Summary of the Invention

Problems to be Solved by the Invention

[0004] The problem of the present invention is to provide a temperature control device for a vehicle with a prime mover and a vehicle with a prime mover having such a temperature control device so that particularly advantageous temperature control, that is, cooling (air conditioning) and / or heating (warming), can be achieved.

Means for Solving the Problems

[0005] This problem is solved by the present invention by a temperature control device having the features of claim 1 and a vehicle with a prime mover having the features of claim 10. Advantageous configurations of the present invention are the subject of the dependent claims.

[0006] A first aspect of the present invention relates to a temperature control system or temperature control device, or a temperature control device formed as a temperature control system or temperature control device. A motorized vehicle is formed by a motorized vehicle structure, where the interior space, also called the occupant cabin or occupant space, is preferably configured as a self-supporting body of the motorized vehicle, and is also called a vehicle, preferably as an automobile, particularly as a passenger car. Preferably, the motorized vehicle is configured as an electric vehicle, particularly a battery electric vehicle (BEV), so that the motorized vehicle can be driven purely by electricity. Alternatively, the motorized vehicle may be a hybrid vehicle. Using the temperature control device, it is possible to control the temperature, i.e., cool (cool) and / or heat (heat) at least one sub-region of the motorized vehicle, particularly at least one sub-region of the interior space of the motorized vehicle. For example, to control the temperature, particularly heat, at least the above sub-region of the motorized vehicle, i.e., at least a sub-region of the interior space, the temperature control device can operate, for example, as a heat pump in heat pump operating mode, and therefore also called a WP. In the above and below, when referring to heating of the internal space, unless otherwise specified, this should be understood as heating at least a portion of the internal space, and as a result, it is conceivable that the entire internal space can be heated. Heating of the internal space is also called heating or warming of the internal space.

[0007] The temperature control device preferably includes a temperature control circulation circuit through which a liquid temperature control medium can flow, and this temperature control circulation circuit is also simply called a temperature control circuit, circuit, or circulation circuit. Preferably, the temperature control medium is a liquid temperature control medium and therefore a liquid. The temperature control medium may include, for example, at least water.

[0008] An ambient air cooling device is installed in the temperature-controlled circulation circuit. The ambient air cooling device can be understood as a heat exchanger, also called a heat transfer device. For example, when a motorized vehicle is running, especially when moving forward, ambient air, and therefore the air surrounding the motorized vehicle, can flow around the heat exchanger. In other words, when a motorized vehicle is running, especially when moving forward, the airflow can flow around the ambient air cooling device, or it does flow, and this airflow is formed by the air surrounding the motorized vehicle. Since the temperature-controlled medium can pass through the ambient air cooling device, heat can be exchanged between the temperature-controlled medium passing through the ambient air cooling device and the air passing through the ambient air cooling device, also called ambient air, so that heat can be transferred from the temperature-controlled medium to the ambient air via the ambient air cooling device. This makes it possible to cool the temperature-controlled medium.

[0009] The temperature-controlled circulation circuit also includes a drive machine that drives a motorized vehicle. Therefore, since the temperature-controlled medium can flow through at least one drive machine, this at least one drive machine can be temperature-controlled using the temperature-controlled medium, i.e., cooled and heated somewhere. This at least one drive machine is also called the first drive machine. In the foregoing and subsequent descriptions, when "at least one drive machine" is mentioned, it should be understood as each first drive machine unless otherwise specified. The drive machine can be formed, for example, as an internal combustion engine, also called a combustion engine. Alternatively, the drive machine can be formed as an electric machine capable of driving a motorized vehicle purely electrically. Preferably, the electric machine is a high-voltage component, and its voltage, in particular the operating voltage or rated voltage, is preferably greater than 50 volts, particularly greater than 60 volts, and very preferably several hundred volts. For example, heat can be selectively transferred from the temperature-regulating medium to the drive machine, or from the drive machine to the temperature-regulating medium, and as a result, the drive machine can be selectively heated or cooled, and an exchange can occur between the drive machine and the temperature-regulating medium flowing through the drive machine. For example, if the temperature-regulating medium has a higher temperature than the drive machine in its path through the drive machine, the temperature-regulating medium is a heating medium capable of heating the drive machine, or functions as a heating medium. For example, if the temperature-regulating medium has a lower temperature than the drive machine in its path through the drive machine, heat can be transferred from the drive machine to the temperature-regulating medium, thereby making it possible to cool the drive machine. The temperature-regulating medium may be, and preferably is, a component of the temperature-regulating device.

[0010] The temperature-controlled circulation circuit also includes an electrical energy storage device, in which electrical energy can or is stored particularly electrochemically. Very preferably, the electrical energy storage device is a high-voltage component, and its voltage, in particular the operating voltage and rated voltage, is preferably greater than 50 volts, particularly greater than 60 volts, and very preferably several hundred volts. For example, the electrical machine described above can be supplied with the electrical energy stored in the energy storage device, thereby enabling the electrical machine to be operated in motor operation, and thus by an electric motor. A motorized vehicle can be driven, for example, electrically, particularly purely electrically, using an electric motor. For example, the electrical energy storage device comprises, for example, a plurality of storage device cells, also simply called cells, that are electrically connected to each other. The storage device cells can store the aforementioned electrical energy particularly electrochemically. The energy storage device is also called a battery, and is a high-voltage battery in particular when the electrical energy storage device is a high-voltage component.

[0011] The temperature-controlled circulation circuit also includes a first heat exchanger, which is provided in addition to the ambient air cooling device. This first heat exchanger is also located in the low-temperature medium circulation circuit through which the low-temperature medium can flow, so that heat can be exchanged between the low-temperature medium and the temperature-controlled medium via the first heat exchanger. The first heat exchanger is, for example, a chiller, or is also called a chiller.

[0012] In particular, the low-temperature medium circulation circuit is provided in addition to the temperature-controlled circulation circuit, and is fluidically separated from the temperature-controlled circulation circuit. Heat can be exchanged between the low-temperature medium and the temperature-controlled medium via the first heat exchanger. In particular, for example, the first heat exchanger for the temperature-controlled medium is a cooling device, or functions as a cooling device, or the first heat exchanger for the temperature-controlled medium is capable of operating as a cooling device, so that heat can be transferred from the temperature-controlled medium to the low-temperature medium via the first heat exchanger. This makes it possible to cool the temperature-controlled medium and heat the low-temperature medium. The low-temperature medium circuit and, by extension, the first heat exchanger, are components of the air conditioning system of a motorized vehicle, which is also called an air conditioner. The air conditioning system is, for example, a compression chiller, or at least capable of operating as a compression chiller. Alternatively, or in addition to the above, the air conditioning system may be capable of operating as a heat pump. In particular, the first heat exchanger for the low-temperature medium may be an evaporator or capable of operating as a first evaporator, and the low-temperature medium can be evaporated using the first evaporator. The low-temperature medium, by evaporation, particularly advantageously receives heat from the temperature-controlled medium, especially via the first heat exchanger, thereby advantageously cooling the temperature-controlled medium, also called the temperature-controlled medium or temperature-controlled fluid.

[0013] For example, a low-temperature medium circulation circuit may include a low-temperature medium heat exchanger in addition to the first heat exchanger, and this low-temperature medium heat exchanger can be positioned particularly downstream of the first heat exchanger in the low-temperature medium circulation circuit.

[0014] In the first modification, air can flow, for example, around and / or through a cryogenic medium heat exchanger, and the air can be introduced into the interior space, i.e., at least a portion of the interior space, and is therefore also called interior space air, interior air, or cabin air. For example, heat can be exchanged between the cryogenic medium and the cabin air via the cryogenic medium heat exchanger, so that heat can be transferred from the cryogenic medium to the cabin air via the cryogenic medium heat exchanger. This cools the cryogenic medium and heats the cabin air, and as the cabin air is introduced into the interior space, the interior space, i.e., at least a portion of the interior space, can be heated and further heated.

[0015] In a second modification, the cryogenic medium heat exchanger can be placed in an internal space circulation circuit, also called an internal circuit, internal circulation circuit, or internal space circuit. A fluid, preferably a liquid, such as a temperature-regulating medium or a fluid different from the temperature-regulating medium, can flow through the internal space circulation circuit. In the second version, heat can be exchanged between the fluid and the cryogenic medium via the cryogenic medium heat exchanger so that heat can be transferred from the cryogenic medium to the fluid via the cryogenic medium heat exchanger. This cools the cryogenic medium and heats the fluid. In this case, the internal space circulation circuit may include an internal space heat exchanger, in particular in addition to the first heat exchanger and in addition to the cryogenic medium heat exchanger, which is also called a heating heat exchanger or can operate as a heating heat exchanger. A fluid can flow through the internal space heat exchanger. In addition, for example, the cabin air that can be introduced into the interior space may flow around the interior space heat exchanger and / or be passable, and heat may be exchanged between the fluid and the cabin air flowing through and / or around the interior space heat exchanger, so that heat can be transferred from the fluid to the cabin air via the interior space heat exchanger. This cools the fluid and heats the cabin air. The cabin air may be introduced into the interior space, or is introduced, so that it can heat the interior space. In particular, for example, the cryogenic medium heat exchanger may be a condenser or may be capable of operating as a condenser, and the cryogenic medium may be cooled using the interior space heat exchanger, and thereby condensed, in particular through the cryogenic medium heat exchanger, so that heat can be transferred from the cryogenic medium to the cabin air or fluid, or by such transfer. In the first and second modified examples, particularly in the heat pump operation described above, the cabin air and thus the internal space can be heated via the first heat exchanger and especially via the low-temperature medium heat exchanger, and the heat pump operation in particular is formed or provided for heating the internal space.

