<p>PURPOSE:To provide a small-sized refrigerating dryer in which an air compressor and a dryer are integrated into one body so as to cause no mutual interference between them even if only single fan is used. CONSTITUTION:A refrigerating dryer is equipped with a refrigerant circuit 1 consisting of a refrigerant compressor 2, a condenser 3, a pressure reducing device 4 and a cooler 5 and an air supplying device 8 for passing air to be cooled around the cooler 5. A bypass 11 communicating to the inflow side of a compressor 2 from a space between the condenser 3 and the pressure reducing device 4 installed. A heat receiver 13 is installed in the bypass 11 and heat of the condenser 3 is transferred thereto. Switching valves 14 for opening and closing the bypass 11 are installed in the refrigerant circuit 1 and the bypass 11, respectively.</p> |
