Project ini membangunkan sebuah sistem penyaman udara untuk kegunaan kereta menggunakan tenaga solar berdasarkan penggunaan peranti penyejuk Termoelektrik. Pembinaan sistem ini terdiri daripada dua buah Panel Solar yang disambung secara selari sebagai sumber tenaga kepada kesuluruhan sistem, peranti penyejuk Termoelektrik sebagai sumber penyejukan, litar injak turun arus terus sebagai litar pengawal dan kotak peniup untuk meniup udara sejuk kepada penumpang di dalam kereta. Litar injak turun arus terus dicipta untuk menurunkan voltan dan arus terus dari panel solar untuk kegunaan peranti penyejuk termoelektrik. Tiga buah peranti penyejuk termoelektrik yang disambung secara sesiri dilekatkan kepada kumparan pendinginan di sebelah sejuk dan tiga buah penenggelam haba yang berasingan digunakan untuk mengeluarkan haba dari peranti penyejuk termoelektrik. Kotak peniup dengan lebar 30cm, tinggi 13cm dan panjang 33cm direka untuk menempatkan kumparan pendinginan dan kipas paksi 24V. Litar injak turun arus terus direka menggunakan perisian Proteus 7 dan perisian ORCAD digunakan untuk menyiapkan Papan Litar Bercetak (PCB) untuk litar tersebut. Sistem yang direka ini dapat meniup udara sejuk keluar dari kotak peniup dengan beza suhu sebanyak 6.6°C daripada suhu persekitaran. Litar injak turun arus terus yang direka mampu mengawal voltan dari 1.05V sehingga 8.16V dengan dua solar panel yang disambung secara selari sebagai punca bekalan.

The projects present the development of solar based Car Air Condition System using Thermoelectric Cooler. The construction of the project is consists of two parallel connection of Solar Panel as a source, DC-DC Step Down Converter as a control circuit, Thermoelectric Cooler as Cooling Source and the blower to blow cooling air to the passenger inside the car. DC-DC Step down Converter designed to regulate the voltage and current from the Solar Panel to the TECs. Three series connection of TECs were attached to the Cooling Coil as a cold sink and three different heat sinks were used to release heat from the TECs. Blower with dimension of 30cm width, 13cm height and 33cm length were build to place the Cooling Coil with the axial fan 24V. The DC-DC Step down Converter was designed using Proteus 7 software. ORCAD software was used to design the converter. The developed systems are able to blow out cooling air from the blower with 6.6°C in temperature different with the ambient temperature. The DC-DC Step down Converter that has been designed capable to regulate voltage from 1.05V up to 8.16V and can provide a current up to 5A with two parallel connection of solar panel as a source.
