Description

[0001] The current invention involves a method for controlling a hybrid ventilation system for ventilative cooling of a building. The current invention also relates to a hybrid ventilation system comprising a hygienic ventilation system as a central ventilation system and a decentralized air supply device.

[0002] The current invention also involves a computer-implemented method, a data processing device, a computer program that contains instructions to have a hygienic ventilation system perform the steps of the aforementioned method and a computer-readable storage medium containing the computer program.State of the Art of Technology

[0003] Due to climate change, there are more and more periods of high temperatures, drought and much sun. This causes discomfort from overheating in residences. There is overheating of a residence if the interior temperature exceeds 25 degrees for a long period of time. This heat remains in the house for a long time and it is thus hard to keep the house cool. There is also an increasing need for cooling because houses are better insulated. No heat is lost in the winter, but no cold air can enter in the summer. Once a residence is warm, it is hard to bring the temperature down.

[0004] This is especially the case in apartments. There the heat also comes from neighbouring apartments, so sun shades can help, but are not effective enough to keep the temperature under control, so a solution must be found to remove the heat from an apartment.

[0005] It is difficult to cool these residences. If district heating is in use, active cooling solutions (such as air-water heat pumps) are difficult to use. Solutions with air-conditioners (e.g. air-air heat pumps) then have acoustic and sustainable energy sources as a challenge.

[0006] A passive alternative is naturally cooling with air through actively opening shutters (or windows), but because there are sometimes not two façades available and / or there is no skylight, natural flows are often limited, therefore big shutters are required or a limited cooling capacity is realized.

[0007] One variant of natural cooling without using energy, is to mechanically evacuate the heat from the residence. As a result, natural solutions for cooling and hygienic mechanical ventilation systems are installed next to each other and there is no synergy between these systems in one residence, with the risk of suboptimal air quality, reduced comfort and often reduced energy performance.

[0008] This problem is very acute especially in apartments due to the specific energy provision, smaller dimensions and the collective character of energy exchange with the neighbouring apartments. But it is a general problem that applies for any type of residence, above all when there is no natural air current coming through or cross ventilation or thermal air flow.Objective of the invention

[0009] The current invention and the preferred designs of it have the objective of offering a solution for one or more of the aforementioned disadvantages. One objective of the invention can therefore be to create a hybrid ventilation system that is also suitable for ventilative cooling of the same residence.

[0010] Another objective of the invention can therefore be to create a method for the control of a hybrid ventilation system that is suitable for ventilative cooling of a residence.

[0011] In particular, it can be an objective of the invention to create a hybrid ventilation system for hygienic ventilation and ventilative cooling of the same residence during summer nights. Preferably with a limited influence on the acoustic load, the price and the performance or use of the ventilation system.Description of the invention

[0012] This objective is achieved, according to the invention, with a method for ventilative cooling of a building that displays the technical characteristics of the first independent claims.

[0013] For this the current invention relates to a method for controlling a hybrid ventilation system and a decentralized air supply system for the supply of outside air via an opening in an outside façade of the building. The term "hygienic ventilation system" refers to the whole of various components that ensure that the air in rooms of the building is refreshed in a controlled manner.

[0014] In particular, the invention provides for a method for controlling a hybrid ventilation system comprising a hygienic ventilation system with an exhaust passage that extends between a main exhaust connection and at least one auxiliary exhaust connection and exhaust flow control units to ensure an air exhaust flow from the main exhaust connection via the exhaust flow passage to the main exhaust connection to at least one auxiliary exhaust connection. The term "connection" refers to an open end where an air passage may or may not be connected, such as an opening in the housing of the ventilation box or the end of an air passage. This type of hygienic ventilation system is described, for example, in NL 2014612 and NL 2022733, the content of which is included here for reference.

[0015] In a first aspect of the invention, which may occur in combination with the other aspects and embodiments of the invention described herein, the invention involves a method for producing this type of hybrid ventilation system involving a sensor for measuring a parameter related to the supply flow of outside air through the decentralized air supply installation. This method involves the step of controlling the exhaust flow control means based on a value measured by the sensor.

