    535 883 Known technology A group of products that are currently marketed intensively by, among others, the energy companies, are various forms of power and energy meters that show electricity consumption. Data from these meters are displayed in a variety of ways such as instantaneous value, comparative values, history, statistics and more. The costs of household electricity are often also shown in different time perspectives. The information is usually transmitted via a network to a computer, mobile phone or to a specially developed product that can be placed on. a suitable place in the house and which is connected to the house's electricity meter.
    Another group of products that are marketed are more creative and provide many other perspectives on the visualization of energy consumption in the present or in comparison with previous consumption. Some of these products also provide information on when a product should be turned off or when a particular behavior should be changed. Several of the products show great ingenuity and in themselves create great attention. However, there is a need for a system that can cover the entire energy system in a building and that can calculate the suitability of the connection or disconnection as well as the operation of an energy converter or energy accumulator in a building.
    A number of patented and patent pending systems for monitoring the energy use in a building are already known. For example, such a system is described in patent specification US201100149984. However, the construction according to the patent specification differs significantly from the system according to the present patent application.
    U.S. Pat. No. 7,696,3670 describes a variant of a system for monitoring individual consumers in a building or the like. However, the system according to the patent specification differs significantly from the system according to the present patent application.
    Patent specification US73 17404 describes a variant of a unit for indicating the energy consumption of the individual consumer. The method and system described in the patent air do not include a system in accordance with the present patent application.
    U.S. Pat. No. 4,754,1941 discloses a system and method for controlling the consumption of an energy network. The method and system described in the patent specification do not comprise a system in accordance with the present patent application 535 883 The objects of the present invention The main object of the present invention is to create a system for controlling the energy balance in a building, dwelling, premises or the like. Another aim of the present patent application is to create a system that is more energy efficient than previously known systems. It is a further object of the present patent application to create an indicating unit with which the suitability of connecting an additional consumer can be determined. It is further an object of the present patent application to create a system for taking a certain energy converter out of operation when it is inappropriate to use it any longer.
    Brief Description of Figures In the following detailed description of the present invention, reference and reference to figures will be made. These figures are briefly described in the following ur gur list. The embodiments exemplified in the foregoing are not limiting of the scope of protection of the present patent application. Note that the ñgurema are schematic and that details can thus be omitted in these.
    Figure 1 schematically shows an energy system in accordance with the present patent application.
    Figure 2 shows an exemplary function of an indicator in accordance with the present patent application.
    Detailed Description of the Present Invention Referring to the figures, there is shown a system 1 for controlling the energy balance of an energy system comprising a plurality of different energy converting or energy storage units 2 in a building, dwelling, premises or the like. System 1 is intended to determine the suitability of, from an energy balance point of view, incorporating at least one energy converting or energy accumulating unit 2 included in the energy system. In alternative embodiments, it is conceivable that the system 1 is also used to determine the suitability of keeping at least one of the energy converting or energy accumulating units 2 in operation. In further alternative embodiments, it is further conceivable that the system is intended to determine the suitability to switch off at least one energy converting or energy accumulating unit 2 at the current moment to the energy system.
    In the exemplary embodiment of the system, a number of different energy converting or energy accumulating units 2 have been connected to the system 1. The energy converting 535 883 units and the energy accumulating units 2 can consist of a number of different types of units. For example, the energy converting units and energy accumulating units 2 may consist of refrigerators, freezers, dishwashers, washing machines, dryers, car heaters, showers, baths, wood-burning stoves with several units and devices.
    The suitability of using the individual energy converting or energy accumulating units 2 in the system 1 is calculated on the basis of the other energy converting or energy accumulating units 2 energy status and the energy situation of the energy producers.
    The system strives to create a balance in the entire building, dwelling, premises or similar energy system.
    To control the energy balance in the building, dwelling, premises or the like, the system comprises at least a first indicator 4 (indicator unit) which is connected to at least a first energy converting or energy accumulating unit 2 included in the energy system and at least a second indicator (indicator unit) 4 which is connected to a second energy actuating or energy converting unit included in the energy system. Preferably, a number of indicators 4 are used, which are preferably connected to each energy-converting or energy-accumulated unit 2.
    The respective indicator 4 is connected via at least one communication unit to at least a second indicator 4 or at least one central unit in the system. The respective indicator preferably comprises at least one CPU and at least one associated memory unit. Preferably, information about the energy status of each energy accumulating or energy converting unit 2 is transferred from at least one indicator 4 to at least one second indicator 4. It is also conceivable that information is transferred from at least one first energy accumulating or energy converting unit 2 to at least one central unit in the system. to the respective indicator 4 in the system.
    The display units can be placed on a number of different devices. For example, the display units can be placed on the fridge, freezer, dishwasher and washing machine, dryer, car heater, shower, bath, wood stove with your components. Each indicator (indicator unit) 4 has been coded for different types of consumption such as hot water, cooling or electricity. Visually, the suitability of connecting the energy converting or energy accumulating unit is indicated directly on the indicator, which is preferably connected to the energy converting or energy accumulating unit. Via information on the indicator, it is possible for the user to quickly determine whether, for example, the energy converting or energy accumulating unit should be started at 535 883 right now or whether it is better to wait until a later time. The indicator includes a function by which a delayed start of the energy converting or energy accumulating unit can be performed.
