Definitions
- the present invention relates to a balancing and control valve for a heating or cooling system and a method for the hydraulic balancing of such a balancing and control valve in a strand of a heating or cooling system.
- Adjustment throttles or balancing valves which are upstream or downstream of the actual control valves, adjusted so that those specified by the planner
- Flow values can be achieved in each strand.
- the speed of the pump should be set as low as possible, but high enough to all required
- Resistance eg an orifice plate or a heat exchanger.
- Alternative to Differential pressure measurement can also be a mobile ultrasonic flowmeter can be used, which can be mounted on the outside of the piping.
- EP 0 301 568 discloses an auto-calibration method for a control valve in which the effective travel of the valve is detected and the control range is limited to this effective travel.
- the effective travel is defined as the range of the total travel between 5% and 95% of the maximum flow. This document is not concerned with the task of hydraulic balancing.
- the invention is now based on the insight that said prior art hydraulic balance adjustment is made only with open control valves to determine the minimum necessary pump delivery required at full load to achieve all required flows in the individual strands .
- the disadvantage then arises that in strands with already throttled balancing valve (balancing valve) a larger part of the control range of the control valve is lost. If the balancing valve is partially closed, namely the overall characteristic (ky - flow characteristic) of the strand at a larger opening of the control valve, ie in its upper control range, flattened. In contrast, the overall characteristic is steeper with smaller opening of the control valve, ie in its lower region.
- variable loop gain actually requires variable control parameters. This makes the tuning of the controller difficult, especially since variable parameters are usually not provided in the controllers used.
- Restriction is also communicated to the valve control, so that the signal range can be automatically mapped to the new setting range.
- a method for hydraulic balancing a balancing and Regulating valve in a strand of a heating or cooling system is used when such a balancing and control valve and a load is provided.
- a strand of the heating or cooling system is flowed through by a medium.
- a control value for the balancing and control valve is determined, in which a predetermined flow value of the medium, which is less than the maximum flow value, is achieved in the strand.
- This control value is defined and set as "maximum control value.”
- the control range of the trim and control valve is then defined as the range between the set "maximum control value" and the position with the trim and control valve closed.
- the original signal control range of the balancing and control valve is then mapped to the newly defined setting range. This results in full dynamics with reduced maximum control value.
- the valve characteristic is an equal percentage characteristic in order to produce a linear dependence in interaction with a connected heat exchanger. Due to the restriction of the setting range, an equal percentage valve characteristic at 100% setting range is also in the balanced state, ie with a smaller setting range, for example 60%, equal to the percentage. This applies over the largest area of the restricted setting range.
- a predetermined lower control range can be designed linear in order to ensure better control of the small valve openings.
- This division of the control range over a continuously differentiable transition allows the combination of the advantageous equal percentage valve characteristic in the large opening area to avoid a flattening of the slope at high control deflections, with the linear flat characteristic in a predetermined lower control range.
- the setting of the "maximum control value" which can be set in the form of a limiting angle, for example, can be done manually directly on the actuator, or electrically via the control signal, which is also used in control mode.
- Saving the "maximum control value”, ie the determined and set position of the valve as a new maximum value, can be done by pressing a key directly on the drive, or electronically by sending a bus command This command can be either from a service tool, or be sent from the building management system.
- Figure 1 shows a diagram which schematically shows a characteristic of a conventional control valve, which is connected in series with a balancing valve, and a characteristic of a balancing and control valve according to the invention.
- FIG. 2 shows a diagram which schematically shows a characteristic curve of a heat exchanger as a load, a characteristic curve of a balancing and regulating valve according to the invention and the overall characteristic curve of a line. Ways to carry out the invention
- FIG. 1 shows a schematic of a characteristic curve 10 of a conventional control valve, which is connected in series with a balancing valve, and a characteristic curve 20 of an inventive balancing and control valve.
- the pitch 11 of the characteristic curve 10 of the conventional control valve is much steeper in the lower control range, ie at values of, for example, 10 to 20%, than the pitch 21 of the characteristic curve 20 of a balancing and control valve according to the invention in the range between 0% and 30%.
- This allows a more accurate control in the lower control range and thus prevents larger control vibrations.
- the slope 11 or 21 is still connected to a region 13 without incline, also called dead angle or dead zone, here at 0% to 10%.
