    The invention relates to a method for detecting a heat utilization according to the preamble of claim 1 and a device for detecting a heat utilization in a room according to the preamble of claim 5.
    When dividing the heating costs of a detection unit, such as a building, the detection of heat use by means of heat detection devices, commonly referred to as electronic heat cost allocators, which detects the heat flow from a radiator in a space heated by this space by means of two sensors, a radiator sensor, which detect the radiator temperature and a room sensor designed to detect the room temperature. In this case, the difference between the average surface temperature of the radiator and the room temperature is determined at each radiator and integrated with their duration of action and thus formed a heat utilization value per radiator. The different size and design of the radiators is taken into account by corresponding radiator-specific characteristic values or correction factors. The proportion of heat utilization values added per apartment to the total of all heat utilization values of a detection unit (building or object) corresponds to the proportion of energy consumption of the respective dwelling. For the proportionate determination of the heating costs, these are usually split into a fixed and a variable part and the variable part is allocated according to the aforementioned proportion of the heat detection values of the respective apartment.
    The problem is often that can set depending on housing situation situations in which despite turned off radiator in certain living spaces temperatures of more than a given the usual housing use of the room permitting temperature, for example, 22 ° C, achieved because heat from neighboring apartments, overheated Staircase or staircase or especially in old buildings free, not isolated by the leading rooms risers of the heating system is related. This can lead to that for such rooms or apartments of the manner described above
    Measurement of the heating costs of the distributor is low and does not represent the actual heat use of a room, which can subsequently lead to a small proportion of the attributable variable part of the energy consumption and ultimately to low heating costs for a residential unit.
    DE 10 2008 036 031 B3 shows a method for operating an electronic heat cost allocator in a room with a radiator, wherein a radiator and a room temperature are determined, it is determined whether a count operation of the electronic heat cost allocator takes place by display or consumption values depending at least the radiator temperature are reported and a temporal change of at least one of the two specific temperatures is taken into account.
    DE 10 2005 027 820 B3 shows a method for operating an electronic heat cost allocator, in which in particular is repeatedly checked whether a real heating state or a state of warming is present, in the latter case an auxiliary counter is counted up, while this on detection of a real heating state to zero is set and a display progress is performed. Furthermore, upon detection of a cooling-down phase of the room temperature, a state of external heating of the auxiliary counters is to be counted down, and only when the value of zero has been reached, is a display step to be carried out, wherein the progress of the display includes counting-genuine consumption.
    DE 196 40 900 A1 shows an electrical heat cost allocator with a radiator sensor for determining the radiator surface temperature and a recirculation sensor on the device for determining the circulating air temperature on the housing of the electrical heat cost allocator and with an evaluation of the aforementioned measured values serving circuit arrangement with at least one analog-to-digital converter and a microcomputer as well as with a device for avoiding measurement errors due to the influence of external heat sources that can be detected with the help of the circulating air sensor. This electric heat cost allocator is further configured such that below a festluft at the circulating air temperature determined circulating air temperature of the electrical heat cost allocator operates as a so-called Zweifühlgerät with radiator sensor and recirculation sensor, wherein a rating of the measuring operations only takes place if certain value relationships between the determined temperatures are met and that above a determined at the recirculating air sensor determined circulating air temperature of the electrical heat cost allocator acts as a so-called Einfühlergerät with a radiator sensor and with a fixed value in the circuit input circulating air temperature.
    Finally, DE 196 41 324 A1 shows an electrical heat cost allocator, which has only one temperature sensor, namely the radiator sensor has. To suppress the effects of extraneous heat sources, such as solar radiation, secondary heating, manipulation or the like, data serving as decision criteria are given to the circuit arrangement, whereby a decision is made by appropriate algorithmic links of these data in conjunction with the thermal measurements of the radiator sensor, whether the measurement process on Heat cost allocator is to be evaluated as a real heating process or not.
    The invention is therefore based on the object to provide a method and a device for heat utilization detection, in which also heat utilization can be detected in the above-mentioned cases.
    According to the invention, the object is achieved by a method of the type mentioned, which has the characterizing features of claim 1. Furthermore, the object is achieved with a device of the type mentioned, having the characterizing features of claim 5.
