Improved air cycle condenser cold inlet heating using internally finned hot bars

摘要

An environmental control system (ECS) includes an air cycle machine (10) with an expansion turbine (12-2) and a condenser (22) having a cold air inlet (22-1) connected to receive air from the expansion turbine (12-2). The condenser (22) has hollow, internally finned hot bars positioned at the cold air inlet (22-1) to prevent ice formation at the cold air inlet (22-1).
