Abstract
A heat exchanger subsystem for an environmental control system comprises a heat exchanger array having a plurality of heat exchanger elements that operate in parallel to an inlet cooling airflow to the heat exchanger array such that each load heat exchanger is connected to a separate load with each heat transfer loop operating in substantially independent fashion without load interaction effects. In addition, continuous ice and water removal is provided allowing continuous subfreezing operation improving cooling performance along with anti-ice provisions which recover rejected heat for improved energy efficiency. The heat exchanger elements may include air-to-air heat exchanger cores, liquid-to-air heat exchanger cores, and hot bars internal or external to the heat exchanger cores.
