Definitions
- the main object of the invention is a device for improving the energy balance of a boiler, especially for heating.
- Another object is to allow a user to perform a check on the efficiency of the boiler without resorting to the assistance of a field technician.
- the device for controlling the energy balance of a boiler in
- the boiler comprises
- the electronic circuit is configured to calculate from said information an efficiency parameter of the boiler on the basis of which to drive the combustion operation of the boiler.
- the electronic circuit is configured to compare the processed data with characteristic data of the boiler, e.g. stored during a configuration phase. From the comparison of the data the electronic circuit calculates the two said information.
- the circuit is connected to a data transmitter.
- the electronic circuit can transmit the data detected by the sensors and/or the calculated parameter and/or the state of the boiler to a remote user or electronic receiver.
- the electronic circuit may transmit a warning signal on the state of the boiler.
- the data transmitter may comprise an Internet or Ethernet network card and/or a GSM card and/or a WI-FI or Bluetooth® card.
- Another aspect of the invention is an app loaded or loadable into a mobile phone or smartphone that, when executed, carries out the communication with said electronic circuit to receive a data indicating the state of the boiler and display it on the mobile phone or smartphone display.
- figure 1 schematically illustrates a device as associated with a boiler.
- a device MC serves to improve the energy efficiency of a gas boiler 6, which includes for example:
- a pipe 40 for supplying hot water to the radiators of the heating system and a pipe 46 for the exit of hot water for the sanitary facilities.
- the tube 30 and the tube 40 belong to a same closed water-circuit; the tube 26 and the tube 46 belong to a second open water-circuit, separated from the first one.
- the number of the heated water circuits - closed or open - served by the boiler 6 may in any case vary from what is illustrated.
- the tube 20 generically may inject any gas or fluid to be burned inside the boiler 6, such as for example LPG, diesel, methane or other.
- the invention is not limited to a particular combustible fluid.
- the device MC envisages that on each of the tubes 26, 30, 40, 46 there is mounted respectively a sensor 28, 32, 42, 48 for detecting the flow rate of the water and the temperature of the water flowing in the pipe.
- the sensors 28, 32, 42, 48 e.g. are constituted by a flowmeter, capable of measuring the amount of fluid that runs through the tube, and by a thermocouple for the measurement of the fluid's local temperature.
- a flow sensor 22 is mounted on the gas pipe 20.
- the device MC comprises an electronic circuit 60.
- the output of the sensors 22, 28, 32, 42, 48 is connected to the A/D inputs of the electronic circuit 60, which is able to read the values detected by each sensor.
- the electronic circuit 60 is e.g. a board with a microprocessor programmed to execute the functions described herein. This favors execution of calculations or mathematical functions on the data converted into digital input (a strictly analogical processing is also possible) .
- circuit 60 Associated with - or integrated in - the circuit 60 there is a data memory wherein the circuit 60 can store data in a non-volatile manner.
- means 80 adapted to allow a manual release of the boiler 6, said means 80 being for example constituted by a button which allows the user to restore the normal operation of the boiler 6; and/ or
- means 70 e.g. consisting of a valve, for imposing a reduction of the working temperature of the boiler 6;
- the transmitter 90 capable of sending a signal to a remote user.
- the transmitter 90 may be e.g. a GSM transmitter, an Internet network card, a WI-FI card, or a cabled line; and/or
- a user interface 94 for entering data such as a keyboard or a touch screen.
- the circuit 60 is to be calibrated according to the operating characteristics considered optimal for the boiler 6 by memorizing into it one or more threshold values which represent the desired operating quality of the boiler 6. Below these values, entered e.g. with the interface 94, the circuit 60 will start to operate, e.g. to report the malfunction and the consequent excessive energy consumption or abnormal pollution.
- the value read by the sensors 28, 48 is processed to calculate the difference ⁇ between the two water temperatures at the inlet and outlet of the boiler 6. Similar calculation can be made by the circuit 60 for the heating of the rooms, by considering in this last case the data read by sensors 28 and 42.
- the electronic circuit 60 uses the data obtained from the sensor 22 to calculate the theoretical kilojoules (Kj) that each cubic meter of burned gas should produce to heat the water in the boiler 6.
- the circuit 60 measures a flow of water in the tube 26 and/or 30, and calculates the heat actually transferred from the boiler 6 to the circulating water as:
- VAL1 ⁇ * specific heat of water * liters of water measured by sensor 28 or
- the circuit 60 also calculates the heat theoretically yielded by the boiler 6 to the circulating water, i.e. the theoretical kilojoules (Kj) exchanged with the water, by multiplying the gas flow rate P by an optimal combustion coefficient K,
- the device MC upon signaling an anomaly of efficiency, induces the user to carry out a check of the generator. From the check there can emerge both a necessary system maintenance and a poor quality of the used fuel.
- the circuit 60 is able to simultaneously perform the real time control of all the hydraulic circuits, thus in the illustrated example it is able to recognize which of the circuits is inefficient.
- the tolerated inefficiency threshold or percentage values are distinct for the two hydraulic circuits, e.g. settable by programming the circuit 60 via the interface 94.
- the circuit 60 stores in the memory a history of the data detected by the sensors.
- the circuit 60 is programmed to drive e.g. the display 92 to display the data and to allow consultation and navigation thereof to the user by receiving navigation commands from the interface 94.
- the circuit 60 is programmed to drive e.g. the interface 94 (which is equipped for example with a USB port) to save on a medium the stored sensed and / or calculated data.
- the interface 94 which is equipped for example with a USB port
- the circuit 60 is programmed to remotely send a warning signal when it detects that the boiler 6 works with efficiency below the threshold.
- the warning signal may be sent via the transmitter 90 and/ or displayed on the display 92 and/or generated as an acoustic signal from a sound warner connected to circuit 60.
- the transmitter 90 comprises
- an Internet or Ethernet network card to send a message to the remote user via a more readily accessible format, such as e.g. an e-mail;
- an app can be installed that periodically communicates with the device 60 in order to receive a data indicating the state of the boiler.
