4.5 FUNZIONALITÀ PRINCIPALI 4.5 MAIN LOGIC CONTROL
Dispositivo by pass per free cooling / heating (Fig. 4)
Le unità OTA1 sono provviste i sezione apposita interna i
bypass parziale el recuperatore, sul =usso i aria espulsa.
Quan o la temperatura esterna è prossima alla temperatura
interna si può ri urre sensibilmente lo scambio i calore
attraverso il recuperatore. La macchina viene fornita con
sistema i apertura manuale (stan ar ) o con servomotore
opzionale: la con<gurazione a utomatizzata p uò essere
coman ata attraverso un consenso esterno o alla gestione
elettronica integrata (opzionale)
Bypass device for free cooling / heating (Fig. 4)
OTA1 units are equippe with special internal section for the
bypass function on the exhaust air stream.
When the air intake temperature is near the air outlet
temperature the heat recovery unit can be partly bypasse
re ucing the heat exchange. The unit coul be equippe with
manual opening sysyem (stan ar ) or with optional electric
motor: the automate con<guration c an b e m anage b y an
external input or by integrate electronical management
(optional)
Fig.4
Sbrinamento (Fig. 5)
Nei perio i molto fre i l’aria i ripresa ambiente potrebbe
brinare ostruen o il passaggio attraverso il recuperatore.
Installan o l’accessorio RMS e l’accessorio SIGB/Q, è possibile
gestire lo sbrinamento el recuperatore. Se le son e i
temperatura esterna rilevano valori inferiori al set i
sbrinamento, le serran e “A” e “B” si chiu ono e si apre la
serran a “C”. In questo mo o l’aria cal a i ripresa ambiente
viene ricircolata consenten o un rapi o scongelamento el
recuperatore stesso che può successivamente tornare al
funzionamento normale.
Defrost (Fig. 5)
When the intake air is very col , frost may form on the heat
recovery unit. By installing the RMS accessory combine with
the SIGBQ option the heat recovery efrosting can be
controlle . When the out oor air temperature is lower than
the efrosting set, the ampers “A” an “B” will close an the
amper “C” will open. So the warm return air is recirculate ,
allowing the heat exchanger efrosting. Afterwar s the unit
functioning will become normal.
