Description

BRIEF DESCRIPTION OF THE DRAWING

[0025] The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein: the sole FIGURE schematically shows a piece of real estate, including a heating device, by way of example.

DETAILED DESCRIPTION

[0026] The FIGURE shows a schematic view of a piece of real estate 1, including a heating device 2. Heating device 2 is connected via a large number of heating circuit lines 15 to a large number of heat transfer devices 3.1 through 3.4, which are each situated in a room 5.1 through 5.4 of piece of real estate 1. A heat transfer medium may be heated by heating device 2 and supplied to heat transfer devices 3.1 through 3.4 via heating circuit lines 15, so that heat transfer device 3.1 through 3.4 may heat a room air in rooms 5.1 through 5.4. The at least partially cooled heat transfer medium is subsequently fed back to heating device 2 via additional heating circuit lines 15. A heating circuit 16 is thus formed in piece of real estate 1 by heating circuit lines 15. The heat transfer medium may be supplied to heating circuit 16 via a fluid source 11, for example a public water supply network, if losses of the heat transfer medium occur in heating circuit 16, for example due to leaks. A measuring device 10, comprising a first temperature sensor 12, a flow sensor 13, a pressure sensor 14 and a vibration sensor 7, is disposed directly downstream from heating device 2. A temperature of the heat transfer medium in heating circuit line 15 may be determined with the aid of first temperature sensor 12, a volume flow of the heat transfer medium flowing through heating circuit line 15 may be determined with the aid of flow sensor 13, and a pressure of the heat transfer medium flowing through heating circuit line 15 may be determined with the aid of pressure sensor 14. Vibrations at heating circuit lines 15 may also be measured with the aid of vibration sensor 7. Measuring device 10 is data-conductively connected to a controller 8 for transmitting the measured values measured by the sensors. Controller 8 is also data-conductively connected to second temperature sensors 4.1 through 4.4 situated in individual rooms 5.1 through 5.4 for determining an air temperature in individual rooms 5.1 through 5.4 as well as to humidity sensors 6 situated in room 5.1 for determining a humidity in room 5.1. It should be noted that a humidity sensor 6 may be disposed in each room 5.1 through 5.4. Controller 8 is furthermore connected to an outdoor temperature sensor 17, with the aid of which an outdoor temperature may be determined. Outdoor temperature sensor 17 is also data-conductively connected to controller 8. An energy efficiency of piece of real estate 1 may thus be calculated with the aid of controller 8. Controller 8 may be situated in piece of real estate 1 and/or be provided in a cloud device 9.

[0027] The energy demand of the piece of real estate may be monitored continuously by the present invention.

[0028] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims
