Description

INTEGRATED DEVICE, AND PREFABRICATED MODULAR CHA GE UFFA AND VENTILA TION OF A BUILDING OF LOCAL

The present invention relates to an integrated device for heating and prefabricated modular ventilation for a room with at least one wall in contact with outside air, and 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 increasing their glass surfaces, allowing for better working conditions while achieving energy savings (heating reduction, more efficient use of natural light).

Indeed, the quality of new materials used for glazing, such as glass HIT (high thermal insulation), now permit the construction of buildings whose facades are almost entirely glass, with minimal heat loss. Greater use of natural light reduces the power consumed by the interior lights. In addition, new thermal insulation materials used for walls and slabs of the building, increasing the efficiency of space heating by reducing heat loss.

Along with the use of these new materials, new emerging technologies, such as Active tiles, solar roofs or "Canadian wells" used for heating natural sources of heat and thermal regulation limiting the use expensive artificial heating systems (electric, hot water, steam).

For functional buildings like office buildings, schools, universities, hospitals or workshops, there are now inexpensive heating, light, economical and flexible well suited to this kind of buildings. These solutions use the inside against heart facades, ie 2

full front portions below the windows, to integrate or add y (systems "Tobler") of the heating panel casing by diffusing 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 effectiveness of these new technologies allow to reduce the consumption of heating, they necessitate an increased intake ventilation (air new and oxygen). Indeed, the presence of occupants and appliances clears stale air the need to renew by fresh air, or the quality of the sealing of these buildings no longer allows infiltration 'renewal of air (fresh air).

The damage caused by excess moisture in new buildings are rising, lack of adequate ventilation. The problem of fresh air ventilation is particularly crucial in office buildings or schools in which a significant number of occupants are present several hours in the same room. These may be subject to discomfort, headaches, and contagions are particularly fertile ground where the minimum of air hygiene quality standards are not met. This problem is now partially solved by ventilation systems that take air outside the building (fresh air) and distributes it in different rooms in the building or by opening windows causing the heat loss stored. The coexistence of a heating system and an air ventilation system in one building is expensive in terms of installation, maintenance and congestion. There are also air heating system that heats the fresh air ventilated, where it is necessary that the heated air is then humidified to be distributed in the rooms to be heated / ventilated. 3

Moreover, buildings achievements, particularly office buildings or schools, are subject to a new requirement of modularity (flexible space planning through mobile partitions) due to the evolution of the activities carried in these buildings. There is therefore a real need for a combined heating and ventilation system that is modular, compact, and which is inexpensive in terms of installation and operation.

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

The intake duct may further include a valve means controlling the passage of external air flow downstream of the outside air intake port. A communication may advantageously be provided between the intake and exhaust ducts, and be controlled by a valve device and disposed upstream of the heat exchanger.

The heat exchanger may comprise a valve device bypass controlling the opening and closing a bypass passage of the intake duct and / or a valve arrangement controlling the bypass opening and closing a bypass channel of the discharge duct.

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

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

upstream of the heat exchanger, while being thermally insulated relative to the inside of the discharge duct.

The device according to the invention may comprise a programmable control device controlling at least one of the following: the fan motors, the first source of additional heating, the respective valve means of the inlet conduit, the communication between the ducts inlet and outlet and the heat exchanger, the indoor temperature sensor, the presence detection device, the device for measuring the light in the room, the outside sunlight detection device, the device measuring the air quality in the room, the second source of additional heating, the power of the room light, blinds arranged inside or outside of one or more windows of the room.

The device of the invention may further comprise a prewired compartment can wherein as to fit a module comprising electrical outlets, telephone, information, television antenna and / or radio antenna, etc. ..

In a particularly advantageous embodiment, the device according to the invention may be attached to an outside pillar building retaining.

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 source of additional heating.

