Window air conditioning units are designed to have the back half, which contains the condenser and compressor, placed outside the window. There are a few reasons for this placement:
Heat dissipation: The condenser and compressor components of an air conditioner generate heat during the cooling process. Placing them outside allows for better heat dissipation into the outdoor environment. The outdoor placement helps prevent the buildup of heat inside the room, allowing the air conditioner to cool more efficiently.
Air circulation: Placing the back half of the unit outside enables proper air circulation around the condenser coils. Adequate airflow is crucial for the efficient operation of the air conditioner. When the unit is placed outside, it can draw in fresh air from the outside, cool the condenser coils effectively, and expel the hot air generated during the cooling process.
Noise reduction: Air conditioning units can produce some noise during operation, primarily from the compressor. Placing the noisier components of the unit outside helps reduce indoor noise levels, providing a more comfortable environment within the room.
Space utilization: Window air conditioners are designed for installation in windows, and their design allows for easy integration into the window frame. Placing the back half of the unit outside utilizes the available window space effectively without taking up valuable indoor floor space.
It's worth noting that other types of air conditioning systems, such as split air conditioners or central air conditioning systems, also have their condenser units placed outside the building. This outdoor placement is common for various air conditioning configurations due to the reasons mentioned above, including heat dissipation, airflow, noise reduction, and space utilization.
