Description

INTEGRATED, PREFABRICATED AND MODULAR DEVICE FOR HEATING AND VENTILATING A BUILDING PREMISES

The present invention relates to an integrated prefabricated and modular heating and ventilation device, for a room comprising at least one partition in contact with the outside air, as well as to a heating and ventilation system of a building comprising such devices. .

In building construction, the trend is to increase the thermal insulation of buildings and the increase in their glass surfaces, which allows better working conditions while achieving energy savings (reduction of heating, more efficient use of natural light).

Indeed, the quality of the new materials used for glazing, such as HIT glazing (high thermal insulation), today make it possible to produce buildings whose facades are almost entirely glazed, with minimal heat losses. Greater use of natural light reduces the power consumed by interior lighting. In addition, new thermal insulation materials used for partitions and building slabs, increase the efficiency of space heating by reducing heat loss.

In addition to the use of these new materials, new emerging technologies, such as active slabs, solar roofs or "Canadian wells", use natural sources of heat and thermal regulation for heating by limiting their use expensive artificial heating systems (electric, hot water, steam).

For functional buildings such as administrative buildings, schools, universities, hospitals or workshops, there are currently inexpensive, light, economical and modular heating systems well suited to this type of building. These solutions use the inner heart against facades, that is to say the 2

solid facade parts under windows, to integrate or add ("Tobler" systems) heating boxes by panel diffusing the heat by radiation and convection. These boxes are also used for passing the power distribution cables, telephone connections and lines ^of computers.

However, if the quality of these new materials in terms of thermal insulation and sealing, and the efficiency of these new technologies, make it possible to reduce heating consumption, these make it necessary to provide more ventilation (air new and oxygen). Indeed, the presence of occupants and devices gives off stale air that needs to be renewed with fresh air, but the quality of the waterproofing of these buildings no longer allows infiltration of the air. renewal air (fresh air).

The damage caused by excess humidity in new buildings is increasing due to the lack of adequate ventilation. The problem of fresh air ventilation is particularly crucial in administrative buildings or schools, where a large number of occupants are present for several hours in the same room. These can be prone to discomfort, headaches, and contagions find particularly fertile ground when minimum air quality standards are not met. This problem is currently partially solved by ventilation systems which take air outside the building (fresh air) and distribute it in the different rooms of the building or by opening the windows causing heat loss. stored. The coexistence of a heating system and an air ventilation system in the same building is costly in terms of installation, maintenance and space. There are also air heating systems which heat fresh ventilated air, in which it is necessary that the heated air is then humidified in order to be distributed in the rooms to be heated / ventilated. 3

In addition, the construction of buildings, in particular office or school buildings, is subject to a new requirement of modularity (flexibility of the layout of the premises thanks to movable partitions) due to the evolution of the activities carried out in these buildings. There is therefore a real need for a system combining heating and ventilation, which is modular, compact, and which is inexpensive in terms of installation and operation.

The present invention provides an integrated, prefabricated and modular device for ventilation and heating, which meets these requirements and which solves the problems of the known systems mentioned above.

Indeed, the present invention relates to an integrated heating and ventilation device of the type mentioned above, which is characterized in that it comprises: an outside air intake duct comprising an outside air intake orifice at the through said partition, a heat exchanger, and, downstream, a fan powered by a motor, said intake duct opening into an air diffusion opening in the room; and an interior air exhaust duct comprising an interior air intake orifice, said heat exchanger with said intake duct, and, downstream, a fan powered by a motor, said exhaust duct opening in an interior air discharge opening through said partition.

In a first embodiment of the present invention, at least one of said fan motors is arranged in said intake duct downstream of said heat exchanger, to be used as a source of heating the outside air.

This device may further include an air filter disposed in the intake duct and / or in the exhaust duct, upstream of the heat exchanger as well as an acoustic filter upstream and / or downstream of the engines. fans. 4

The internal air evacuation orifice and / or said external air intake orifice can advantageously consist of a plurality of channels of small dimensions passing through said partition.

The intake duct may include a first additional heating source between the heat exchanger and the diffusion opening, consisting for example of an electric heater, a heat pump, a radiator, or any other type of heating.