- the slope 12 of the characteristic curve 10 of the conventional control valve in the upper control range here very flattening from 80% of the control range and in, for example, goes against a percentage kv of 25%, by the pros or Downstream balancing valve is specified as the maximum value.
- the characteristic curve 20 of a balancing and regulating valve for this method and apparatus is equal to percentage.
- the same input variable changes cause the same percentage output variable changes over the entire cycle Control range.
- Figure 2 shows a diagram which schematically shows a characteristic of a heat exchanger 30 as a load, a characteristic 20 of a balancing and control valve according to the invention and the overall characteristic curve 40 of a strand.
- the exactly opposite designed characteristic curve 30 of a heat exchanger connected as a load can be compensated, so that then an overall characteristic curve 40 results, which is substantially linear.
- control characteristic 40 of a string remains substantially linear, or may be viewed as such by a control unit.
- the equal-percentage characteristic 20 addressed here is modified.
- D abei is the expression of the quotient of the opening angle ⁇ to the set maximum opening angle ⁇ -mo. That is, the value shown in FIG Position signal is plotted on the abscissa; and kvioo the flow rate at fully open maximum opening angle.
- n g ⁇ (English n ⁇ p ) is a measure of how much the curve is curved. Since exponential functions never pass through the zero point, this definition of the characteristic in the lower region 21 is replaced linearly. The transition from the linear to the exponential part is continuously differentiable and it is given by the reciprocal of n g ⁇ .
- n g 4.5.
- Cooling system is then constructed as follows on the components of the system.
- a heating or cooling system comprises at least one pump and a plurality of strands, each having a balancing and control valve and a load, wherein the valve and load are connected in series one behind the other.
- the load is usually a heat exchanger.
- a maximum control value is then set for each of the trim and control valves so that predetermined flow values in each leg be achieved.
- the adjustment range of each balancing and control valve is defined as the range between the set maximum control value and the position with the balancing and control valve closed. Then in the control circuit of the heating or cooling system of the signal control range of each balancing and control valve is mapped to the newly defined setting range, so that again the full signal control width of 100% is available, which is applied to a reduced control range.
- the maximum control values of the individual balancing and control valves can be stored, which then after this storage as setting signals to the balancing and
- balancing and control valves and elements acting as a load are advantageously used, each having its own characteristic, so that the resulting from load and balancing and control valve total characteristic of a strand is substantially linear.
- the load characteristic usually has a shape like the characteristic curve 30 in FIG. 2, it is advantageous that adjustment and control valves are used which have an equal percentage valve characteristic curve and there again preferably a characteristic curve with an n g of 4.5.
- the balancing and control valve according to an embodiment of the invention can also be useful on its own. It is then still set a maximum control value for this balancing and control valve; this adjustment being made by an adjustment knob, for example potentiometrically.
- the maximum control value is not just a stop, but a maximum adjustable angle or other manipulated variable of the valve, so that a predetermined maximum flow value is achieved in the strand of this valve.
- This maximum value can also be stored in a, for example non-volatile, memory of a control and regulating circuit of the valve.
- the setting range in this control and regulating circuit is defined as the range between the set maximum setting value and the position when the balancing and regulating valve is closed. Then, in the control circuit of the heating or cooling system, the signal control range of this balancing and control valve can continue to be addressed over the full signal control width of 100%, which is then actually applied to a reduced control range in the valve.
- Signal control range is understood to mean the range of input signals (digital or analog) for the balancing and control valve with which a control unit can respond to this valve to a maximum, which usually corresponds to values between 0% and maximum 100% opening of the valve. In the invention, this maximum signal control range just scaled to the full reduced adjustment range of the balancing and control valve responsive and there is no interval of the signal control range, which is lost.
- such a balancing and control valve can work autonomously in a train when it is acted upon by a conventional control unit of a heating or cooling system with a drive signal between 0 and 100%. But it can also work with a control unit of a heating or cooling system according to another proceedingssbeispiei of the invention, in which the balancing and control valve does not itself knows or stores a maximum threshold, but in this control unit these maximum control values are stored and then the drive signal for a balancing and control valve just does not have a signal value between 0 and 100% but covers only a predetermined by the maximum control value range of, but then with a signal value resolution of 100%.
