Hydraulic module

The AQUACIATGRAND INVERTER IVDC series packaged water chillers or heaters are medium-capacity units specifically designed for heating and air conditioning applications in Offices, Healthcare, Administration, Shopping Centres and the Residential sector.

These standard packaged units are designed for outdoor installation and require no special protection against adverse weather conditions.

To operate in HEATING or COOLING mode, they use the outdoor air as the only external source; this permits the evacuation of heat in summer or the supply of thermal energy for heating in winter.

Connected to an underfloor heating or cooling system, fan coil units or an air handling unit, the reversible AQUACIATGRAND

INVERTER IVDC series is an extremely easy way to heat and air condition buildings.

Each unit is delivered fully assembled, wired (control and power), charged with refrigerant and factory tested.

Simply make the necessary electrical and hydraulic connections, and your unit is ready to operate.

InVeRTeR Technology

The best technology at the heart of the AQUACIATGRAND INVERTER

While a traditional heat pump (HP) is equipped with an on/off type compressor, which can only adapt to the fluctuating requirements of an installation by running start and stop cycles, creating high amplitude fluctuations in the temperature of the water supplied to the system, AQUACIATGRAND INVERTER has all the benefits of a compressor with Inverter technology.

As power is able to vary constantly from 30% to 100% of the capacity, the AQUACIATGRAND INVERTER can adapt the consumption precisely, in accordance with the requirements of the installation which change in relation to the climate conditions.

This ability to adapt continuously is all the more important when we consider that for 95% of the time the installation is being used, its requirements will actually be below the rated capacity of the unit

AQUACIATGRAND INVERTER

Faster warm-up for quicker comfort

Stable and comfortable operation The on/off cycles of a traditional heat pump cause all of the thermal and thermodynamic variables to fluctuate, resulting in a longer warm-up time.Thanks to Inverter technology, the maximum power is supplied quickly; the AQUACIATGRAND INVERTER gradually adapts to meet requirements.As a result, operation remains stable, without any fluctuations in temperature, ensuring a stable level of comfort reached 20% more quickly.

Reduction in energy consumption and protection of the environment thanks to efficient energy performanceBy adapting proportionally and instantaneously to the requirements of the installation, the AQUACIATGRAND INVERTER does not have to run the compressor at 100% when the requirement is lower, as is the case with a traditional heat pump.

By limiting the power lost by running the compressor, the power consumed is therefore limited to a strict minimum - which can generate savings on your energy bill of up to 26% - compared to a «classic» heating system, giving a fast return on your investment.

Also, while a traditional heat pump operates intermittently with minimum stopping times (short-cycle protection) which requires a storage tank to be fitted, subsequently representing an additional cost and causing heat loss, the AQUACIATGRAND INVERTER instantly supplies the power required to the installation and a storage tank is no longer needed.

It takes up more than 35% less floor space.

The AQUACIATGRAND INVERTER ensures it can be as efficient as possible by reducing the standby power that the installation inevitably uses when the unit is not running.

Inverter Heat pump


Fan speed control: Unrivalled acoustic comfortA traditional heat pump is equipped with an on/off type fan which, each time it is activated, regularly creates peaks in the sound level which are particularly unpleasant for the surrounding neighbourhood.With the AQUACIATGRAND INVERTER the fan is of the Inverter type, as is the compressor, and its rotational speed automatically and easily adapts to the climate conditions and to the compressor speeds.Throughout a full season, a heating and cooling installation runs below its full load for more than 95% of the time.With the AQUACIATGRAND INVERTER and its DC motor fan, the sound produced by the installation is therefore instantly reduced to the lowest possible level for 95% of the time.

Electronic Expansion Valve: Energy efficiency & stability.The AQUACIATGRAND INVERTER is equipped as standard with an electronic expansion valve, which allows the cooling circuit to adapt quickly and continuously to changes in the compressor capacity.The constant adaptation of superheating, regardless of the unit’s operating speed, at full load and, most importantly, at partial load, increases its energy efficiency as compared to a traditional thermostatic expansion valve. This reactivity and the sensitivity of the electronic expansion valve allow the amplitude of the fluctuations for values such as low pressure, high pressure, and most importantly water regulation temperature, to be reduced by two thirds.


SOFT STARTER limiting disruptions of the electrical networkA traditional heat pump is generally fitted with an on/off type compressor, and as a rule the only way that this can obtain the power required is by running start and stop cycles.This leads to numerous start-ups, each of which requires a significant current (start-up current) causing regular disruptions to the electrical network.The AQUACIATGRAND INVERTER, on the other hand, has a gradual electronic start-up which limits its in-rush current and its starting current is therefore lower than its rated current under full load!

