Load testing to ASHRAE TC9.9

Posted By Paul Smethurst, Hillstone Products, 28 October 2015

ASHRAE TC9.9 promotes operating IT equipment at higher ambient temperatures to reduce the running costs of datacentre cooling systems.

In order to incorporate these recommendations datacentre designers and operators need to be able to replicate maximum expected environmental conditions during IST commissioning programs. 

TC9.9 defines two temperature criteria which must be part of any IST commissioning program. 

-       The first criteria being the cold aisle operating temperature range of 18°C - 27°C  /  64°F - 80°F

-       The second criteria defines the maximum operating temperature of 40°C -45°C / 104°F - 113°F for commercial grade IT equipment

Often commissioning managers complain of load banks cutting out due to temperature overload thermostats and subsequent difficulties of establishing a consistent temperature in the datahall when trying to meet the temperature range of testing to TC9.9. 

These load banks will therefore prevent the IST from demonstrating failure of the cooling system and the time period for the temperature rise to reach the maximum operating temperature for commercial grade IT equipment.

Hillstone’s HAC230-6RM server simulator load banks are designed to operate in accordance to TC9.9 over a wide temperature range to prove the successful operation of the datacentre during stress testing of the HVAC system.   

This includes:

-       operating the cold aisle at  18°C - 27°C  /  64°F - 80°F

-       determining the runtime to 40-45°C / 104°F - 113°F

-       creating a delta T range from 6°C to 20°C  / 43°F - 64°F

 

Hillstone datacentre services can supply the 6RM from its UK & Middle East rental depots

 

The Hillstone load bank and IST package will allow IT managers to build SOP and staff training programs the for mission critical equipment
