AIR FLOW

In the LEONARDO EVOLUTION conditioners, the air can flow upwards or downwards (UPFLOW / DOWNFLOW).

UPFLOW

Upflow units (with upwards air discharge) are designed to distribute the air through a system of ducts or by means of a falseceiling. Air intake is usually through the front of the unit, but versions are also available with air intake through the rear or thebase of the unit.

INTRODUCTION

Presentation of the system

The Leonardo Evolution precision air conditioners are designed for environments which are characterised by the presenceof highly technologically advanced equipment: telecomms and internet centres, data processing rooms and any type ofenvironment which is characterized by high concentrations of power.

The Leonardo Evolution series consists of 4 types of conditioners: Direct expansion

Chilled water Energy Saving Twin-Cool

DOWNFLOWDownflow units (with downwards air discharge) handle large volumes of air which are distributed uniformly into the environmentby means of a void under a raised access floor. The air enters the unit directly from the environment, or through a ventilatedor false ceiling.

AIR COOLED DIRECT EXPANSION UNITS (DXA)

The air cooled DX units extract heat from the room and transfer it tothe outside using air cooled refrigerant heat exchangers (condensers).The room unit and external condenser form an autonomous sealed circuitonce installed. The UNIFLAIR remote condensers used with LEONARDOunits include a precise electronic system to regulate the fan speed toensure trouble-free operation throughout the year under a wide range ofexternal air temperatures. Special attention has been paid to the acousticdesign of the condensers to minimise noise levels. A wide range of

combinations is available to meet different site requirements.

WATER COOLED DIRECT EXPANSION UNITS (DXW)

In the DX water cooled units, the heat extracted from the room istransferred to water via a stainless steel brazed plate exchanger withinthe unit.The cooling water may be fed from the mains supply, a cooling tower ora well (open circuit), or recycled in a closed loop cooled by externalcoolers.In the latter case, an anti-freeze mixture of water and ethylene glycol is

normally used.The water cooled units have the advantage that the refrigerant circuitsare charged and sealed in the factory. This makes installation extremelysimple, eliminating the need for any site-installed refrigerant pipework.

Connection to the drains

The condensed water drains from the tray through a siphonedflexible tube fitted in the unit.If the conditioner is fitted with a humidifier, the condensatedrain tray and the humidifier drain connection must beconnected to the drains of the building.Direct connection to the drains of the building

Connect the drainage tube of the unit to the drains of thebuilding using a rubber or plastic tube with an internal diameterof 25 mm.The external drainage tube must be siphoned in order to avoidunpleasant odours. Maintain a minimum slope of 1%downstream of the siphon.

Once the connections have been made, pour water into thecondensate drain until the siphon inside the unit is full.

The external drainage tube must be siphoned to avoidunpleasant odours and an overflow of the water from the trayof the humidifier. Maintain a minimum slope of 1% downstreamof the siphon.

Once the connections have been made, pour water into the

condensate collection tray of the Leonardo unit and in thecondensate collection tray of the humidifier until both siphonsare full.

Connection to the gas drain

The cooling circuit is equipped with a safety valve for thedischarge of the refrigerant gas.The intervention of the valve pressurises the discharge of therefrigerant fluid, possibly also to high temperatures; in thecase of installation in a closed environment, where there isthe risk of causing damage to people nearby, a conveyingtube must be used from the discharge to outside the room;this must be done in such a way that the operation of the

valve is not affected: it must not create a full flow, a counter-pressure higher than 10% of the pressure of the calibration.Where it is not possible to install a conveying tube it is goodpractice to create adequate aeration of the environment, andindicate, through specific signs, the presence of the drain.Also check that the discharge of the valve does not takeplace behind the electrical boards or electrical equipment.

