AquaSnap® 30RBM 160-520

Description

• • Performance Features

    • The 30RBM Aquasnap liquid chillers are designed to meet current and future Ecodesign and F-Gas European regulation requirements in terms of energy efficiency and reduced CO2 emissions. They use the best technologies available today:
    • Micro-channel heat exchangers with new aluminum alloy, Novation®,
    • Low R410-A refrigerant charge below 0.14 kg/kW, through the use of Novation® micro-channel heat exchangers
    • Eurovent energy efficiency class A or B
    • Low-noise scroll compressors with low vibration level
    • Brazed plate heat exchangers with reduced water pressure drops.
    • Auto-adaptive microprocessor control
    • Optional Touch Pilot control with web connectivity possibilities and colour touch screen user display
    • Extra energy savings through multiple options: Direct expansion free cooling system on one or two circuits, hydronic free-cooling system, partial or total heat recovery.
    • With a length of approximately 4.8 m for 520 kW and a width of 2.25 m the units require minimum floor space

    Product Features

    • Multiple scroll compressors equipped with a high efficiency motor that permit exact matching of the cooling capacity to the load
    • Electronic expansion device permitting operation at a lower condensing pressure and improved utilisation of the evaporator heat exchange surface (superheat control)
    • Condenser with high-efficiency aluminum micro channel heat exchangers, Novation® .
    • Low pressure drop brazed plate heat exchangers (pressure drops < 45 kPa at Eurovent conditions).
    • High unit full and part load energy efficiency and efficient design of the water side
    • Specific control functions to reduce unit cooling energy use during occupied and unoccupied periods
    • Greenspeed® variable-speed pump to reduce pumping energy use up to 2/3 (option recommended by Carrier)
    • Elimination of the energy losses caused by the water flow control valve by the electronic setting of the nominal water flow
    • Energy savings during stand-by periods or part-load operation by automatic water pump speed reduction.
    • Pump motor energy use varies as the cube of the speed so that only 40% speed reduction can reduce energy consumption by 80%
    • Improved unit part-load performance (SEER increased SEER value with variable water flow following EN14825).
    • Condenser coils in V-shape with an open angle, allowing quieter air flow across the coil
    • Low-noise 4th generation Flying Bird fans, made of a composite material (Carrier patent)
    • Rigid fan installation for reduced noise (Carrier patent).

    Maintenance Features

    • Fast diagnosis of possible incidents and their history via the control
    • R-410A refrigerant is easier to use than other refrigerant blends
    • Over 15 diagnostic functions
    • Permanently lubricated fan motor bearings
    • Compressor suction service valves (option)
    • Quick-test function for step-by-step verification of the instruments, electrical components and motors
    • Service contract available
    • Qualified Carrier service people for refrigerant servicing

    Installation Features

    • The Aquasnap units are designed to offer 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.
    • Single or dual pump (option) with operating time balancing and automatic changeover to the back-up pump if a fault develops
    • Water filter protecting the water pump against circulating debris
    • Pressure transducers for direct numerical display of the water flow rate and water pressures
    • Thermal insulation and frost protection down to -20 °C, using an electric resistance heater (option)
    • High-capacity membrane expansion tank (option).
    • Integrated hydronic module with Greenspeed® variable speed pump (option)
    • Easy and fast electronic setting of the nominal water flow at unit commissioning thus eliminating the water flow control valve adjustment
    • Automatic control of the pump speed based on constant speed, constant pressure difference or constant temperature difference.
    • A single power supply point without neutral
    • Main disconnect switch with high trip capacity
    • 24 V control circuit without risk from a transformer included.
    • Fast unit commissioning with systematic factory test before shipment
    • Quick-test function for step-by-step verification of the instruments, electrical components and motor.

    Standard Warranty

    • One year from start-up or 18 months from shipment
