    [0001] The present invention relates to a system for regulating the temperature and the purification of ambient air in a building, as well as a method of controlling a room temperature. such a system. Ambient air in a building is subject to specific pollution from many sources of pollutants. The provisions relating to the energy performance of buildings, according to Directive 2010/31 / EU of the European Parliament and of the Council of 19 May 2010, require measures to ensure the energy performance of buildings. One of the consequences is the construction of buildings increasingly airtight, for which the renewal of the air may not be enough to guarantee a healthy ambient air, especially in the presence of sources emitting pollutants. Air quality is a public health issue requiring the use of air purifiers. It is known to treat pollution by ventilation. The rate of ventilation and / or extraction of the polluted ambient air is adapted according to the concentration of pollutant. The clearance is ensured by the renewal of the air and / or the extraction of the polluted air, so that the pollutants are not eliminated. The concentration of pollutants decreases following the intake of fresh air. To eliminate pollutants, it is known to equip the air handling units with particulate filters that retain dust from fresh air renewal, and if necessary from recycled air. Other known plants are equipped with pollution control systems intended to eliminate chemical or biological pollutants, for example systems using cold plasma, the combination of active carbon absorption and photocatalysis, or the combination of cold plasma and photocatalysis. Moreover, the treatment of pollution by ventilation is independent of the regulation of the ambient air temperature, which is provided by an additional system, for example a fan coil or a heat pump.
    [0002] In known systems, the treatment of pollution by filtration or purification is independent of the problem of controlling the temperature of the ambient air, which it is necessary to regulate elsewhere. It is these drawbacks that the invention more particularly intends to remedy by proposing a combined system for regulating the temperature and cleaning the ambient air in a building.
    [0003] To this end, the subject of the invention is a system for regulating the temperature and cleaning the ambient air in a building, comprising: at least one thermal transmitter comprising means for moving the ambient air and heat exchange means between the ambient air and a heat transfer fluid circuit, a heat transfer fluid flow control valve, means for measuring the ambient air temperature, a purification device for the heat exchange fluid, ambient air, means for detecting the concentration of at least one pollutant in the air, a control unit able to control the activation of the means for moving the ambient air, the valve and the purification device according to the ambient air temperature and the pollutant concentration in the ambient air. Thanks to the invention, the system makes it possible to ensure both thermal comfort and control of pollution, depending on the thermal need and the pollutant limit concentration. According to advantageous but non-obligatory aspects of the invention, such a system may include one or more of the following features, taken in any technically permissible combination: The intensity of the ambient air cleaning device is a function of the intensity of the means for moving the ambient air. - The purification device includes a particulate filter capable of retaining particulate pollutants. The purification device includes at least one purification module capable of treating chemical or biological pollutants. - The heat emitter is a fan coil unit including a fan motor unit. Another aspect of the invention relates to a method of controlling such a system for controlling temperature and purifying ambient air in a building, characterized in that it comprises steps in which: a) the control unit adjusts the opening of the valve and the intensity of the means for moving the ambient air according to the result of the comparison between the ambient temperature and a set temperature, b) the control unit controls the activation of the purification device according to the result of the comparison between the pollutant concentration in the ambient air and a limiting concentration.
    [0004] According to advantageous but non-mandatory aspects of the invention, such a method may include one or more of the following features, taken in any technically permissible combination: Steps a) and b) are successive. 5 - When the pollutant concentration in the ambient air is greater than a limiting concentration, the control unit activates the purification device for a predetermined duration. The heat emitter is a fan coil comprising a motor-fan unit, and the control unit is able to adjust the intensity of the fan motor unit according to several increasing speeds which represent a configurable percentage of the maximum speed of the fan. rotation of the means for moving the ambient air. - The control unit is able to modulate the opening rate of the valve according to several increasing rates of opening of the valve, which represent a configurable percentage of the maximum opening of the valve.
    [0005] The invention will be better understood and other aspects thereof will be better understood in the light of the following description of a temperature control system and purification of ambient air in a building, as well as than a method for controlling such a system in accordance with its principle, given solely by way of example and with reference to the appended drawings, in which: FIG. 1 is a diagram of a control system conforming to FIG. invention; Figure 2 is a block diagram of a control method of the system of Figure 1; Figure 3 is a graph showing the evolution of the speed of rotation of a fan of the system, according to the thermal energy requirements.
