Реферат: A REFRIGERATION DEVICE INCLUDES A THERMAL INSULATION CASE DEFINING AN INTERIOR SPACE THEREIN. A HEAT EXCHANGER COMPRISED OF A COIL OF THERMALLY CONDUCTIVE TUBES IS ARRANGED IN THE INTERIOR SPACE. A COOLANT, SUCH AS LIQUIDIZED NITROGEN, IS FILLED IN THE TUBES OF THE HEAT EXCHANGER FOR ABSORBING HEAT FROM THE INTERIOR SPACE WHEN IT EVAPORATES WHEREBY TEMPERATURE INSIDE THE INTERIOR SPACE IS QUICKLY REDUCED AND SUBSTANCES PLACED IN THE INTERIOR CAN BE QUICKLY FROZEN.(FIG 2)