Choosing the diameter of the discharge tube

The discharge line must be sized in such a way that it guarantees the flow of oil, in particular when operating at partial load,avoiding the return of the condensate refrigerant to the head of the compressor and prevent excessive vibration and noise

due to the pulsations of hot gas, vibrations of the compressor, or both.Even if it would be preferable to have low losses of the load along the line, an oversized discharge line is necessary toreduce the speed of the refrigerant so that it does not provoke a reduction in its speed and therefore reduce the flow of oil.Moreover, when the machine uses more compressors for the cooling circuit, the discharge line must transport the oil at alloperating levels.The minimum diameters needed to guarantee the flow of oil can be found in Graphics 1 -2 for the horizontal and vertical linesrespectively.In the installation of machines which have more compressors per circuit, the vertical discharge line, sized in order toguarantee the flow of oil at minimum load, may cause excessive loss of load when operating at its maximum level; in thiscase it is possible to use pipes with a larger diameter together with an oil separator.The loss of load along the discharge line causes an increase in the condensing temperature and therefore a decrease in thecooling capacity of the conditioner. Please note that each percentage point of decrease in the cooling capacity correspondsto a decrease of 1C of the maximum operating temperature. Normally the systems are sized in such a way that the loss

of load from the discharge line does not cause a decrease in the efficiency of the machine of more than -3%.The responsibility of establishing the refrigerant line between the condensing unit and the external unit lies

with the installer.

BACKFLOW LINE DIMENSIONING (LIQUID)To avoid gas development inside the line and to ensure anadequate pressure is reached inside the laminating unit, theliquid line must be correctly dimensioned. Generally, thesystems are dimensioned so that pressure loss along theline causes a variation of the saturation temperature between0,5 K and 1 K

During the installation of the cooling unit, a solenoid

valve should be fitted on the liquid line between theinner unit and the external condenser, to avoid

malfunctioning and to protect the compressor from

unwanted liquid migration during start- up.

Evacuation of the refrigeration circuit and charging of refrigerant

WARNING! The charging and maintenance of the refrigeration circuit must only be carried out by a

qualified hydraulic technician.

The refrigeration circuit is pre-charged with nitrogen.To load the refrigerant, carry out the following procedure:

R22

open any shut-off valves present in the machine to ensurethat all of the components will be evacuated;

connect a pump to empty the schrader connectionsefficiently, or to the 1/4" SAE connections present onthe intake and delivery sides of the compressors;

connect the refrigerant cylinder to the loadingconnections;

create a vacuum within the lines while maintaining thepressure below 100 Pa absolute (0,7 mm Hg) for a longtime in order to evacuate the air as well as any traces ofhumidity. It is preferable that the vacuum is reachedslowly and maintained for a long period of time;

wait for a build up period of 100 seconds and check thatthe pressure has not exceeded 200 Pa absolute.

Generally, in the case of suspicion of strong hydration ofthe circuit or an extremely extensive system, it will benecessary to break the vacuum with anhydrous nitrogenand then repeat the evacuation procedure as described;

break the vacuum by performing a preload from the R22coolant cylinder;

after having started the compressor, slowly complete theloading phase until the pressure within the lines has beenstabilised and the gaseous bubbles have disappearedfrom the flow sight glass;

the loading process must be controlled in environmentalconditions with a delivery pressure of approximately 18bar (equivalent to a saturated temperature of 48 C); in

the case of units with ON/OFF condensation controls,avoid switching the condenser fan on and off, which maypartially obstruct the intake surface. It is wise to checkthat the sub-cooling of the liquid at the entry of thethermostatic valve is between 3 and 5 C below thecondensation temperature read on the scale of thepressure gauge and that the overheating of the vapour atthe exit of the evaporator is equal to 5-8 C.

R407C - R410A

Connection for water cooled units

WARNING! The laying of the lines and hydraulic

connections must only be carried out by a

qualified plumber.

WARNING! The chilled water must contain a

percentage of ethylene glycol (of the passive

type, which is therefore not corros ive) according

to the minimal external temperature predicted

(see the table below).

