Description

The invention relates to a building interior conditioning system, in particular for low-energy houses.

Buildings and their building interiors serve man primarily to protect against environmental impacts. At the same time, they should create an environment for the person, in which he can retire for relaxation and recreation. The relaxation and recuperation effect depends primarily on the quality of the building interior and the prevailing indoor climate in this building. The interior climate of the building is in particular dependent on the temperature of the room air and the room-enclosing surfaces, the physical and chemical properties of the air and the temperature profile of the space-enclosing surfaces. The indoor climate of the building is therefore determined largely by the factors temperature, water vapor content, movement and purity of the air as well as the temperature of the room-enclosing surfaces. Basic terms for the assessment of a building interior climate are the comfort or the feel-good climate. To achieve this comfort, various systems are used in current building construction. In general, these are the classic heating systems such as oil and gas heating, district heating, heat pumps, solar thermal collectors and pellet heating, where mostly water is used as the heat transfer medium, with a relatively high energy consumption for circulation of the water is obtained as a heat transfer medium. In particular, underfloor heating or radiators are tempered with such systems, which then deliver the heat to the interior.

Due to the ever-increasing requirements of the Energy Ordinance, a high degree of airtightness is assumed for the building envelope. The automatic air exchange between the building interior and the outside environment is largely prevented.

Due to this tightness and high thermal insulation controlled ventilation to provide the required air exchange are used by the prior art, by which an uncontrolled heat loss should be avoided by manual ventilation. The functions of the controlled ventilation usually take over central ventilation systems with heat recovery from the exhaust air. However, according to their design principle, conventional ventilation systems only provide for a pre-tempered ventilation of the building interior. To cover the required heat demand thus additional, conventional heat source in the form of the above-described radiators or underfloor heating must be used. This results in particular the disadvantage that the heating systems and the ventilation systems are usually solitary, so controlled independently and work so that a feel-good climate with such systems is not or only partially providable.

The object of the present invention is therefore to provide a system for conditioning a building interior, which overcomes the disadvantages of the prior art, which is susceptible to interference and has a high energy efficiency and ensures a high level of comfort and a healthy living environment inside the building.

The object is achieved by a system having the features listed in claim 1. Preferred developments emerge from the subclaims.

An inventive building interior conditioning system has a ventilation and tempering unit, a hypocaust unit, an exhaust air duct and a sensor unit.

In the present case, the ventilation and tempering unit comprises a KWL unit (controlled ventilation of the living space) and a rear-mounted heat exchanger, wherein a supply air for the building interior can be provided by means of the KWL unit and an exhaust air can be discharged from the building interior. The KWL unit is designed here as a central ventilation unit, each with an input for outdoor air and exhaust air, as well as with an outlet for exhaust air and supply air and with a heat recovery from the exhaust air. The heat recovery takes place here in a known manner by means of a cross-heat exchanger. The supply air which can be provided by the KWL unit is inventively feasible by the Nachschaltwärmetauscher and tempered by means of this. The Nachschaltwärmetauscher this example, connected to a heat pump, through which the necessary heat energy for temperature control of the supply air can be provided. Optionally, in a cooling operation, heat energy of the supply air can be withdrawn by the heat pump for its temperature control.

Moreover, according to the invention, the ventilation and tempering unit is air-conductively connected to the hypocaust unit so that the supply air that can be supplied can be delivered from the ventilation and tempering unit to the hypocausal unit.

The Hypokausteneinheit is inventively formed by a Bodenhypokaustenelement and a Wandhypokaustenelement, which also summarized below as Hypokaustenelemente be designated and which can be formed by a plurality of interconnected Hypokausteneinzelelemente. The supply air which can be provided by the ventilation and temperature control unit is inventively guided through the Bodenhypokaustenelement and then through the Wandhypokaustenelement, wherein a heat exchange between the supply air and the Bodenhypokaustenelement and subsequently also between the supply air and the Wandhypokaustenelement can be provided during the supply air.

Depending on the temperature of the supply air, the heat exchange takes place here in the form that either stored in the supply air heat is released to the Hypokaustenelemente or stored in the Hypokaustenelementen heat to the supply air. In this way, heat can be supplied to the hypocausting elements, for example in a heating operation, or removed from them in a cooling operation. As far as neither heating nor cooling is desired, there may also be a thermal equilibrium without heat exchange.

