In this job, my responsibility was to ensure that the required basics are present in the pilgrims’ accommodation sites in the holy sites, and this applies to electricity, water, and even security and safety. And one of my tasks was to contact those who fix any defect that may occur in the housing areas. I was also following up with the Ministry of Hajj on the needs of the residential sites and making sure that the sites are completely ready. The residential sites contained more than 4,000 pilgrims in the holy sites, and all services were provided to the fullest.

The work was during the Hajj season, which corresponds to August. The nature of the work was to guide the pilgrims and guide them according to the instructions given, and take into account the times of prevention. Our mission is to take the pilgrims to the Jamarat safely and to make sure that all the pilgrims return to the Mina camps safely.

In the graduation project, I used the Aspen Hysys simulation program, designed the air conditioning cycle in cars, and conducted studies under some conditions to test the performance of each refrigerant in the project. The goal was to choose the best refrigerant gas in terms of performance, price, cost, and impact on the environment.
