Description

AIR CONDITIONING ADAPTER FOR SHELTERS AND SAFE ROOMS םאתמ גוזימ ריוא םיטלקמל םירדחו םינגומ FIELD OF THE INVENTION The present invention relates to an air conditioning adapter for use with wallsleeves of shelters and safe rooms.
BACKGROUND OF THE INVENTION It is known in life saving protection shelters and safe rooms, to use an air filtrationsystem in the ventilation path. For proper operation of the filtration system, it is requiredthat the protected space is air tight sealed and slightly over-pressured by forcingventilation trough the filtration system. The over-pressure prevents entrance of potentiallycontaminated air through a possible worn-out sealing of the protected space. Typicallythere are provided an air intake wall sleeve fitted to an exterior wall of the building, and anair exhaust wall sleeve fitted to a preferably opposite interior wall of the safe room. Theair intake wall sleeve is airflow coupled to the filtration system. And the air exhaust wallsleeve is provided with an over-pressure relief valve. In modern installations the filtrationsystem is directly mounted to the air intake wall sleeve.For general purpose use of the protection shelter or safe room during normal times,it is desired that the space is air conditioned. However, installation of an air conditioningsystem requires a wall opening to facilitate installation. Such a wall opening should enableinsertion of a flexible air duct of the kind typically used in central air conditioningsystems, or several pipes, cables and conduits such as used in cases of split airconditioning systems. Such wall openings if incorrectly made violates defense regulationsand deteriorates the air tightness of the protected space.For that purpose it is required and widely accepted to install an additional wallsleeve having a flange on the internal side of the wall and a removable cover-plate fitted tothe flange with bolts and nuts. In cases where a central air conditioning system is installed,a flexible air duct is directly attached to the external side of the wall sleeve and the cover-plate is removed. The cover-plate should be kept in the protected space and may be refittedin case of warfare hazard.
In cases where a split air conditioning system is installed, it is known to usededicated fittings that enable a seal-able passage of the several pipes, cables and conduitsthrough the wall sleeve. Such fitting is disclosed in Israeli patent 218946 to Skurnik,describing a resilient block of material with through holes for conduit passage and endplates to press the resilient block of material and shrink the holes about the conduits. Adraw back of the described solution is the need to install a dedicated wall sleeve duringconstruction of the building. Other known solutions for installation of a split air conditioning system includeusage of several cable glands which are fitted to the removable cover-plate and tightenedover the several conduits, cables and pipes after installation. In reality it was found that in most cases where a central air conditioning systemwas installed and the cover-plate removed, it was lost shortly after installation and was notavailable in an event of emergency.Additionally it was found that in cases where a standard wall sleeve was fittedduring construction of the building and a split air conditioning system eventually installed,the cover-plate was removed and the pipes, cables and conduits were freely passed throughthe wall sleeve without any sealing. In such case even if the cover-plate is still available itis not possible to fit it back in an emergency due to the through passing conduits.Consequently, there is a need to improve the task of air conditioning shelters and saferooms.
SUMMARY OF THE INVENTION Accordingly it is a principal object of the present invention to provide acomprehensive solution for both types of air conditioning installations that is persistentlyavailable. Such that in an event of an emergency, preparation elements are readilyaccessible and easy to implement. An air conditioning adapter for shelters and safe roomsmade according to the invention renders one or more of the advantages below: 1.
