Definitions

the present invention relates to a drinking or service water system with a transfer point from a public supply network and at least one supply line for the supply of water and at least one loop leading to at least one consumer.
This ring line is connected to the supply line via inlet and outlet openings, wherein a cross-sectional constriction is provided in the supply line, preferably between the extraction and threading openings.
the cross-sectional constriction is designed such that when flowing through the supply line in the loop line a flow is effected, due to the Venturi effect.
the drinking or service water system according to the present invention may be a cold or a hot water system.
Modern hot water systems are formed with a circulation, which ensures that hot water heated by a heater is continuously circulated in the lines leading to the consumer, so that hot water is discharged immediately at a consumer water removal and germination of the system, for example by Legionella is avoided.
the circulation prevents the cooling of hot water in the line.
hot water circulation systems the circulation leading away from the consumer and connecting them to the heater or a boiler of the heater with a smaller diameter than the supply line is formed.
a generic drinking or service water system is for example from the DE 10 2006 017 807 known to the present applicant.
several ring lines go from a supply line, which communicates with the interposition of a motor-driven valve with a purge line leading to a discharge point to the dirty water line. With this configuration, it is possible to flush a supply line to dissipate stagnant water there.
a generic drinking or service water system should be specified, which can reliably prevent stagnation in the loop.
a drinking or service water system of the type mentioned is proposed with the present invention, which is characterized by a provided in the loop ring line pump.
a ring line pump leading to the supply line volume flow can be generated in the loop, which leads to a secure and inevitable exchange of the volume in the loop. Accordingly, stagnation can be avoided.
a supply line volume flow measuring device is provided with which the volume flow in the supply line can be measured.
the measuring signal of this supply line volume flow measuring device can be processed in a control device associated with the ring line pump.
the ring line pump can be controlled or regulated accordingly with this preferred embodiment.
volume flow in the supply line and the volume flow in the loop further preferred to provide a ring line volume flow measuring device with which the volume flow in the loop can be measured and their flow measurement signal in the the ring line pump associated control device is processed.
This embodiment serves in particular the purpose to control or regulate the mutual volume flows between the ring line on the one hand and the supply line on the other hand due to the activity of the loop pump.
the inventive drinking or The process water system may have a cross-sectional constriction between the extraction and threading, due to which a pressure difference is generated in the supply line, which leads to a forced flow through the loop at a flow in the supply line.
the volume flow at the threading opening is divided with the present invention into a ring line volume flow and a further volume flow which is not branched off into the ring line and flows in the supply line. These two volume flows unite - if no fluid is removed from the corresponding loop via a connected consumer - in the Ausfädelömie. The flow is caused due to the ring line pump even if no fluid is removed from the system via a consumer at all.
a ring line temperature sensor with the water temperature in the loop can be measured.
the signal of this ring line temperature sensor can be processed in the control device associated with the ring line pump.
the loop pump can be operated temperature controlled.
a rule may be stored in the control device, according to which, especially at higher ambient temperatures, for example in a cold water system, a cyclical flushing of the loop takes place by actuation of the ring line pump. This ensures, for example, in hot summer months at any time that fresh water is present in the loop and germination does not occur there.
a supply line temperature sensor is further provided by which the water temperature in the supply line can be measured and whose signal is processable in the control device associated with the ring line pump.
This supply line temperature sensor can be provided alone or in combination with the ring line temperature sensor.
control device is designed such that the ring line pump is controllable on the basis of the or the control device discontinued signals.
These signals may be the signals to the volumetric flows in the supply and loop lines and / or the temperature values in these two lines.
the information about the volume flow can be made for example by measuring a pressure difference over a given flow path, in particular via a throttle.
a flow measuring element can also be provided in the supply or ring line.
the system comprises a heat source for heating the water, and further comprises a circulation pump provided in the supply line which circulates water contained in the system.
This circulation pump usually comprises a circulation pump control device, which is connected in terms of control with the control device of the ring line pump, so that the two pumps can be operated in a coordinated manner. Accordingly, the two pumps can be operated so that their effects mutually reinforce each other.
