The concealed system in air conditioners and the most important advantages and disadvantages of concealed air conditioning
Concealed air conditioning system or Hidden air conditioner (In English: Concealed air conditioner) is a type of small central air conditioner that consists of two separate units, one outdoor and one indoor.
What distinguishes concealed air conditioners from other types of split air conditioners is that the indoor unit is hidden in the ceiling, hence the name "concealed.".
The concealed unit is placed inside the suspended ceiling inside the building in a hidden manner to maintain the aesthetic appearance of the place, and cold air is distributed here through a duct that is also installed in the ceiling.
Components of Concealed Air Conditioners
There are special components in each unit of the concealed air conditioner, whether indoor or outdoor, as follows:
External unit components
- Condenser + fan: TThe fan draws hot air from the room or area where the air conditioner is located, and this air is passed over the condenser to cool it. After cooling, the air is distributed inside the room from the other side of the fan.
- Compressor: The compressor reduces the volume of gas by compressing it.

The Freon liquid then turns into vapor, which is collected through a pipe in the device and transferred to the compressor in the outdoor unit to raise its temperature. This cycle, known as the cooling cycle, is repeated over and over again.