[0016] Furthermore, the temperature-controlled circulation circuit includes a second heat exchanger in addition to the first heat exchanger, which is also provided in the low-temperature medium circulation circuit, and heat can be exchanged between the low-temperature medium and the temperature-controlled medium via this second heat exchanger. In particular, if the above-mentioned internal space heat exchanger is provided, the second heat exchanger is provided in addition to the internal space heat exchanger. The second heat exchanger may be the above-mentioned low-temperature medium heat exchanger, or another heat exchanger provided in addition thereto. Heat can be exchanged between the low-temperature medium and the temperature-controlled medium via the second heat exchanger so that it can be transferred from the low-temperature medium to the temperature-controlled medium, particularly via the low-temperature medium heat exchanger. As a result, the low-temperature medium can be cooled, and the second heat exchanger for the low-temperature medium can be formed as a cooling device or can operate as a cooling device. In particular, since the low-temperature medium can be cooled, for example, using the second heat exchanger, and thereby condensed, the second heat exchanger can be formed as a condenser or can operate as a condenser.

[0017] The temperature control device is equipped with a temperature detection device, which is configured to detect, i.e. measure, a first temperature of the temperature control medium upstream of the ambient air cooling device, a second temperature of the temperature control medium upstream of the drive machine, a third temperature of the temperature control medium upstream of the energy storage device, a fourth temperature around the motorized vehicle, and a fifth temperature of the electrical energy storage device, the fourth temperature also called the ambient temperature or external temperature. For example, the fifth temperature is the temperature of at least one or just one of the storage device cells. Alternatively, the fifth temperature may represent the temperature of the storage device cells of the electrical energy storage device, in particular all of the storage device cells. For example, each temperature detection device is equipped with a temperature sensor for detection.

[0018] The temperature control device also includes an electronic computing device, which is configured to selectively operate the temperature control device in a first heat pump operating mode or a second heat pump operating mode. Preferably, as will be described in more detail later, the electronic computing device is configured to selectively operate the temperature control device in a first heat pump operating mode, a second heat pump operating mode, a third heat pump operating mode, a fourth heat pump operating mode, a fifth heat pump operating mode, or a sixth heat pump operating mode. Since a heat pump operating mode is a different operating mode of a heat pump operating mode, also simply called a mode, in each heat pump operating mode, the temperature control device is capable of operating or is operated as a heat pump to heat and thus heat at least a portion of the motorized vehicle, in particular at least a portion of the interior space of the motorized vehicle. As will be described in more detail later, each heat pump operating mode is also used to temperature control the electrical energy storage device, i.e., to cool and / or heat it, thereby enabling the electrical energy storage device to be maintained in a particularly favorable temperature range and / or at a particularly favorable temperature, thus enabling particularly efficient and effective operation of the electrical energy storage device and, consequently, the motorized vehicle. The ability of the valve device to be switched to different switching states makes it possible to set, i.e., operate, different heat pump operating modes, and at least a portion of the motorized vehicle, and in particular the electrical energy storage device provided in addition to at least a portion of the motorized vehicle, can be temperature-controlled as needed, and thus effectively and efficiently. In particular, since each of the heat pump operating modes, in particular exactly one, belongs to each of the switching states of the valve device, in particular exactly one, by switching the valve device to each switching state, it is possible to set, i.e., operate each heat pump operating mode belonging to each switching state, and as a result, the temperature control device is operational or can be operated in the activated heat pump operating mode.

[0019] A method for operating the temperature control device is also disclosed. In this method, the temperature control device is selectively operated in a first heat pump operating mode, a second heat pump operating mode, a third heat pump operating mode, a fourth heat pump operating mode, a fifth heat pump operating mode, or a sixth heat pump operating mode. This will be explained in detail below.

[0020] The electronic computing unit is configured to operate the temperature control device in a first heat pump operating mode when the first temperature is higher than a predetermined first threshold and the second temperature is higher than a predetermined second threshold. In other words, in this method, the temperature control device operates in a first heat pump operating mode when the first temperature is higher than a predetermined first threshold and the second temperature is higher than a predetermined second threshold. In the first heat pump operating mode, the ambient air cooling device, the drive machine, and the first heat exchanger are flow-technically connected in series with each other, while no flow of the temperature control medium occurs through the energy storage device and the second heat exchanger. This means that in this method, the temperature control medium flows in series, i.e., sequentially, through the ambient air cooling device, the drive machine, and the first heat exchanger in the first heat pump operating mode, while the temperature control medium does not flow through the energy storage device and the second heat exchanger.

[0021] The electronic computing unit is also configured to operate the temperature control device in a second heat pump operating mode when the second temperature is higher than the first threshold, lower than a third threshold that is higher than the first threshold, and higher than the ambient temperature. This means that the third threshold is higher than the first threshold. In other words, in this method, the temperature control device operates in a second heat pump operating mode when the second temperature is higher than the first threshold, lower than the third threshold, and higher than the ambient temperature. In the second heat pump operating mode, the drive machine and the first heat exchanger are flow-technically connected in series with each other, and there is no flow of the temperature control medium through the ambient air cooler, energy storage device, and second heat exchanger. This means that in this method, the temperature control medium flows in series, i.e., sequentially, through the drive machine and the first heat exchanger in the second heat pump operating mode, while the temperature control medium does not flow through the ambient air cooler, energy storage device, and second heat exchanger. For example, the temperature control device includes a valve device arranged in the temperature control circulation circuit, and using this valve device, the ambient air cooler, the drive mechanism, the electrical energy storage device, the first heat exchanger, and the second heat exchanger are interconnected in flow technology, i.e., with respect to the flow of the temperature-controlled medium, so that the temperature control device can selectively operate in either the first or second heat pump operating mode. For this purpose, for example, an electronic computing device can actuate the valve device. The ambient air cooler, the drive mechanism, the electrical energy storage device, the first heat exchanger, and the second heat exchanger are also called elements. Therefore, by actinguating (controlling) the valve device, the elements are interconnected with respect to each flow of the temperature-controlled medium through the elements using the valve device, so that the temperature control device can selectively operate in either the first or second heat pump operating mode. Therefore, the valve device can be configured to set either the first or second heat pump operating mode by connecting its elements. This also applies to the third, fourth, fifth, and sixth heat pump operating modes.

[0022] In one embodiment, to achieve particularly advantageous temperature control, the electronic computing device is configured to operate the temperature control device in a third heat pump operating mode when the third temperature is higher than the fifth temperature and higher than the ambient temperature, and the fifth temperature is lower than a predetermined fourth threshold. In other words, in this method, the temperature control device operates in a third heat pump operating mode when the third temperature is higher than the fifth temperature and higher than the ambient temperature, and when the fifth temperature is lower than the fourth temperature. In the third heat pump operating mode, the drive machine, the energy storage device, and the first heat exchanger are connected in series with flow technology, particularly using a valve device, and in the third heat pump operating mode, there is no flow of the temperature control medium through the ambient air cooling device. This means that in this method, the temperature control medium flows in series through the drive machine and the first heat exchanger in the third heat pump operating mode, while the temperature control medium does not flow through the ambient air cooling device.

[0023] In one embodiment, to achieve particularly advantageous temperature control, the electronic computing device is configured to operate the temperature control device in a fourth heat pump operating mode when the fifth temperature is higher than the fourth temperature, the third temperature is higher than the first temperature, and is lower than the third threshold, and higher than the first threshold, and the second temperature is higher than the second threshold. In other words, in this method, the temperature control device operates in a fourth heat pump operating mode when the fifth temperature is higher than the fourth threshold, the third temperature is higher than the first temperature, and is lower than the third threshold, and higher than the first threshold, and the second temperature is higher than the second threshold.

[0024] In the fourth heat pump operating mode, the ambient air cooling device and the drive machine are connected in series with each other in terms of flow technology, especially using valve devices, and are thus arranged in a first circuit line through which the temperature control medium flows. In the fourth heat pump operating mode, the energy storage device and the first heat exchanger are connected in series with each other in terms of flow technology, especially using valve devices, and are thus arranged in a second circuit line through which the temperature control medium flows and which is fluidly separated from the first circuit line, while there is no flow of the temperature control medium through the second heat exchanger. This means that in this method, the temperature control medium flows in series through the first circuit line, and thus through the ambient air cooling device and the drive machine, in the fourth heat pump operating mode, and the temperature control medium flows in series through the second circuit line, and thus through the energy storage device and the first heat exchanger. The first circuit line and the second circuit line are fluidly separated from each other, and the temperature control medium does not flow through the second heat exchanger.

[0025] In one embodiment, so as to be able to achieve particularly advantageous temperature control, the electronic computing device is configured to operate the temperature control device in a fifth heat pump operating mode when the fifth temperature is higher than the fourth temperature, the third temperature is higher than the first temperature, and is lower than the third threshold value and higher than the first threshold value, and the second temperature is lower than the second threshold value. In other words, in this method, the temperature control device is operated in the fifth heat pump operating mode when the fifth temperature is higher than the fourth threshold value, the third temperature is higher than the first temperature, and is lower than the third threshold value and higher than the first threshold value, and the second temperature is lower than the second threshold value.

