Definitions

  • the present invention relates to a device for controlling a circulation of heat transfer fluid intended for temperature regulation of rooms by a centralized heat source, and in particular of premises comprising a plurality of zones each of which is individually controlled in temperature.
  • the invention finds application in the temperature regulation of habitats or workplaces with multiple rooms whose temperature can be set to a set temperature by controlling the flow of a circulating heat transfer fluid between a heat source and heat exchangers (e.g. radiators) installed in temperature controlled rooms.
  • a heat source can be used either to raise the zone temperature, in which case it provides calories operating as heating and / or to lower the temperature of the zones, in which case it allows to remove calories (i.e. to bring frigories) in operating as air conditioning.
  • the room in question is generally the main room, for example the living room in the case of a dwelling.
  • the thermostat allows to establish, possibly according to time slots, a set temperature for the room on which it depends.
  • the thermostat is associated with a temperature detector ambient in the room and acts on the heating system so as to coincide the room temperature with the set temperature.
  • This type of regulation has the advantage of simplicity but does not allow fixing separately and reliably or accurately the temperature of a set of parts of the network.
  • taps thermostats that integrate with heating radiators, either in first installation, either as a replacement for conventional taps.
  • These taps thermostats have a button, generally rotary, with means of graduated benchmarks for establishing a set temperature.
  • the valve adopts an open position allowing circulation of the heat transfer fluid in the radiator - or a set of radiators - on the bypass at which it is located. Conversely, the valve closes by itself when the set temperature is reached.
  • the present invention provides a device for control of a heat transfer fluid circulation system comprising a plurality tracks, each associated with a temperature controlled area by means thermostat controls to establish a set temperature for their respective areas.
  • thermostatic control means are programmable to record a plurality of set temperatures, each being associated with a specific setting level.
  • This device is characterized in that it further comprises means for master control allowing a first mode in which the level of adjustment for each temperature controlled zone is determined by the control means respective thermostatic and a second mode in which the setting level for each temperature controlled zone is determined by said control means master.
  • the adjustment levels of the control means thermostats can be selected manually and / or by programming.
  • control means thermostats and the master control means are adapted to make control the flow of the heat transfer fluid on the respective channels by means of a centralized control unit which controls the activation of solenoid valves supplying said respective channels.
  • the plurality of set temperatures corresponding to setting levels specific may include at least: a “comfort” level, an “economic” level for which the set temperature is respectively lower or higher than the setpoint temperature for the "comfort” level depending on whether the coolant is used to heating or air conditioning said zones (P1-P4), and a "frost-free" level.
  • control means thermostats are connected to said centralized control unit over the air.
  • the master control means transmit to said unit centralized control of information on its operating mode.
  • this transmission is carried out by hertzian way.
  • the embodiment of the present invention will be described in the context of a heat transfer fluid circulation system - water in this case - allowing both the heating and the air conditioning of a room, such as a dwelling, comprising several P1-P4 parts independently controlled by control units respective thermostats 2a-2d.
  • the system comprises four units of thermostatic controls 2a, 2b, 2c and 2d, each arranged in a room respective P1 to P4.
  • Each thermostatic control unit 2a-2d is connected to a central unit control 4 which controls, by means of a set of solenoid valves 6a-6d, the circulation of heat transfer fluid to each of the parts under control P1-P4.
  • Unity control unit 4 associates each electrostatic control unit 2a-2d with a solenoid valve respective 6a-6d which regulates the circulation of the heat transfer fluid towards the part corresponding P1-P4 by a specific route 8a-8d.
  • Channels 8a-8d are taken bypass to the respective parts P1-P4 from a main conduit 10. This the latter is mounted in a closed circuit with a heating and / or refrigeration appliance 12 and a pump 14 for circulation of the heat transfer fluid.
  • the device further comprises a master control block 16, also connected the central unit, and whose role is to impose a mode of operation on the system, as will be explained later.
  • the communication between the central processing unit control 4 and each of the thermostatic control units 2a-2d on the one hand and the master control unit 16 on the other hand is produced by radio.
  • each of the aforementioned organs is provided with transmitter / receiver means connected to Respective antennas 18, allowing wireless intercommunication.
  • thermostats 2a-2d are in the form of housings can be placed close at hand.
  • the master control unit 16 is also in the form of a housing and is normally installed either in the main room where there is a control unit thermostatic 2, either outside of the rooms under control, for example in a hallway or hallway of the habitat.
  • It has a dial 28 allowing the selection of the adjustment levels, at like the wheel 24 of the boxes of the thermostatic control units 2a to 2d.
  • This wheel 28 also allows the selection of a so-called "automatic" mode in which the master control unit 16 gives control to the different control units thermostats 2a-2d.