The 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 figure:. 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,

. 2 shows a vertical sectional view of a column of the integrated device for heating and ventilation of Figure 1, and 6

. 3 shows a horizontal sectional view along the axis AA 'of the device of Figures 1 and module 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 two windows separated by supporting pillars 3 of the building. In this application example of the present invention, for convenience reasons mentioned above, these windows cover the entire surface of the outer wall of the local î o 1. The integrated heating and ventilation device consists of a module

4 attached vertically along the pillars 3. Thus, a first advantage of the present invention is constituted by the fact that the heart against the partition is not monopolized by the heater, and the maximum glass surface can be operated .

15 Figure 2 shows a vertical sectional view of the module 4 of Figure 1.

As seen, in this particular embodiment, the module 4 is attached to a pillar 3 of the building support, between two windows 2. It is constituted by two ducts 5 and 6 which are preferably made by separating vertically module 4 into two parts by an insulating partition 7 thermally. The first

20 conduit 5 retrieves the air outside the building (fresh air or AN) via the outside air intake 15, to ventilate the inside the room 1 and the second conduit 6 retrieves 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 external noises are damped. The filter 8 may be common to the two ducts 5 and 6, or a specific folder can be added to the duct 6 in order to also protect the fan 1 1 and the heat exchanger 9 which will be described below. This or these filters can be advantageously consist of a cartridge filter (such as for example: "Camfil" or "Luwa") can be replaced or 7

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

A first source of fresh air the heater is constituted by a heat exchanger 9, for example of the plate heat exchanger type and disposed downstream of the filter 8 to enable heat exchange between the conduits of fresh air (fresh ) 5 and exhaust air (hot air) 6.

Preferably, lower portions (downstream) of each of the conduits 5 and 6 are arranged fans 10 and 11, controlled by respective motors 12 and 13. The two motors 12 and 13 may advantageously be disposed in the air duct nine 5, to be used as a second source of heating fresh air, and the engine 13 is well protected from the stale air that could clog faster than new.

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

The ducts 5 and 6 communicate with outside air into their high parts to the conduit 5, and low for the line 6 via intake and exhaust ports advantageously consist of a plurality of small diameter tubes 15 and 16 embedded in the concrete of the pillar 3. Their ends opening to the outside may be provided with baffles in order to guide the flow of air in the desired directions and to protect the apparatus against weather.

The operation of the heating and ventilation according to the present embodiment of the invention, and its advantages, are described below.

The fresh air outside is sucked via the inlet channels 15 in the upper part of the pipe 5, passes through the filter 8, absorbs heat from the exhaust air discharged through line 6, via the heat exchanger 9, and motors 12 and 13 and is diffused inside the room 1 at the bottom of the conduit 5. 8

Stale air from the room 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 evacuation channels 15 through the supporting pillar 3. as the exhaust air nine air intake and exhaust ports 15 and 16, the exhaust air outlets and air drawn from the local are the farthest possible to prevent a short circuit of airflow.

Thus, the temperature of outside air is controlled via the first inlet channels 15 of the pillar 3 and the walls in the upper part of the conduit 5 and fresh air is heated by the heat exchanger 9 to be reheated by heat recovery generated by the motors 12 and 13 and circulated in the lower part in the local 1. to facilitate the maintenance of the device according to the invention, the outer wall in contact with the local may be mounted on hinges to access the various components of the device.

The supply of fresh air heated and suction of stale air in the upper part of the duct 6, create an airflow that ensures a healthy air inside the room while maintaining thereof at a certain temperature, thanks to a compact device and without high power consumption. The device of the invention may further be provided with a humidifier device, but unlike air heating systems vented known, it can also do without, and thus limit the overall cost of the device again.

Thus, the installation of a complete device according to the invention requires to be operational, a power supply outlet, and two holes piercing through the exterior wall.

According to a first improvement of the present invention, a heating source and / or additional air can be disposed in the lower part of the conduit 5, downstream of the fan motors and the acoustic filter 14, to provide a heating power ( radiation shown by arrows q and / or by convection via line 5). When, for example, the power of 9 heating to provide the piece should be 120 to 200 Watts and that the motors 12 and 13 dissipate heat output of 30 Watt each (heat loss), this additional heat source must be able to providing at least one heating power of 60 to 140 Watts. This additional heating source may comprise an electric heater, a heat pump, a heater, or any other type of heating. Another source of heating / cooling can be constituted by a conventional air conditioning device or by a reversible heat pump.

