Abstract
A refrigeration air dryer outputs dehumidified air dehumidified by a cooling operation using a low-temperature refrigerant after the temperature thereof has been raised by exchanging heat with a high-temperature refrigerant at a reheater. The refrigeration air dryer includes a temperature sensor which detects the temperature of secondary air in the outlet pipe, valve means which adjusts the flow rate of the dehumidified air or the flow rate of the refrigerant flowing through the reheater, and a temperature controller which adjusts the flow rate of the dehumidified air or the flow rate of the refrigerant by controlling the valve means based upon the detected temperature detected by the temperature sensor, thereby maintaining the temperature of the secondary air at a constant level.
