Air System Equipment Air Conditioning Westinghouse--Slurlevanl Division AIR WASHERS Three types are available--Types S and H, with one bank of nozzles, used pri marily for humidifying;Type C, with two banks of nozzles, used for evaporative cooling, humidifying and dehumidifying. FILTER-WASHERS Self-cleaning filter-washers employ a bank of mineral wool, or glass fiber filter pads, in conjunction with water sprays to clean and humidify the air. Made in 72 standard sizes and to specifications. SURFACE DEHUMIDIFIERS Available for either chilled water or directly expanded refrigerant, these wet surface units control accurately wet and dry bulb conditions in industrial and comfort air conditioning systems. Ca pacities range from 2000 to 50,000 cfm, with cooling capacities of 5 to 250 tons of refrigeration. AIR BLENDERS Widely used for central air conditioning and ventilating systems in commercial buildings, the Air Blender mixes cool de humidified air or heated humidified air from a central system with predeter mined quantities of recirculated air to maintain room temperatures for both winter and summer, air conditioning. It has no moving parts, and is equipped with a heating coil for winter operation. All units are built with 7 in. front-toback dimensions, and in nominal lengths of from 18 in. to 60 in. UNIT CONDITIONERS Unit Conditioners, Type UC, provide year 'round air conditioning-coolingdehumidifying to individual room areas in such structures as hotels, apartments, office buildings and hospitals. For cooling or heating, water is supplied at the required temperature from a cen tral system. Air circulation and air cleaning is provided by the unit through out the entire year. Unit Conditioners may be used in com binations with a conditioned, central ventilating air system to recirculate and cool the air conveyed to a room, or may be individually applied to cool and dehumidify recirculated room air. Air capacities range from 300 to 700 cfm, Btu per hour from 5400 to 16,200. 1178 Air System Equipment Air conditioning Westinghouse--Slurlevanl Division UNITAIRE AIR CONDITIONING UNITS Central Plant Type Unitaires are com pletely self-contained, with all the com ponent parts of an air conditioning system, designed especially for installa tion with supply and return air ducts. Unitaires are completely assembled, piped, refrigerant-charged, wired and ad justed at the factory. Each is given- a complete operating test to assure satis factory performance when installed. All that is required is connection of water and electrical service and attachment to the duct system. The condensing unit is a standard Westinghouse hermetically-sealed, direct-connected compressor, with watercooled condenser, isolated from the supporting structure by rubber anti-vi bration mountings. Central Plant Type Unitaires are avail able with 7, 10, 15. 20 and 25 hp com pressors. ' Self-Contained Type Unitaires are widely used in small stores, restaurants, office suites and similar establishments. Usually they are installed in the room to be air conditioned, but in many cases they are remotely--located with ducts supplying one or more spaces with air conditioned air. Available in sizes of 1, 2, 3 and 5 hp. Westinghouse Unitaires offer many important features: 1. Compact Size--Largest unit occu pies less than 7 sq ft of floor space; smaller units often installed on shelves. 2. Attractive Appearance. 3. Completely Factory-Built. 4. Flexible Application. 5. Westinghouse Hermetically-Sealed Compressor. 6. Quiet Operation. U79
