  According to this Patent Document 1, electric energy is generated based on the circulating heat medium, and the generated electric energy can be effectively utilized by circulating the heat medium using this electric energy. it can. However, since the electric energy generated by circulation of the heat medium is due to the Seebeck effect based on heat transfer to the thermoelectric element, the conversion efficiency of energy conversion between heat energy and electric energy depends on the temperature and flow velocity of the heat medium. May be low.

  According to Patent Document 2, when electric energy is generated exceeding the storage capacity of the battery, the electric energy is converted into heat or cold, the heat is stored in a regenerator, and the cold is stored in cold storage. Can be stored in a container. However, when the conversion efficiency from electric energy to heat energy is low due to the temperature or flow rate of the catalyst, the storage efficiency when storing the electric energy generated exceeding the power storage capacity may be low.

  The present invention has been made paying attention to the above-mentioned problem, and is provided with a plurality of energy conversion devices, and an energy recovery device capable of selecting whether or not to exchange heat with a heat medium for each energy conversion device. Is intended to provide.

  In order to achieve the above object, an invention according to claim 1 is directed to an energy recovery device having a heat accumulator that stores warm heat or a cold accumulator that stores cold heat, through a heat medium stored in the heat accumulator or the cool accumulator and distributed in the flow path.

When, is characterized in that it has a.

  The invention of claim 2 is characterized in that in the invention of claim 1, a control device is provided for outputting a control signal to at least one of the pump and the valve based on environmental information including temperature. is there.

  According to invention of Claim 1, the presence or absence of heat exchange with a thermal energy consumption site | part and a heat medium can be selected. The presence or absence of this heat exchange is determined based on the recovery efficiency of electrical energy or thermal energy at the thermal energy consumption site. Therefore, the energy recovery efficiency is improved when the heat energy of the heat medium is converted into electric energy or recovered as heat energy. As a result, the fuel efficiency of the drive device equipped with this energy recovery device is improved, and drivability is improved.

  According to the second aspect of the present invention, the possibility of circulation at each outlet provided in the valve or the flow rate of the pump is controlled based on environmental information including temperature. Therefore, heat energy of the heat medium can be converted into electric energy, or recovery as heat energy can be controlled based on environmental information including temperature. As a result, the fuel efficiency of the drive device equipped with this energy recovery device is improved, and drivability is improved.

  Next, the present invention will be described in detail based on specific examples. The invention relating to the energy recovery device 1 circulates the heat stored in the regenerator 2 or the cold energy stored in the regenerator 3 through a circulation flow path, and the heat energy of the circulating heat or cold heat medium is converted into electric energy. Alternatively, it is recovered as thermal energy. FIG. 1 schematically shows a flow path through which the heat medium circulates. In FIG. 1, a heat energy consuming part capable of recovering energy as electric energy or heat energy is attached to a flow path 4 for circulating heat or cold. As a specific example corresponding to this thermal energy consumption region, an example in which a thermoelectric generator 5, a heat converter 6, and an air conditioner 7 are attached is described in FIG.

  The thermoelectric generator 5 corresponds to a device that converts thermal energy into electrical energy. As an example, the thermoelectric element corresponds to the thermoelectric generator 5, and at this time, the heat energy of the heat medium circulating in the flow path 4 is converted into electric energy by the Seebeck effect. In the thermoelectric generator 5, the amount of electric energy generated increases as the temperature difference between the thermoelectric generator 5 and the heat medium increases. The heat conversion device 6 corresponds to a device that converts electric energy into heat energy. When the heat conversion device 6 is a thermoelectric element, electric energy is generated by the Peltier effect. And the air conditioner 7 corresponds to the apparatus which collect | recovers heat energy by the heat energy of a heat medium being transmitted. Therefore, even when the temperature difference between the heat medium and the thermoelectric element is small, the heat energy can be effectively recovered if the heat capacity of the heat medium is large.

  Whether heat exchange is possible between the heat medium and the thermoelectric generator 5 or the heat converter 6 or the air conditioner 7 can be controlled. Whether or not this heat exchange is possible is controlled by a valve 8 provided in the flow path 4. This valve determines whether it can be distributed to the flow path 4 to which the thermoelectric generator 5 is attached, whether it can be distributed to the flow path 4 to which the heat conversion apparatus 6 is attached, and whether it can be distributed to the flow path 4 to which the air conditioner 7 is attached. Attached to be selectable. Specifically, there are a switching valve for switching the flow path such as a three-way valve, and an electromagnetic valve for controlling the possibility of flow to the flow path. That is, a valve is attached between the regenerator 2 or the regenerator 3 and the thermoelectric generator 5, and a valve 8 is attached between the thermoelectric generator 5 and the heat converter 6. A valve 8 is attached between the device 7.

