A method of providing gas to a system which separates from a pressurized supply gas, product gas, includes conditioning the supply gas by both cooling and drying the supply gas.

Oxygen supply system

An air conditioning system for an aircraft in which cabin air is recirculated and mixed with cold air from an air conditioning machine which includes at least an expansion turbine over which warm pressurised air is expanded and cooled, and wherein the system includes a heat exchanger in which a heat load from hot cabin air and/or a hot avionics system is exchanged with the warm pressurised air prior to the pressurised air being expanded by the expansion turbine.

Air conditioning system

A temperature sensitive valve () includes a body () affording a passageway () for fluid, a valve member () which is moveable relative to the body () between first and second positions to control the flow of fluid through the passageway (), a retaining member () movable with the valve member () and being engageable with a holding device () to retain the valve member () in the first position whilst the temperature is below a threshold value, and there being a release actuator () movable when the temperature is at the threshold value to disengage the retaining member () and holding device (), to permit the valve member () to move from the first to the second position.

Valves

An air conditioning system for conditioning a supply of hot pressurised air for use in an environment the system including a primary heat exchanger in which heat in the hot pressurised air supply is exchanged with a cooling fluid, a compressor to compress the supply of pressurised air cooled in the primary heat exchanger, a secondary heat exchanger in which heat in the compressed air supply is exchanged with a cooling fluid, and an expansion device for expanding and cooling the compressed air supply cooled in the secondary heat exchanger, mixing apparatus for mixing the expanded and cold supply air with recirculating air from the environment, a by-pass flow path for compressed cooled supply air from the secondary heat exchanger to the environment, and a secondary supply flow path for the hot pressurised air to the secondary heat exchanger, a first valve in a primary supply flow path to the primary heat exchanger, a second valve in the secondary supply flow path to the secondary heat exchanger, a third valve in a flow path for the compressed air supply to the secondary heat exchanger, a fourth valve in the flow path for cooled compressed supply air from the secondary heat exchanger, and a by-pass valve in the by-pass flow path for compressed cooled supply air from the secondary heat exchanger, a first air flow sensor for sensing air flow from the supply to the primary heat exchanger when the first valve is open, a second air flow sensor for sensing air flow from the secondary heat exchanger along the by-pass flow path when the by-pass valve is open, and a third air flow sensor for sensing air flow of the expanded and cold supply air towards the mixing apparatus, and a controller for controlling each of the valves and for receiving inputs from each of the air flow sensors.

Air conditioning system and method of testing

An air conditioning system for an aircraft in which cabin air is recirculated and mixed with cold air from an air conditioning machine which includes at least one expansion turbine over which warm pressurized air is expanded and cooled, and wherein the system includes a heat exchanger in which a heat load from hot cabin air is exchanged with the warm pressurized air prior to the pressurized air being expanded by the expansion turbine, further including a condenser heat exchanger in which recirculating cabin air is used to cool and promote water removal from the warm pressurized air before it is expanded by the expansion turbine.
