Jacqui discusses how construction can learn from more integrated sectors like aerospace and automotive, where industry voices are more unified and the government provides more substantial support, allowing for quicker advancements.. 5.
The larger the temperature difference, the harder the mechanical cooling system must work.Compared to free cooling, mechanical cooling requires substantial electrical input, which ultimately contributes to more heat being rejected.
This can further increase water consumption if the heat rejection plant utilises adiabatic cooling.. Reducing the mechanical cooling demand.The obvious, although usually impractical, way would be to locate the data centre in a colder climate where the average temperature is lower, allowing for free cooling to operate for longer and reducing the mechanical cooling hours operated.This won't be practical for most data centre operators due to cost, land, power and connectivity availability.. A more practical way to reduce the mechanical cooling demand is by increasing the air/water temperature supplied to the data hall.
For example, migrating to ASHRAE A1 Allowable temperature range from ASHRAE A1 Recommended during peak external ambient conditions could reduce OPEX considerably.. ASHRAE Environmental Classes (Allowable) for Data Centres.Hot and cold aisle separation is standard in all new data centres, however, improved air flow management and hot aisle containment (HAC) leakage reduction can have a positive improvement on air temperatures in the room.. Air Side Economisers.
In data centres operating within ASHRAE A1 Allowance temperature and located in colder/dryer climates, direct evaporative coolers (DEC) are a highly efficient solution, however, they utilise a larger footprint on the site.
These systems can potentially operate in free cooling mode year-round, leveraging both dry and adiabatic cooling based on external conditions.If you'd like to continue to learn about our Design to Value approach and Modern Methods of Construction, sign up for our monthly newsletter here:.
http://bit.ly/BWNewsUpdatesDeveloping our Design to Value approach as pharmaceutical plant design consultants.In 2012, Bryden Wood and GlaxoSmithKline started working together to try and come up with a different approach to pharmaceutical capital projects.
We started from the premise that while a great deal of effort was expended by a lot of expert people within both pharmaceutical and engineering companies, and despite the significant sums being spent, capital projects often failed to meet business requirements.And how could we do better in our approach to pharmaceutical facility design?.
