goods in a transportable container (22), which may be divisible into smaller compartments (24), and may also be provided with eutectic plates to act as a thermal "buffer" whenever the container (22)/a compartment (24) is opened for loading/unloading.