The intake duct may also include a valve device controlling the passage of the outside air flow downstream of the outside air intake orifice. Communication can advantageously be provided between the intake and exhaust ducts, and be controlled by a valve device and arranged upstream of the heat exchanger.

The heat exchanger may include a by-pass valve device controlling the opening and closing of a deflection channel of the intake duct, and / or a by-pass valve device controlling the opening and closing of a deflection channel of the exhaust duct.

The device according to the invention can advantageously comprise at least one component from the following components: a sensor for the interior temperature of the room, a device for detecting presence in the room, a device for measuring the light in the room, a device for detection of outdoor sunlight, and a device for measuring the air quality of the room.

The device according to the invention can advantageously include a second additional central heating source, consisting of one or more pipes arranged inside the inlet and outlet pipes. These so-called pipes can be fitted with fins in the lower part of the intake pipe. They are preferably arranged against the wall of the intake and exhaust ducts which are in contact with the interior of the room. They can run along the intake duct downstream of the heat exchanger and along the exhaust duct in 5

upstream of the heat exchanger, while being thermally insulated from the interior of the exhaust duct.

The device according to the invention may include a programmable control device controlling at least one of the following elements: the fans motors, the first additional heating source, the respective valve devices of the intake duct, of the communication between the ducts intake and exhaust system and the heat exchanger, the indoor temperature sensor, the presence detection device, the room light measurement device, the outdoor sunshine detection device, the device measuring the air quality of the room, the second additional heating source, the power of the room lighting, blinds arranged inside or outside of one or more windows of the room.

The device according to the invention can also include a prewired compartment in which a module can be fitted, comprising electrical, telephone, information, television antenna and / or radio antenna, etc. ..

In a particularly advantageous embodiment, the device according to the invention can be fixed to an external pillar for supporting the building.

The present invention also relates to a heating and ventilation system of a building comprising at least two devices as described above, coupled by their second additional heating source.

The present invention will be better understood, and additional technical characteristics and advantages will appear on reading the description of an embodiment and its improvements, illustrated by the following figures:. 1 shows the facade of a building to the interior of a premises equipped ^with an integrated device for heating and ventilation according to a first embodiment of the invention,

. FIG. 2 represents a view in vertical section of a column of the integrated heating and ventilation device of FIG. 1, and 6

. 3 shows a horizontal sectional view along the axis AA 'of the module of the device of Figures 1 and 2 according to an improvement of the present invention.

5 Figure 1 shows a front view ^of a building seen from the inside ^of a local

1. This facade consists of bay windows 2 separated by support pillars 3 of the building. In this example of application of the present invention, for reasons of convenience mentioned above, these bay windows cover the entire surface of the external partition of the room 1. î o The integrated heating and ventilation device consists of a module

4 fixed vertically along the pillars 3. Thus, a first advantage of the present invention consists in the fact that the heart of the partition is no longer monopolized by the heating device, and the maximum glazed surface can be exploited .

FIG. 2 represents a view in vertical section of the module 4 of FIG. 1.

As we have seen, in this particular embodiment, the module 4 is attached to a pillar 3 for supporting the building, between two bay windows 2. It consists of two conduits 5 and 6 which are preferably made by separating vertically the module 4 in two parts by a thermally insulating partition 7. The first

20 duct 5 collects air outside the building (fresh air, or AN) via outside air intakes 15, to ventilate it inside room 1, and the second duct 6 collects indoor air (contaminated air, or AN) for discharging to ^the outside via the exhaust ports 16.

The duct 5 comprises in its upper part, a filter 8 through which ^air

25 outside is filtered and outside noise is dampened. This filter 8 can be common to the two conduits 5 and 6, or a specific filter can be added to the conduit 6, in order also to protect the fan 11 and the heat exchanger 9 which will be described below. This or these filters may advantageously consist of a cartridge filter (of the type for example: "Camfil" or "Luwa") which can be replaced or 7

easily cleaned. For this, the interior facade of the device according to the invention is advantageously mounted on hinges (not shown).

