With the spike in Corona Virus cases being recorded almost daily, we at Rayneau's Automotive Department thought it fit to
share this information about using your airCon during this unprecented pandemic
When to Use Your AirCon “Re-circulation” and “Fresh Air Mode”
Buttons?
There are two buttons on a car’s air conditioner. One is the “recirculation” button, and the other is the “fresh air mode” button.
How to use these buttons is one of the things commonly reported
as unknown by vehicle owners, so here we will tell you about their distinctions.
What is “recirculation mode”?
Recirculation is used is to circulate the air
inside the car.Selecting this button closes an air duct in the front of the car
so that the air from outside the car does not enter the car.
What is “fresh air mode”?
Selecting this button introduces outside air into the car by
opening an air duct in the front of the vehicle.
Which to use, recirculation or fresh air mode? When it is
better to use recirculation mode.
It is better to use re-circulation in the
following cases.
You want to make the air conditioner work quickly
Compared to fresh air mode, using the air conditioner in
re-circulation mode improves efficiency and the air conditioner works more
quickly.
This is the same using air conditioners in the
room of a building with the doors and windows closed.
If you do not close the room, the air from the air conditioner will escape, it will not get cold or warm up easily.

Also, air conditioning will be stronger in re-circulation mode
than fresh air mode.
You do not want dirty air or unpleasant odours inside the car
When driving in a tunnel, or behind a large truck etc. with the
windows of the car open, dirty air and exhaust gas comes in. This is very
unpleasant.
In these scenarios, it is best switch to re-circulation mode, to block the entry of unclean outside air.

When it is better to use fresh air mode
To defog the windscreen quickly
Foggy windscreens are due to the temperature difference between
the inside and the outside of the vehicle.
It is necessary to eliminate this temperature difference in
order to defog the window.
In fresh air mode, it is possible to
eliminate the temperature difference between the inside and the outside of the
vehicle, so that the window can be defogged.
In this case, choose the windscreen defroster in fresh air mode, so that
outside air blows out around the window.
If you want to get defog as soon as the front window becomes
cloudy, using the air conditioner at the same time will be faster.
You want to ventilate the vehicle
When you smoke a cigarette or eat food in the car, it can become
full of unpleasant odours.
In such a case, switch to fresh air mode to ventilate the car by bringing in fresh air from outside.

What is the manufacturer's recommendation?
When looking at instruction manuals and explanations on the
websites of automobile manufacturers, most say that fresh air mode should be
the default for normal use.
The reason for this is that not only the windows become foggy if
left in re-circulation mode for a long time, the air inside the car also
becomes unclean and short of oxygen, which can result in sleepiness.
For this reason, it is
best to use "fresh air mode" usually and to select
"re-circulation mode" only when it is better to recycle the inside
air.
