Description

Technical Field

[0001] This invention relates to a device for temperature regulation of two media, such as liquids and gases. Therefore, it particularly relates to domestic water and indoor air. Background Technology

[0002] Various devices for regulating the temperature of indoor air are known in the prior art. For example, there are different variations of heaters that can only heat indoor air. Alternatively, air conditioning equipment is known, which can cool or heat in relation to the direction of travel of its cooling circuit. If the focus is more on heating than cooling, they are also called heat pumps. Furthermore, air conditioning and heat pumps differ in that air conditioning equipment has two heat exchangers, which respectively transfer heat energy to or extract heat energy from the air. For air / air heat pumps, one heat exchanger is sufficient. Heat pumps with one side connected to brine are also known. Devices such as boilers or instantaneous water heaters are also known for heating liquids, such as water. In addition, devices that can heat not only air but also water are known. Here, determining how much heat energy is transferred to which medium can be difficult. Utility Model Content

[0003] The purpose of this invention is to provide a device for temperature regulation of at least two media, wherein the heat distribution can be set as precisely as possible.

[0004] This invention achieves the objective by means of a device for temperature regulation of two media, the device having at least one heat exchanger, at least two conveying devices and at least one temperature regulating device, wherein the first conveying device conducts the first medium whose temperature is to be regulated through the heat exchanger, wherein the second conveying device conducts the second medium whose temperature is to be regulated through the heat exchanger, wherein the temperature regulating device releases or removes heat energy, and wherein the temperature regulating device is directly or indirectly thermally coupled to the heat exchanger.

[0005] The device includes a heat exchanger, with a temperature regulating device indirectly or directly coupled to it. Direct coupling is achieved, for example, by placing the temperature regulating device at least partially within or at the heat exchanger. Indirect coupling is achieved, for example, by regulating the temperature of the working medium through the temperature regulating device, which is then introduced into the heat exchanger. The temperature regulating device serves as a heat source or heat sink. Therefore, heat energy is correspondingly introduced into or drawn from the heat exchanger, either indirectly or directly. Two conveying devices transport the two media through the heat exchanger, where they are correspondingly heated or cooled.

[0006] One design involves a heat exchanger having multiple plates and at least one conduction path—e.g., formed by at least one pipe or multiple pipes; the at least one conduction path—preferably laterally—guides through the plates; a spacing exists between adjacent plates; and a second conveying device is coupled to the spacing or the plate gap for a second medium whose temperature is to be regulated. In this design, the heat exchanger is implemented similarly to a finned heat exchanger. Here, multiple plates are present, spaced apart from each other. The outermost plates are generally referred to here as "endplates." Pipes guide through the plates. The pipes are connected to each other outside the endplates by bow-shaped members. The principle is known from air conditioning systems. In air conditioning systems, refrigerant flows along pipes and via elbows from one pipe to another. In this design, a conduction path—preferably implemented through at least a portion of the pipes—is provided, which guides through the plates. The conduction path is, for example, through which a first medium whose temperature is to be regulated flows. The second medium whose temperature is to be regulated is guided through the spaces between the plates. Therefore, in one design, the direction of movement of the second medium whose temperature is to be regulated extends particularly perpendicular to the direction of flow of at least one conduction path.

[0007] One design proposes a third conveying device that conducts the working medium through the heat exchanger, and a temperature regulating device that releases heat to or removes heat from the working medium. In this design, three media pass through the heat exchanger: two media to be regulated in temperature and the working medium. The two media to be regulated in temperature are, for example, indoor air and domestic water. The working medium reaches the desired temperature through the temperature regulating device, i.e., by heating by inputting heat energy or cooling by extracting heat energy. Three conveying devices transport the three media through the heat exchanger. Here, the two media to be regulated release their heat energy to the working medium cooled by the temperature regulating device or absorb heat energy from the working medium heated by the temperature regulating device. The design of the heat exchanger allows for pre-setting the corresponding heat transfer effects between the three media. Furthermore, the conveying capacity of each of the three conveying devices can be precisely set to determine the proportion of which medium for temperature regulation. Therefore, for example, it is possible to pre-set how much water and how much air to heat or cool. Thus, there are two separate pipe groups through two conduction paths. This allows, for example, control over which pipe group should participate in the heat exchange during application.

