Bus air conditioning systems typically consist of a condenser, evaporator, compressor, and expansion valve. The condenser is usually mounted on the roof of the bus and is responsible for dissipating heat from the refrigerant. The evaporator is located inside the bus and is responsible for cooling the air inside. The compressor pumps refrigerant through the system, while the expansion valve regulates the flow of refrigerant to ensure proper cooling. In addition to these components, some systems may also include a receiver/dryer to remove moisture from the system and a blower motor to circulate air throughout the bus.