    According to the invention within a heating period, which may be statically predetermined, or can be determined dynamically, the times determined in which the radiator was not in operation, its radiator temperature was thus not above the temperature of the associated room, the latter still one predetermined value in use (Wohlfühlwert, for example, 22 ° C) has exceeded (the value can be adjusted in a suitable manner). The radiator temperature sensor measures the surface temperature of the radiator and the
    Room sensor the temperature of the room. Both temperatures are equal, taking into account tolerances, but the room temperature above a predetermined value, such as 22 ° C., determines the time span of this condition. By summing up the periods or intervals during a heating or accounting period results in accumulated time value indicating how long during a heating or accounting period, a temperature prevailed in the respective room, the predetermined value, such as just 22X, exceeded without the radiator was in operation. The time value thus detected, taking account of a detection factor, enables the determination of a fictive heat consumption value and its consideration in the calculation of the proportion of heat utilization in a room and in total for a dwelling on an entire detection unit, such as an object or a building, which does not have the respective radiator in each room and thus the apartments was supplied. Accordingly, this proportion can be quantified in terms of cost in the manner outlined by the above-mentioned detection factor and allocated according to a separate calculation key to those apartments which have benefited from other related heat (neighboring apartments, corridors, continuous heating pipes). While it may be provided in a preferred embodiment that the determination of the heat is used in a given period of use or heating, provides a highly preferred embodiment, that the determination of heat utilization then takes place when detected by the radiator temperature sensor at least one other radiator radiator temperature the same detection unit as a building above which room temperature is measured by an associated room temperature sensor. In the latter case, the determination of the use of heat takes place in the rooms in which the radiator temperature does not deviate from the room temperature, as long as, in at least one other room, the heat utilization is determined by the difference between the radiator and room temperature. In the latter determination, this is done taking account of temperature correction factors and a factor attributable to heat flow.
    In a preferred manner, it can furthermore be provided that, when a room is heated by another switched-on radiator, a switched-off radiator assigned to the same room, in which no temperature difference between radiator and room temperature is accordingly given, is assigned no fictitious heating power.
    The device according to the invention is designed in a corresponding manner.
    Further advantages and features of the invention will become apparent from the claims and from the following description in which a preferred embodiment of the invention with reference to the drawings is explained in detail. Showing:
    1 shows a simplified schematic block diagram of a device according to the invention for detecting a heat utilization; and FIG. 2 shows the method sequence in a method according to the invention for detecting the heat utilization.
    The invention includes a first heat utilization detection unit 1, commonly referred to as an electronic heat cost allocator, on a first heater 1.1. The heating cost allocator 1 has a first sensor, a radiator sensor 1.2, which stands for the most accurate detection of the temperature of the radiator 1.1 in good heat conducting connection with this and preferably this faces and the heat cost allocator 1 further comprises a second sensor, a room temperature sensor 1.3, on, the heat-insulated as possible relative to the radiator 1.1 is arranged in the heat cost allocator 1, facing the room to be heated 3 and to detect its temperature. Furthermore, the heat cost allocator 1 has an electronics 1.4, which in particular contains a clock or a timer, by means of which the temperatures detected by the sensors 1.2 and 1.3 or their difference are assigned to a time or time period; in the latter case, a comparison element (comparator) is included. In addition, a memory may be provided, in which the temperatures, times or time intervals detected by the sensors 1.2, 1.3 are assigned. • · · · * * • · · · * *

Furthermore, a transmission device 1.5 is provided in the heat cost allocator 1, by means of which the detected, described above physical values can either be issued at certain times, in particular on request or permanently; in the latter case, no separate storage is necessary in the heating cost allocator 1. The output can be made via contacts or contactless, in the latter case then wirelessly via suitable radio frequencies.
    The transfer takes place to a processing unit 3, in which the evaluation of the detected physical values takes place in order to carry out a consumption calculation for a recording unit, in particular a building, over a billing period (usually one year).
    The device according to the invention preferably and in particular in the illustrated embodiment, a second heat utilization detection unit 2, which is also attached to another radiator 2.2 and has the same parts as the heat utilization detection unit 1, by the corresponding reference numerals (instead of 1 ..... here 2 .....) are designated.
    As far as no comparator or comparator is contained in the heat utilization detection units 1, 2, such is necessarily provided in the evaluation unit 4.
    The method steps of the method according to the invention are shown in the flow chart of FIG. 2.
