The 30RH Aquasnap heat pumps feature the latest techno-logical innovations: ecological refrigerant HFC-407C, scroll compressors, low-noise fans made of a composite material and microprocessor control. The refrigerant circuit with its patented receiver/heat exchanger, and the auto-adaptive Pro-Dialog control system guarantee reliable and economical operation in all climates from -10°C to 45°C. Aquasnap includes a complete hydronic module as stan-dard, simplifying the installation to straightforward opera-tions like connection of the power supply and the water supply and return piping.

Features

�

Integrated hydronic module for fast installation, incorporat-ing all hydronic components: removable screen filter, water pump with high available pressure, expansion tank, water flow switch, safety valve, pressure gauges, and purge valve. A throttle valve allows adjustment of the water flow in accordance with the characteristics of the installation. All components are protected against frost down to -20°C.

�

Low-volume water loop: the auto-adaptive algorithm con-trols the water temperature and eliminates any risk of excessive compressor cycling. In the majority of comfort air conditioning applications a buffer tank is unnecessary.The low water volume reduces the energy consumption during changeover from heating to cooling during in-between seasons.

�

Ecological refrigerant HFC-407C: no effect on the ozone layer, replaces R-22 in air conditioning applications with small and medium capacities. Extensively tested by Carrier for several years, it offers the same performance and relia-bility guarantees as R-22.

�

The receiver/heat exchanger (Carrier patent) enhances relia-bility and performance of the 30RH heat pump. In the heat-ing mode the refrigerant is condensed in the receiver at the plate heat exchanger outlet. This device compensates for large differences in volume between the coil and the water heat exchanger (plate heat exchanger). It ensures an ideal refrigerant charge in heating and cooling mode and perfect control of subcooling or superheating. Compressor life is increased (no risk of refrigerant migration into the compres-sor), and the use of the heat exchangers is maximised.

�

The revolutionary, low-noise, two-speed Flying Bird II fan is made of composite recyclable material and employs a multi-blade design and a rotating shroud, as used in the aeronautical industry. It is exceptionally quiet, and does not generate the low-frequency noise, irritating to the human ear. At part load or low outdoor temperatures the fan auto-matically switches to the low speed. To reduce the operat-ing noise even further, the fan is not fixed to the top unit panel, but supported by an extremely rigid tower chassis.

�

Defrost is optimised by the auto-adaptive algorithm. This and the new coil design reduce the defrost cycle duration by an average of 50%. For increased safety an electric heater prevents accumulation of ice on the air heat exchanger base.

Air-to-Water Heat Pumps with Integrated Hydronic Module

Carrier is participating in the Eurovent CertificationProgramme. Products are as listed in the EuroventDirectory of Certified Products.

�

Quiet, vibration-free scroll compressors, durable and maintenance-free. The use of several compressors per circuit (from size 30RH 050) reduces the start-up current and the power consumption at part load.

�

The refrigerant circuit is completely leak-proof for life. All pipes and refrigeration components are welded. Pressure sensors, mounted directly on the pipes, take the place of the pressure switches and their capillary tubes, a source of leaks in the past.

�

From size 30RH 090 upwards, two independent refrigerant circuits ensure partial cooling/heating capacity in all circumstances.

�

Electrical connections are simplified, and the standard Aquasnap equipment includes a main disconnect switch, and a single entry point of the three-phase without neutral power supply to the whole unit.

�

Large removable panels and the hinged door of the control box ensure perfect accessibility and permit easy access to all components. Furthermore an opening allows adjustments to be made without interrupting the operation of the unit. For the most important maintenance operations the unit top cover is easily removed, and total access from above is possible, with the fan remaining in place.

�

The electric resistance heater control module (accessory) permits control of up to four stages of electric heat for supplementary heating at low outdoor temperatures.