[0008] Specifically, the design scheme described above involves a heat exchanger with multiple plates and two conduction paths; the conduction paths guide through the plates, and a first conveying device is coupled to the first conduction path for a first medium whose temperature is to be regulated; a third conveying device is coupled to the second conduction path for a working medium; a gap exists between adjacent plates; and a second conveying device is coupled to the plate gap or spacing for a second medium whose temperature is to be regulated. This design scheme is an extension of the design scheme already discussed above. In this design scheme, the two conduction paths are arranged in the heat exchanger and are separate from each other. Therefore, if the heat exchanger has multiple pipes that pass through the plates, not all pipes are connected to each other, but only pipes belonging to the same conduction path are connected to each other. The working medium and the first medium whose temperature is to be regulated are guided through the two conduction paths. As in the design scheme above, the second medium whose temperature is to be regulated is guided through the plates.

[0009] A design scheme includes at least two conduction paths arranged side by side. This design scheme details how the conduction paths, for example, are not mutually enclosing, but rather independently arranged side by side. In this design scheme, the heat exchanger is, for example, a plate heat exchanger or a finned heat exchanger of an air conditioning unit, and its piping sections are modified for connecting pipes, such that two conduction paths of the aforementioned design scheme are derived from one conduction path. In this design scheme, the cost of manufacturing the heat exchanger is reduced.

[0010] One design involves a first conveying device designed as a pump for liquids or a compressor for gases, and a second conveying device designed as a fan for gases. This design details that the medium for which temperature is to be regulated is a liquid, such as water, or a compressed gas and other gases, such as room air. If the first medium for which temperature is to be regulated is, for example, a compressed gas, the gas is compressed by the first conveying device designed as a compressor so that it can subsequently condense in a heat exchanger.

[0011] In one design, the third conveying device is designed as a pump for liquids, a compressor for gases, or a fan for gases. Since the third conveying device conveys the working medium, in one design, the working medium can be a liquid, such as a coolant like liquefied propane, or a gas, such as carbon dioxide (CO2).

[0012] One design includes the device further comprising at least one electric heating element, which forms thermal contact with a heat exchanger. In this design, the heat exchanger has a separate heat source from which heat energy can be introduced. Another design includes an electric heating rod introduced into the plate, similar to the connection of pipes in the conduction path mentioned above.

[0013] The following two design schemes specifically discuss which function at least one heating element fulfills or which component it belongs to.

[0014] One design proposes that the device further include at least one electric heating element, which forms thermal contact with a heat exchanger. In this design, at least one electric heating element releases heat energy to be used in conjunction with a temperature regulating device for temperature regulation of both media.

[0015] Another design includes a temperature regulating device having at least one electric heating element, and the at least one electric heating element forming thermal contact with a heat exchanger. In this design, the temperature regulating device includes at least one heating element. In another design, the temperature regulating device may even consist of only one electric heating element or multiple electric heating elements.

[0016] In one design, an electric heating element is disposed in a heat exchanger and guided through the plates of the heat exchanger. If at least one conduction path in the form of a pipe is formed in the heat exchanger through the plates, then at least one electric heating element is disposed therein in the same or similar manner relative to the plates.

[0017] In one design, at least one electric heating element is implemented as a heating rod.

[0018] One design option involves the device also having a control unit. According to this design, the control unit acts on the first and / or second and / or third conveying devices, temperature regulating devices, and / or electric heating elements. The conveying devices can be configured to determine how much medium moves through the heat exchanger. Specifically, the flow rate can also be set to zero, so that, for example, no medium is conveyed in operating mode.

[0019] In one supplementary design, the flow rate of the first conveying device for the first medium whose temperature is to be regulated is kept constant. In an alternative design, the control unit controls the flow rate so that the first medium whose temperature is to be regulated, such as domestic water, has a constant discharge temperature.

[0020] One design option is to design the device as an air conditioning unit. This device specifically includes a compressor, condenser, expander, and evaporator, which form a refrigeration circuit. Such a cooling circuit can be used as a heat circuit in the opposite direction of operation. For example, the principle of air cooling by means of a cooling circuit is described in WO 2007 / 042065 A1. The aforementioned heat exchanger is preferably associated with the condenser or evaporator and thus is part of the temperature regulating device. According to the design option, the heat exchanger can absorb or release heat energy. In another design option, the second conveying device is a fan associated with the condenser or evaporator of the refrigeration circuit.

