Improvements in compression technology and integration of Carrier’s Greenspeed intelligence variable-speed technology enabled Carrier to improve its centrifugal full- and part-load efficiencies. The result is the AquaEdge 19DV centrifugal chiller that saves energy costs and reduces environmental impact.
The two-stage compressor was designed and optimized for refrigerant R-1233zd(E), which has a GWP of 1.34 and an A1 safety classification per ASHRAE standard 34. The compressor’s direct drive back-to-back design improves efficiency while balancing internal forces, enabling the use of ceramic bearings that utilize the refrigerant already in the chiller as lubricant. The
touch screen user interface provides graphical trending and remote access capability and can be mounted on any corner of the machine. Its performance make the AquaEdge 19DV easy to operate.
PIC5+ Controls for Intelligent Chiller Management
The AquaEdge 19DV allows users to track and analyze the chiller’s operational data, which helps to identify potential risks or areas for upgrading. The control system can also be linked to
the user’s building automation system, enabling remote access to the chiller’s running
data in real time.
A Smart Connected Chiller With Carrier SMART Service
With the factory-installed addition of Carrier SMART Service, building owners and facility managers can experience a new level of equipment connectivity solutions including remote diagnostics; performance trending; benchmarking; decision analytics; and notifications. By leveraging insights derived from these capabilities, Carrier SMART Service can help improve equipment reliability and reduce energy usage, maintenance expenses and resource consumption.
Operational Flexibility to Respond to Demanding Situations
The AquaEdge 19DV adopts multiple technologies to optimize itself for operation in various scenarios. For instance, the Greenspeed intelligence, together with the compressor design that deploys one inlet guide vane for each of two stages, supports stable chiller operation at all times, even at 10 percent part load.
This means consistent performance during off-peak hours in office buildings where computers operate at night. Also, PIC5+ controls allow restart in 30 seconds in case of a power failure. This is important for businesses like data centers where downtime can negatively impact operations and bottom line.
