Abstract
An airflow door for a heating, ventilation, and air conditioning (HVAC) system. The airflow door has a first material and a second material. The first material and the second material are temperature responsive materials that change shape at different temperatures such that at a first temperature the first material and the second material are shaped to provide the airflow door with a first configuration, and at a second temperature the first material and the second material are shaped to provide the airflow door with a second configuration that is different from the first configuration.
Claims8
A heating, ventilation, and air conditioning (HVAC) system comprising:
- a case defining an inlet, a face outlet, and a foot outlet;
- an evaporator and a heater core within the case;
- an air mix door movable to control airflow through the heater core;
- a first air mode door including a first material and a second material that have different rates of thermal expansion to provide the first air mode door with different configurations at different temperatures, the first material and the second material are connected to a first support that is mounted within the case at the face outlet;
- a second air mode door including a third material and a fourth material that have different rates of thermal expansion to provide the second air mode door with different configurations at different temperatures, the third material and the fourth material are connected to a second support that is mounted within the case at the foot outlet.