    [0006] The system for regulating the temperature and cleaning of the ambient air in a building B according to the present invention is represented in FIG. 1 and comprises at least one heat emitter 10 able to regulate the temperature of the ambient air, that is, to warm or cool the air. For example, it may be a fan coil comprising means 11 for moving ambient air, for example a motor-fan unit comprising a motor 111 actuating a fan 112 able to circulate the fan. air against heat exchange means 12 air / water between the ambient air and a coolant circuit 13, for example one or more exchange batteries. The heat transfer fluid is able to be heated and / or cooled by a heating and / or cooling unit 14, for example a heat pump, in particular a reversible heat pump. The coolant may be water, optionally additivée.
    [0007] When the fan motor unit 11 is activated, the ambient air is sucked into contact with the exchange battery 12, which increases or decreases the ambient air temperature, depending on whether the heat pump 14 is operating in the operating mode. heating and / or cooling. The air is then diffused in the building B through a diffusion member 15. The motor-fan unit 11 can operate with several rotation speeds, for example three rotation speeds, namely a first low speed V1 limiting acoustic nuisance, a second speed or average speed V2 ensuring a level of average thermal comfort while limiting the acoustic discomfort, and a third speed 10 or high speed V3 to condition the room temperature very quickly, to the detriment of acoustic comfort. The speeds V1, V2 and V3 are increasing and not zero, and represent a configurable percentage of the maximum speed of rotation of the fan 112. VO is a zero speed of the fan 112.
    [0008] The function of the fan 112 is to force the movement of the ambient air in the heat emitter 10, and does not ensure the renewal of the ambient air, referred to as the "ventilation" use. Alternatively, the fan coil 10 is replaced by an indoor air conditioning unit.
    [0009] An ambient air cleaning device 20 is incorporated in the system. For example, it may be a particulate filter capable of retaining particulate pollutants. Alternatively, it may be a purification module capable of treating chemical and / or biological pollutants, or a combination of several of these purification devices. For example, chemical and / or biological pollutants can be removed by a cold plasma system, or the combination of activated carbon adsorption and photocatalysis. Alternatively, it may be a system using the combination of cold plasma and photocatalysis. Means for measuring the pollutant concentration in the ambient air include at least one pollution sensor measuring a concentration P of specific pollutant, for example the particle concentration when it is a particulate sensor, the concentration of chemical compound, especially formaldehyde benzene or styrene when it is a chemical sensor, or a microbiological pollutant, such as a virus, a fungus or a bacterium, when it is a biological sensor. A control unit 50 is able to control the thermal transmitter 10 as a function of the temperature difference between a set temperature Tc programmed in a memory of the control unit 50, and the temperature T of the ambient air, measured by 3022615 5 means for measuring the ambient air temperature, for example a temperature sensor 40. The control unit 50 is also able to control the purification device 20, depending on the difference between the pollutant concentration P and a pollutant-limiting concentration Pc, programmed in the memory of the control unit 50. The thermal energy requirement of the building B is proportional to the flow rate of the coolant 13 of the heat emitter 10. A Flow control valve 60 is controlled by the control unit 50, depending on the difference between the temperatures Tc and T, for heating or cooling the ambient air.
    [0010] The intensity of the ambient air purification device is a function of the intensity of the fan 112. In fact, the higher the fan speed 112 and the greater the volume of air treated by the purification device. 20 is important. The remainder of the description relates to a method for controlling the system for regulating temperature and purifying ambient air in building B, shown in FIG. 1. This is a multi-criteria control to ensure thermal comfort and to control the pollution according to the thermal need and the limit concentration in pollutant Pc. In a first step 1, the control unit 50 compares the ambient temperature Ta of the building with the set temperature Tc.
