Description

  The present invention relates to a vehicle air conditioner that performs air conditioning in a passenger compartment of a vehicle.

  The desiccant air conditioning system is a system that performs air conditioning using a desiccant material (desiccant member) that is a dehumidifying agent. FIG. 7 is an explanatory diagram showing a configuration of a desiccant air conditioning system according to a conventional technique. The desiccant air conditioning system 800 according to the prior art is provided with an air introduction passage 810a through which air introduced from the outside passes and an air discharge passage 810b through which air is discharged from the air-conditioned room to the outside.

  The air introduction flow path 810a and the regeneration flow path 810b are provided with a desiccant rotor 801 and a sensible heat exchange rotor 802 in order from the outside. The desiccant rotor 801 and the sensible heat exchange rotor 802 always rotate, and come into contact with the air passing through the air introduction flow path 810a and the air passing through the regeneration flow path 810b alternately.

  The air introduced from the outside by the action of the blower fan 803a comes into contact with the desiccant rotor 801 in the air introduction flow path 810a, and the humidity in the air is removed. The dehumidified air is adjusted to a desired temperature in contact with the sensible heat exchange rotor 802, and supplied to the air-conditioned room as comfortable air.

  On the other hand, the return air from the air-conditioned room is introduced into the regeneration flow path 810b by the action of the blower fan 803b. The return air from the air-conditioned room contacts the sensible heat exchange rotor 802 in the regeneration flow path 810b and exchanges heat with the sensible heat exchange rotor 802. The air subjected to heat exchange is heated by an air heater 803. The air heater 803 can use various exhaust heat or solar heat as a heat source. The air heated by the air heater 803 comes into contact with the desiccant rotor 801 to remove moisture in the desiccant rotor 801 (regeneration of the desiccant rotor), and is discharged to the outdoors.

  For example, Patent Documents 1 and 2 below apply a desiccant air-conditioning system according to the prior art to a vehicle air-conditioner, and are used to introduce air into the vehicle interior and discharge air outside the vehicle. A moisture absorption rotor is rotatably disposed across the regeneration path. The hygroscopic rotor has a hygroscopic material applied to the surface and allows air to pass therethrough. The air introduced into the air introduction path by the first fan is dehumidified when passing through the hygroscopic rotor, and after that, the air is passed through a cooling heat exchanger and a heating heat exchanger, and then brought to an appropriate temperature. be introduced. The air introduced into the regeneration path by the second fan is heated through the heat exchanger for heating, and then deprived of moisture absorbed when passing through the hygroscopic rotor, and then discharged outside the vehicle. The

  As described above, the desiccant air-conditioning system according to the prior art needs to regenerate the desiccant rotor, and thus requires two channels, an air introduction channel and a regeneration channel. Moreover, these two flow paths need to be provided adjacent to each other. For this reason, when the desiccant air conditioning system is applied to a vehicle air conditioner, an air introduction passage for introducing air from the outside of the vehicle into the vehicle and an air discharge passage for discharging air from the inside of the vehicle to the outside of the vehicle are adjacent to each other. It is necessary to provide it.

  However, in order to realize such a structure, there is a problem that the HVAC (Heating, Ventilation, and Air Conditioning) structure of the vehicle becomes complicated and the HVAC structure becomes large. Vehicle space is limited and the introduction of such a large HVAC structure is not practical. Moreover, since the manufacturing cost of a vehicle will increase if the HVAC structure becomes complicated, the application of the desiccant air-conditioning system to a vehicle air-conditioning apparatus becomes impractical.

  The present invention has been made in view of the above-described problems of the prior art, and an object thereof is to provide a vehicle air conditioner to which a desiccant air conditioning system that does not require a regeneration channel is applied.

In order to solve the above-described problems and achieve the object, a vehicle air conditioner according to the invention of claim 1 includes an air introduction flow path for introducing air from an air intake port outside the vehicle and the air after air conditioning into the vehicle interior.

