A temperature sensor arrangement () includes a sensor cavity (), a temperature sensing element () being positioned along a center line () of the sensor cavity () and generating a signal indicating temperature of air flowing thereto, and a generally cylindrical outer casing () surrounding the sensor cavity (). In one embodiment, the outer casing () includes a pattern of flow passages () for allowing air flow to the temperature sensing element () in the sensor cavity (), the flow passages () being angled such that there is no direct line of air flow from an exterior of the outer casing () to the sensing element (). In another embodiment, the flow passages () are arranged in an offset pattern relative to a center line () of the housing cavity (), such that there is no direct line of air flow from an exterior of the outer casing () to the sensing element ().

An air cycle environmental control system for high pressure water separation omits a condenser heat exchanger and includes a reheater capable of placing compressed air in a heat exchange process to condense water vapor. A first turbine is in direct flow communication with the reheater, while the first turbine is capable of condensing water vapor from the compressed air. A water extractor is in flow communication with the first turbine and the reheater, while a second turbine is downstream of the reheater. The second turbine is capable of cooling a reheated, dehumidified air from the reheater to produce a conditioned air for supply to an enclosure. A method of water separation from a high pressure water vapor bearing air omits a step of condensing water vapor in a condenser heat exchanger and includes the steps of cooling a compressed air in a reheater heat exchanger such that the compressed air becomes a cold air. Water vapor is then condensed from the cold air to become a dehumidified air. Thereafter, a step of absorbing a heat of sensible cooling and condensation in the reheater occurs. Finally, a reheated air from the reheater undergoes expansion by a second turbine for eventual supply to the enclosure.

Environmental control system no condenser high pressure water separation

An environmental control system includes a single heat exchanger, a single water separator and two air cycle machines on separate spools. Cooling turbines of the air cycle machines are cascaded. Air flows through both air cycle machines during normal operation of the environmental control system. If one of the air cycle machines fails, air can be bypassed around the failed air cycle machine. Cascading allows water separation to be performed by a mid-pressure water separator located between the air cycle machines.
