Abstract
An outdoor heat exchanger coil has a fan on one side thereof for forcing ambient air through the coil and a partition on the other side thereof. The partition is placed relatively close to the coil to thereby define a channel which allows the flow of ambient air therethrough without any substantial decrease in system capacity or airflow. A comparison between the channel width and the channel length is made to define the limits of minimal separation between the coil and the partition.
Claims12
In the air conditioning system having an outdoor heat exchanger coil, an associated fan for forcing the flow of ambient air between adjacent tubes therein, and an enclosing housing containing said coil and said fan, a wall structure comprising:
- a partition contained within said housing and disposed on the opposite side of said coil from the fan, said partition being in substantial parallel relationship with a substantial portion of the coil and forming therewith an elongated channel having a length, a width and an open end in direct fluid communication with the space exterior to said housing for conducting the flow of air along its length between the edges of said partition and central portions thereof to facilitate the passing of ambient air through the coil, the channel width as defined by the distance between said partition and said coil being less than 12 inches.
An improved air conditioning outdoor heat exchanger structure comprising:
- a plurality of tubes aligned in substantial parallel spaced relationship to define a coil having an air entrance side and an air exit side;
- a fan for circulating air from said air entrance side through the spaces between said tubes and out said air exit side;
- an enclosing housing containing said coil and said fan;
- and
- a wall contained within said housing and disposed in substantial parallel relationship with a substantial portion of one of said sides to form, with said substantial portion, an elongate channel having a length and a width and an open end in direct fluid communication with the space exterior to said housing to conduct the flow of air along its length to pass through said coil, the channel width as defined by the distance between said wall and said coil being less that 12 inches.
