    The invention relates to a high-pressure mist system with a compressor and a misting valve for producing floatable fog of a liquid medium, such as e.g. Water, wherein the nebulizer valve is connected to an electronic control.
    In high-pressure mist systems produces fine water mist by high-pressure water (70 to 100 bar) by fine high-pressure nozzles (single-fluid nozzles) is pressed. The resulting small water particles (about 5 my = 0.005 mm) can cool the ambient air through complete evaporation (= evaporation cold) and moisturize. The currently commercially available high pressure mist systems can turn on and off only a single high pressure pump, switch pulse / pause and are suitable for only a single zone area. Each additional zone again requires its own high-pressure pump and another controller, hence another separate high-pressure mist system. These controllers are difficult to expand, expensive to purchase and have no control over the overall system status or the operation of a high pressure mist system. Due to the unique piece production, these switch controls are very expensive to buy, to maintain and to service. A further development of these controls is not possible. The total resources of two coexistent high pressure fog systems can not be exploited due to the simplicity of the controls.
    The invention aims to provide a high-pressure mist system, as stated at the outset, which makes it possible to produce floatable mist of a liquid medium, such as water mist, at different locations for different purposes depending on predetermined climatic conditions. This should be achieved in a resource-saving, efficient and easily controllable way.
    The high-pressure mist system according to the invention achieves this by having means for connecting at least one further nebulizing valve, that the controller has means for connecting at least one sensor, and that stored in the controller, a program for converting data from at least one sensor into separate control commands at least two nebulization is.
    A preferred embodiment of the high-pressure mist system is characterized in that the sensor or sensors are temperature sensors, humidity sensors or / or wind sensors.
    In one embodiment of the invention, at least one discharge valve and a pressure relief valve are arranged at a high pressure side output of the compressor.
    For further embodiment of the invention, a program for triggering an alarm in dependence of predetermined data, which are output from the at least one sensor stored in the controller.
    Preferred in one embodiment of the invention is that a pressure relief valve is disposed adjacent to each nebulization valve.
    It is further preferred in an embodiment of the high-pressure mist system according to the invention that in the high-pressure mist system via a valve, a reservoir with an odor binder for mixing the odor binder is connected to the liquid medium to be atomized.
    The invention will be explained in more detail with reference to an embodiment shown in the drawing. The figure shows a schematic circuit diagram of the high-pressure mist system.
    In the high-pressure mist system 1 shown in the figure, water is taken from a reservoir 2 and pumped by a compressor 3 via a line 4 to one or more nebulization valves 5, opens a nebulization valve 5, the water passes, the increased pressure of about 70 to 100 bar stands, to a nebulization (Einstoffdüse) 5 ', from which the water emerges and is atomized. The water reservoir 2 may be, for example, the ordinary drinking water a: line. As a compressor 3, commercial high-pressure pumps can be used. An electronic controller {not shown) now controls the compressor 3 in terms of operating times and operating mode, such as the amount of pressure to be generated. For this purpose, operating values of the high-pressure mist system 1 are entered into a program which is stored in the electronic control. Such operating values come from different sensors. This is a low-pressure sensor 6 on the input side of the compressor 3, a high-pressure sensor 7 on the output side of the compressor 3 and other sensors (not shown) in the vicinity of the or the nebulization 5 or nebulization 5 '.
