How our cooling systems got cooler
Have you ever heard of an entire building used as a live lab for real-time comparative analysis, that too in a corporate organization’s campus?
Yes, that's right – we have an entire building that is being used as a live-lab. Read on to know more...
为什么？
In our Indian campuses, air-conditioning contributes to a staggering 40% of the energy consumption of our buildings and eventually to our carbon footprint. To reduce our carbon and energy footprints, we wanted to test the effectiveness of the pioneering, environment-friendly Radiant Cooling system.
The goal of the experiment was to find out if the Radiant Cooling technology is more sustainable and efficient compared to conventional cooling systems.
What we did about it?
We carried out one of the world’s biggest and ‘first-of-its-kind’ experiments in comparing conventional systems with the Radiant Cooling system in a new building on our Hyderabad campus.
We challenged existing practices and took a radical approach to air conditioning by successfully experimenting with the Radiant Cooling technology.
With the most efficient conventional system: Per capita energy consumption is78KWH每月
With Radiant Cooling system: Per capita energy consumption is57KWH每月
What is radiant cooling?
Radiant cooling is a system that uses a temperature-controlled surface to cool indoor temperatures by removing heat, mainly through the radiation mode of heat transfer. In this mode, heat flows from warmer objects, occupants, and equipment to a cooled surface.
The cooled surfaces, in this case the building floor and ceiling surface, provide cooling. Pipes carrying chilled water are embedded in the concrete slab or in the building’s false ceiling at the time of construction. As water can carry 3,400 times more heat than air for the same volume, it makes Radiant Cooling far more efficient compared to air-based cooling systems. The system uses fresh air supply for ventilation and moisture removal.
How we implemented Radiant Cooling?
当我们首次考虑在2007 - 08年左右采用辐射冷却技术时，它在世界上相对较新，并且从未在印度在大型商业空间中实施。
- 在海得拉巴的Live-Lab中，我们将建筑物的一半设计为辐射冷却，另一半则使用传统的冷却方法。所有其他参数，例如面积，乘员数量，照明，建筑定位，建筑信封等，两半都相同。为了在辐射冷却和常规系统之间进行明确的比较，我们跟踪了一年的数据，并获得了激进的见解。
- 辐射冷却pipes were laid in the concrete slabs during building construction. These pipes circulated chilled water to keep the floor and ceiling cool.
- Fresh air was circulated through an air system to keep the indoor environment healthy and the humidity in control.

Radiant Cooling was 30% more efficient compared to the most efficient conventional systems, and additionally, enhanced indoor air quality and thermal comfort.
We have a total area of 5 million sq. ft. with Radiant Cooling across PAN India Infosys
相信我们可以使我们的辐射冷却解决方案具有成本效益，并且与市场上可用的装置相比，我们制定了一项计划，以在内部开发这项技术。这导致了Radiflux Radiant冷却面板技术的开发，这是IT公司的“独一无二”创新！