Inverter Heat pump

Most central air conditioning systems installed in the tertiary sector in Europe use water chillers to provide cooling.

Until today, the efficiency of air conditioners in Europe was measured using a single nominal test point under full load, called the Energy Efficiency Ratio (EER). However, a unit’s efficiency depends on its operating conditions.

Analyses of installed systems show that heat load varies from season to season and that a water chiller operates at reduced capacity for the majority of the time.

The European Seasonal Energy Efficiency Ratio (ESEER) measures the seasonal efficiency of water chillers by taking into account their efficiency under partial load using formulas created by the European certification body EUROVENT.

The efficiency under partial load is therefore essential when choosing a water chiller.

It is with this in mind that the new AQUACIATGRAND INVERTER range was designed, especially as regards the choice of R410A refrigerant which, thanks to its extremely high thermodynamic performance, makes much higher EER and ESEER ratings possible compared to R407C, and reduces electricity consumption by as much as 25%.

Thanks to its modulating compressor, the AQUACIATGRAND INVERTER can easily and efficiently adapt the cooling capacity to the installation’s requirements. The self-adjusting CONNECT control anticipates variations in load and adapts the compressor capacity to precise requirements. The compressor operates at optimum performance, energy efficiency is extremely high all year-round and, as a result, the system remains energy efficient for most of its life.

mInImUm waTeR VolUme (coolIng moDe)The Connect controller uses anticipation logic making it particularly flexible in adjusting operation to changes in settings, particularly on low-volume hydraulic systems.

By adjusting compressor running times, it prevents short-cycle protection cycles from starting and, in most cases, does away with the need for a buffer tank.

The calculation of the minimum water volume is given for EUROVENT rated conditions, in cooling mode only.

This value is applicable for most air conditioning applications (assembly with fan coil units)

Note: for installations running with a low volume of water (assembly with air handling unit) or for industrial processes, the buffer tank is a required component.

For heat pump applications, we recommend the use of a buffer tank to ensure a stable temperature is maintained during the defrosting cycles.

Precautions for installation

On-site installation of a unit fitted with the XTRAFAN option demands that some safety measures be taken, particularly if it is installed in a machine room.

This is the case for the discharge of condensates specific to reversible packaged units, including during periods of very low outdoor temperatures.

During defrosting cycles, reversible units are liable to discharge a large amount of water onto the ground, which must be drained, as well as steam from the fan discharge which can damage the air discharge ducts.

The ground upon which the unit is placed must be perfectly watertight and capable of collecting and draining the defrosted water, including during freezing periods. It is recommended that the unit be raised by approximately 300 mm.

When installed on a worksite with an air discharge duct, the weight of the duct must not, under any circumstance, be supported by the roof of the AQUACIATGRAND INVERTER; it is recommended that a flexible air discharge sleeve, supplied as an option, be used to connect it to the unit.

xTRafan VenTIlaTIonAquaCiatGRAND INVERTER units are equipped as standard with XTRAFAN ventilation.

This type of fan motor with electronic switching of poles and rotors with permanent magnets differs from standard motors fitted with a classic variable frequency drive by its excellent mechanical efficiency and by an exceptionally low sound level, whatever the load on the shaft.

Functions

The XTRAFAN offers a wide range of functions, making a whole host of flexible installation conditions possible, such as:

n the option of installation in a confined space, for example on a terrace surrounded by walls, where only an air supply with static pressure of between 125 and 200 pascals within a duct makes use possible without recycling or mixing of air at the condenser intake,

n installation in an urban area in which noise is a particular issue, where operation is only possible by adapting a sound trap to the supply air,

n the continued guarantee of operation during high temperature peaks for Middle Eastern type climates, thanks to the high temperature configuration of the condenser fan,

n a self-adjusting variable speed function which allows «all season» cooling, fully secured for industrial processes, including during harsh winter conditions with an external temperature of -20°C,

n the freedom to adjust with precision the fan speed on-site to what is «strictly necessary» to obtain the optimum air supply pressure, or the maximum acceptable sound limit for the site on which the unit is located,

n an improvement in the EER and electrical consumption for the unit in Cooling mode, in direct proportion to the refrigerant charge required by the installation.

Technical specifications and operating limits

XTRAFAN allows the user to choose any one of three configurations for use:

n increased use of the water chiller, with a high temperature configuration of fans with unimpeded air flow, so as to extend the exterior temperature range under full load from +46 to +50°C,

n obtaining an intermediate available static pressure of 125 to 150 Pa at nominal flow, which allows air to be discharged into a duct at the condenser outlet so as to ensure the fan does not recycle used air,

n obtaining a maximum static pressure for air discharge of 160 to 200 Pa, depending on the model, at minimum flow, recommended for on-site installation with a sound trap at the air discharge.

