This would overcome concerns regarding the perceived risk of standardised components and product recall.
It’s not acceptable, she says, addressing the position of the serial owners who are building hospital after hospital, school after school.Owners who are spending billions of dollars.. “What owner in their right mind is going to spend money and not get consistency of any data,” she says, “to learn from, reuse and evolve, to be more operationally efficient?
How could that be acceptable?”.“We find the same thing”, says Jaimie Johnston.“It's serial custo.
mers who are dissatisfied with either the quality they're getting or the value they're getting.”.Johnston says that the biggest value driver of them all is climate change and carbon.
He agrees that there’s a “dawning recognition” that we don’t have a choice.
However, these days, the data is starting to allow us to do these things, making this particular moment in industry history different from the ones that have come before.. “I think that's why it might stick this time,” he says.An efficient heat rejection system design is limited by the following parameters:.
Supply air/water temperature:.the design temperature the cabs/racks/CDU require during normal conditions..
Peak summer and yearly external temperatures:.the design temperature the external heat rejection equipment must be rated to, typically there will also be an additional allowance for recirculation for multi-unit installations (usually validated by an external CFD based on extreme temperatures and wind conditions)..
