  • the present invention relates to a method for controlling the heat flows in at least one building, in which methods for controlling the temperature within the building are controlled from a plurality of input parameters.
  • Optimizing the heat flow in a building is something that residents have always dealt with intensively.
  • the modern means of air conditioning (cooling, heating, setting the air humidity) have made it much easier to influence the flow of heat, but saving energy is a big issue, especially considering economic and ecological aspects.
  • Heating houses private, commercial and public
  • any optimization in this area is potentially extremely interesting.
  • the invention is therefore based on the object of providing a method and a device for controlling the heat flows in at least one building, in which means for influencing the temperature within the building are controlled from a plurality of input parameters.
  • the regulation should be as forward-looking and efficient as possible.
  • the means for controlling the temperature of a specific, considered space or at least a region of a specific space are controlled by the following as input parameters: a) at least one target value, in particular the desired temperature of the specific space; b) at least one general parameter which is characteristic of at least one size inside and / or outside the building and which at least indirectly influences the temperature within the specific room; and c) at least one special parameter which is characteristic of the specific heat flow conditions of the specific space under consideration or of the area of the specific space; are used and the control of the means is calculated from these input parameters in a control unit.
  • the essence of the invention is therefore to design the control specifically for each room in an adapted manner. For this purpose, a target value is defined for each room, which can be different for different rooms.
  • This target can either be fixed by the user, possibly depending on the time of day and day of the week etc. (schedule). Or it is also possible to derive this target value from a history, so to speak, that is, the control unit "observes", if necessary additionally via motion sensors, the effective use of the corresponding space and automatically adjusts the heat flows to the actually expected use. If, for example, a room is never needed on weekends, and usually not on Monday morning, the control unit determines this and after a certain number of repetitions of such regular behavior, the control unit reacts automatically by adjusting the target value accordingly defining, sets a minimum value when there is typically no person in the room and to a different target value when the presence of a person is typically to be expected.
  • the presence of people can be determined in a room-specific manner, as already mentioned, using sensors, but it is also possible to do this e.g. B. derived from indirect sizes such as the presence of the person who usually works in the room under consideration, as can be seen from a time monitoring system, or by querying the local computer network whether the person in question is logged in or not.
  • At least one general parameter is used as an input variable, which to a certain extent stands for external, variable factors influencing the heat flows of the room under consideration.
  • it is e.g. B. the temperature outside the building, this temperature is particularly preferably measured where possible, which are particularly relevant for the room under consideration.
  • special parameters are provided in particular as input variables for the control, these special parameters being characteristic for the heat input or the heat outflow from the room under consideration.
  • these are sizes such as B. the window surfaces and their Isolation state of the room under consideration or similar such sizes.
  • the means for temperature control are typically at least one heater.
  • these means comprise at least one air conditioning system and / or at least one ventilation system and / or at least one device for influencing the solar radiation (for example sun blinds) in the room.
  • the control unit has access to a database in which historical values of the parameters (b, c) and the target values (a) of the specific space under consideration and / or the specific building under consideration are contained.
  • the means for temperature control are controlled from the input parameters taking these historical values into account, with the control of the means for temperature control from the input parameters being particularly preferably optimized in an adaptation process, taking these historical values into account. It is, to a certain extent, an intelligent learning process that runs in the control unit and that optimally takes into account the microclimate typical of the specific building and even the specific room.
  • this embodiment has the advantage that such a system does not require any special installation steps to be adapted for the specific object, since after a certain learning period in which the system is optimized autonomously, the control is specifically set optimally.
  • a combination is of course possible by already storing a rough data set suspected for the specific object as a starting value for the history so that the settling behavior of the control system, which usually occurs in such learning processes, is not too pronounced.
  • the at least one general parameter is one or a selection from the following parameters, in particular measured by sensors: temperature on the outside of the building under consideration (temperature sensors on different facades at different heights on the outside of the building); Moisture on the outside of the viewed Building (moisture sensors also on the different facades); Wind and in particular wind direction on the outside of the building under consideration (e.g. wind turbine on the roof); the solar radiation on the outside of the building under consideration (brightness sensors also on the different facades on the outside or, if necessary, also in the room in places where the window can be expected to emit somien radiation).
  • These general parameters are particularly preferably measured at several points with different clinic influences for the space under consideration, such as on different facades and / or on the roof of the building, possibly at different heights.
  • information about the weather forecast, in particular of the region may be used as a general parameter (possibly a combination of global weather forecasts, e.g. for the country, and local weather forecasts, e.g. for the region).
  • These data can e.g. B. consist of a corresponding provider providing precipitation waliischlicliceiten, Sonnenst ⁇ ndenwalirscheinlicl, etc. in a defined form, depending on the time of day if possible.
  • Such a system can be implemented particularly easily using today's technical means if the general parameters are at least partially via a wired or wireless network, particularly preferably via a LAN, wireless LAN, GPRS or the like, using standard protocols such as SMTP, ftp, http be transmitted to the control unit periodically or continuously. It is particularly easy to do e.g. B. integrate the weather forecast into the system by periodically accessing a corresponding provider via the WWW from the control unit in order to collect the corresponding information, or by actively sending the information from a provider to specific control units. This can be done using standard protocols such as SMTP or HTTP, whereby the information is passed in a defined format (eg XML / SOAP) so that it can be automatically processed by the control units.
  • SMTP Simple Object Access Protocol
  • HTTP HyperText Transfer Protocol
  • Another preferred embodiment of the present invention not only uses the parameters measured on the building under consideration, but also uses parameters from other buildings which are integrated in a similar system. This allows a further adjustment of the control to the MikiOry valid for the object in question.
  • general parameters as described above are also used as input parameters, which are measured on at least one other building, these other buildings particularly preferably adjacent or at a distance relevant to the climate, in particular the microclimate, of the building under consideration is arranged.
  • each building of a corresponding network makes its data available in a general database managed by a provider to the control units of other buildings. Accordingly, the control units of other buildings can then access the entirety of this data and optimize their regulation, which can be of particular interest in connection with the above-mentioned learning process using a history if the database does not only include the current values but also the buildings also historical data.
  • the value of the temperature in the specific room under consideration and / or the value of the temperature in neighboring specific rooms should also be used as input parameters.

  • These specific parameters can either be determined once and entered into the tax input, and / or it is possible to have the entire influence of at least certain of these specific parameters automatically by the tax input in an, if appropriate continuous, adaptation process, taking into account the influence of the general parameters and to determine the activation of the temperature control means to the value actually brought about in the specific room.
