    SOLAR AND THERMODYNAMIC HYBRID AIR TREATMENT SYSTEM
    TECHNICAL FIELD AND OBJECT OF THE INVENTION The invention relates to the field of hybrid air conditioning and building heating systems. More specifically, the present invention aims a reversible system capable of cooling as to heat the interior volume of a building, using solar collectors coupled to a thermodynamic system, in order to ensure the dual function of air conditioning and heating with reduced energy consumption.
    STATE OF THE ART
    The general problem therefore lies in the regulation of the temperature inside buildings, typically requiring cooling in the summer and heating in winter, while inducing only a very low non-renewable energy consumption, in particular in an increasingly severe regulatory context.
    To provide air conditioning and heating buildings, the state of the art includes air treatment units, consisting of thermodynamic systems, sometimes reversible when they are able to ensure themselves the dual function.
    The known air treatment units operate mainly with thermodynamic systems with mechanical compression. These known air handling units thus use electrical energy, absorbed by a compressor, to ensure the operation of the system and regulate the building temperature.
    One advantage of these known systems lies in their recognized effectiveness. Indeed, the coefficient of performance, known by the acronym COP, defined as the ratio between the thermal power produced, understood as the cold or hot thermal power, and the electrical power absorbed, is greater than 1 and can reach values These systems represent a progression, in terms of energy saving, in comparison with the heating systems of older technologies, with electrical or combustion resistors, for which the COP will be less than or equal to 1 .
    However, energy optimization is now a major problem, particularly in the building sector, whose evolution is notably marked by the regulations in force, such as the RT 2012 standard currently in France. This regulation imposes reduced energy consumption criteria and even future standards of positive energy buildings capable of producing energy. It is therefore essential to develop building temperature control systems that comply with current regulations and anticipate the likely future even stricter regulations.
    In this general context, in order to propose air treatment systems, with a view to cooling or heating, as necessary, the interior volume of buildings, various technologies belonging to the state of the art have been developed. First, as known to those skilled in the art, the use of solar energy is a first means of meeting the regulatory requirements both in terms of energy consumption, but also in terms of energy production. Solar energy can be collected by solar panels, in the form of electrical energy, via photovoltaic cells, or thermal energy, by means of a heat vector fluid. It is possible to store this energy or use it directly.
    It should be noted that even if the production of electrical energy provides a greater versatility of use, in comparison with a production of thermal energy, its performance remains rather weak today (10% to 20%) compared to a production of thermal energy that can reach yields of the order of 80%.
    Various evolutions have thus been developed with the aim of maximizing the efficiency of photovoltaic cells. For example, EP2227694 discloses a solar energy collection device, transformed into electrical energy stored for use freely.
    However, the efficiency of photovoltaic panels remains low and limits their impact on the overall energy balance of a building.
    However, it is known that the recovery of thermal energy from solar radiation can have a much better efficiency from an energy point of view, and thermal solar panels have been developed.
    Such solar thermal collectors can recover up to 80% of the received solar power radiated, in the form of thermal energy, that is to say of heat. This captured heat can be used directly, or, more generally, stored in a buffer tank, using a heat vector fluid, for example water, and then redistributed according to the needs of the building. In fact, the storage of collected thermal energy may seem necessary to meet the heating needs of a building. However, in regions with a temperate climate like the Europe zone, solar gains during the winter period do not generally make it possible to satisfy the heating needs of a building, even in the presence of a thermal storage element. In addition, for certain industrial applications, for example to carry out industrial drying, requiring a constant need for heat, storage of thermal energy is not essential, as in the device described in WO2011146993.
    In practice, the function of heating a building using solar energy is usually done through a thermal storage device, which compensates for variations in solar radiation and optimize redistribution heat according to real needs. This thermal storage can be of several types. On the one hand, some techniques use hot water storage tanks, as described in WO2015054313. On the other hand, some techniques provide for heat storage by a liquid / solid phase change material as described in WO2011007009. The latter techniques have the advantage of having a storage capacity per unit of mass greater than water. However, they also require additional fluid media to reduce the heat of the solar panels, and redistribute it to the building.
    Furthermore, more recently, new solar collector technologies have been developed, allowing the recovery of solar energy in the form of electrical energy and in the form of thermal energy, with a view to improving the overall energy efficiency of said solar collectors.
    These panels - or solar collectors - are called "hybrid", and indeed have the advantage of synergy between photovoltaic cells, having a good yield at low temperatures and thermal cells. On the other hand, another category of technologies aimed at recovering solar energy to achieve an air conditioning function brings together the closed absorption and adsorption systems.