[0016] By controlling the exhaust flow control means based on a parameter related to the supply flow of outside air through the decentralized air supply installation, using a sensor, the air exhaust can effectively and efficiently be adjusted to the air supply through the decentralized air supply installation. In particular, this makes it possible for the hygienic ventilation system to ventilate and cool when the decentralized air supply installation is activated or opened. In addition, the exhaust flow can be set using the decentralized supply flow. In an alternative function, one part of the exhaust flow, meaning one or more of the zonal exhaust flows related to the auxiliary exhaust connections can be adjusted to the decentralized supply flow.

[0017] In one embodiment, which may occur in combination with the other aspects and embodiments of the invention described here involves an aforementioned method comprising the steps of: adjusting a ventilation mode of the hygienic ventilation system based on a value measured by sensors and the control of the exhaust flow control means based on one or more parameters related to the ventilation mode of the hygienic ventilation system. The adjustment of a ventilation mode of the hygienic ventilation system based on a value measured by the sensor can involve the following steps: the setting of a hygienic ventilation mode when the value measured by the sensor is related to a minimum flow rate of the decentralized air supply installation and the setting of a summer night ventilation mode when the value measured by the sensor is not related to the supply flow of the outside air that is different from the minimum supply flow of the decentralized air supply installation. Preferably, the minimum supply rate of the decentralized air supply installation is zero or negligible.

[0018] In one embodiment, which may occur in combination with the other aspects and embodiments of the invention described here, there is an aforementioned method, wherein the value measured by the sensor is one or more of the following parameters: the indoor temperature, the outdoor temperature, CO 2< , relative humidity and a position sensor.

In other words, in the summer night ventilation mode, more air than necessary will flow through at least one of the auxiliary exhaust connections to achieve the hygienic ventilation flow rates. The hygienic exhaust air flows will flow through the other auxiliary exhaust connections.

[0020] Preferably, the thermal flow is determined based on the value measured by the sensor. In particular, the thermal flow is consistent with the supply flow of the outdoor air through the decentralized air supply installation.

The method involving the step of ensuring the air exhaust flow from the main supply connection via the exhaust flow passage to create the exhaust air flow with the exhaust booster.

The decentralized air input system can passively allow air to flow in by using the influence of the pressure difference between the interior and exterior of the building to bring outside air into the building, or actively bring air in using mechanical ventilation. The decentralized air input system can be designed as an element that can be opened, such as a window, door, sliding door, grate or in particular a summer night ventilation shutter.

[0038] Fig. 1 shows a building 1a in the form of a residence consisting of multiple rooms 11, 12, 21, 22 and traffic area 30, such as a passageway, hallway or landing that provides access to the rooms. The of the building shown in figure 1 has multiple living spaces in the form of rooms 11, 12, such as a living room or a bedroom, into which the supply air SUP can be pumped in via the auxiliary supply (not shown). The building 1a also has functional spaces in the form of rooms 21, 22, for example a toilet room, a bathroom or a kitchen, from which the ETA exhaust air can be removed via the ancillary exhaust passages 4 ,5. Each of these auxiliary passages 4, 5 are connected to an auxiliary connection 123-125 of a hygienic ventilation system 100. With one or more distribution pieces (not shown), multiple similar auxiliary passages can be connected to one auxiliary connection. The building also has a main exhaust passage 8 for removing the exhaust air EHA from a main exhaust connection 122 of the hygienic ventilation system 100.

