Embodiment Construction

[0066] figure 1 A schematic representation of a water circulation system implementing the method according to the invention is shown. The system comprises a supply line 1 , a return line 2 , two strands 3 connecting the supply line 1 to the return line 2 . The system also comprises a temperature control unit 4, which connects the supply line 1 with the return line 2, whereby in one flow direction water can flow from the supply line 1 via the two strands 3, the return line 2 and the temperature control unit 4 Loop back to supply line 1. The system also includes several consumers 5 arranged along the strand 3 and which can be used to draw water from the circulation system. In each strand 3 a valve 6 is provided, which is arranged in the area of ​​the strand 3 opening into the return line 2 . That is, the valve 6 is arranged in the region of the end of the strand 3 . Using each valve 6, the flow rate of water in the corresponding strand can be varied. In the supply line 1, i...

Abstract

The invention relates to a method for operating a water circulation system comprising the following steps: providing the water circulation system, said system comprising at least one valve (6) and atleast one temperature sensor (60, 61, 62); determining a first temperature (Tl) and a second temperature (T2); determining a period of time (ZD); detecting the water temperature using at least one temperature sensor (60, 61, 62); detecting the opening time during which the at least one valve (6) is at least partially open; at least partially opening the at least one valve (6) if the detected watertemperature exceeds the value of the first temperature (Tl) or if the opening time reaches the period of time (ZD); completely closing the at least one valve (6) if the detected water temperature reaches the value of the second temperature (T2).

Description

technical field [0001] The invention relates to a method for operating a water circulation system, in particular a piped drinking water or industrial water system. Background technique [0002] Methods of operation of water circulation systems are known from the prior art, in which the water temperature must be kept above or below a predetermined temperature in order not to promote the growth of bacteria. The growth of bacteria such as Pseudomonas aeruginosa or Legionella is especially favorable in the temperature range of 20 to 50°C. For hygienic reasons, ie in order to prevent bacterial growth as much as possible, the water temperature should therefore not be kept within this range. For reasons of convenience, ie in order to be able to quickly reach a sufficiently high mixing temperature, the temperature of the hot water is usually kept at 55°C. Since the hot water pipes are not perfectly insulated, heat is continuously dissipated from the pipes into the cooler environme...
