Description

The invention relates to an adjusting device with an optical data interface for adjusting a flow control valve in a temperature control system for buildings, an optical data transmission system with the adjusting device and a method for optical data transmission with the adjusting device.

The subject of this patent application is based on a patent application not yet disclosed on the filing date DE 10 2017 123 560.4 same applicant. The present invention is based on unpublished, internal knowledge and improvements from a product development for the technology from the aforementioned patent application of the applicant. Accordingly, portions of the present disclosure, the drawings, and independent claims include unpublished portions of the earlier subject matter, the technology of which is incorporated herein by reference.

A technical background of the invention lies in the maintenance or fault diagnosis of heating and air-conditioning systems for rooms, such as in particular floor heating, surface heating or cooling ceilings, which are installed in a building.

In the prior art, numerous arrangements and control methods for comfort and efficiency-oriented distribution and regulation of thermal energy by a hydraulic network in the building are known from heating construction, similar installations in buildings also being known for the distribution and regulation of air conditioning energy or heat extraction from rooms .

Heating systems are also known which have a central control device which controls various valves of heat exchangers and provide a wireless communication interface for comfort control by means of a remote control, an operating panel or a smartphone. Such communication interfaces to the central control device of a heating installation are based on widespread high-frequency transmission techniques such as blue tooth or wireless lan. In the case of a decentrally controlled heating system, the provision of separate transmitter / receiver modules for a wireless LAN connection to multiple components would be relatively cost-intensive, and in particular in the case of low frequency of use for maintenance and diagnostic purposes, would be inappropriate in terms of production.

The aforementioned patent application not yet disclosed on the filing date DE 10 2017 123 560.4 describes a setting device and a method for the self-regulating setting of a flow of a consumer loop with a heat exchanger, which are based on a calculation of an application-optimized spread between the flow temperature and the return temperature, that is to say a variable temperature difference in each consumer loop. The setting device forms the relevant component of a temperature control system in which the corresponding method is implemented and which has an assigned room thermostat. The temperature control system does not have a central control device, but rather a decentralized control structure in which the setting of a flow in each consumer loop is implemented by an independently regulating setting device.

In an alternative embodiment of the DE 10 2017 123 560.4 will suggest that an activation signal can be communicated via a wireless interface from a thermostat to an adjuster associated with the same room. Furthermore, it is alternatively proposed to also establish a connection between a smartphone, tablet, PC or the like and a setting device or a thermostat via such a wireless interface, as a result of which the user can be given a further input option to the system. In a continuation of the alternative mentioned, problems arise, however, as will be explained below.

If such an alternatively conceived adjustment device with a relatively inexpensive transmitter / receiver module, e.g. of Blue Tooth technology, and a connection to an external device is to be established, a parallel problem between the possible wireless connections can arise due to the parallel arrangement of a plurality of identical setting devices. On the one hand, it is not reliably recognizable and controllable on the part of the user whether a connection to a specific transmitter / receiver module is made from the plurality of setting devices. On the other hand, mutual radio interference from simultaneously activated, identical transmitter / receiver modules from adjusters arranged next to one another would be expected. In any case, further distinguishing features and control options by software and hardware would be required to remedy the situation. Such distinguishing features could not, however, be easily represented in an identical and therefore less expensive production of the adjusting devices.

Based on the state of the art and the unpublished subject of registration, It is an object of the present invention to provide an adjustment device for a corresponding, decentrally controlled temperature control system, which enables easy assignment of wireless data transmission to a specific adjustment device even in a distributor installation with a plurality of identical adjustment devices.

This object is achieved by the characterizing feature of an adjusting device according to claim 1 or 2. A system according to claim 7 and a method according to claim 11, which also solve the object, relate to the characteristic.

The setting device for the self-regulating setting of a flow control valve is characterized in particular by the fact that, according to the invention, it comprises an optical data interface which is set up to set up a wireless optical data transmission path between the setting device and an externally manageable, optical transmitter-receiver device.

A corresponding optical data transmission system, which has the setting device and an externally manageable, optical transmitter-receiver device, provides for this that an optical data transmission path is set up in a free space between the optical transmitter-receiver device and the optical data interface of the setting device.

