Data Center Precision AC Rotary Heat Recovery Solution (PUE Optimization)

Project Background

An IDC server room deploys about 2,000 cabinets, and the year-round exhaust continuously carries away large amounts of cooling energy.

Challenges

24/7 cooling is required; PUE stays high and electricity cost is a heavy burden.

Solution

Precision-AC exhaust passes throughRotary Heat ExchangerPre-cools the fresh air and uses part of the recovered cooling for heating adjacent office areas, achieving combined cooling-and-heating utilization.

Results

AHU cooling load reduced by 18%, saving about 1.2 million kWh of electricity per year and significantly optimizing PUE.
