  • a domestic hot water (DHW) system is used to provide warm or hot water on demand in a building.
  • a block diagram of a part of a common domestic hot water system In use, cold water from a mains supply enters the system via a stopcock, a filter, and a pressure-limiting valve. This protects the components of the system from damage, including contaminants, and permits the system to be isolated, where necessary.
  • a branch connection directs cold water to one or more cold water connection in the system, such as a cold tap or the like. The water then passes through a non-return valve. The cold water is subsequently directed through an inlet port into an enclosed container or vessel, generally known as a cylinder, though the vessel is not limited to a cylindrical shape. The cold water typically enters at the base of the cylinder though the water may enter at another location in the cylinder, where necessary.
  • a common form of cylinder comprises a generally cylindrical body with domed or hemispherical ends welded in place.
  • the cylinders are required to be manufactured from a corrosion resistant material and, due to the increasing pressures within the cylinders, from a material capable of withstanding the said pressures.
  • Cylinders have traditionally been constructed from Copper.
  • manufacturers more recently have manufactured cylinders from steel, and in particular, stainless steel.
  • Even more recently, cylinders have been manufactured from a specialist stainless named Duplex.
  • Duplex offers a material with higher corrosion resistance, higher strength (which allows it to be manufactured from thinner material) and is also quicker and easier to weld than other stainless and copper materials.
  • Air will often be contained within the system and it is generally desirable to remove this air from the active system to prevent damage to the system components and to improve the working efficiency of the system.
  • a pressure vessel may be connected to the system at a level higher than the cylinder such that, due to the relative densities of the air and the water, the air will rise into the pressure vessel.
  • the cylinder also comprises a heat exchanger which may be in the form of a coil of pipe.
  • the cylinder may also comprise one or more additional heating elements in the form of an immersion heater or the like.
  • the heat exchanger coil is connected to a boiler such that hot water is directed from the boiler into and through the coil pipe.
  • the circuit or loop containing the boiler and the heat exchanger coil is typically known as the primary circuit.
  • the coil is directly heated by water from the primary circuit, which in turn indirectly transfers heat to the fluid in the cylinder.
  • the water in the cylinder is known as secondary water.
  • warm water within the cylinder expands and is directed through a cylinder outlet to supply hot connections in the system such as a hot tap or the like.

  • the second face may be adapted to initially define a shaped surface, for example, but not exclusively, a dome, elliptical dome, or other curved surface.
  • the fluid force may be adapted to deflect or deform the second face to maintain the seal between the piston member and the vessel.
  • the force may comprise a reaction force produced in response to compression of fluid in the second vessel portion.
  • the first vessel portion may be adapted to receive and contain water.
  • the first vessel portion may be adapted to receive cold water to be heated.
  • the second vessel portion may be adapted to receive and contain a fluid.
  • the second vessel portion may be adapted to receive and contain air.
  • the present invention thus provides a fluid container comprising a vessel divided into two portions by a piston member.
  • the vessel portions can be sealed relative to each other.
  • the container does not require a separate vessel for containing a fluid, for example, air which may have become trapped in the system.
  • the piston member defines an interface between a volume of air in the vessel and a volume of water in the vessel.
  • the piston member may comprise one or more apertures for permitting transfer of fluid through the piston member.
  • the piston member may further comprise a membrane adapted for location over the one or more aperture.
  • the membrane may be adapted to permit transfer of one of the fluids and not the other fluid.
  • the membrane may also be adapted to permit fluid transfer through the membrane in one direction only. Thus, air in the first vessel portion may be permitted to travel through the membrane into the second vessel portion but is prevented from returning through the membrane into the first vessel portion.

  • the second piston member face is adapted to deflect to force the seal member into sealing and/or enhanced sealing engagement with the vessel.

Abstract

L'invention concerne un réceptacle de fluide amélioré pour utilisation dans un système d'eau chaude domestique. Le réceptacle de fluide comprend un récipient fermé (10) pour le stockage de fluide, qui est fabriqué en aluminium. Deux ou plusieurs pièces (12, 14, 16)sont soudées ensemble pour former le récipient fermé. Les propriétés mécaniques du récipient fermé sont normalisées par un procédé de recuit. Une entrée de fluide (18)est formée dans le récipient fermé en ajustant par pression un tube à l'intérieur d'un orifice. Le tube est scellé dans l'orifice en utilisant une bague d'étanchéité en caoutchouc, plutôt que par soudage, de sorte que l'expansion ou la contraction du récipient en aluminium fermé n'affecte pas le joint.