In this embodiment, the conduits 5 and 6 communicate via an opening disposed through the wall 7, just below the contaminated air suction port of the duct 6, this opening being controlled by a valve 17. Similarly, a valve 18 controls the opening and closing of the pipe 5 immediately downstream of the fresh air intake 15 and the heat exchanger 9 is provided with a bypass valve 23 controlling the opening and closing a bypass channel (not shown) which allows the flow of fresh air to prevent the heat exchanger 9. These three valves 17, 18 and 23 are advantageously controlled by an electronic control device (not represent). The bypass valve 23 of the heat exchanger 9 can also be used to cool the inside of the room 1 by direct ventilation of fresh outside air, and the heat exchanger may include a second by-pass valve to deflected the exhaust air flow of the discharge duct 6.

According to a further improvement of the present invention, the device 4 can be a real automatic control system of the different parameters of a room, being provided with a programmable control circuit (not shown) integrated into the device, which controls the various sources of heating and cooling, the fan power and the valves mentioned above. For controlling the various organs, the device according to the invention may comprise various sensors transmitting to the control circuit based on signals which it controls the operation of the automatic device. 10

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

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

. a local temperature sensor 22 of conventional type, arranged for example, inside the duct 6 for the recovery of exhaust air, directly below the suction port,

. a sunlight sensor 24 of conventional type,

. a light detector (not shown) within the local (photometric probe) that can be integrated to the presence detector 21 and

. an air quality sensor (not shown) measuring the level of pollutants (CO2, vitiated gas, 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, to control thereof in based on presence information, temperature and / or sunlight from the sensors 21, 22 and / or 24.

Moreover, the programmable control circuit can advantageously control, by electrically connecting or infrared, the light switch 26 to open or close the lighting depending on the presence of occupants in the room, or selecting automatically the lighting power according to the detected brightness. In addition, the programmable control circuit may comprise a processor performing statistical calculations from memory input data, to the presence of occupants in the room, and modulate accordingly, for example, the holding times of the lighting based on time of day. These features enable new energy saving and are particularly well suited to the management of public and administrative buildings. For example, during a prolonged absence of the users or occupants (holidays) of the local, the device according to the invention, automatically or of 1 1

programming the last occupants, to prevent the internal local temperature drops below a minimum value of from 18 to 19 ° C. This provides greater 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" control and fully automatic temperature and air quality of a local provided with such an integrated device will now be described.

When the presence sensor transmits to the control device a signal indicating that the room has been emptied of its occupants, the latter after a certain period of renewal of the air in the room, (e.g., one hour) period which may be predetermined or modulated by, e.g., the air quality sensor, stops the fans 10 and 1 1 and closes the air intake valve new charges 18. in the absence of occupants, the renewed indoor air is of excellent quality, in particular its moisture content is kept constant and its temperature was lowered a few degrees to stabilize at for example 18 ° C.

Then, when the presence sensor indicates to the controller that a person enters the room, it controls the opening of valve 17, closing the valve 18, the cutoff Fan 1 1 and the engagement of the fan (and optionally, the opening of the bypass valve 23 of the heat exchanger 9), during a predetermined period of the order of one hour during which the air circuit is a closed circuit. This duration may advantageously be modulated by, e.g., measurements of the air quality sensor.

This allows, during this period, to recover the hot air very lightly loaded inside moisture, carbon dioxide and other nauseous gas to the ascent in the room temperature to 20 ° C. The new occupants arriving in a room where the air is excellent, it is not necessary that it be renewed immediately. 12

After this period of room temperature setting, when the temperature sensor detects the predetermined temperature value for the room, for example 20 ° C, the control device controls the various elements to make the device according to the invention functioning ventilation / heating as described above.