[0026] In the fifth heat pump operation mode, the drive machine is arranged in a drive machine line through which the temperature control medium flows, and the energy storage device and the first heat exchanger are connected in series with each other in terms of flow technology, particularly using valve devices, whereby they are arranged in an energy storage device line that is fluidically separated from the drive machine line through which the temperature control medium flows, and there is no flow of the temperature control medium through the ambient air cooling device and the second heat exchanger. This means that in this method, the temperature control medium flows through the drive machine line and thus through the drive machine in the fifth heat pump operation mode, and the temperature control medium flows in series through the energy storage device line and thus through the energy storage device and the first heat exchanger, and the drive machine line and the energy storage device line are fluidically separated from each other. In the fifth heat pump operation mode, the temperature control medium does not flow through the ambient air cooling device and the second heat exchanger.

[0027] In one embodiment, the electronic computing device is configured to operate the temperature control device in a sixth heat pump operation mode when the second temperature is lower than the second threshold value, the third temperature is lower than the third threshold value, and higher than the first threshold value, so as to achieve particularly advantageous temperature control. In other words, in this method, the temperature control device is operated in the sixth heat pump operation mode when the second temperature is higher than the second threshold value, the third temperature is lower than the third threshold value, and higher than the first threshold value.

[0028] In the sixth heat pump operating mode, the drive machine is located in the drive machine line through which the temperature-controlled medium flows, while the second heat exchanger is located in the first heat exchanger line through which the temperature-controlled medium flows, and there is no flow of the temperature-controlled medium through the ambient air cooling device. In the sixth heat pump operating mode, the energy storage device and the first heat exchanger are located in the second heat exchanger line through which the temperature-controlled medium flows and are connected in series with each other, and the second heat exchanger line is fluidically separated from the drive machine line and the first heat exchange line. This means that in this method, in the sixth heat pump operating mode, the temperature-controlled medium flows through the drive machine line, and therefore the drive machine, and at the same time, through the first heat exchanger line, and therefore the second heat exchanger in particular in parallel, and the temperature-controlled medium flows through the second heat exchanger line, and therefore the first heat exchanger, and at the same time, through the energy storage device in particular in parallel, while the temperature-controlled medium does not flow through the ambient air cooling device.

[0029] A second aspect of the present invention relates to a motorized vehicle, also simply called a vehicle, preferably an automobile, and more particularly a passenger car, equipped with a temperature control device according to the first aspect of the present invention. The advantages and favorable configurations of the first aspect of the present invention can be considered as advantages and favorable configurations of the second aspect of the present invention, and vice versa.

[0030] For example, a temperature-controlled circulation circuit includes a first line through which a temperature-controlled medium can flow, and an ambient air cooling device is located in this first line. Since the temperature-controlled medium can flow through the first line and therefore through the ambient air cooling device, heat can be exchanged between the temperature-controlled medium flowing through the ambient air cooling device and the air, also called ambient air, flowing through the ambient air cooling device, so that heat can be transferred from the temperature-controlled medium to the ambient air via the ambient air cooling device. This makes it possible to cool the temperature-controlled medium.

[0031] For example, the temperature-controlled circulation circuit also includes a second line on which a drive machine capable of driving a motorized vehicle is located. Therefore, since the temperature-controlled medium can flow through the second line and thus through at least one drive machine, the at least one drive machine can be temperature-controlled using the temperature-controlled medium, i.e., cooled and heated somewhere. For example, heat can be exchanged between the drive machine and the temperature-controlled medium flowing through the second line and thus through the drive machine, in such a way that heat can be selectively transferred from the temperature-controlled medium to the drive machine, or from the drive machine to the temperature-controlled medium. As a result, the drive machine is selectively heated or cooled. For example, if the temperature-controlled medium has a higher temperature than the drive machine in its path through the second line, the temperature-controlled medium is a heating medium capable of heating the drive machine, or functions as a heating medium. For example, if the temperature-controlled medium has a lower temperature than the drive machine in its path through the second line, heat can be transferred from the drive machine to the temperature-controlled medium, thereby making it possible to cool the drive machine. Preferably, the temperature-controlled medium may be a component of the temperature-controlled device.

[0032] For example, the temperature-controlled circulation circuit also includes a third line through which the temperature-controlled medium can flow, and this third line includes a first branch and a second branch. An electrical energy storage device is located in the first branch. The second branch of the third line is a bypass branch, also called a bypass conduit or detour conduit. The temperature-controlled medium can bypass the first branch and, consequently, the electrical energy storage device via the detour branch. This means that the temperature-controlled medium flowing through the second branch bypasses the first branch and, consequently, the electrical energy storage device, and therefore does not flow through the first branch and, consequently, the electrical energy storage device.

[0033] For example, the temperature-controlled circulation circuit includes a fourth line through which a temperature-controlled medium can flow, and a first heat exchanger is located in this fourth line, in particular in addition to an ambient air cooling device. The first heat exchanger is located in the fourth line, and therefore in the temperature-controlled circulation circuit, and the first heat exchanger is also located in a low-temperature medium circulation circuit through which a low-temperature medium can flow.

[0034] For example, the temperature-controlled circulation circuit includes a fifth line through which the temperature-controlled medium can flow, and a second heat exchanger is provided in addition to the first heat exchanger in this fifth line. The second heat exchanger is also provided in the fifth line, and therefore in the temperature-controlled circulation circuit, and in the low-temperature medium circulation circuit.

[0035] The lines of the temperature-controlled circulation circuit are, for example, each longitudinal region of the temperature-controlled circulation circuit through which the temperature-controlled medium can flow, and in particular, the internal space circulation circuit is provided in addition to the lines of the temperature-controlled circulation circuit. In particular, in the second version, the low-temperature medium heat exchanger may be located in an internal space circulation circuit, also called an internal circuit, internal circulation circuit, or internal space circuit, which is provided in addition to the lines of the temperature-controlled circulation circuit.

[0036] The temperature control device is equipped with a temperature detection device, which is configured to detect, i.e., measure, a first temperature of the temperature control medium in the first line, upstream of the ambient air cooling device. For example, a conveying device is arranged in the temperature control circulation circuit, and the temperature control medium can be conveyed in the flow direction through the temperature control circulation circuit using the conveying device. With respect to the flow direction, i.e., the temperature control medium flowing away from the conveying direction and flowing into the ambient air cooling device, the first temperature of the temperature control medium is the temperature of the temperature control medium generated in the ambient air cooling device downstream of the conveying device and in the first line. The temperature detection device is also configured to detect, i.e., measure, a second temperature of the temperature control medium in the second line, upstream of the drive machine and especially downstream of the conveying device. The temperature detection device is also configured to detect, i.e., measure, a third temperature of the temperature control medium in the third line, upstream of the first branch and upstream of the second branch and especially downstream of the conveying device. This means that the second temperature of the temperature-controlled medium occurs in the fifth line upstream of the drive machine and especially downstream of the conveying device, and the third temperature of the temperature-controlled medium occurs, for example, in the third line upstream of the first branch and upstream of the second branch and downstream of the conveying device. In particular, the terms "upstream" and "downstream" above refer to the temperature-controlled medium flowing in the flow direction, i.e., away from the conveying device and toward the ambient air cooling device or the drive machine, or the temperature-controlled medium flowing through the third line.

[0037] The temperature detection device is also configured to detect, i.e., measure, a fourth temperature around a motorized vehicle, for example. Furthermore, the temperature detection device is configured to detect, for example, a fifth temperature of an electrical energy storage device. For example, a first temperature sensor for detecting a first temperature is located in the first line, upstream of the ambient air cooling device and especially downstream of the conveying device. For example, a second temperature sensor for detecting a second temperature is located in the fifth line, upstream of the drive machine and especially downstream of the conveying device. Also, for example, a third temperature sensor for detecting, i.e., measuring a third temperature is located in the third line, upstream of the first branch and upstream of the second branch and especially downstream of the conveying device. A fourth temperature sensor is, for example, an ambient temperature sensor capable of detecting a fourth temperature, and therefore the ambient temperature. A fifth temperature sensor for detecting a fifth temperature is located, for example, in an electrical energy storage device.

[0038] The temperature control device also includes a valve device that can connect the lines of the temperature control circulation circuit to each other. For this purpose, the valve device can be switched to different switching states, for example, by the operation (control) of the valve device, and in each switching state, the lines are connected to each other using the valve device. In this case, each switching state is different from each other, for example, in their connections of the lines. For example, the valve device can be operated (controlled) electrically or electronically. For example, the valve device is equipped with an electronic computing device, also called a control device, which can, for example, provide an electrical operating signal (control signal). The valve device receives, for example, such a control signal, and thereby the valve device is operated (controlled) or can be operated (controllable). Therefore, the electronic computing device can operate the valve device, and thus can be switched between switching states, and thus can be switched back and forth. In particular, since the valve device is electrically operable, for example, the valve device can be switched between switching states, i.e., switched back and forth, by supplying electrical energy to the valve device.

[0039] The electronic computing unit is configured to operate the temperature control device in a first heat pump operating mode when the first temperature is higher than a predetermined first threshold and the second temperature is higher than a predetermined second threshold. In other words, in this method, the temperature control device operates in a first heat pump operating mode when the first temperature is higher than a predetermined first threshold and the second temperature is higher than a predetermined second threshold. In the first heat pump operating mode, the lines of the temperature control circulation circuit are connected to each other using valve devices so that the first line, the second line and the fourth line are connected in series with flow technology, thereby forming a first overall line through which the temperature control medium flows. This means that in the first heat pump operating mode, the temperature control medium flows through the first overall line, in particular by being transported through the first overall line using a transport device. In the first heat pump operating mode, the lines of the temperature control circulation circuit are connected to each other using temperature control devices so that no flow of temperature control medium occurs through the third line and the fifth line. In other words, for example, the temperature-controlled medium is transported through the first overall line using a conveying device, so the temperature-controlled medium flows through the first overall line, but it does not flow through the third line and the fifth line. This is because it is blocked, for example, by a valve device.

