Description

Field of the Invention

[0001] The present invention relates to a computer-implemented method for controlling the indoor climate of a residence performed by a data processing apparatus. The present invention further relates to a system for controlling the indoor climate of a residence.Background

[0002] Systems for controlling the indoor climate of a residence are known. For example, solar shading systems, ventilation systems, ventilative cooling systems, air-conditioning systems and heating systems. Often multiple types of indoor climate systems are present in a residential building. However, integrating and coordinating these various systems to work together efficiently can be challenging. Each system typically operates independently, using its own set of sensors, controls, and user interfaces. This lack of integration can lead to inefficiencies, e.g. multiple (redundant) sensors that measure the same quantities (temperature, co2, humidity, outdoor temperature), and suboptimal indoor climate conditions, as the systems might counteract each other rather than complement one another. For example, an air-conditioning system might cool a room while a heating system simultaneously heats another part of the same residence, resulting in wasted energy. Similarly, a ventilation system might work against a ventilative cooling system if they are not properly synchronized, causing unnecessary energy consumption and discomfort.Object of the Invention

[0003] An object of the invention is to provide a single control unit that manages all indoor climate systems, allowing for coordinated operation and user-friendly management. Another object of the invention may be to utilize advanced sensors that can monitor various environmental parameters (temperature, humidity, air quality, etc.) throughout the residence. A further object of the invention may be to automatically adjust system operations based on real-time data from the sensors, optimizing comfort and energy efficiency.Summary of the Invention

Detailed Description of Embodiments

[0014] The present disclosure will be described with respect to particular embodiments and with reference to certain drawings but the disclosure is not limited thereto but only by the claims. The drawings described are only schematic and are non-limiting. In the drawings, the size of some of the elements may be exaggerated and not drawn on scale for illustrative purposes. The dimensions and the relative dimensions do not necessarily correspond to actual reductions to practice of the disclosure.

[0015] Furthermore, the terms first, second, third and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. The terms are interchangeable under appropriate circumstances and the embodiments of the disclosure can operate in other sequences than described or illustrated herein.

[0016] Moreover, the terms top, bottom, back, front and the like in the description and the claims are used for descriptive purposes and not necessarily for describing relative positions. The terms so used are interchangeable under appropriate circumstances and the embodiments of the invention described herein can operate in other orientations than described or illustrated herein.

[0017] Furthermore, the various embodiments, although referred to as "preferred" are to be construed as exemplary manners in which the disclosure may be implemented rather than as limiting the scope of the disclosure.

[0018] The term "comprising", used in the claims, should not be interpreted as being restricted to the elements or steps listed thereafter; it does not exclude other elements or steps. It needs to be interpreted as specifying the presence of the stated features, integers, steps or components as referred to, but does not preclude the presence or addition of one or more other features, integers, steps or components, or groups thereof. Thus, the scope of the expression "a device comprising A and B" should not be limited to devices consisting only of components A and B, rather with respect to the present disclosure, the only enumerated components of the device are A and B, and further the claim should be interpreted as including equivalents of those components.

[0019] Different aspects of the present disclosure will be described more fully hereinafter with reference to the enclosed drawings. The embodiments disclosed herein can, however, be realized in many different forms and should not be construed as being limited to the aspects set forth herein.

[0020] Fig. 1 shows a building 1 in the form of a house consisting of multiple rooms 11, 12, 21, 22, and a circulation space 30, such as a corridor, hall, or landing, which allows access to the rooms. The building 1 depicted in Fig. 1 has several living spaces 11, 12 in the form of rooms, such as a living room or a bedroom, to which supply air, SUP, can be delivered through the supply air ducts 2, 3. Additionally, stale air, ETA, can be extracted through return air ducts 4, 5 from functional spaces 21, 22 in the form of rooms, such as a toilet room, a bathroom, or a kitchen. Each of these ducts 2, 3, 4, 5 is connected to a respective connection 113, 114; 123 of a ventilation system 100. With one or more distributors (not shown), multiple similar ducts can simultaneously be connected to a single connection. The building further includes an outside air duct 6 for supplying outside air, ODA, to an outside air connection 112 of the hygienic ventilation system 100 and an exhaust air duct 7 for the discharge of exhaust air, EHA, from an exhaust air connection 122 of the ventilation system 100. The building is further provided with one or more, in the illustrated embodiment three, other indoor climate systems 40, 50, 60. For example, dynamic exterior solar shading 40, a natural ventilation system or ventilative cooling system 50, or an air conditioning system 60. Dynamic exterior solar shading includes (windproof) screens and exterior blinds, articulated arm awnings, dropdown screens and roller shutters. Structural solar shading includes slats, sliding and folding screens as well as awnings.

