The installation of an air conditioner in a room depends on the type of air conditioner being used (window AC or split AC) and the room's layout. Let's consider the two common types of air conditioners:
Window Air Conditioner: This type of AC is installed in a window or a hole in a wall. In this case, the front of the air conditioner (where the vents and controls are located) should face the interior of the room. The backside, containing the condenser and compressor, should be facing the exterior of the building. This setup allows the AC to expel hot air generated during the cooling process outside the room.
Split Air Conditioner: A split AC consists of two units: an indoor unit and an outdoor unit. The indoor unit, which includes the cooling coil and blower, is mounted on the room's wall or ceiling. The outdoor unit, containing the compressor and condenser, is placed outside the building. In this case, the front of the indoor unit should face into the room, while the backside should be towards the wall or ceiling.
The reason for positioning the front side of the air conditioner towards the interior of the room is to ensure efficient cooling. The cool air is blown into the room from the front, allowing it to circulate effectively and cool the indoor space. Conversely, the backside of the AC contains the components that release heat, and it needs to be exposed to the outside or a well-ventilated area, so the heat doesn't get trapped inside the room.
Proper installation of the air conditioner ensures that the cooling process is efficient, and it helps maintain a comfortable and pleasant indoor environment. Additionally, positioning the AC as recommended also ensures that the unit functions optimally and minimizes the risk of heat buildup or damage to the system.