[0040] The electronic computing unit is configured to operate the temperature control device in a second heat pump operating mode when the second temperature is higher than the first threshold, lower than a third threshold that is higher than the first threshold, and higher than the ambient temperature. In other words, in this method, the temperature control device operates in a second heat pump operating mode when the second temperature is higher than the first threshold, lower than the third threshold, and higher than the ambient temperature, and the third threshold is higher (greater) than the first threshold. In the second heat pump operating mode, the lines of the temperature control circulation circuit are connected to each other using valve devices so that the second line and the fourth line are connected in series with flow technology, thereby forming a second overall line through which the temperature control medium flows. This means that in the second heat pump operating mode, for example in this method, the temperature control medium flows through the second overall line by being transported through the second overall line using a transport device. In the second heat pump operating mode, no flow of the temperature-controlled medium occurs through the first line, the third line, and the fifth line. In other words, in this method, and in the second heat pump operating mode, the temperature-controlled medium is transported through the second overall line by the transport device, so that in the second heat pump operating mode, the temperature-controlled medium flows through the second overall line, but does not flow through the first line, the third line, and the fifth line. This is because it is blocked, for example, by a valve device.

[0041] The electronic computing unit is configured to operate the temperature control device in a third heat pump operating mode when the third temperature is higher than the fifth temperature and higher than the ambient temperature, and the fifth temperature is lower than a predetermined fourth threshold. In the third heat pump operating mode, the second line, the third line, and the fourth line are connected in series with each other, thereby forming a third overall line through which the temperature control medium flows. In the third heat pump operating mode, there is no flow of the temperature control medium through the first line and the fifth line. This means that, for example, a conveying device conveys the temperature control medium through the third overall line, causing the temperature control medium to flow through the third overall line, but it does not flow through the first line and the fifth line because it is blocked, for example, by a valve device.

[0042] The electronic computing device is configured such that the temperature control device operates in a fourth heat pump operating mode when the fifth temperature is higher than the fourth threshold, the third temperature is higher than the first temperature, lower than the third threshold, and higher than the first threshold, and the second temperature is higher than the second threshold. In other words, in this method, and especially using the electronic computing device, the temperature control device operates in a fourth heat pump operating mode when the fifth temperature is higher than the fourth threshold, the third temperature is higher than the first temperature, lower than the third threshold, and higher than the first threshold, and the second temperature is higher than the second threshold. In the fourth heat pump operating mode, the lines of the temperature control circulation circuit are connected to each other using valve devices such that the first line and the second line are connected in series with respect to the flow technology, thereby forming a fourth overall line through which the temperature control medium flows. This means that in this method, in the fourth heat pump operating mode, the temperature-controlled medium is transported by flowing through the fourth overall line in the fourth heat pump operating mode, thereby ensuring that the temperature-controlled medium flows through the fourth overall line. In particular, the fourth overall line is the first circuit line described above.

[0043] In the fourth heat pump operating mode, the third and fourth lines form a fifth overall line, which is fluidically separated from the fourth overall line through which the temperature-controlled medium flows. This means that in this method, in the fourth heat pump operating mode, the temperature-controlled medium also flows through the fifth overall line, for example, by being transported through the fifth overall line using a transport device in the fourth heat pump operating mode. However, since the fifth overall line and the fourth overall line are separated from each other using a valve device, the temperature-controlled medium flowing through the fourth overall line does not flow through the fifth overall line, and as a result, the temperature-controlled medium flowing through the fifth overall line does not flow through the fourth overall line. In particular, the fifth overall line is the second circuit line described above.

[0044] In addition, in the fourth heat pump operating mode, each line of the temperature-controlled circulation circuit is connected to each other using valve devices so that no flow occurs through the fifth line in the fourth heat pump operating mode. This means that, for example, the temperature-controlled medium is transported through the fourth and fifth overall lines using a transport device, and thus the temperature-controlled medium flows through the fourth and fifth overall lines in the fourth heat pump operating mode, but the temperature-controlled medium does not flow through the fifth line in the fourth heat pump operating mode because it is blocked, for example, by valve devices.

[0045] Furthermore, the electronic computing device is configured such that the temperature control device operates in a fifth heat pump operating mode when the fifth temperature is higher than the fourth threshold, the third temperature is higher than the first temperature and lower than the third threshold and higher than the first threshold, and the second temperature is lower than the second threshold. In other words, for example, when the fifth temperature is higher than the fourth threshold, the third temperature is higher than the first temperature and lower than the third threshold and higher than the first threshold, and the second temperature is lower than the second threshold, the temperature control device operates in a fifth heat pump operating mode in this method, particularly using the electronic computing device. In the fifth heat pump operating mode, the lines of the temperature control circulation circuit are connected to each other using valve devices such that the second line forms a sixth overall line through which the temperature control medium flows. This means that, in this method, in the fifth heat pump operating mode, for example, the temperature-controlled medium is transported through the sixth overall line using a transport device in the fifth heat pump operating mode, thereby causing the temperature-controlled medium to flow through the sixth overall line and, consequently, the second line. In particular, in the fifth heat pump operating mode, the sixth overall line is the drive machine line described above.

[0046] In the fifth heat pump operating mode, the lines of the temperature-controlled circulation circuit are connected to each other using valve devices such that the third and fourth lines form a seventh overall line through which the temperature-controlled medium flows, which is fluidically separated from the sixth overall line. This means that in this method, in the fifth heat pump operating mode, for example, the temperature-controlled medium is transported by a conveying device through the seventh overall line, thereby flowing through the seventh overall line and consequently the second line. However, since the sixth and seventh overall lines are separated from each other, the temperature-controlled medium flowing through the sixth overall line does not flow through the seventh overall line, and the temperature-controlled medium flowing through the seventh overall line does not flow through the sixth overall line. In addition, in the fifth heat pump operating mode, the lines of the temperature-controlled circulation circuit are connected to each other using temperature-controlled devices so that no flow of temperature-controlled medium occurs through the first and fifth lines. This means that, in particular, the temperature-controlled medium is transported through the sixth and seventh overall lines using a conveying device, and in the fifth heat pump operating mode, the temperature-controlled medium flows through the sixth and seventh overall lines, but does not flow through the first and fifth lines because it is blocked, for example, by a valve device. In particular, in the fifth heat pump operating mode, the seventh overall line is the energy storage device line.

[0047] By switching the valve device between the necessary switching states and thereby activating each heat pump operating mode, for example, the interior space of the motorized vehicle and the electrical energy storage device can be temperature-controlled as needed and therefore particularly advantageously, thereby enabling the energy storage device to be maintained within the steam temperature range. This makes it possible to ensure particularly efficient operation of the motorized vehicle. In particular, the present invention makes it possible to avoid excessively high and excessively low temperatures in the energy storage device, and at the same time, it is possible to avoid undesirable temperatures in the interior space, such as excessively high and excessively low temperatures. This makes it possible to ensure effective and efficient operation of the energy storage device on the one hand, and to obtain or maintain particularly comfortable conditions (environment) in the interior space for the people inside the interior space.

[0048] For example, in the first heat pump operating mode, or in the first heat pump operating mode, the heat provided by the drive machine and the heat from the ambient, in particular through the first heat exchanger and the cryogenic medium heat exchanger, can be used to heat the cabin air and thus the interior space. For example, heat from the electrical energy storage device is not used or is not available for this purpose. In the second heat pump operating mode, or by the second heat pump operating mode, for example with respect to the ambient, drive machine, and electrical energy storage device, only the heat provided by the electrical machine, i.e., waste heat, can be used to heat the cabin air and thus the interior space, in particular through the aforementioned, here particularly, the cryogenic medium heat exchanger. In the third heat pump operating mode, or by the third heat pump operating mode, for example with respect to the ambient and drive machine, only the heat provided by the drive machine, i.e., waste heat, can be used to heat the cabin air and thus the interior space, in particular through the first heat exchanger, in this case particularly through the cryogenic medium heat exchanger, and the remaining heat provided by the drive machine can be used to heat the electrical energy storage device. In the fourth heat pump operating mode, or by the fourth heat pump operating mode, it is possible to use only the heat provided by the electrical energy storage device, i.e., waste heat, with respect to the ambient environment, the drive machinery, and the electrical energy storage device, particularly through the first heat exchanger (chiller) and, for example, a low-temperature medium heat exchanger, to heat the cabin air and thus the interior space, i.e., to warm it. In some cases, the heat provided or available from the drive machinery, i.e., waste heat, can be released to the ambient environment at a lower temperature, for example through the ambient air, thereby making it possible to cool the drive machinery. In the fifth heat pump operating mode, or by the fifth heat pump operating mode, it is possible to use only the heat provided by the electrical energy storage device, therefore waste heat, with respect to the ambient environment, the electrical energy storage device, and the drive machinery, particularly through the first heat exchanger (chiller) and, for example, a low-temperature medium heat exchanger, to heat the cabin air and thus the interior space, i.e., to warm it.In this case, the temperature-controlled medium flowing through the second line and thus the drive machine does not pass through the ambient air cooling device, but is routed around it via a bypass pipeline, also known as a bypass pipeline, which specifically bypasses the ambient air cooling device, thereby ensuring favorable temperature control of the drive machine. The present invention is or provides an advantageous operating strategy, which allows for the efficient temperature control of an electrical energy storage device to bring it to the above temperature range or a favorable temperature, and to maintain it within that temperature range or temperature, while simultaneously ensuring favorable temperature control of the internal space.

