COST OR RELIABILITY?

THE DILEMMA OF MODERN SYSTEM ENGINEERING APPLICATIONS

Air-conditioning systems in trade centres influence both the starting investment and monthly management costs, for the whole

of their working lives.

This theme is even more relevant in residential applications with centralised systems . Furthermore, maximum working

flexibility requirements should be added to that, in serving different users while avoiding wasting energy and thus, money.

Finally, there are several industrial applications which require chilled water as service fluid, process fluid or vector fluid for

operator comfort and for conserving goods and enabling cycles to function correctly.

Furthermore, in all these cases, the working reliability of the system is decisive.

THE HIGH EFFICIENCY HYDRONIC SYSTEMS ARE EXTREMELY VERSATILE, RELIABLE AND WIDESPREAD

CLIVET CHILLERS REDUCE CONSUMPTION

AND ARE COMPACT AND RELIABLE

Despite their apparently low costs, split, multi-split and VRF direct expansion systems have a lot of limits in these applications. For example, they require a separate system for primary air treatment. The pipes that contain the refrigerant cross the served rooms and therefore they are subject to restrictions and use limitations. They cannot operate in the freecooling mode, the high efficiency and convenient mode that allows energy savings. the hydronic systems are certainly more complete and versatile. They make it possible to adopt various types of terminals in the served environment, from fan coil units exposed or integrated in the furnishings, up to radiant or induction systems. They are also irreplaceable in the service and process industrial applications. The main component performances , like air-cooled liquid chiller, are checked and certificated by Eurovent.

With over twenty years of technological evolution, Clivet liquid

chillers and heat pumps represent the state of the art in

air-conditioning in residential, trade and industrial environments.

Their success is based on high energy efficiency, compactness

and management and maintenance simplicity, with wide versatility

in the choice of the most suitable model for the specific use.

ELFOEnergy LARGE2 TECHNOLOGY IS THE ENERGY REFERENCE POINT

FOR LIQUID CHILLERS

MAXIMUM EFFICIENCY IS ASSURED BETWEEN THE 25% AND THE 75% OF THE SYSTEM LOAD

For maximum loads taking place only for a few hours of functioning per year. The high efficiency at partial loads of ELFOEnergy LARGE2 makes it much more competitive and efficient than other solutions.

THE MODULAR SCROLL IS THE EXCELLENT SOLUTION FOR PARTIAL LOAD ELFOEnergy LARGE2 uses Scroll-type high-efficiency compressors, with optimized spirals. Main advantages are:

Compressors manufactured in large numbers at industrial level, with strict quality checks and highest reliability thanks to the elevated production volumes. With two different-sized compressors, in order to achive more adjustment steps. So it is possible to supply for usage only the energy that is actually require. Efficiency increases by over 50% when operating at partial loads, thanks to the larger heat exchange surfaces available.

The electronic expansion valve contributes to the excellent performance (EEV) it adapts rapidly and precisely to the actual load required for usage, and the high performance heat exchangers.

Example refers to a WSAT-XEE 352, EXCELLENCE. Version. External temperature equal to 35°C / 30°C / 25°C, respectively.

VERY HIGH HEAT EXCHANGE EFFICIENCY

Thanks to the external ELFOEnergy LARGE2 coils, equipped with wide frontal surfaces and reduced depth, the following is

obtained:

An improvement in the working temperature of the chiller circuit and, therefore, its efficiency, since the approach between the air temperature and the temperature of the chiller fluid inside the exchanger is reduced; A reduction in consumption by the fans, thanks to the reduced depth of the exchanger which decreases air flow renewal drops. Furthermore, the automatic fan speed control, supplied in series, minimises the air renewal air requirement to function correctly and therefore further reduces consumption; A decrease in the sound level, since greater surfaces enable slower air speed in the exchangers.

* EUROVENT (ESEER) supply times reference and ARI (IPLV) reference for

seasonal efficiency calculations.

