In caso di raffreddamento gratuito parziale i compressori

(13)sono attivati per assicurare il completo bilanciamento del carico ambiente.

In questo caso parte della miscela glicolata viene deviata dalle valvole pressostatiche (8) negli scambiatori (7) per effettuare la dissipazione del calore di condensazione.

Nel circuito frigorifero è inoltre inserito un sistema di iniezio- ne gas caldo (9) che evita formazioni di ghiaccio sulle batterie ad espansione diretta (2) durante il funzionamento combinato FREE COOLING + COMPRESSORI (escluso unità con compressori tandem).

Il gruppo di pompaggio esterno (4) è equipaggiato con un regolatore per il controllo della valvola miscelatrice (10) per evitare l'invio di soluzione glicolata a temperature troppo basse al sistema FREE COOLING.

Tali temperature produrrebbero una non necessaria deu- midificazione dell'aria trattata innescando un ciclo di deu- midificazione-umidificazione lesivo dell'efficienza energe- tica del sistema.

Il gruppo di pompaggio (4) può essere previsto con una sola pompa (11) o con due pompe, una in riserva dell'altra (modello /1 o /2).

Il serbatoio di carico (12) è fornito non installato.

Il dissipatore esterno (3) è disponibile in versione con ventilatore assiale (CVE/H) per installazione all'esterno o con ventilatore centrifugo (CVC/H) per installazione con mandata e/o ripresa dell'aria canalizzata.

Entrambe le soluzioni sono disponibili in versione standard e a ridotta emissione sonora (LN).

In case of partial free cooling, the compressor/s (13) are activated to assure the complete balance of room thermal loads.

In this case, the water regulating valves (8) diverts part of the glycol solution to the heat exchangers (7) to provide the total dissipation of the condensation heat.

Furthermore, each gas circuit is fitted with an hot gas injection system (9) to avoid freezing of the direct expan- sion coils (2) during mixed operation FREE COOLING + COMPRESSOR/S mode (excluded units with tandem compressors).

The remote pumping group (4) is designed for outdoor installation and it is equipped with a regulator, for the mixing valve (10) control, to prevents the insertion of glycol solu- tion at too low temperatures into the FREE COOLING.

As, too low temperatures will produce a no necessary dehumidification effect starting a dehumidification-humidi- fication cycle, detrimental to the system energy efficiency. The pumping group (4) can be supplied with one pump only

(11)or with two pumps, one as stand-by for the other (models /1 or /2).

The charge tank (12) is supplied not installed.

The external dry cooler dry cooler (3) is available with axial fans (CVE/H) or centrifugal fans (CVC/H).

Both are available in standard and low noise version (/LN).