    Sorption is a physico-chemical phenomenon of assimilation of a gas by a liquid medium - it is called absorption - or by a solid medium - it is called adsorption. By the sorption process, it is thus possible to design a thermodynamic cycle similar to a mechanical compression refrigeration cycle. In this case, the mechanical compression is replaced by a thermal compression, in that it is necessary to provide an external thermal energy to regenerate the absorbing media. The operation of the system is then provided by a thermal energy and not mechanical or electrical. The disadvantage of this type of system is a low coefficient of performance, defined as the ratio between the cold power produced and the necessary thermal power, of the order of 0.5, against 3 or 4 for mechanical compression systems.
    In this context, recent technologies provide coupling of sorption technology and solar energy recovery, as described in WO2007063119. However, the major drawbacks of these systems reside in the need for a very large solar panel surface, particularly because of the low efficiency mentioned above, a size of the system, a high complexity of implementation and a high cost.
    In parallel with the closed sorption systems described above, there are also techniques based on open systems, called "desiccation" systems. These systems operate on the principle of desiccation (dehydration), achieved by the assimilation of water vapor contained in the air by a solid or liquid media. The system is coupled with an indirect and / or direct adiabatic cooler and an energy recuperator, for efficient cold production.
    In the same way as for open sorption systems, the desiccant material must be regenerated by heat input. Liquid desiccation systems, very complex to implement, and solid desiccation systems, using for example desiccant wheels, have been developed.
    Thus, in a context in which, for energetic, economic and ecological reasons evident from what has been described above, there is a need for an air treatment system, aimed at regulating the temperature in a building , implementing a heating function and an air conditioning function, making the best use of solar collectors and minimizing residual energy consumption.
    Indeed, the air conditioning systems using absorption or desiccation today suffer from a low coefficient of performance, of about 0.5, this coefficient of performance being defined as the ratio between the cooling power produced and the power thermal absorbed.
    In addition, for such systems to enter significantly into the energy balance of a building, they necessarily implement large areas of solar panels, inducing including significant cost and reliability undermined by the number of hydraulic connections induced .
    However, in accordance with the present invention, it has been made possible to improve the synergy between a technique for producing cold by sorption and a technique for producing solar thermal energy.
    It is known that the so-called "desiccation" systems have the main function of dehumidification of moist air. These systems therefore have a real economic meaning when the main load of the air treatment is dehumidification. In addition, the cooling function is now provided by mechanical compression air conditioning systems. Thus, in order to be able to introduce a proportion of renewable energy into an air-conditioning system, when the distribution between the dehumidification load and the cooling tends towards cooling, it can be envisaged a hybridization between the mechanical compression systems and the drying systems. using solar energy or fatal heat.
    Thus, in this context, the present invention consists in particular in the combination of a drying air conditioning unit, a thermodynamic system with mechanical compression, and a thermal or hybrid solar collector. The hybrid solar collector preferably makes it possible to recover both electricity and heat, while the drying air conditioning unit implements a regenerated desiccation wheel, in particular by virtue of the heat energy from the solar collector and of the condenser of the thermodynamic system. Usually, when the thermodynamic system operates in air conditioning, the heat rejected at its condenser is lost. The present invention thus makes it possible to revalue this energy loss and to reuse it to regenerate a desiccation wheel.
    The combination between a solar collector, a drying system and a thermodynamic circuit allows a gain on the significant power consumption, typically between 20% and 40% depending on the solar collector panel area allocated.
    GENERAL PRESENTATION OF THE INVENTION To this end, more specifically, the invention relates to an air treatment system, for cooling and heating the interior volume of a building, comprising: a solar collector, for receiving the solar energy and transform it, at least partly, into thermal energy configured to heat a fluid vector of said thermal energy, an air treatment unit, said air treatment unit comprising: a rejection stream including an inlet of air extracted from the interior volume of the building, and an exhaust air outlet to the outside, and ventilation means for creating a flow of air extracted from the interior volume of the building via the exhaust air inlet and discharged to the outside via the exit air outlet, a blowing vein having an intake of fresh air from outside the building, and a blown air outlet to the volume int building, as well as ventilation means to create a flow of air entering via the fresh air inlet and then blown to the interior volume of the building via the outlet air outlet, a drying system consisting of a drying wheel and two adiabatic humidifiers and whose function is to ensure a partial cooling of the incoming air flow, a plurality of thermodynamic equipment constituting a mechanical compression heat pump system and having the function of providing a complement for cooling the incoming air flow, and said air treatment unit having the following operating modes: in an air-conditioning operating mode of the system, the desiccant wheel belongs to the blowing duct and dehydrates the incoming air in said blowing stream, by desiccation, the adiabatic humidifiers partially cool the incoming air flow and said at least one thermodynamic cooling equipment provides additional cooling of the incoming air flow before it is blown into the interior volume of the building, the thermal energy produced by the solar collector being at least partially used to ensure the regeneration of said desiccant wheel, in a heating operation mode, the desiccant wheel and the adiabatic humidifiers are deactivated and the heat energy produced by the solar collector is at least partially used, directly or indirectly, for heating the volume interior of the building.

