Abstract
Abstract A System and Cold Cabinet Server therefor to condition pre-packaged foods and to maintain them at serving temperature during storage and for customer access. A structural relationship of means is provided in cooperatively related bin type cabinets to combine the inherent principles of convection, absorption and recirculation to maximum advantage and to the end that heat induction from the surrounding atmosphere is minimized despite the completely open and accessible bin configuration. The Cold Cabinet is a self-sufficient entity provided with a replaceable refrigeration unit supplied with power such as an electrical plug-in, and is completely mobile; and adapted to be quickly assembled in service lines that are readily modified or broken down for storage.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
235 words
A Cold Cabinet for conditioning prepackaged foods and the like to maintain refrigeration of the same and including; a bin type cabinet with insulated side and end and bottom panels, the bottom panel being stepped with a bulkhead disposed between the end panels dividing the cabinet into an equipment chamber exterior thereto and a recirculation chamber interior thereto and there being an opening through the bulkhead, a baffle within the cabinet and disposed between the end panels in spaced relation to the bulkhead and there being an opening through the baffle, said openings in the bulkhead and baffle being aligned, an upwardly open well complementary to and depending into the cabinet with side and end and bottom walls in spaced relation to the aforementioned body panels respectively, the bottom wall of the well being engaged with and carrying the baffle dividing the space between the cabinet panels and well walls into an air intake means vented from the well and an air recirculating means vented into the well, and a replaceable refrigeration unit comprised of closure means disengageable in the bulkhead opening and an evaporator disengageable in the baffle opening and a blower means having a motor shaft with an exterior refrigeration cooling fan in said equipment chamber and extending into said recirculation chamber with an interior recirculating fan for moving air from the intake means and through the evaporator and into the recirculating means.

Claim 3
Dependent Claim
45 words
The Cold Cabinet as set forth in claim 1, wherein the blower means has a motor within the equipment chamber and a shaft extending through the closure and to drive the interior recirculating fan for moving air from the intake means and through the evaporator.
Claim 4
Dependent Claim
59 words
The Cold Cabinet as set forth in claim 1, wherein the refrigeration unit has a chassis carried together with the said closure and supporting a compressor and a condenser exteriorly and cooled by the blower means with its shaft extending through the closure and to the interior recirculating fan for moving air from the intake means through the evaporator.
Claim 5
Dependent Claim
33 words
The Cold Cabinet as set forth in claim 1, wherein a thermostat control of said refrigeration unit extends through said closure and is exposed to the refrigerated air within the said recirculation plenum.
Claim 6
Dependent Claim
82 words
The Cold Cabinet as set forth in claim 1, wherein a thermostat control of said refrigeration unit extends through said closure for exposure to the refrigerated air within the said recirculation plenum, wherein the refrigeration unit has a chassis carried together with the said closure and supporting a compressor and a condenser exteriorly and cooled by the blower means with its shaft extending through the closure and to the interior recirculating fan for moving air from the intake means through the evaporator.
