HVAC TEMPERATURE CONTROL BYPASS THROTTLE

摘要

The present teachings provide for an HVAC assembly. A first flue can be configured to fluidly couple a first heat exchanger to a mixing flue. A second flue can be configured to fluidly couple a second heat exchanger to the mixing flue. A door can inhibit fluid communication through the second flue when in a first position. The door can inhibit fluid communication through the first flue when in a second position. The door can permit fluid communication through the first and second flues when in a third position. The third flue can be configured to fluidly couple the first heat exchanger to a portion of the second flue downstream of the second heat exchanger and upstream of the mixing flue when the door is in the third position.

主权项

1. A vehicle heating, ventilation, and air conditioning (“HVAC”) assembly comprising:
a mixing flue; a first flue configured to fluidly couple a first heat exchanger to the mixing flue; a second flue configured to fluidly couple a second heat exchanger to the mixing flue; a first door configured to move between a first, a second, and a third position, the first door inhibiting fluid communication through the second flue when the first door is in the first position, the first door inhibiting fluid communication through the first flue when the first door is in the second position, the first door permitting fluid communication through the first and second flues when the first door is in the third position; and a third flue configured to fluidly couple the first heat exchanger to a portion of the second flue downstream of the second heat exchanger and upstream of the mixing flue when the first door is in the third position.