A corresponding method for optical data transmission between a further developed embodiment of the setting device and an externally manageable optical transmitter-receiver device provides two steps for this in the sense of a bidirectional connection: transmission of light pulses in the optical data transmission path by a light source of the transmitter-receiver device and receiving the light pulses in the optical data transmission link by a light-sensitive sensor of the optical data interface of the setting device; or sending light pulses in the optical data transmission path by a light source of the optical data interface of the setting device and receiving the light pulses in the optical data transmission path by a light-sensitive sensor of the transceiver device.

In its most general form, the present invention therefore provides for the first time to provide a separate external data interface for each or each setting device of a flow control valve in a temperature control system, in which optical signals are transmitted in free space. For this purpose, it is provided that the external transmitter or receiver is a manageable or portable device.

A portable terminal can be guided in a targeted spatial assignment on an installation with a plurality of adjusters arranged next to one another, such as in particular on a distributor installation, in order to establish an individual optical coupling with the optical data interface of a specific adjuster. In this way, there is an intuitive handling of the optical data transmission according to the invention, which ensures a simple, clear and quick selection from a plurality of possible wireless connections with the setting devices on a distributor installation in the sense of the task.

The optical data transmission according to the invention on a setting device can be used, for example, in professional use by a specialist with an original diagnostic device for maintenance purposes or in use by an interested user with a suitable terminal device to obtain knowledge about an operating course of the temperature control system.

Advantageous developments of the present invention are the subject of the dependent claims.

According to one aspect of the invention, the optical data interface can comprise an adjacent arrangement of a light-sensitive sensor and a light source; wherein the light-sensitive sensor as a receiver or the light source as a transmitter in the optical data transmission path is selectively activated for receiving or sending data by the setting device. In this way, technical features are basically provided for a bidirectional optical data interface, so that not only an input, but also a reading out of data on the storage means of the computing unit is made possible in the setting device.

According to one aspect of the invention, the light-sensitive sensor can be designed as a photodiode. This is based on a technically simple implementation, which is available inexpensively as a standardized electronic component.

According to one aspect of the invention, the light source can be embodied as a light-emitting diode. This is based on a technically simple implementation, which is available inexpensively as a standardized electronic component.

According to one aspect of the invention, the optical data interface can be arranged within a translucent, closed housing section of the setting device. This protects the optical data interface from Influences of an installation environment included in the setting device. Furthermore, no further manipulations for opening a cover or the like are required.

According to one aspect of the invention, the externally manageable, optical transmitter-receiver device can be designed as a smartphone, which is equipped with a photo camera as a light-sensitive sensor and a photo flash device as a light source; wherein the photo camera as a receiver or the photo flash device as a transmitter in the optical data transmission path is selectively activated for receiving or sending data on the part of the smartphone. Thus, a user-friendly variant with regard to the external device is provided, since there is no need to purchase dedicated hardware.

According to one aspect of the invention, data can be transmitted within the optical data transmission path by means of light pulses. In comparison to an optical variant, which is based on other conceivable parameters, such as a modulation of brightness values or color values, the switch-on and switch-off states of a light source represent a technically simpler implementation.

According to one aspect of the invention, a binary transmission signal can be formed by means of time periods of light pulses and time periods of pauses between the light pulses in relation to a clock frequency. By using a time scale between binary states, a technically simple implementation is again achieved, which enables the use of an established coding in the form of optical Morse codes.

According to one aspect of the invention, processing logic of the calculation means of the smartphone, an update of data or an analysis of data via an internet connectivity of the smartphone to a server can be provided. This completes a user-friendly interface from a manufacturer or service provider to the installed temperature control system. In this way, user-friendly solutions for various technical tasks, such as maintenance, data collection, setting optimization or product improvement, can be provided.