�

The evaporator is a welded, stainless steel plate heat exchanger, maximising the thermodynamic properties of HFC-407C and offering considerably increased performances as well as low water-side pressure drops.From size 30RA 090 upwards the units are equipped with a twin-circuit interlaced heat exchanger for safe operation at part load. When the unit is shut down, the heat exchanger is protected against freeze-up by a trace heater.

PRO-DIALOG Plus control

PRO-DIALOG Plus is an advanced numeric control system that combines complex intelligence with great operating simplicity. PRO-DIALOG Plus constantly monitors all machine parameters, optimising the operation of compressors, fans, cycle reversing valve and water pump.

A powerful control system

�

The Pro-Dialog Plus control is auto-adaptive and guarantees total protection of the compressors. The system permanently checks the operating parameters and responds to avoid excessive cycling and maintain the ideal operating range for the compressor (temperatures and pressures out of range etc.). By taking corrective action before the fault occurs, the auto-adaptive control frequently prevents a shutdown of the heat pump due to a fault condition.

�

To optimise power consumption, PRO-DIALOG Plus automatically resets the chilled water temperature set-point in accordance with the outdoor air temperature or the return water temperature or uses a second set-point (example occupied/unoccupied) and ensures automatic heating/cooling changeover.

�

The system also controls the start-up of a boiler relay or manages a supplementary electric heater (accessory).

Clear and easy-to-use control system

�

The operator interface is clear and user-friendly: LEDs and two numeric displays ensure immediate verification of all unit operating data.

�

Buttons conveniently positioned on a synoptic heat pump diagram offer immediate display of the operating parameters: temperatures, pressures, set point, run times etc.

�

10 menus offer direct access to all machine controls, including a history of possible faults, for rapid and complete heat pump fault diagnosis.

Extended communications capabilities

�

PRO-DIALOG Plus allows remote control. Volt-free contacts regulate: start/stop, cooling/heating mode selection, power demand limit or selection of the second set point. The system permits remote signalling of any possible anomaly for each refrigerant circuit.

�

The internal clock permits programming of:- heat pump start/stop- operation at the second set-point (e.g. unoccupied room)- operation of the chiller with the fan at low speed to

reduce the noise level.

�

Master/slave control of two chillers operating in parallel with operating time equalisation.

�

RS 485 serial port for remote chiller control via communications bus.

Part 2 - ProductsEquipment

Compressor� Hermetic scroll compressor with only three moving parts,

2-pole electric motor, cooled by suction gas with overload protection through an internal thermostat and/or thermal relay. Oil level sight glass and polyolester synthetic oil charge.

Water heat exchanger� Stainless steel plate heat exchanger with welded copper

connections; from size 30RH 090 upwards the water heat exchanger has interlaced independent refrigerant circuits.

� Closed-cell thermal foam insulation.Anti-freeze protection during operation by flow switch (standard on all versions) and during shutdown down to-20°C by electric resistance heater.

Air heat exchanger/fan� One (30RH 040-080) or two (30RH 090-240) vertical coils

with slotted aluminium fins expanded into grooved copper tubes. Coil protection grille made of steel wire, coated in polyethylene. Protection against ice build-up by electric resistance heater on the coil support.

� Low-noise axial Carrier Flying Bird fan with 11 blades and a rotating shroud, made of a composite material. Three-phase, two-speed motor (11.5/5.8 r/s or 15.6/7.8 r/s), insula-tion class F, protection category IP 55, overload protection by thermal relay. Vertical air flow with protection grille made of steel wire, coated in polyethylene.

Refrigerant circuit� Each circuit includes: a four-way cycle reversing valve,

liquid line valve, moisture sight glass, two-way expansion device, receiver/heat exchanger, protecting the compressor against refrigerant migration, removable suction line screen filter, high-pressure safety valve, pressure and temperature sensors, manually reset high pressure switch, and a refriger-ant charge of HFC-407C. All components of the refrigerant circuit are welded for total and lasting leak-tightness.

