The flow meter 20 is configured to provide the data acquisition device 10 with the flow rate of the thermal transfer fluid flowing through the heating system. The thermometers 18a, 18b are configured to provide the data acquisition device 10 with the temperature of the thermal transfer fluid flowing through the heating system. In the arrangement illustrated and described here, the thermometer 18a is located on the "cold" side of the heat exchanger 14 and the thermometer 18b is located on the "hot" side of the heat exchanger 14. The heat source 16 provides heat to the heat exchanger 14. The energy meter 22 is configured to provide the data acquisition device 10 with the energy consumption of the heat source 16.
The heat source 16 may be a biomass system, a heat pump system, a solar thermal system and a combined heat and power (CHP) system, ground source, or the like. Depending on the type of heat source 16 used, the energy meter 22 may be a gas meter, electricity meter, pyranometer, or the like. Water consumption data may also be provided to the data acquisition device 10 via a water meter.
As explained further below, the data acquisition device 10 is operable to calculate data from at least one measured value and at least one supplied value. In the embodiment illustrated and described here, the data acquisition device 10 is operable to calculate the heat energy produced by the heat exchanger 14 (an example of data, or calculated data).
In order to measure the heat energy produced by the heat exchanger 14, it is necessary to determine how much thermal transfer fluid has passed through the heat exchanger 14 and the change in temperature between input and output therefrom. This is an indication of how much work the heat exchanger 14 has carried out.
In the embodiment illustrated and described here, the at least one measured value includes the data from the flow meter 20 and the thermometers 1 8a, 1 8b. The flow rate from the flow meter 20 and the temperature from the thermometers 1 8a, 1 8b provide the information required to carry out the heat energy calculation. The data acquisition device 10 may be provided with these parameters continuously by the flow meter 20 and the thermometers iSa, lSb.
The heat energy calculated from the flow rate of the thermal transfer fluid and the temperature change between the input and output of the heat exchanger 14 is an approximation of the work carried out by the heat exchanger 14.
In order to improve the accuracy of this calculation the data acquisition device 10 is provided with additional input data (an example of at least one supplied value), which may be a corrected value or modified value of the calculation. Factors that can affect the accuracy of the heat energy calculation of the data acquisition device 10 include the location of the flow meter 20 relative to the heat exchanger 14, the composition of the thermal transfer fluid, the ambient temperature in which the data acquisition device is operating, which may include an indoor temperature and/or an S outdoor temperature. The location of the flow meter 20 with respect to the heat exchanger 14 affects the flow rate determined thereby, e.g. if the flow meter is on the "hot" side of the heat exchanger 14, then the density of the thermal transfer fluid will be lower than if the flow meter is on the cold" side of the heat exchanger 14. This affects the accuracy of the flow rate measured by the flow meter 20. Similarly, the chemical composition of the thermal transfer fluid affects its density and heat capacity. Thermal transfer fluids in heating systems often contain, amongst other things, water, anti-rust chemicals, anti-freeze chemicals, glycol, or ethanol.
Providing the data acquisition device 10 with data on these calculation-influencing parameters improves the accuracy of the data calculated thereby.
The additional input data (an example of at least one supplied value) is provided to the data acquisition device 10 from a remote device 24. As explained further below, the remote device 24 is provided with the additional input data via a manual input from a user, from another value measurement device or another data acquisition device.
In the embodiment illustrated and described here, the remote device 24 is a cloud-based server. The remote device 24 is configured to supply the additional input data to the data acquisition device 10 wirelessly. In the embodiment illustrated and described here, the remote device 24 supplies the additional input data to the data acquisition device 10 via a GSM (Global System for Mobile Communications) system, as illustrated in figure 1. However, it should be appreciated that there a number of ways in which the remote device 24 could wirelessly supply the data acquisition device 10 with the additional input data.
In addition to the above heat energy calculation performed by the data acquisition device 10, the data acquisition device 10 may also carry out one or more additional calculations based on the measured values and the supplied values. Such calculations include coefficient of performance (CoP) calculations of the heat exchanger 14. The data acquisition device uses the calculated heat energy produced by the heat exchanger 14 and compares this to the energy consumed by the heat source 16. The data acquisition device 10 uses the input data from the energy meter 22 as part of this calculation. Because the data acquisition device 10 can continuously monitor the energy consumed by the heat source 16 and can continuously calculate the heat energy produced by the heat exchanger 14, it can produce "real time" coefficient of performance data.
