Description
DESCRIZIONE dell’invenzione avente per TITOLO: DESCRIPTION of the invention with TITLE:
“Scambiatore di calore a gas espanso di supporto al condensatore in un impianto frigorifero” "Expanded gas heat exchanger supporting the condenser in a refrigeration system"
Gli impianti frigoriferi possono essere schematizzati con quattro componenti principali: il compressore, il condensatore, la valvola di espansione e l’evaporatore. Refrigeration systems can be schematized with four main components: the compressor, the condenser, the expansion valve and the evaporator.
Nel condensatore il gas in uscita dal compressore viene raffreddato prima di essere inviato alla valvola di espansione. In the condenser, the gas leaving the compressor is cooled before being sent to the expansion valve.
Se l’ambiente in cui si trova il condensatore è particolarmente caldo il salto termico tra l’aria che lambisce il condensatore e la sua superficie è minore e questo causa una minore asportazione di calore con conseguenti problemi nell’impianto. If the environment in which the condenser is located is particularly hot, the temperature difference between the air that touches the condenser and its surface is less and this causes less heat removal with consequent problems in the system.
Allo stato attuale della tecnica si ovvia a questo problema montando uno scambiatore a fascio tubiero in cui il gas compresso viene raffreddato da un flusso d’acqua in controcorrente. In the current state of the art, this problem is overcome by mounting a shell and tube exchanger in which the compressed gas is cooled by a counter-current flow of water.
Lo svantaggio di suddetto sistema si ha nel consumo di acqua se lo scambiatore sfrutta acqua corrente e nei dover introdurre un impianto per il raffreddamento dell’acqua se lo scambiatore è a ciclo chiuso. The disadvantage of this system is in the consumption of water if the exchanger uses running water and in having to introduce a system for cooling the water if the exchanger is a closed cycle.
Oggetto della presente invenzione è uno scambiatore di calore che sfrutta il gas espanso del ciclo frigorifero stesso per abbassare la temperatura dell’aria in ingresso al condensatore così da avere maggiore scambio termico. The object of the present invention is a heat exchanger that uses the expanded gas of the refrigeration cycle itself to lower the temperature of the air entering the condenser so as to have greater heat exchange.
Con riferimento allo schema tecnico allegato in Fig. 1 si descriveno ora più dettagliatamente le varie parti di una possibile forma meccanica dell’apparecchio. With reference to the technical diagram attached in Fig. 1, the various parts of a possible mechanical form of the device are now described in more detail.
Esso consta di uno scambiatore di calore ( A ) all’interno del quale entra dal condotto ( E ) gas espanso a bassa temperatura che consente di abbattere la temperatura dell’aria in ingresso al condensatore ( B ) che riceve un fluido caldo dal compressore ( C ) , lo raffredda e lo invia alla valvola di espansione tramite il condotto ( F ). Il flusso d’aria che passa negli scambiatori è alimentato da un ventilatore ( D ). It consists of a heat exchanger (A) inside which enters from the duct (E) expanded gas at low temperature which allows to reduce the temperature of the air entering the condenser (B) which receives a hot fluid from the compressor ( C), cools it and sends it to the expansion valve through the duct (F). The air flow passing through the exchangers is powered by a fan (D).
Quella che si è descritta e rappresentata non è che una delle possibili forme di esecuzione meccanica dell’apparecchio e possono quindi aversi diverse ovvie variazioni che qui sarebbe inutile elencare, senza tuttavia uscire dall’ambito della presente invenzione. What has been described and represented is only one of the possible mechanical embodiments of the device and therefore there may be several obvious variations that it would be useless to list here, without however departing from the scope of the present invention.
