Refrigerant Line

Restriction in the refrigerant line will be indicated by:

1. Suction line — A restricted suction line will cause

low suction pressure at the compressor, low
discharge pressure and little or no cooling.

2. Discharge line — A restriction in the discharge line

generally will cause the discharge line to leak.

3. Liquid line — A liquid line restriction will be

evidenced by low discharge and suction pressure
and insufficient cooling.

Refrigerant flexible hoses that have a low permeability
to refrigerant and moisture are used. These low
permeability hoses have a special nylon layer on the
inside.
