Description

Title of the invention: Planning and management of temperature and air in a building, and corresponding system

[0001] The technical field relates to methods and installations for managing temperature and air in buildings, in particular large private buildings (apartment buildings, large houses) or company buildings (factories, shops, shopping centers, logistics centers).

[0002] In the context of low-energy buildings, also known as active buildings, good temperature and air management is sought

[0003] A temperature of between 19 and 21° Celsius is usually expected in a building, so that users find the building comfortable.

[0004] Maintaining this temperature range may require, depending on outside temperatures, the use of heating systems in winter and cooling systems, particularly in summer. This requires the use of energy, which is costly.

[0005] It is known to insulate buildings effectively to limit the loss of heat or coolness, or calories or frigories, but this does not prevent the need to heat or cool the interior of said building according to variations in the external environment.

[0006] Since these buildings are of a large size, their heating or cooling requires a significant consumption of energy over time.

[0007] The same applies to the air used to ventilate such a building, which can be cold or hot depending on the outside environment; it is therefore necessary to temper it before injecting it into the building.

[0008] In addition, outdoor air can sometimes be polluted or contain allergens, such as pollen. During periods of high pollution or high allergen levels, it is necessary to install efficient and appropriate filtration systems to draw air from the building in order to renew the indoor air, which requires significant investment and maintenance.

[0009] In order to ensure adequate heating of areas of the building, it is known to equip a building with a computer system capable of managing the internal temperature of areas of said building according to the outside temperature.

[0010] This computer system can obtain information on the outside temperature, and take into account a number of parameters on said building to manage and control heating and cooling means so that said zones are in predetermined temperature ranges.

[0011] Information on the outside temperature can be obtained in a known manner by means of temperature measurement such as a thermometer placed outside the building, or by means of communication from external computer servers that record real-time temperatures from various locations near the building. These servers could, for example, belong to an organization or company capable of providing weather measurement and forecasting services, such as Météo France.

[0012] It is also known that said computer system capable of managing the internal temperature of areas of said building according to the outside temperature manages and controls heating and cooling means so that said areas are in predetermined temperature ranges at the required time.

[0013] Thus, in order for an office building to be at the desired temperature when employees return on Monday morning, the computer system can anticipate the time of heating or cooling according to the outside temperature, so that the office is within predetermined temperature ranges when employees of said office take up their posts.

[0014] Heating and / or cooling managed and controlled by the computer system requires a significant amount of energy, and in view of energy supply problems and the scarcity of fossil energy sources, it is essential to optimize energy consumption, and at the same time ensure a comfortable building for those who live, pass through or work in it.

[0015] One objective of the invention is to propose a method for managing and controlling the heating and / or cooling means of a building according to the external environment in a more optimized way.

[0016] Another objective of the invention is to propose a method to also optimize the supply of outside air into the building in order to reduce or even eliminate the aforementioned disadvantages.

[0017] Another objective of the invention is to provide an installation enabling the implementation of this process.

[0018] To this end, the invention relates to a method for planning and managing the heating and / or cooling of a building, suitable for implementation in a building comprising different zones, including so-called usage zones and so-called buffer zones, said method comprising: - a planning stage using a computer system to manage the accumulation of heat and / or cold in the buffer zones of a building, based on current and future weather information external to the building, - a temperature management step in the usage areas using a computer system that utilizes heat and / or cold accumulated in said buffer zones, based on current and future weather information near the building, to achieve and maintain a temperature in the building's usage areas within a predetermined temperature range.

[0019] In fact, this allows the building's temperature to be managed not only according to the current weather but also according to the weather forecast for the coming days or weeks, thus optimizing energy consumption to maintain the building, and especially the occupancy areas, at a comfortable temperature. By adjusting the temperatures by a few degrees or half-degrees higher or lower in the occupancy areas and buffer zones, it is possible to accumulate heat and / or cold in the buffer zones for later use in heating or cooling the occupancy areas, thereby saving energy without any significant impact on the comfort of people in the occupancy areas.

[0020] Usage areas can be those where people work, pass through, or reside. These usage areas can also change according to usage schedules. Usage areas can include offices, waiting rooms, sales areas, perishable goods warehouses, bedrooms, etc.

[0021] Buffer zones can be parking lots, warehouses, crawl spaces, corridors, storage areas, halls, large building sections, etc...

[0022] Buffer zones may correspond to areas of use outside of the times of use of said zones.

[0023] Consequently, temperatures in buffer zones can vary within a predefined temperature range that is wider than the predetermined temperature range of the usage zones. For this purpose, buffer zones can be areas where users never reside, or only for short periods and / or on brief occasions. Thus, the temperature in these buffer zones does not negatively impact user comfort.

[0024] According to a secondary feature of the process, the planning and management steps of this process may include steps of acquiring and recording meteorological information from previous periods measured near the building, in order to take them into account during planning and management by the computer system.

[0025] This allows us to be informed of the weather usually recorded near the building in previous years and to adjust the heating and cooling planning of the building accordingly.