[0039] The building 1a also has a decentralized air supply system in the form of a summer night vent 200 for supply of outside air into one of the living spaces. A summer night vent is a vent that thanks to the supply of large ventilation airflows, ensures efficient cooling of the building according to the summer night ventilation principle. Typically, a summer night vent 200 has an anti-burglary, rain resistant and / or insect-proof outside grate that can be opened without any negative consequences. In particular, the summer night vent 200 is designed to be opened through an external signal or for manual opening, to send a signal which can be received by the hygienic ventilation system 100 or another connected ventilation system. In reaction to receiving the signal, the hygienic ventilation system 100 can create a thermal flow Q THERM by upping the flow Q ETA of the exhaust air ETA to increase the pressure difference over the summer night vent 200. Thus, the same cooling capacity can be achieved (with regard to natural ventilation) with more freedom in the location and dimensions of the summer night vent 200. For example, a summer night vent with a smaller surface and fewer summer night vents placed further apart will have the same air flow.

[0040] One embodiment of the hygienic ventilation system 100 is shown in figure 2. This hygienic ventilation system 100 has a housing shown by 101 with an air supply connection 122 to which the main supply passage 7 is to be connected. On the other end of the housing there are one or more, in the figure three, used ancillary exhaust connections 123-125 and optionally one or more, in the figure one, auxiliary cooling connection 160 with an auxiliary cooling vale 162 for connecting the auxiliary cooling connection 160. The exhaust plenum 120 extends between the auxiliary exhaust connections 123 and the exhaust air connection 122. The output of air takes place using the booster 121 that is placed in the exhaust plenum near the main exhaust connection 122.

[0041] In the basic design of the hygienic ventilation system 100, the air flows depending on the resistance out of the various passages without further options for adjustment toward the various rooms. In connection with offering the option for a desired distribution of the input air, hygienic flow regulator valves 126- 128 are placed in the auxiliary connections. Each flow regulator can be contained in a cassette that is inserted into a cassette chamber that is located at or behind the respective auxiliary supply connection. Each cassette can also have a measurement system that can contain a sensor, for example, for measuring the CO 2< value of the air, relative humidity and the like. Based on the measurements of this sensor, not only the hygienic ventilation system but also the summer night vent can be controlled.

[0042] Fig. 3 shows a building 1b in the form of an apartment building consisting of multiple residential units with rooms 11-13, 21-26 and traffic areas (not shown) such as a passageway, hallway or landing that provides access to the rooms. Each of the residential units shown in figure 3 has residential spaces in the form of rooms, such as a living room or a bedroom, into which the supply air SUP can be pumped in via the auxiliary supply passages 2. Exhaust air, ETA can also be removed through auxiliary exhaust passages 4 from the functional spaces 21-26 in the form of rooms, such as a toilet room, bathroom or kitchen. Each of these auxiliary passages 2, 4, 5 are connected to a hygienic ventilation system in the form of a hygienic ventilation assembly 300a-300c. With one or more distribution pieces (not shown), multiple similar auxiliary passages can be connected to one auxiliary connection. The building also contains a main inflow passage 6 for letting in outside air, ODA to a supply connection of a hygienic ventilation assembly 300a-300c and a main exhaust passage 7 to expel the exhaust air, EHA from a main exhaust connection of the hygienic ventilation assembly 300a-300c.

[0043] Each residential unit also has a decentralized air supply system in the form of a summer night vent 201-203 for supply of outside air into one of the spaces in the accommodation. In particular, the summer night vent 200 is designed to be opened through an external signal or for manual opening, to send a signal which can be received by the hygienic ventilation system or another connected control system. In reaction to receiving of the signal, the hygienic ventilation system can create a thermal flow Q THERM by increasing the exhaust Q ETA to increase the pressure difference over the summer night vent 200 so that a smaller vent can be used to achieve the same flow rate.

