Abstract
Un metodo ed un'apparecchiatura per sbrinare lo scambiatore di calore esterno di un impianto a compressione di vapore od a pompa di calore, reversibile. Il metodo e l'apparecchiatura sono particolarmente idonei all'impiego in impianti minori che utilizzano un unico motore dei ventilatori per comandare sia il ventilatore interno che quello esterno. Un'apparecchiatura accumulatrice di calore è montata in relazione di scambio termico con la tubatura del refrigerante fra la valvola invertitrice di flusso dell'impianto e lo scambiatore di calore interno. Durante il funzionamento nel modo operativo a riscaldamento, calore dal refrigerante viene trasmesso a, ed accumulato in, l'apparecchiatura accumulatrice di calore. Durante il funzionamento nel modo operativo a sbrinamento, il flusso di refrigerante nell'impianto viene allineato come nel modo a raffreddamento, ma con nessuno dei due ventilatori in funzione. Calore accumulato nell'apparecchiatura accumulatrice di calore viene trasmesso a, e sfruttato per sbrinare lo scambiatore di calore esterno. L'apparecchiatura non influisce sul funzionamento dell'impianto nel modo operativo a raffreddamento.