[0026] According to another secondary feature of the process, the planning and management steps of this process may include steps for acquiring and recording planning and management information from previous periods as well as corresponding temperature measurement values ​​recorded in the areas of use, in order to take them into account during planning and management by the computer system.

[0027] This makes it possible to correct in the planning and management of this process the errors or choices made in previous planning.

[0028] According to another secondary feature of the process, this process further comprises: - a planning stage using a computer system for the accumulation, filtration, and heating and / or cooling of indoor air in the building's buffer zones, to achieve and maintain real-time and future air quality and / or temperature, particularly in usage areas, - a step of managing the quality and temperature of the air in the areas of use by a computer system using air accumulated in the buffer zones.

[0029] In fact, the comfort felt in a building depends on the temperature of said building, but also on the quality and temperature of the air that is injected into it.

[0030] The term air quality includes in particular the quantity of pollutants and / or pollen or microorganisms present in the air, as well as the presence or absence of odorous elements, and the humidity level of this air.

[0031] Air drawn in from outside the building can be treated by means of filtration, means of managing air humidity, means of detecting and measuring volatile substances, pollen or pollutants present in the air drawn into the building.

[0032] Building management is thus optimized by predicting the quality and temperature of the air in the areas of use and buffer zones according to external conditions, the air already stored, and the costs or availability of energy to filter, heat or cool the air.

[0033] According to another secondary feature of the process, the planning and management steps of this process may include steps of acquiring and recording measurements and observations of the quality and / or temperature of the outside air from previous periods near the building, in order to take them into account during planning and management by the computer system.

[0034] This allows us to be informed of the characteristics of the air usually recorded near the building in previous years and to adjust accordingly the planning of the filtration, heating and / or cooling of the air injected into the building.

[0035] According to another secondary feature of the process, the planning and management steps of this process may include steps for acquiring and recording planning and air management information from previous periods as well as measurement values ​​of temperature and air quality. weights recorded in the areas of use, in order to take them into account during planning and management by the computer system.

[0036] This allows the errors or choices made in previous planning and management of air filtration, heating and / or cooling to be included in the planning and management of this process.

[0037] The invention also relates to a computer system configured to process calculation algorithms for the management and control of heating and / or cooling in a building comprising different zones, including so-called usage zones and so-called buffer zones, said system comprising - means of planning the accumulation of heat and / or cold in the buffer zones of a building, based on current and future weather information external to the building, - means of temperature management in the areas of use by a computer system using the heat and / or cold accumulated in said buffer zones, based on current and future meteorological information near the building, to reach and maintain a temperature in the areas of use of the building within a predetermined temperature range.

[0038] According to a secondary feature of this computer system, it further comprises: - means of planning the accumulation, filtration and heating and / or cooling of indoor air in the building's buffer zones, to achieve and maintain real-time and future air quality and / or temperature, particularly in usage areas, - means of managing air quality and / or temperature in usage areas using air accumulated in buffer zones.

[0039] According to a secondary feature of this computer system, it includes calculation assistance software, capable of modifying its programming and algorithms to take into account the information recorded and received and improve the planning performance of the accumulation, filtration and heating and / or cooling of indoor air in the buffer zones of the building, and the performance of managing air quality and / or temperature in the usage zones.

[0040] According to a secondary feature of this computer system, it includes calculation assistance software, capable of modifying its programming and algorithms to take into account the information recorded and received and improve the performance of a planning and management process for the heating and / or cooling of a building.

[0041] Other objects and advantages of the present invention will become apparent from the following description, which refers to the accompanying single figure illustrating an example of implementation and in which:

[0042] [Fig. 1] is a schematic view of a building comprising an installation implementing a computer system according to the invention.

[0043] The invention relates to a method for planning and managing the heating and / or cooling of a building 1.

[0044] This process is suitable for implementation in a building 1 comprising different zones, including so-called ZU use zones and so-called ZT buffer zones.

[0045] This process comprises:

[0046] - a planning step using a computer system for the accumulation of heat and / or cold in the buffer zones ZT of building 1, depending on current and future weather information outside building 1.

[0047] - a temperature management step in the ZU usage zones by a system computer systems using heat and / or cold accumulated in said buffer zones ZT, based on current and future weather information near building 1, to achieve and maintain a temperature in the use zones ZU of building 1 within a predetermined temperature range.

[0048] The computer planning system and the computer temperature management system can be confused, as shown here. The computer system is described later.

[0049] The predetermined temperature range in the ZU usage zones can, for example, be between 19 and 21 degrees Celsius.

[0050] A predefined temperature range in the buffer zones ZT can, for example, be between 15 and 25 degrees Celsius.

[0051] The planning and management steps of this process may include steps for measuring and recording a quantity of heat and / or cold stored in the buffer zones ZT.

[0052] This allows for more efficient management of the use of accumulated heat and / or cold according to a temperature to be reached in the usage zones ZU and according to possible future accumulations in the buffer zones ZT, depending on current and future weather conditions near the building.

[0053] The planning and management steps of this process may include steps for acquiring and recording the costs or availability of current or future energy suitable for heating or cooling building 1, in order to take them into account during planning and management by the computer system.

[0054] This allows for the optimization of the energy consumption required to heat and / or cool building 1.

