Industry/Government/ Academia Partner to Achieve SCOP > 5 Hot-Climate MEPS Air-Cooled Chiller

摘要

Urbanization is driving rapid growth of mechanical cooling around the world, much of it in hot climates. Adoption of minimum energy performance standards can significantly reduce global growth of electricity demand assodated with cooling. Performance standards aim to minimise equipment life-cycle cost by setting performance levels appropriate for a given climate. A typical UAE 8760-hour cooling load profile is developed. A component-based chiller model is validated by monitored data from a baseline chiller that meets the highest MEPS currently in effect of SCOP-3.5 W / W. Performance maps are produced for a series of progressively higher performance chiller designs and ECC analysis is carried out using component costs and annual simulation results until the least life-cycle-cost design is found. A high performance air-cooled chiller minimum performance level of SCOP>5.0 W / W is life-gcle cost-effective in UAE's hot climate.