The invention and a suitable technique for implementing the invention can be better understood from the description of the figures with reference to the accompanying drawing, the same reference numerals being used for the same objects, in which:

• 1 shows an optical transmission system according to the invention on a setting device with a smartphone, between which an optical data transmission path is established;
• 2nd shows a cross-sectional view through an adjusting device;
• 3rd 2 shows a representation of a temperature control system with setting devices in a distribution device, thermostats and other system components,

An exemplary embodiment is described below with reference to FIG 1 described.

1 shows a return manifold 14 , on which several consumer loops 3rd of heat exchangers 30th converge. On the return manifold 14 are several adjustment devices 1 arranged which is a flow control valve 2nd for every consumer loop 3rd to a collecting channel within the return manifold 14 to adjust.

In a housing of each adjustment device 1 is a translucent housing section 43 set up. Below the translucent housing section 43 is an optical data interface 40 attached with a calculation means 8th is electrically connected. The optical data interface 40 comprises a photodiode as the simplest type of a photocell or a light-sensitive sensor 41 and an LED or a light-emitting diode as light source ( 42 ).

A smartphone 50 , this in 1 in the function of an externally manageable optical transmitter-receiver device 50 is used, has a photo camera and an LED for a photo flash function on a rear side, which is not visible in perspective in the illustration, which functions as a light-sensitive sensor 51 and as a light source 52 for the optical data interface 40 on the part of the smartphone 50 be used.

The smartphone 50 , is used by a user in a spatial overlap with the optical data interface 40 the adjusting device 1 brought so that a direct line of sight and a preferably short distance are ensured in an intermediate space. In this suitable spatial constellation there is an optical data transmission link 45 erected by the smartphone 50 to the optical data interface 40 or from the optical data interface 40 to the smartphone 50 Light pulses are sent and received. Comparable to optical Morse codes, the light impulses are one in relation to an on time and an off time Base frequency clocked, whereby a binary transmission signal is generated.

A program for data processing a coding between the light pulses and the data to be transmitted as well as other user interfaces and functions are as an application of a smartphone 50 provided, which is downloaded from a server. In this context, data or software updates provided on the server can also be accessed via the smartphone 50 on an adjusting device 1 are transmitted, or vice versa, data from an operation of a temperature control system 10th on the smartphone 50 be passed on to a manufacturer or service provider in a targeted and conscious manner. In the same way, a functional extension of the control in the setting device 1 be activated, or a fault diagnosis, a free parameterization, a data collection or another analysis on the setting device 1 be made.

Below is the 2nd to 4th Regarding a suitable technique of the adjustment device 1 taken, which is primarily the implementation of a control operation of the flow control valve 2nd in the tempering system 10th concerns, and is the subject of a subsidiary claim.

The adjustment device 1 is on a flow control valve 2nd assembled. The adjustment device 1 is by means of a flange 27 at the flow control valve 2nd attached. The flow control valve 2nd is in turn in the embodiment shown here in a return manifold 14 built-in. The return manifold 14 has a connector screwed into it 18th on that the return manifold 14 with a consumer loop, not shown 3rd connects. The flow control valve 2nd can also be otherwise in the return manifold 14 be installed. The connector 18th can in the return manifold 14 also be pressed, glued, soldered, welded or otherwise attached.

The adjustment device 1 comprises an electrically controllable actuator 6 . In the present example, the longitudinal axis of the adjusting device falls 1 and the actuator 6 together. The electrically controllable actuator 6 contains an actuating means movable in the axial direction 20th . The longitudinal axis of the actuator 20th also coincides with the longitudinal axis of the electrically controllable actuator 6 together. The actuator 20th is within the electrically controllable actuator 6 arranged, has a length-adjustable component in the axial direction 21 , for example an expansion element 21 , in particular a wax cartridge, and is by a coaxially arranged concentrically arranged coil spring 22 biased. The length-adjustable component 21 can also be designed as an electrical mini actuator, although these are often not considered for reasons of cost and the suspected noise level. Instead of the spiral spring 22 can also generate another suitable means, for example a ring spring assembly or the like, a bias.

