※ Influence of moisture
① Moisture precipitation – Blocked by ice
② Refrigerant and reaction
③ Life reduction of oil
④ Acceleration of oxidization
⑤ Copper plating phenomenon
⑥ Gas dissolution by the interaction of synthetic insulating material (insulator)
※ Influence of foreign substance
① Increase of condensed temperature.
② Increase of temperature.
③ Decrease of cooling efficiency
④ Shorten the life by friction between oil and foreign substance in the compressor.
■ Accumulator
1) Role : To send a pure refrigerant gas to compressor by removing completely the refrigerant liquid
from evaporator.
※ If a refrigerant liquid go into the compressor, overload is occurred.
