AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
Claims 1-13 are cancelled.
Claims 14-25 were not reexamined.
1. An air conditioner comprising:
a frame at least partially defining an air inlet and an air outlet, the frame including an upper end and a lower end, the lower end configured to support the frame on a support surface;
a fan operable to generate an airflow that moves in an airflow direction from the air inlet to the air outlet;
a first heat exchanger including a first end adjacent the air inlet, a second end adjacent the air outlet, an air inlet face that extends between the first end and the second end, an air outlet face that extends between the first end and the second end and faces opposite the air inlet face, and a longitudinal axis that extends through the first end and the second end between the air inlet face and the air outlet face, the first heat exchanger configured to transfer heat between the airflow and a cooling medium; and
a first air filter adjacent to the air inlet face and parallel to the air inlet face,
wherein a total area of the first air filter approximately equals a total air inlet face area of the first heat exchanger,
wherein the total air inlet face area of the first heat exchanger is defined by a width and a length of the air inlet face of the first heat exchanger,
wherein a first heat exchanger angle is defined between the longitudinal axis of the heat exchanger and the airflow direction, and
wherein the first heat exchanger angle is between about 3degrees and about 20 degrees.