A first source for heating the fresh air is constituted by a heat exchanger 9, for example of the plate heat exchanger type, and arranged downstream of the filter 8 to allow the exchange of heat between the fresh air ducts (fresh ) 5 and stale air (hot air) 6.

Preferably, in the lower parts (downstream) of each of the conduits 5 and 6, fans 10 and 11 are arranged, controlled by respective motors 12 and 13. The two motors 12 and 13 can advantageously be arranged in the air duct new 5, in order to be used as a second source of heating of the fresh air, and the engine 13 is thus protected from the stale air which could foul it more quickly than the fresh air.

On the other hand, the duct 5 can advantageously include in its lower part (downstream), an acoustic filter 14 the purpose of which is to constitute a second filter to external noise, as well as to the noises of the fan 10 and of the motors 12 and 13 .

The ducts 5 and 6 communicate with the outside air in their upper parts for the duct 5, and low for the duct 6, via inlet and outlet openings advantageously made up of a plurality of small diameter tubes 15 and 16 embedded in the concrete of pillar 3. Their ends opening onto the outside can be fitted with deflectors in order to be able to orient the air flows in the desired directions and to protect the device against bad weather.

The operation of the heating and ventilation device according to this embodiment of the invention, as well as its advantages, will now be described.

The fresh air from the outside is sucked in via the intake channels 15 in the upper part of the duct 5, passes through the filter 8, absorbs heat from the stale air evacuated by the duct 6, via the heat exchanger 9, and motors 12 and 13. then is diffused inside the room 1 in the lower part of the duct 5. 8

The local exhaust air is recovered from the top portion of the duct 6, passes through the filter 8 and gives up heat to the fresh air through the heat exchanger 9, to then be discharged ^outside in its part low via the exhaust channels 15 through the support pillar 3. As well as the fresh air intake and exhaust air openings 15 and 16, the exhaust air and air intakes drawn from the premises are as far apart as possible, in order to avoid a short circuit in the air flows.

Thus, the outside air temperature is first regulated via the inlet channels 15 of the pillar 3 and the walls in the upper part of the duct 5, then the fresh air is heated by the heat exchanger 9 to be again heated by the recovery of heat released by the motors 12 and 13, and distributed in the lower part in the room 1. To facilitate maintenance of the device according to the invention, the outer wall in contact with the room can be mounted on hinges in order to have access to the various components of the device.

The supply of heated fresh air and the suction of stale air in the upper part of the duct 6, create an air flow which ensures good air hygiene inside the room while maintaining it at a certain temperature, thanks to a space-saving device and without high energy consumption. The device according to the invention can also be provided with a humidifier device, but, unlike known systems for heating ventilated air, it can also do without it, and thus again limit the overall cost of the device.

Thus, the installation of a complete device according to the invention requires, in order to be operational, only a current supply socket, and two orifices to be drilled in the exterior wall.

According to a first improvement of the present invention, an additional heating and / or air conditioning source can be arranged in the lower part of the duct 5, downstream of the fan motors and the acoustic filter 14, in order to provide heating power (by radiation represented by arrows q and / or by convection via conduit 5). When, for example, the power of 9 heating to provide to the room must be 120 to 200 Watts and that the motors 12 and 13 dissipate a thermal power of 30 Watts each (heat losses), this additional heating source must be able to provide at least a heating power of 60 to 140 Watts. This additional heating source can consist of electric heating, a heat pump, a radiator, or any other type of heating. Another source of heating / air conditioning can be a conventional air conditioning device or a reversible heat pump.

In the present embodiment, the conduits 5 and 6 communicate by an opening arranged through the wall 7, just below the stale air suction orifice of the conduit 6, this opening being controlled by a valve. 17. Similarly, a valve 18 controls the opening and closing of the duct 5 just downstream of its fresh air intake 15, and the heat exchanger 9 is provided with a bypass valve 23 controlling the opening and closing a deflection channel (not shown) which allows the flow of fresh air to avoid the heat exchanger 9. These three valves 17, 18 and 23 are advantageously controlled by an electronic control device (not represented). The bypass valve 23 of the heat exchanger 9 can also be used to cool the interior of the room 1 by direct ventilation of fresh outside air, and the heat exchanger can include a second bypass valve in order to deflected the stale air flow from the exhaust duct 6.