COMPLETELY AUTOMATIC FUNCTIONING

The microprocessor controller manages functioning automatically in line with maximum

efficiency criteria, enables up to 6 units to be coordinated in a local network (Master-Slave

function) and includes numerous safety functions and the management of any alarms.

The interface terminal is equipped with a backlit graphic display and a multifunction access

keyboard. The multi-level menu is protected by passwords which are differentiated by different

user types. The daily / weekly clock programmer function is standard.

Thanks to its attractive design, the interface terminal can also be positioned inside the rooms

being serviced or in a special system control room.

ECOBREEZE ELECTRONICALLY-CONTROLLED FAN TECHNOLOGY

Using ECOBREEZE the external rotary electric motor is operated by a continuous magnetic

switching of the stator, induced by integrated electronic control. The advantages are:

70% increase in efficiency thanks to the brushless technology and the special electricity supply; Increase in the working life, thanks to the elimination of the brush wear;

Reduction in the electrical consumption by the system, thanks to a drastic reduction of the

inrush current for the fans obtained using the integrated ‗Soft start‘ function.

Note: ECOBREEZE is supplied as standard in the EXCELLENCE version

The external axial fans are equipped with an innovative Winglet blade profile with an integrated deflector, which is able to increase aerodynamic efficiency. This results in a 10% reduction in consumption. The average acoustic emission is 6 dB less then traditional fans.

ELFOEnergy LARGE2 TECHNOLOGY ENABLES

THE SYSTEM TO BE INDUSTRIALISED

ELFOEnergy LARGE2 can be supplied complete with system components which are often provided as external to units.

Thus reducing:

Design time: all the accessories are created to guarantee the best overall performance; Installation costs: the accessories which are already connected manually, electrically wired and individually checked are ready to start working immediately; Dimension: integration of system members into the unit reduces technical spaces and increases the space available for other uses. The slim line structure enables it to be positioned even on terraces or in external service corridors.

THE ON-BOARD PUMPS ARE VERSATILE, READY-FOR-USE AND RELIABLE

The various solutions available are:

Standard pump, with a wide range of available heads.

Standard pump with emergency pump. The on-board microprocessor balances its

working hours and in case of any breakdown signals the fault and automatically activates

the reserve pump.

HYDROPACK, the modular solution with two parallel pumps. Automatically reduces

water flow in critical conditions, avoiding blocks due to overloading and consequential

interventions by specialised technical personnel. It is very useful during start-up, during

re-start after a pause in working (e.g. a weekend) or after a long period of inactivity. In

case of any pump breakdowns, the unit continues to function with 60% of the nominal

flow.

FREE HOT WATER Condensation heat recovery:

Partial: recovers around 20% of the available heat (desuperheater);

Total: recovers 100% of available heat.

Free hot water production for :

Supplying hot-water coils for post-heating;

Producing domestic hot water (with the intermediate exchanger);

Other processes or operations.

IT EXPLOITS EXTERNAL AIR FOR COOLING WITHOUT ACTIVATING THE COMPRESSORS

In the FREE-COOLING configuration, as soon as the external conditions enable it, the unit is able to cool the liquid reducing

compressor functioning up to their complete withdrawal. This configuration is particularly useful in applications with a

high number of room loads, since it notably reduces unit energy consumption and compressor wear.

EVEN THE STORAGE TANK AND THE PRIMARY CIRCUIT CAN BE INTEGRATED ON-BOARD A connection to the secondary use circuit is all that's needed. In this way, the system results even more simple and reliable. The units are complete with rapid connections on the hydraulic side, which further reduces set-up times by eliminating pipe threading operations.

Furthermore, other system components are also available as accessories, such as hydraulic attachments reported on the external walls of the unit (as standard with pumps and/or storage tank) and the required water filter.

