Sanyo Mini-Split Heat Pump & RFI?

[K6IC]

Am considering installing a Sanyo Mini-Split Heat Pump at my off-grid HammieRadio QTH.  It is touted as an inverter powered variable speed DC compressor,  and is therefore fairly efficient as an ASHP.

Am wondering if anyone here has actual experience with these Sanyo units generating ANY RFI on the HF Ham Bands,  160 through 6 Meters?

Know that these units are from off-shore (prob, mostly from China) and so on, but this is a bit of another topic.  

Would hate to invest in one of these and have to choose twix HF operating,  and some level of comfort.

This mini-split approach seems ideal for the small rooms at this location.

Thanks for any specific info.  Vic

This design of "split unit" is very popular in SE Asia. Cuz it is simple and no need of duct work. They seem to be getting popular in N. America. You can have 4-6 air-handlers on one condenser unit. We were going to have two systems installed in a future retirement home in the Philippines. Duct work in a tropical environment can breed a lot of mold and fungus.
The inverter type is extremely efficient, as for RFI, I would not be able to answer your question.
You should contact the manufacturer before purchasing. Googling your thought brings up the same question but not any one who is a Ham, saying ya or nay. A sound tech in a big church had concerns about RFI to his audio system and they had 8 units installed and not a hint of any hums or buzzes. Ham bands will be different.

The Mitsubishi units are regarded as the very best. They are more expensive. The others are considered copies.

These started showing up on commercial projects about ten years ago. The mechanical engineers we work with are very high on them.

My son has used them on several high end residential projects and likes them.  They first were configured as split units with wasll mounted air handlers but now are available with multiple boxes that look like VAV boxes.

I may use them if I build another house.

Hi Fred,  and Hugh,

SRI for the delay.  The internet at the remote QTH is quite intermittant,  BUT,  still,  it is nice to have something at times,  vs NOTHING!

Thanks for the input.  Will poke around a couple more places before buying anything.