[0055] Thus, on a sunny day, photovoltaic power generation units 10 can provide inexpensive heat or cold production. It is then possible to accumulate heat or cold for the night for example, or to anticipate cloudy days.

[0056] The same reasoning can be applied, for example, in the case of wind power production units 11 during windy periods.

[0057] This method for planning and managing the accumulation and use of heat and / or cold may include: a) steps for current outdoor meteorological measurements and observations, as well as the acquisition and recording of future weather forecasts in the vicinity of building 1, b) steps for acquiring and recording information concerning real-time temperatures in different areas of the building, including usage zones (ZU) and buffer zones (ZT), b) steps for measuring and / or calculating the quantity of heat and / or cold required now and in the future to reach and maintain a predetermined temperature in building 1, particularly in the usage zones ZU, c) steps for measuring and / or calculating the quantity of heat and / or cold that can be accumulated or stored in the buffer zones ZT, in real time and in the future, d) steps for acquiring and recording information concerning predetermined temperature ranges in the usage zones ZU and predefined temperature ranges in the buffer zones ZT to be provided in the building.

[0058] This allows the management of building 1 to be optimized by forecasting temperatures in the usage zones ZU and buffer zones ZT according to external conditions, the heat and / or cold already stored, and the costs or availability of energy to heat or cool building 1 currently and in the future.

[0059] The planning and management steps of this process may include steps of acquiring and recording meteorological information from previous periods measured near building 1, in order to take them into account during planning and management by the computer system.

[0060] The planning and management steps of this process may also include steps of acquiring and recording planning and management information from previous periods as well as corresponding temperature measurement values ​​taken in the ZU usage areas, in order to take them into account during planning and management by the computer system.

[0061] In addition to the planning and management of the accumulation and use of heat and / or cold according to the invention, this method may further include: - a planning stage using a computer system identical or complementary to the previous one for accumulation, filtration and heating and / or cooling ventilation of indoor air in the buffer zones ZT of building 1, to achieve and maintain a current and future air quality and / or temperature, particularly in the usage zones ZU, - a step for managing air quality and temperature in the usage zones (ZU) by a computer system using air stored in the buffer zones (ZT).

[0062] It should be noted that the air supplied to building 1 can be heated or cooled by heating or cooling means respectively, or pass through buffer zones (ZT) to be heated or cooled. It can also be stored in said buffer zones (ZT).

[0063] The steps of the process relating to air planning and management may include: e) steps for measuring and observing the quality and / or temperature of the outside air in real time, as well as future forecasts in the vicinity of the building, f) steps for measuring and observing the quality and / or temperature of indoor air in real time, as well as future forecasts, (g) calculation steps for the filtration and / or heating or cooling efforts of outside air required in real time and in the future to achieve and maintain a predefined air quality and / or temperature to be injected into the building, particularly in ZU usage zones, h) steps for calculating the quantity of filtered and / or heated or cooled air that can be accumulated or stored in the buffer zones (ZT), both currently and in the future, i) steps for acquiring and recording information concerning predefined quality and / or temperature ranges for air quality and / or temperature in the use zones ZU and buffer zones ZT of building 1. j) steps for acquiring and recording information concerning building characteristics (inert, insulation, airtightness, etc.) and information from means of controlling the values ​​of these characteristics.

[0064] The planning and management steps of this process described above may include steps of acquiring and recording measurements and observations of the quality and / or temperature of the outside air from previous periods near building 1, in order to take them into account during planning and management by the computer system.

[0065] The planning and management steps of this process described above may also include steps of acquiring and recording planning and air management information from previous periods as well as corresponding temperature and air quality measurement values ​​taken in the ZU usage areas, in order to take them into account during planning and management by the computer system.

[0066] The invention also relates to a computer system, configured to process calculation algorithms for the management and control of heating and / or cooling of building 1 which includes usage zones ZU and buffer zones ZT.

[0067] This computer system comprises: - means of planning the accumulation of heat and / or cold in the buffer zones of a building, based on meteorological information external to the current and future building, in the form for example of a computer 2 comprising means of calculation, means of information acquisition and means of recording. - means of temperature management in the usage areas by a computer system using the heat and / or cold accumulated in said buffer zones ZT, based on current and future meteorological information near the building, to reach and maintain a temperature in the usage areas ZU of the building within a predetermined temperature range.

[0070] The means of acquiring information may include a human-machine interface and an interface between the computer 2 and peripheral units of the computer system allowing the reception of information.

[0071] The algorithms can be recorded in recording means which can be, for example, a computer memory of the hard drive type.

[0072] The control means may include contactors or remote controls of peripheral units of the computer system enabling their control.

[0073] The means of communication with peripheral units of the computer system may include a human-machine interface and an interface between the computer 2 and peripheral units of the computer system, as well as wired or wireless transmission means, allowing the sending and receiving of information.

[0074] It should be noted that the means of acquiring information and the means of communication can be confused.

[0075] The wired or wireless transmission means may include, for example, bundles of wires 3 connecting the computer 2 to the peripheral units of the computer system, or transmitting and receiving antennas 4.
