Presentiamo oggi una soluzione di retrofit per un supermarket<\/strong>, dove motori tradizionali AC sono stati sostituiti con motori elettronici EC<\/strong><\/a> regolabili con segnale 0-10 V. La sostituzione \u00e8 stata effettuata intervenendo su tutte le unit\u00e0 ventilanti installate su banchi frigo<\/strong>, evaporatori<\/strong><\/a> e chiller<\/strong><\/a> in funzione nel supermarket.<\/p>\n

\"motori<\/a><\/p>\n

L\u2019installazione di ventilatori elettronici con motore EC e rotore esterno ha portato importanti benefici innanzitutto a livello di una minore potenza assorbita<\/strong>, con un risparmio nel consumo annuo pari a 138.970 kWh, quasi un terzo della potenza<\/strong> in precedenza assorbita dai motori AC.<\/p>\n

A fronte di un costo di investimento iniziale superiore, l\u2019installazione di motori EC porta quindi un secondo grande beneficio, in quanto questa tipologia di motori \u00e8 esente da costi di manutenzione<\/strong>, costi che di contro in 10 anni di manutenzione sui motori AC sono stimati in 72.000 euro.<\/p>\n

\"retrofit<\/a><\/p>\n

\"EC<\/a>La sostituzione in retrofit dei motori AC con motori EC<\/a><\/strong> sulla totalit\u00e0 di banchi frigo, evaporatori e chiller<\/a><\/strong> in uso nel supermarket ha quindi portato a un risparmio stimabile in 21.527 euro l\u2019anno<\/strong>.<\/p>\n

Nel caso specifico, considerando un costo energia pari a 0,11 \u20ac\/kWh, per la totalit\u00e0 del parco installato si ottiene il seguente confronto:<\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

Totale spese motori AC<\/strong> in 10 anni:
\n– 12.800 \u20ac investimento
\n– 72.000 \u20ac manutenzione
\n– 381.568 \u20ac costi funzionamento<\/p>\n

Somma totale sui 10 anni: 466,368 \u20ac<\/strong> – spesa annuale pari a 46.637 \u20ac<\/p>\n

Totale spese motori EC<\/strong> in 10 anni:
\n– 22.400 \u20ac investimento
\n– 228.701 \u20ac costi funzionamento<\/p>\n

Somma totale sui 10 anni: 251.101 \u20ac<\/strong> – spesa annuale pari a 25.110 \u20ac<\/p>\n
