Space environmental control systems must control cabin temperature and humidity. This can be achieved by transferring the heat load to a circulating coolant, condensing the humidity, and separating the condensate from the air stream. In addition, environmental control systems may be required to remove particulate matter from the air stream. An assembly comprised of a filter, a condensing heat exchanger, a thermal control valve, and a liquid carryover sensor, is used to achieve all these requirements.A condensing heat exchanger and filter assembly (CHXFA) is being developed and manufactured by SECAN/AlliedSignal under a contract from Dornier Daimler-Benz as part of a European Space Agency program. The CHXFA is part of the environmental control system of the Columbus Orbital Facility (COF), the European laboratory module of the International Space Station (ISS).The CHXFA contains a filter to remove particulates from the air stream, and a differential pressure sensor to monitor filter pressure drop. The condensing heat exchanger reduces the air temperature and the humidity level. Efficient air-water separation is achieved by a combination of a hydrophilic coating on the heat exchanger air flow passages and a water removal section. A thermal control valve regulates the temperature of the outlet air. A sensor is incorporated in the outlet line to detect liquid carryover in the air stream.This paper gives an overview of the condensing heat exchanger assembly developed for the Columbus Orbital Facility.
