Abstract

A system for feeding pre-cooled air to an aircraft environmental control system (ECS) (28) comprises an aircraft engine (16) including a compressor section (20) having a bleed port, and an engine oil circuit including an oil cooler (25) for cooling engine oil. The system further includes an air pre-cooler (34) including an air passage (38) in heat exchange relationship with a coolant passage (36). The air passage (38) has an air inlet (38a) fluidly connected to the bleed port of the compressor section (20) and an air outlet (38b) fluidly connected to an inlet (32) of the ECS (28). The coolant passage (36) has a coolant inlet (36a) fluidly connected to an oil outlet of the oil cooler (25) and a coolant outlet (36b) fluidly connected to the engine oil circuit at a location upstream of the oil cooler (25).