A vehicle air conditioner comprising: a first blower fan that creates an air flow toward the road A location, dehumidification member is provided in the air introduction passage side of said evaporator within said housing in said first flow path, making the flow of air toward the air introduction flow path from the air discharge channel When a second blower fan is provided and the dehumidifying member is to be regenerated, the second blower fan is operated and the flow path switching means switches the air flow path to the first flow path. The air discharge passage is communicated with the vehicle interior, and the air in the vehicle interior introduced from the air discharge passage is discharged from the air intake through the air introduction passage .
According to a second aspect of the present invention, in the vehicle air conditioner, when heating is performed in the vehicle interior, the first blower fan is operated, and the air flow path is changed by the flow path switching means. switching the flow path, when performing cooling in the passenger compartment has a switching benzalkonium the flow path of the air by the channel switching means together to run the first blower fan to the second flow path Features.
The vehicle air conditioner according to a third aspect of the invention is characterized in that the dehumidifying member is regenerated while the vehicle on which the vehicle air conditioner is mounted is stopped.
According to a fourth aspect of the present invention, there is provided a vehicle air conditioner, wherein the vehicle on which the vehicle air conditioner is mounted is an electric vehicle that travels using electric power for at least a part of power, and the regeneration of the dehumidifying member is It is performed during charging of the electric vehicle.
According to a fifth aspect of the present invention, in the vehicle air conditioner, the flow path switching unit includes an air mix damper movably disposed in the housing, and the first flow path and the first flow path The second flow path is formed in the housing by switching the moving position of the air mix damper.

According to the present invention, a vehicle including a channel switching unit that selectively forms a first channel and a second channel in a housing, a heating unit, an evaporator, and a first blower fan. In the air conditioning apparatus for use, a desiccant member is provided on the upstream side of the evaporator, and a second blower fan is provided in the first flow path. Thereby, the air dehumidified by the dehumidifying member can be used for air conditioning, and the air conditioning efficiency of the vehicle air conditioner can be improved.
According to the present invention, the flow path formed by the flow path switching means, the first blower fan, and the second blower fan are changed depending on whether they are in heating, cooling, or regeneration of the dehumidifying member. Switch the operating status. As a result, in the air conditioning system using the dehumidifying member, there is no need to provide a regenerative flow path, and an air conditioning system (desiccant air conditioning system) using the dehumidifying member is also provided for a vehicle air conditioner with a limited installation space. Applicable.
According to the present invention, since the dehumidification member is regenerated (regeneration operation) while the vehicle equipped with the vehicle air conditioner is stopped, the regeneration operation can be performed when the possibility that the user is not on the vehicle is high. In addition, it is possible to reduce the possibility that the desiccant member's dehumidifying ability is lowered and the air conditioning ability is lowered while the vehicle is running.
According to the present invention, when the vehicle equipped with the vehicle air conditioner is an electric vehicle, the regeneration operation is performed while the electric vehicle is being charged. Since there is a high possibility that the vehicle will not be used for the time until the end of charging, it is possible to perform the regeneration operation when there is a high possibility that the user is not on the vehicle, and it is possible to secure a sufficient time for the regeneration operation. Moreover, by performing the regeneration operation while the vehicle is being charged, it is possible to easily secure the electric power necessary for the regeneration operation.
According to the present invention, since the first flow path and the second flow path are formed in the housing by switching the moving position of the air mix damper, the configuration of the conventional air conditioning system of the vehicle is diverted. When the desiccant air conditioning system is applied to a vehicle air conditioner, the degree of change in design or the like can be reduced.

FIG. 2 is an explanatory diagram illustrating a structure of the vehicle air conditioner 100 according to the embodiment.
In the vehicle air conditioner 100 shown in FIG. 2, the configuration other than the desiccant member 104 and the regeneration blower fan 110 is the same as that of the vehicle air conditioner according to the prior art.
The vehicle air conditioner 100 includes a housing H provided between an air introduction flow path 202 for introducing air outside the vehicle and an air discharge flow path 204 for discharging the air after air conditioning into the vehicle interior.
A blower fan 101 is provided at the inlet of the housing H (near the boundary between the housing H and the air introduction flow path 202). The blower fan 101 introduces air outside the vehicle into the vehicle interior via the housing H, and creates an air flow from the air introduction channel 202 toward the air discharge channel 204. More specifically, the blower fan 101 generates air flow from the vehicle exterior direction to the vehicle interior direction in the duct by rotating the wings, and from an air intake port (not shown) provided outside the vehicle. Air is introduced into the housing H. The air introduced into the housing H is further sent toward the passenger compartment along the flow generated by the blower fan 101. The rotation of the blower fan 101 is controlled by, for example, the control means 107 (see FIG. 1).

