1. A shock freezing cabinet comprising:
a housing,
a food freezing compartment,
an upper and a lower chamber respectively accommodating a first fan and a second fan installed therein,
an evaporator and a condenser,
a grill mounted in a front lower part of the housing in front of the lower chamber, the grill having the condenser and the second fan mounted behind the grill in an inner space of the lower chamber,
wherein:
the evaporator and the first fan are mounted inside the upper chamber,
the evaporator is of a sectional type in the form of pipes that are round in cross-section,
the evaporator is located along a back wall symmetrically on both sides of the upper chamber relative to a vertical symmetry axis of the upper chamber in a same plane with the first fan,
the evaporator pipes are positioned with equal pitch as per a zigzag pattern in parallel rows,
the first fan is mounted between the evaporator sections,
behind the first fan on the upper chamber back wall along a height of the back wall and along an axis coinciding with a fan axis of the first fan and in rear corners of the upper chamber, there are air flow deflectors with protruding walls positioned at negative angles to the fan axis directed to the back wall configured to reflect and re-direct air flows from the first fan so as to eliminate “stagnant” areas and to ensure circulation of cold air mass directed to cooled food,
the housing further mounts a compressor, a receiver, a dehydrating filter, and solenoids.
