Case Study: Hamad International Airport


Hamad International Airport is the international airport of Doha, the capital city of Qatar. It replaced the former Doha International Airport as Qatar’s principal airport.

Hamad International Airport


Hamad International Airport is a leading International Airport in the world welcomes around 30 million passengers per year. The facility receives chilled water supply from 4 main Central Utility Plants named as CUP-1, 2, 3 & 4, with total installed load of 50,000TR


Presently the condenser pumps are running with full speed and the VFD is bypassed. Pump is running full load of 100%, designed BKW is 154.4 kW and actual power consumption is 154.87 kW, designed flow rate of pump is 1500m3/hr & actual flow rate is 1817m3/hr. The power consumption & flow rate for the condenser pumps in CUP 2 & 3 is higher compared to design.



It is recommended to operate VFDs with limiting the maximum speed. This leads to reduced in pump flow and reduces the pump power consumption. By this VFD limiting speed easily 10 kW reduction per pump is envisaged.


Annual Electrical Energy Savings : 262,800 kWh/year

Annual Cost Savings : 57,816 QAR/year

CO2 emission Reduction :130 tons/year
