I don’t have any first hand experience with it, but there is a “Smartcool products and how they work” link on their website that includes a request for the white paper, which is probably about as much info as you will be able get as to how it operates.
Here is the link. http://www.smartcool.net/technology...itioning-compressors-reduce-electricity-usage
Also found this link to an Eco3 presentation transcript…. Don’t know if it will be of help though. http://www.slideshare.net/sdas61/dnssmartcooleco3