Through electrical lines 7 receives the electrically controllable actuator 6 Signals from a temperature sensor, not shown, on the return manifold 14 with regard to the return temperature on the outlet side T _rewind of the flowing heat transfer medium. The electrically controllable actuator 6 receives over the lines 7 also temperature signals from a temperature sensor on the flow distributor, not shown here, with regard to an inlet-side flow temperature T _forward of the flowing heat transfer medium. Another electrical line 9 forms an interface in the present embodiment 9 to an in 2nd thermostat, not shown 12th .

In the adjustment device 1 included calculation means 8th process them over the lines 7 and 9 received signals and give to the electrically controllable actuator 6 appropriate commands or control signals from which the expansion element 21 in the actuating means 20th is activated or deactivated. This ultimately results in a defined adjustment path or stroke of the actuating means 20th realized in the axial direction. The actuating means presses 20th in the axial direction on an actuating pin 23 of the flow control valve 2nd and thereby operates the same. In the present embodiment, the longitudinal axis of the actuating means falls 20th and the actuating pin 23 as well as the flow control valve 2nd together.

Via the axial actuation of the valve pin 23 is a in the exemplary embodiment as a valve plate 24th trained valve head from a valve seat 25th lifted off and thus defines a valve position that corresponds to a specific opening position of the flow control valve 2nd or corresponds to a specific valve opening cross-section.

The respective stroke of the flow control valve 2nd or the resulting opening cross-section is via a position detection means 15 in the adjustment device 1 detected. The position detection means 15 consists of a magnet in the present embodiment 16 which has a radially outward jib 26 the electrically controllable actuator 6 assigned and with the actuating means 20th connected is. This is how the magnet moves 16 in the axial direction parallel to the expansion element 21 or parallel to the valve plate 24th , makes the same stroke or adjustment path with them, and serves as a reference for the respective stroke. A magnet 16 across from arranged Hall sensor 17th is another component of the position detection means 15 . With the Hall sensor 17th the position as well as the movement or the stroke of the magnet 16 recorded and the stroke of the valve plate 24th opposite the valve seat 25th or the cross section of the flow control valve 2nd certainly.

In the 2nd shown adjusting device 1 is in multiple copies in the in 3rd explained temperature control system 10th installed. The exemplary embodiment of the temperature control system 10th according to 3rd contains a distribution device 11 with three adjustment devices 1 using the respective flange 27 on the assigned flow control valve 2nd are mounted. The respective flow valves 2nd are in a return manifold 14 built-in. On the opposite side of the adjuster 1 or on the underside of the return manifold viewed in the installation direction 14 each has a connector 18th on which the connection to the respective consumer loop 3rd is made. The respective consumer loop forms 3rd a respective heat exchanger 30th out. On the connector 18th is a temperature detection means 7 , for example a return temperature sensor 7b , attached, in particular clipped on or glued on. With the return temperature sensor 7b is the respective return temperature on the output side T _rewind through the respective consumer loop 3rd flowing heat carrier detected. The return temperature sensor 7b could also be attached to another suitable location for recording the respective return temperature, for example immediately after the connection piece 18th on the pipe wall of the linear consumer loop 3rd .

The temperature control system 10th also has a flow distributor 13 on. The flow distributor 13 includes three fittings in the exemplary embodiment 28 for the three consumer loops shown 3rd . A means of temperature measurement 7 is again on every connector 28 attached, for example a flow temperature sensor 7a to the respective inlet-side flow temperature T flow through the respective consumer loop 3rd flowing heat carrier to detect. The flow temperature sensor 7a could also be attached to another suitable location for recording the respective flow temperature, for example immediately after the connection piece 28 on the pipe wall of the linear consumer loop 3rd .

The flow distributor 13 is with the return manifold 14 over a line 29 connected which is a tempering source 4th and a pump 5 contains. With the pump 5 can be the liquid heat transfer medium from the temperature control source 4th was charged with thermal energy or cooled, if necessary, circulated. The heat transfer medium flows through the pump 5 to the flow distributor 13 transported, there the heat transfer medium flows into the three consumer loops shown here 3rd and through this to the return manifold 14 back, the respective flow rate through the flow cross section of the respective flow control valve 2nd that in the return manifold 14 are installed, is determined. From the return manifold 14 then flows through the flowing heat transfer medium back to the pump 5 or to the temperature control source 4th .