Control and power circuit control box� The control box is accessible via a hinged door. It includes

a main disconnect switch, fuses and circuit breakers, com-pressor, fan and water pump contactors, thermal relays, low-voltage control circuit transformer (24 V control cir-cuit) and the Pro-Dialog control system.

The whole unit is supplied by a single power connection point (three-phase supply without neutral).

Chassis/cabinet� Chassis and cabinet made of galvanised sheet steel. Painted

in oven-baked polyester powder paint in light grey colour (RAL 7035). Removable panels with 1/4 turn locks.

Hydronic module� Hydronic module, integrated into the heat pump, including:

removable screen filter, expansion tank, single monocell centrifugal water pump (dual water pump optional) - three-phase motor with internal thermal protection, water flow switch, safety valve (set to 3 bar for 30RH 040-160 and to 4 bar for 30RH 200-240 units), flow control valve, pressure gauge and purges. Internal piping made of galvanised steel. Customer-side Victaulic connections with welding or screw connection sleeves. Protection against ice build-up down to -20°C by thermal insulation and water pump cycling.

Note: Units without hydronic module (option): internal water piping protected against frost down to -10˚C by electric resistance heater.

Carrier Pro-Dialog Plus control systemPro-Dialog Plus ensures the following functions:

Control� Entering and leaving water temperature control by PID loop

with compressor run time equalising. The system perma-nently adjusts the system inertia and ensures complete pre-vention of excessive compressor cycling. The heat pump can safely operate with a low system water volume which often makes the use of a buffer tank unnecessary (see mini-mum water volume in this document).

� Head pressure control by auto-adaptive algorithm (fan speed).

� Water pump control (optional dual pump with automatic change-over).

� Defrost cycle control with auto-adaptation of the parame-ters.

� Control at the second set point (example: unoccupied room).

� Set point reset as a function of the air temperature or the difference between entering/leaving water temperature.

� Automatic change-over of heating/cooling, as a function of the outdoor temperature with adjustable dead band.

� Optional control module with a relay for the control of sup-plementary electric resistance heaters. Four stages maxi-mum, with start-up of the last stage in case of a heat pump shutdown as a result of a fault condition.

Safety� The system checks the evolution of the parameters: tempe-

ratures, pressures ... and responds to maintain the compres-sor within the operating range. If despite this one parame-ter exceeds its limit, an alert message is generated or the unit is shut down. The following faults cause the refrige-rant circuit or the unit to be shut down:- Low suction pressure- High discharge pressure- Low suction temperature- Low water entering temperature in heating mode- Compressor, water pump overload- Reverse compressor rotation- Temperature sensor and pressure transducer fault- Board and loss of communication fault- Customer safety device tripping- Heat exchanger anti-freeze protection- More than 50 alert or fault codes to facilitate fault detec-

tion

Operator interface� Includes status or fault LEDs, two numerical displays, a

refrigerant system synoptic diagram and a command key-board.

� Immediate display of parameters: entering/leaving water and ambient air temperatures, compressor suction/dis-charge pressures and temperatures, set point, operating temperatures and number of compressor start-ups.

� Diagnosis and complete parameter set by selection of one of the following menus: information, temperatures, pres-sures, set points, input values, test, configuration, alarms, alarm history and operating log.

Remote management of the heat pump� Volt-free contact inputs permit:

- Start/stop control- Selection of cooling or heating mode- Integration of a customer safety device- Operation at the second set point* (example room un-

occupied)- Maximum demand limit* (three limit levels from size

30RH 090 onwards)* One or the other for 30RH 040-080

� Outputs are available for:- Start-up of a boiler relay (shutdown of the heat pump

below a minimum outdoor temperature)- Signalling of a fault condition for each circuit.

� The internal clock permits programming of the following operations:- heat pump start/stop- control at the second set point (e.g. unoccupied room)- fan at low speed to reduce the noise level (e.g. during the

night)� Master/slave control of two heat pumps operating in

parallel with operating time equalisation.� RS 485 serial port for remote heat pump control via

communications bus.
