Abstract:
A temperature-controlled air supply system for use with a compressed air source and for connection to an aircraft on the ground, the air supply system comprising:an air amplifier having at least a cooling air inlet port, a cooling air outlet port, an interior passageway therebetween, and a control air inlet port leading to the passageway; a first heat exchanger assembly adapted to receive a flow of compressed air from the compressed air source and a flow of cooling air and to transfer heat from the compressed air to the cooling air and supply cooled compressed air; a pressure control passage having an inlet and an outlet, the inlet configured to receive compressed air flow from the compressed air source and the outlet in fluid communication with the air amplifier control port; and a first valve mounted on the control pressure passage and selectively moveable to control compressed air flow rate and pressure to the air amplifier control air inlet port.
