摘要： A method and a system for saving liquid and thermal energy, where a centrally located source of liquid is connected via separate feeding conduits to a plurality of liquid tap units. Each feeding conduit (FC1) is connected to a dampening chamber (D1) via a passage (OP1) containing an inlet (INi) to a liquid valve (VI) adapted to open when liquid reaches the inlet, so that liquid will flow from the feeding conduit to the associated liquid tap unit (LT1). Each feeding conduit is also connected to an evacuation pump (EP) via an evacuation valve (EV), which pump empties the feeding conduit after supply of the respective tap unit.

摘要： A dampening valve unit (40) for use in a liquid distribution system, the liquid distribution system having a centrally located liquid source connected via a separate feeding conduit to a liquid tap unit. In the liquid distribution system each feeding conduit is evacuated of liquid when an associated tap unit is closed and refilled with liquid when the tap unit is opened. The unit (40) comprises a dampening chamber (26) which is connectable to said feeding conduit, and a liquid stop valve unit (1′, 18), connectable at an inlet end (22) thereof, to said associated feeding conduit and which has an outlet end (24) being connectable in use to said associated liquid tap unit. Said dampening chamber (26) is adapted to collect gas and is connectable to said associated feeding conduit via a passage (23) which is located at said inlet end (22) of said liquid stop valve unit (1′, 18). The dampening valve unit (40) and the feeding conduit in use form a closed system separated from the ambient air.

摘要： A liquid distribution unit, for use in a liquid distribution system designed for saving liquid and thermal energy. It comprises and inlet manifold (FL) with a number of branch connections (CI, C2) for connection, in use, with associated feeding conduits (FC1, FC2) and liquid tap units. The inlet manifold device has an inlet end (IE) for joint connection, in use, with a liquid source (LS). Each branch connection has an associated control valve (CV1, CV2) for selective communication, in use, between the liquid source and an associated one of the feeding conduits. Each branch connection is also provided with an additional branch connection located downstream in relation to the associated control valve, as seen when the liquid is refilled into the feeding conduit, and having an associated, separate liquid evacuation valve (EV1, EV2) and an outlet end (OE1, OE2). The outlet ends of the additional branch connections are jointly connectable to an evacuation liquid pump (EP).

摘要： A method and a fluid tap device for retaining the temperature of a liquid, in particular hot water, in a liquid distribution system having at least one liquid conduit extending from a liquid source to a liquid tap. After completion of a tapping operation and replacing the liquid with gas in the liquid conduit, the refilling of liquid in the liquid conduit is performed in three steps: - a first step, initiated by said liquid tap being activated, the activation of the liquid tap causing a change of a physical variable which propagates backwards along said liquid conduit and initiates a second step, - said second step involving refilling the liquid conduit with liquid from said liquid source, while permitting remaining gas to escape via a gas passage being separate from a liquid passage in said liquid tap, and - a third step, initiated when the liquid reaches said liquid tap, involving opening of said liquid passage and permitting the liquid to flow out via said liquid passage and through said liquid tap.

摘要： There is disclosed a method for substantially retaining the temperature of a liquid in a liquid distribution system having at least one liquid conduit (7, 8) extending from a liquid source (1, 2, 3) to a liquid tap (9, 10). When a tapping operation is finished, the liquid is evacuated from the liquid conduit, and a gas is brought into the liquid conduit in order to replace the liquid therein and cause the liquid to flow backwards to the liquid source. When liquid is to be tapped from the liquid tap, the gas is evacuated from the liquid conduit.