    The present system and the indicating unit preferably intend to visualize the current / momentary energy situation - (supply and cost) - both centrally and decentralized on at least one and preferably on each individual energy converting or energy accumulating unit. The system provides guidance on whether an individual energy converting or energy accumulating unit 2 should be taken into account from an energy cost point of view or not. In alternative embodiments, the system may provide guidance as to whether at least one energy converting or energy accumulating unit should be kept in operation or whether it should be switched off.
    Referring to Figure 2, a schematic exemplary embodiment of the present indicator is shown. In its simplest design, the indicator comprises at least one sensor or the like which detects whether the energy converting or energy accumulating unit is in operation or not. The indicator includes at least one display window. The indicator shows at least one signal in the display window that recommends an energy-efficient choice for the user regarding the device to which the indicator belongs.
    If the energy-converting or energy-accumulating unit is not in operation, the indicator may show the suitability for commissioning the energy-converting or energy-accumulating unit. In the simplest embodiment, the indicator shows whether it is appropriate or not to put the connected energy-converting or energy-accumulating unit 2 into operation. The learning obligation to put the energy-converting or energy-accumulating unit into operation can be reported in a number of different ways. It is conceivable that the suitability is reported via light signal, sound signals or by a combination of these signals. The signals can be given at command or spontaneously. The signals can be emitted continuously or intensely. Alternatively, the signals may be emitted in another manner suitable for the purpose.
    In a preferred embodiment of the indicators of the present system, the indicators emit visual signals in at least three different colors to the user. By indicating with signal 5 in a first color such as “green”, the system shows that from an energy and cost point of view it is advantageous to take the device in drive fi. By indicating with a signal 6 in a second color such as 535 883 “yellow” shows that it is neither good nor bad from an energy and cost point of view to take the device in drive fi. By indicating with a signal 7 third color such as "red" it is shown that there is either a shortcoming in the system or that it is expensive to use the device in question. The same principle is used on energy sources such as a wood stove and or a pellet stove, ie the system indicates whether it is advantageous from an energy and cost point of view to fire or not.
    The system is not mandatory but only provides a basis for the user's decision to use the current energy converting or energy accumulating device. The device can be used even if the indicator shows "red" but at a higher cost. If, on the other hand, the indicator shows "green", it is known that it is largely "free" to use the energy-converting or energy-accumulating unit.
    Examples of using the present system In the summer when, for example, the air conditioning is in operation, heat is produced simultaneously by the heat pump and this heat can in this situation be regarded as “free” and must, if not used, be cooled off to the surroundings. In this mode, the indicator on, for example, washing machine and dishwasher, shower and bath shows "green" and the wood stove "red". Correspondingly, the corresponding indicators show the reverse "red" and "green" respectively on a cold winter day when an immersion heater must be added as an additive to the heat pump to keep the house warm. In the shower, the indicator shows green if, for example, cold is produced or if the heat from the car has recently been charged. In the nomial case when the heat pump produces the hot water, the indicator shows "yellow" while it shows "red" in cases where the electrical additive must go in or the amount of hot water is low. During a long shower, the indicator can thus ski from “green” to “yellow” and to “red”.
    The energy systems that are developed for tomorrow's energy-negative and environmentally friendly homes and premises will be complex and may contain one or fl your different types of renewable energy sources - solar heat, solar, heat pumps and bioenergy in combination with eg direct and district heating. The energy systems will also have technical solutions for heat recovery in wastewater and in the long run also consumption water. All of this requires an advanced control and regulation system that controls the energy system in an optimal way and utilizes the saving potential of the individual components. It will also mean that the supply of cheap energy within the property will vary greatly. You could see it as a spot price for energy - electricity, heat energy, cooling - within the property that varies with the current use / need, weather, time on day and season. With the development of the “smart grid” 535 883 systems, the complexity of controlling the systems will increase further as the supply and price of electricity to the property will vary.
    In the detailed description of the present invention, structural details and subsystems may be omitted which will be apparent to one skilled in the art to which the method and apparatus relate. Such obvious construction details and the sub-sister are included to the extent required for a proper function to be obtained for the present system with components included. Although certain preferred embodiments have been shown in more detail, variations and modifications of the method and apparatus may be apparent to those skilled in the art to which this invention pertains. All such modifications and variations are considered to fall within the scope of the appended claims.
    Advantages of the Invention With the present invention, a number of advantages are achieved. The most obvious advantage is that a system which can effectively monitor the energy balance in an energy system can be obtained. Another advantage of the present patent application is that display units are created with which individual energy converters and energy accumulators can be monitored.
    Another advantage of the present invention is that the system effectively visualizes the house's current energy situation with respect to both energy supply and energy cost and that the user in each decision situation receives information about the situation that guides him or her in the decision to put an appliance into operation or not. . The strength of the method we present is that it is not based on past, historical or current electricity consumption, as most of the systems available on the market do, but on the total energy situation in the property as a whole. We therefore believe that the savings point of view of the proposed system will be relatively large and sustainable due to the fact that the basis for the decision is perceived as relevant. Through the design of the proposal, we can influence the behavior of users and at the same time provide the opportunity for feedback to the user.
