Air Purging
Air purging
The air and moisture remaining in the refriger-
ant system have undesirable effects as indi-
cated below.
- Pressure in the system rises.
- Operating current rises.
- Cooling(or heating) efficiency drops.
- Moisture in the refrigerant circuit may freeze
and block capillary tubing.
- Water may lead to corrosion of parts in the
refrigeration system.
Therefore, after evacuating the system, take a
leak test for the piping and tubing between
the indoor and outdoor unit.