One of the respective consumer loop 3rd associated thermostat 12th outputs a control signal when there is a need for temperature control. The control signal is from the thermostat 12th for example via an interface 9 , here a cable to the adjustment device 1 transfer. the interface 9 but could also be designed as a wireless connection. The respective setting device 1 determined by means of the respective calculation means 8th depending on the activation signal or deactivation signal of the respective thermostat 12th and the respectively assigned signals or data of the flow and return temperatures the respective opening cross section of the respective flow control valve 2nd .

The one in the temperature control system 10th according to 3rd built-in adjustment devices 1 according to 2nd are in 4th once again illustrated in a block diagram that shows the system components for self-regulation.

Heat or cold are from the consumer loop 3rd released to the environment. A thermostat 12th , in particular a room thermostat in a living room of a building, emits a signal. The signal from the thermostat 12th becomes an ECU of the adjusting device 1 to hand over. The ECU also receives temperature signals or data, such as the return temperature T _rewind and the flow temperature TVorlauf. A means of calculation 8th , which contains the ECU, is set up to electrically control the actuator, not shown here 6 the adjusting device 1 to achieve a stroke of the valve, or the predetermined opening position of the flow control valve assigned to a specific flow cross section 2nd adjust.

The opening cross section of the valve 2nd or its stroke is based on a control difference ΔT _{control difference} calculated, the control difference to be calculated ΔT _{control difference} between a temperature difference ΔT _actual from the recorded inlet temperature Tfeed and the outlet side return temperature T _rewind and a predetermined temperature spread ΔT _target from the return temperature on the outlet side T _rewind to the inlet temperature on the inlet side T _forward is formed.

The adjustment device 1 further comprises a time recording means, not shown here, and a storage means, which are set up to record a previous or current activation duration of the activation signal from the thermostat 12th and / or to record and store a deactivation period between two activations or deactivations, the calculation means 8th is set up with the ECU contained therein, the temperature spread ΔT _target variable based on an activation period and / or a deactivation period.

Alternative aspects to the execution of the appropriate technique

Below are other aspects and alternatives of the adjustment device 1 of the process or a corresponding temperature control system 10th and assemblies of the same.

The thermostat 12th of the temperature control system 10th , which is arranged in a room, an input means for entering a value, which is indicative of a predeterminable room temperature, and an interface 9 for outputting an activation signal for at least one consumer loop 3rd have in the room.

The thermostat 12th of the temperature control system 10th can be configured to respond to an actual room temperature by the thermostat 12th outputs the activation signal as long as a deviation tolerance between the specifiable room temperature and the actual room temperature is exceeded.

Activation according to the definition of the present disclosure is a switch-on state or a start-up from a standby mode of the setting device 1 or at least the calculation means 8th in the adjustment device 1 , which is supported by a continuous signal level, triggered by a signal pulse, or a control voltage or control voltage applied in the form of a signal for switching a transistor to a power supply, a power supply directly supplied in the form of a signal or the like is triggered. By definition, an activation period refers to the period from the beginning to the end of the correspondingly triggered switch-on state or the start-up from a standby mode or the reception period of a continuous signal level, control voltage, control voltage or power supply, or the time period between two signal pulses that represent a switch-on process and cause a shutdown. Deactivation and a deactivation period are accordingly the complementary state and period in which the adjustment device is not in operation 1 or at least no calculation of the calculation means 8th or control of the actuator 6 he follows.

The adjustment device 1 can be set up during an activation period by the calculation means 8th calculated electrical control to the actuator 6 output, and during a deactivation period no electrical control or a predetermined electrical control, the closed position of the flow control valve 2nd corresponds to the actuator 6 to spend. This takes place depending on the type of actuator 6 a barrier to the consumer loop 3rd after a heating process, so that excessive energy supply or overshoot of the temperature control is prevented.

The adjustment device 1 can be set up to supply electrical power to the calculation means during a deactivation period 8th and / or to the setting device 1 turn off. This saves electricity during the deactivation periods, which can also extend over a summer, for example.

