Abstract : This research examines current thermoelectric cooling (TEC) systems for possible microclimate cooling applications. TEC systems offer simplicity, but have some drawbacks. Although TEC systems have few moving parts, the power required for operation and the weight of the systems limit their usefulness in dismounted, untethered modes of operation. Unlike phase change material (PCM) cooling system TEC's can provide uninterrupted cooling for extended periods of time. TEC's operate on electricity and so do not suffer from the logistical difficulties of resupplying frozen PCM's to the field. In comparison to vapor compression (VC) cooling systems, TEC's are heavier and significantly less energy efficient. For tethered modes, with a large source of power, the simple TEC systems of fer a great deal. TEC's lose their advantage if power is limited and/or the complete system, including the power source, must be carried by an individuals. (MM)