At the same time, the hypocausal elements are designed such that a heat exchange can be provided between them and an interior of a building, the heat exchange being effected at least partially by means of radiant heat. Thus, the interior can be supplied to the interior via the Hypokaustenelemente in a heating operation heat. Conversely, heat can be released from the interior to the hypocaustite elements in a cooling operation.

In the present case, the wall honeycomb element is characterized in particular in that it has an inlet air outlet which is arranged in an upper third of the room height of the interior space and via which the supply air provided by the ventilation and temperature control unit and guided through the hypocaust surface elements can be introduced into the interior.

In particular, in a heating operation, a particular advantage of the system according to the invention is that the comfort is improved without additional measures. This is made possible by the system in that the heated supply air during their tour through the Hypokaustenelemente successively transfers the heat to this, while cooling itself sukessive. Thus, the bottom hypocausal member and the bottom portion of the wall hypocausal member are tempered a little higher than the top portion of the wall hypocausal member, which contributes to an improvement in comfort by keeping a user's feet pleasantly warm while buffing the head with less lateral heat of radiation. At the same time the air is released relatively cooled. This also contributes to the improvement of the comfort by the head area is not blown too warm air and also by the positioning of the Zuluftauslasses in the upper third of the fresh air supply is near the head of a user available.

The exhaust air present in the interior is supplied according to the invention via the exhaust air duct of the ventilation and temperature control unit. For this purpose, the exhaust air duct has an exhaust air outlet, which is arranged in the interior in a lower third of its ceiling height. Due to the opposing arrangement of the exhaust outlet relative to the Zuluftauslass a particularly good ventilation of the interior is provided as a particular advantage of the invention, since the supply air flows through the interior diagonally. At the same time, a thermal zoning from above cool down warm is supported. At the same time, the arrangement of the exhaust air outlet causes a particularly good calming of the air movement, in particular caused by the supply air, in the interior, so that a pulling sensation in the interior can be largely prevented. The exhaust air outlet may preferably be formed by a ventilation opening in a room door or by a sufficient air gap under the room door. In this case, for example, an adjacent corridor as an overflow area and, for example, a bath as a take-off area are part of the exhaust air duct. But it is also possible to arrange the exhaust outlet in an inner wall and drain the drain directly to the ventilation and temperature control unit.

In the present case, the sensor unit of the system according to the invention is capable of detecting indoor air data of the interior and transmitting it to the ventilation and temperature control unit. In particular, the room air temperature, the room air humidity and the CO2 content of the room air are recorded as room air data.

Optionally, it is also possible to use the sensor unit simultaneously as a flue gas detector, so that can be dispensed as a particular advantage to a separate smoke detector in the interior.

By means of the transferred room air data, operating states of the ventilation and temperature control unit can be controlled according to the invention. In this context, for example, the temperature of the Nachschaltwärmetauschers depending on the room temperature or the intensity of the supply air flow into the interior depending on the humidity of the room can be variably adjusted.

The system of the invention provides several advantages.

A first particular advantage of the invention is that with a uniform system, both an interior temperature control and an active air duct is provided. On the use of the usual additional Zuheizvorrichtungen, such as radiators or underfloor heating or on additional air conditioning units for controlling the temperature of the interior, can be advantageously dispensed with.

This is associated with the advantage that only a motor unit to ensure the air flow, as well as to realize the movement of the heat transfer medium is needed. Furthermore, in connection with the integration of the sub-functions of the ventilation and temperature control, there is an advantage in that both partial functions are uniformly detected by control technology and can not work against each other or require complex coordination.

Another advantage is that air is used as the heat transfer medium, so that a trouble-free, leak-proof operation is possible

Furthermore, there is an advantage that, despite the use of air as the heat transfer medium but the typical disadvantage of hot air heaters that locally relatively high temperature air is blown, is overcome.

This is associated with the advantage that a heat release takes place over a large area and by means of radiant heat.

