Abstract

The heat consumption metering method records the date, the month, the day of the week and/or the time and the temperature difference between the feed and return water temperatures for the radiators (1) and/or the flow rate through the radiators, with the detected values recorded in respective storage locations for different tariff ranges. An Independent claim is also included for a heat consumption metering device.

Description

The invention relates to a method for recording values for the heat consumers averaging for heating systems with several consumption points. - The invention relates to fer ner an apparatus for performing the method.

Nowadays it is a rule that in multi-family houses the heating costs correspond to that assign individual heat consumption. Except for the earlier evaporation Nowadays, tubes also have electronic methods for recording the heat need in such heating systems. The consumption-dependent heating costs are included previously proportional to heat consumption.

One problem, however, is ineffective customers who are very concerned with their heat requirements cover high flow rates but low temperature spread. The energy supplier is then forced to install larger pipes and stronger pumps without ever doing so however, a higher energy price for the heating energy provided is redeemed can. It is also expensive for the energy supplier, for example for all parties the high amount of energy in the midday hours and in the early evening hours to make available, while the heat demand is only low at night and therefore capacities are free.  

Based on this, the object of the invention is an improved one Method for recording values for heat consumption determination in heating systems create with multiple consumption points, in particular as a basis for a fair res method of calculating heating costs; in addition, a device for through management of the process.

As a technical solution, the invention proposes that as a value the date and / or the (date) period and / or the month and / or the Day of the week and / or the time and / or the temperature difference of the heating water between the inlet and outlet in the radiator and / or the flow of the heating water is / are used in the radiator and / or the flow of energy and that the detected / n Values assigned to predetermined value ranges and assigned in these value ranges nten memory locations are saved.

The method according to the invention creates the basis for the classification of different acceptance behavior in tariff and billing structures, for example in the subdivision of the acceptance behavior into a low tariff, normal tariff and a special or high tariff. As a result, for example, the aforementioned ineffective customers who cover their heat requirements with very high flow rates but lower temperature spreads are more financially burdened than uncritical customers. The energy supplier can get a higher energy price from these ineffective customers and then have the option of installing larger pipes and stronger pumps. This billing according to tariffs therefore creates more justice overall. The basic principle of this tariff model is therefore to stagger the cost of heat consumption in heating systems depending on various parameters or criteria. The following values or data are available as criteria for the tariff classification: the date, a (date) period, the month (January to December), the weekday (Monday to Sunday) and the time (0:00 to 24: 00:00) also the instantaneous temperature difference of the heating water between the inlet and outlet in the radiator (measured in K), the instantaneous flow of the heating water in the radiator (measured in m ³ / h) and finally the instantaneous energy flow in the radiator (measured in kW), whereby this momentary energy flow combines the instantaneous temperature difference and the instantaneous flow. According to the invention, the method is technically realized by measuring the criterion values and assigning predefined value ranges in which the values are then stored. The sum of the values in these value ranges can then be used to calculate the costs.

At least two value ranges are preferably combined with one another and one Allocated storage space. For example, the days of the week and the temperature differences can be combined with each other, with special rates for Saturday / Sunday. Unless different value ranges of different values are not combined The time or the current energy can be used as a criterion, for example pouring can be used. The examples can be expanded and varied as required.

A further development suggests that the / the values recorded and then in the ordered storage space is / are saved. This is one of the procedural run continuous determination of the measured values and subsequent grouping the These measured values in the different value ranges ("subjects") created. Any reading the "valency" is assigned immediately thereafter, so that a con control of the heating costs already achieved is possible.

The values are preferably recorded at regular time intervals. It is conceivable with for example, the data update every 36 seconds, so that a high accuracy and timeliness of the measured values is guaranteed. Of course you can both shorter and longer time intervals than the 36 given purely by way of example Seconds can be selected.

As a technical solution, the invention as a device for performing the Method an arithmetic unit for recording the values and one to the arithmetic unit lockable module with a memory with different storage locations gene.

