Parked Car Thermal Management and Air Quality System 2021-28-0150

The motivation of this work is to respond to high cabin temperatures within a parked/stationary vehicle which may cause discomfort and lead to vehicular heatstroke. The system also intends to ensure sufficient limits of oxygen within the vehicle cabin to prevent asphyxiation to the cabin occupants. The rise in global temperature is affecting the quality of air and comfort of occupants inside a parked car. There have been several cases reported of pets and children being left unattended or unsupervised in a parked car for a long period of time which have led to their deaths due to asphyxiation. The use of cost-effective materials like high density plastics for interior cabin trim have also been proven to contribute to cancer because of the emission of benzene a carcinogen by these plastics when exposed to extreme temperatures for long periods of time. This paper proposes a system where an oxygen sensor is used to measure oxygen levels within the cabin and an arrangement to lower the windows when a low level of oxygen is detected. The system also includes a temperature sensor with a suction and blower fan arrangement where the suction fan pulls the hot air out and the blower fan pushes fresh air in. This air flow will ensure air circulation in a parked car and prevent the stagnation of hot air within the vehicle cabin. It was also a crucial factor that this system should not interfere or hinder with any other workings of the car. This system will be powered by a compact solar system.