    DETAILED DESCRIPTION OF THE INVENTION
    It is recalled that the present invention is described below using various non-limiting embodiments and may be implemented in variants within the scope of the skilled person, also covered by this invention.
    Figure 1 describes the operation in "air conditioning" mode of the air treatment system, for cooling and heating the interior volume of a building, according to the invention. The system comprises a solar collector 1, thermal or, preferably, hybrid, that is to say capable of producing thermal energy and electrical energy from the solar energy collected. It further comprises an air treatment unit 10, able to manage the air flows in and out of the building, in order to cool or heat, as the case may be, the interior volume of the building.
    The solar collector 1 transmits the heat energy produced to a heat vector fluid, such as water for example. On the other hand, if the solar collector 1 is hybridized, the electrical energy produced can be directly consumed by the electrical equipment of the air treatment unit 10, as shown in FIGS. 3 to 5.
    The heat vector fluid, heated by the thermal energy from the solar collector 1, is conveyed, according to the embodiment of FIG. 1, to a heat storage device 4 by a hot fluid duct 3. This storage device 4 may be a water tank, or an element made of phase change materials, for example. According to this embodiment, cold fluid is the reverse path, from the storage element to the solar collector 1 via a cold water pipe 7, to be heated by the heat energy produced.
    According to one embodiment, an auxiliary heat source 6 may be disposed close to the heat storage element 4 to provide additional thermal power in case of reduced sunlight. This auxiliary source of heat 6 can be fed with energy of fossil origin (gas, fuel oil ...), fatal energy (energy losses of the building to be upgraded) or electrical energy (for example of thermodynamic origin). The air treatment unit 10 comprises: a rejection stream, including an air intake extracted from the interior volume of the building, preferably a complementary fresh air inlet, coming from the outside, and an outlet of air released outside the building; - A blowing stream, including a fresh air intake, from the outside, preferably a return air intake from the building interior volume, and a blown air outlet to the interior volume of the building.
    In "air conditioning" operating mode, the blowing stream comprises a drying wheel 13. This wheel makes it possible to dehydrate the air passing through it. This desiccation phenomenon also has the effect of slightly heating the air passing through the drying wheel 13. The air of the blowing stream is then cooled by suitable thermodynamic equipment. In the present case, the thermodynamic equipment implemented in the embodiment shown in FIG. 1 comprises an indirect adiabatic cooler, consisting of an enthalpy wheel 16 and a humidifier 19, then a direct adiabatic cooler 17. , the heat exchanger in evaporator mode 17 provides additional cooling capacity to ensure the comfort of users in the building.
    Still in the "air-conditioning" operating mode, the rejection channel comprises thermodynamic equipment, aimed in particular at promoting the regeneration of the desiccant wheel 13. These thermodynamic equipment comprise, in the embodiment represented in FIG. 1, an adiabatic cooler. indirect circuit consisting of the humidifier 19 and the enthalpy wheel 16.
    In addition, this embodiment comprises a hot water battery 15, powered by the thermal energy from the solar collector 1. This hot water coil 15 heats the air in the discharge vein. Thus, the hot water arrives at the exchanger 15 via a pipe 5 and leaves the exchanger via another pipe 9.
    In addition, a three-way valve 8 regulates the flow of hot water and therefore the thermal power supplied to the discharge air. Then, the thermodynamic exchanger 14, operating in condenser mode, ends the heating of the air in the rejection channel. Hot air arrives on the desiccant wheel to vaporize the adsorbed water. At this stage, the hotter the air, the more it has a significant hygroscopic power, that is to say an ability to recover water vapor in the drying wheel 13. In this way the hot air discharges the adsorbed water in the desiccant wheel 13 and an air cooled by the vaporization of this water, and therefore wet, is rejected externally. With regard to the hot water battery 15, it should be noted that in a "heating" operating mode, said hot battery 15, supplied by the solar collector 1, is preferably positioned in the blowing duct, in order to distribute the all the thermal energy collected from solar radiation for the heating of the building premises. On the other hand, in the "air-conditioning" operating mode, as described above, the hot battery 15 is positioned in the rejection channel to allow regeneration of the desiccant wheel 13. As a result, the system preferably comprises in this embodiment comprising a hot water coil 15, two hydraulic circuits that can be controlled via a set of three-way valves capable of placing said hot-water battery 15 in the rejection channel in "air-conditioning" operating mode and in the blowing vein in "heating" operating mode.
