Abstract
A refrigeration air dryer, which dehumidifies compressed air by cooling the air at a cooler by exchanging heat with a refrigerant, includes a first reheater and a second reheater. The first reheater has a configuration in which warm and moist primary air to be dehumidified is preliminarily cooled by exchanging heat between the primary air and low-temperature dehumidified air dehumidified by the cooler, and is transmitted to the cooler. At the same time, the temperature of the humidified air is raised, and the humidified air is transmitted to the second reheater. The second reheater has a configuration in which the humidified air having a temperature raised by the first reheater is again raised by exchanging heat with the high-temperature refrigerant compressed by the refrigerant compressor, following which the humidified air is externally discharged as secondary air.
