What is the function of the blower in the aircraft's air conditioning system?

The function of the blower in the aircraft's air conditioning system is primarily to circulate air through the evaporator coils. This process is essential for maintaining the desired temperature within the aircraft cabin. The blower draws ambient or conditioned air from the cabin and forces it over the evaporator coils, where it is cooled before being redistributed into the cabin. By effectively moving air, the blower helps to ensure a steady flow of cooled air, providing comfort to passengers and crew.

Understanding the role of the blower highlights its importance in the overall air conditioning process. The movement of air over the evaporator coils is what allows the heat exchange to occur, ultimately cooling the air that is supplied back into the cabin. This function is crucial in maintaining appropriate cabin temperatures during flight.