[0021] An embodiment of the ventilation system 100, with mechanical air exhaust and mechanical air supply, is shown in Fig. 2A. This ventilation system 100 has a housing, indicated as 101, with an outside air connection 112 to which the outside air duct 6 from Fig. 1 can be connected. Furthermore, the hygienic ventilation system has an exhaust air connection 122 to which the exhaust air duct 7 can be connected. At the other end of the housing, there are one or more, in the illustrated embodiment two, supply air connections 113, 114 and one or more, in the illustrated embodiment one, return air connections 123. Between the outside air connection 111 and the supply air connections 113, 114, the supply flow passage 110 extends. Similarly, between the return air connections 123 and the exhaust air connection 121, the exhaust flow passage 120 extends. In these supply flow passages 110 and exhaust flow passages 120, a heat exchanger, indicated as 130, can be placed, which ensures that energy can be exchanged between the supplied and exhausted air. Additionally, a recirculation device 140, 141, 142 is provided to allow the air supply flow to partially or fully recirculate the heat exchanger in the supply flow passage 110. The supply and exhaust of air are carried out by the two fans 111, 121, one of which is placed in the supply flow passage 110 and the other in the exhaust flow passage 120.

[0022] Another embodiment of a hygienic ventilation system 200, which uses mechanical extract fans to remove stale air while allowing fresh air to enter through natural means, is shown in Fig. 2B. This hygienic ventilation system 200 has a housing shown by 201 with an exhaust air connection 222 to which the exhaust air duct 7 can be connected. At the other end of the housing, there are one or more, in the illustrated embodiment three, return air connections 223-225. The exhaust plenum 220 extends between the return air connections 223-225 and the exhaust air connection 222. The output of air takes place using the booster 221 that is placed in the exhaust plenum 220 near the main exhaust connection 222.

[0023] In the basic version of the hygienic ventilation system 100, the air flows to the various spaces depending on the resistance in the various ducts, without any further possibility for regulation, and is extracted from them accordingly. To provide the possibility for a desired distribution of the air, hygienic flow controllers (not shown) can be placed in the connections. Each flow controller can be housed in a cassette, which in turn is housed in a cassette chamber located at or behind the respective air supply air connection. Each cassette may further have a measurement system, which can include, for example, a sensor for measuring the CO2 level of the air, relative humidity, and the like. An internal or external control unit or processor 150 is configured to control, independently of each other, on the one hand, the supply fan 111, and on the other hand, the exhaust fan 121. The control of these elements will depend on the ventilation condition of the hygienic ventilation system. In the basic version of hygienic ventilation system 200, processor 250 is configured to control the exhaust fan 221 and optional hygienic flow controllers in the return air connections 223-225.

[0024] Figures 3 shows a flowchart illustrating a method 300 of controlling the indoor climate of the residence, e.g. the residence shown in figure 1, according to an embodiment of the present invention. At operation 310 sensed data is received in the ventilation system 100, 200. The sensed data is associated with the climate in the residence, weather outside the residence and / or occupants of the residence. Based at least in part on the received sensed data associated with the climate in the residence, desired settings of two or more indoor climate systems 40, 50, 60 are determined at operation 320. At operation 330 it is determined that the desired settings are different compared to current settings of the two or more indoor climate systems. And after determining the desired settings are different to the current settings, the ventilation system 100, 200 sends instructions associated with the desired settings to the indoor climate systems 40, 50, 60 at operation 340.

[0025] Alternatively, illustrated in method 400 shown in figure 4, operation 320 may be replaced by operations 410-430. At operation 410, the climate in the residence is determined based at least in part on the received sensed data associated with the climate in the residence. Thereafter, it is determined that that the climate in the residence has changed compared to the previous climate at operation 420, or that the outside weather or the occupancy of the residence has changed. At operation 430, the desired settings of two or more indoor climate systems are determined based at least in part on the received sensed data.
