Dampers placed on the half face of the inlet and the outlet of side-by-side airflow energy recovery sections used as recirculation path

A method of providing recirculation capabilities using an air handler with a core, comprising:

• opening a first damper;
• receiving vented indoor air from a controlled space through a first tunnel;
• channeling a first portion of the vented indoor air from the first tunnel to a second tunnel through a first opening, a first recirculation path, and the first damper;
• and
• returning the first portion of the vented indoor air from the second tunnel into the controlled space, wherein
• the air handler has a housing that includes a faceplate, a first panel, a second panel, a third panel, and a fourth panel,
• a septum protrudes into the housing from a first side of the faceplate,
• the housing contains the core having a second edge connected to the first panel, a third edge connected to the second panel, a first edge connected to the septum, a first plate connected to the third panel, and a second plate connected to the fourth panel,
• the first tunnel connects to the faceplate at a first area of a second side of the faceplate, wherein the second side is opposite to the first side of the faceplate,
• the second tunnel connects to the faceplate at a second area of the first side of the faceplate, wherein the second area is disjointed from the first area,
• the first damper is disposed in the second area on the faceplate,
• the first opening is disposed in the first area on the faceplate, and
• the first recirculation path is defined by the first panel, the faceplate, the third panel, the fourth panel, the septum, and the core.
