Modular refrigeration unit and cabinet systems therewith
First Claim
1. A foodstuffs refrigerator comprising an integral cabinet having at least two zones in separate compartments including:
- a. a confined food zone in a first compartment in which foodstuffs are to be located and within which zone a controlled refrigeration temperature is maintained and which zone is free of mechanical equipment; and
,b. a separate equipment zone in a separate compartment adjacent to the food zone containing a modular refrigeration unit which is independently removeable from the compartment of the equipment zone and which unit provides the controlled temperature for the food zone;
said modular refrigeration unit integrally including compressor, condenser, evaporator, metering means and means for connecting said components in the relationship of a refrigeration cycle, and an air circulating means to provide a flow of air to and from the evaporator means of the refrigeration unit;
and in which the food zone and equipment zone are connected by duct means between the two compartments for directing the flow of air provided from the air circulating means of the modular refrigeration unit contained within the equipment zone to a predetermined area of the food zone, and for directing a flow of air from the food zone to the air circulating means, whereby air is recirculated from the food zone through the evaporator means of the refrigeration unit in a cyclical manner.

Abstract
A modular refrigeration unit which is independently removable from an equipment zone in a foodstuffs refrigerator is described. The modular refrigeration unit integrally includes compressor, condenser, evaporator, metering means and means for connecting said components in the relationship of a refrigeration cycle, and an air circulating means to provide a recirculating flow of air between the refrigeration unit and the food zone of the refrigerator. The modular unit may be used in a system of standardized refrigerators at multiple installations at separate locations, in which the refrigeration system of each unit is separately removeable from each unit and interchangeable with the others. Service and maintenance of the refrigerator is facilitated and useable storage space and sanitation in the food zone is increased.

4. A system of standardized refrigerator units utilized at multiple installations at separate locations in which each refrigerator unit contains separate compartments which define a first food zone which is free of mechanical equipment and a second equipment zone in which the refrigeration system of each unit is contained within the equipment zone and is separately removeable from the refrigerator unit and interchangeable with the refrigeration system of other units, and in which the refrigeration system of each unit integrally includes in a standardized module, a compressor, condenser, evaporator and metering means connected together in a refrigeration cycle for providing a controlled refrigeration temperature, and circulating means for providing a flow of fluid air to the evaporator means, to provide a controlled refrigeration temperature to the fluid air, and in which the refrigeration system of the unit is engageable with duct means for connecting the flow of fluid air provided by the circulating means to the food zone within a refrigerator unit.
