Abstract:

This report describes a detailed engineering design of a thermoelectric environmental control unit ECU. The ECU is a complete self- supporting unit that requires only a 115 vac, 3 phase, 60 or 400 cycle electrical power input. Besides the thermoelectric heat exchanger, the ECU has an ac to dc power converter, a 60 to 400 cycle frequency inverter, a thermal control system, a malfunction detection and protection system, 3 fans and a master control panel that can be removed for remote operation. At design point, the ECU has a cooling capacity of two refrigeration tons 24,000 Btuhr. A requirement was to design a unit with an overall operational system coefficient of performance COP of one or greater at design point. The report describes an ECU with a system COP of 1.10. The ECU is an air to air unit designed for ground operation.
