Abstract

A modular refrigeration system having an evaporator, a condenser, and a compressor fluidly connected by a plurality of conduits comprises a one-piece base plate. The evaporator, condenser, and compressor are mounted to the base plate. A
drain pan is integrally formed in the base plate. The drain pan is located beneath the compressor. A drain basin is integrally formed in the base plate located beneath the evaporator. The basin and the drain pan are fluidly connected such that condensate collects in the drain pan.

Claims

1. A modular refrigeration system having an evaporator, a condenser, and a compressor fluidly connected by a plurality of conduits, the modular refrigeration system, comprising:
a one-piece base plate, the evaporator, condenser, and compressor mounted to said base plate;
a drain pan integrally formed in said base plate, said drain pan located beneath the compressor; and a drain basin integrally formed in said base plate located beneath the evaporator, said basin and said drain pan fluidly connected such that condensate collects in said drain pan.

2. The refrigeration system of claim 1, further comprising a channel integrally formed in said base plate, said channel fluidly connecting said basin and said drain pan.

3. The refrigeration system of claim 1, wherein the compressor further includes a discharge tube, at least a portion of said discharge tube located in said drain pan, whereby heat from the discharge tube promotes evaporation of condensate in said drain pan.

4. The refrigeration system of claim 1, wherein the condenser further includes a fan, whereby heated air directed over said drain pan by said fan promotes evaporation of condensate in said drain pan.

5. A modular refrigeration system having an evaporator, a condenser, and a compressor fluidly connected by a plurality of conduits, the modular refrigeration system, comprising:
a one-piece base plate, the evaporator, condenser, and compressor mounted to said base plate;
a drain pan integrally formed in said base plate, said drain pan located beneath the compressor, condensate collecting in said drain pan, the condenser further including a fan, whereby said fan directs air over said drain pan and the condensate evaporates;
a fan mount integrally formed in said base plate, said fan mount located beneath the evaporator;

at least one airflow passageway located in said base plate;
a cover mounted to said base plate encasing the evaporator, said fan mount and said airflow passageway located beneath said cover.

6. The refrigeration system of claim 5, further comprising a drain basin integrally formed in said base plate, said drain basin located beneath the evaporator and said cover.

7. The refrigeration system of claim 6, wherein said drain basin is fluidly connected to said drain pan, condensate from the evaporator collected in said drain basin and directed to said drain pan.

8. The refrigeration system of claim 5, wherein the compressor further includes a discharge tube, at least a portion of said discharge tube located in said drain pan, whereby heat from the discharge tube promotes evaporation of condensate in said drain pan.

9. The refrigeration system of claim 5, further comprising a chamber defined by said cover, air flowing into said chamber via a first said airflow passageway and out of said chamber via a second said airflow passageway.

10. A modular refrigeration system having an evaporator, a condenser, and a compressor fluidly connected by a plurality of conduits, the modular refrigeration system, comprising:
a one-piece base plate, the evaporator, condenser, and compressor mounted to said base plate;
at least one projection integrally formed with said base plate;
a cover mounted to said base plate encasing the evaporator, said cover engaged by said projection;
a groove formed in said cover;
a hook located on each of opposite sides of said base plate; and an elastic fastener received in said groove and engaging each said hook, whereby said cover is secured to said base plate by said fastener.

11. The refrigeration system of claim 10, wherein said cover includes a first inner layer and a second outer layer, said first layer in contact with air in the system and said second layer secured to said first layer.

12. The refrigeration system of claim 11, wherein said second layer is constructed from an insulative material.

13. The refrigeration system of claim 10, further comprising a gasket located between said base plate and said cover.

14. The refrigeration system of claim 10, wherein said cover further includes radii sized to prevent turbulent airflow beneath said cover.

15. The refrigeration system of claim 10, wherein said elastic fastener is a rubber band.

16. A method of attaching a cover for an evaporator to a base plate of a modular refrigeration system, comprising:
engaging the cover with projections extending from the base plate;
engaging a first hook formed on a first side of the base plate with an elastic fastener;
locating the elastic fastener in a groove formed in the cover; and engaging a second hook formed on a second, opposite side of the base plate with the elastic fastener, whereby the cover is secured to the base plate.
