Cooling With Less Carbon: Why AC Servicing is Dubai’s Most Underrated Climate Action

Air conditioning is expensive. Any Dubai summer electricity bill says so. What the bill hides is the carbon. Every kilowatt-hour consumed by a compressor in Al Barsha or Deira traces back to a power station, and for much of the year a large slice of the emirate’s generating capacity exists to keep indoor air cold. How that equipment is looked after, whether it’s a split unit on a villa wall or a chilled-water plant feeding a tower on Sheikh Zayed Road, decides how much fuel the city burns for the same degree of comfort. There is a quiet argument here … Continue reading →

Trigeneration Systems: Working Principle and Benefits

Trigeneration refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a biomass fuel or a solar heat collector. Conventional coal or nuclear-powered power stations convert only about 33% of their input heat to electricity. The remaining 67% emerges from the turbines as low-grade waste heat with no significant local uses so it is usually rejected to the environment. What is Trigeneration In a trigeneration system, the supply of high-temperature heat first drives a gas or steam turbine powered generator and the resulting low-temperature waste heat is then used for water or space heating. Such systems can attain higher … Continue reading →

District Cooling in Middle East: Potential and Challenges

District cooling produces chilled water in a centralized location for distribution to buildings, like offices and factories, through a network of insulated underground pipes. The chilled water travels to different buildings, where the water circulates through refrigeration coils or uses absorption technology to enter the air-conditioning system. During winter, the source for the cooling can often be seawater, so it is a cheaper resource than using electricity to run compressors for cooling. What is District Cooling District cooling provides effective control over internal temperature of a building, requires less maintenance than a standalone air-conditioning system, consumes lesser space and reduces … Continue reading →
