AquaForce®
30RBM/RBP

Air-Cooled Scroll Chiller

Nominal cooling capacity from 164 to 528 kW

AquaSnap liquid chillers are the best solution for commercial and industrial applications where installers, engineering and design departments and building owners require reduced installation costs, optimal performance and the highest quality.

The new generation of AquaSnap heat pumps feature two new versions:

  • The AquaSnap (30RBM) version features a compact all-in-one package optimised for full-load applications where reduced investment cost (low CapEx) is required. For cold or hot climates, the AquaSnap can be equipped with specific options to operate from -20°C up to 52°C.
  • The AquaSnap Greenspeed® (30RBP) version features a compact all-in-one package optimised for part-load applications where high ESEER/IPLV are required. The AquaSnap Greenspeed®, equipped with a variable speed pump and fans, provides premium part-load efficiency to reduce maintenance costs over the lifespan of the chiller.

Additionally, the low sound levels achieved under part-load conditions can be very beneficial for sensitive acoustic applications. Besides operating efficiently and quietly, the AquaSnap Greenspeed® operates from -20°C up to 48°C as standard.

eurovent-certified-performance

Performance Features

High unit full- and part-load energy efficiency and efficient design of the water side:

  • Eurovent energy efficiency class A or B
  • Standardised Eurovent values in accordance with EN 14511-3:2013 EER up to 3.1 and ESEER up to 4.35 (30RBP version)
  • Multiple scroll compressors equipped with a high-efficiency motor which can exactly match the cooling capacity to the load required
  • Electronic expansion valve enabling operation at a lower condensing pressure and improved use of the evaporator heat exchange surface (superheat control)
  • Condenser with high-efficiency Novation® aluminium micro-channel heat exchangers and Greenspeed® variablespeed fans (30RBP version)
  • Low pressure drop brazed plate heat exchangers (< 45 kPa under Eurovent conditions).

Specific control functions to reduce unit cooling energy use during occupied and unoccupied periods:

  • Internal timer: switches the chiller on/off and controls operation at a second setpoint
  • Automatic water setpoint offset based on outside air temperature or room air temperature (via an option)
  • Floating high-pressure (HP) management
  • Variable-speed fan control
  • Cooling demand limitation.

Reliability Features

State-of-the-art concept

  • Two independent refrigerant circuits; the second one automatically takes over if the first one develops a fault, maintaining partial cooling under all circumstances
  • All compressor components are easily accessible on site, minimising down-time
  • All-aluminium Novation® micro-channel heat exchanger (MCHE) with higher corrosion resistance than a conventional coil.
  • V-coil design to protect the coils against hail impact
  • Optional IP54 protection level for compressor control boxes and cabinet fans to guarantee safe operation in hot, dusty and sandy environments
  • Electronic flow switch. Auto-setting according to cooler size and fluid type.

Auto-adaptive control

  • Control algorithm prevents excessive compressor cycling and reduces the quantity of water in the water loop (Carrier patent)
  • Automatic compressor unloading in case of abnormally high condensing pressure
  • Automatic fan speed adjustment in case of coil fouling (30RBP models)
  • Smooth fan start to increase unit lifetime (30RBP models).

Exceptional endurance tests

  • Partnerships with specialised laboratories and use of limit simulation tools (finite element calculation) for the design of critical components
  • Transport simulation test on an endurance circuit based on a military standard.

Maintenance Features

Shut-off valves on the compressor suction and discharge piping for simplified maintenance (the refrigerant charge can be stored in the evaporator or the condenser during servicing).

Shut-off valves on the compressor discharge piping for simplified maintenance (the refrigerant charge can be stored in the condenser during servicing).

Touch Pilot control (standard)

The Touch Pilot control features advanced communication technology over Ethernet (IP), and a user-friendly and intuitive user interface with 5-inch colour touch screen.

Energy management configuration

  • Monitoring of the cooling and pumping energy consumption via the user interface with optional electricity meter

Advanced communication features

  • High-speed user-friendly communication technology over Ethernet (IP) to a centralised building management system
  • Access to multiple unit parameters.

Maintenance functions

  • F-Gas regulation leak check reminder alert
  • Maintenance alert can be configured to days, months or hours of operation

Installation Festures

Compact design:

  • AquaSnap units are designed with compact dimensions for easy installation.
  • With a length of approximately 4.8 m for 520 kW and a width of 2.25 m, the units require minimum floor space.

Integrated hydronic module (optional):

  • Low- or high-pressure water pump (as required)
  • Single or dual pump (as required) with operating time balancing and automatic changeover to the back-up pump if a fault develops
  • Thermal insulation and frost protection down to -20°C, using a heater (optional)

Simplified electrical connections

  • A single power supply point without neutral
  • Main disconnect switch with high trip capacity
  • 24 V control circuit using an integrated transformer.

Fast unit commissioning

  • Systematic factory test before shipment
  • Quick-test function for step-by-step verification of the sensors, electrical components and motors.

Options

  • Medium / low temperature brine solution
  • Low/Very Low noise level
  • High ambient temperature
  • Winter operation down to -20°C
  • Compressor suction and discharge valves
  • Hydronic module
  • Anticorrosion coating (Enviro-Shield)
  • Super Enviro-Shield anti-corrosion protection
