What is claimed is: 1. A compact refrigeration system comprising: a closed vapor compression circuit having operably disposed therein, in serial order, a compressor, a first heat exchanger, an expansion device and a second heat exchanger; said first heat exchanger removing thermal energy from a working fluid circulating through said vapor compression circuit and said second heat exchanger adding thermal energy to the working fluid circulating through said vapor compression circuit, said first heat exchanger having an airflow inlet; said first and second heat exchangers being disposed within a common structure, said structure defining at least one insulating airflow passageway separating said first heat exchanger from said second heat exchanger; said insulating airflow passageway having an inlet positioned to bring ambient air from outside the structure into the insulating airflow passageway and an outlet positioned to discharge insulating airflow from the structure, said insulating airflow passageway extending along a length of the second heat exchanger, said outlet not in flow communication through said second heat exchanger; and an air moving device generating an insulating airflow through said at least one airflow passageway wherein said airflow defines a layer of insulating moving air that enters and exits said insulating airflow passageway without passing through either of said first and second heat exchangers whereby said layer of moving air provides an insulating layer between said first heat exchanger and said second heat exchanger. 2. The system of claim 1 wherein said air moving device generates a second airflow directed onto said first heat exchanger. 3. The system of claim 1 wherein said second heat exchanger includes two surfaces facing an interior of said structure, the airflow moving across both of said surfaces. 4. The system of claim 3 wherein said surfaces are oriented substantially perpendicular to one another. 5. The system of claim 1 wherein said at least one airflow passageway is defined by at least one high density heat exchange surface. 6. A method of operating a refrigeration system comprising: providing in a housing a closed vapor compression circuit having operably disposed therein, in serial order, a compressor, a first heat exchanger, an expansion device and a second heat exchanger; removing thermal energy from a working fluid circulating through said vapor compression circuit by use of said first heat exchanger; adding thermal energy to the working fluid circulating through said vapor compression circuit by use of said second heat exchanger; generating an insulating airflow stream between said first heat exchanger and said second heat exchanger such that said airflow provides a thermally insulating layer between said first heat exchanger and said second heat exchanger said insulating airflow stream flowing through said housing without passing through either of said first or second heat exchangers. 7. The method of claim 6 wherein the airflow stream has a first portion, a second portion and a third portion, the first portion being directed onto said first heat exchanger, said method comprising the further steps of: directing the second portion onto electronics of the refrigeration system; and directing the third portion along a length of said second heat exchanger. 8. The method of claim 7 wherein the second portion of the airflow remains at a substantially constant temperature until being directed onto the electronics. 9. The method of claim 8 wherein the electronics includes a power supply, said method comprising the further steps of: cooling a device by use of the refrigeration system; and providing power to both the refrigeration system and the cooled device by use of said power supply. 10. The method of claim 6 wherein a portion of the airflow is directed in a direction substantially opposite to a direction of heat conduction from said first heat exchanger to said second heat exchanger. 11. The method of claim 6, wherein the insulating airflow enters and exits the housing at substantially the same temperature. 12. The method of claim 6, wherein the airflow stream has a first layer, a second layer and a third layer, said second layer being intermediate the first and second layers, said method comprising the further steps of: directing the second layer onto electronics of the refrigeration system; and directing the third layer along a length of the second heat exchanger. 13. The method of claim 6 wherein the airflow stream has a first layer, a second layer and a third layer, said second layer being intermediate the first and third layers, and wherein the second layer remains at a substantially constant temperature. 14. The method of claim 13 wherein the first layer is directed in a direction substantially opposite to a direction of heat conduction from said first heat exchanger to said second heat exchanger. 15. The method of claim 6 wherein the airflow stream has a first layer, a second layer and a third layer, said second layer being intermediate the first and third layers, wherein the second layer enters and exits the housing at substantially the same temperature.
