Abstract

PURPOSE:To increase a height size of a freezing unit, reduce its thickness size, increase a volume of a freezer unit or improve a transportation efficiency by a method wherein the height size of the freezing unit is set within a specified numeral value range in respect to a height size of a high-cube type freezer unit larger than an ISO specified value. CONSTITUTION:A freezing unit 200 is installed at an end wall 2 in a freezing container 1A for use in marine transportation. In this case, the freezing container 1A is constructed into a high-cube type larger than an 180 specified value. Then, an inner or outer partition wall 41 or a condensor section 42 at an outer lower central part is formed in the freezing container 1A. In this case, a height size (h) of the freezing unit 200 is set to a value of h/H=0.9+ or -0.03 in respect to a height size H of the freezing container 1A. With such an arrangement, the height of the freezing unit 200 is increased and its thickness is reduced, thereby a dead space is prevented from being generated between an upper part and a lower part of the freezing unit and thus it is possible to increase a volume of the freezer or a transportation efficiency.

During operation of the refrigerating unit 100, the gas refrigerant discharged from the compressor 3 enters the water cooling condenser 5 or the air cooling condenser 4 and is condensed and liquefied there. The liquid refrigerant enters the expansion valve 9 via the dryer 7 and the strainer 8 and is throttled there to undergo adiabatic expansion to become a gas-liquid two-phase refrigerant. This refrigerant enters the evaporator 10, where it evaporates and vaporizes by cooling the air in the refrigerator. Then, this gas refrigerant returns to the compressor 3 via the accumulator 13.