[0049] In order to achieve particularly advantageous temperature control, in one embodiment of the present invention, in the third heat pump operating mode, the temperature control medium is configured to flow through the first branch and the second branch is fluidly closed using a valve device. This means that in this method, in the third heat pump operating mode, the temperature control medium flows through the first branch and thus through the energy storage device, but does not flow through the second branch, that is, it does not bypass the electrical energy storage device.

[0050] Another embodiment is characterized in that, in the fourth heat pump operating mode, the temperature-controlled medium flows through the first branch and the second branch is fluidly closed using a valve device, thereby enabling particularly advantageous temperature control.

[0051] In another particularly advantageous embodiment of the present invention, in a fifth heat pump operating mode, the temperature-controlled medium flows through a first branch and the second branch is fluidly closed using a valve device, thereby ensuring particularly advantageous temperature control, especially for electrical energy storage devices.

[0052] In another particularly advantageous embodiment of the present invention, the electronic computing device is configured to operate the temperature control device in a sixth heat pump operating mode when the second temperature is lower than a second threshold, the third temperature is lower than a third threshold, and the temperature is higher than a first threshold. Therefore, for example, in this method, the temperature control device is configured to operate in a sixth heat pump operating mode, particularly using the electronic computing device, when the second temperature is lower than a second threshold, the third temperature is lower than a third threshold, and the temperature is higher than a first threshold. In the sixth heat pump operating mode, the lines of the temperature control circulation circuit are connected to each other using valve devices such that the second line forms an eighth overall line through which the temperature control medium flows. Therefore, for example, in this method, in the sixth heat pump operating mode, the temperature control medium is configured to flow through the eighth overall line and thus the second line in the sixth heat pump operating mode by, for example, the temperature control medium being transported through the eighth overall line using a transport device. In particular, in the sixth heat pump operating mode, the sixth overall line is the drive machinery line described earlier.

[0053] In the sixth heat pump operating mode, each line of the temperature-controlled circulation circuit is connected to the other using temperature-controlled devices so that the temperature-controlled medium flows through the fifth end face side, for example, in this method the temperature-controlled medium is transported by a conveying device through the fifth end face side in the sixth heat pump operating mode. In the sixth heat pump operating mode, the fifth line branches off from the eighth overall line at a branching point, which is located upstream of the drive machine and downstream of the measurement point in the flow direction of the temperature-controlled medium flowing through the eighth overall line. At this measurement point, the second temperature can be detected or is detected, for example, a second temperature sensor is located at the measurement point, particularly in the eighth overall line and thus in the temperature-controlled circulation circuit. In particular, in the eighth heat pump operating mode, the fifth overall line is the first heat exchanger line described above.

[0054] In the sixth heat pump operating mode, the fifth line opens to the eighth overall line at an opening, and this opening is located downstream of the drive mechanism and upstream of the measurement point in the flow direction of the temperature-controlled medium flowing through the eighth overall line. Therefore, since the temperature-controlled medium flowing through the fifth line flows from the branching point to the opening, the opening is located downstream of the branching point in the flow direction of the temperature-controlled medium flowing through the fifth line. In the sixth heat pump operating mode, each line of the temperature-controlled circulation circuit is connected to each other using valve devices so that no flow of temperature-controlled medium occurs through the first line in the sixth heat pump operating mode. In particular, in this method, the temperature-controlled medium is transported by a transport device through the fifth line and the eighth overall line, but in the sixth heat pump operating mode, it does not pass through the first line because it is blocked, for example, by a valve device, so the temperature-controlled medium does pass through the fifth line and the eighth overall line in the sixth heat pump operating mode. In addition, in the sixth heat pump operating mode, the lines of the temperature-controlled circulation circuit are connected to each other using valve devices such that the third and fourth lines form a ninth overall line through which the temperature-controlled medium flows, which is fluidically separated from the eighth overall line and the fifth line. This means that in this method, in the sixth heat pump operating mode, for example, the temperature-controlled medium flows through the ninth overall line by being transported through the ninth overall line using a transport device. In particular, in the sixth heat pump operating mode, the ninth overall line is the second heat exchanger line described above. However, since the ninth overall line is fluidically separated from the eighth overall line and the fifth overall line, particularly by using valve devices, the temperature-controlled medium flowing through the eighth overall line does not flow through the ninth overall line, the temperature-controlled medium flowing through the fifth line does not flow through the ninth overall line, the temperature-controlled medium flowing through the ninth overall line does not flow through the eighth overall line, and the temperature-controlled medium flowing through the ninth overall line does not flow through the fifth line. This makes it possible to ensure particularly advantageous and as-needed temperature control.For example, in the sixth heat pump operating mode, or by the sixth heat pump operating mode, it is possible to utilize only the heat provided from the ambient, or only the heat from the ambient, with respect to the electrical energy storage device, drive machinery, and ambient environment, in order to heat the cabin, particularly the interior space. For this purpose, a second ambient air cooling device is provided in addition to the ambient air cooling device, also called the first ambient air cooling device, which is, for example, located in the fourth line in the sixth heat pump operating mode, or preferably connected in series with the fourth line in flow technology, and is therefore a component of the ninth overall line. The above and subsequent descriptions of the first ambient air cooling device can be readily applied to the second ambient air cooling device, and vice versa. Thus, air can flow to or from the second ambient air cooling device. For example, heat can be transferred from the air or ambient air through the second ambient air cooling device to a temperature-controlled medium flowing through the ninth overall line. Since heat is transferred from the temperature-controlled medium to the low-temperature medium via the first heat exchanger, heat can be transferred from the low-temperature medium to the cabin air, for example, particularly via the low-temperature medium heat exchanger, and possibly via the internal space heat exchanger. In the sixth heat pump operating mode, the temperature-controlled medium flowing through the second line or the eighth overall line and thus the drive machine can surround (circumvent) and thus bypass both the first and second ambient air cooling devices, thereby ensuring favorable temperature control of the drive machine.

[0055] In another embodiment of the present invention, in order to achieve particularly advantageous temperature control, in the sixth heat pump operating mode, the temperature-controlled medium flows through the second branch and the first branch is fluidly closed using a valve device. In particular, in this method, in the sixth heat pump operating mode, the temperature-controlled medium flows through the second branch and therefore bypasses the electrical energy storage device via the second branch and therefore does not flow through the electrical energy storage device. This makes it possible to advantageously temperature control the electrical energy storage device as well.

[0056] In another particularly advantageous embodiment of the present invention, the second line comprises a third branch, in which a drive machine is arranged as a first drive machine. The second line comprises a fourth branch, flow-technically parallel connected to the third branch, in which a second drive machine for driving a motorized vehicle is arranged, in addition to the first drive machine. The above and subsequent descriptions of the first drive machine can be readily applied to the second drive machine, and vice versa. This makes it possible to achieve particularly efficient operation of the motorized vehicle.

[0057] In another configuration of the present invention, to achieve particularly effective, efficient, and on-demand temperature control, an electric heating element for heating the temperature-controlled medium is located in the fourth line. This means that the temperature-controlled medium flowing through the fourth line can be heated using the electric heating element while utilizing the electrical energy supplied to the heating element, thus enabling on-demand temperature control of the temperature-controlled medium in the fourth line. Preferably, with respect to the temperature-controlled medium flowing through the fourth line, away from the conveying device and toward the first heat exchanger, the electric heating element is located downstream of the conveying device and upstream of the first heat exchanger (chiller). This ensures particularly effective and efficient temperature control.

[0058] Finally, it was found to be particularly advantageous if the conveying device includes a first pump for conveying the temperature-controlled medium, located on a second line, and a second pump for conveying the temperature-controlled medium, located on a third line. This makes it possible to achieve effective and efficient temperature control as needed, and preferably, each pump is an electric pump and therefore electrically operable.

[0059] In particular, the present invention makes it possible to achieve the following advantages:

[0060] - Reduction of heat loss compared to conventional solutions - Receiving heat from the surroundings - Increase in storage device temperature or cell temperature due to necessary heat flow direction changes. - Increase in the temperature of the drive mechanism due to the change in the direction of heat flow - In particular, the potential rise in storage device temperature or cell temperature during new startup. - High availability in terms of regenerative and driving performance - Higher efficiency of energy supply through electrical energy storage devices - Avoiding heating (thermal storage) of storage devices by utilizing waste heat from drive machinery. - Electrical energy storage devices, drive mechanisms and utilization of residual ambient heat for heat pumps. - Temperature tracking (temperature monitoring) of an electrical energy storage device via a heat pump operating mode, also known as a heat pump operating type, with the objective of efficiently reaching a temperature range, also called a target range, and maintaining the electrical energy storage device or its temperature within the target range. - Utilization of heat via heat pump operation or drive machinery and electrical energy storage devices, and realization of heat supply through such means. - Heat pump operation and, consequently, electrical energy storage devices, and therefore the utilization of heat through heat dissipation. - A favorable strategy for efficiently redirecting heat flow - For example, there is no need to actively adjust the heating process.

[0061] Further details of the present invention will become apparent from the following description of preferred embodiments with reference to the relevant figures. [Brief explanation of the drawing]

[Figure 7] This is a schematic diagram of the temperature control device, showing the seventh operating mode of the temperature control device. [Modes for carrying out the invention]

[0063] In each figure, identical or functionally identical elements are given the same reference numeral.

