Dixell XWEB5000 Bedienungsanleitung PDF herunterladen (Seite 4)

Dixell has always considered energy saving extremely important, particularly now it is becoming crucial in

the refrigeration and conditioning ﬁeld. All regulators and systems have special algorithms allowing optimize

the efﬁciency of the system increasing the energy saving. Every user has their own requirements which can

be different from others, be it a compressor rack, a display case or a chiller. Dixell offers speciﬁc solutions

for every application…

ENERGY SAVING

The superheat controlling system, managed by Dixell series, allows

optimization of the plant performance using the “cold minimum quantity”

required. Nightly set back allows for different day/night temperature

sets points according to needs, whereas different/intelligent defrosts

provide the possibility of making those independently with selectable

time and limits. Also extremely important is the fan speed controller

to regulate fan speed depending on evaporator conditions and the

virtual probe that obtains the temperature from the real probes.

The compressor rack controller guarantees an excellent system efﬁciency by taking into account the

actual operative conditions, which is vital in achieving effective energy saving. By use of the dynamic set

point, the system automatically modiﬁes the suction or condensing temperature/pressure according to the

external ambient or the retail space temperature, so changing the refrigeration power depending on the real

thermodynamic exchange. It’s also important to make a check of heat recovery, of an accurate management

of the sub-cooling in order to increase the system and the inverter outputs efﬁciency that assure an uniform

check of the refrigeration power and its condensation.

COMPRESSOR RACKS

Optimization of chiller usage is synonymous with energy saving:

for this reason Dixell controllers are equipped with functions such

as dynamic set point to allow an automated modiﬁcation of the

working set point depending on the external temperature. Also a

reduced set point that takes advantage of the time bands concept,

it allows management of weekly start/stop in order to have this

function ON only if it is necessary.

The circuit balance regulation is achieved through the activation or

deactivation of the compressors to produce only the minimum refrigeration

power required at any given moment.