DegIpac IVDc DefRosTIng sysTem

DEGIPAC defrosting principleThis system, available as standard on CIAT CONNECT PLCs, allows an air-to-water heat pump coil to be defrosted at the most appropriate moment.By regularly scanning several reference parameters which evaluates the freezing level, such as the fluid evaporation temperature and that of the outdoor air, DEGIPAC only triggers defrosting when it is deemed necessary, and precisely determines the time required to defrost the fins of the heat exchanger completely.Compared to a traditional defrosting cycle with a timer, DEGIPAC can offer on average a 5% improvement of the seasonal COP and halves the season’s number of defrosting sequences.This improves the reliability of the heat pumps and ensures the frequency of the cycles is fully optimised, giving priority to cold and humid periods.

managemenT of backUp heaTIng DeVIcesA backup heating system may be used in addition to a reversible AQUACIATGRAND INVERTER depending on the change in the outdoor temperature and the heating requirements in winter.Three functions are therefore possible in HEATING mode:- thermodynamic heating alone (heat pump),- thermodynamic heating with additional elements,- electric water heating with all elements.These backup heaters can be supplied externally, or supplied by CIAT, such as the loop heater or the ME electrical backup heater modules, up to a maximum limit of 4 power stages.

elecTRIcal backUp heaTeR managemenT boaRD (150V To 200V)The electrical backup heater management board is an option which allows a reversible AquaciatGRAND INVERTER unit to manage 4 additional power stages in HEATING mode.Depending on the size or version of the units, this board is either a kit which is supplied separately, or a pre-fitted option made to order (please contact us).

DesUpeRheaTeR heaT exchangeRFree, additional hot water is produced by directly recovering the heat from gases released by the compressors by using a type of heat exchanger, called a desuperheater, fitted to the unit.

On reversible units, the desuperheater option can be used in both heating and cooling modes.

This optional configuration requires assembly in our factories and is by order only.

n Refrigeration circuit diagram

The refrigeration circuit diagram attached shows an example of a reversible unit fitted with a desuperheater.

Heat recovery is only possible when the unit is in operation in either COOLING or HEATING mode.

For the same cooling or heating capacity, the desuperheater provides a source of free hot water and lowers the unit’s electrical power consumption.

n Hydraulic connections: configuration and precautions

To ensure that the unit is commissioned and operates under the right conditions, the desuperheater water loop must be as short as possible. This will ensure that warm-up is gradual with a water flow rate of 10% its nominal value and that the nominal flow rate of the return water at the desuperheater inlet is +50°C.

A hydraulic circuit which allows superheated water in the desuperheater to be produced very quickly (three-way valve + thermostat + sensor on desuperheater water inlet) is therefore recommended

The thermostat setpoint must be at least +50°C.

Note: special attention should be paid when selecting the expansion vessel as the temperature of the recovery water circuit can reach 120°C if the accelerator pump is turned off or if no hot water is consumed.

Installation recommendationsn Water quality criteria to be respected

Important: it is essential that an 800 micron water filter be placed on the unit’s water inlet during installation.

The quality of the water used has a direct impact on the correct operation of the unit and its service life. This is particularly true if the water used clogs or corrodes components or promotes the growth of algae or microorganisms.

The water must be tested to determine whether it is suitable for the unit and whether chemical treatment will suffice to make it of acceptable quality and if a water softening/demineralising system should be installed.

The results of the analysis must confirm whether the site’s water is compatible with the various materials used on the CIAT unit’s circuit:

- 99.9% copper tubes brazed with copper and silver,

- threaded bronze couplings or flat steel flanges, depending on the unit model,

- plate heat exchangers and connections made of AISI 316/ DIN 1.4401 stainless steel brazed with copper and silver.

N.B.: The guarantee shall be void if these instructions are not followed.

n Lifting and handling

The utmost safety precautions must be taken when lifting and handling the unit.

Always follow the lifting diagram on the unit and in the installation, operation, commissioning and maintenance manual.

Before attempting to lift the unit, make sure the path leading to its intended location is free from obstacles.

Always keep the unit vertical when moving it. Never tip it or lie it on its side.

n Choosing a location for the unitThe standard version of the AQUACIATGRAND INVERTER is designed for outdoor installation.

Precautions should be taken to protect it from freezing temperatures.

Special attention should be paid to ensure sufficient free space (including at the top) to allow maintenance.

The unit must be placed on a perfectly level, fireproof surface strong enough to support it once charged.

Noise pollution from auxiliary equipment such as pumps should be studied thoroughly.

