Abstract

Un apparecchio condizionatore d'aria che dispone di un modo operativo a deumidificazione, per cui l'apparecchio è in grado sia di raffreddare che deumidificare aria in uno spazio da condizionare, nonché di deumidificare aria nello spazio senza raffreddamento sensibile dell'aria. L'apparecchio ha due scambiatori di calore nella sua sezione interna e due scambiatori di calore nella sua sezione esterna. Nel modo a raffreddamento, l'apparecchio opera in modo assai simile ad un convenzionale condizionatore d'aria a compressione di vapore, con entrambi gli scambiatori di calore esterni che operano in serie come singolo condensatore ed entrambi gli scambiatori di calore interni che operano in serie come singolo evaporatore. Una valvola invertitrice a quattro vie commuta per far combaciare l'apparecchio con il suo modo a deumidificazione. In tale modo operativo, refrigerante caldo viene diretto verso uno degli scambiatori di calore interni prima di pervenire ad uno degli scambiatori di calore esterni, il quale continua a fungere da condensatore. Il refrigerante raffreddato bipassa il secondo scambiatore di calore esterno prima di passare attraverso il secondo scambiatore di calore interno che continua a fungere da evaporatore.
