Definitions
- the present invention relates to a method of balancing a heating / cooling installation of two-tube water circulation type premises.
- each radiator is provided with a balancing valve whose position makes it possible to control the flow of hot water through it and, consequently, the quantity of heat delivered by it.
- This type of faucet is called a first-level balancing valve because it allows the flow rate to be adjusted as close as possible to one or more radiators.
- second level valves that allow the adjustment of the flow of a set of radiators balanced between them by the first level valves.
- third-level valves that allow the adjustment of the flow of several sets of radiators balanced with each other by the second-level valves.
- a relative flow coefficient has been established for each radiator equal to the ratio of the reference difference to the corrective coefficient of measurement. This corrects the feed rate of a given radiator by multiplying its flow by the inverse of the relative flow coefficient.
- curves are available which express the relative flow variation q% Rn of a valve of a given brand and type as a function of the number of revolutions N of its regulator and this for a constant pressure difference. .
- the object of the present invention is to propose a balancing method that is applicable to first and second level valves in series with transmitters whose hydraulic resistance can be significant and impossible to determine. This is for example the case of non-removable elements, difficult or impossible to measure or calculate due to the frequent absence of distribution plans and internal fouling networks over time, hydraulic resistors such as those of columns or supply lines for transmitters, heating or cooling coils, sanitary circuit loops, etc.)
- This method must also prevent the user the strain of using special valves for measuring flow rates, or the implementation of surveys and complex calculations.
- the present invention thus relates to a method for balancing a heating / cooling installation according to claim 1.
- the document EP 0 795 724 A1 discloses the preamble of this claim.
- a flow control valve must have, in large aperture, an authority of at least 0.5 on average and included, within customary limits, between 0.33 and 0.66, ( authority defined by the ratio of the hydraulic resistance of the large open tap to the sum of the hydraulic resistance of the open tap and that of the circuit for which it is responsible for regulating the flow).
- an authority of at least 0.5 on average and included, within customary limits, between 0.33 and 0.66 authority defined by the ratio of the hydraulic resistance of the large open tap to the sum of the hydraulic resistance of the open tap and that of the circuit for which it is responsible for regulating the flow.
- FIG. 1 a heating installation comprising a hot water supply pipe 1 and a return pipe 3.
- the balancing operation of this installation consists in ensuring that the specific bit rate of each of these sets R n of transmitters is in correspondence with the respective powers.
- thermometers capable of possessing a quasi-inexistent thermal inertia and a capacity to provide accurate and instantaneous measurement, such as infrared thermometers.
- control members of the equilibrium valves RO n associated with each of the sets R n of emitters will preferably be arranged in the half-opening hydraulic position.
- thermometer the temperature ts n of the pipe located at the outlet of each of the sets R n of emitters are measured.
- the coefficient k is taken in a first adjustment cycle to a value close to 1.5. It has indeed been found by the many measurements and tests carried out that if, after a first adjustment, it appears that the quality of the balancing obtained is not satisfactory, a second adjustment cycle can then be carried out in then taking a value of this coefficient of adjustment k weaker, then close to 1.1.
- the installation comprises a hot water supply pipe 1 and a return pipe 3 between which three sets R 1 , R 2 , R 3 of emitters E n are connected in shunt.
- This gives a reference difference of ref 10 ° C.
- the coefficient of authority k 1 is corrected by decreasing it with a value of 0.5 for the low limit.
- the method according to the invention can be implemented manually by carrying out the calculations mentioned above. However it will be easier to control by using a device to guide the user during the process and to automate some of the operations including calculations.
