Definitions
- the present invention relates to a control device of a control system circulation of coolant intended for the regulation of space temperature by a centralized heat source, and in particular rooms having a plurality of zones each of which is individually controlled in temperature.
- the invention finds application in the regulation of temperature of habitats or workplaces with multiple rooms whose temperature can be set to a set temperature by controlling the flow rate of a circulating coolant between a heat source and heat exchangers (eg radiators) installed in temperature controlled rooms.
- a source of heat can be used either to raise the temperature zones, in which case it can bring calories in functioning as heating and / or for lowering the temperature of the zones, in which case it allows to remove calories (i.e. to bring frigories) in functioning as air conditioning.
- the room in question is usually the main room, by 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 the room on which it depends.
- the thermostat is associated with a temperature sensor ambient in the room and acts on the heating system so as to make it coincide the temperature of the room with the set temperature.
- This type of regulation has the advantage of simplicity but does not allow to fix separately and reliably or accurately the temperature of a set of parts of the network.
- faucets thermostats that integrate with heating radiators, either in the first installation, or to replace conventional faucets.
- These faucets thermostatic devices have a button, generally rotary, with means of graduated markers to establish a set temperature.
- the faucet adopts an open position allowing the circulation of the coolant in the radiator - or a set of radiators - on the bypass at which it is located.
- the valve closes by itself when the set temperature is reached.
- control systems of a plant of air conditioning which comprise a plurality of channels each associated with a zone controlled in temperature.
- An example of such a system is described in EP-A-559 600. It comprises thermostatic control means, said slaves, to measure the ambient temperature and establish temperatures of instructions for their respective zones, thermostatic control means master and a centralized control unit which, on the basis of the signals received from said thermostatic control means and said master control means, controls the flow of air on said air supply channels.
- the present invention proposes a control system of a heat transfer fluid circulation system such as the one mentioned above but which comprises the means set forth in the feature of claim 1.
- the embodiment of the present invention will be described in the context of a heat transfer fluid circulation system - water in this case - allowing heating as well as 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 has four units of thermostatic control 2a, 2b, 2c and 2d, each being arranged in a room respective P1 to P4.
- Each thermostatic control unit 2a-2d is connected to a central unit 4 which controls, through a set of solenoid valves 6a-6d, the circulation of heat transfer fluid to each of the rooms under control P1-P4.
- the unit Central 4 associates each electrostatic control unit 2a-2d with a solenoid valve 6a-6d which regulates the circulation of the heat transfer fluid to the room corresponding P1-P4 by a specific route 8a-8d.
- Channels 8a-8d are taken in branching to the respective pieces P1-P4 from a main duct 10. This last is mounted in a closed circuit with a heating and / or refrigeration device 12 and a pump 14 for circulating the coolant.
- the device further comprises a master control block 16, also connected at 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 unit of control 4 and each of the thermostatic control units 2a-2d on the one hand and the master control block 16 on the other hand is performed by radio.
- each of the aforementioned organs is provided with transmitter / receiver means connected to respective antennas 18, allowing wireless intercommunication.
- control units of 2a-2d thermostats are in the form of housings can be arranged at your fingertips.
- the master control block 16 is also in the form of a housing and is normally installed either in the main room where a control unit is located thermostatic 2, or outside the controlled rooms, for example in a vestibule or a corridor of the habitat.
- It comprises a wheel 28 allowing the selection of the adjustment levels, to like the knob 24 of the housings 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 block 16 makes the control to the different control units thermostatic 2a-2d.
- the enclosures of the control units thermostatic 2a-2d and the master control block 16 integrate the antennas 18 to within the housing and their own power source, for example in the form of battery rechargeable, to make them autonomous.
- the central control unit 4 is located in a nearby technical space solenoid valves 6a-6d.
- FIG. 2 further shows a technical housing 20 connecting in particular the central control unit 4 to each of the solenoid valves respectively 6a-6d.
- This housing ensures, among other things, the supply and control of solenoid valves according to the different commands transmitted by the central unit of order 4.
- Each thermostatic control unit 2a-2d is programmed with its own set temperature values for each level of adjustment, these values that may be different from each other for a given level. For example, 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 a set temperature of 20 ° C and 18 ° C, respectively.
- each thermostatic control unit 2a-2d has means for programming in time the desired level of adjustment. This feature allows the user to move 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 "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 probable, and to switch to "economic" mode during the other periods of the day or the night.
- the time required for this function can be performed by a database of integrated time 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 comprises a probe which allows to determine at any time the room temperature of the room P1-P4 in which she is.
- the master control block 16 When the master control block 16 is put in operating mode "automatic" by the wheel 28, it lets act each of the control units thermostatic 2a-2d according to their programmed parameter state. In other words, the master control block 16 stops playing an active role in the operation of the system when it is put in the "automatic" mode.
- each piece can be put in a given mode ("comfort”, “economic” or “frost-free") independently of other parts by selecting the corresponding modes on the respective knobs 26 of the control units thermostatic 2a-2d or according to the evolution of the programmed delay.
- the master control block 16 when the master control block 16 is put out of mode "automatic" it enters one of the four levels of adjustment mentioned above: “comfort”, “economy”, “frost” and “stop”, depending on the position of the knob 28.
- the setting level for each temperature controlled zone is determined by the mode selected on the master 16 control block, regardless of the level of setting in which the thermostatic control units 2a-2d are located or are updates.
- Each of the thermostatic control units 2a-2d - which are in number of four in the example considered - periodically transmits three parameters to the central control unit 4 via its antenna 18: i) the set temperatures to assign to each level of adjustment ("comfort”, "economic” and “frost"), ii) the room temperature at the time, and iii) the level of adjustment at the time considered.
- the central control unit 4 receives these data and drives in response the solenoid valves 6a-6d so as to match the set temperature of the level current considered with the temperature of the room, as detected by the probe supra.
- 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. Issuers are programmed in cyclical transmission mode over a specified period, which is example equal to 9 minutes in the example considered with regard to the emission of temperature, and 30 minutes with regard to the emission of temperatures of setpoint and comfort level. This information is also transmitted systematically on each programmed change of state (for example a change of setting level) within a thermostatic control unit 2a-2d by a user.
- the master control block 16 transmits periodically to the unit central control 4 its own programming data, and in particular the mode selected on wheel 28.
- the central control unit 4 calculates the four regulations for the respective fluid circulation channels 8a-8d coolant.
- the time bases of the regulations are synchronous, that is to say that the opening of all the solenoid valves 6a-6d operates simultaneously.
- the central control unit 4 installed in the environment, thus makes it possible to verify the control status of the four channels 8a-8d by means of an on / off indicator light 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 be configured only on a single wireless channel.
- the central control unit 4 is connected by a wired connection 32 to the housing technique 20 installed near the manifold equipped with different solenoid valves 6a-6d.
- the technical housing 20 ensures inter alia the activation of 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 for either heating or air conditioning. Also, two Regulations are made on each lane: heating and air conditioning.
- the current installation mode (“hot” or “cold”) is indicated on an input 230 volts of the technical box 20.
- the heating unit 12, 14 is used only for the control in "hot” mode. It is still running if at least one 6a-6d solenoid valve is opened.
- the present invention allows numerous variants according to the facilities under consideration and is not limited to the examples given in the described embodiment.
- the number of control (and therefore temperature-controlled parts) can vary depending on the needs.
- the parameters mentioned can be adapted to the different cases use.
- the present invention can be implemented in systems of heating without possibility of air conditioning by circulation of cooled water.
