A hydraulic manifold for a hydraulic heating and/or cooling system includes a feed conduit (212) and a return conduit (216). The feed conduit (212) includes at least one feed connection (258), and the return conduit (216) includes at least one return connection (260), for the connection of a load circuit (228). A load module (204), in which a section of the feed conduit (212) with the feed connection (258), and a section of the return conduit (216) with the return section (260) are formed, includes at least one mixing device with a pump (232) and with a regulating valve (230), to admix fluid from the return connection (260) to a fluid flow from the feed conduit (212) to the feed connection (258). The section of the feed conduit (212) and the return conduit (216) in each case include an additional contact for connection with a further load module.

A heat radiating pipe (2) that is disposed in a hot water mat (1) is extended from the hot water mat (1) to provide an extended portion that is used as connecting pipes (2a and 2b) to a heat source machine (11). The construction makes it possible to prevent a water leak as there is no connection therebetween, and reduces costs for parts and installation as no connection tool, such as a coupler, is used. Further, guide pieces (13 and 14) attached with cover members (17) are arranged at positions where the connecting pipes (2a and 2b) are extended, and the connecting pipes (2a and 2b) are disposed by using the guide pieces (13 and 14), so as to efficiently utilize heat radiated from the connecting pipes (2a and 2b), and to prevent thermal loss.

A flooring underlayment comprises a membrane that includes a body panel having a panel top surface and a panel underside surface spaced apart from the panel top surface by a panel thickness. The membrane further includes a plurality of dimples projecting downward from the panel underside surface, each dimple having a dimple upper end open to the panel top surface, a closed dimple lower end spaced apart from the dimple upper end by a dimple height, and a dimple sidewall extending between the dimple upper end and the dimple lower end, the dimple sidewall configured to inhibit collapse of the dimple height when a load is applied to the flooring underlayment during use. The membrane includes a plurality of grooves open to the panel top surface and formed within a groove body projecting downward from the panel underside surface, each groove shaped to receive an elongated heating element therein.

A circulation pump assembly for a heating and/or cooling system includes an electric drive motor (108) and a connected pump housing (106) in which at least one impeller (118) is situated and which comprises a first inlet (112) and a first outlet (114). The pump housing (106) includes a second inlet (122) which is connected in an inside of the pump housing (106) at a mixing point (130) to the first inlet (112). A regulating valve (134), which is designed for regulating the mixing ratio of two flows mixing at the mixing point (130), as well as a control device, which controls the regulating valve (134) for regulating the mixing ration, are arranged in the pump housing (106). A hydraulic manifold is provided with such a circulation pump assembly.

Disclosed may be an intermediate surface for supporting a small paver, wherein the surface can also be used to exchange heat with the pavers. In one embodiment, the apparatus may be a tray defined by a frame with a lattice for supporting pavers. The tray preferably features a tubing track throughout the lattice to accommodate heat exchange tubing. In operation the tray may be positioned above a pedestal or directly on a subsurface. In embodiment, the tray may be outfitted with insulation and a metal plate so that heat may be exchanged with pedestals via fluid passing through tubing installed throughout the lattice. In a preferred embodiment, the tray features a slot in its corners for receiving a locking disk or locking slider.

A heated flooring assembly includes a base layer having a plurality of studs arranged in a grid pattern, the base layer operable to be coupled to a flooring surface. A screed layer is bonded to an upper surface of the base layer. A length of tubing has an outer surface and an inner surface, the length of tubing operable to carry a fluid that creates a temperature differential between the length of tubing and the screed layer. The length of tubing is retained between at least some of the studs. At least the outer surface of the length of tubing has at least one projection extending outwardly therefrom, the projection increasing a rate at which heat is transferred between the length of tubing and the screed layer as the fluid travels through the length of tubing.

A surface heating conduit (18) includes a fluid-conducting inner pipe (14), a sheathing tube structure (24) surrounding the fluid-conducting inner pipe (14) serving as a thermal shield for protecting the fluid-conducting inner pipe (14) from external heat influences and which is designed such that, when the surface heating conduit (18) is embedded in a layer (12) of hot mastic asphalt that is cooling down from its working temperature, the sheathing tube structure (24) is destroyed thereby protecting the fluid-conducting inner pipe (14) against thermal influences deleterious to the functionality of the inner pipe.
摘要:
A plastic pipe comprising an oxygen-impermeable casing, wherein the casing comprises a barrier layer for oxygen, and an adhesive layer adjacent to the circumferential surface of the pipe and attached to the circumferential surface by an sealed bond, wherein the casing surrounds the circumferential surface on all sides, and wherein the barrier layer is elastic, is substantially impermeable to oxygen and comprises a polyvinyl alcohol, a vinyl alcohol/ethylene copolymer, or polyacrylonitrile. Also disclosed is a process for the production of the pipe and a use of the pipe as a heating pipe.
