Definitions
- the present invention relates to a cold water supply system in vertical buildings.
- the present invention relates to the field of civil engineering.
- the conventional system adopted by the vast majority of designers of hydraulic installations in vertical buildings in the country uses the upper reservoir, supplied by sets of electropumps, that capture the water from the lower reservoir and elevates it to the upper reservoir through a upward piping, transforming into potential energy to meet demand.
- This method provides unequal pressures for each floor.
- VRP pressure reducing valves
- pressurized pumping which is nothing more than a system that raises directly from the lower reservoir to the pruned ones, operating in the likeness of the conventional system, with reducing valves pressure in the kites, in this case the upper reservoir or is suppressed or reduced to only attend to the fire system when so required. In this case you can introduce the individualized measurement through water meters at the entrance of the consumption unit.
- the set of electro-pumps is actuated by a pressure switch or a pressure transducer that sends a signal to a frequency inverter that drives the whenever the system pressure falls below the desired level, tending to keep all the pressurized piping in with available water at all the inlets of the consumption units
- the advantage of this solution is the energy savings that can reach 50% in relation to the disadvantages are the pressure difference between each floor and pressure drops, when many inputs of the consumption units are requested simultaneously (simultaneity), exceeding the flow capacity of the set of electro-pumps, causing even the interruption of supply
- high-power and high-cost pumping systems are used, in some cases the use of more than one pumping system, each one attending to a specific so as not to exceed 4 kgf / cm 2 , in this case there is no use of a valve pressure reducing valves.
- Another drawback of this solution is the need for a generator in the event of
- VRP pressure regulating valves
- JP2012180834 discloses system and method for water supply in houses or buildings using two control panels which command the entire proposed system. Such panels operate concomitantly, or in order to replace one another as needed, so if the first panel fails a second panel the panel will operate.
- the system is able to feed and manage the consumption of individual lines, but to reach such capacity the system makes use of a power line pump, a fact that increases the cost of the system, affects its reliability.
- JPH048886 discloses an individual building supply system having a lower reservoir and a pump which draws water into several intermediate reservoirs arranged in different stages. The system prevents the difference in feed pressure per floor, however it is necessary of several reservoirs, which need periodic maintenance and cleaning.
- US5032290 discloses a method and system for water supply in order not to deteriorate the equipment which is subject to water. In order to do so, the solution seeks to keep the flow of water constant inside the installation, causing it to circulate all the time. The system is thought to places that can stay a good time without the demand of water that they used to have, for example, a school that in vacation has its water stop stopped. For the operation of the system the upper tank is always in use, still the recirculation of the water does not allow the control of the individual consumption to be realized.
- the present invention is a cold water supply system in vertical buildings using a high-performance, low-cost plug & play kit based on pressurized pumping through a set of electro-pumps (o) controlled by frequency inverter (f), pressure regulation by pressure reducing valves (d) or turbo regenerative pumps (TBRs) (e), managed by small frequency inverters (f).
- the pressure reduction system is equalized and centralized, with centralized flow measurement by water meters (g) that can be analog, digital or wireless, all in the pump house (h) and interconnected and integrated by a manifold (c).
- the control and communication system (w) provides water and energy consumption information and possible nonconformities in the online system.
- the main advantages of the technique are the use of an intelligent pressurized pumping system which sucks the water from the lower reservoir (b) and distributes it directly and exclusively after reducing and equalizing the pressures and measuring the consumption in the manifold (c ) through small diameter semi-flexible tubes (I), which are accommodated in one or more semi-flexible tube rises (m), starting from the pump house (h), with exclusive access to each input of the consumption unit ), with equalized pressure (equal to all floors) and water consumption measurements carried out in the pump house (h) through analogue or digital digital water meters (g).
- the present invention reduces consumption of electricity by directly and instantly raising to the point of consumption the volume of cold water consumed in each unit, avoiding the cost of raising the entire volume to the upper reservoir and then distributing it, wasting about 50% of the energy actually needed. It minimally requires the consumption of water, by at least 30%, by the total speed control in function of the appropriate and controlled pressure.

- the upper reservoir (a) is associated by an upward piping (r) to the set-up of at least one electro-pump of the electro-pump assembly (o) and the manifold (c), wherein the association with the set-up of at least one of the pumps comprises at least one record (n); and
- the present invention aims to solve the problems encountered in the state of the art from the development of a cold water supply system in vertical buildings.
- inventive concept common to all claimed protection contexts is the development of a cold water supply system in vertical buildings.
- FIG 1 shows the conventional system and the flow of water therein.
- Figure 2 shows the proposed system and the water flow therein in normal situation.
- Figure 3 shows the proposed system and the water flow in a situation of simultaneity or lack of energy.
- Figure 4 shows the proposed system with alternative filtering.
- buildings is understood to mean any construction, vertical or horizontal comprising multiple points of consumption and at least one upper reservoir.
- the present application relates to an indirect system with pumping cold water supply in buildings comprising at least one hydrometer for each consumption unit and at least one upper reservoir.
- the present invention provides an indirect system for pumping cold water supply of vertical buildings provided with individual hydrometers (g), at least one lower reservoir (b), at least one upper reservoir (a) which comprises:
- each feed line (I) comprises at least one hydrometer (g);

- the upper (a) and lower (b) reservoirs may comprise one or a plurality of water tanks connected to each other.
- the electropump assembly (o) may comprise an electropump or an association of electropumps, be it the association in parallel or series.

- the lower reservoir (b) feeds the suction line of the pump assembly (o).
- the upper reservoir (a) is associated with the settling of at least one of the pumps by means of an upward pipeline (I).
- the riser pipe (r) has a connection associated with the inlet of the upper reservoir (a) and a by-pass (i) originating from the outlet of the upper reservoir (a), the bypass (i) being controlled by a check valve (j), this connection allows the riser (r) to be used to supply the upper reservoir (a) or the water outlet of the upper reservoir (a). This connection is possible because the system uses the water stored in the upper reservoir (a) only in emergency moments, for example, peaks of consumption or falls of energy.
- the manifold (o), the manifold (c), the pressure reducing valves (d) or regenerative pumps (e), the hydrometers (g) and the control panel (p) are contained in a pump house (h).
