摘要： An environmental control system for conditioning air in a vehicle compartment, such as an aircraft cabin. Cool expanded higher-pressure air from a turbine is mixed with recirculated warmer, lower pressure air from the compartment. The air is mixed and recirculated by a jet pump which includes an inlet section, an outlet section, a diffuser section and a mixing section. The mixing section includes a plurality of separate mixing chambers. The diffuser section includes diffusers for receiving mixed gases from each of the mixing chambers. The outlet section receives the mixed gases which are then conveyed to the compartment. The inlet section includes for each of the mixing chambers, a primary nozzle for introducing the higher-pressure air into a respective mixing chamber, and a secondary nozzle for introducing the lower pressure air to a respective mixing chamber.

摘要： An environmental control system has a cooling loop including a cooling turbine which, in use, drives a compressor, and an intercooler apparatus, for cooling air compressed by the compressor prior to the air being expanded and cooled over the cooling turbine, and a heat exchanger to which at least a proportion of the cooled and expanded air from the turbine is fed to cool a heat load, and wherein, in a first mode of operation, the cooling loop is closed so that the air circulates around the closed loop from the compressor to the intercooler apparatus to the cooling turbine, and thence to the heat exchanger, and back to the compressor, and in a second mode of operation the cooling loop is open to allow working fluid to pass from the system whilst further working fluid is introduced into the cooling loop, and wherein an ambient air inlet valve is provided to provide for the admission of ambient air to the cooling loop, when the system is operating in the second mode of operation.
