THE DEVELOPMENT OF REMOTE MONITORED MOBILE VACCINE COOLING SYSTEM

While dealing with the daily challenges of the COVID-19 pandemic, everyone is looking to science for a solution in the form of effective vaccine preservation in transportation. According to studies, temperature changes in vaccine storage cause up to 10% of vaccinations to be lost during transport. Especially in rural areas where electricity is relatively limited, making it difficult to maintain the ideal temperature range of 5°C to 8°C for vaccine preservation. This vortex tube refrigeration system includes a vortex tube, a cold box, a compressed air storage tank, compressed air hoses and a cooling coil. The Purpose of this project is for storing vaccine, cooling the vaccines, can be controlled remotely, and can use solar battery as its source of power.This study further evaluates the performance of a cooling system designed for vaccine preservation, focusing on its ability to achieve and maintain stable temperatures over time. The system began cooling from an initial room temperature of 25.0°C, rapidly dropping to 20.0°C within the first 5 minutes, and continuing to steadily decrease to 7.0°C by 30 minutes. Once the desired temperature was reached, the system maintained a consistent range between 4.8°C and 5.4°C for the remaining 30 minutes of the evaluation period, with minimal fluctuations. The results demonstrate the system's efficiency in quickly achieving the target temperature and its reliability in maintaining stable conditions crucial for vaccine preservation. This performance makes it a suitable solution for environments requiring precise and consistent cooling, particularly in vaccine storage and transport applications.
