Blower Fan HVAC, temperature mixing flap

"Blower Fan" new HVAC temperature mixing damper also adopted a new mechanism. Temperature of the mixed damper is gate-like member evaporator and heater core between. Before and after shortening the length of the sliding door: single door from the temperature of the mixed damper replaced by a sliding door. Successfully reduced the space occupied by the throttle section. The length of the front and rear portions of the damper is more significantly reduced from 110mm to 40mm. Generally, HVAC damper is the use of switch-mode (single door), by changing the angle of the throttle switch, and adjust the amount of cold and warm air to control the temperature. For example, when the damper closed to the lowest position, the heater is completely blocked (sealed), supply only cold air outlet, and with the throttle open up gradually, more and more the amount of warm air, air temperature will rise. After the throttle to the highest position, the outlet will supply only warm air. Because it requires interrupting performance, so the sealing material excellent in rubber and urethane.