  In the present invention, a pump 9 is attached to the flow path 4 in order to circulate the heat medium effectively. This pump 9 is attached in order to improve the circulation efficiency of the heat medium stored in the regenerator 2 or the regenerator 3, and the heat medium circulated from the regenerator 2 or the regenerator 3 is used for the thermoelectric generator 5 or After passing through the heat conversion device 6 and the air conditioner 7, it passes through the pump 9. This heat medium is circulated by the control by pressurization of the pump 9. Specifically, the heat medium is transferred from the thermoelectric generator 5, the heat converter 6, or the air conditioner 7 via the pump 9 to the heat accumulator 2 or It is distributed to the regenerator 3. In other words, the pump 9 is attached to the downstream side of the thermoelectric generator 5, the heat converter 6, and the air conditioner 7 in the circulation of the heat medium.

  In FIG. 2, information on the regenerator 2 or the regenerator 3 is input to the control device 10 mainly composed of a microcomputer, and the control device 10 outputs control instructions to the valve 8 and the pump 9. A schematic diagram is described. The information input to the control device 10 includes an operation request signal 11 and heat storage information 12 or cool storage information 13.

  The operation request signal 11 may be a switch mounted on the vehicle, or may be a signal output from a switch for performing air conditioning. These signals are received based on wireless or wired communication. The heat accumulator information 12 is information on the physical quantity of the heat medium in the case where the heat stored in the heat accumulator 2 is circulated, and specifically corresponds to the heat quantity, temperature, flow rate, and flow velocity. Furthermore, the regenerator information 13 is information about the physical quantity of the heat medium when the cold energy stored in the regenerator 3 is circulated. Specifically, heat quantity, temperature, flow rate, and flow rate are applicable. The regenerator information 12 or the regenerator information 13 is measured by a flow meter, a flow meter, or a thermometer.

  In the control device 10, the control of the valve 8 and the pump 9 having the best energy recovery in the energy recovery device is calculated based on the input operation request signal 11 and the heat storage information 12 or the cool storage information 13. Specifically, the control of the valve 8 is control that allows the valve 8 to be adjusted so that the heat medium can flow through one of the branched flow paths 4. The control of the valve 8 is performed by transmitting an instruction from the control device 10 to the valve 8. Further, the control of the pump 9 can adjust the flow rate of the heat medium flowing through the flow path 4 when adjusting the opening degree of the pump 9. The control of the pump 9 is performed by transmitting an instruction from the control device 10 to the pump 9.

  Regarding the control of the valve 8, in the case of a three-way valve, the heat medium is circulated through the other flow path 4 by closing any one of the two outlets provided. In the case of a solenoid valve, when the valve is open, the heat medium is circulated through the flow path 4 to which the solenoid valve is attached, and when the valve is closed, the heat medium is passed to the flow path 4 to which the solenoid valve is not attached. A heat medium is distributed.

  The flow showing the control relating to the flow of the heat medium in the present invention will be described below. One flowchart is shown in FIG. First, the operation request signal 11 is input to the control device 10 (step S01). Next, the regenerator information 12 or the regenerator information 13 is input to the control device 10 (step S02). Further, based on each information input to the control device 10, the opening / closing of each valve 8 is determined, and the opening / closing of each valve 8 is activated (step S03). And based on each information input into the control apparatus 10, control of the pump 9 attached to the flow path 4 is performed (step S04).

  In FIG. 4, another schematic diagram is described in which information of the regenerator 2 or the regenerator 3 is input to the control device 10 and a control instruction is output from the control device 10 to the pump 9 and the valve 8. . In the control device 10, the control of the pump 9 and the control of the valve 8 are controlled based on the operation request signal 11, the regenerator information 12 or the regenerator information 13, the vehicle travel information 14, and the outside air temperature information 15. . The vehicle travel information 14 includes information such as the moving speed of the driving device such as the vehicle speed, and shift information. The vehicle speed information is measured by a measuring device such as a speedometer, and the shift is measured by providing a sensor around the gear. Is done. The outside air temperature information 15 corresponds to information related to the temperature outside the vehicle. Based on these pieces of information input to the control device 10, the flow rate and flow path control with the best energy recovery in the energy recovery device 1 are calculated. Since the control of the valve 8 and the pump 9 is the same as in FIG. 2 described above, the same reference numerals are given and the description thereof is omitted.

