Which side of the fan blows out the airflow? Could it reverse the airflow?

Which side of the fan blows out the airflow? Could it reverse the airflow?

The common RV fridge has two ventilation side vents, upper and bottom. The correct mounted way is that bottom RV side vent mounts the fan to push fresh air in, and RV upper side vent near the top mounts the fan to exhaust the heat out. The way of installation complies with the air circulation rules: hot air rises and cold air sinks. It is the key to quickly boost the air circulation of the RV fridge. You are based on to the need to mount them.

RV refrigerator side vents
How does RV fridge works?
The general RV fridge work called absorption refrigerator. The absorption refrigerator uses a chemical reaction with ammonia and hydrogen gas induced with heat and with evaporation and condensation. The RV fridge works by using the heat to send the fluids (ammonia, hydrogen gas) through various tubes and it has zero moving parts only using gravity to pull chemical down. The evaporation and condensation it comes down through these tubes and it creates the cool inside the fridge or rather absorbs the heat out of the fridge.
Mounted the fan grille side outwards to exhaust out the heat on the upper side of RV side fridge vent.
It is impossible to create the different airflow (both air out and air in) simultaneously in the same RV fridge place. The common mounted way is place two fans to boost the circulation of RV cooling system. One is on the upper vent, and another one is the bottom vent. If you want to exhaust out the air, the installation way needs to mount the fan grille side outwards and on the upper fridge side near the top.
Mounted the fan grille side inwards to pull the air in on the bottom side of RV side fridge vent.
Consider a fridge fan to circulate more air inside the fridge if you’re using an absorption fridge. This helps keep a more consistent temperature and can help maintain more even cooling. If you want to pull fresh air in, you need to mount the fan grille side inwards and on the bottom fridge side.
