Abstract
A cold water distribution system for a multi-storey building has a lower accumulator provided in the building on a lower floor thereof and an upper accumulator provided on an upper floor of the building. A water inlet pipe leads from an external mains water supply into the building and is connected to the lower accumulator through an inlet non-return valve. A riser leads from the lower accumulator to the upper accumulator and is provided with respective lower and upper non-return valves adjacent the outlet from the lower accumulator and the inlet to the upper accumulator. An electrically-driven pump is provided in the riser to pump water to the upper accumulator and a water distribution pipe is connected to the upper accumulator for supplying cold water to at least the upper floor of the building.
Claims19
A method of supplying cold water to a multi-storey building having lower and upper floors, which method comprises:
- supplying water through a water inlet pipe leading into the building from a mains water supply external of the building;
- supplying the water from the inlet pipe though an inlet non-return valve to a lower accumulator provided in the building on a lower floor thereof, the inlet non-return valve being arranged adjacent the lower accumulator;
- pumping water from the lower accumulator with an electrically-operated pump into a riser leading from the lower accumulator to an upper accumulator provided on an upper floor of the building, there being respective lower and upper non-return valves disposed in the riser adjacent the outlet from the lower accumulator and the inlet to the upper accumulator;
- and
- supplying cold water from the upper accumulator to a water distribution pipe to distribute cold water to at least the upper floor of the building.
A cold water supply system for a multi-storey building having lower and upper floors and there being an external mains water supply for the building, which system comprises:
- a water inlet pipe leading into the building from said external mains water supply;
- a lower accumulator provided in the building on a lower floor thereof;
- an inlet non-return valve arranged adjacent the lower accumulator and said inlet pipe being connected to the lower accumulator through said non-return valve;
- an upper accumulator provided on an upper floor of the building;
- a riser leading from the lower accumulator to the upper accumulator;
- a lower non-return valve and an upper non-return valve disposed in said riser respectively adjacent the outlet from the lower accumulator and adjacent the inlet to the upper accumulator;
- a water distribution pipe connected to the upper accumulator for supplying cold water to at least the upper floor of the building;
- and
- an electrically-driven pump having a water inlet and a water outlet and arranged in the riser to pump water to the upper accumulator.
