Analysis of Modification of Car AC Compressor to Split AC Compressor on Cooling Rate

Control of Linear Compressor System Using Virtual AC Capacitor

Recently, linear compressors of cooling systems such as refrigerators, which have a free piston driven by a linear motor, have attracted much attention because of their high efficiency. For structural reasons, linear compressors applied in refrigerators should use an AC capacitor to ensure stable control. However, AC capacitors are expensive and bulky. In this paper, we propose a new method to ...

Sealing 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...
