Definitions
- the present invention relates to a regulation device for a boiler, in particular a central heating boiler.
- a conventional heating system includes a boiler, a three-way valve, two pumps, as well as, of course, the radiators supplied from the boiler.
- the three-way valve distributes the hot water produced at the level of the boiler by sending a quantity more or less hot water to the radiators.
- This valve is controlled by a device that receives temperature information (outside temperature, room temperature, water temperature at boiler outlet, etc.).
- a pump is necessary for the circulation of water to the radiators and another for the return water circulation directly to the boiler.
- boilers called "two-stage" boilers.
- Such a boiler can operate either at 100% of its capacity, or with a predetermined intermediate load. We can thus avoid many ignitions and stops and of the boiler. However, we still have constraints relatively high due to sudden variations in engine speed boiler.
- the object of the present invention is therefore to provide the means for modulating the power of a boiler from a regulation of standard heating for two-stage boilers to avoid variations abrupt revs, upon ignition and then in service mode.
- the device it offers is a regulation for a boiler, comprising a fan driven by a variable speed motor, this device comprising a first contact electric and means for varying the rotation speed of the fan, during the ignition phase of the boiler, between positions stop, walk at a first speed which corresponds to the flow of pre-ventilation, or walking at a second pace which corresponds to ignition rate, the device being characterized in that it comprises a second electrical contact provided to vary, after switching on the boiler and during operation in service mode, the rotation speed of the fan between a first minimum speed X and a second speed MAX maximum, these variations taking place gradually thanks to the means to vary the fan speed when the second contact electric is activated.
- This regulation device makes it possible to maintain the temperature of the water leaving the boiler at a temperature very close to a temperature setpoint. Thanks to the progressive variation of the fan speed, and therefore consequently of the power of the boiler, the constraints by rapid variations in temperature are avoided. In addition, such a device allows to limit the ignition and shutdown of the boiler. These are repeated only in cases where the hot water requirements are low, which does not represents only a small part of the operation of a boiler in general.
- the means provided for acting gradually on the fan speed include a modulator of microprocessor frequency. It is then possible to store in the microprocessor software that controls the fan speed according to data entered beforehand.
- This frequency modulator is advantageously controlled from only from the open or closed state of the electrical contacts.
- the outside temperatures and water produced by the boiler are used as for them for controlling the electrical contacts.
- the regulation according to the invention may include a third electrical contact, also designed to switch the fan from its first to its second pace or vice versa; means for gradually varying the fan speed when the third electrical contact is activated are then also provided, and the speed variation is different according to that it is controlled by one or other of the electrical contacts.
- the present invention also relates to a boiler for central heating which includes a regulating device according to the invention.
- the invention also provides a method of regulation for a boiler comprising a fan driven by a variable speed motor, the boiler being provided with a regulation device comprising a first boiler with a fan driven by a speed motor variable, the boiler being provided with a regulating device comprising a first electrical contact which controls the starting and stopping of the fan and a second electrical contact which allows you to choose the speed of the fan between two predetermined speeds.
- the fan is first blocked by injecting a weak current in the motor, then the fan goes at a speed predetermined pre-ventilation for a predetermined period before switch to ignition speed for a period of time also predetermined, an action on the second contact having no effect on the fan during this entire ignition phase.
- the regulation device is intended for central heating comprising a boiler supplying several radiators.
- the boiler is equipped with a regulation of standard heating for "two-stage" boilers. This regulation then has two electrical contacts.
- a first electrical contact 2 subsequently called on contact 2, controls the start up and shutdown of the boiler. When this on contact 2 is closed, the boiler is switched on while when this on contact 2 is open, the boiler stops.
- a second electrical contact 4 is also provided.
- This second contact 4, subsequently called speed contact 4, allows you to choose between two heating powers. In closed position, the boiler works at full power while in the open position, the boiler operates at an intermediate power.
- the power of the boiler modulates by variation of the air flow sent to the burner.
- a fan sends this air to the burner.
- It is equipped with a variable speed motor controlled by the regulation of heater.
- a frequency modulator with microprocessor is placed between the standard heating control "two gears" and the variable speed motor. Specific software stored in the microprocessor allows the boiler to be controlled from the open or closed state of the two electrical contacts 2, 4 of the heater.
- Figure 1 shows an example of operation of a boiler with a device according to the invention.
