Title : Fluid Analysis For Mini Fan Refrigerator Using Thermoelectric Cooler
The cooling is one of the processes can be used for various types of applications, starting from maintaining food industry products and medical products such as drugs and vaccines. The cooling process now still uses compression-based preservation technology using cooling gas. The types of cooling gas used are R134a and R600a. However, the R134a contains HF which has been banned for used, and the R600a contains HF gas which can reduce the ozone layer. In addition, a single fan compressor system that uses cooling gas in a steam compressor has difficulties in regulating the temperature of the target compartment. Based on this, an alternative cooling technology is needed. Thermoelectric cooler (TEC) is an alternative cooling technology, because TEC has advantages such as small size, lower noise and vibration, easier in temperature regulation, low maintenance requirements, can absorb heat using the principle of heat difference so that in addition to being able to the cooler can also be a heater, and besides that it can be turned on with a DC current. Obtained a solution in the form of cooling using a thermoelectric cooler, using a fan in the refrigerator.The current research examines the application of CFD (Computational Fluid Dynamic) to analyze the flow of wind into the refrigerator. Use the existing CFD analyst application. To analyze the flow of fluid entering the refrigerator, it is simplified for this refrigerator, by cutting the inside of the refrigerator. So that the incoming fluid flow can be reviewed, from the incoming air velocity can be analyzed with a simple correlation to the wind speed generated with existing pwm. It is expected that from this research, researchers can find out the wind phenomenon that is in the refrigerator so that it can be used for further research.
