A heat exchanger includes a plate with an external surface, a channel, and a nozzle. The external surface bounds an interior of the plate. The channel is disposed in the heat exchanger and passes through a portion of the interior. The nozzle is integrally disposed in the heat exchanger, extends through a portion of the external surface, and is fluidly connected to the channel. The nozzle is configured to transport a liquid from the channel, through the external surface, and to distribute the liquid onto a portion of the heat exchanger.

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.

A compact lightweight air filtration system is disclosed. The air filtration system includes a hydrophobic particulate/coalescing filter and a cleanable ozone converter housed in a housing with an inlet and an outlet. Air flowing from the inlet to the outlet passes through the particulate/coalescing filter element and then the cleanable ozone converter to remove particulates, aerosols, liquids, and ozone.

An isolation section assembly includes a section housing defining an interior space. The section housing includes a door with access to the interior space. The isolation section assembly includes an enclosure abutting the door. The airlock enclosure defines an interior airlock space. The interior airlock space is configured and adapted to be at a negative pressure relative to a cabin area. An air recirculation system in fluid communication with at least one of the interior space of the section housing or the interior airlock space.

An ozone converter includes a toroidal shaped inlet housing and an outlet housing that is removably coupled to the inlet housing. The converter also includes a ring shaped ozone removable core disposed at least partially within the inlet housing.

An environmental control system (ECS) includes an air conditioning pack that receives outside air; a regenerative treatment subsystem, wherein the treatment subsystem includes a treatment bed configured to cycle between an adsorption phase and a desorption phase; and a fan that receives recirculated air from the environment and moves the recirculated air to a mixing manifold.

An environmental control system of an aircraft includes a ram air circuit including a ram air shell having at least one heat exchanger positioned therein. A dehumidification system is arranged in fluid communication with the ram air circuit and at least one compressing device is arranged in fluid communication with the ram air circuit and the dehumidification system. The at least one compressing device includes a turbine and a compressor operably coupled via a shaft. A fan is operably coupled to the ram air circuit. At least one compressing device is arranged non-linearly with the ram air circuit such that an axis of rotation of the fan is offset from the axis of the shaft.

A flow sensing ozone converter includes an inlet housing, an outlet housing, and a central housing. The inlet housing defines a first pressure port. The outlet housing defines a second pressure port. The central housing extends between a second end of the inlet housing and a first end of the outlet housing.