[0021] Therefore, in one design, the heat exchanger and the second delivery device belong to the air conditioning system. The second medium for temperature regulation is air, which is circulated through the heat exchanger by a fan, which acts as the second delivery device. In another design, a portion of the heat exchanger's piping is used to guide the first medium, in addition to the working medium, through the heat exchanger. Since the air conditioning system has both hot and cold heat exchangers, the first medium can be heated or cooled depending on which heat exchanger it is guided through, according to the design.

[0022] In an alternative design, the temperature control device is implemented as a heat pump. Attached Figure Description

[0023] Various possibilities for designing and improving the device according to this utility model are given in detail. This is described in conjunction with the following description of the embodiments and the accompanying drawings. The drawings show:

[0024] Figure 1 A schematic diagram of a design scheme of the device according to the present invention is shown;

[0025] Figure 2 A schematic diagram of the first design scheme of the heat exchanger is shown;

[0026] Figure 3 A schematic diagram showing a second design scheme for the heat exchanger; and

[0027] Figure 4 A schematic diagram of the third design scheme for the heat exchanger is shown. Detailed Implementation

[0028] Figure 1 The schematic illustration shows an example of the device's construction, matching, for example... Figure 3 The heat exchanger 1 shown is as described.

[0029] Temperature regulating device 20 regulates the temperature of the working medium. Temperature regulation can, in principle, be heating or cooling. For the purposes of this observation, the working medium is a liquid. Correspondingly, this applies to cases where the working medium is a gas. In the illustrated design, temperature regulating device 20 can heat the working medium.

[0030] The third conveying device 4 is a pump that pumps the working medium through the heat exchanger 1. Preferably, a loop (not shown) is formed such that the working medium returns to the temperature regulating device 20 after passing through the heat exchanger 1. Inside the heat exchanger 1, the working medium releases its heat energy onto the two media whose temperatures are to be regulated. Therefore, both media are heated in the illustrated embodiment.

[0031] For this heat transfer purpose, two additional conveying devices 2 and 3 are provided, which transport the two media through the heat exchanger 1 via a first conduction path 11 and a second conduction path 12. The first conveying device 2 for the first medium whose temperature is to be regulated is, in this example, a liquid pump for transporting water. It is shown here that the working medium and the first medium are guided through the heat exchanger 1 substantially parallel to each other. This parallel arrangement... Figures 2 to 4 The embodiments are shown. The second conveying device 3 for the second medium is a fan. It is shown here that air, as the second medium, is guided substantially vertically through the heat exchanger 1. Different directions of movement are indicated by arrows, with liquid represented by solid lines and air by dashed lines.

[0032] The heat exchanger 1 additionally includes an electric heating element 6, which is positioned near the conduction path of the first medium to transfer additional heat energy to the water and / or the working medium. The heating element 6 may also optionally be used to heat the flowing gas.

[0033] The three conveying devices 2, 3, and 4, the heating element 6, and the temperature regulating device 20 are controlled by the control unit 5. In a variant form, the control unit 5 regulates components 2, 3, 4, 6, and 20 so that the water and / or air each have a desired temperature value. If, for example, the water should be set to a desired temperature, temperature regulation can be performed via the second conveying device 3, i.e., via the air volume. The greater the conveying power of the second conveying device 3, the more air is guided through the heat exchanger 1, and the less heat energy is supplied to the water. Therefore, if the working medium has more heat energy than the water requires, the heat of the water can be set relatively simply and reliably via the regulation of the fan 3.

[0034] Diagram Figures 2 to 4 The heat exchanger 1 is shown purely schematically and is not intended as a specific example of the geometry or number of the components or parts involved, or to be construed as a limitation of this disclosure.

[0035] exist Figure 2 As shown in the diagram, the temperature regulating device 20 is provided in the form of a heating rod via an electric heating element 6 (shown in white here). Therefore, the temperature regulating device 20 is located directly in the heat exchanger 1 as a conduit for conduction path 11 and is guided through its plate 13.

