Installation of a  Toshiba server room air conditioning system for BCA car auctions Corby Northamptonshire.

Orion air conditioning has completed the installation of a Toshiba server room air conditioning system for BCA car auctions in Corby. The system was to cool the main servers for the BCA site which were used for the entire business operations of the car auction site.

Toshiba air conditioning units are renowned for long reliable life span and are ideal for server rooms and Comm's rooms were a failure can mean the complete shut down of an entire businesses operation or at worst damage to the server equipment. The Toshiba air conditioning systems are robust commercial equipment which are not only energy efficient but also offer high COP's and modulated dc inverter compressor which can save up to 40% on server room air conditioning that can run 24 hours / 7 days a week. 

Pictures of the project:



What air conditioning units were installed in the server room:

1 Toshiba wall mounted 3.5kW / 12000 Btu) which provided enough cooling for the 10 meter square area and 2  server racks in the server room with spare cooling capacity in case of future expansion of the server equipment. The Toshiba wall air conditioning units are found worldwide and have a amazing COP (3.81 x initial electrical input) which means that every 1000w of electrical energy going in produces 3810 watts of cooling output. This equates to a A++ energy rating.

Server room air conditioning efficiency and CO2 emissions:

This Toshiba air conditioning system, because slightly oversized for the area,  meant we had spare capacity in case of any expansion on any of the server racks.

Power / Heat-Loss Summery:
Server room efficiency: 85% approximately 
Total power of servers: 10000 Watts
Total heat loss: 1250 Watts@85%
Room in Square Meters: 1000 Watts
Total Heat Load Required: 2250 Watts
Key points to think about when getting air conditioning for server rooms:
  • Use inverter air conditioning as it will save energy in the long run.
  • Always follow the ASHRAE’s Design considerations for data and communications equipment centres guidelines towards humidity
  • Cheap air conditioning units do not work in cold weather because they do not have a outside fan speed controller (low ambient kit)
  • Use a established brand so if a part fails on you Server room air conditioning you are not waiting 8 weeks for a spare part.
  • Sometimes it is worth having two server room air conditioning units because if one fails you still have some cooling.
  • To establish the heat load of you servers add up all the power supplies of your servers rack and assume a 40% loss to heat. i.e- If you have 10 servers with 400watt power supply the total watts will be 4000 watts. assuming a 40% loss the heat load will be 1600 watts.
  • Work on a average watts per/Msq of 125watts, so if you server room is 5 x 5 meters you will require a base of 3.5kw/12000btu + the heat load.
  • Advised manufactures for server room air conditioning Mitsubishi, Daikin, Fujitsu and Lg
  • Always use auto-restart units for server room air conditioning units as power failures can shut budget air conditioning down.
  • If your server room is temporary (ie short term lease on building) or has building restrictions then portable air conditioning maybe your only option.
  • If using portable air conditioning for your server room then make sure it recycles the water for better cooling performance of that it has a integral condensate pump.
  • Use a established business who will not be going out of business for your server room air conditioning installation as the warranty of the air conditioning is with the supplier not the manufacturer.
