Carrier unveiled its latest innovation, the new AquaEdge® 19DV centrifugal chiller with Greenspeed® intelligence and a low Global Warming Potential (GWP) refrigerant. The breakthrough technology is being introduced in North America for the first time and delivers on customer demands for excellent performance, leading efficiency, and environmental responsibility.
Improvements in compression technology and integration of Carrier’s Greenspeed intelligence variable-speed technology enabled Carrier to significantly improve its centrifugal full- and part-load efficiencies. The result is the high-efficiency AquaEdge 19DV centrifugal chiller that saves energy costs and reduces environmental impact.
The advanced 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 low-speed direct drive back-to-back design significantly improves efficiency while balancing internal forces, enabling the use of energy-saving ceramic bearings that utilize the refrigerant already in the chiller as lubricant. The intuitive touch screen user interface provides graphical trending and remote access capability and can be mounted on any corner of the machine. Its simplicity, flexibility and performance make the AquaEdge 19DV easy to own and operate.
PIC5+ controls for intelligent chiller management
Equipped with Carrier’s latest achievement in PIC5+ intelligent controls, and integrated with the Carrier lifecycle data management system, the AquaEdge 19DV allows users to easily 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 now experience a new level of equipment connectivity solutions including: remote diagnostics, long-term performance trending, benchmarking, decision analytics, and advanced notifications. By leveraging new insights derived from these capabilities, Carrier SMART Service can help improve equipment reliability and reduce energy usage, maintenance expenses and resource consumption.
High operational flexibility to respond to demanding situations
The AquaEdge 19DV adopts multiple technologies to optimize itself for robust operation in various demanding scenarios. For instance, the Greenspeed intelligence, together with the unique compressor design that deploys one inlet guide vane for each of two stages, supports stable chiller operation at all times, even at 10% part load. This means consistent performance during off-peak hours in office buildings where computers operate at night. Also, PIC5+ controls allow swift restart in just 30 seconds in case of an unexpected power failure. This is extremely important for businesses like data centers where downtime can negatively impact their operations and bottom line.
