. Cooling apples and pears in storage rooms. Apples Cooling; Pear Cooling. BN-11799-X i1 re 13.—A high-velocity 'outlet distribution system with duct over center aisle. Outlet nozzles shown blow air to sidewall and back through fruit. systems are always provided with some type of discharge nozzle for efficient conversion of the pressure energy in the duct to velocity energy in the emergent airstream. Another system which distributes air in the same manner as the medium- and high-velocity outlet systems with horizontal travel is the multiple overhead unit system (fig. 15). Here, separate cooling units may be placed in the over- head space above the aisle and arranged to blow to the side walls, creating a pattern of circulation and aspirating a quantity of secondary air in the same manner as the high-velocity outlet system. Sometimes one or two pairs of units are used in each 20-foot section of the building; in other cases, units of larger capacitv are used in every second or thud section of the building, and air is.
