Dubai Metro: Beating the Heat in Style!

Cool During Summer Heat: Dubai Metro Upgrades AC System

City transit in Dubai remains comfortable for residents and tourists even during the summer months, thanks to a comprehensive upgrade of Dubai Metro's cooling system. The Roads and Transport Authority (RTA) announced the successful completion of the second phase of air conditioning and ventilation system upgrades for the Red and Green line metro stations.

Comfortable 24°C Temperature in Metro Cabins

RTA's goal is clear: to ensure a pleasant 24–25°C temperature for metro users across the entire network, even on the hottest summer days. The authority emphasized that passenger comfort and system reliability are central elements of the maintenance strategy. As a result of modernization, not only has the cooling performance significantly improved, but the system's reliability has also increased, while the metro runs uninterrupted.

The Challenge: Continuous Influx of Hot Air

The region's summer climate is particularly challenging for any mass transit system. The Dubai Metro is especially sensitive due to constantly opening doors: trains stop every 2-4 minutes, allowing hot outside air to regularly flow into the stations. This places considerable demand on cooling systems, which must respond quickly to maintain a constant internal temperature.

What Happened in the Second Phase?

In the now completed second phase, a total of 876 cooling and ventilation units were refurbished across 14 metro stations and two parking lots along the Red line. The work included replacement and renovation of the following key components:

air handling units (AHU),

fan coil units (FCU),

chilled water pumps,

exhaust fans,

smoke extraction units,

pressurization systems.

It is noteworthy that the modernization work did not affect the metro's schedule, meaning passengers could use the service without disruption during the renovations.

Continuous Development and Energy Efficiency

The just-concluded second phase is a continuation of the first phase, which involved 261 units at 13 stations. The RTA has already begun preparing for the third phase, which will focus not only on cooling performance but also on increasing energy efficiency. The aim is to implement variable flow technology in the future to optimize energy use and reduce operating costs.

Summary

The Dubai Metro is now not only fast and reliable but also offers a pleasantly cool travel experience during the summer months. Continuous improvements and the introduction of modern technology allow the city's residents and visitors to travel comfortably, even when the sun blazes outside. The RTA example demonstrates how long-term strategy and technological innovation can prepare for the most extreme weather conditions.
