The problems and dangers caused by the increase in the internal temperature of the cabin as a result of parking under the sun due to the phenomenon called the greenhouse effect and the disadvantages of existing conventional methods to reduce the temperature, such as: Increasing fuel consumption, being expensive, creating environmental problems, etc., necessitates the design of a cost-effective and clean system with easy use in order to adjust the internal temperature of the car cabin.
The purpose of this invention is to create thermal adjustment inside the car cabin by using phase change materials in the car interior. In this system, the internal parts of the car can adjust their thermal resistance automatically with the ambient temperature. By incorporating phase change materials in these parts, when the temperature increases and passes a certain limit, the excess heat is absorbed by the PCMs in the parts, and this absorbed energy is spent on the process of changing the phase of the PCMs from the solid phase to the liquid phase (at a constant temperature). ) becomes This process leads to a decrease in the temperature of these parts, and as a result, the release of heat energy from these surfaces decreases, which ultimately leads to the adjustment of the internal temperature of the car cabin. In addition to adjusting the internal temperature of the car and increasing the thermal comfort of the passengers, this system reduces the need for air conditioning systems (A/C), reduces fuel consumption, and reduces harmful emissions.
