As I suspected. From the LG website: "*Inverter Technology is a key attribute
of LG’s new room air conditioners. It is used in conjunction with a
variable-speed compressor and adjusts the compressor motor speed to regulate
temperature. "
If you are okay with the current model, I would put in another one. The
efficiency difference in percentage sounds like a lot, but from a power
consumption standpoint at this size is immaterial.
I went through this agony a couple of months ago when shopping to a whole
house, roof-mounted, packaged heat pump. The latest trend is to use a Bosch
which has an inverter driven variable-speed compressor and variable-speed
condenser fan, plus an ECM blower. The option was another Trane/American
Standard with a two-speed compressor, single speed condenser fan and an ECM
blower.
I did not have objectionable noise from the ECM, but my antennas are >100 feet
from the house. I could not get an answer about the rfi potential of the Bosch
from any source, including here, so took the safe route.

Hi Folks!
I have an LG LW1222ERSM 12,000 BTU air conditioner that sadly needs to be
replaced.
The dimensions are 15x24 going through a framed hole in the wall ofbthec10x16
foot ham shack. This somewhat constrains replacement choices.
I noted that I could buy the same model or an LG LW1222IVSM which is a "dual
inverter" model. I'm not sure of the benefits in buying this inverter model,
but I am a bit concerned over the noise potential of the inverters.
Does anyone have experience with this model or another LG inverter model?
Up to now, I've had no noise issues with the standard model, but since this in
the ham shack, I figured it might be good to ask. Also, the outdoor meter
panel is 20 feet away and the indoor ham shack subpanel is 10 feet away. Power
from the utility transformer is aerial and 160 feet away. The air conditioner
is on a dedicated 20 A 115 VAC breaker from the ham shack subpanel
Thoughts anyone?
