Single  Hole Technology

Why and Where is it From
UKT Air Conditioner Without External Condenser
The Single Hole Technology, Also Known as "UKT Concept" In The Air Conditioning Field Has Been Invented and Developed in Italy By Two Italian Automotive Engineers Fabrizio And Giuliano Ungarelli More Than Two Decades Ago, With the Purpose to Eliminate the External Condenser Unit Which Affects The Image and The Architectural Quality of the Urban Areas...

The Two Engineers Transferred Their Knowledge and Focused to  Develop New FluidDynamic Solutions and Alternatives to Solve
Such a Challenge Making Air Conditioning Work Through a Single Hole Crossed By Two Concentrical pipes"....
Typical Air Conditioning Landscape  in Most of the Modern World Capitals
" The Research & Development That the Ungarelli's Introduced, Shortly Become a Case of Study Still
Up-To-date in These Times"
Schematic
of The Concept
…“In 1998 the American academic R. Nathan told the N.Y. Times that, along with the “civil rights revolution” , Air Conditioning had been the biggest factor in changing American  Demography and politics”…
