puntloos Posted July 30, 2021 Share Posted July 30, 2021 My house has designed a pretty major service shaft (600x350mm) which should theoretically fit at least one of these insanely insulated (300mm?) cold air hoses that comes from a house central chiller coil w/ high speed fan such as https://www.invisible.ac/#product My question: When the cold air comes down from the loft, where, and how does one split these pipes? Do you put 'one hole' in every room? or smallish (100mm?) pipes through the void? Link to comment Share on other sites More sharing options...
Mr Punter Posted July 30, 2021 Share Posted July 30, 2021 I have never heard of this before. I see it is meant to do heating, cooling and ventilation. Do they do a system design for you? Link to comment Share on other sites More sharing options...

Pictured is the 14kw cooling unit (effectively a fan coil unit - the two copper pipes take the coolant (water I assume) - but with high speed air to service a house). As you can guess the output duct is 300-odd mm. Link to comment Share on other sites More sharing options...
