Heat rejection is a prime concern with distributed residential AC as described in this website. Ideally, I like to be able to reject heat to geothermal water cooled system. The design and implementation of this has significant impact on residential construction and building codes. I like to get feedback from building professionals. Geothermal water cooled system requires a PEX pipe circuit running throughout the house. The reason is that in a typical house of 2500Sq. Ft there are about 20 smart microAC units located in almost every wall in the house. This requires water to be circulated to almost every wall in the house.
With my limited knowledge of home construction parctises and building codes, I envisoned a pex pipe system that runs along the perimenter of the house in the basement or crawl space and in the attic. Where a microAC unit is located in first floor the pex line on the basement or crawl space is tapped with a "T" fitting and the water line taken up into that wall above. Similarly, for the microAC units located on the second floor, the pex line in the attic will be tapped with a "T" fitting and the water taken down into the wall below. Now I wonder what a building code expert or a buildin professional have to say about this.
For a home builder, the ducted air culrculation system is no longer required. A central AC system with an outdoor and indoor unit will not be required. While this is considerable redcution in compelxity I wonder if the pex piping through out the house is a concern. Love to reach out to a few experts on their views on this.
