Abstract: The current paper discusses a new thermoelectric ventilating system that can operate on a 12V 7Ah Lead Acid-Battery using solid-state thermoelectric modules and which is capable of providing reliable and low noise cooling services without necessarily involving the use of traditional types of refrigerants in order to meet the international demand for environmentally friendly and energy-saving cooling systems. Integrating advanced control algorithms and a microcontroller platform, the system is dynamically adjusted to the real-time data related to the characteristics of temperatures and humidity and, accordingly, the cooling supply and airflow are optimally controlled to reduce the amount of consumed power and, consequently, the battery life. The experimental evaluations demonstrate the capability of the system to reduce the interior temperatures by less than 25 degrees Celsius under unfavorable ambient conditions, and maintain operational independent features with capable control of the battery. Although the natural cooling power and material stability of Peltier devices cause limitations to its usage, this off-grid, battery-powered cooling system is highly promising as a sustainable, off-grid cooling system. This paper suggests further developments in the thermoelectric material science and system design, to enhance its functionality and increase its utility in many, energy-prohibited settings.
