SUB FREEZING LOAD HEAT EXCHANGER BYPASS

摘要

An air-liquid heat exchanger assembly for an environmental control system of an aircraft is provided including a heat exchanger configured to transfer heat between air and a liquid. The heat exchanger includes a first chamber and a second chamber arranged generally in series relative to a flow of the liquid. A movable bypass valve is operably coupled to a controller. The bypass valve is positioned between and coupled to the first chamber and the second chamber. The bypass valve is configured to control the flow of the liquid through the second chamber and a bypass conduit in response to measured operating conditions of the assembly.
