Controlli elettronici OIO

ORIGINAL INNOVATION OPPORTUNITIES


REFRIGERAZIONE INTEGRATA
I controlli Elettronici OIO sono progettati per integrarsi con i compressori del nostro partner Wanbao. Ottimizzano il consumo e il funzionamento del sitema frigorifero e sono dedicati alle applicazioni della refrigerazione commerciale e professionale (banchi frigo, bottle coolers, spillatrici, etc.)

Il monitoraggio puntuale di tutti gli elementi previene il blocco della refrigerazione, causa possibile del deterioramento di prodotti alimentari conservati.




New features



Bus communication for remote control and supervision: the compressor, fans and system controller can be controlled and their faults can be detected remotely.



All the relevant electrical. mechanical and environmental parameters can be measured and logged remotely;



Reduction of maintenance and logistic costs.





The electronic boards accept a wider range of AC power supplies and provide higher immunity to EMI.

Centralized power supply:
simpler and more reliable power distribution





Il software installato legge i parametri in modo interattivo permettendo possibili interventi di manutenzione predittiva.

INNOVATION

I Controlli Elettronici OIO per compressori ermetici a velocità variabile BLDC utilizzano una tecnologia innovativa per la gestione del sistema frigorifero, incrementandone i valori di efficienza.



Electronic Control:
Variable Speed Control




The variable speed is controlled with a signal VS between 0V and 10V referenced to the isolated ground GND.





Electronic Control:
ON/OFF control




The system is also compatible with ON/OFF control of signal ON by connecting it to the isolated ground GND.



OIO Control è in grado di dialogare con i più noti software di gestione in uso alla Grande Distribuzione ponendosi come unica interfaccia tra il sistema frigorifero e il personale tecnico dei punti vendita.

Electronic Control: Monitors





Several parameters are monitored by the system:


supply voltage


motor current


motor speed


motor torque


system temperature


Their monitoring allows protection features as well as advanced functionalities like the speed derating with delivered torque.




OPPORTUNITIES

Il Controllo Elettronico OIO applicato al compressore BLDC garantisce un risparmio energetico nell'ordine del 35% rispetto ai compressori tradizionali.
Gestisce con efficienza tutti i componenti del sistema di refrigerazione, ottimizza le prestazioni senza sprechi energetici e diminuisce sensibilmente le emissioni di CO2 nell'ambiente.

Variable Speed
Compressor


Variable speed compressor is an innovative technology trend in the refrigeration market.

Variable speed motors are constructed with rotors using permanent magnets, wich removes the conduction losses of traditional squirrel cage rotors.

Cooling capacity il approximately proportional to compressor speed, therefore variable spped drive varies the energy delivered by the compressor speed, therefore variable speed drive varies the energy delivered by the compressor: the variable speed compressor provides no more refrigeration capacity than needed by loading conditions.

Speed management of the controller target to operate the variable speed compressor and fans with the minimum thermostat cycles and at the lowest possible speed, resulting in energy savings, better temperature stability over time, extended product life span.


Variable Speed
Condenser Fan


Energy savings could arise from variable speed control of the condensing fan as well: the amount of energy saved by reducing the fan speed is the cube of the speed reduction.

Advanced adaptive algorithms for the speed control of compressor and fans result in energy savings and better temperature stability over time.





Energy savings
up to 35%
