摘要： The present disclosure provides a preconditioned air (PCA) unit for supplying preconditioned air to an aircraft (1) parked on the ground. The PCA unit comprises an air duct (7) with an air inlet and an air outlet connectable to a hose (5) for conveying preconditioned air towards the aircraft. The PCA unit also comprises an air conditioning module (12a-c) removably mountable so that at least a part of the air conditioning module is positioned in the air duct between the air inlet and the air outlet. The air conditioning module comprises a heater unit (19) operable to heat air as it passes through the air duct.