    First, a detection of the radiator temperatures ΤΗκί and the room temperatures T ^, i = 1 to N, in all in a detection unit, such as a building, existing heat detection devices or heat cost allocators 1, 2 ... n (step A). In principle, they can be assigned separately to a specific time or a time interval, stored and forwarded to later processing. n * * * (< > ·····. .. ·· 7 ·· ·· · *
    In the exemplary embodiment shown, a comparison of the respective radiator temperature THKi detected by the radiator temperature sensor with the room temperature Tri detected by the room temperature sensor arranged in the same distributor is made immediately for all detected temperatures of a time interval (step B). If the temperatures - within a tolerance range - are not the same, the usual further processing of the heat utilization detection takes place via step B1 and further steps on the basis of the temperature differences for the detection time intervals between the detected radiator temperature and the detected room temperature.
    If the two temperatures mentioned in the checked time interval, but here, for example, for the radiator 1.1, then in step C further detection to see whether for this radiator or heat cost allocator, the two temperatures THki and Tr, above a predetermined basic temperature Tg are (ie is equal to (or above) or greater than this), this basic temperature being one which corresponds to a customary usable room climate, can be set freely and set for example between 20 and 22 ° C.
    If this is not the case, according to C1 no measured value is recorded.
    If the temperatures mentioned are equal to or greater than the predetermined basic temperature Tg, then in one embodiment a check can be made as to whether the measurement date tD of the detection time interval is within a fixed heating period, for example between the first 01.10. one year until 30.04. of the following year or even regionally deviating. If this is not the case, no measured value acquisition (D1) takes place again. Alternatively, it can also be provided in principle that no measured value detection takes place outside of the heating period mentioned, this is thus already interrupted in the heating cost allocators 1, 2 in the period lying outside the heating period.
    In a preferred development, either in addition to the preceding method step E or else alternatively be provided that -
    Requirement that in a heat cost allocator, here heat cost allocator 1, the radiator temperature and the room temperature are the same, in all other Heizkostenverteiiern (J = 2, ... N of the detection unit) is checked in the building, if one of them, the radiator temperature is higher than that Room temperature, for example, the heat cost allocator 2, the temperature measured by the radiator temperature sensor 1.2 is above the temperature measured by the room temperature sensor 2.3. If this is not the case, i. if there is no time body of the detection unit, the radiator temperature exceeds the ambient room temperature, then there is no dynamically determined heating period and there is no measured value detection, in particular for the heating cost allocator 1 (but also for all other heat cost allocators) (step E1).
    If a heating radiator j is arranged with a temperature difference between radiator and room temperature in the same room as a radiator i without difference between radiator and room temperature (step F), it is assumed that the room is heated by the radiator j, this heater is sufficient and therefore the radiator i is turned off, so that this is not taken into account in the determination of a fictitious heating power on the determined in one of the heating period as described (F1).
    However, if at least one of the further heat cost allocators (not in the space of radiator 1.1 located on a radiator 1.2), for example in the heating costs distributor 2 of the embodiment of Fig. 1 in step E above the room temperature Tr2 radiator temperature Thk2 found (and not omitted by step F), the time interval for which, under the aforementioned conditions, the room and radiator temperature are equal to 1.1 (or i) of the radiator taken, for example, is recorded and stored, and a total time for all Intervals in which the aforementioned conditions are given add up to a total time ti for all intervals at which the given conditions are given (step G).
    In the evaluation unit 4, to which the data are transmitted either at a specific polling time or continuously, a fictitious heat utilization and consumption value, in addition to the heat utilization detected in the usual way due to the temperature differences between radiator temperature and room temperature and the associated times, Here Vti = Fi x ti - be assigned in the present example for the radiator 1.1 with a time multiplicatively attributable consumption factor Fi according to step H, which detects the times at which a radiator emits heat even in a room to the ambient temperature, but still Heat is used in this room, either through continuous heating pipes in old buildings, due to the heating of surrounding rooms, especially from neighboring apartments, heat absorbed from the staircase or staircase or the like.
    The fictitious consumption value is attributed to the determined in the usual and described manner consumption due to temperature differences between radiator and room temperature determined heat smoke according to step I additively, so that by means of the inventive method a total consumption of usually certain consumption a total consumption VG1 determined in the usual way by measurement the temperature differences given consumption VM1 and fictitious consumption VF1. The method according to the invention for detecting heat utilization during the heating period at temperatures above a basic room temperature without increased radiator temperature in a room above the room temperature - and thus due to other heat sources - therefore leads overall to a more equitable distribution of the heat costs.