Potential noise transmission routes should be studied, with assistance from an acoustical engineer if necessary, before installing the unit.

Flexible couplings must be placed over pipes (available as options).

Reversible units installed in areas of snowfall or heavy frost should be raised approx. 300 mm off the floor or ground.

On reversible units, the steam and defrosted water must be properly evacuated during defrosting cycles.

n Installation in a machine roomInstallation in a machine room, if required, gives rise to special technical precautions, such as:- the draining of defrosted water, including during periods of very low outdoor temperatures,- the management of water vapour created at the fan discharge during defrosting- ground which can support the weight of the unit and which must be perfectly watertight and capable of collecting and draining the defrosted water, including during freezing periods,- the weight of an air discharge sleeve must not be supported by the roof of the unit, under any circumstances.According to the regulations in force where the installation is taking place, installation within a machine room may have to comply with certain ventilation rules for fresh air to ensure there is no risk of discomfort or any hazard in the event of a refrigerant leak.

Inverter Heat pump

n Assembly of separately supplied accessories:A number of optional accessories may be delivered separately and installed on the unit at its location.

Always follow the instructions in the installation, operation,

commissioning and maintenance manual

n Electrical connections:Always follow the instructions in the installation, operation, commissioning and maintenance manual.

All information concerning electrical connections is stated on the wiring diagrams provided with the unit. Always follow this information.

Electrical connections must be made in accordance with best current practices and applicable standards and regulations.

Electrical connections to be made on site:

. unit’s electrical supply,

. outdoor operation authorisation (optional)

. information feedback (option)

It should be noted that the unit’s electrical system is not protected against lightning strikes.

Therefore components to protect against transient voltage surges must be installed on the system and inside the electrical supply unit.

n Pipe connections:Always follow the instructions in the installation, operation, commissioning and maintenance manual.

All pipes must be correctly aligned and slope toward the system’s drain valve.

Pipes must be installed to allow sufficient access to the panels and fitted with heat insulation.

Pipe mountings and clamps must be separate to avoid vibrations and placing pressure on the unit.

Water shut-off and control valves must be fitted when the unit is installed.

- Pipe connections to be made on site:

. system water supply with pressure-reducing valve,

. evaporator, condenser and drain,

- The following are a few examples of accessories essential to any hydraulic system and which must also be installed:

. thermostatically controlled valve on the condenser water outlet to regulate the flow of cooling water (heat pump in HEATING mode).

. water expansion vessel,

. drain nozzles at pipe low points,

. exchanger shut-off valves equipped with filters,

. air vents at pipe high points,

. check the system’s water capacity (install a buffer water tank if necessary),

. flexible couplings on exchanger inlets and outlets,

. manual water flow rate control valves,

. thermometers on each water inlet and outlet to allow all the necessary checks during start-up and maintenance.

N.B.:

- Pressure in the water circuits below 4 bar.

- Place the expansion vessel before the pump.

- Do not place any valves on the expansion vessel.

- Make sure the water circulation pumps are placed directly at the exchanger inlets.

- Make sure the pressure of the water drawn in by the circulation pumps is greater than or equal to the required minimum NPSH, particularly if the water circuits are open.

- Test the water quality in accordance with the relevant technical requirements.

- Take the necessary precautions to protect the unit and hydraulic system from freezing temperatures (eg. allow for the possibility of draining the unit). If glycol is added to prevent freezing, check its type and concentration before commissioning.

- Before making any final hydraulic connections, flush the pipes with clean water to remove any debris.

n CommissioningAQUACIATGRAND INVERTER units must be commissioned by CIAT or a CIAT-approved contractor.

IMPORTANT: Following commissioning and every time the compressor has been switched off for a prolonged period (except during operating cycles), the unit must be switched on for 12 hours before start-up to ensure the compressor oil is correctly preheated.

Always follow the instructions in the installation, operation, commissioning and maintenance manual.

Partial list of precommissioning checks:

- Correct positioning of unit,

- Power supply protections,

- Phases and direction of rotation,

- Wiring connections on unit,

- Direction of water flow in unit,

- Cleanliness of water circuit,

- Adjusting water flow rate to specified value,

- Pressure in the refrigeration circuit,

- Direction of rotation of compressors,

- Water pressure drops and flow rates,

- Operating readings.

n Maintenance operationsSpecific preventive maintenance operations must be regularly carried out on the unit by CIAT-approved firms.

The operating parameters are read and noted on a «CHECK LIST» form to be returned to CIAT.

It is essential to comply with the Instructions, Installation, Operation, Commissioning and Maintenance Manual.

You must take out a maintenance contract with a CIAT-approved refrigeration equipment specialist. Such a contract is required even during the warranty period.