[0036] The heat exchanger 1 here is a so-called finned heat exchanger, which has a plurality of heat-conducting plates 13 spaced apart from each other by a spacing 14. Air, as a second medium for temperature regulation, is guided through the spacing 14. Multiple pipes 11 extend through the plates 13. The pipes guide the first medium for temperature regulation multiple times through the heat exchanger 1 in a first conduction path 11 (marked here by a grid). Elbows, which connect the pipes of the first conduction path 11 to each other, are not shown here. As can be seen, the first conduction path 11 and the electric heating element 6 are arranged side by side.

[0037] exist Figure 3 In a variant form, heat exchanger 1 is shown to be a component of temperature regulating device 20. Temperature regulating device 20 is implemented here as an air conditioning unit, such that refrigerant is also guided through heat exchanger 1, the compression and expansion of which are used to transfer heat energy. In heat exchanger 1, a first medium to be cooled, i.e., water, is guided in a first conduction path 11 (marked here by a grid). Parallel to and separate from this first conduction path 11 exists a second conduction path 12, through which the working medium (see [reference needed]) is transported. Figure 1 (This is marked with a slash). Similarly, there is an electric heating element 6 in the form of a heating rod, which exists parallel to it. Its heating power can be used to supplement the heating power in the temperature regulation direction or as a regulator.

[0038] Therefore, in Figure 3 In the aforementioned design, the transfer of heat energy from which medium to which medium and in what quantity can be precisely controlled via the three conveying devices 2, 3, and 4, the electric heating element 6, and preferably the temperature regulating device 20. This is achieved by using the temperature regulating device 20 and the electric heating element 6, which, in addition to being combined, can also switch between heat sources.

[0039] The basic transport paths for a pair of heat examples are as follows, and they can also be combined with each other:

[0040] 1) Heat transfer occurs between two media (i.e., the first medium to be regulated and the working medium) in the two conduction paths 11 and 12. This is achieved by convection of one medium in the pipes of conduction paths 11 and 12, followed by heat conduction through the plates 13 located between the pipes in the plates 13, and finally convection from the pipes of the other conduction path 12 and 11 to the medium located therein. In this way, for example, heat energy can be transferred from the working medium to the first medium to be regulated. However, if, for example, the first medium to be regulated is overheated, this can also be reversed.

[0041] 2) Heat is transferred from at least one of the two conduction paths 11, 12 to the air, which is the second medium for which the temperature is to be regulated. The transfer can also proceed in reverse. Here, the medium transfers heat energy via convection to the pipes that guide it. The pipes transfer heat energy via thermal conduction to the plates 13 of the heat exchanger 1. The heat energy is then transferred via convection to the air passing between the plates 13. If, for example, heat energy should be transferred from the air to only one medium, then, for example, the other medium is not transported through its conduction path, but only the desired medium is transported.

[0042] 3) The electric heating element 6 transfers heat energy to at least one of the media in the conduction paths 11 and 12. It should be noted that, for example, if the associated conveying equipment is not operating and therefore no medium is being conveyed, one of the two media cannot be heated. The heat energy generated by the resistance is transferred to the plate 13 via thermal conduction and from there to the pipes of the corresponding conduction paths 11 and 12. The pipes of conduction paths 11 and 12 then transfer the heat to the corresponding media via convection.

[0043] 4) The electric heating element 6 is used to heat the air, which is the second medium for which the temperature is to be regulated. Here, the heating element 6 transfers thermal energy, i.e., heat generated by resistance, to the fins 13 through thermal conduction, and from the fins, the thermal energy is transferred to the air through convection.

[0044] For example, if the working medium is cooled or the temperature control device 20 acts as a heat sink, the above mode also applies to cooling. Here, the electric heating element 6 can be used, for example, to compensate for excessively low outlet temperatures of the temperature control device 20. In cooling applications, the working medium is, for example, a refrigerant commonly used in air conditioning equipment.

[0045] Figure 4 A variant of the heat exchanger 1 is shown, wherein the working medium, a first medium (marked with grids) whose temperature is to be regulated, is guided through a second conduction path 12 (marked with diagonal lines) parallel to the first conduction path 11. Air, which is a second medium whose temperature is to be regulated, is also guided through the plate 13 perpendicular to the conduction paths 11 and 12.
