Abstract
Given the extreme hot and humid ambient conditions of UAE, it comes no surprise that the demand for air conditioning would increase rapidly. In the UAE, roughly 90% of the electricity is consumed by the building sector. In that sector, air conditioners (A/Cs) consume about 80% of the total annual house electricity. The fact that performance of A/Cs decreases as the ambient temperature increases. Additional challenge to optimize energy consumption is that in hot and humid regions A/C units are simultaneously required to control the temperature and humidity. Thus, oversized A/C units are usually used which increases the energy consumption and affect indoor thermal comfort. This study aimed to analyze the implementation of the ASHRAE standard in a residence in Dubai. Transient System Simulation (TRNSYS) program is selected to study a detailed analysis of a residential building implementing ASHRAE building standards. The goal is to reach to an indoor temperature of 22.5°C and a 50% relative humidity according to ASHRAE standards. The values obtained from running the simulation over all the zones can now be used in order to size the A/C system. The maximum required load for all zones is 59.6 kW, however after applying the optimization method it was reduced by 4,5% to reach 56.9kW.