[0064] Figure 1 schematically illustrates a temperature control device 1 for a motorized vehicle, also simply called a vehicle, preferably an automobile, particularly a passenger car. Preferably, the temperature control device 1 includes a temperature control circulation circuit 2 through which a liquid temperature control medium, which is a component of the temperature control device 1, can flow. This temperature control circulation circuit is also simply called a temperature control circuit, circuit, or circulation circuit. The temperature control circulation circuit 2 includes a first line S1 through which the temperature control medium can flow, and a first ambient air cooling device 3 is arranged in this first line. Since ambient air, i.e., the air surrounding the motorized vehicle, can flow through the ambient air cooling device 3, it is possible to transfer heat from the temperature control medium to the ambient air via the ambient air cooling device 3. This makes it possible to cool the temperature control medium via the ambient air cooling device 3. The temperature control circulation circuit 2 also includes a second line S2 through which the temperature control medium can flow, and two drive machines 4 and 5 are arranged in this second line, as will be described later. In the embodiments shown in each figure, each drive machine 4, 5 is formed as an electromachine capable of driving a motorized vehicle purely electrically. For example, line S2 has at least one first electrical or electronic component 6, the first component being, for example, power electronics assigned to drive machine 4 in particular.

[0065] The temperature-controlled circulation circuit 2 also includes a third line S3 through which the temperature-controlled medium can flow, and this third line includes a first branch Z1 and a second branch Z2 as peripheral branch sections. An electrical energy storage device 7 is located in the first branch Z1, and this electrical energy storage device is preferably a high-voltage component, and is therefore also called an HVS or high-voltage storage device. Since the temperature-controlled medium can bypass the first branch section via the second branch Z2, the temperature-controlled medium flowing through the second branch Z2 does not pass through the first branch Z1, and therefore does not flow through the electrical energy storage device 1, which is also simply called a storage device or energy storage device. Figure 1 shows that the second line S2 includes a third branch Z3, and a drive machine 4 and, in this case, a component 6 are located in the third branch section. In addition, the second line S2 includes a fourth branch Z4, and a drive machine 5 is located in the fourth branch section. In particular, when the temperature-controlled medium flows through the second line S2 and passes through branch sections Z3 and Z4, branch sections Z3 and Z4 are connected in parallel from a flow perspective.

[0066] The temperature-controlled circulation circuit 2 also includes a fourth line S4, on which a first heat exchanger 8 is located. The first heat exchanger 8 is also called a chiller. The first heat exchanger 8 is also located in a cryogenic medium circulation circuit, which is not shown in each figure, through which a cryogenic medium can flow. This cryogenic medium circulation circuit is preferably located in addition to the temperature-controlled circulation circuit 2, and very preferably is fluidically separated from the temperature-controlled circulation circuit 2. Heat can be exchanged between the cryogenic medium and the temperature-controlled medium via the heat exchanger 8, in particular, so that the heat exchanger 8 functions, is formed, or is operable as a cooling device for the temperature-controlled medium. Thus, for example, heat can be transferred from the temperature-controlled medium to the cryogenic medium via the heat exchanger 8, thereby cooling the temperature-controlled medium and heating the cryogenic medium.

[0067] The temperature-controlled circulation circuit 2 also includes a fifth line S5, on which a second heat exchanger 9 is located. The heat exchanger 9 is also located in a cryogenic medium circulation circuit through which a cryogenic medium can flow. In particular, the second heat exchanger 9 for the cryogenic medium may be formed, function, or be operable as a cooling device, so that, for example, the cryogenic medium can be cooled using the heat exchanger 9. In particular, for example, the heat exchanger 9 may be a condenser or be operable as a condenser, so that the cooling medium can be cooled using the heat exchanger 9, thereby allowing it to condense. Heat can be exchanged between the temperature-controlled medium flowing through line S5 and the cryogenic medium via the heat exchanger 9, in particular so that heat can be transferred from the cryogenic medium to the temperature-controlled medium flowing through line S5. In particular, since the temperature-controlled medium is a liquid, the heat exchanger 9 may be formed, for example, as a liquid-cooled, particularly water-cooled, condenser, which is also called a WCC.

[0068] The temperature control device 1 includes a conveying device 10 located in the temperature control circulation circuit 2, which can be used to convey the temperature control medium through the temperature control circulation circuit, particularly in the flow direction. Preferably, the conveying device 10 is electrically operable. The conveying device 10 will be described in more detail later. Furthermore, the temperature control device 1 includes a temperature detection device 11 located in the temperature control circulation circuit 2, which can be used to detect, i.e., measure, a first temperature of the temperature control medium, also called T3, located upstream of the ambient air cooling device 3 and downstream of the conveying device 10 in the first line S1. For this purpose, for example, the temperature detection device 11 includes a first temperature sensor 12 located at a first measurement point in the temperature control circulation circuit 2, where the first measurement point is located upstream of the ambient air cooling device 3 and particularly downstream of the conveying device 10 in line S1. At the first measurement point, the first temperature (T3) can be measured by the first temperature sensor 12, so the first temperature occurs at the first measurement point, and the first temperature of the temperature-controlled medium in the temperature-controlled circulation circuit 2 is that of the first measurement point. Using the temperature detection device 11, the second temperature of the temperature-controlled medium can be detected, i.e., measured, upstream of the drive machines 4 and 5 in the second line. For this purpose, for example, the temperature detection device 11 includes a second temperature sensor 13 located at the second measurement point in the temperature-controlled circulation circuit 2, particularly in line S2. At the second measurement point, the second temperature sensor 13 can detect, i.e., measure the second temperature, also called T5, and here, the second measurement point and, for example, the second temperature sensor 13, are located upstream of the drive machines 4 and 5 and particularly downstream of the conveying device 10. In the embodiments shown in each figure, the second measurement point and thus the second temperature sensor 13 are positioned upstream of line S5, particularly upstream of the branching point where line S5 branches off from line S2, in the flow direction of the temperature-controlled medium that flows through the second line S2, away from the conveying device 10 and towards each drive machine 4, 5.

[0069] The temperature detection device 11 is capable of detecting, i.e., measuring, the third temperature of the temperature-controlled medium in the third line S3 upstream of the first branch Z1, upstream of the second branch Z2, and downstream of the conveying device 10. For this purpose, the temperature detection device 11 includes, for example, a third temperature sensor 14 located at the third measurement point in the temperature-controlled circulation circuit 2. Therefore, for example, the temperature sensor 14 at the third measurement point can detect the third temperature of the temperature-controlled medium, so the third temperature is the third temperature of the temperature-controlled medium occurring at the third measurement point. Therefore, the second temperature is the second temperature of the temperature-controlled medium occurring at the second measurement point. At this time, the second temperature, the third temperature, and the first temperature are occurring in the temperature-controlled circulation circuit 2. The third measurement point is located upstream of the branch Z1 and Z2 and downstream of the conveying device 10 in the flow direction of the temperature-controlled medium flowing through line S3 and away from the conveying device 10 towards the branch Z1 and Z2. The third temperature is also called T6. The temperature detection device 11 is also capable of detecting the ambient temperature as a fourth temperature. Therefore, the fourth temperature is the temperature around the motorized vehicle. For this purpose, the temperature detection device 11 is equipped with a fourth temperature sensor 15, also called an ambient temperature sensor. The ambient temperature sensor can be used to detect, i.e., measure, the ambient temperature. Finally, the temperature detection device 11 is also capable of detecting, i.e., measuring the temperature of the electrical energy storage device 7, also called Tz. For this purpose, the temperature detection device 11 is equipped with a fifth temperature sensor 16, for example, located in the electrical energy storage device 7. For example, the fifth temperature is or represents the temperature of at least one energy storage cell (battery) of the electrical energy storage device 7.

[0070] The temperature control device 1 here comprises a valve device 17 having two valves 18 and 19. For example, valve 18 is an external component with respect to valve 19, and therefore located outside valve 19, and correspondingly valve 19 is an external component with respect to valve 18, and therefore located outside valve 18. Therefore, preferably valve 18 is provided in addition to valve 19, and preferably valve 19 is provided in addition to valve 18. In particular, valves 18 and 19 are individual components formed completely separately from each other. Each valve 18 and 19, and thus the valve device 17, can be switched between different switching states, in particular by the preferred electrical operation (control) of each valve 18 and 19, and thus the valve device 17. For this purpose, for example, the temperature control device 1 comprises an electronic computing device 20, also called a control device, which can be used to operate (control) each valve 18 and 19, and thus the valve device 17, particularly electrically or electronically. For this purpose, for example, the electronic computing unit 20 can provide electrical operating signals (control signals), and the valves 18 and 19 can receive each operating signal, thereby operating each valve 18 and 19 and thus the valve device 17. As a result, each valve 18 and 19 and thus the valve device 17 can be switched between different switching states, and therefore can be switched back and forth. Each switching state of the valve device 17 can be switched to a different switching state, for example, in order to produce each heat pump operating mode precisely, thereby enabling the setting, i.e., operation of multiple different heat pump operating modes of the temperature control device 1. Therefore, the temperature control device 1 can be operated in different heat pump operating modes using the electronic computing unit 20 and the valve device 17. The temperature control device 1 can operate in heat pump operation, and therefore as a heat pump, and the heat pump operating modes are different operating types or operating modes of the heat pump.

