Malls have large areas and use conventional HVAC to provide comfort cooling to all spaces. This translates to a large amount of energy consumption and operating costs of the building. Specifically, providing cooling in common areas in the malls is a challenge to the mall authorities. Another problem in these kinds of spaces is the quality of the air. The indoor air quality deteriorates due to the re-circulation of air in conventional HVAC systems. Indoor air pollution is much more serious than outdoor air pollution. Each year, 1.5 million people die of indoor air pollution, according to the World Health Organization (WHO).
Radiant cooling systems are a solution for cooling these kinds of spaces.
By using Radiant Cooling system:
1. We are generating chilled water at around 15 to 18 degrees compared to 5 to 8 degrees of conventional HVAC systems, thereby reducing the chiller size. Operations costs are saved by 30 to 50% compared to conventional HVAC systems.
2. The aesthetics of the space is improved by using Radiant Cooling systems.
3. The mall space becomes much quieter and vibrations are absent.
4. We reduce the need for AHU’s and ducts for the circulation of cold air.
5. We maintain a uniform comfort temperature throughout the conditioned space.
6. The air quality of the space is improved air is not recirculated as in the case of conventional HVACs.
The maintenance of radiant cooling systems is simple and cost-effective as minimal resources are used.
In Radiant cooling systems, water is used as a medium to cool rather than air. Water has 3500 times more heat carrying capacity than air. Radiant floor cooling has PERT pipes arranged in loops on the floor through which cold water at around 15 to 18 degrees is circulated, taking away the sensible load in the space.
Malls are places of recreation. It is important that these places are energy-efficient. This helps mall authorities to cut down significant GHG emissions as well as operational costs. Radiant cooling systems provide all of these.