The means of calculation 8th can be configured to at least one value of a previous opening position of the flow control valve 2nd to store in the storage means. As a result, when the setting device is activated 1 First a valve position is started as a starting point, which was already determined in the course of the previous heating periods and only needs to be adjusted differently in the current heating period.

The storage means can contain a previously stored reference value for the activation period and / or a previously stored reference value for the deactivation period. As a result, a period of time that has been defined as comfortable for reaching a predetermined temperature is stored as the desired reference value, according to which self-regulation is based.

The storage means can contain a previously stored range of values for the temperature spread. This can easily ensure that the operating point of the heat exchanger 30th is chosen within an energy efficient range.

The storage means can be a previously stored map with assigned values of activation times and / or deactivation times and contain predetermined temperature spreads for determining the temperature spread. As a result, a predetermined universal regulation can be implemented with less processing power.

The storage means can contain a previously stored control logic for calculating the temperature spread. This allows a more individual regulation to be implemented.

The adjustment device 1 can be set up to change the temperature spread as a function of the flow temperature, and / or the setting device 1 can be set up to change a bandwidth of the temperature spread as a function of the flow temperature, and / or the setting device 1 can be set up via the interface 9 further external signals with operating parameters from the temperature control system 10th to recieve; and the calculation means 8th be set up to adapt the temperature spread as a function of the operating parameters. This enables a control system to be implemented that detects weather fluctuations or seasons based on a change in the flow temperature and adjusts an efficient working point accordingly, or incorporates other comfort-oriented functions that can be specified on a multifunctional room thermostat into the control system.

In one room of the building you can use a thermostat 12th and two or more consumer loops 3rd or heating or cooling circuits can be arranged. This makes it possible to supply large rooms with several installed heating or cooling coils with standardized diameters and a lower overall flow resistance, which is done by means of our own setting devices 1 , but the same room thermostat can be regulated.

The thermostat 12th may have a bimetallic element that is responsive to the actual room temperature and actuates an output of the activation signal or the deactivation signal. This enables a particularly simple, reliable and cost-effective version of the room thermostat without electronics and sensors.

The activation signal or deactivation signal can be a binary signal which comprises an on state with a signal level above a predetermined level value and an off state without a signal level or a signal level below the predetermined level value. This also realizes a particularly simple and inexpensive design of the signal generation and the signal detection.

A thermostat 12th can have a microcomputer and a temperature sensor 7a , 7b include to record actual room temperature; being the thermostat 12th records and stores a curve of the actual room temperature during and / or after the activation signal or the deactivation signal is output; and the thermostat 12th and an adjusting device 1 be set up to communicate data on a course of recorded actual room temperatures. This makes the temperature control system multifunctional 10th realized, which enables an adaptive control to other comfort-oriented parameters, such as influencing a heating curve profile as a function of an initial and target temperature and / or an outside temperature or a time or the like.

The activation signal and / or the deactivation signal can be made by means of wireless interfaces from a specific thermostat 12th to an associated setting device 1 be communicated. This allows wiring from the room thermostat to the setting device 1 eliminated and an installation effort can be reduced. Furthermore, a connection between a smartphone, tablet PC or the like and an adjustment device can also be established via such a wireless interface 1 or a thermostat 12th are recorded, which enables a further input possibility for the user to the system.

A smaller temperature spread can be determined if at least one previous activation period is greater than a reference value, or a larger temperature spread can be determined if at least one previous activation period is smaller than the reference value. As a result, self-regulation is based on a period of time that has previously been defined as comfortable in order to achieve a predetermined time.

The temperature spread can be determined based on a course of successive, previous activation times. This enables a better adjustment of self-regulation to user behavior, seasons and the like.

The adjustment device 1 can be a position detection means 15 have, which is designed such a current position of the actuator 6 capture. This makes one depending on the type of actuator 6 necessary compliance with a predetermined travel path enables.

The position detection means 15 can from a magnet 16 and one the magnet 16 assigned Hall sensor 17th be educated. Thereby an exact recording and execution of a given travel range is enabled.
