Abstract

Temperatur kabin yang meningkat hingga 60°C akibat parkit di tempat terbuka dapat menimbulkan berbagai dampak merugikan, mulai dari kerusakan pada interior mobil hingga risiko kesehatan. Dalam upaya mengatasi masalah ini, penelitian telah dilakukan untuk mengembangkan sistem pendingin alternatif berbasis termoelektrik. Sistem pendingin berupa saluran udara dengan TEC 12706 yang divariasikan 6 dan 12 buah baik tanpa evaporative cooling maupun kombinasi evaporative cooling. Pengukuran temperatur dilakukan secara realtime menggunakan temperature data logger. Temperatur kabin yang diparkir tanpa sistem pendingin sebesar 46,3°C. Konfigurasi sistem pendingin termoelektrik ganda dan evaporative cooling 0,3 lpm menghasilkan perbedaan temperatur kabin dan lingkungan yang paling rendah yaitu 4,18°C dan menurun 9,54°C dibanding tanpa sistem pendingin. Penambahan sistem evaporative cooling dapat meningkatkan COP sistem pendingin. Dari hasil pengujian diperoleh COP tertinggi yaitu 1,07 pada konfigurasi sistem pendingin evaporative cooling 0,3 lpm (PE), namun Tkabin avg masih tinggi yaitu sebesar 44,34°C pada Tenv 38,13°C yang menghasilkan perbedaan temperatur dan lingkungan sebesar 6,17°C. Sedangkan pada konfigurasi pendingin termoelektrik dan evaporative cooling 0,3 lpm menghasilkan perbedaan temperatur kabin dan lingkungan sebesar 4,15°C, dengan Tkabin avg sebesar 36,73°C pada Tenv 32,58°C dengan COP 0,62. Cabin temperatures rising up to 60°C due to open-air parking can have a variety of adverse effects, ranging from damage to car interiors to health risks. In an effort to address this issue, research has been conducted to develop a thermoelectric-based alternative cooling system. The cooling system is in the form of air ducts with 6 and 12 varied TEC 12706 either without evaporative cooling or a combination of evaporative cooling. Temperature measurements were taken in real time using a temperature data logger. The temperature of the cabin parked without a cooling system was 46.3°C. The configuration of dual thermoelectric cooling system and evaporative cooling 0.3 lpm produces the lowest cabin and environment temperature difference of 4.18°C and decreased by 9.54°C compared to without cooling system. The addition of an evaporative cooling system can increase the COP of the cooling system. From the test results, the highest COP is 1.07 in the configuration of the 0.3 lpm evaporative cooling system (PE), but the Tavg cabin is still high, which is 44.34 ° C at Tenv 38.13°C, which results in a temperature difference and an environment of 6.17°C. Meanwhile, the configuration of thermoelectric cooling and evaporative cooling 0.3 lpm produces a difference in cabin temperature and the environment of 4.15°C, with an Tavg cabin of 36.73°C at Tenv 32.58°C with a COP of 0,62. Keywords: thermoelectric, evaporative, heat transfer, refrigeration machine
