==Function== | |||
Refrigeration dryers employ two heat exchangers, one for air-to-air and one for air to refrigeration. However, there is also a single heat exchanger that combines both functions. The compressors used in this type of dryer are usually of the hermetic type and the most common gas used is R-134a. The goal of having two heat exchangers is that the cold outgoing air cools down the hot incoming air and reduces the size of compressor required. At the same time the increase in the temperature of outgoing air prevents re-condensation. | Refrigeration dryers employ two heat exchangers, one for air-to-air and one for air to refrigeration.
