Multi-zone temperature control in air cycle refrigeration systems

摘要

An air cycle refrigeration system (10) pressurizes and cools flight compartment (115) and cabin (120) by the provision of chilled air thereto. Trim valves (180) and (205) set by a common actuator (195) control the mixture of uncooled system inlet air with the chilled air for individual regulation of the temperatures of the cabin and flight compartment.
