Abstract
Abstract A dietary module suitable for moving food about a hospital. The module has an opening on one end for cold air from a portable refrigeration unit having an opening compatible with the opening in the module. The refrigeration unit can be connected to the module when the module is stationary. The refrigeration unit has a refrigeration compressor, condenser, evaporator and fan for circulating air through the module. The module can be quickly disconnected from the refrigeration unit and moved to a distant point where it can be connected to another refrigeration unit for use.