  Another flow showing the control relating to the flow of the heat medium in the present invention will be described below. The one flowchart is shown in FIGS. 5 (a) and 5 (b). First, the operation request signal 11 is input to the control device 10 (steps S11 and S11 '). Next, the travel information 14 is input to the control device 10 (steps S12 and S12 '). Next, the outside air temperature information 15 is input to the control device 10 (steps S13 and S13 '). Next, the regenerator information 12 is input to the control device 10 (step S14) or the regenerator information 13 is input (step S14 ').

  Next, the drive ratio of the pump 9 is calculated based on the information input in steps S11 to S14 or steps S11 'to S14' (steps S15 and S15 '). A map is used to calculate the drive ratio, and this map is input to the control device 10 or the storage device 16 connected so that information can be output to the control device 10. The details of the opening degree α and the correction coefficients β1, β2, γ1, and γ2 used for calculating the drive ratio using this map will be described later. Then, the drive ratio of the pump 9 is obtained based on these correction factors. For example, the drive ratio of the pump 9 is calculated based on a value obtained by multiplying α, β1, and γ1 or α, β2, and γ2. The After the calculation of the drive ratio, the opening / closing of each valve 8 is determined based on the information input to the control device 10 and the calculated pump drive ratio, and the opening / closing of each valve 8 is activated (step S16). , S16 ′). Based on the calculated drive ratio of the pump 9, the control of the pump 9 attached to the flow path 4 is executed (steps S17, S17 ').

  The map used for calculating the drive ratio of the pump 9 will be described below. FIG. 6 shows a map describing the relationship between the opening degree α of the pump 9 and the flow rate flowing through the flow path 4. In this map, the flow rate of the heat medium flowing through the flow path 4 increases as the opening degree α of the pump 9 increases. This is because when the opening degree α of the pump 9 is large, the force for sucking the heat medium flowing through the flow path 4 becomes large.

  FIG. 7 shows a map showing the relationship between the vehicle speed and the opening degree α of the pump 9. In this map, the opening degree α of the pump 9 is constant when the vehicle speed is low. However, when the vehicle speed exceeds a certain value, the opening degree α of the pump 9 increases as the vehicle speed increases. This is because when the vehicle speed is low, the wind received by the energy recovery device 1 is weak, so that the amount of heat released from the heat medium, the thermoelectric generator 5, the heat converter 6, or the air conditioner 7 becomes small. Therefore, by reducing the opening degree α of the pump 9, the electric energy consumed by the pump 9 is reduced, and the heat energy of the heat medium is transmitted to the thermoelectric generator 5, the heat converter 6, or the air conditioner 7. Can do.

  On the other hand, when the vehicle speed is equal to or higher than a certain value, the wind received by the energy recovery device 1 is strong, so that the amount of heat released from the heat medium, the thermoelectric generator 5, the heat converter 6, or the air conditioner 7 increases. Therefore, by increasing the opening degree α of the pump 9, the heat energy radiated from the thermoelectric generator 5, the heat converter 6, or the air conditioner 7 is effectively transmitted from the heat medium. Therefore, when the vehicle speed is equal to or higher than a certain value, the opening degree α of the pump 9 increases as the vehicle speed increases.

  FIG. 8 shows a map of the correction coefficient β1 relating to the drive ratio of the pump 9 when the heat medium stored in the heat accumulator 2 is circulated. When the heat medium stored in the heat accumulator 2 is flowing through the flow path 4, the correction coefficient β1 related to the drive ratio of the pump 9 increases as the outside air temperature decreases. This is because, as the outside air temperature decreases, the energy used for heating or thermoelectric power generation due to a temperature difference from the outside air increases, so that it is necessary to receive more heat energy from the heat medium stored in the regenerator 2. Because. When the outside air temperature is equal to or higher than a certain value, heating is not used, so that the correction coefficient β1 is controlled so that the pump 9 is kept constant at a low driving rate.

  In FIG. 9, the map about the correction coefficient (beta) 2 regarding the drive ratio of the pump 9 when circulating the heat medium stored in the cool storage 3 is described. When the heat medium stored in the regenerator 3 is flowing through the flow path 4, the correction coefficient β2 related to the drive ratio of the pump 9 increases as the outside air temperature increases. This is because the energy used for thermoelectric power generation due to a temperature difference from the cooling or the outside air increases as the outside air temperature increases, so that the driving rate of the pump 9 is increased to increase the heat medium stored in the regenerator 3. This is because it is necessary to receive more heat energy. Further, when the outside air temperature is below a certain value, the cooling is not used, so that the correction coefficient β2 is controlled so that the pump 9 is kept constant at a low driving rate.

