An apparatus for heating, ventilation and/or air conditioning of an interior space includes a heat exchanger core and a heating/cooling device in fluid connection with the heat exchanger core. A recirculation port is arranged between a supply air chamber and an outside air chamber. A damper is adapted to move between a first position in which the damper blocks the recirculation port and a second position in which the recirculation port is unblocked. When the damper is in the second position, at least a portion of supply air is guided to flow from the supply air chamber through the outside air chamber to the heat exchanger core so as to defrost the heat exchanger core.

1. An apparatus for heating, ventilation and/or air conditioning of an interior space of a structure, the apparatus comprising: a housing comprising an exhaust air inlet, an exhaust air outlet, an outside air inlet, and a supply air outlet;a heat exchanger core arranged in the housing and comprising
1. An apparatus for heating, ventilation and/or air conditioning of an interior space of a structure, the apparatus comprising: a housing comprising an exhaust air inlet, an exhaust air outlet, an outside air inlet, and a supply air outlet;a heat exchanger core arranged in the housing and comprising a first side and a second side segregated from the first side;an exhaust air chamber arranged between the exhaust air inlet and the first side of the heat exchanger core;an outside air chamber arranged between the outside air inlet and the second side of the heat exchanger core;a heating/cooling device in fluid connection with the second side of the heat exchanger core;a supply air chamber arranged between the heating/cooling device and the supply air outlet;a recirculation port arranged between the supply air chamber and the outside air chamber; anda damper mechanism that is a single device that facilitates an approximately simultaneous opening of the recirculation port and closing of the outside air inlet, and vice versa, the damper mechanism comprising a damper adapted to move between a first position in which the damper blocks the recirculation port and a second position in which the damper blocks the outside air inlet and the recirculation port is unblocked,wherein, during operation in a defrost mode when the damper is in the second position, the exhaust air is guided to flow through the exhaust air inlet and the exhaust air chamber to the first side of the heat exchanger core, the outside air is blocked from flowing through the outside air inlet, and at least a portion of supply air is guided to flow from the supply air chamber through the recirculation port and the outside air chamber to the second side of the heat exchanger core, so as to defrost the heat exchanger core. 2. The apparatus of claim 1, wherein the supply air chamber is separated from the outside air chamber by a front panel, and the recirculation port is disposed in the front panel. 3. The apparatus of claim 2, wherein the damper is disposed in the outside air chamber. 4. The apparatus of claim 3, wherein the damper pivots between the first and second positions. 5. The apparatus of claim 4, wherein the damper mechanism further comprises a motor and a control arm, and the damper is coupled to the motor by the control arm, the motor and the control arm being adapted to move the damper between the first and second positions. 6. The apparatus of claim 5, wherein the damper is biased to the second position. 7. The apparatus of claim 1, wherein one of the exhaust air outlet and the exhaust air inlet is arranged on a side of the housing. 8. The apparatus of claim 7, wherein the one of the exhaust air outlet and the exhaust air inlet is disposed laterally adjacent to the heat exchanger core. 9. An apparatus, comprising: a heat exchanger core having a first side and a second side segregated from the first side;an exhaust air inlet in fluid connection with the first side of the heat exchanger core, and adapted to guide exhaust air to the first side of the heat exchanger core;an exhaust air outlet in fluid connection with the first side of the heat exchanger core, and adapted to guide the exhaust air from the first side of the heat exchanger core to be expelled outside of an interior space;an outside air inlet in fluid connection with the second side of the heat exchanger core, and adapted to guide outside air through an outside air chamber to the second side of the heat exchanger core, so as to exchange heat between the exhaust air flowing through the first side of the heat exchanger core and the outside air;a heating/cooling device in fluid connection with the second side of the heat exchanger core, and adapted to condition the outside air to form supply air, and guide the supply air to a supply air chamber;a supply air outlet in fluid connection with the supply air chamber, and adapted to guide the supply air from the supply air chamber to be delivered to the interior space;a recirculation port arranged between the supply air chamber and the outside air chamber; anda damper disposed within the outside air chamber and adapted to pivot between a first position in which the damper blocks the recirculation port and the outside air inlet is unblocked, and a second position in which the damper blocks the outside air inlet and the recirculation port is unblocked,wherein, during operation in a defrost mode when the damper is in the second position, the exhaust air flows to the first side of the heat exchanger core, the outside air is blocked from flowing to the second side of the heat exchanger core, and at least a portion of the supply air is guided to flow from the supply air chamber through the recirculation port and the outside air chamber to the second side of the heat exchanger core, so as to defrost the heat exchanger core. 10. The apparatus of claim 9, wherein the supply air chamber is separated from the outside air chamber by a front panel, and the recirculation port is disposed in the front panel. 11. The apparatus of claim 9, wherein the damper is biased to the second position. 12. An apparatus, comprising: a heat exchanger core having a first side and a second side segregated from the first side;an exhaust air chamber for guiding exhaust air to the first side of the heat exchanger core;an outside air chamber for guiding outside air from an outside air inlet to the second side of the heat exchanger core;a heating/cooling device configured to condition the outside air to form supply air;a supply air chamber for guiding the supply air from the heating/cooling device to be delivered to an interior space;a recirculation port arranged between the outside air chamber and the supply air chamber; anda damper mechanism that is a single device that facilitates an approximately simultaneous opening of the recirculation port and closing of the outside air inlet, and vice versa, the damper mechanism comprising a damper that is movable between a first position in which the outside air inlet is open and the recirculation port is closed, and a second position in which the outside air inlet is closed and the recirculation port is open,wherein, during operation in a normal mode, the damper is in the first position, the exhaust air flows to the first side of the heat exchanger core, and the outside air flows to the second side of the heat exchanger core, andwherein, during operation in a defrost mode, the damper is in the second position, the exhaust air flows to the first side of the heat exchanger core, the outside air is blocked from flowing to the second side of the heat exchanger core, and at least a portion of the supply air is guided to flow from the supply air chamber through the recirculation port and the outside air chamber to the second side of the heat exchanger core, so as to defrost the heat exchanger core. 13. The apparatus of claim 12, wherein the supply air chamber is separated from the outside air chamber by a front panel, and the recirculation port is disposed in the front panel. 14. The apparatus of claim 12, wherein the damper is biased to the second position.