In addition, there is an advantage in that the tempering and ventilation operation of the system is optimized for the physiology and well-being of humans by introducing the majority of the radiant heat in the area of a lower ceiling height of the interior and the supply air in the interior in the area of a greater room height. In this way, an otherwise conventional and tends to be perceived as unpleasant thermal zoning in an interior of cold in low ceiling heights is counteracted too warm in large room heights advantageous.

Another advantage with regard to the comfort is the achievement of a homogenization of the floor and wall temperatures, but also the room air temperatures by the permanent inclusion of the high heat storage mass of Hypokausteneinheit.

Another advantage is the special energy efficiency. The particular energy efficiency is brought about by the following advantageous factors: The large-scale temperature control of the floor and wall surfaces provides comfort even at relatively low air temperatures. The transmission heat losses and the losses due to the air exchange are thus reduced. Due to the large-scale temperature control of the floor and wall surfaces, the supply air must be acted upon as a heat transfer medium only with relatively low temperatures; As a result, the efficiency increases and also heat sources low temperature levels can be used efficiently, such as solar thermal energy even at low solar radiation. With the Hypokausten unit, a high heat storage mass is permanently active. Especially in the case of large outside temperature fluctuations, the supply air discharged into the interior remains for a longer time at a still perceived as pleasant temperature level without having to be heated by energy consumption on the Nachschaltwärmetauscher or cooled using energy.

In a preferred development of the system, the ventilation and tempering unit has a feed element, a bypass and at least one mixing chamber.

The Zuluftstellelement is in this case arranged between the KWL unit and the Nachschaltwärmetauscher and to be able to initiate the supply of air through the KWL plant supply into the bypass.

The bypass, in turn, according to the invention is designed such that it allows a passage of the supply air to the Nachschaltwärmetauscher.

Further, in the present case, the mixing chamber is connected to the bypass and the Nachschaltwärmetauscher and to be able to mix the supply air from the Nachschaltwärmetauscher and the supply air from the bypass with each other, the mass flow rates of the respective supply air through the mixing chamber are variably adjustable. The supply air which can be provided in this way can then be delivered from the mixing chamber to the hypokausal unit, it being possible to provide the desired temperature of the supply air delivered to the hypocaustical unit by adapting the supply air mass flows through the mixing chamber. In this case, it is possible, for example, to supply exclusively the supply air from the secondary heat exchanger of the hypokausten unit in a heating operation through the mixing chamber or this supply air, in particular in the case of a permanently set operating state of the secondary heat exchanger, in which it generally emits the supply air at a specified temperature, with the supply air To mix the bypass and thus provide a particularly rapid adjustment of the supply air temperature.

Alternatively, in the present case it is also possible to dispense through the mixing chamber only the supply air from the bypass to the Hypokausten unit, so as to provide in particular an operation of the system without heating. In this case, there is the particular advantage of the arrangement of the bypass present in particular in the direct supply of the low-temperature supply air in the Hypokausteneinheit and in the interior and in the so-releasable removal of unwanted heat from the interior.

A further advantageous variant of the system that this at least one further Hypokausteneinheit, at least one further exhaust outlet and at least one further sensor unit has, which are assigned to a further interior and that the ventilation and temperature control unit also has at least one further mixing chamber.

The at least one further mixing chamber is presently also connected to the Nachschaltwärmetauscher and the bypass and allows the delivery of the supply air to the at least one further Hypokausteneinheit, via which the supply air is subsequently deliverable to the other interior.

By means of the at least one further sensor unit, in this case room air data of the further interior is detected and transmitted to the ventilation and temperature control unit for controlling the operating states. On the basis of the room air data, the ventilation and tempering unit is in particular capable of correspondingly regulating the operating state of the at least one further mixing chamber in such a way that it delivers the supply air with the corresponding desired temperature to the at least one further hypocaustical unit. Compared with conventional solutions for domestic ventilation, the system has in the variant listed here in particular the technological advantage that the ventilation and temperature control of the at least two interiors independently and thus a variable single room ventilation and temperature control can be provided by the variable operation of at least one further mixing chamber.

Preferably, with a corresponding number of all other components for each interior a separate control of ventilation and temperature control is possible.

In a further advantageous variant of the system, the ventilation and temperature control unit has a heat exchanger and an outdoor air control element, wherein by means of the geothermal heat exchanger an outside air can be pre-tempered and can be delivered to the HCW unit via the outside air control element.

