| Summary, etc. |
This study focuses on the development of a portable thermoelectric cooler and heater system,<br/>designed to provide an efficient solution for maintaining optimal temperatures in various<br/>environments. The system utilizes thermoelectric coolers (TECs) to regulate the temperature<br/>inside a 5-liter insulated container, allowing it to cool or heat items based on user-defined<br/>settings. Unlike conventional cooling and heating devices, the system operates on DC power<br/>from a vehicle's power supply, making it suitable for off-grid and portable applications without<br/>reliance on refrigerants or external electricity sources. A temperature sensor continuously<br/>monitors the internal temperature, while a fan ensures even air distribution to improve<br/>efficiency. The system was fabricated using locally available materials, keeping costs low while<br/>maintaining durability. Testing was conducted to evaluate the cooling and heating efficiency of<br/>the system under real-world conditions. The results showed that the chiller successfully lowered<br/>the internal temperature from 25°C to 13°C within a specific time frame, demonstrating its<br/>effectiveness in cooling beverages. The heating function utilized waste heat from the TEC<br/>module, efficiently maintaining temperatures suitable for warming food or drinks. Performance<br/><br/>experiments based on workability, effectiveness, aesthetic safety, economy, durability, and cost-<br/>effectiveness. showed that the system met most of this study's objectives. Economics scored<br/>lowest 4.36 and aesthetics highest 4.87 in our overall evaluation, which yielded an average score<br/>of 4.65 out of 5.<br/><br/>Keywords: cooling, heating, portable, sensor, temperature. |
