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:a primary air flow passage coupled to receive a flow of primary air form a single primary air source; a bypass flow passage fluidly coupled in parallel with the primary air flow passage; a first heat exchanger having at least a first fluid flow path and a second fluid flow path, the first fluid flow path fluidly coupled in series in the primary air flow passage, the second fluid flow path coupled to receive a flow of compressed air from the compressed air source, the first heat exchanger adapted to transfer heat between the primary air and the compressed air and supply at least conditioned compressed air; and a bypass valve mounted on the bypass flow passage and selectively moveable between a closed and an open position to control primary air flow rate through the bypass flow passage, whereby primary air flow rate through the first heat exchanger is controlled to thereby control conditioned compressed air temperature.