In this case, the outside air control element is able either to deliver the outside air preheated by the geothermal heat exchanger directly to the KWL unit or to mix it with ambient outside air before it is discharged. In this case, the mass flows of the pre-tempered outside air and the outside ambient air are preferably infinitely variably adjustable by the outside air control element, so that the outside air control element can deliver the outside air to the KWL unit at a desired temperature.

The geothermal heat exchanger additionally increases the energy efficiency of the system. In a cooling operation, relatively cool supply air can be provided without the temperature being controlled using energy. In a heating operation at very low outside temperatures, the supplied air can be preheated, so that less energy has to be expended for heating by means of the Nachschaltwärmetauschers.

The KWL unit 5 is presently designed as a central ventilation unit with a cross-heat exchanger (not shown) and allows in a known manner a temperature control of a supplied outside air by means of a through the exhaust air duct 3 supplied exhaust air from the interior 9 , The tempered outside air is through the KWL unit 5 provided as supply air. The general mode of operation of a KWL unit is assumed to be known to the person skilled in the art and therefore not explained in detail.

Furthermore, the ventilation and temperature control unit includes 1 a secondary heat exchanger 6 which by the KWL unit 5 Provable supply air can be supplied. The secondary heat exchanger 6 is present with a heat pump 20 connected and by means of the heat pump 20 Provable heat energy to be able to supply the supplied air to a for the temperature control of the interior 9 necessary temperature level to heat. In the exemplary embodiment, the heat pump can also be operated in the cooling mode, so that then heat energy of the supply air from the Nachschaltwärmetauscher can be received and dissipated to the heat pump.

The through the Nachschaltwärmetauscher 6 tempered supply air is present from the ventilation and temperature control unit 1 to the hypocausal unit 2 deliverable, by means of which the heat energy contained in the supply air to the interior 9 can be fed.

The control of the ventilation and temperature control unit 1 takes place here based on indoor air data of the interior 9 passing through the sensor unit 4 preferably continuously detected and to the ventilation and temperature control unit 1 be transmitted. In particular, the interior temperature, the indoor air humidity and an oxygen and / or carbon dioxide content of the indoor air are detected as room air data. For processing the room air data has the ventilation and temperature control unit 1 in the present case, a control and evaluation unit (not shown), which is capable of, on the basis of the room air data corresponding control signals, in particular for the KWL unit 5 and the secondary heat exchanger 6 , or the heat pump 20 to generate and transmit to these components of the system.

In the first embodiment of the system, the ventilation and temperature control unit 1 as in the 1 and 2 shown, a Zuluftstellelement 12 as well as a bypass 13 on. The Zuluftstellelement 12 is able to do this through the KWL unit 5 Provisionable supply air at least partially in the bypass 13 derive, by means of which the supply air then to the Nachschaltwärmetauscher 6 is passable. Furthermore, in the embodiment shown here, the system has a mixing chamber 14 on which the Nachschaltwärmetauscher 6 downstream and with the bypass 13 connected is. The mixing chamber 14 is presently equipped with a three-way control valve (not shown) and capable of either either by the Nachschaltwärmetauscher 6 Provable supply air or through the bypass 13 Guidable supply air directly to the Hypokausten unit 2 or the two supply air streams before delivery to the Hypokausteneinheit 2 to mix. That way it gets through the bypass 13 and the mixing chamber 14 effected in a particularly advantageous manner, on the one hand, as needed, the supply air without temperature control by the Nachschaltwärmetauscher 6 directly for the hypocaustic unit 2 can be provided and that on the other hand by mixing the supply air flows in the mixing chamber 14 a particularly rapid adjustment of the supply air temperature is made possible. As a result of the rapid adaptability thus enabled, system-dependent inertia of the secondary heat exchanger can be achieved, in particular if the supply air temperature is lowered 6 be overcome.

