There was a different approach to this called the "MyTemp system" [1] by a company called "Home Comfort Zones". Home Comfort Zones has been acquired by a company called "Emme E2MS LLC" [2]. The MyTemp system used pneumatically inflated, vacuum pump deflated "pneumatic damper" devices (balloons, if you will) in the distribution lines. It included plenum sensors for temp and pressure, pumps and hardwired per-room thermostats. It looked good to me but a system for my home would have cost about $12,000 if I recall correctly (just for the controls added onto an /existing/ system). With that amount of money, I might have instead have a mini-split variable-rate air conditioning system installed and achieved better savings long term. But both are out of my price range for a retrofit; the target market was very high end. ----- [1] [PDF] www.mytemperature.com/pdf/MyTemp_for_Existing_Homes.pdf [2] http://www.getemme.com/homecomfortzones.php |
