LOGICA DI COMANDO APERTURA SER- RANDA FREE-COOLING ARIA ESTER- NA (unità ROOF TOP).

Il sistema MP 2000 controlla l’apertura delle serrande aria esterna tramite il segnale xY0, per effettuare "Free-cooling"” e/o il ricambio dell’aria.

Quando la temperatura dell’aria esterna è inferiore alla temperatura ambiente, ed è richiesto raffreddamento, vie- ne utilizzata l’aria esterna (più fresca) riducendo/evitando l’utilizzo dei compressori ottenendo così un notevole ri- sparmio energetico.

CONTROL LOGIC FOR OPENING THE EXTERNAL AIR FREE-COOLING DAMPER (ROOF TOP units).

The MP 2000 system controls the opening of the external air damper through signal xY0, for performing the "free- cooling" and/or for fresh air.

When the external air temperature is lower than the room temperature and cooling is requested, the external (fresh) air is used, to limit/avoid the use of compressors, as well as to save energy.

temperatura il valore si incrementa propor-

 

zionalmente.

xPe1

Valore di temperatura per il quale il segnale

 

proporzionale xY0 corrisponde al valore mas-

 

simo di raffreddamento, con la serranda aria

 

esterna tutta aperta (100%), a condizione

 

che sia possibile il free-cooling (vedi "Logica

Valore in percentuale (0⎟100%) di apertura della serranda, corrispondente alla quantità minima di aria esterna voluta.

Tutti i parametri sono riferiti direttamente o indiretta- mente al setpoint impostato.

proportionally to the rise in temperature.

xPe1

Cooling prop. Valve Max (1.5°C)

 

Temperature value for which the propor-

 

tional signal xY0 corresponds to the maxi-

 

mum cooling value with the external damper

 

completely open (100%), provided that Free-

 

cooling is possible (see "free-cooling ena-

Af – Setpoint fresh air (30%)

Opening value in % (0⎟100%) of the damper, corresponding to the minimum quantity of external air required.

All parameters refer directly or indirectly to the preset set point.
