Long-term Durability Test
The air conditioner's main mission is to provide a level of durability that ensures stable
operation for many years. In order to achieve this, we conduct a long-term continuous
operation test. The results of this test, which is conducted under conditions that are much more severe than actual operating conditions, prove the rugged strength of Panasonic air conditioners.
Compressor Reliability Test
After the continuous operation test, we remove the compressor from a selected outdoor
unit, disassemble it, then examine the internal mechanisms and parts for possible failure and durability. Panasonic air conditioners continue to provide their designed performance for many years even after prolonged operation under harsh conditions.
Operating Test in Harsh Conditions
In addition to tests under normal operating conditions, an operating durability test is
conducted in a high-temperature, high-humidity test chamber at a temperature up to
55°C. For use in extremely cold climates, the test is also conducted in a low-temperature test chamber down to -20°C. These tests are conducted to see if there is sufficient lubrication inside the compressor under various operating conditions.
The outdoor unit, which is subject to rain and wind, is provided with IPX4 waterproof
compliance. Potential problems are checked by tests such as showering the unit for a
predetermined amount of time. Contact sections on printed circuit boards are also
resin-potted to prevent adverse effects caused by an unlikely exposure to droplets of