In addition to the above additional input data concerning the density of the thermal transfer fluid and the temperature conditions of the data acquisition device 10, the data acquisition device 10 may also be supplied with operating parameters or specification settings of one or more of the value measurement devices. For example, the data acquisition device 10 may be supplied with information concerning the flow resolution of the flow meter (i.e. "litres per pulse", "cubic feet per pulse" etc.). These operating parameters or specification settings are also supplied to the data acquisition device 10 from the remote device 24. Again, the remote device 24 is provided with the operating parameters or specification settings via a manual input from a user, from another value measurement device or another data acquisition device.
In the embodiment illustrated and described here, the data calculated by the data acquisition device 10 is initially stored on the data logger device 12. The data logger device 12 stores the data on a memory component, which may be a RAM component, ROM component, EEPROM component, a flash memory component, such as an SD card, or USB memory stick.
The data stored on the data logger device 12 is accessible by the remote device 24 and the data logger device 12 can transfer the data to the remote device 24. The data is transferred to the remote device 24 wirelessly. In the embodiment illustrated and described here, the data acquisition device 10 transfers the data to the remote device 24 via a GSM (Global System for Mobile Communications) system, as illustrated in figure 1. However, it should be appreciated that there a number of ways in which the data acquisition device 10 could transfer the data to the remote device 24. As described further below, once the data is transferred to the remote device 24 it can be reviewed, monitored and manipulated in a number of ways.
An example of the data acquisition device 10 in use will now be described.
As described above, in the embodiment illustrated and described here, the data acquisition device 10 is operating as a heat monitoring system, or heat meter. When setting up a heat monitoring system, or heat meter, the physical location of the components often varies with each set up. Often the physical location of the components is not known until the time of the installation of the components or after the installation of the components has been completed. As described above, the location of the components plays an important part in the accuracy of the heat energy calculated by the data acquisition device 10. Also, it is often the case that the physical composition of the thermal transfer fluid is not known in advance and is often only determined by taking a sample of the thermal transfer fluid once the installation is complete. As described above, the physical composition affects the density of the thermal transfer fluid, which affects the accuracy of the heat energy calculated by the data acquisition device 10.
Once the components of the data acquisition device 10 are set up and the flow meter 20, thermometers 18a, 18b, heat exchanger 14 and energy meter 22 are connected to the data logger device 12, the position and flow resolution of the flow meter 20 are recorded, the ambient temperature (which may also include an outdoor temperature measurement) is recorded and the physical composition of the thermal transfer fluid is measured and recorded. The density and heat capacity of the thermal transfer fluid is then determined.
The information relating to the position and flow resolution of the flow meter 20, the ambient temperature (which may also include an outdoor temperature measurement) and the physical composition of the thermal transfer fluid is supplied to the remote device 24. The information may be supplied to the remote device 24 by a user. That is, the information may be supplied to the remote device 24 by a user uploading the information to the cloud-based server. The information may be uploaded to the remote device 24 wirelessly by, for example, via a mobile device, such as a mobile telephone, tablet, or any internet connected/enabled device.
The remote device 24 is then used to supply the additional input data to the data acquisition device 10. A user may operate the remote device 24 to supply the additional input data to the data acquisition device 10. This may be carried out directly or indirectly.
Where the user operates the remote device 24 directly to supply the additional input data to the data acquisition device 10, the remote device 24 may be a PC 25, or the like, and the additional input data is manually entered to the remote device 24 for supplying to the data acquisition device 10. Alternatively, a user may operate the remote device 24 indirectly to supply the additional input data to the data acquisition device 10. This may be carried out when the remote device 24 is located on a server and the server is a web-based, or internet-based, portal that may be accessed by a mobile device 26, such as a mobile telephone, tablet, or an internet connected/enabled device.
The additional input data is supplied to the data acquisition device 10 via a cellular mobile network, as described above.
