DESCRIZIONE DESCRIPTION
Campo di applicazione Field of application
Oggigiorno è sempre più sentita l’esigenza di avere un adeguato comfort termico anche negli grandi spazi industriali e commerciali, sia nella fase Invernale che in quella Estiva, garantendo contemporaneamente un contenimento (o riduzione) dei consumi energetici. Nowadays the need is increasingly felt to have adequate thermal comfort even in large industrial and commercial spaces, both in the winter and in the summer, while ensuring a containment (or reduction) of energy consumption.
Per i grandi spazi industriali/artigiahali, la necessità di avere una migliore qualità dell’aria interna, unita ad una corretta distribuzione della stessa in modo più uniforme possibile, al fine di limitare la stratificazione e quindi le dispersioni dall’alto, richiede sistemi di trattamento dell’aria in grado di garantire una circolazione dell’aria ambiente di circa 2-3 volumi ambiente/ora. La presente invenzione concerne un apparecchio di riscaldamento e raffrescamento adiabatico dell’aria ad alta efficienza, destinato ad essere impiegato in ambito industriale e commerciale, nonché in cicli di processo. For large industrial / artisan spaces, the need to have a better indoor air quality, combined with a correct distribution of the same in the most uniform way possible, in order to limit the stratification and therefore the dispersions from above, requires systems of air treatment able to guarantee an ambient air circulation of about 2-3 ambient volumes / hour. The present invention relates to a high efficiency adiabatic air heating and cooling device, intended for use in the industrial and commercial fields, as well as in process cycles.
Si presta ad essere posizionato direttamente all’interno degli ambienti da climatizzare, oppure all’esterno, sia all’aperto che in apposito locale (centrale termica) e risulta pure facilmente collegabile a canalizzazioni per la distribuzione dell’aria. Costituisce un monoblocco di facile posizionamento e fissaggio. It lends itself to being positioned directly inside the rooms to be air-conditioned, or outdoors, both outdoors and in a special room (thermal power plant) and is also easily connected to ducts for air distribution. It constitutes a monobloc of easy positioning and fixing.
Lo stato dell’arte The state of the art
Esistono da anni sul mercato diversi apparecchi di riscaldamento e raffreddamento dell’aria monoblocco che montano a bordo un generatore termico per il riscaldamento dell’aria ed una serie di batterie sia ad espansione diretta (alimentate cioè da una molo condensante di un chiller o pompa di calore elettrici), sia con acqua calda o fredda. Questi apparecchi, anche si Relazione brevettuale For years there have been various monobloc air heating and cooling appliances on the market that are fitted with a heat generator for air heating and a series of batteries both with direct expansion (i.e. powered by a condensing dock of a chiller or pump electric heat), either with hot or cold water. These appliances, even you Patent report
garantiscono una circolazione dell’aria ambiente di circa 2-3 volumi ambiente/ora, presentano comunque l’inconveniente di avere elevati consumi elettrici, sia per far funzionare i ventilatori ad alta prevalenza necessari, sia per alimentare i chiller a compressione elettrica necessari per il raffreddamento dell’aria. La pulizia dei filtri poi deve essere eseguita manualmente e per particolari ambienti di lavoro polverosi questo comporta un gravoso onere. Esistono inoltre sul mercato apparecchi monoblocco di solo raffreddamento adiabatico delParia, installabili sia all’interno che all’esterno dell’ambiente con possibilità di canalizzazione dell’aria stessa. La portata d’aria trattata dalle singole unità è comunque limitata ed un sistema di filtraggio non è presente. guarantee a circulation of the ambient air of about 2-3 ambient volumes / hour, however they have the drawback of having high electrical consumptions, both to operate the high-pressure fans necessary, and to power the electric compression chillers necessary for the air cooling. The cleaning of the filters must then be carried out manually and for particular dusty work environments this entails a heavy burden. There are also monobloc appliances on the market for adiabatic air cooling only, which can be installed both inside and outside the environment with the possibility of channeling the air itself. The flow of air treated by the individual units is however limited and a filtering system is not present.
Presentazione dell’invenzione Presentation of the invention
In tale contesto quindi, scopo principale della presente invenzione è quello di superare l’inconveniente della tecnica già nota sopra descritta, presentando un apparecchio di riscaldamento e raffreddamento adiabatico dell’aria ad alta efficienza destinato ad essere impiegato prevalentemente nella climatizzazione degli ambienti in ambito industriale, nonché in cicli di processo. In this context, therefore, the main purpose of the present invention is to overcome the drawback of the known technique described above, presenting a high efficiency adiabatic air heating and cooling device intended to be used mainly in the air conditioning of environments in the industrial sector. as well as in process cycles.
Ulteriore scopo della presente invenzione, è quello di presentare un apparecchio di riscaldamento e raffreddamento adiabatico dell’aria ad alta efficienza, dotato, a monte del gruppo ventilante, di un sistema di filtraggio innovativo per quanto riguarda la manutenzione e pulizia automatica tramite getti d’acqua. A further object of the present invention is to present a high efficiency adiabatic air heating and cooling device, equipped, upstream of the fan unit, with an innovative filtering system as regards the maintenance and automatic cleaning by means of water jets. water.

L’apparato comprende inoltre mezzi di raccolta di detto liquido posti sostanzialmente al di sotto di detti mezzi evaporativi e mezzi di lavaggio fissati internamente a detto condotto di contenimento rivolti verso detto gruppo di filtraggio, i quali mezzi di lavaggio spruzzano il flusso di almeno un secondo liquido su detto gruppo di filtraggio, per la rimozione di particolato filtrato; detto secondo liquido essendo convogliato in detti mezzi di raccolta. La pulizia ad acqua del gruppo filtrante, può operare in modo automatico (o programmabile a tempo dopo un certo numero d’ore di funzionamento) qualora il livello di intasamento dei filtri risulti elevato. I filtri sono comunque rimovibili e facilmente sostituibili. Periodicamente, in modo automatico, l’acqua nella vasca viene scaricata in modo da evitare problemi legati alla stagnazione della stessa. a high air flow rate and low electrical absorption thanks to the facilitated path of the air that crosses the heating section located downstream of the fan unit itself. The apparatus further comprises collection means for said liquid located substantially below said evaporative means and washing means fixed inside said containment duct facing towards said filtering unit, which washing means spray the flow of at least one second liquid on said filtering group, for the removal of filtered particulate; said second liquid being conveyed into said collection means. The water cleaning of the filtering group can operate automatically (or programmable by time after a certain number of hours of operation) if the clogging level of the filters is high. The filters are however removable and easily replaceable. Periodically, automatically, the water in the tank is drained in order to avoid problems related to its stagnation.
Vantaggiosamente il gruppo di ventilazione è posto internamente al condotto di contenimento tra detto gruppo di filtraggio e detto gruppo riscaldante. Advantageously, the ventilation unit is placed inside the containment duct between said filtering unit and said heating unit.

In particolare risulta dotato di un plenum posto all’esterno dei mezzi evaporativi, equipaggiato con serrande d’aria per poter gestire indifferentemente la quota di ripresa aria ambiente, la quota di aria esterna di rinnovo, sia quando la macchina è installata all’interno, sia quando è installata all’esterno (in parete o in copertura), o in apposito locale (centrale termica). The apparatus also includes at least one shut-off damper for the air drawn in through said inlet section. In particular, it is equipped with a plenum placed outside the evaporative means, equipped with air dampers to be able to manage indifferently the amount of room air intake, the amount of external renewal air, both when the machine is installed inside, both when it is installed outdoors (on the wall or on the roof), or in a special room (boiler room).