- the upper curve 6 shows the temperature T at the boiler outlet as a function of time t
- a curve 8 called setpoint corresponds to the ideal water temperature in boiler outlet.
- This setpoint curve 8 is a function of the temperature outside the room heated by the corresponding heating. Of on either side of this setpoint curve 8, is in dotted lines a curve 10.
- the lower curve 16 of FIG. 1 represents the speed V of the motor driving the boiler fan as a function of time t.
- the time scale is identical for curves 6 and 16. Lines horizontal dotted lines, parallel to the time axis, correspond to four different gears of the engine speed V.
- a first speed X corresponds to the minimum speed below which we cannot go down. This speed corresponds to the minimum air flow necessary for correct operation of the boiler.
- a second speed Y corresponds at the boiler ignition speed.
- the speed Z corresponds to the speed pre-ventilation.
- the MAX speed corresponds to the maximum speed motor rotation.
- the boiler operates in two operating modes different: ignition mode and service mode.
- the modulator switches imperatively in ignition mode. During the course of this cycle, it ignores any change in state of the speed 4 electrical contact. ignition cycle is complete, the modulator switches to service mode.
- Ignition is controlled when the on contact 2 changes from the open position to the closed position.
- the modulator injects a weak current into the motor to block the fan wheel and eliminate any possible free rotation, due for example to the natural draft in the boiler.
- the modulator sends a control voltage to switch the motor to speed Z which corresponds to the pre-ventilation rate of the boiler and remains at this speed for a time T P.
- the modulator then commands the engine to switch to speed Y which corresponds to the ignition rate of the main burner of the boiler and remains in this state for the time T A.
- the boiler ignites during this time T A and the temperature of the water leaving the boiler begins to increase.
- the speed contact 4 When the speed contact 4 is closed, it tends to run the engine at its maximum speed while when in the open position, it tends to run the engine at minimum speed X.
- the speed switch 4 At the end of the ignition time T A , the speed switch 4 is closed. This is explained by the fact that the temperature T is still, at the end of ignition, lower than the set temperature given by curve 8.
- the speed contact 4 remains closed until the temperature T reaches the upper X curve.
- the speed contact 4 While the speed contact 4 is closed, the fan speed gradually increases according to a slope curve a.
- the motor speed increases until the MAX speed is reached or, as is the case in FIG. 1, until the temperature curve 6 reaches the upper dotted curve 10.
- the speed contact opens, commanding a reduction in the motor speed.
- This decrease in speed is also progressive and is also done with a ramp slope a.
- the decrease in fan speed results in a decrease in boiler power and the temperature at the boiler outlet decreases.
- the speed contact 4 remains in the open position until the temperature curve 6 reaches the lower dotted curve 10.
- the speed contact 4 then returns to the closed position.
- Figure 1 shows that thus by alternative openings and closings of the speed contact 4, the temperature curve 6 T follows, without deviating much, the setpoint curve 8.
- the speed of the motor driving the fan of the boiler then oscillates between minimum speed X and maximum speed MAX.
- Figure 2 is equivalent to Figure 1 but for a curve of different setpoint 8.
- the temperature outside temperature is relatively high and therefore the temperature at the outlet of boiler is relatively small.
- the temperature of the water leaving the boiler is such that the temperature curve 6 already reaches the upper dotted line 10 even before the end of the ignition cycle.
- the contact works 2 opens and the fan stops.
- several successive ignition cycles and boiler shutdowns are performed.
- the speed 4 contact closes and we find an operation similar to that described with reference to Figure 1.
- DHW contact 18 Such a regulator with three electrical contacts is used for central heating also including a domestic hot water tank.
- Speed contact 4 and DHW contact 18 each order an increase or decrease the fan speed to move the fan to the maximum speed MAX or minimum X.
- the open or closed state of the contact speed 4 is controlled by a temperature sensor located on the circuit heating supplying the radiators while the open or closed state of the DHW 18 electrical contact is controlled by a probe placed in the circuit supplying the domestic hot water tank.
- the operating mode in FIG. 3 is identical to the operating mode in FIGS. 1 and 2. There is a period 22 of ignition of the boiler, then a period of 24 service followed by a stop of the boiler. We then again have a succession of modes 22, 24 service and boiler shutdown.
- the state of contact on step 2 is preponderant. So regardless of the open state or closed of speed 4 and DHW 18 contacts, when the on contact 2 is open, the boiler stops.
