1. A heat exchanger core comprising:
(a) a first chamber comprising
(i) a first chamber body having a first wall and a second wall which are substantially parallel, wherein the first wall of the first chamber comprises an air inlet and an air outlet, and wherein the first chamber body extends between the air inlet and the air outlet, and wherein a portion of the first wall separates the air inlet and the air outlet,
(ii) a first heat exchange coil proximal to the air inlet and inclined with respect to the air inlet, wherein the first heat exchange coil slopes from the first wall of the first chamber adjacent to the air inlet to the second wall of the first chamber;
(b) a second chamber comprising
(i) a second chamber body having a first wall and a second wall which are substantially parallel, wherein the first wall of the second chamber body comprises an air inlet and an air outlet, and wherein the second chamber body extends between the air inlet and the air outlet, and wherein a portion of the first wall separates the air inlet and the air outlet,
(ii) a second heat exchange coil proximal the air inlet and inclined with respect to the air inlet, wherein the second heat exchange coil slopes from the second wall of the second chamber proximal the air inlet to the first wall of the second chamber, wherein the second wall of the second chamber is arranged in parallel in a back-to-back arrangement with the second wall of the first chamber, and wherein the air inlet for the first chamber is substantially opposite the air inlet for the second chamber, and wherein the air outlet for the first chamber is substantially opposite the air outlet for the second chamber in the back-to-back arrangement; and wherein
(c) the first heat exchange coil and the second heat exchange coil are connected to form a circuit for circulating refrigerant between the first heat exchange coil and the second heat exchange coil, wherein the circuit further comprises a compressor unit located within the second chamber body.