COOLING PERFORMANCE

VERSION: EXCELLENCE


INTERNAL EXCHANGER PRESSURE DROP

THE WATER FLOW RATE CAN BE CALCULATED WITH THE FOLLOWING FORMULA:

kWf = COOLING CAPACITY [kW] DT = TEMPERATURE DIFFERENCE BETWEEN

WATER INLET / OUTLET

Q [l/s] = kWf / (4,186 x DT)

THE AIR SIDE PRESSURE DROPS ARE RELATIVE TO THE MEDIUM AIR TEMPERATURE OF 7°C

Q = AIR FLOW [l/s] DP = PRESSURE DROP [kPa]

ADMISSIBLE WATER FLOW RATE

Qmin 3,2 3,6 3,9 3,9 4,4 4,4 4,9 5,5 6,1 [l/s]

Qmax 9,0 10,2 11,1 11,1 12,2 12,2 13,5 15,1 16,6 [l/s]

Min. (Qmin) and max. (Qmax) water flow-rates admissible for a correct unit operation.

To the internal exchanger pressure drops must be added the pressure drops of the steel mesh mechanical filter that must be placed on the water input line. It is a device compulsory for the correct unit operation, and it is available as Clivet option (see the HYDRONIC GROUP ACCESSORIES). If the mechanical filter is selected and installed by the Customer, it is forbidden the use of filters with the mesh pitch higher than 1,6 mm, because they can cause a bad unit operation and also its serious damaging.

ELFOENERGY LARGE2

Configuration which allows hot water production

free-of-charge during the cooling function, thanks to the

recovery of part of the condensation heat which would

otherwise be disposed of into the external heat source.

This configuration is also known as "desuperheating coil". It is

made up of brazed-plate exchanger in AISI 316 stainless steel

which is ideal for recovering around a quarter of the heating capacity of the unit (equal to the sum of the cooling capacity and the absorbed power input of the compressors).

The partial recovery device is considered to be working when it is supplied by the flow of water to be heated. This condition improves the unit performance, since it reduces the condensation temperature: in nominal conditions, the cooling capacity increases indicatively by 3,2% and the absorbed power input from the compressors is reduced by 3,6%.

When the temperature of the water to be heated is particularly

low, it is opportune to insert a flow regulation valve in the

hydraulic circuit, to maintain the recovery output temperature

at higher than 35°C and thus avoid refrigerant condensation in

the partial energy recovery device.

B - WATER LOW TEMPERATURE

Configuration also known as "Brine". Enables a non-freezable solution to be cooled (for instance, water and ethylene glycol in appropriate quantities) up to a temperature of between +4°C and –7°C.

Includes:

- Appropriate exchangers, complete with thick closed-cell insulation;

- Electronic-type expansion valve, functional calibration and safety devices adapted to the particulars of use.

In the selection phase, it is necessary to indicate the type of function required, and the unit will be optimised with:

- Unit with single working set-point (only at low temperature)

- Unit with double working set-point.

The unit in this configuration have a different operation field, indicated on the previous pages.

In the low temperature operation, some partialisation degrees could be not available. For more information, contact our Sales Department.

Consult the appropriate table, shown in the final section, to verify the compatibility between the different options.

ELFOENERGY LARGE2

Configuration which allows hot water production free-of-charge during the cooling function, thanks to the total recovery of the

condensation heat which would otherwise be discharge into the external heat source. This solution increases the overall

efficiency of the system in all cases in which a high-level of hot water production is requested.

It is made up of 316 Stainless steel brazed plate heat exchanger, which is ideal for recovering the entire unit heating capacity

(equal to the sum of the cooling capacity and the absorbed power input of the compressors), from the on-of type solenoid

valves, the temperature sensors for the hot water circuit supply and return and the relative integrated logic controller with two

partialisation steps.

La disponibilità di acqua calda è sempre subordinata alla produzione di acqua refrigerata. Si veda il seguente esempio:

1. Cooling capacity request = 100% / Heat capacity request = 0%→ Cooling capacity production only.

2. Cooling capacity request = 100% / Heat capacity request = 100%→ Cooling capacity production and heat capacity

production by recovery.

