Performance of Thermoelectrics and Heat Pipes Refrigerator

Most of refrigerators commonly use the conventional refrigeration system known as Vapor Compression Refrigeration System becoming a big issue lately due to ozone depleting substance it uses as the refrigerant. This paper will shows step by step of an experiment with the objective of constructing a refrigeration system based on thermoelectric which is reliable and compete able with the Vapor Compression Refrigeration System. The designing of this refrigeration system shows attention to the environment that is combined with the knowledge so the environmental friendly technology can be applied. The performance of thermoelectric refrigerator was conducted under variation of input power (40W, 72W, and 120W) and operated in ambient temperature and cooling load of water 1000mL to investigate the characteristic of system, the performance, and also the COP. The COP is decrease by increasing of cooling load, QL. The best actual COP is 0.182 reached when the refrigerator operated at input power 40W. The result, it shows that decreasing of ambient temperature affects the decreasing of cabin temperature. Thermoelectric and heat pipe refrigerator cooling system can reach cabin temperature with power 120Watt (8.73A, 14V) produces temperature of compartment is 10.63°C indicates effective performance work-based thermoelectric applications.
