Commercial / Industrial Air Conditioning

Commercial air-conditioning usually relies on the use of large chillers to distribute cooled water around a building. Cool technologies used in commercial air-conditioning usually involve ammonia for larger chillers and hydrocarbons and carbon dioxide for smaller chillers.

A combination of energy efficiency measures and natural refrigerants could reduce total global emissions from air-conditioning by 40%-60%.

The Dutch bank ABN Amro, uses a CO2 system to cool 15 high-performance servers at the data centre of its London branch. To provide a controlled climate for this hardware, the manufacturer, Star Refrigeration, designed and built a low-energy-consumption CO2 refrigeration system in 2006 to generate a total output of 300 kW. The carbon dioxide is recondensed with water at 6C via an indirect chilling cycle. The cooling is handled by ventilator units on the back of the server cabinets, where the carbon dioxide evaporates at 14C and absorbs the heat siphoned off by the fans. CO2 is reportedly well suited for IT climate control as it does not conduct electricity, helping to increase safety.

Trox Advanced IT Cooling Solutions (AITCS) produces and installs CO2 based data center cooling solutions.
As a heat absorption device, the system removes the PC heat at source, reducing background room cooling to a minimum. The use of ‘non-water’ liquid CO2 eliminates the potential hazards of mixing water and electronics. Per kilogram, CO2 has seven times the cooling capacity of water, so the volume flows with smaller diameter distribution pipework is reduced.
