General information about heating and ventilation (Focus Turnier 1)

Part of the oncoming air flow enters the cabin through the ventilation grille in front of the windshield. On its way into the cabin, fresh air passes through dust filters and a four-stage air blower. And if you are hit in the nose by the smell of perfume from the person sitting in front or unpleasant industrial exhaust gases, you can quickly create your own climate in the Focus using the air circulation button. This does not work for long, because otherwise, especially in autumn and winter, you will "stewing in your own juice". As soon as the windows fog up, you need fresh air to flow to them again. The air distribution regulator in the Focus will do this automatically for you - it will switch back to fresh air. You will achieve the same effect if you turn on the ignition again after a short break in movement. To maintain the transparency of the glass, the air flow (forced ventilation) slides along the glass while driving.

Forced ventilation ensures a constant exchange of air even with closed nozzles and windows. Depending on the position of the flap directing the air flow, a different climate is created in the cabin using the distributor nozzles.





To do this, fresh air passes through the aluminum plates of the heating heat exchanger and mixes with cold air to the desired temperature level. Without an air blower, ventilation functions depending on the speed, so when driving short distances and in city traffic, the blower always "works" at stage 1 or 2. Advantage: regardless of the speed, the air flow is distributed faster in the cabin. The air blower is located in front of the heat exchanger and therefore does not cool the cabin even on cold days.
