Long-term performance of a hybrid indirect evaporative cooling-mechanical vapor compression cycle: A case study in Saudi Arabia

In Saudi Arabia, air conditioning is the main consumer of electricity, and increasing its energy efficiency great importance for conservation carbon footprint reduction. This study presents evaluation a hybrid indirect evaporative cooling-mechanical vapor compression (IEC-MVC) cycle cooling applications in Arabia. Most cities this country are characterized by high sensible demand, few near coasts Red sea Persian Gulf also need dehumidification. By employing system, IEC can undertake about 60% load summer arid cities, consumption be reduced up to 50%. The contribution saving less significant humid because latent loads have handled MVC. Over whole year, contributes 50% total capacity reduces 40% dry while lower at 15%–25% like Mecca Jeddah. average water range 4–12 L/hr. replenished condensate collected from MVC evaporator if ambient humidity high. Based on annual performance, cost IEC-MVC process calculated, it 15%–35% than standalone results demonstrate potential
