Title:
COMPRESSED AIR SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/091276
Kind Code:
A1
Abstract:
A compressed air supply system according to one aspect of the present application bleeds compressed air from a gas turbine engine and supplies the bled compressed air to an air conditioning pack of a machine body, said compressed air supply system comprising: a low pressure air bleed port through which compressed air is to be bled from upstream of a high pressure compressor; a high pressure air bleed port through which compressed air is to be bled from downstream of the front part of the high pressure compressor; a main pipe which extends from the low pressure air bleed port toward the air conditioning pack; an auxiliary compressor which is provided to the main pipe and which raises the pressure of compressed air; a high pressure air bleed pipe which connects the main pipe with the high pressure air bleed port; a high pressure air bleed valve which is provided to the high pressure air bleed pipe; and a control device which opens the high pressure air bleed valve when it is determined that the high pressure air bleed valve remaining closed would result in a pressure deficiency state where the outlet pressure of the main pipe cannot be maintained in the pressure range required by the air conditioning pack.
