The increasingly competitive market and the recent economic conditions have led to a rise in the number of critical telecom facilities being served by traditional comfort cooling. Comfort cooling systems are indeed attractive with their low upfront costs. However, with careful thought, comfort cooling systems are not what they first appear.

Telecom equipments generate heat and their components are very sensitive to temperature changes, humidity and the presence of dust. With that being the case, sensitive electronics require simultaneous control of temperature, humidity, air motion and cleanliness in a specified area, continuously and accurately.

The basic features found in comfort cooling systems, however, do not address the operational requirements of sensitive electronic equipment such as that found in BTS/BSC sites, media centers and exchanges.

Here’s a quick comparison between the two cooling systems:

Precision Cooling • Primarily conditions critical applications • High sensible heat, 0.9SHR • Has temperature & humidity control and air filtration • Addresses high heat loads • Supports 24/7 operation • Critical on serviceability and support

Comfort Cooling • Primarily conditions people • Low sensible heat, 0.6SHR • Temperature fluctuations occur • No humidity control, low air filtration • Supports 1,000 – 2,500 hr/yr operation • Low consideration on serviceability and support
