Definitions

  • the invention relates to a device and a method for determining the energy input into a room by a radiation source.
  • the temperature in the room to be heated or cooled is ideally determined and the thermostat of the system is regulated accordingly.
  • a disadvantage of the known systems is that the control is usually based solely on the determination of the room temperature and foreign energy that is registered in rooms, can not directly consider or capture.
  • the heating, ventilation or air conditioning is not optimally controlled because, for example, a room in which additional external energy is entered, less heating must be used as a room in which no external energy is entered. If the external energy is considered only indirectly, thus more heating power is provided than is needed, which can reduce the efficiency of the heater.
  • the external energy which is registered for example by sunlight through the windows of a room (eg, rooms, buildings or vehicles) in a room, to order a heating, ventilation or air conditioning or the like for a New installation or replacement can be optimally dimensioned or optimally regulated during operation.
  • the object is achieved by a device for determining the energy input according to claim 1 and a method for determining the energy input according to claim 13.
  • the inventive method for determining the energy input into a room has the following steps. Initially, at least one room outside (eg wise building, room or vehicle outside), which has at least one window, at least one radiation sensor attached. In order to determine the energy input, it is preferable to consider only the outside of the room, at which solar radiation can also occur to a decisive extent. If, for example, outer sides of buildings are constantly shadowed by neighboring buildings, these outer spaces, even if they have windows, do not necessarily have to be provided with a radiation sensor, since no appreciable energy input takes place.
  • At least one radiation sensor is arranged on the corresponding outer space sides, or a radiation sensor package consisting essentially of a cuboid on which radiation sensors are arranged on each surface except the bottom surface and, if necessary, surfaces for which no relevant irradiation is expected , arranged on an unshaded place, for example on the top of the room.
  • the incident radiation is determined over time.
  • the window area on the associated side of the room is determined.
  • the energy input then results from the radiation detected by the radiation sensors over time and the associated window area per room or building. If the solar radiation is determined in W / m 2 and the window area in m 2 , the energy input as the integral of the value determined for the solar irradiation over the time multiplied by the value of the window area, for example in the unit kWh / m 2 .
  • the determination of the energy input into a room allows the To determine the energy balance of the room and the energy difference that must be additionally applied by a heater or air conditioning in order to achieve or maintain a predetermined room temperature to determine.
  • the input of external energy is generally essentially determined by the solar radiation incident through the window.
  • the external energy input to be considered can be determined by determining the energy input which results from the irradiation, in particular the solar radiation, over time on the different sides of the room and the window area lying on these sides.
  • the method according to the invention can optimize the degree of utilization of a heating or an air conditioning system in the following way. For example, since a room in which the sun is shining through a window is already heated by the sunlight, less power or work of the heating is required to heat the room to the predetermined final temperature. By taking into account the external energy input only the differential energy is requested by the heater, so that lower losses occur, whereby the degree of utilization of the heating is improved. Furthermore, the knowledge of foreign energy inputs into a room over time (any cycle over seconds, hours, days, weeks) allows a correspondingly optimized technical and energetic room management, for example, for a building, a vehicle or a ship.