3. Cooling capacity request = 50% / Heat capacity request = 100%→ Cooling capacity production and heat capacity

production by recovery, equals 50% of the requested heat capacity.

R - TOTAL ENERGY RECOVERY

INTERNAL EXCHANGER PRESSURE DROP - TOTAL RECOVERY ENERGY

To avoid constant switching in the cooling circuit should be added to a adequate capacity storage tank in the hot water circuit of the system.

TOTAL ENERGY RECOVERY NOT OPERATING

When the set-point recovery is fulfilled, the coil is reactivated. In this condition the total recovery circuit operates as a partial recovery (desuperheater).

TOTAL ENERGY RECOVERY OPERATING

When hot water is required, the condensing coil is turned off. The condensation takes place entirely in the recovery circuit.

When the external air temperature is less than the temperature of the return water in the system, the FREE-COOLING system recovers coolness from outdoor and reduces the compressor working up to their being withdrawn completely.

The higher the temperature of the chilled water in the system (e.g. 10-15°C instead of 7-12°C), the greater the field of application of the FREE-COOLING system and, therefore, the energy saving.

USING UNFREEZABLE SOLUTIONS

The FREE-COOLING configuration is particularly indicated in buildings where, at least at certain times of the year, the external air

temperature also reaches very low values. For this reason, the liquid must be protected from the risk of freezing, typically by adding

an appropriate anti-freeze substance such as ethylene glycol. The percentage of glycol in the solution depends on the minimum

temperature value foreseen in the installation area, and in any case, remains within the main parameters of the system design.

TECHNICAL DESCRIPTION

In comparison with standard units, Clivet units in the direct FREE-COOLING configuration also include:

three-way switching valve with on/off regulation Finned water-air COIL exchanger (FREE-COOLING coil) additional outdoor air temperature sensor and control logic dedicated flush hydraulic connections.

(A) SUMMER SEASON

In the summer, with external air temperatures greater than the return temperature of the system liquid, the three-way valve is switched in such a way as to exclude the FREE-COOLING coils.

The cooling of the liquid is referred to the direct expansion circuit, via the workings of the compressors as in a traditional chiller.

(B) INTERMEDIATE SEASON During the intermediate season, or rather when the external air temperature is a little less than the temperature of the return water in the system, when the system senses that the external air temperature conditions are favourable:

it switches the position of the three-way valve forcing the solution to transit through the FREE-COOLING coils before reaching the evaporator;

it puts the fans to their maximum speed to exploit as much as possible the solution cooling using the outdoor air ; it undertakes the initial cooling of the solution in a "natural and free" way; it supplies any missing capacity through the chiller cycle, using the compressors functioning partially (the absorbed power input is proportional to the level of partialisation).

In case of an increase in the external air temperature, the microprocessor automatically converts the unit functioning to the summer setting, guaranteeing the conditions requested by the user at all times.

(C) WINTER SEASON During the winter season, with the temperature of the external air lower than the temperature of the return water in the system, the system senses that conditions are favourable for the FREE-COOLING function:

the three-way valve is switched as in the previous case, forcing the solution to transit through the FREE-COOLING coils before reaching the evaporator; the external air temperature brings the solution to the FREE-COOLING coil output already at the temperature requested by the user; the microprocessor management totally deactivates all the compressors supplying all the requested cooling capacity AT NO COST, in contrast to traditional chillers.

The difference between the outdoor air temperature and that requested by the user can also be such as to lower the solution temperature at the FREE-COOLING coil output to below the set-point requested for this use. This is a condition which does not compromise unit safety thanks to the presence of anti-freeze in the solution. The microprocessor modulates the fan speed until their withdrawal. If, with all the fans switched off, the temperature continues to go down, the three-way valve automatically positions itself in the summer setting, thus enabling the set-point to be maintained.

OPERATING MODE: DEACTIVATED DIRECT FREE-COOLING

To consider the standard unit performance at the requested conditions and apply the following correction factors.

EXAMPLE Determine the performance of the following units : WSAT-XEE FCD 702 SC EXC (EXCELLENCE version, direct FREE-COOLING configuration), with water = 15/10 °C / 30% glycol / Outdoor air 35°C Reference:

WSAT-XEE S 702 SC EXC Cooling capacity = 214,8 kW / Electric compressor capacity = 56,9 kW

Calculation:

WSAT-XEE FCD 702 SC EXC (Direct FREE-COOLING) Cooling capacity = 214,8 x 0,95 = 204,1 kW / Electric compressor capacity = 56,9 x 1,03 = 58,6 kW

OPERATING MODE: ACTIVATED DIRECT FREE-COOLING

When the outside air temperature increases, the cooling capacity of FREE-COOLING decreases (at the same temperature of water on returning from). If you know the cooling capacity required by the system, you can calculate the maximum outside air temperature from which the cooling capacity is available through FREE-COOLING. Below this temperature, the required power is supplied only by modulation of the air flow fans.

EXAMPLE Determine the performances with outdoor air = +1°C for the following unit: WSAT-XEE FCD 702 SC EXC, EXCELLENCE version, Direct FREE-COOLING configuration), with water at 15/10 °C / 30% glycol. Reference:

WSAT-XEE FCD 702 SC EXC FREE-COOLING nominal capacity = 204 kW (from table - Water 15/10 ° C / 30% glycol / outdoor air temperature 0 ° C) Calculation: Approach between the system outlet water temperature and the outdoor air = 15°C - 1°C = 14°C

From the graph: FREE-COOLING percentage = 93% FREE-COOLING capacity at +1°C of outdoor temperature = 204 x 93% = 189,7 kW

This option is necessary for very hot climates, where the external temperature can be between +40°C and +50°C. It is made up of a forced ventilation system, activated by a thermostat, which provides for the correct usage temperature to be maintained by the components inside the electrical panel. The option includes a thermostat which activates forced ventilation when necessary.

In order to guarantee that the correct unit operation, the temperature inside the unit must not exceed 50°C. Therefore, during storage or when the unit is already installed but not powered, it is necessary to avoid exceeding the above-indicated temperature. When the unit has been installed, the protection and safety devices are only active with the power supply switched on and the unit not isolated.

This accessory functions at all times even when the unit is switched off as long as the electricity supply is maintained and the unit is not isolated.

This accessory is necessary for the correct unit operation in the FCD (FREE-COOLING) configuration with external temperatures below –10°C. Furthermore, it is necessary for the units to be maintained correctly in all the remaining configurations (not functioning).


PM - PHASE MONITOR

The phase monitor makes it possible to check the correct connection of the phases and their imbalance in units powered with a tri-phase system. If the connection of the phases is not correct, or the threshold of phase imbalance is exceeded, or the voltage is too high or too low for a certain amount of time, the monitor acts on the control circuit and orders the unit to be shut down. As soon as nominal line conditions are restored, the unit is automatically reset. As soon as nominal line conditions are restored, the unit reset is manual.

PFCP - POWER FACTOR CORRECTION CAPACITORS

The component is necessary to lower the phase difference between current and voltage in the electromagnetic components of the machine, such as asynchronous motors. By re-phasing it is possible to reduce the intensity of the line current by reducing a part of the power of the mains (reactive power). This often leads to an economic benefit which the energy provider grants to the final user. The component makes it possible to bring the cosfi power factor to values which on average are greater than 0.9.


Option also known as 'Soft starter'. Electronic device that automatically and gradually starts the compressors reducing the start-up current of about 40% in comparison with the nominal value. It follows that the electrical power and its protective devices can be sized with lower parameters , so with a lower cost of initial investment.
