What is a liquid line filter drier?
Just so, how do I know if my liquid line filter drier is clogged?
A symptom of a clogged liquid line filter drier is a temperature drop across the filter drier. Filter driers are typically shaped like a hot dog and are about the same diameter.
Furthermore, what's inside a filter drier? The most common materials used in filter drier construction are activated alumina and molecular sieve. Activated alumina is used for removing organic acid molecules from refrigeration systems.
Similarly, which direction does a liquid line filter drier go?
Point the arrow in the correct direction. Suction driers point towards the compressor and away from the evaporator. Liquid line driers point toward the metering device and away from the condenser. A liquid line drier goe in the liquid line NOT in the discharge line.
How do I know if my filter drier is bad?
Symptoms of a restricted liquid line include:
- A higher than normal discharge temperature;
- High superheats;
- Low evaporator pressures;
- Low condensing pressures;
- Normal to slightly high condenser subcooling;
- Low condenser splits;
- In some cases, a local cool spot or frost after the restriction;
- A low amp draw; or.
