Abstract : A detailed engineering design is presented for a 24,000 Btu/hr Thermoelectric Environmental Control Unit. System design is based on an optimization analysis performed on an analog computer. Procedures followed and results obtained are described. Twelve design parameters were optimized for minimum weight and maximum efficiency. System is 28 in. wide x 18 in. deep x 63 in. high, weighs 380 lbs. and operates at an over-all C.O.P. (including fans) of 1.12 with a net cooling capacity of 24,000 Btu/hr at design operating conditions. Dual frequency (60 and 400 cps) fans are used. Power rectifier furnishes 3 phase, full wave d-c power without voltage transformation. Modulated capacity control is provided from full cooling to full heating as required by system load. The design is based on air-to-air heat exchange utilizing aluminum heat transfer surface. Operating instructions, maintenance procedures, manufacturing procedures and cost analysis information are included. Recommendation is made to develop a prototype unit.