[0071] In particular, the temperature control device 1 is capable of temperature control, i.e., cooling and / or heating, of a motorized vehicle in which the interior space, also called the crew cabin or crew compartment, is formed by, for example, a self-supporting body. In particular, it is possible to particularly favorably temperature control the interior space, the electrical energy storage device 7, and, for example, each drive machine 4, 5 using a heat pump and in each heat pump operating mode. In particular, for example, the interior space can be temperature-controlled so that it can be heated, i.e., warmed. In particular, at the same time, the electrical energy storage device 7 can be favorably temperature-controlled, i.e., cooled and / or heated, so that, for example, the energy storage device 7 can be brought to and / or maintained within a favorable temperature range. It is also possible to avoid unfavorable temperatures for each drive machine 4, 5.

[0072] For example, if the first temperature is greater than a predetermined first threshold and the second temperature is greater than a predetermined second threshold, the temperature control device 1, for example, uses the electronic computing device 20 to switch from one heat pump operating mode to the first heat pump operating mode. If the first temperature is greater than a first threshold and the second temperature is greater than a second threshold, the temperature control device 1, for example, uses the electronic computing device 20 to maintain the first heat pump operating mode. The second threshold is, for example, a target value for the second temperature, and the first threshold is, for example, a target minimum value for the first temperature, which is the outlet temperature of the chiller (first heat exchanger 8). In the first heat pump operating mode, the first line S1, the second line S2, and the fourth line S4 are flow-through and technically connected in series with each other, thereby forming a first overall line G1 through which the temperature-controlled medium flows in the first heat pump operating mode. Lines S1 to S5 of the temperature-controlled circulation circuit 2 are connected to each other using a valve device 17, i.e., valves 18 and 19, so that the temperature-controlled medium does not flow through the third line S3 and the fifth line S5. Figure 1 shows a compensating container indicated by reference numeral 21, which can be used to compensate for volume fluctuations and quantity fluctuations of the temperature-controlled medium in the temperature-controlled circulation circuit 2.

[0073] If the second temperature is higher than the first threshold, lower than a third threshold that is higher than the first threshold, and higher than the ambient temperature, the temperature control device 1 uses the electronic computing device 20 to switch from one of the other heat pump operating modes to the second heat pump operating mode. As long as the second temperature is higher than the first threshold, lower than the third threshold, and higher than the ambient temperature, the temperature control device 1 uses the electronic computing device 20 to operate and maintain in the second heat pump operating mode. The ambient temperature is also called T0. The third threshold is, for example, the target maximum value for the chiller outlet temperature.

[0074] In the second heat pump operating mode shown in Figure 2, lines S1 to S5 of the temperature-controlled circulation circuit 2 are particularly connected to each other in terms of flow technology, such that the second line S2 and the fourth line S4 are connected to each other in series in terms of flow technology, forming a second overall line G2 through which the temperature-controlled medium flows. This allows the temperature-controlled medium to be transported through the second overall line G2 using the transport device 10. In the second heat pump operating mode, the temperature-controlled medium does not flow through the first line S1, the third line S3, and the fifth line S5. In the second heat pump operating mode, it can be seen from Figure 2 that the second overall line G2 is equipped with a bypass pipeline UL, also called a bypass line, and the temperature-controlled medium can or does bypass the ambient air cooling device 3 via the bypass pipeline. This means that in the second heat pump operating mode, the temperature-controlled medium flowing through the second overall line G2 and consequently the bypass pipe UL bypasses the ambient air cooling device 3 via the bypass pipe UL and therefore does not flow through the ambient air cooling device 3. Here, the bypass pipe UL is located downstream of the fourth line S4 and upstream of the second line S2 in the flow direction of the temperature-controlled medium flowing through the overall line G2.

[0075] Figure 3 shows the third heat pump operating mode among the heat pump operating modes. If the third temperature is higher than the fifth temperature and higher than the ambient temperature, and the fifth temperature is lower than a predetermined fourth threshold, which is a different threshold from the first, second, and third thresholds, then, for example, the temperature control device 1 will use the electronic computing device 20 to transition, i.e., switch, from one of the other heat pump operating modes to the third heat pump operating mode. For example, if the third temperature is lower than the third threshold and higher than the first threshold and higher than, for example, the difference value obtained by subtracting a value particularly dependent on the fifth temperature from the fifth temperature, and as a result, for example, the difference value is different from the first, second, third, and fourth thresholds, then, for example, the temperature control device 1 will use the electronic computing device 20 to maintain and operate in the third heat pump operating mode. In the third heat pump operating mode, the lines S1 to S5 of the temperature-controlled circulation circuit 2 are connected to each other using a valve device 17, i.e., valves 18 and 19, so that the second line S2, the third line S3, and the fourth line S4 are technically connected in series with each other, thereby forming a third overall line G3 through which the temperature-controlled medium flows. The temperature-controlled medium flows through the third overall line, for example, by being transported through the third overall line G3 using a transport device 10. In the third heat pump operating mode, the temperature-controlled medium does not flow through the first line S1, the fifth line S5, or, for example, the bypass pipeline UL.

[0076] Figure 4 shows the fourth heat pump operating mode of the temperature control device 1. When the fifth temperature is higher than the fourth threshold, the third temperature is higher than the first temperature and lower than the third threshold and higher than the first threshold, and the second temperature is higher than the second threshold, for example, the temperature control device 1 operates in the fourth heat pump operating mode using the electronic computing device 20. Figure 5 shows the fifth heat pump operating mode of the heat pump operating modes, when the fifth temperature is higher than the fourth threshold, the third temperature is higher than the first temperature and lower than the third threshold and higher than the first threshold, and the second temperature is lower than the second threshold, for example, the electronic computing device 20 operates the temperature control device 1 in the fifth heat pump operating mode. For example, if the fifth temperature is higher than the fourth threshold, in particular if the third temperature is higher than the first temperature, lower than the third threshold, and higher than the first threshold, and the second temperature is higher than the second threshold, then the temperature control device 1 will use the electronic computing device 20 to transition, i.e., switch from one of the other heat pump operating modes to the fourth heat pump operating mode. If the fifth temperature is higher than the fourth threshold, in particular if the third temperature is higher than the first temperature, lower than the third threshold, and higher than the first threshold, and the second temperature is lower than the second threshold, then the temperature control device 1 will use the electronic computing device 20 to transition, i.e., switch from one of the other heat pump operating modes to the fifth heat pump operating mode. If the third temperature is higher than the fifth temperature and higher than the ambient temperature, and the fifth temperature is lower than the fourth threshold, for example, the temperature control device 1 will use the electronic computing device 20 to switch from one of the other heat pump operating modes to the third heat pump operating mode, and as long as the third temperature is higher than the difference value, lower than the third threshold, and higher than the first threshold, the temperature control device 1 will use the electronic computing device 20 to maintain and operate in the third heat pump operating mode.

[0077] As long as the third temperature is higher than the first threshold, lower than the third threshold, and higher than the first threshold, and the second temperature is higher than the second threshold, for example, the temperature control device 1 operates and maintains in the fourth heat pump operating mode using the electronic computing device 20, and this condition is also called the maintenance condition or holding condition. For example, if the fifth temperature is higher than the fourth threshold, but at least one of the above-mentioned maintenance conditions is no longer met, and the fifth temperature is higher than the fourth threshold, for example, the temperature control device 1 switches from the fourth heat pump operating mode to the fifth heat pump operating mode using the electronic computing device 20, and as long as the third temperature is higher than the first temperature, lower than the third threshold, and higher than the first threshold, and the second temperature is lower than the second threshold, for example, the temperature control device 1 operates and maintains in the fifth heat pump operating mode using the electronic computing device 20. The latter condition is also called the second maintenance condition or second holding condition. For example, if the fifth temperature is higher than the fourth threshold, but at least one of the second maintenance conditions is no longer met, the temperature control device 1 may, for example, use the electronic computing device 20 to switch from the fifth heat pump operating mode to the fourth heat pump operating mode, and the temperature control device 1 may, for example, operate and maintain in the fourth heat pump operating mode using the electronic computing device 20, as long as the third temperature is higher than the first temperature, lower than the third threshold, and higher than the first threshold, and the second temperature is higher than the second threshold, or preferably only if the third temperature is higher than the first temperature, lower than the third threshold, and higher than the first threshold, and the second temperature is higher than the second threshold.

[0078] Figure 6 shows the sixth heat pump operating mode among the heat pump operating modes. When the second temperature is lower than the second threshold, the third temperature is lower than the third threshold, and the temperature is higher than the first threshold, for example, the temperature control device 1 operates in the sixth heat pump operating mode using the electronic computing device 20.

[0079] In the fourth heat pump operating mode, the first line S1 and the second line S2 are connected in series with each other, and as can be seen from Figures 4 to 6, the lines S1 to S5 of the temperature-controlled circulation circuit 2 are connected to each other using a valve device 17 so that the temperature-controlled medium is transported through the fourth overall line G4 using the transport device 10 to form the fourth overall line G4 through which the temperature-controlled medium flows. In the fourth heat pump operating mode, the third line S3 and the fourth line S4 are connected in series with each other, and as a result, the temperature-controlled medium is transported through the fifth overall line G5 using the transport device 10 to form the fifth overall line G5 through which the temperature-controlled medium flows. At this time, the overall lines G4 and G5 are fluidically separated from each other using a valve device 17. In the fourth heat pump operating mode, there is no flow of temperature-controlled medium through the fifth line S5, so the temperature-controlled medium does not flow through the fifth line S5.

