AquaForce®
30KAV

Air-Cooled Liquid Chiller
with Greenspeed® Intelligence
with R-134a Refrigerant

Sizes 500-1100

The AquaForce™ Vision 30KAV liquid chillers with Greenspeed™ Intelligence are the premium solution for commercial and industrial applications where installers, consultants and building owners require superior reliability and optimal performances, especially at part load.

The 30KAV units are designed to exceed European Ecodesign directive requirements in terms of energy efficiency, versatility and operating sound levels. This result is achieved through the optimised combination of proven best-in-class technologies that include:

  • 2nd generation of high-efficiency variable-speed twin screw compressors with built in volume index control (Vi) valve for optimal full and part load performance and Integrated Resonator Array (IRA) for low sound operation.
  • 6th generation of Carrier Flying Bird™ fans with AC or EC motor depending on options.
  • Carrier flooded shell-and-tube evaporator with new copper tubes for low pressure drops
  • 3rd generation of “W” profile Carrier Novation™ microchannel heat exchangers with optional Enviro-Shield coatings.
  • Carrier Touch Pilot® control with color touch screen user interface that includes 10 langages and new smart energy monitoring.

Performance Features

  • The 30KAV with High Energy Efficiency+ option is equipped with EC fans and additional heat exchange surface to provide the highest possible seasonal energy efficiency. (Average SEER of 5.45, average EER of 3.4)
  • 2nd generation of Carrier high-efficiency variable-speed twin-screw compressors with built in volume index control (Vi) valve for both optimal full and part load performance Variable-speed Flying Bird™ fans with EC motor minimizing power consumption while delivering optimum air flow.
  • Novation™ aluminum condenser with high-efficiency micro-channel coils technology.
  • New Carrier flooded shell-and-tube evaporator with new copper tubes for low pressure drops.
  • Negligible start-up current (value is lower than the maximum unit current draw).
  • Variable-speed, dual pumps which automatically adjust the water flow to match the needs of the building or process load variations.
  • Innovative smart energy monitoring providing users with smart data such as real time electric energy consumption, cooling cooling capacity, and instantaneous and average seasonal energy efficiency ratios.

Reliability features

  • 2nd generation of variable-speed twin-screw compressors:
    • The screw compressors are industrial-type with oversized bearings and motor cooled by suction gas, with a proven failure rate lower than 0.1%.
  • Air-cooled compressor variable-speed drive (VSD) to ensure reliable operation and easy maintenance.
  • All components related to the compressor assembly are easily accessible on site minimising down-time.
  • 30KAV is fitted with variable-speed asynchronous fan motors as standard. One variable-speed drive (VSD) is sized to manage a group of fans per refrigerant circuit reducing first cost while ensuring high part-load efficiency.
    • 30KAV with High Energy Efficiency+ option is fitted with variable-speed EC fan-motors. Each EC fan is controlled independently ensuring continuous chiller operation in case of motor or drive failure.
  • Novation™ aluminum micro-channel heat exchanger (MCHE) with high corrosion resistance.
  • Control algorithm prevents excessive compressor cycling (Carrier patent).
  • Automatic compressor unloading in case of abnormally high condensing pressure. If condenser coil fouling or fan failure occurs, the Aquaforce continues to operate, but at reduced capacity.
  • To design critical components and sub-assemblies to minimise the risk of failure on site, Carrier uses specialised laboratories and advanced dynamic simulation tools.
  • To maintain unit performance throughout its operating life, whilst minimising maintenance costs, end users can access the “Carrier Connect” remote monitoring service.

Maintenance Features

  • Discharge line shut-off valve and liquid line service valve for simplified maintenance.
  • New 06Z twin screw compressor optimized for variable speed operation: elimination of the slide valve, built in volume index Control (Vi) valve for both optimal full and part load performance, high efficiency AC motor with stepless inverter control from 20% to 100%
  • Aquaforce with Greenspeed® Intelligence is equipped with an RS485 serial port that offers multiple remote control, monitoring and diagnostic possibilities.
  • The 30KAV also communicates with other building management systems via optional communication gateways (BACnet, LON or JBus).
  • A dedicated oil separator is installed at the discharge of each compressor to ensure maximum oil return: Oil separates from refrigerant by gravity and returns to the low pressure side of the compressor without use of additional pumps.

Options

  • Low noise to Very low noise EC fans.
  • Compressor discharge valves.
  • Jbus & Lon gateway; Bacnet over IP.
  • Enviro-Shield & Super Enviro anti-corrosion protection.
  • LP & HP VSD dual-pump hydraulic mod. From 500-800.
  • High Energy Efficiency+
  • Variable water flow control
