Duct for circulating fluid in heating and cooling structure i.e. slab floor, has envelope surrounding tube to maintain wire against external surface in which tube, wire and envelope are uncoupled to authorize sliding of wire

摘要

The duct (100) has a flexible tube (110) curved to form a coil. An electrically conductive wire (120) extends along an external surface (114) from the flexible tube. An envelope (130) surrounds the tube to maintain the wire against the external surface in which the flexible tube, the wire and the envelope are mechanically uncoupled with respect to each other so as to authorize sliding of the wire with respect to the tube and with respect to the envelope when the tube is curved. The wire includes an insulating sleeve (122) made of reticulated polymeric material. Independent claims are also included for the following: (1) a heating and cooling structure including a coating layer (2) a method for assembling a heating and cooling structure.