[0044] In the basic design of the hygienic ventilation assembly 300a-300c, the collectively created air flows through a central control valve 311, 312, 313; 321 and depending on the resistance in the various auxiliary passages 2, 4, 5 without further options for adjustment toward the various rooms, and the air is suctioned out. In connection with offering the option for a desired distribution of the input air, hygienic flow regulators (not shown) are placed in the auxiliary connections or auxiliary passages in zones 322-323 or locally 324-325. Each control valve can be enclosed in a cassette. Each cassette can also have a measurement system that can contain a sensor, for example, for measuring the CO2 value of the air, relative humidity, temperature and the like. Between the central, zonal or local control valve 311-313, 321-325 and a collective air passage 8, 9, there can be a constant volume regulator 310, 320 for limiting the maximum air flow through the auxiliary air passages. In addition, there can be a fire valve (not shown) between the constant volume regulator 310, 320 and the collective air passage 8, 9.

[0045] The function of the central hygienic ventilation system 100, 300a-300c is illustrated in figure 4. An internal or external control unit or processor 150 is set to control the exhaust booster 121 or the one or more exhaust regulation valves 320-325. The control of these elements is dependent on the ventilation mode of the hygienic ventilation system. As is clear in figure 4, which shows the time lapse of the air supply flow the air exhaust flow Q ETA in a hygienic ventilation mode I (left) and a summer night ventilation mode II (right).

[0046] In the hygienic ventilation mode, the hygienic ventilation system functions like a conventional demand-driven ventilation system and the ventilation requirement is adjusted to the air quality between a minimum, set ventilation flow Q SET , MIN and a maximum, set ventilation flow Q SET , MAX . The set ventilation flows Q SET are determined based on the legal ventilation standards. The demand-driven ventilation flow Q HYG can be controlled based on CO 2< , humidity, time (day and night as 2-zone system) and any movement. The exhaust flow rate Q ETA will then fluctuate between Q SET , MIN and Q SET , MAX based on the air quality.

[0047] When transitioning to the summer night ventilation mode the hygienic ventilation system will remove more air than it supplies and thus runs imbalanced to be able to realize the desired supply flows with the summer night vent 200-203. In the figure 4, the air exhaust flow Q ETA will be maximized to a level above the set ventilation range Q SET , MAX and thus use the excess capacity of the hygienic ventilation system to cool the building by ventilation. Thus, the air exhaust flow rate Q ETA will be consistent with the sum of the air supply flow Q HYG and the additional thermal flow Q THERM .

[0048] In an alternative function (not shown) one or more of the zonal exhaust air flows related to the auxiliary exhaust connections can be maximized to a level above the maximum set zonal ventilation flow rate, preferably to the ventilation capacity of the auxiliary connection or the auxiliary cooling passage connected to it.

[0049] The function of a hybrid ventilation system comprising the central hygienic ventilation system 100, a summer night vent 200 and a sensor for measuring a parameter related to the supply flow rate of outside air through the decentralized air supply installation is illustrated in figure 5. This sensor can be a part of the summer night vent 200, the central hygienic ventilation system 100 (such as the sensor of a control valve) or an external sensor that is present in a room of the building. It is foreseeable that one or more elements of the hybrid ventilation system can be controlled based on the measurements of one or more sensors, such as a combination of a sensor for the summer night vent 200, a summer night vent 200 for the hygienic ventilation system 100 and / or a room sensor.

[0050] Figure 5A shows receiving by a processor 150 of a signal S OPENED related to the opening of the summer night vent 200 and in reaction to this developing and sending of a signal S VENT related to the ventilative cooling using the hygienic ventilation system 100, for example a signal to change the ventilation mode or a signal to adjust the air flow rate.

[0051] The signal S OPENED may originate from the summer night vent 200 or an external sensor (not shown).

[0052] Figure 5B shows receiving by a processor 150 of a signal S COOL related to the changing of the ventilation mode of the hygienic ventilation system 100 to a summer night ventilation mode and in reaction to this developing and sending of a signal S OPEN related to the opening of the summer night vent 200.

[0053] Figure 5C shows developing and sending of the signal S VENT and developing and sending of a signal S OPEN . Here both parts are controlled by the processor 150 in reaction to an external action, meaning not originating from the hybrid ventilation system, for example through the manual activation by a user.List with reference numbers