If the water temperature falls to below the dew point of the airconditioner, isolate the piping with closed cell material (e.g.:Armaflex or equivalent) to avoid condensation; the isolationmust allow the accessibility of the valves and the three piecejoints. Seal the piping holes through the base of the conditionerto avoid a bypass of air.

WARNING! The water cooled pressure must not

be above 6 bar.

erutarepmetgnizeerF C4- C01- C71- C52- C73-

If the temperature of the chilled water is not checked it mayfall to under 25C, therefore it is necessary to use apressostatic valve (available as an optional) for eachcondenser; in this case the pressure of the supply must notbe less then 200 kPa (2 bar).

WARNING! Do not use chilled water with an

evaporating tower because the condensers will

quickly become encrusted with limescale.

The condenser must be connected to the chilled waterdistribution network, paying attention to the direction of thewater inlet and outlet.The condensers are supplied by water pumped in a closedcircuit and chilled by external refrigerators; check that thesection of piping and the characteristics of the circulationpump are suitable: an insufficient flow of water can have anegative effect on the capacity of the conditioner.The chilled water temperature must be checked to ensurethat it does not fall to below 25C, preferably according tothe plan indicated in the figure.The microprocessor control system is predisposed for

measuring the temperature of the water using probes (A)and modulating the servomotor of the valve (B) or by drivingthe fans (C) of the external refrigerators.

Maximum and minimum water temperatures

The maximum and minimum water temperatures for chilledwater circuits and for hot water re-heat circuits are: 5C 90C.The accepted maximum amount of ethylene glycol is 50%.

Setting the pressostatic valve (optional on

chilled water cooled models only)

The pressostatic valve, by controlling the water flow, preventsthe condensing pressure falling too low and at the same timeminimises water consumption. When necessary, set thepressostatic valve by turning the regulation knob (the pressureincreases when turning it clockwise) until the condensationpressure stabilizes to recommended* checking the pressurewith a gauge fitted to the pressure tapping of the compressordischarge valve.

Setting the air flow sensor

The FS differential pressure switch intervenes if the fan (orone of the fans) stops working.The factory set point of the FS differential pressure switch isat 0.5 mbar (= 50Pa).As the difference in pressure between the suction anddischarge of the fans depends on the air flow, it may benecessary to calibrate the instruments after installation,checking that the contact closes when the fans are in

operation.To set the FS pressure switch, carry out the following proce-dure: simulate a fan fault by stopping a fan; check that the

pressure switch intervenes; if the pressure switch does not intervene, gradually

increase the setting until the pressure switch switchesoff:- using an adjustment screw, set the differential pressureswitch on a scale (from 0.5 to 4.0 mbar - from 50 to 400Pa).

Setting the dirty fi lter sensors

The PFS differential pressure switch is set according to theloss of load dependent on the dirt inside the filters and the airflow.The PFS differential pressure switch must be set at 3 mbar(=300 Pa).To set the PFS pressure switch, carry out the following pro-cedure: gradually cover the surface of the air filter and check

that the pressure switch intervenes when the filter is about

50-60 % covered; if the pressure switch does not intervene, gradually lowerthe setting, if it cuts in too soon, increase the setting:- using a star screw driver turn the regulation screws ofthe pressure switch to the desired value.

Setting the regulation and safety devices

After starting up the unit, set the following set points (seethe microprocessor control manual): Room temperature (cooling and heating set point); Relative room humidity (humidification and

dehumidification set point); Dirty filter differential pressure switch: see paragraph

"Setting the dirty filter sensor".The settings of the safety devices must not be modified.

CW CHILLED WATER UNITS

The CW uses the availability of chilled water to control the room conditions.This version of LEONARDO has a relatively simple construction andgives outstanding reliability.

The microprocessor controls the modulating action of the 3 way (or op-tional 2 way) chilled water valve to give accurate control.Careful sizing of the heat exchanger coils allows a high sensible to totalcooling ratio under most operating conditions.
