Pannelli solari termici a circolazione naturale
Schema impianto a circolazione naturale
I sistemi solari termici a circolazione naturale sono così chiamati perché sfruttano la proprietà dei corpi caldi di salire in modo naturale. Si tratta di una soluzione impiantistica semplice e economicamente vantaggiosa, ideale per privati e famiglie.
Come funzionano?
Scopriamo il funzionamento di questi impianti seguendo lo schema.
(A) I raggi del sole scaldano il liquido solare (acqua + antigelo) che, contenuto nei tubi interni al collettore termico, sale in modo naturale fino a raggiungere il serbatoio posto orizzontalmente sopra i pannelli. (B) Qui il liquido cede il calore all’acqua interna al serbatoio che, riscaldata dal sole, entra nel circuito idraulico sanitario della casa.
INVERNO
D’inverno o in periodi di prolungato brutto tempo, l’acqua scaldata dal sole passa attraverso la caldaia prima di entrare nel circuito idraulico della casa. In questo modo l’acqua entra in caldaia già preriscaldata dal sole, riducendo i consumi di gas o gasolio.
ESTATE
In estate l’acqua scaldata dal sole entra direttamente nel circuito idraulico sanitario della casa, senza alcun riscaldamento integrativo da parte della caldaia.
I principali vantaggi di questi sistemi:
1. Costo limitato.
2. Semplice installazione.
3. Molto convenienti per usi prevalentemente estivi o in località con elevata insolazione.
