I am working on split type AC compressor. I actually want to know, if i changed the frequency of the compressor to run on different power level, will it affect the life of the compressor. My actual work to run the Compressor with different power level. I will use VFD ( variable frequency drive) to change the frequency of compressor and it will take different power with respect to the frequency. can you tell me that all rotary compressor is designed for a specific frequency. ?
The answer is, we don't know what compressor you have so we can't answer definitively. MANY compressors are indeed designed to operate at a very narrowly specific speed because the lubrication of it is dependent on that speed. Also, are you working with a compressor that would use a 3 phase motor? Because for the most part VFDs only work on 3 phase motors. There are a few that work on SOME types of single phase motors, but the type of motors that will work are not the types that are typically used on compressors.
