Abstract
A cooling unit comprising: an interior space; a door separating the interior space from air external to the cooling unit, wherein the door comprises a transparent window; an air curtain system having an air egress and an air-recovery ingress, wherein the air curtain system produces an air curtain between the air egress and the air-recovery ingress, the air curtain being within the interior space and spaced from the door; and an air curtain guide for guiding flow of air within the air curtain, wherein the air curtain guide is within the interior space. A method of reducing condensation on a transparent window in a door of a cooling unit is also provided.
Claims20
A cooling unit comprising:
- an interior space;
- a door separating the interior space from air external to the cooling unit, wherein the door comprises a transparent window having an uppermost edge, a lowermost edge and an inner surface facing the interior space;
- a plurality of shelves disposed within the interior space, each shelf of the plurality of shelves including a front edge that faces the door;
- an air curtain system having an air egress and an air-recovery ingres;
- an air curtain produced by the air curtain system between the air egress and the air-recovery ingress, the air curtain being within the interior space, and wherein the air curtain is spaced from the inner surface of the window by an access space that extends along an entire length of the window between the uppermost edge and the lowermost edge;
- and
- a plurality of air curtain guides each including an airfoil positioned between and spaced from the front edge of a respective shelf of the plurality of shelves and the inner surface of the window, wherein each airfoil is configured to direct the flow of air within the air curtain away from the door when the door is in a closed position such that misting of the transparent window is reduced by reducing a cooling effect on the door.
An apparatus, comprising:
- a transparent window in a door of a cooling unit, where the door is moveable between an open position and a closed position;
- a shelf positioned within an interior space of the cooling unit and including a front edge that faces the door;
- an air curtain system of the cooling unit;
- an air curtain produced by the air curtain system between an air egress and an air-recovery ingress of the air curtain system in the interior space of the cooling unit, wherein the air curtain extends along an entire length of the window;
- and
- an air curtain guide located between the front edge of the shelf and the window and spaced from the front edge of the shelf, wherein the air curtain guide is configured to guide flow of air within the air curtain such that the air curtain is spaced from the window of the door by an access space that extends along the entire length of the window when the door is in the closed position.
