condensed moisture, oil and solids are separated from the compressed air and
discharged from the system by an automatic condensate drain trap. The cold
compressed air, enters the shell side of pre-cooler. By removing heat from the
incoming air, the outgoing air is reheated.
In the refrigeration system, the compressor compresses low temperature,
low-pressure refrigerant into high temperature, high-pressure gas. The
compressed refrigerant gas flows through the discharge line to a condenser, where
the gaseous refrigerant is condensed into a high-pressure liquid, by exchanging
heat to the cooling airflow. The high-pressure liquid refrigerant reduces to a low
pressure, low temperature mixture of liquid and vapor after passing through the
thermostatic expansion valve and evaporator as it takes heat from the compressed
air. The low-pressure refrigerant gas leaves the evaporator and flows to the liquid
refrigerant accumulator, ensuing that only gas is returned to compressor. The
accumulator prevents liquid refrigerant from entering the compressor and causing
severe damage to the compressor. Refrigerant travels through the suction line to
the compressor where the refrigeration cycle again starts.
INSTALLATION
Mounting
1. A dry, well-ventilated area is the best location for installation of the dryer. It
also should be in an area where the ambient temperature will not exceed 40
°
C or
fall below 2
°
C.
2. A dryer should be kept at a distance from the air compressor in order to prevent
