To avoid frost development inside our fridge, the industry adopted frost-free technologies that reduce the moisture inside, thereby preventing the condensate to freeze. The idea is to push cold air from the evaporator that passes through an actuator where the air deviates into the freezer or the shelves we store our daily supplies in.
The challenge is to, instead, deflect this common airflow into six different shelves. Meaning, a dedicated airflow for each shelf!