According to another refinement of the present invention, the apparatus 4 may be connected to a central heating system. Figure 3 shows a top sectional view along the broken line AA 'of the device 4 provided with this development. This improvement consists in placing in the device 4, at least one vertical heating line current over the entire height of the device 4. In the example of Figure 3, two vertical pipes 19 and 20 of this additional source of central heating, example hot water of 50 to 70 ° C, are disposed in the inner corners of the device 4, i.e. in the upper part of the duct 6 above the heat exchanger, and in the lower part of the conduit 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 may have any form suitable for the application that is made of the device according to the invention. It is also noteworthy that, in the upper part of the device 4, the pipes 19 and 20 are insulated vis-à-vis the inside of the exhaust duct from the exhaust air 6, but may radiate heat towards inside the room. In the lower part of the device 4, lines 19 and 20 radiate heat (shown by arrows q 2 in Figure 3) in the conduit 5 and directly inward of the local 1. The heat from this source additional heat is distributed directly towards the inside of the room by radiation through the wall of the column 4, and convection via the fresh air flow in the conduit 5. the insulation value chosen by material disposed between the conduits 19 and 20 and the wall 1 3

module 4, makes it possible to distribute the heat by radiation and by convection. in a particular desired ratio.

Advantageously, the heating pipes 19 and 20 are both provided in the lower part of the pipe 5 with fins for radiating more heat in the lower part of the device, or may supply a radiator in this location (e.g., type tubes fin), radiator which can be closed and opened by the user according to his requirements by means of a thermostatic valve, or automatically by means of a motorized valve on command from the control circuit according to preprogrammed criteria. This improvement is particularly suitable in the case of a renovation of a building in which a central heating system already exists, because it can replace existing expensive 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, for example, the modular installation of electrical outlets, telephones, computer equipment, antenna (radio / TN). The device may be provided in front of a prewired compartment which can come fit a support having these taken, depending on the needs of the premises where the device is installed according to the invention.

A number of integrated devices for heating and ventilation of different premises of a building can be coupled together as part of a heating and ventilation system of a building, in particular through the inner pipes 19 and 20 of a central heating.

The integrated device according to the invention is described based on Figures 1, 2 and 3, in the context of a particular application for ventilation and heating of a room in which the fronts are constituted of carriers and fully glazed pillars, but it can also be applied horizontally, vertically or in any other position. 14

under glass, in the amounts of these in the against-core, against exterior walls or ventilation ducts.

The interior spaces of the building that are not in contact with the sides of the building (corridors, stairs) and which do not require an atmosphere as pure as the premises in which are arranged devices according to the invention may also serve as ducts evacuation of stale air. As for example shown in Figure 2. apertures 25 may be arranged at the bottom of the interior partitions, or the bottom cabinets 26 for discharging the room air to the building and heat thereto. These openings 25 are optional for the ventilation of the room 1, since a perfectly hermetic room and comprising an integrated device according to the invention is ventilated and heated independently.

Finally, the peripheral area of ​​homogeneous and regular distribution of heat generated inside the building facades are a great barrier to heat loss from the building to the outside.

The device of the invention is compatible with all quality standards of Swiss and European air and so meets all the requirements to maintain independently, individually and automatically, a healthy atmosphere (in terms of temperature, humidity and purity of the ambient air) in each room in which is installed a device. In addition, the device of the invention allows to modulate individually and automatically, the atmosphere of each of the premises of a building, suited to each specific local requirements (type of activity, intermittent presence, etc.) thanks to its self-learning system. The device of the invention allows a significant savings of heating consumption (gas, electricity), electricity for lighting, space and maintenance. In addition, its modular structure is particularly suited to the construction of some buildings flexibility requirements, and its special structure allows the complete and modular prefabrication of such devices, and May 1

cost savings of manufacturing and installation that induces prefabrication. Finally, the techniques used for the production and use of these devices are simple, known, reliable and inexpensive.

The heating and ventilation system can be used in all types of residential buildings, and is particularly suitable for heating and ventilation of administrative buildings, schools, hospitals, and other buildings in which the premises are occupied permanent and / or intermittently, and likely to flexible arrangements.