    It is furthermore represented, in all the figures, that the air treatment unit 10 may comprise a technical compartment 23 in which is (are) disposed (s) one or more compressor (s) 24, intended for the thermodynamic circuit, and an electrical plate 22 on which are arranged electrical control elements of the thermodynamic equipment implemented in the rejection channel or in the blowing vein.
    Furthermore, each vein has a fan, respectively 11 and 18, to create the flow of air entering the building, the inlet of the blowing duct at the outlet of the blowing duct, and the air flow rejected, between the entrance and exit of the rejection vein.
    Each vein may furthermore comprise a set of registers 12, 21, 20, 30. The function of the registers 12 and 21 is to modulate, by a system of inclination flaps, the distribution of fresh air and of return air injected into the blowing vein. Similarly, the registers 20 and 30 have the function of modulating, by a system of tilting flaps, the distribution of fresh air and additional fresh air injected into the reject vein.
    Figure 2 shows the same air handling unit 10 as Figure 1, but in a "heating" operating mode. Thus the heat exchanger 25 using the heat vector fluid heated by the thermal energy from the solar collector 1 is now in the blowing duct.
    The heated fluid, typically hot water, arrives and leaves the heat exchanger 25, respectively via the lines 5 and 9. A three-way valve 8 allows, as previously, the regulation of hot fluid flow.
    In this "heating" operating mode, the desiccant wheel 13 is deactivated and provides no function. Similarly, the humidifiers 19 and 17 are also stopped.
    Thus, in this "heating" mode of operation, the heat energy from the solar collector 1 is used to heat the interior volume of the building, via the heat exchanger 25 supplied with hot fluid, such as hot water, heated by said thermal energy. Alternatively, the heat carrier fluid may be directly used air, once heated by solar energy collected, to heat the interior volume of the building after being conveyed and ventilated in the blowing vein.
    Figures 3 to 5 show variants of the embodiment described above.
    Thus, FIG. 3 represents a system according to the invention, using air as a heat vector fluid, for transforming the solar energy received by the solar collector 1 into thermal energy. The advantage of using air as a heat carrier fluid lies in the greater reactivity obtained from the solar collector 1. In return, however, the solar collector 1 must preferably be placed in the immediate vicinity of the treatment unit. air 10, to limit the heat loss greater with air than with water for example, the air with a low thermal inertia.
    In this embodiment, there is naturally no storage element or hot water coil as in FIGS. 1 and 2.
    In contrast, according to the embodiment shown in FIG. 3, the system comprises a thermal energy recovery box 28 comprising heat recovery means 29, such as an enthalpy wheel or a plate heat exchanger for example . The thermal energy thus recovered is able to be conveyed to the rejection stream, to promote the regeneration of the desiccant wheel 13 in the "air conditioning" operating mode. In "heating" operating mode, the thermal energy thus recovered makes it possible to increase the evaporation temperature of the evaporator 14 and thus to improve the thermodynamic performance coefficient (COP) of the system.
    FIG. 4 represents an embodiment similar to that of FIG. 3, in which the air, acting as a heat vector fluid, flowing in the solar collector 1, does not flow in a closed circuit as in FIG. 3. On the contrary, as shown in Figure 4, according to this embodiment, the air inlet 27 of the solar collector 1 is open to the outside environment. The heat exchange between the solar collector 1 and the air treatment unit 10 is carried out, as in FIG. 3, by a heat exchanger 29, which may be a rotary exchanger, a plate exchanger, or a heat pipe by example.
    In the embodiment of FIG. 5, similar to that of FIG. 4, the heat exchange between the solar collector 1 and the air treatment unit 10 is carried out by direct injection of the air heated by the solar energy 26 in the rejection vein of the air handling unit 10.
    In summary, the present invention relates to an air treatment system, for cooling and heating the interior volume of a building, using an optimized combination between a thermal or hybrid solar collector, a thermodynamic system with mechanical compression and a system to desiccation, in order to ensure the regulation of the temperature inside a building in an economically, energetically and ecologically optimal way.
    It should be noted, moreover, that the invention is not limited to the embodiments described by way of examples and is capable of variants within the scope of the person skilled in the art.