According to a new improvement of the present invention, the device 4 can constitute a real automatic regulation system for the different parameters of a room, by being provided with a programmable control circuit (not shown) integrated into the device, which controls the different sources of heating and air conditioning, power supply to the fans and the valves mentioned above. To control these different organs, the device according to the invention may include different sensors transmitting signals to the control circuit on the basis of which it automatically controls the operation of the device. 10

Thus, in the particular embodiment of the invention, the device 4 can be provided with the following components:

. a presence detector 21, for example of the PIR ECO-IR 180A / 360A type disposed on the outside of the device wall in contact with the inside of the room,

. a room temperature sensor 22 of conventional type, arranged for example, inside the duct 6 for recovering stale air, just below its suction orifice,

. a sunshine sensor 24 of conventional type,

. a light detector (not shown) inside the room (photometric probe) which can be integrated into the presence detector 21, and

. an air quality sensor (not shown) measuring the pollutant levels (CO2, stale gases, etc.).

Advantageously, the control circuit of the device according to the invention can be connected to a device for opening and closing blinds (not shown) located outside or inside the windows, in order to control them by function of the presence, temperature and / or sunshine information transmitted by the sensors 21, 22 and / or 24.

In addition, the programmable control circuit can advantageously control, by electrical or infrared connection, the light switch 26. in order to open or close the light according to the presence of occupants in the room, or to automatically choose the lighting power according to the detected brightness. In addition, the programmable control circuit may include a processor performing statistical calculations from data entered in memory, on the presence of occupants in the room, and modulate accordingly, for example, the durations of maintenance of the lighting according to the time of day. These characteristics allow new energy savings and are particularly well suited to the management of public and administrative buildings. For example, during a prolonged absence of users or occupants (vacations) of the premises, the device according to the invention allows, automatically or on 1 1

programming by the last occupants, to prevent the interior temperature of the room from falling below a minimum value of 18 to 19 ° C. This provides better comfort for the rise in temperature when the room is used again, and prevents premature aging of the building (or room).

An example of "intelligent" and fully automatic regulation of the temperature and air quality of a room provided with such an integrated device will now be described.

When the presence detector transmits a signal to the control device indicating that the room has been emptied of its occupants, the latter, after a certain period of air renewal in the room, (for example, one hour), period which can be predetermined or modulated by, for example, the air quality sensor, stops the fans 10 and 1 1 and closes the fresh air inlet valve 18. In the absence of occupants, the renewed indoor air is of excellent quality, in particular its humidity is kept constant, and its temperature has dropped by a few degrees to stabilize at, for example, 18 ° C.

Then, when the presence detector indicates to the control device that a person enters the room, it controls the opening of the valve 17, the closure of the valve 18, the shutdown of the fan 1 1 and the switching on of the fan. (and possibly, the opening of the bypass valve 23 of the exchanger 9), for a predetermined period of the order of one hour during which the air circuit operates in a closed circuit. This duration can advantageously be modulated by, for example, the measurements of the air quality sensor.

This allows, during this period, to recover the hot indoor air very low in humidity, carbon dioxide and other nauseous gases, for the rise in temperature of the room to 20 ° C. New occupants arriving in a room where the air is of excellent quality, it does not need to be renewed immediately. 12

After this period of warming up the room, when the temperature detector registers the value of the predetermined temperature for the room, for example 20 ° C., the control device controls the various elements to return the device according to the invention to its operation. ventilation / heating as described above.

