PRODUCT SPECIFICATIONS
■ Dryer
1) Role : Absorb the moisture from the refrigerant that refrigeration cycle circulates and eliminate the foreign substance.
2) Structure : If even some moisture is included refrigerant is impossible to circulate by freezing the small capillary outlet, so silica
gel or molecular sieve is (included and) sealed to absorb the internal moisture, and install a minute net to eliminate the
foreign substance.
※ 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.