[0080] In the fifth heat pump operating mode shown in Figure 5, the lines S1 to S5 of the temperature-controlled circulation circuit 2 are connected to each other using a valve device 17, such that the temperature-controlled medium flows through the sixth overall line G6 using the transport device 10, and the first line S2 forms the sixth overall line G6 through which the temperature-controlled medium flows. In the fifth heat pump operating mode, the third line S3 and the fourth line S4 are connected to each other in series, so that the temperature-controlled medium is transported through the seventh overall line G7 using the transport device 10, and the third line S3 and the fourth line S4 form the seventh overall line G7 through which the temperature-controlled medium flows. In the fifth heat pump operating mode, the overall lines G6 and G7 are fluidically separated from each other, particularly using a valve device 17. In addition, in the fifth heat pump operating mode, the temperature-controlled medium is configured not to flow through the first line S1 and the fifth line S5. In the fifth heat pump operating mode, Figure 5 shows that the bypass pipeline UL is a component of the sixth overall line G6, positioned upstream of the conveying device 10 and downstream of line S2, particularly downstream of each drive machine 4, 5, in the flow direction of the temperature-controlled medium flowing through the overall line G6.

[0081] In the optional sixth heat pump operating mode shown in Figure 6, lines S1 to S5 are connected to each other using a valve device 17, such that the second line S2 forms an eighth overall line G8 through which the temperature-controlled medium flows, particularly when the temperature-controlled medium flows through the overall line G8 using a transport device 10. In the sixth heat pump operating mode, the temperature-controlled medium flows through the fifth line S5 and subsequently the heat exchanger 9, for example, so that the temperature-controlled medium is transported through line S5 using the transport device 10. In the sixth heat pump operating mode, the fifth line S5 branches off from the eighth overall line G8 at branching point A1, which is located upstream of the drive machines 4 and 5 and downstream of the second measurement point in the flow direction of the temperature-controlled medium flowing through the overall line G8. At this second measurement point, a second temperature is measured, and for example, a temperature sensor 13 is located there. In the sixth heat pump operating mode, line S5 opens to the eighth overall line G8 at opening M, and opening M is located downstream of the drive machines 4 and 5 and upstream of the second measurement point in the flow direction of the temperature-controlled medium flowing through the overall line G8. In the sixth heat pump operating mode, for example, the temperature-controlled medium bypasses the first line S1 via the bypass pipe UL, which is a component of line S5 and / or the overall line G8 in the sixth heat pump operating mode, so there is no flow of temperature-controlled medium through the first line S1. In the sixth heat pump operating mode, the third line S3 and the fourth line S4 are connected in series with each other, and as a result, the third line S3 and the fourth line S4 form the ninth overall line G9 through which the temperature-controlled medium flows, particularly when the temperature-controlled medium is transported through the overall line using the transport device 10. At this time, the overall lines G8 and G9 are fluidically separated from each other, particularly using the valve device 17.

[0082] According to Figure 6, the temperature control device 1 is equipped with an ambient air heat exchanger 22, which is provided in addition to the ambient air cooling device 3 and in addition to the heat exchangers 8 and 9, and the ambient air can flow through the ambient air heat exchanger. For example, the ambient air heat exchanger 22 is located in an additional line SZ, and in the sixth heat pump operating mode, for example, the additional line SZ and thus the ambient air heat exchanger 22 are components of the overall line G9 such that the additional line SZ is located downstream of the third line S3 and upstream of the fourth line S4 in the flow direction of the temperature control medium flowing through the overall line G9. Heat can be exchanged between the ambient air flowing around and / or through the ambient air heat exchanger 22 and the temperature control medium flowing through the ambient air heat exchanger 22 in the sixth heat pump operating mode, in particular, so that heat can be transferred from the ambient air to the temperature control medium via the ambient air heat exchanger 22. The heat transferred to the temperature-controlled medium via the ambient air heat exchanger 22, and the heat originating from the ambient air, can be supplied to, for example, a chiller (heat exchanger 8), and thus can be used by, for example, the chiller (heat exchanger 8) to temperature-controlled the internal space or the air supplied to the internal space, also known as cabin air. Furthermore, the heat transferred to the temperature-controlled medium via, for example, the ambient air heat exchanger 22, and the heat originating from the ambient air, can be supplied to the internal space and / or heat exchanger 9 via a low-temperature medium circulation circuit in which both the chiller (heat exchanger 8) and heat exchanger 9 are located. In line S4, particularly upstream of heat exchanger 8, an electric heating element 23, formed as, for example, an electric flow heater, is located. Using the electric heating element 23, the electric heating element 23 or the temperature-controlled medium flowing through line S4 can be heated using electric energy. Therefore, for example, in the sixth heat pump operating mode, electric heating can be achieved using the electric heating element 23 so that, for example, the internal space can be particularly advantageously temperature-controlled. The sixth heat pump operating mode is particularly useful when neither the electrical energy storage device 7 nor the drive machines 4 and 5 provide waste heat that can be used to regulate the temperature of the internal space.For example, to realize a heat pump operating mode, the valve device 17 is equipped with a third valve 24 as an additional valve, and the valves 18, 19, and 24 are formed as separate components, particularly located externally to each other, when viewed in pairs.

[0083] For example, heat can be received from the electrical energy storage device 7 using a fifth heat pump operating mode and supplied to the chiller and, via the chiller, to, for example, cabin air or the interior space. This is particularly advantageous when there is excess heat in the energy storage device 7 and therefore the electrical energy storage device 7 can provide heat, particularly waste heat, that can be used for temperature control, especially heating, of the interior space. The fourth heat pump operating mode allows heat to be received from the energy storage device 7 and the chiller and supplied via the chiller to, for example, cabin air and, consequently, the interior space, which is particularly advantageous when there is excess heat in the energy storage device 7. In the third heat pump operating mode, for example, heat can be received from the drive machines 4, 5 and supplied to the chiller and, consequently, cabin air or the interior space, and / or the energy storage device 7 can be heated, in particular, via the chiller. The third heat pump operating mode is particularly advantageous when the energy storage device 7 is at a low temperature and therefore has a low temperature, and there is excess heat in the drive machines 4 and 5, and therefore the drive machines 4 and 5 can use heat, especially waste heat, to heat the internal space and / or the energy storage device 7.

[0084] The second heat pump operating mode allows heat to be taken from the drive machines 4 and 5 and supplied to the chiller and, by extension, to the interior space or cabin air. This is particularly advantageous when the first temperature is higher than the ambient temperature. The first heat pump operating mode allows heat to be taken from or taken from the surroundings, thereby heating the drive machines 4 and 5, for example, and supplying the remaining portion of the heat originating from the surroundings to the chiller, and therefore to the cabin air or interior space via the chiller. This is particularly advantageous when the first temperature is lower than the ambient temperature.

[0085] For example, it can be seen that another electrical or electronic component 25 can be placed in the fifth line S5. This component may be, for example, power electronics assigned to the drive machine 5. In this case, for example, the heat exchanger 9 is located in the fifth branch, and the component 25 is located in the sixth branch of line S5, and the fifth and sixth branches can be connected in parallel to each other in terms of flow technology. For example, it can be seen that an electrically operated fan 26 can be assigned to the ambient air cooler 3 and, for example, the ambient air heat exchanger 22. This makes it possible to use the fan to transport ambient air in order to supply ambient air to the ambient air cooler 3 and the ambient air heat exchanger 22.

[0086] The conveying device 10 includes a first pump 27 located in line S2. In addition, the conveying device 10 includes an additional second pump 28 located in line S3. In each heat pump operating mode, the temperature-controlled medium can be advantageously conveyed through the temperature-controlled circulation circuit 2, for example, using electrically operated pumps 27, 28.

[0087] In each diagram, pipelines through which the temperature-regulating medium does not flow are shown with dashed lines, while pipelines through which the temperature-regulating medium flows are shown with solid lines.

[0088] Figure 7 shows the seventh operating mode of the temperature control device 1, which is preferably the seventh heat pump operating mode. The seventh operating mode shown in Figure 7 essentially corresponds to the fifth heat pump operating mode shown in Figure 5, but differs in the following respects:

[0089] The temperature-controlled circulation circuit 2 is equipped with a connecting pipe 29. In the seventh operating mode, a portion of the temperature-controlled medium flowing through the seventh overall line G7 is branched off from the overall line G7 at the first connection point V1 and introduced into the connecting pipe 29. The first connection point is located between lines S3 and S4 in the flow direction of the temperature-controlled medium flowing through the overall line G7, downstream of the heat exchanger 8 (chiller) and upstream of the branching points Z1 and Z2. The temperature-controlled medium branched off from the overall line G7 and introduced into the connecting pipe 29 flows through the connecting pipe 29 and is guided to the second connection point V2 using the connecting pipe 29. At the second connection point, the temperature-controlled medium flowing through the connecting pipe 29 flows out of the connecting pipe 29 and into the bypass pipe UL, and from the bypass pipe flows into line S2 and then into the sixth overall line G6. Therefore, for example, the connecting pipeline 29 is included in the sixth overall line G6, and thus the sixth overall line is, for example, flow-technically connected in series with S4 and flow-technically connected in parallel with line S3. In other words, line S4 branches into line S3 and overall line G6, which includes the bypass pipeline UL and line S2, and overall line G6 opens to line S4 via the valve device 17, in particular valve 18, and line S3 also opens to line S4. In contrast, for example, in the fifth heat pump operating mode, the sixth overall line G6 and the seventh overall line G7 are flow-technically connected to each other in parallel.