According to another improvement of the present invention, the device 4 can be connected to a central heating network. Figure 3 shows a sectional view from above along the broken axis AA 'of the device 4 provided with this improvement. This improvement consists in having in the device 4, at least one vertical heating pipe running over the entire height of the device 4. In the example of FIG. 3, two vertical pipes 19 and 20 of this additional central heating source, by example with hot water from 50 to 70 ° C, are arranged in the interior corners of the device 4, that is to say in the upper part of the duct 6 above the heat exchanger, and in the lower part of the duct 5 below the heat exchanger. In the present embodiment, the module 4 has a rectangular or square section, but it is obvious that this section can have any shape suitable for the application which is made of the device according to the invention. It should also be noted that, in the upper part of the device 4, the pipes 19 and 20 are insulated from the inside of the exhaust air exhaust pipe 6, but can radiate heat towards inside the room. In the lower part of the device 4, the pipes 19 and 20 radiate heat (represented by the arrows q ₂ in FIG. 3) in the pipe 5 and directly towards the interior of the room 1. The heat from this source of additional heat is thus diffused directly towards the interior of the room by radiation through the wall of the column 4, and by convection via the flow of fresh air circulating in the duct 5. The degree of insulation chosen from a material disposed between pipes 19 and 20 and the wall 1 3

module 4, distributes heat by radiation and convection. in a particular desired report.

Advantageously, the heating pipes 19 and 20 are both provided in the lower part of the duct 5 with fins in order to radiate more heat in the lower part of the device, or can supply a radiator at this location (for example, of the tube type with fins), radiator which can be closed and opened by the user according to his needs by means of a thermostatic valve, or automatically by means of a motorized valve on command of the control circuit according to preprogrammed criteria. This improvement is particularly well suited in the case of a renovation of a building in which a central heating network already exists, since it can replace the costly existing bulky radiators. These conduits 19 and 20 can be mounted on the inner face of the wall mounted on hinges, and are, in this case connected to the central heating network by flexible conduits.

Many other improvements can be envisaged, such as, for example, the modular installation of sockets, telephones, computer equipment, antenna (radio / TN). The device can be provided on the front with a pre-wired compartment on which can be fitted a support comprising these different sockets, according to the needs of the room where the device according to the invention is installed.

A number of integrated devices for heating and ventilating the various rooms of the same building can be coupled together as part of a building heating and ventilation system, in particular via the internal pipes 19 and 20 d '' central heating.

The integrated device according to the invention is described from FIGS. 1, 2 and 3, in the context of a particular application for the ventilation and heating of a room whose facades consist of load-bearing pillars and entirely glazed, but it can also be applied horizontally, vertically or in any other position. 14

under glass, in the uprights thereof, in cores, against exterior walls or ventilation ducts.

The interior spaces of the building which are not in contact with the facades of the building (corridors, stairs) and which do not require an atmosphere as pure as the rooms in which the devices according to the invention are arranged, can also serve as conduits for ^evacuation of stale air. As for example shown in FIG. 2. openings 25 can be arranged at the bottom of the interior partitions, or at the bottom of cupboards 26, to evacuate the air from the room towards the interior of the building and heat it. These openings 25 are optional for the ventilation of the room 1, insofar as a perfectly hermetic room and comprising an integrated device according to the invention is ventilated and heated independently.

Finally, the peripheral zone of homogeneous and regular distribution of the heat created inside the facades of the building constitutes an excellent obstacle to the heat losses from the interior of the building towards the outside.

The device according to the invention is compatible with all Swiss and European air quality standards, and thus meets all the requirements required to maintain autonomously, individually and automatically, a healthy atmosphere (in terms of temperature, humidity and ambient air purity) in each room in which such a device is installed. In addition, the device according to the invention makes it possible to individually and automatically modulate the atmosphere of each of the premises of a building, adapted to the requirements specific to each of the premises (type of activity, intermittent presence, etc.). , thanks to its self-learning system. The device according to the invention allows significant savings in heating consumption (gas, electricity), electricity for lighting, space and maintenance. In addition, its modular structure is particularly well suited to the flexibility requirements of the layout of certain buildings, and its particular structure allows the complete and modular prefabrication of such devices, and the 1 5

savings in manufacturing and installation costs that this prefabrication induces. Finally, the techniques implemented for the production and use of these devices are simple, known, reliable and inexpensive.

The heating and ventilation device can be used in all types of residential buildings, and is particularly well suited for heating and ventilating the premises of administrative buildings, schools, hospitals, and other buildings in which the premises are occupied. permanently and / or intermittently, and subject to flexible arrangements.