This creates a technically simple possibility to implement the invention Realize procedures. The basic idea is to create an existing Re Chenwerk continue to use the values and to this calculator to connect a special tariff module for example via an optical interface, whereby In this so-called tariff module, the values from the arithmetic unit are correspondingly included in the "Subjects" are grouped. Via the (optical) interface, everyone in the calculator can existing data can be queried and processed by the module. The module works as an independent unit. It is a memory module with its own microprocessor and calendar as well as real time clock with programmable summer / Winter time changeover. For example, the tariff module reads the current every 36 seconds ellen data from the arithmetic unit and "sorts" the values - depending on the program tion - into different "subjects". In total, the module can store 12 such memory locations  of which 6 memory locations are permanently occupied and 6 memory locations are freely programmable are. The device data, the device values, for example, can be used as fixed storage locations (Sum of the thermal energy, the flow and the resting phase), the devices errors as well as the maximum values for current energy flow, temperature difference and current flow rate can be used. The module can be programmed using PC software via the optical interface. The data reading can also via the optical interface of the module or alternatively via an infrared Interface according to ZVEI. Remote reading via a telephone modem is on Optical interface set possible. After all, there is also a self-reading at one Optical interface can be set using a special readout module. Is too it is finally conceivable to drive a test mode in which the tariff module adds up the sum compares the storage locations with the total display of thermal energy and or detects and displays multiple amounts of energy. After all, it was invented according tariff module the advantage that it is not subject to the obligation to calibrate, since the Mes solutions take place within the arithmetic unit and are not impaired.

Finally, a further development of the device for implementation suggests tion of the method that the module is programmable with its memory locations, the storage locations optionally and if necessary, the value ranges of the value are orderable. As previously mentioned, the module can be programmed via the optical interface of the module, which is connected to the RS 232 Interface of a PC is connected.

A system according to the invention for recording values for the heat consumption determination in heating systems with multiple consumption points is based on the purely schematic described drawing.

Two radiators 1 can be seen in the drawing. The heating system are measuring devices 2 for example for measuring the instantaneous energy flow and for measuring the temperature difference of the heating water between the inlet and outlet net. These measuring devices 2 are connected to an arithmetic unit 3 . A so-called (tariff) module 4 is in turn connected to this arithmetic unit 3 . The specialty here is that the arithmetic unit 3 already has a corresponding interface from the outset, so that this creates the possibility of retrofitting with the (tariff) module 4 according to the invention. This means that the arithmetic unit 3 can currently be retrofitted with this (tariff) module 4 , the arithmetic unit 3 itself not requiring any modification in order to be able to use it in combination with the (tariff) module 4 . For example, the (tariff) module 4 can be screwed onto the arithmetic unit 3 .

The operation of this system for recording values for heat consumption determination in heating systems is as follows:
The arithmetic unit 3 measures the current energy flow (z. B. 2.5 kW) and the temperature difference of the heating water between the inlet and outlet (z. B. 72 K). As soon as new consumption data are made available by the arithmetic unit 3 , these consumption data are transferred to the (tariff) module 4 via the optical interface of the arithmetic unit 3 . This can take place every 36 seconds, for example, so that a high sampling rate with associated high measuring accuracy is given.

The (tariff) module 4 checks the measured values received by the arithmetic unit 3 on the basis of the pre-programmed criteria. In the present exemplary embodiment, the day of the week and the temperature of the heating water between the inlet and the outlet are used as criteria. A total of six value range pairs are programmed in the (tariff) module 4 and assigned to memories 1 to 6, as can be seen in the drawing. In the illustrated embodiment, the weekday may be a Monday and the temperature difference may be 72 K. This means that after the criteria have been checked, the measured value is stored (accumulated) in memory 1 (discount tariff). If the temperature difference were 25 K instead, the measured value would be stored in memory 5 (special tariff).

The data stored in the (tariff) module 4 can be read out by connecting a PC and evaluated for further processing, especially for invoicing.
