Patent ID: 7921659

Claim:
A refrigeration system comprising: a frame for securing in an opening of a conditioned space; a mounting for rigidly connecting to the frame; removable connectors selectively connecting and disconnecting the mounting from the frame in the opening of the conditioned space; a flexible monoblock refrigeration unit having: a first heat exchanger module for rigidly connecting to the mounting and having a first heat exchanger for modulating temperature of the conditioned space; a compressor module for rigidly connecting to the mounting; a refrigerant control assembly connected to the compressor module; a second heat exchanger module for rigidly connecting to the mounting; a first set of refrigerant connections flexibly connecting the compressor module and the refrigerant control assembly with the first heat exchanger module for communicating refrigerant between the compressor module and the first heat exchanger module; and a second set of refrigerant connections flexibly connecting the compressor module and the refrigerant control assembly to the second heat exchanger module; wherein the conditioned space is a cargo container having an interior which is the conditioned space, and further comprising an internal foraminous cover extending inward in the interior of the cargo container from near the opening and preventing access to cargo in the container when the refrigeration unit is removed and replaced; further comprising a coil in the first heat exchanger module, and an internal fan mounted on the internal cover for moving air in the cargo container through the coil.
