HYDROCARBON REFRIGERATION SYSTEM WITH CONVECTION CHANNEL

摘要

A refrigeration system including a cabinet having an outer wall defining an insulated interior, an inner wall, and an insulative material disposed between the out er and inner walls. A cooling system is disposed in a space beneath the cabinet and cools the insulated interior. A convection channel is disposed between the outer and inner walls and exten ds and communicates air from an area outside an upper portion of the cabinet to the space beneath the cabinet. The channel is positioned within about 1.905 cm from the inner wall. The channel may have a plurality of different widths and may include a thermal bridge extending from the inner wall to the channel. The channel may include a primary branch extending from the upper portion of the cabinet to a junction point and a plurality of secondary branches extending from the junction point to a plurality of locations beneath the cabinet.
