Abstract

Solar cells are a powerful technology to convert solar energy into electrical energy directly, while thermoelectrics can convert electrical energy (potential difference) into heat energy (temperature difference). The combined solar cell and thermoelectric system is used as an air conditioner. The research was conducted by making a cooling system in the form of a cooling box with a cooling source on the roof side and wall side. The cooling source in this study is a thermoelectric cooling system consisting of a series of thermoelectric modules. The purpose of this study is to find that the position of the TEC affects the cooling results in the cooling box and determine the lowest temperature and performance of the cooling system in the cooling box. The method used is an experimental method with the model is a cooler box with cooler box dimensions: 520mm x 370mm x 440mm. Solar cells as electrical energy suppliers are placed in the presence of sunlight throughout the day and the output power from solar cells is distributed to the thermoelectric cooling system in series. so that thermal energy changes take place on its sides. The cold side of the thermoelectric will absorb heat from inside the cooling box, while the hot side of the thermoelectric will release heat to the environment outside the cooling box. The results showed that the positioning of the thermoelectric cooler on the roof side and the wall side of the cooler box affected the heat transfer and temperature achievement in the center of the cooler box. The average center room temperature achieved by the cooler on the roof side is 23.70 ℃ and 24.75 ℃ on the wall side. While the coefficient of performance of the cooling system in the cooler box with thermoelectric cooler on the roof side amounted to 2.17 and in the thermoelectric cooler on the wall side amounted to 1.8.

The research method used is experimental. The two modules are separately supplied with DC electrical energy so that heat is absorbed on the cold side and heat is released on the hot side so that a temperature difference occurs, and an aluminum heatsink is attached to the cold side and the hot side. The data obtained from the input data are ambient temperature, electric voltage, and electric current. Then what is obtained from the output data is the temperature of the hot side, the temperature of the cold side, and the temperature of the cold room. The results of the study on the TEC 1-12706 module with variations in electric voltage produce a minimum cold side temperature of 5.9°C with the highest CoP value of the cooling system of 0.1821, while variations in electric current produce a minimum cold side temperature of 8.0°C with the highest CoP value of the cooling system of 0.3247. For the TEG SP 1848 module, variations in electric voltage produce a minimum cold side temperature of 8.3°C with the highest CoP value of the cooling system of 0.2371, while variations in electric current produce a minimum cold side temperature of 11.1°C with a CoP value the highest cooling system is 0.2158. Thus this study achieved the result that the use of the TEC 1-12706 module with variations in electric voltage produced the lowest temperature of 5.9 oC. While the use of TEC 1-12706 with variations in electric current produces the highest CoP value of 0.3247. There for the TEC 1-12706 module has a higher performance than the TEG SP 1848 module in terms of the lowest temperature achievement and the highest CoP value.
