Abstract
An HVAC unit including: a case defining a first aperture, a second aperture, a third aperture, and an outlet aperture, a first door rotatably attached to the case, a second door, rotatably attached to the case, and a third door rotatably attached to the case, with the first door being arranged to partially allow the exterior airflow in its closed position.
Claims20
A heating, ventilation and air conditioning unit comprising:
- a case defining a first aperture, a second aperture, a third aperture, and an outlet aperture,
- the first aperture being arranged to receive an exterior airflow, the second aperture being arranged to receive a first interior airflow, the third aperture being arranged to receive a second interior airflow, the outlet aperture being arranged to evacuate air outside of the case;
- a first door rotatably attached to the case, the first door being movable between an open position where the first aperture is open, a closed position where the first aperture is closed, and a partially-open position where the first aperture is partially open;
- a second door, rotatably attached to the case, the second door being movable between an open position where the second aperture is open and a closed position where the second aperture is closed;
- and
- a third door rotatably attached to the case, the third door being movable between an open position where the third aperture is open, a closed position where the third aperture is closed;
- wherein the first door is arranged to partially allow the exterior airflow in its closed position;
- and
- wherein the case defines a fourth aperture arranged between the first aperture and the outlet aperture, with the third door being configured to assume a position in which it seals the fourth aperture so that the exterior airflow is prevented from reaching the outlet aperture.
