Carrier has officially launched the new AquaEdgeTM 19DV centrifugal chiller with GreenspeedTM inverter technology and PUREtecTM low Global Warming Potential (GWP) refrigerant. The chiller was previewed at the China Refrigeration Expo from 12 to 14 April in Shanghai by Shanghai Yileng Carrier Air Conditioning Equipment Company Ltd. Carrier is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).
The breakthrough technology is now available commercially for the first time. It delivers on customer demands for excellent performance, leading efficiency, and environmental responsibility, due in part to the use of environmentally-sustainable R1233zd(E) refrigerant, which has a Global Warming Potential (GWP) of 1.34.
“The AquaEdge 19DV centrifugal chiller is illustrative of Carrier’s ongoing commitment to innovation and technology leadership through the development of energy-efficient, reliable and environmentally-responsible solutions to serve different segments,” said Gaurang Pandya, President, Asia Pacific, UTC Climate, Controls & Security. “From high-end office buildings to hotels, hospitals, data centres and factories, this chiller is the optimal choice to create a more sustainable building environment.”
High efficiency makes it an ideal energy-saving solution
The AquaEdge 19DV features advancements in refrigeration, mechanical design, aerodynamics, and heat transfer to provide efficiency improvements of up to 7.0 COP full load, and 11.8 IPLV.IP as rated in accordance with and certified by AHRI 550/590-2015 at standard rating conditions. In particular, the back-to-back compressor offers excellent compression efficiency, with an optimised design. It simultaneously cuts down 75% of the mechanical transmission loss by using a high-speed direct-driven motor, as compared to being gear-driven.
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 track and analyse the chiller’s operational data easily, which helps 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 real-time running data.
High operational flexibility to respond to demanding situations
The AquaEdge 19DV adopts multiple technologies to optimise itself for robust operation in various demanding scenarios. For instance, the Greenspeed™ inverter technology, together with the unique compressor design, which 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 centres, where downtime can impact their operations and bottom line.