    [0011] In a second step 2 and when the ambient temperature T is different from the set temperature Tc, then the control unit 50 actuates the valve 60 to regulate the flow of the coolant 13. In this step 2, the unit of control modulates the opening ratio M of the valve 60 as a function of the difference between the ambient temperature T and the set temperature 25 Tc. The valve 60 is open to the maximum when the need for thermal energy is very important, and it is partially open or closed, when the need is low or zero. The graph of FIG. 3 shows the evolution of the speed V of the fan, in rpm, as a function of the opening ratio M of the valve 60, expressed as a percentage. MO, M1, M2, M3 and M4 are denoted by five increasing rates of the opening M of the valve 60, which represent a configurable percentage of the maximum aperture. The rates MO to M4 are proportional to the levels of the thermal energy requirement of the building B. The levels MO to M4 are respectively equal to 0% and 100%. For example, the rate M1 is equal to 25%, M2 to 50% and M3 to 75%. Curve C1, shown in broken line between points A and D, corresponds to the progressive opening of valve 60, when a supply of hot or cold heat energy is necessary to heat or cool the ambient air. Building B, depending on whether the system is operating in heating or cooling mode. Let A be a first operating point, for which the speed V of the fan 112 is equal to VO and the opening rate of the valve is equal to the rate M1. When the opening rate M of the valve 60 exceeds the rate M1, the control unit 50 drives the fan to go from a low speed V1 to a second operating point B to ensure comfort. thermal while limiting the acoustic discomfort. As long as the opening rate M of the valve 60 is between M1 and M3, the fan 112 remains at a low speed V1.
    [0012] When the opening ratio M of the valve 60 exceeds M3, the fan 112 switches to the average speed V2, as shown at the operating point C. As long as the opening ratio M of the valve is between M3 and M4, the fan 112 remains at medium speed V2. As soon as it is necessary to provide additional thermal energy, the fan 112 switches to high speed V3, as shown at the operating point D. The curve C2, shown in bold line between the points D and G, corresponds the progressive closure of the valve 60, in the case of a surplus of thermal energy in the building B, that is to say when the air is too hot compared to the setpoint temperature Tc and that the system operates in heating mode, or when the air is too cold compared to the set temperature Tc and the system is operating in cooling mode. At the operating point D and as the opening rate M of the valve 60 remains between M3 and M4, the fan 112 remains at high speed V3.
    [0013] As soon as the opening ratio M falls below M3, the control unit 50 drives the fan 112 so that it switches to medium speed V2 at an operating point E whose parameters are identical to those of the point As long as the opening rate M of the valve 60 is between M2 and M3, the fan 112 remains at the average speed V2. When the opening rate M of the valve 60 passes below M2, the fan 112 goes into low speed V1, as shown at the operating point F. As long as the opening ratio M of the valve 60 is between and M1, the fan 112 remains at low speed V1.
    [0014] When the thermal energy surplus is canceled, the valve 60 changes to the open rate MO.
    [0015] At the end of steps 1 and 2, the opening ratio M of the valve 60 is adjusted in accordance with the heating or cooling requirements of the building B. The following method enables the intensity of the device to be adjusted. purification according to the concentration of pollutant P.
    [0016] In a third step 3 following steps 1 and 2, the control unit 50 compares the pollution level P with the pollutant limit concentration Pc. When the pollutant concentration P is lower than the limiting concentration Pc, the control unit 50 again activates the first step 1 without affecting the state of the purification device 20.
    [0017] When the pollution level P is greater than the limiting concentration Pc, the control unit 50 activates a fourth step 4. In the fourth step 4, when the purification device 20 is inactive, the active control unit 50 a fifth step 5 in which the control unit 50 activates the purification device 20 for a first predetermined duration D1, for example 3 15 min. Thus, the concentration P decreases, which improves the quality of the air. A sixth step 6 is activated when, in the fourth step 4, the purification device 20 is active. The sixth step is also activated at the end of the activation time D1 of the purification device, at the end of the fifth step 5. In the sixth step 6, the control unit 50 compares the speed V of the fan 20 112 with the average speed V2. When the speed V is lower than the average speed V2, a seventh step 7 is activated, in which the control unit 50 activates the average speed V2 of the fan 112 for a second predetermined duration D2, for example 3 minutes. When the speed V is greater than or equal to the average speed V2, the control unit 50 does not change the speed V.
    [0018] At the end of steps 1 to 7, the control unit 50 again activates the first step 1. The steps 1 to 7 are repeated in a loop. Alternatively, the fan coil 10 is replaced by an indoor air conditioning unit. In the context of the invention, the different variants can be combined with each other.
