Preliminary investigation of performance and temperature distribution of thermoelectric cooler box with and without internal fan (original) (raw)

Thermoelectric cooler is one type of refrigeration system that is environmentally friendly because it does not use refrigerants which have potential damaging the ozone layer. In this study, an experimental performance of thermoelectric refrigerator using fan and without fan is presented. The result shows that the cold side temperature decreases from 25.5 degree C to-5 degree C for 37 watt (with fan) and 25.5 degree C to-7.5 degree C for 37-watt without fan. Using 43-watt power supply, the cold side decreases from 25 degree C to-5 degree C for fan usage, and from 26 degree C to-7.5 degree C in 60 minute and 75 minutes, respectively. Using fan for cold sink inside the cabin will distribute the cabin temperature of cool box evenly and also increase the capability of heat transfer performance of cooler box of thermoelectric. Maximum average COP is 0.103 and achieved by 37-watt power supply with cold sink fan.