    In conventional high pressure mist systems, a compressor is controlled to be turned on or off according to a predetermined time pattern. By combining the electronic control with sensors that detect climatic values in the area of a misting valve 5, and with an electronic controllability of the compressor 3 and the nebulization or the 5 or the electronic control, the surprising effect that the high-pressure mist system only in Operation and floating water mist is only generated at a specific location, if this is necessary for predetermined reasons. Furthermore, the high-pressure mist system has means which make it possible to connect at least one further nebulizing valve 5 with nebulizing opening 5 'to the line 4 of the compressor 3 in addition to a first nebulizing valve 5. Such connections can be provided in mechanically known ways. A misting valve 5 may be a high pressure solenoid valve. With other pairs of nebulization valves 5 and sensors controlled by the one electronic controller, climatically changing, buoyant water mist may be generated in different zones by a single high pressure mist system 1. For example, in the drawing, two zones are schematically shown as "Zone 1". and "Zone 2" designated. Although parts of the same high-pressure mist system 1 are installed in both zones, the climate in each individual zone can be changed independently of the other zone. The generated floatable water mist acts in several directions. On the one hand, it can quickly increase the humidity, and on the other hand, by evaporation, lower the temperature value in the vicinity of a nebulization valve 5. In addition, water mist can quickly bind dust and odors contained in the air and remove it from the air. By adding an odor-binding agent to the water that forms the mist, finally, a further effect of the mist can be made possible, namely the distribution of an odor-binding agent in the zones. In order to take advantage of these various climate impact opportunities in the zones, the sensors positioned in the area of nebulization valves 5 or nebulization port 5 'are typically temperature sensors, humidity sensors, wind sensors, and other sensors. Typically, a sensor or a bundle of sensors converts the measured climatic conditions into an electrical signal that can be evaluated by the electronic control system. The electrical control assigns a zone number to each electrical signal and calculates, for example, whether and how long the corresponding nebulizer valve (s) should be opened in that zone. The zones are previously defined in the electronic control. The behavior of the control depends on the selected program, there are the following programs:
    Barn:
    The humidity in the individual zones is kept constant. If it falls below a minimum temperature value, no further nebulization takes place. If a maximum value of the humidity is exceeded, the misting is also prevented.
    Wine storage / Glass House:
    It is regulated to a constant humidity. The value of the temperature is not taken into account.
    Indoor:
    The temperature is kept constant. If a maximum value for the humidity is reached, no further misting occurs, even if the temperature is too high.
    Outdoor:
    It is regulated to a constant temperature. The value of the humidity is not taken into account.
    Odor / dust:
    Within a set interval is controlled permanently. For the program "Smell / Dust " can be set extra a time interval. These are in addition to the individual days of the week and "daily". the options "weekdays" (Monday to Friday) and "Weekend" (Saturday and Sunday) available. These settings apply only when the program "Smell / Dust " was selected. Otherwise they will not affect the other time programs.
    No program:
    If this program is set, the system is not monitored. It then behaves like in the "Off" mode. All programs are subject to the same basic conditions of minimum temperature, maximum humidity, temperature hysteresis, humidity hysteresis and switch-on delay between two zones. Depending on the program selected, these parameters are taken into account or ignored. An adjustable delay time between the switch-on time - 8 "* 8" * * "" ••• "•• ft *" * "#" t "•" "" points of the zones prevents an excessive pressure drop in the system.
    The advantages of this system are that resources can be used more efficiently and the high-pressure misting system 1 can be flexibly and easily expanded or reduced again. In order to ensure safe automatic operation without permanent human control, it is advantageous at the high-pressure side outlet of the compressor 3, i. on the line 4, a main drain valve 8 to be arranged to quickly release the pressure after switching off the high-pressure pump in the line 4 when needed. At overpressure in the line 4, a pressure relief valve 9 and a safety circulation valve 10 is switched.
    In some applications, it may be advantageous if the high-pressure mist system 1 does not manifest itself otherwise than through the discrete generation of suspended mist of water. It may be perceived as disturbing that a nebulization opening 5 'drips once or for a short time after closing, because when closing the valves, the pressure in the line drops and it can lead to dripping. To prevent this, a drain or pressure relief valve 11 may be disposed in the vicinity of each nebulizer valve 5 in the water loop. The electronic controller will then open the pressure relief valve 11 shortly before, or shortly after, and shortly before, and shortly after, the closing time of the respective nebulization valve 5 to rapidly reduce the pressure at the nebulization port 5 '.
    The water to be atomized can be added via a mixer 14, an odor binder from a reservoir 13. The electronic control may do so either according to a predetermined time pattern or taking into account a signal from an odor sensor mounted in one of the zones.
