The use of INVERTER systems together with refrigeration compressors is nowadays subject of several studies conducted both from
research institutes and refrigeration systems manufacturers worldwide leader in this field.
The main benefits arising from the use of an INVERTER coupled with compressors working into refrigeration units and in refrigeration
systems generally speaking, are:
energy savings since the system will absorb less energy,
increase in compressors reliability thanks to the significant decrease of compressors startups: a standard system stops when it has
reached the desired temperature and then suddenly re-start when this temperature increase again. INVERTER systems instead reduce
gently their refrigeration duty while approaching the desired temperature until they softly stop and then gently re-start while the
temperature increases again (theoretically the compressor can even never stop working, continuing to give the minimum duty that is
enough to keep the ambient constantly cold),
big reduction of the time by which the system runs in transient conditions, especially in terms of suct ion pressure. This can make the
installer able to design an evaporator with lower mean T between the ambient of the cold room and the refrigerant,
noise reduction also during the nights, thanks to the extremely high system flexibility.
In any case is strictly recommended the use of soft start inverter and we invite you to contact our technical department for the vibration
dampers specification.
APPLICATIONS
Supermarket refrigeration systems seem to be one of the best field of use for INVERTER applications.
For instance it has been recently led a comparison between the behavior and performances of a system running without INVERTER
first and then using such a device. The system was made of two different sub-systems; the first one for low temperature (called BT),
the second one for medium temperature (called TN), both equipped with DORIN compressors. Here follow the test results.I grafici e la tabella precedentemente esposti mostrano
inequivocabilmente come siano stati acquisiti i tre vantaggi
cui inizialmente si faceva riferimento, ovvero:
risparmio energetico
aumento dell’affidabilità dei compressori
diminuzione dei transitori dell’impianto
riduzione della rumorosità
Taking a look to those results it can be clearly
understood how the aforesaid advantages have been
achieved, that’s to say:
energy savings
compressors reliability increase
transient timeframes reductions
noise reduction
Les graphiques et le tableau figurant ci-dessus montrent
clairement comment ils ont acquis les trois avantages qui l'a
initialement visée, c'est-à-dire:
les économies d'énergie
l'augmentation de la fiabilité des compresseurs
la réduction des transitoires du système
la réduction du niveau sonore
