Title: Sinusoidal layout for floor heating pipes - has degree of heat release at each pipe bend altered by changing spacing of sections inside one another
Inventor: BOSCH ROLAND
IPC: F24D3/14
Filed: 1975-09-27
Abstract: The arrangement for floor heating installations comprises pipes which extend in alternate directions parallel to each other and which are distributed over the floor surface area to be heated. The pipes are laid sinusoidal each with at least two 180 deg. curved sections (16, 17; 18, 19) succeeding each other in the same direction. The arrangement reduces the number of curved sections of small dia. Every other pipe bend has three times the dia. of curvature, which reduces a release of heat at this bend. The degree of heat release per bend can be varied by forming the bend from two 90 deg. curved sections of smaller dia. of curvature, where an increase in heat release is desired. The increased heat release in the curved region is not concentrated along a line close to the wall, but occurs within a wider band.
