I think this topic needs a separate thread for more clarity to evolve for me.

The rotary compressors used in the small capacity Room Acs have less life compared to a recip or scroll compressor. I wonder if a rotary can be a reliable choice - purely on reliability front - in a VRF where the charge qty is very high, the tubing lengths are long, chances of contamination from tubes are more etc. It will be interesting to hear from people who have handled both rotary inverters and scroll inverters. Thanks!