    The electronic control can be designed as a computer. That is, it has a storage medium, a processor, a power source, interfaces for connecting the sensors, as well as interfaces for connection to input and output devices, such. a monitor, for the user. As a result, a program can be installed on the electronic control system, which offers further functions for the easy and safe use of the high-pressure mist system 1. So the compressor can be monitored by a diagnostic system. Two methods are checked and, if necessary, alarms are activated:
    The compressor does not generate pressure.
    Here it is checked whether after an adjustable time the compressor 3 was able to increase the pressure by an adjustable value. The alarm is activated if the following conditions are not met after the set time has expired: Compressor activation pressure + set pressure difference < current pressure
    Pressure can not be removed again.
    In this alarm, it is checked whether after a settable time after opening the main drain valve 8, the pressure has dropped by an adjustable value. This alarm is activated if the following condition is not met:
    Pressure when opening the main drain valve 8 - set pressure difference < current pressure
    If an alarm has occurred in the system, the system will be stopped until all alarms on the electronic controller are cleared. In addition, the high-pressure mist system 1 according to the invention can offer a hygiene function. In doing so, the pipelines, such as e.g. the conduit 4, and the nozzles, e.g. the valve openings 5 'of the misting valves 5, cleaned. The hygiene function knows two stages. At stage 1, both the main drain valve 8 and the misting valve 5 are opened in the zone. As a result, the area behind the main drain valve 8 is flushed by the compressor. In stage 2, the main drain valve 8 is closed and the zone begins to fog. This allows a flushing of the area between nebulization valve 5 and nebulization openings 5 '. For each of the two levels, a corresponding duration can be set in the system.
    The high-pressure mist system 1 according to the invention can also provide a sensor calibration. For this purpose, a value for the deviation of the respective sensor of a sensor can be set. There are two values, one calibration value _ ^ * _ * · ** * * · «« ··· »» ·· »·····« · »· * ··» # »· · · · · · · * · «· ·« For humidity and temperature. Although this linear offset does not quite accurately reflect the actual aging of the sensors, it is a viable compromise that will be made so that a new value can be calibrated without much expense to the sensors of the sensors without the need for expensive multi-point calibration.
    Another advantage of the Hochdrucknebelanla-ge invention 1 is that all service data can be stored and processed by the electronic control. These data include predetermined service intervals for, for example, the compressor maintenance, a possible filter control, sterilization, descaling, calibration and cleaning. The electronic controller may then indicate, based on an internal clock running the particular service operations to be done or detected.
    Another advantageous function is the error log. The error log displays all system messages (alarm, warning and information). In addition, the alarm output is switched in the event of an error. If an alarm or a warning occurs, a corresponding warning is entered in the error log. If the underlying condition no longer applies, a reset message is added to the error log for the respective message.
    Another advantage is that the high-pressure mist system 1 according to the invention can perform a diagnostic procedure without manual intervention by a user. If an error occurs in the system, this is detected by the diagnostic system. For example, the electronic controller can detect what is going on when the system is low pressure. This may be caused for example by pressure in the supply line to the compressor 3, which is too high or too low, or by a temperature that is too high or too low in the supply line to the compressor 3. With overpressure in the system, it may be because the compressor 3 generates excess pressure or that pressure in the system can not be reduced again.
    The system can further distinguish between alarm situations and warnings of excessive or too low pressures or temperatures in supply lines.
    The high pressure mist system may also be connected via the electronic controller to a communication network, such as the Internet. For example, there is a UMTS direct connection with a USB stick, which enables remote system maintenance. The visualization of the high-pressure mist system I in operating mode is possible through the system at any time and from anywhere with Internet access. Software updates can also be remotely played on the electronic control of the high-pressure mist system 1. ΦΦ Λ * * »» ~ 13 ~ · · * «« «· · · · · * * * * * * * *
    It is understood that the described embodiments are variously modified within the scope of the inventive concept, e.g. regarding the specific type of interfaces, sensors and mechanical design of water pipes, connections and valves.