  • the boxes of the control units thermostatic 2a-2d and the master control unit 16 integrate the antennas 18 to within the housing and their own power source, for example in the form of a battery rechargeable, to make them autonomous.
  • the central control unit 4 is located in a nearby technical space solenoid valves 6a-6d.
  • FIG. 2 also shows a technical box 20 connecting in particular the central control unit 4 to each of the solenoid valves respective 6a-6d.
  • This box provides, among other things, the supply and control of solenoid valves according to the different commands transmitted by the central unit of command 4.
  • Each 2a-2d thermostatic control unit is programmed with its own set temperature values for each setting level, these values can be different between them for a considered level.
  • a control unit located in a room may have a temperature of setpoint of only 17 ° C for the comfort level and a temperature of 14 ° C for the level of economic adjustment while a control unit located in a living room may have set temperatures of 20 ° C and 18 ° C respectively.
  • each thermostatic control unit 2a-2d includes means for programming the desired adjustment level over time. This functionality allows the user to switch them from a setting level to a other at selected times of the day or night. For example, a unit of thermostatic control 2a-2d can be programmed to go into mode "comfort” (imposing on the thermostat the set temperature programmed for this mode) for a period of the day during which a presence in the room is highly likely, and to switch to "economic" mode during other periods day or night.
  • the time delay required for this function can be carried out by a time integrated in each thermostatic control unit, or by a system centralized, located for example within the central control unit 4.
  • Each thermostatic control unit 2a-2d further includes a probe which allows the room temperature P1-P4 to be determined at any time in which she is.
  • the master control unit 16 When the master control unit 16 is put into operating mode "automatic" by the wheel 28, it allows each of the control units to act thermostats 2a-2d according to their programmed setting state. In other words, the master control unit 16 ceases to play an active role in the operation of the system when put in "automatic" mode.
  • each room can be put in a given mode ("comfort”, “economical” or “frost-free") independently of the other parts by selecting the corresponding modes on the respective dials 26 of the control units thermostatic 2a-2d or according to the evolution of the programmed time delay.
  • the master control unit 16 when the master control unit 16 is put out of the mode "automatic” it enters one of the four aforementioned adjustment levels: “comfort”, “economical”, “frost-free” and “off”, depending on the position of the wheel 28.
  • the setting level for each temperature controlled zone is determined by the mode selected on the master control block 16, whatever the level of setting in which the thermostatic control units 2a-2d are or are bets.
  • the central control unit 4 receives this data and in response controls the solenoid valves 6a-6d so as to make the setpoint temperature coincide current considered with room temperature, as detected by the probe cited above.
  • each of the transmitters integrated into the control units respective thermostats 2a-2d and the receiver at the central unit of command 4 use a radio communication protocol.
  • the transmitters are programmed in cyclic transmission mode over a determined period, which is example equal to 9 minutes in the example considered with regard to the transmission of temperature, and 30 minutes for emission of temperatures from setpoint and comfort level.
  • This information is also transmitted systematically on each scheduled state change (for example a setting level change) within a thermostatic control unit 2a-2d by a user.
  • the master control block 16 transmits periodically to the unit control unit 4 its own programming data, and in particular the mode selected on the dial 28.
  • the central control unit 4 calculates the four regulations for the respective channels 8a-8d of fluid circulation coolant.
  • the time bases of the regulations are synchronous, that is to say that all the solenoid valves 6a-6d open simultaneously.
  • the central control unit 4 installed in the room, thus makes it possible to check the control status of the four channels 8a-8d thanks to an on / off indicator 30 (Fig. 2) and configure a transmitter on a channel using a configuration procedure standard (configuration mode and test mode).
  • a transmitter of a thermostatic control unit 2a-2d does not can only be configured on a single wireless channel.
  • the central control unit 4 is connected by a wired link 32 to the housing technique 20 installed near the manifold equipped with different solenoid valves 6a-6d.
  • the technical box 20 ensures inter alia the activation of the solenoid valves 6a-6d by a voltage of 230 volts or 24 volts depending on the model used.
  • the heat transfer fluid system can be used either for heating or for air conditioning. Also, two regulations are made on each channel: heating and air conditioning.
  • the current installation mode (“hot” or “cold”) is indicated on an entry of 230 volts from the technical box 20.
  • the central heating unit 12, 14 is used only for regulation in "hot” mode. It is always on if at least one solenoid valve 6a-6d is opened.
  • the present invention allows many variants depending on the installations considered and is in no way limited to the examples given in the embodiment described.
  • the number of order (and therefore of temperature-controlled parts) can be variable depending on the needs.
  • the parameters mentioned can be adapted to the different cases of use.
  • the present invention can be implemented in heating without possibility of air conditioning by circulation of cooled water.