In the illustrated embodiment of the system has the ventilation and temperature control unit 1 a geothermal heat exchanger 15 and an outside air actuator 16 on. By means of the geothermal heat exchanger 15 In the present case, an outside air can be pre-tempered, which is subsequently passed through the outside air control element 16 the KWL unit 5 can be fed. The outdoor air control element 16 is able to do this, depending on the needs, through the geothermal heat exchanger 15 Pre-tempered outside air directly from the KWL unit 5 to supply or previously with one, via an ambient outside air supply 18 deliverable, ambient ambient air to mix in order to provide a desired temperature level of the outside air in this way. Depending on requirements, it is also possible that the outdoor air actuator 16 only the ambient outside air as outside air of the KWL unit 5 supplies.

The 2 shows in a further embodiment, the system with two mixing chambers 14.1 and 14.2 as well as two hypocaust units 2.1 and 2.2 and two exhaust air outlets 11.1 and 11.2 Each of these components each having an interior space 9.1 and 9.2 assigned.

The mixing chambers 14.1 . 14.2 are present in each case with the Nachschaltwärmetauscher 6 as well as with the bypass 13 connected and allow in this case the supply of supply air to the respective associated Hypokausteneinheit 2.1 or 2.2 , In this way, a single room ventilation and temperature control is provided as a particular advantage by the system, in which, by a variable adjustment of the supply air flows of the Nachschaltwärmetauschers 6 and the bypass 13 through each of the mixing chambers 14.1 and 14.2 , two interiors 9.1 and 9.2 independently of each other can be ventilated and tempered. The room air data required for independent ventilation and temperature control are provided by two separate sensor units 4.1 and 4.2 detected, wherein the sensor unit 4.1 the interior 9.1 and the sensor unit 4.2 the interior 9.2 is assigned and wherein the sensor units 4.1 and 4.2 each with the ventilation and tempering unit 1 are connected.

The 3 shows a hypocaust unit 2 of the system according to the invention as part of an interior in a sectional schematic representation.

The hypocaust unit 2 in this case has a Bodenhypokaustenelement 7 and a wall hypocaust element 8th on. The through the ventilation and temperature control unit 1 Provable supply air is present in the Bodenhypokaustenelement 7 einbringbar and through this into the Wandhypokaustenelement 8th feasible. During the passage of the supply air through the Hypokausten unit 2 is in a heating operation of the system, the heat energy contained in the supply air in the form of radiant heat delivered to the interior, whereby the supply air on the way through the Hypokausteneinheit 2 cools. The release of heat energy in the form of radiant heat decreases with increasing Durchströmweg through the Hypokaustenelemente 7 and 8th , which is exemplified by the increasing distance of directed into the interior arrows.

The wall hypocaust element 8th in this case has a Zuluftauslass 10 on, through which the cooled supply air flows into the interior and thus assumes the function of ventilation. The supply air outlet 10 is presently arranged in an upper third of the ceiling height of the interior, whereby the cooled fresh air in this area can be introduced into the interior.

At the same time is in one, preferably the Wandhypokaustenelement 8th opposite, wall portion of the interior of an exhaust outlet 11 arranged over which the indoor air can be discharged as exhaust air. In the exemplary embodiment, the exhaust outlet is arranged in an inner wall in a lower region. In a variant of this embodiment, not shown, the exhaust air outlet is designed as a ventilation opening in a lower region of a room door. In contrast to the supply air outlet 10 is the exhaust outlet 11 arranged in a lower third of the ceiling height of the interior, so that an air flow through the interior is adjusted from top to bottom and so a particularly effective ventilation of the interior is available. Another advantage of the arrangement of Zuluftauslasses 10 and the exhaust outlet 11 There is also the fact that the indoor air can be calmed very well and set in this way no perceived as uncomfortable air movements in the interior.

Due to the design and arrangement of the Bodenhypokaustenelements 7 and the Wandhypokaustenelements 8th becomes through the hypocausal unit 2 realizes a particularly advantageous tempering and ventilation behavior, in which the majority of the heat energy in the range of a smaller room height in the interior can be issued and in which at the same time necessary for the ventilation supply air in the upper part of the room height is introduced into this. Such a Temperierungs- and ventilation behavior is perceived by a person staying in the interior, usually as particularly pleasant, since the largest entry of heat energy into the interior of the foot and leg area and on the other hand in the head area less radiant heat and instead the Zulufteintrag he follows. In particular, the desired feel-good climate can be provided in this way even when the person is sitting.
