<p><P>PROBLEM TO BE SOLVED: To provide a refrigerating type air dryer achieving energy saving by improving condensation efficiency of the refrigerating type air dryer and decreasing a load of a refrigerating compressor, which dryer is environment-friendly by decreasing noises generated by the refrigerating type air dryer, and in which failures are reduced by eliminating usage of components causing the failures. <P>SOLUTION: In the refrigerating type air dryer, a cooling medium compressed by a compressor 1 is liquified by a condenser, and this liquified cooling medium is vaporized by an evaporating instrument 31 of an evaporator 3, and air introduced into the evaporator 3 is cooled thereby to remove water content. A primary condenser 2 of a spontaneous heat dissipation type for preliminarily condensing the cooling medium is arranged on the downstream side of the compressor 1, and a secondary condenser 4 for condensing the cooling medium preliminarily condensed by cooling the air guided out from the evaporator 3 is arranged on the downstream side of this primary condenser 2. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
