Abstract:

The present state of the air-conditioning art is reviewed as applied to the cooling of Air Force mobile ground-based electronic equipment. Basic cooling processes are summarized and e aluated for possible application to refrigeration cycles. Recommended cooling processes are applied to thermodynamic-cycle analyses and compared on the basis of power requirements and probable equipment size and weight. Thermodynamic analyses cover mechanical, electrical, and heat-motivated refrigeration cycles and devices. Advisabi ity of employing waste heat from a reciprocating internal-combustion engine to power a cooling system is investigated and found insufficient. It is concluded that present air-conditioning systems, based on the vapor-compression refrigeration cycle, are the most practical and efficient means for the cooling of ground-based electronic equipment. Regenerative Stirlingcycle equipment has the inherent thermodynamic ability to exceed efficiency of vapor-compression cycles, but is presently inferior due to technological limitations. Continued refinement of vapor-compression equipment in areas of compressors, heat exchangers, and air-moving equipment is recommended. Author