  In FIG. 10, the map about the correction coefficient (gamma) 1 regarding the drive ratio of the pump 9 when circulating the heat medium stored in the heat accumulator 2 is described. When the heat medium stored in the heat accumulator 2 flows through the flow path 4, the correction value γ1 related to the pump drive ratio increases as the heat storage air temperature, that is, the temperature of the heat medium decreases. This is because the temperature difference between the heat medium and the thermoelectric generator 5, the heat converter 6, or the air conditioner 7 is reduced, so that the heat medium and the thermoelectric generator are increased by increasing the flow rate of the heat medium flowing through the flow path 4. This is because it becomes necessary to exchange heat with the heat converter 5 or the air conditioner 7.

  Further, when the temperature of the heat accumulator is equal to or higher than a certain value, heat exchange is performed between the heat medium flowing through the flow path 4 and the thermoelectric generator 5, the heat converter 6, or the air conditioner 7, and the heat medium A thermal equilibrium state is established with the thermoelectric generator 5, the heat converter 6, or the air conditioner 7. Therefore, when the heat medium temperature is equal to or higher than a certain value, the correction coefficient γ1 is controlled such that the pump 9 is kept constant at a low driving rate and the power consumption of the pump is minimized.

  In FIG. 11, the map about the correction coefficient (gamma) 2 regarding the drive ratio of the pump 9 when circulating the heat medium stored in the cool storage 3 is described. When the heat medium stored in the regenerator 3 is flowing through the flow path 4, the correction value γ2 related to the drive ratio of the pump 9 increases as the regenerator temperature, that is, the temperature of the heat medium increases. This is because the temperature difference between the heat medium and the thermoelectric generator 5, the heat converter 6, or the air conditioner 7 is reduced, so that the heat medium and the thermoelectric generator are increased by increasing the flow rate of the heat medium flowing through the flow path 4. This is because heat exchange is performed with 5 or the heat conversion device 6 or the air conditioner 7.

  When the regenerator temperature is below a certain value, heat exchange between the heat medium flowing through the flow path 4 and the thermoelectric generator 5, the heat converter 6, or the air conditioner 7 is effectively executed, A thermal equilibrium state is established between the medium and the thermoelectric generator 5, the heat converter 6, or the air conditioner 7. Therefore, when the heat medium temperature is equal to or lower than a certain value, the correction coefficient γ2 is controlled so that the power consumption of the pump is minimized while keeping the driving rate of the pump 9 low.

  In FIG. 12, another schematic diagram is described in which information on the regenerator 2 or the regenerator 3 is input to the control device 10, and instructions regarding the control of the valve 8 and the pump 9 are output from the control device 10. Yes. In the control device 10, the valve 8 and the pump 9 are controlled based on the operation request signal 11, the regenerator information 12 or the regenerator information 13, the vehicle travel information 14, the outside air temperature information 15, and the environment information 17. .

  Environmental information 17 includes traffic jams, under construction, snow cover, landslides, river flooding, closed roads, falling rocks, fallen trees, vehicles stopped at intersections, presence of people and animals, traffic lights at nearby intersections (red, Yellow, blue, etc.), front crossing traffic lights and circuit breaker operating states, time until the display of these traffic lights or circuit breaker switching status, weather, amount of sunlight, wind speed, etc. This environmental information 17 is detected by a sensor corresponding to each information. Based on these pieces of information input to the control device 10, the flow rate and the flow path 4 with the best energy recovery in the energy recovery device 1 are calculated. Since the adjustment of the valve 8 and the pump 9 is the same as that in FIG. 2 described above, the same reference numerals are given and the description thereof is omitted.

  Next, the drive ratio of the pump 9 is calculated based on the information input in steps S21 to S25 or steps S21 'to S25' (steps S26 and S26 '). For this calculation, a map input to the control device 10 or the storage device 16 connected so as to be able to output information to the control device 10 is used. Steps S27 and S27 'and steps S28 and S28' are the same as the above-described steps S16 and S17, and therefore, the description thereof will be omitted by adding the reference numerals.

  In FIG. 14, another schematic diagram is described in which information on the heat storage device 2 or the cold storage device 3 is input to the control device 10 and an instruction for controlling the valve 8 or the pump 9 is output from the control device 10. .
