Integrated environmental control system for a helicopter

An integrated environmental control system for a helicopter having left, right, and mid mission equipment package bays containing electronic modules, the helicopter having a cockpit that includes electronic modules, comprising:

• an air cycle machine that includes a compressor stage and a turbine stage, said compressor stage being operative to provide a highly compressed airflow;
• means for providing a purge airflow;
• a regenerative heat exchange apparatus operative to transfer thermal energy from said highly compressed airflow to said purge airflow;
• a pressure swing adsorber nuclear/biological/chemical filtration apparatus that includes a high efficiency particulate air filter and first and second alternatively operative regenerative beds operative in combination to decontaminate and demoisturize said highly compressed airflow to provide a super-dry, decontaminated airflow, said second and first beds being alternatively purged of contaminants by said purge airflow;
• said turbine stage of said air cycle machine being operative to super cool said super-dry, decontaminated airflow to provide a super-cooled, super-dry, decontaminated airflow;
• and
• an airflow distribution network operative to channel said super-cooled, super-dry, decontaminated airflow, in seriatim, to the left and right mission equipment package bays and the cockpit for direct cooling of the electronic modules thereof and crew comfort,
• said airflow distribution network including
• a first distribution duct for channeling said super-cooled, super-dry, decontaminated airflow to the left and right mission equipment package bays,
• upstream parallel distribution ducts fluidically interconnected to said first distribution duct for directing said super-cooled, super-dry, decontaminated airflow through the left and right mission equipment package bays, respectively, for directly cooling the electronic modules thereof, and
• downstream parallel distribution ducts for receiving cooled, super-dry, decontaminated airflow discharged from the left and right mission equipment package bays, respectively, and
• a common distribution duct fluidically interconnected to said downstream parallel distribution ducts for channeling said cooled, super-dry, decontaminated airflow to the cockpit for cooling the electronic modules therein and for crew comfort.
