New Line of Commercial Aaon Heat Pump Condensers are a Hit

Posted by

In February we finally got to see our new line of Aaon CF heat pump condensers in action.  The first of several new installations in Nova Scotia was comprised of four CF-20 outdoor heat pump condensers, each with two 10 ton refrigeration circuits connected to four of our DX2W-3 20 ton indoor split modules.  This 80 ton installation is at the new Velo apartment building complex at 2300 Gottingen Street in Halifax which features 105 apartments, 9 retail spaces and a 2nd phase in the future expanding the complex by 50% requiring another 60 tons for a total size of 140 tons.   The new Aaon rooftop condensers are much quieter, powerful and energy efficient than previously used condensers and monitoring data has shown that they are outperforming our projections, promising customers quicker payback, greater savings and longer expected longevity.

The hydronic design we came up with for this project required us to locate the condensers up on the roof along with our DX2W-3 modules but keep the heavy and bulky storage tanks, domestic hot water and backup boiler in the parking garage mechanical room.  This was accomplished by using a 6" diam low loss header to connect the rooftop and parking garage mechanical rooms along with a smaller 3" loop for domestic hot water preheat.  Our building automation platform controls and monitors the eight 10 ton refrigeration stages, 1 MBTU natural gas boiler, 3 x 175 USG stainless steel buffer tanks, 3 x 120 USG stainless steel indirect water tanks for preheat along with another 3 x 120 USG stainless steel indirect tanks for domestic hot water top-up and storage and finally a snow melt system.  Eleven Wilo Stratos Smart ECM circulators are used throughout the installation and feature dual heads for redundancy in all mission critical circuits.
