B) Dryer label
The following label is affixed on the cabinet of the refrigerant compressed air dryer.
C) Working details
1) Refrigerant circuit:
The refrigerant circuit can be divided in 3 parts:
A)
Low pressure section with an evaporator (heat exchanger)
B)
High-pressure section including: Condenser, liquid receiver, (if installed) and the filter dryer.
C)
Control circuit including: Compressor, Expansion valve, by-pass valve (if installed),
Fan pressure switch (if installed)
2) For water - cooled dryers:
A) Water valve
B) Safety high pressure switch (if installed)
3) The Refrigerant circuit operates as follows:
A) The compressor compresses gaseous refrigerant to a high temperature.
B) The hot refrigerant condenses in the condenser. Being liquefied it is stored in the liquid receiver (if installed).
C) The liquid is taken out the storage vessel and injected in the evaporator (heat exchanger) by an expansion valve.
This expansion valve is protected by a filter, which removes particles and humidity that could be in the circuit.
D) The injected liquid fills in the refrigerant section of the air / refrigerant heat exchanger and evaporates by taking
out the calories from the compressed air. The gaseous refrigerant is sucked in the compressor and the cycle carries
on.
E) In order to keep the evaporation pressure steady, and thus the refrigerant temperature in the heat
exchanger, a by-pass valve is injecting hot gaseous refrigerant in the circuit. On certain dryers, an
automatic expansion valve regulates this.
4) Compressed air circuit:
A)
The saturated hot compressed air flows into the Economiserwhere it is pre-cooled by the out flowing dry chilled
air. In the cold zone of the air refrigerant section it continues to cool down to dew point and enters the separator
where condensates are collected. The outgoing chilled air is then warmed up in the economizer by the hot
incoming air.
