Abstract: A portable, modular refrigeration unit is disclosed. The portable, modular refrigeration unit comprises an insulated structure including a floor, a roof, and a plurality of wall panels. Latches contained in the wall panels interconnect the wall panels to form a continuous wall disposed between the floor and the roof. A U-shaped channel is adapted for supporting a refrigeration evaporator unit within the structure. A frame horizontally supports the floor of the structure above the ground. The frame extends beyond the floor and is adapted to support a refrigeration compressor unit coupled to the evaporator unit.
