Abstract
An integrated environmental control system for providing conditioned air supply in an aircraft is provided. The system includes an integrated bootstrap air cycle subsystem and a regenerative air cycle subsystem, which are in heat exchange relationship. The bootstrap and the regenerative air cycle systems are also in heat exchange relationship with a liquid cooling cycle subsystem. In the bootstrap cycle, bleed air is compressed and expanded. After absorbing heat from the liquid cycle, the expanded air from the bootstrap cycle is received and expanded by a first turbine of the regenerative air cycle. Before it is received by a compressor of the regenerative cycle, the air flow, which is expanded and cooled by the first turbine, absorbs heat from the liquid cycle, supplies air to the cabin and absorbs heat from the bootstrap cycle. After the compression, the air flow is received by a second turbine of the regenerative cycle and expanded. The expanded air flow merges into the air flow from the first turbine of the regenerative cycle.