Once the data acquisition device 10 has been provided with the additional input data it can calculate the heat energy generated by the heat exchanger 14 and/or the coefficient of performance (CoP) of the heat exchanger 14, as described above.
The data acquisition device 10 may be configured to carry out the above-referenced calculations continuously to effect real time" or "live" monitoring of the heat energy generated by the heat exchanger 14 and/or the coefficient of performance (CoP) of the heat exchanger 14. The data acquisition device 10 may generate multiple data sets based on the above-referenced calculations. The data sets may be stored on the data acquisition device 10 and/or the remote device 24. The data sets may be accessed from either the data acquisition device 10 or the remote device 24. Where the data sets are accessed from the remote device 24, this may be carried out by via a PC, mobile device, such as a mobile telephone, tablet, or any web browser enabled device or internet connected device.
The data stored on the remote device 24 may be used to monitor the performance of the heat exchanger 14 and heat source 16. The data stored on the remote device 24 may be archived and stored with the "live' data that users can access at any time to view, download, analyse etc. The data stored on the remote device 24 can be used to monitor any or all of the measurements provided to the data acquisition device 10.
The present invention allows the data acquisition device 10 to be supplied with a value for its calculation from a remote device 24. The remote device 24 can set or modify this value in any way. The data acquisition 10 may therefore be configured remotely by the remote device 24 to allow modification of one or more values of the calculation that the data acquisition device 10 performs. This avoids the time consuming and costly process of having to remove the data acquisition device from its operating environment and send it away for reprogramming.
As described above, with known systems, often none of the parameters are known until the various components are installed together, by which time it is time consuming and difficult to make modifications to the data acquisition device. The present invention offers advantages over such known systems.
In the example given above where the data acquisition device 10 is operating as a heat monitoring system, or heat meter, the data acquisition device 10 facilitates a remote set up by the remote device 24 to allow the device to operate correctly, or more accurately, with the flow meter 20, the physical composition of the thermal transfer fluid and the heat source 16.
This remote configuration of the data acquisition device 10 can be done at any time via web portal, as discussed above. The present invention allows energy readings, power readings, temperature readings (hot and cold) and flow rate readings to be send via GSM, or the like, in a single device. The remote device 24 can also be configured to send alerts to the mobile device of a user if, for example, any reading, or calculation, produces an unwanted result.
Modifications and improvements may be made to the above without departing from the scope of the present invention. For example, although the present invention has been illustrated and described above as operating as a heat monitoring system, or heat meter, of a heating system, it should be appreciated that the data acquisition device may also operate as a cooling system, such as an air conditioning system.
Also, the data acquisition device 10 and/or the data logger device 12 thereof may be configured to take measurement inputs from other value measurement devices, such as additional temperature measurement devices, additional flow rate measurement devices, wind speed measurement devices, additional energy measurement devices, electricity measurement devices, gas measurement devices, water measurement devices, humidity measurement devices, density measurement devices, pressure measurement devices, mass measurement devices, solar radiation measurement devices and calorific value measurement devices.
Furthermore, the data acquisition device 10 is also operable to calculate the heat output, total heat energy, export temperature, return temperature, carbon dioxide offset, and solar radiation produced by the heat exchanger (an example of data, or calculated data).
Also, although the present invention has been illustrated and described above as operating as a heat monitoring system, or heat meter, of a heating system, it should be appreciated that the data acquisition device may also operate in any data acquisition and data monitoring system where it is would be advantageous to be able to remotely configure the data acquisition device to modify, or change in any way, a value that is required to perform a calculation that the data acquisition device performs, or an operating parameter or setting of a value measurement device associated with the data acquisition device.
Furthermore, the data acquisition device of the present invention may also operate as part of a gas meter, where the data acquisition device is operable to calculate the gas usage in real time, by continuously receiving "live" measurements of gas pressure and/or atmospheric pressure and temperature from the remote device so that its gas usage energy calculation is extremely accurate. This avoids the errors that are commonly associated with current gas usage energy calculations that use average gas pressure and temperature readings over a period of time etc. In this arrangement the remote device would by supplying the data acquisition device with real time gas pressure and temperature readings.
