Cannon Water Cooling solutions work on the air to water heat exchanger principle:- Warm air from a cabinet, room or aisle is forced through a heat exchanger fan coil by high efficiency fans.
The heat exchanger has chilled water at between 7º and 20ºC circulating within it’s coil, the chilled water is supplied by an external main system water chiller(s) (not included). The heat in the warm air will naturally dissipate into the fins of the coil as they are colder than the air, by this process the heat is ‘exchanged’ with the cold water circulating counter currently in the coil.
The now cold air is carried out of the coil and blown into the cold aisle or cabinet. The water that has been warmed by the heat exchanger coil is returned to the main system chiller loop though a variable flow control valve (optional automatic). Performance of the system is dependant on many climatic and environmental conditions:-
The Computer room should be sealed from outside heat sources and fresh air minimised within reason. Any open spaces to the sides of the 19-inch racks should be blanked and all wiring taken to the sides of equipment to keep the airways to and from the equipment fans open. The equipment within the the cabinet rack spaces should have it’s airflow maximised. All unused rack space should be blanked off.
Cannon computer rack cabinet/aisle water cooling systems are not traditional air conditioners, they do not regulate humidity. In humid atmospheres they will remove water vapour and condensate when the humidity level is high. The condensate drain should be run to a normal gravity drain sump. An optional condensate pump may be fitted if required. In some situations the room humidity may be too low, and static electricity may cause a hazard to persons and equipment. The climate inside a data centre should meet the standards set by ASHRAE. For further details visit the Cannon website.
Cannon equipment is designed and built to comply with BS EN60950 and the low voltage directive/SELV where appropriate. Any installations must meet local building and electrical supply regulations where applicable.
