Air conditioner having angled heat exchangers

An air conditioner comprising:

• a frame at least partially defining an air inlet and an air outlet, the frame including an upper end, a lower end opposite the upper end, and a longitudinal axis that extends through the upper end and the lower end, the lower end configured to support the frame on a support surface such that the longitudinal axis is perpendicular to the support surface;
• a fan operable to generate an airflow that moves in an airflow direction from the air inlet to the air outlet;
• and
• a 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 and 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,
• wherein a first heat exchanger angle is defined between the longitudinal axis of the heat exchanger and the longitudinal axis of the frame, and
• wherein the first heat exchanger angle is between about 3 degrees and about 20 degrees.

A modular air conditioner system comprising:

• a fan operable to generate an airflow;
• first and second sets of heat exchangers, each heat exchanger of the first and second sets oriented at no less than about 3 degrees and no greater than about 20 degrees from a vertical plane and having an air inlet face into which the airflow enters the heat exchanger, and an air outlet face opposite the air inlet face and from which the airflow exits the heat exchanger;
• a frame at least partially defining an air inlet and an air outlet, the frame including
• an upper end,
• a lower end opposite the upper end,
• a front,
• a rear opposite the front,
• lateral sides extending between and connecting the front and rear;
• an interior defined at least in part between the front and the rear of the frame and within which the heat exchangers are located,
• a door at the front through which access to the interior of the frame is provided;
• a first modular configuration in which the frame has a first width defined by and between the lateral sides of the frame and in which only the first set of heat exchangers is installed and in which the heat exchangers of the first set are arranged side-by-side with the air inlet and outlet faces of each heat exchanger substantially facing the lateral sides of the frame;
• and
• a second modular configuration in which the frame has a second width that is defined by and between the lateral sides of the frame and that is greater than the first width to accommodate both the first and second sets of heat exchangers, wherein in the second configuration the heat exchangers of the first and second sets are arranged side-by-side with the air inlet and outlet faces of each heat exchanger substantially facing the lateral sides of the frame.

An air conditioner comprising:

• a frame at least partially defining an air inlet and an air outlet, the frame including an upper end, a lower end opposite the upper end, a front, a rear opposite the front, opposite lateral sides extending between and connecting the front and the rear to define a width of the frame, and a longitudinal axis that extends through the upper end and the lower end, the lower end configured to support the frame on a support surface such that the longitudinal axis is perpendicular to the support surface;
• a fan operable to generate an airflow that moves in an airflow direction from the inlet to the outlet;
• and
• a plurality of heat exchangers each 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 and between the air inlet face and the air outlet face, each heat exchanger configured to transfer heat between the airflow and a cooling medium,
• wherein each heat exchanger is inclined with respect to the longitudinal axis of the frame;
• and
• wherein the heat exchangers are arranged side-by-side with the air inlet and outlet faces of each heat exchanger substantially facing the lateral sides of the frame, and wherein the plurality of heat exchangers includes at least one heat exchanger per 350 millimeters of width across the frame.
