Method and device for controlling the thermal balance in buildings

Abstract

A method for controlling thermal flows in at least one building, according to which a mechanism for influencing the temperature within the building is controlled based on a plurality of input parameters. Controlling can be done in the most economical manner by triggering the mechanism that regulates the temperature of a specific monitored space or the at least one area of a specific space by using a) at least one target value, especially the desired temperature of the specific space, b) at least one general parameter characteristic of at least one variable inside and / or outside the building, which at least indirectly influences the temperature within the specific space, and c) at least one special parameter characteristic of the specific thermal flow conditions of the specific monitored space or the area of the specific space, as input parameters, and calculating the controlling of the mechanism from the input parameters in a control unit.

Description

TECHNICAL FIELD [0001] The present invention relates to a method for controlling the thermal flows in at least one building, according to which method means for controlling the temperature inside the building are controlled on the basis of a plurality of input parameters. PRIOR ART [0002] Optimizing the thermal flows in a building is something with which residents have always been intensely concerned. The modern means for air conditioning [0003] (cooling, heating, setting the humidity of the air) have significantly simplified the control of the thermal flows but great importance is attached to saving energy, in particular in view of the economic and ecological aspects. In particular heating houses (private, commercial and public) entails a large consumption of energy at central European latitudes, and any optimization in this area is potentially highly attractive. [0004] As a result of the large mass / volume of the heated objects they react extremely slowly, and in particular in the ...

Benefits of technology

[0012] According to a first particularly preferred embodiment of the present invention, 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. Correspondingly, the control of the means for controlling the temperature is carried out on the basis of the input parameters taking into account these historic values, wherein the control of the means for controlling the temperature on the basis of the input parameters in an adaptation process while taking into account these historic values is particularly preferred. The process here is, as it were, an intelligent learning process which takes place in the control unit and which takes into account, in an optimum way, the microclimate which is typical of the specific building and of the specific room. Inter alia, this embodiment has the advantage that such a system does not need particular installation steps which are to be adapted to the specific object since, after a specific learning time period in which the system optimizes itself automatically, the control is set in a specific optimum way. A combination is of course possible if an approximate data record, which is assumed for the specific object, is already stored during installation as a starting value for the history, in order to avoid the transient response behavior of the control which usually occurs during such learning processes being too pronounced.

[0015] A system such as this can be particularly easily implemented with the contemporary technical means if the general parameters are periodically or continuously transferred to the control unit via a cabled or cableless network, in particular preferably by means of a LAN, wireless LAN, GPRS or the like using standard protocols such as SMTP, ftp, http. It is particularly easy to integrate, for example, the weather forecast into the system by periodically accessing the corresponding provider by the control unit via the WWW in order to achieve the corresponding information, or by the information being actively transmitted to the specific control units by a provider. This may be done by using standard protocols such as, for example, SMTP or HTTP, with the information being transferred in a defined form (e.g. XML / SOAP) so that it can be further processed automatically by the control units.

Problems solved by technology

With such methods it is usually not possible to perform short-term and predictive control, for example when there is a sudden increase in the input of heat from the outside (period of sunny weather) or a sudden decrease in the application of heat the control reacts slowly and the temperature inside the building differs greatly from the target value.
