Abstract: A refrigeration apparatus for a transport container has a partition to divide the interior of a box, which is mounted on the front wall of a container, into two compartments. In one of the compartments is disposed a refrigeration assembly including an evaporator, an evaporator fan, a condenser, a condenser fan and a refrigerant compressor, on the other hand, in the other one of the compartment is disposed a common mount on which a generator assembly including an engine, an engine radiator, a radiator fan and a generator in in-line relation is mounted in such a manner that the generator assembly may be installed into or removed from the box as one unit. The refrigeration assembly and the generator assembly are thermally isolated from each other by the partition, so that an exhausted warm air from one assembly does not heat the other assembly.
