The Relationship Between Deposit Formation and Oil Leakage of Lip-Type Seal for Automotive Air Conditioner Compressor
نویسندگان
چکیده
Open structure compressor is used for the compressor of automobile air-conditioner due to the drive by engine. This means shaft seal should be necessary for sealing of oil & freon gas of compressor inside. Now, lip type seal with elastic rubber lip and PTFE lip takes the high market share instead of mechanical seal and gains popular favor. More high speed , temperature and pressure are recently asked for customer's test spec. and the deposit generation of rubber lip sliding area was often investigated at leakage samples as the results. Much leakage oil finally causes the magnet clutch slip and function down. This paper indicates the deposit formation has the relation with lip wear , oil temperature etc. and the countermeasure to prevent the deposit.

High Efficiency Compact Rotary Compressor Using the New Refrigerant HFC-134a for Automotive Air Conditioners
In accordance with worldwide consensus, the use of chlorofluorocarbons, which play an important role in damaging the ozone layer, should be completely abolished by the end of 1995. This provided the impetus for developing the three vane rotary compressor. Formerly CFC-12 was used as the refrigerant in automotive air conditioners, until HFC-134a was substituted for CFC-12. In response to the cha...

Therefore, higher compression ratio, higher reliability and larger capacity are obtained by introducing 3D scroll. Since the 3D scro...
متن کاملSealing Performance of a Mobile AC Compressor Shaft Seal
In the last years, environmental concerns such as the destruction of the ozone layer and global warming led to the demand of tighter air conditioning (AC) systems. The compressor has been identified as the most emissive component of the AC system. Due to its complex structure and sealing mechanism, the shaft seal is the leak-prone part. This paper presents an experimental study of several lip s...

There are two kinds of dual split type air-conditioner. One is of using two compressors for two indoor units; the other has only one compressor for two indoor units. The EER and refrigerating capacity of the former kind are just the same as the single split type's. But to one compressor dual split type system, there are two working ways: 1. compressor and both two indoor units operating, and 2....
