Abstract: Embodiments relate to heat exchanger contamination monitoring in an air conditioning system. An aspect includes receiving, by a contamination monitoring logic from a primary heat exchanger outlet temperature sensor, a first temperature comprising an air temperature at an outlet of a primary heat exchanger. Another aspect includes receiving, from a secondary heat exchanger outlet temperature sensor, a second temperature comprising an air temperature at an outlet of a secondary heat exchanger. Another aspect includes receiving, from a compressor outlet temperature sensor, a third temperature comprising an air temperature at an outlet of a compressor. Another aspect includes determining, based on the first, second, and third temperature, a heat exchanger contamination value. Another aspect includes comparing the heat exchanger contamination value to a predetermined contamination threshold. Another aspect includes based on the heat exchanger contamination value being greater than the predetermined contamination threshold, sending a maintenance warning.

Abstract: A method of monitoring a heat exchanger arrangement is provided. The method includes detecting a rotational speed of a ram air fan configured to draw air through the heat exchanger arrangement. The method also includes detecting a power input from a motor to the ram air fan to maintain a commanded rotational speed of the ram air fan. The method further includes comparing the power input detected to a predetermined power limit for the commanded rotational speed. The method yet further includes decreasing the rotational speed of the ram air fan with a controller if the power input detected exceeds the predetermined power limit.

Abstract: An Environmental Control System (ECS) for an aircraft includes a ram air system having a ram inlet and a ram outlet. The ECS includes a cabin air compressor motor, a diverter valve, and a dedicated outlet. The cabin air compressor motor has a motor inlet passage and a motor outlet passage with the motor inlet passage being coupled to the ram inlet. The diverter valve includes a first diverter inlet, a first diverter outlet, and a second diverter outlet. The first diverter inlet is coupled to the motor outlet passage. The dedicated outlet is connected to the first diverter outlet in a flight mode of operation of the aircraft and the ram outlet is connected to the second diverter outlet in a ground mode of operation of the aircraft.

Abstract: A method of operating a RAM inlet header (RIH) is provided. The method includes determining a temperature of RAM air flows in a body through which RAM air flows from an inlet toward a heat exchanger, determining a temperature of excess air for use in an environmental control system (ECS) and, in an event the temperature of the excess air is less than the temperature of the RAM air flows, directing a curtain of the excess air from a nozzle body and along a wall of the body into flows of the RAM air and toward the heat exchanger.

Abstract: A method and apparatus for operating an air cycle machine is disclosed. The apparatus includes a detector for measuring a rotational speed of a component of the air cycle machine. A processor estimates a rate of change of rotational speed of the component from the measured rotational speed and shuts down the air cycle machine when the estimated rate of change of the rotational speed of the component is greater than a selected rate threshold.
