Congratulations on your excellent choice in acquiring a system that will reduce your

energy consumption and benefit the environment.

Please read the manual carefully before installing your thermodynamic solar system.

This manual does not intend to replace, in any way, the thermodynamic solar systems

installation course.

ATTENTION

The use of a power circuit with inadequate voltage and frequency will result in the

damage of the unit and potentially cause a fire incident.

Pulling the power cable may cause damage or electric shock. Don't use the power

cable incorrectly.

Always use a fuse with the proper amperage.

As for the feeding cables, please comply with the local rules and regulations. The

improper connection may result in the overheating of the feeding cable, the connector

or the electric socket and cause a fire.

For your safety, turn off the circuit breaker or disconnect the power cable when you do

not intend to use the equipment for a long period of time.

In case the cable needs replacement, use only the network power cable specified by

the manufacturer.

Any and all intervention should be performed by a certified technician.

Any repairing or maintenance operation that is not performed by a certified technician

will result in the loss of warranty.

1.0Functioning



TheENERGIEsolarsystemsarethermodynamicsolarsystems.



Thesolarpanellocatedoutsideensuresthecaptureofenergythrough:



oDirectanddiffuseradiation

oExteriorairbynaturalconvection

oWindeffect(usuallypresent)

oRainwater



Thetemperaturegradientcausedbytheabovefactorsensuresthatthefluidpassestothe

gaseousstateinsidethepanel.



Thecompressorextractsthecoolingfluid(vapour)fromthepanelbyrisingitspressureand

temperature,whichisthentransmittedtothewatercircuitthroughaheatexchanger.



Theexchangerisplacedinsidethecabinet(ThermodynamicBlock)providingheattothewater

ithasinside.



Whenthecoolantreachestheexpansionvalveitisintheliquidphase,andthelossofloaddue

tostrangulationreducesthepressure,whichleavesthefluidreadytore‐enterthepanels.

recommended.



2.3FluidDistributor



Toensurethatthefluidreachesthepanelin

aseamlessmanner,it'snecessarytoinstalla

fluiddistributor.Thisdistributorfeaturesas

manydistributiontubesasthenumberof

panelsintheinstallation.



Thedistributorisplacedbetweenthepanels.



2.5Tubing



Itisessentialthatthetubinghavecoolingqualities,bothinthesuctionandinthefluidline

(feeding).Itisalsorecommendableforallthetubingtohaveahighqualitythermalisolationto

3.2Unevenness



Innormalsituationsthemaximumunevennessshouldalwaysbelessthan15meters.

However,therearesituationswhereitisnotpossibletorespectthatmeasurement.Insuch

casesyoupleasecontactourtechnicaldepartment.



Thesuctiontubingandthedistributionrodsshouldriseabovethepanellevel,inordertoavoid

theeffectofquicksiphonofthefluidwhenthecompressorstops.



3.3SolarPanelsOrientation



TheENERGIEsolarpanelsshallbe,

preferablyorientedtowardsSouth,but

theycanalsohaveadislocated

orientationtoNortheastorNorthwest.



3.4TiltAngle



Thetiltingangleofthesun

beamsinrelationtothe

horizontalpositiondependson

theseason.Inthewinter,in

Zenith,thesunbeamshavean

angleof20ºto40ºinrelationto

thehorizon.Inthesummer,the

angleisbetween60ºand80º.



Tobenefitthemostfromthesunbeamsitispreferabletochooseatiltbetween45ºand90º.