In the housing H, an air mix damper 103 which is a flow path switching unit is provided. The air mix damper 103 includes a first flow path F1 that communicates the air introduction flow path 202 and the air discharge flow path 204, and a first flow path F1 that communicates the air introduction flow path 202 and the air discharge flow path 204. A second flow path F2 different from the above is selectively formed in the housing H.
That is, in the housing H, the air flow path introduced by the blower fan 101 is led from the air introduction flow path 202 to the air discharge flow path 204 via the heater core 102, and the outside air reaches the vehicle interior. The first flow path F1 and the second flow path F2 that leads the air introduction flow path 202 from the air introduction flow path 202 to the air discharge flow path 204 without passing through the heater core 102 and the outside air to the vehicle interior are formed.
More specifically, the air mix damper 103 is swingable about the support shaft 103X, and is at the first position Sf1 when forming the first flow path F1 as shown in FIG. As shown, the second position Sf2 is set when the second flow path F2 is formed. As an actuator for swinging the air mix damper 103, various conventionally known actuators such as a motor and a solenoid can be used.

  The first flow path F1 is provided with a heater core 102 that is a heating means and a regeneration blower fan 110 that is a second blower fan. The heater core 102 heats air. More specifically, the heater core 102 is circulated with a refrigerant (or cooling water) heated by an engine or a heater. In the heater core 102, the air is heated by supplying heat from the refrigerant to the air passing through the heater core 102 by the action of the blower fan 101. In the present embodiment, the heater core 102 is installed at a substantially central portion of the upper surface of the housing H.

  The regeneration blower fan 110 rotates the wings to generate an air flow in the duct from the vehicle interior direction to the vehicle exterior direction, and an air intake port (not shown) provided from the housing H to the outside of the vehicle. Exhaust air into the air. That is, the regeneration blower fan 110 creates an air flow from the air discharge channel 204 toward the air introduction channel 202. The rotation of the regeneration blower fan 110 is controlled by, for example, the control means 107 (see FIG. 1).

  In addition, an evaporator 105 is provided at the upstream end of the first flow path F1 and the second flow path F2, that is, in the vicinity of the boundary between the housing H and the air introduction flow path 202, and the air introduction flow of the evaporator 105 is A desiccant member 104 is provided on the side of the path 202.

  FIG. 3 is an explanatory view showing the structure of the desiccant member 104. When the air passes through the honeycomb structure S, the desiccant member 104 removes humidity (water vapor) from the air. The humidity removed from the air is accumulated in the desiccant member 104, and the dehumidifying performance of the desiccant member 104 decreases with the passage of the use period. However, when high-temperature air is supplied into the desiccant member 104 during the regeneration operation described later. By removing the humidity accumulated in the desiccant member 104, the dehumidifying performance of the desiccant member 104 is restored. The desiccant member 104 is formed of, for example, a hygroscopic agent such as silica gel or zeolite, and has a honeycomb structure S as shown in FIG.

  Returning to the description of FIG. 2, the evaporator 105 is provided upstream of the air mix damper 103 and dehumidifies the air. More specifically, the evaporator 105 cools the air using the heat of vaporization of the refrigerant and removes water vapor contained in the air. In the present embodiment, the evaporator 105 is provided at the inlet of the housing H, and the air mix damper 103 uses the air flow path dehumidified by the evaporator 105 as the first flow path F1 or the second flow path F2. Switch to one. Note that when the dehumidifying performance of the desiccant member 104 is sufficiently high, the evaporator 105 may not be provided.

  The wind direction adjusting damper 106 (the first wind direction adjusting damper 106a and the second wind direction adjusting damper 106b) discharges air that has undergone heat exchange processing in the housing H from a desired location in the vehicle interior. It is means of. The moving direction of the wind direction adjusting damper 106 is controlled by the control means 107 in accordance with the air conditioning setting by the passenger. In the present embodiment, a first wind direction adjusting damper 106a and a second wind direction adjusting damper 106b are provided in the air discharge channel 204 of the housing H. Further, the air discharge passage 204 of the housing H has a passage 111a (DEF) for supplying deflated air to the periphery of the windshield in the vehicle interior, and air conditioned air near the upper body of the passenger in the vehicle interior. Three flow paths are provided: a flow path 111b (FACE) for supply and a flow path 111c (FOOT) for supplying air-conditioned air near the lower half of the passenger in the passenger compartment.

  When the first wind direction adjusting damper 106a moves to the position Sc1, the supply of conditioned air to the flow path 111a (DEF) is interrupted, and the conditioned air is discharged from the periphery of the windshield in the vehicle interior. Absent. Further, when the first wind direction adjusting damper 106a moves to the position Sc2, the supply of conditioned air to the flow path 111b (FACE) and the flow path 111c (FOOT) is interrupted, and the upper body of the passenger in the passenger compartment Air conditioned air is not discharged near or near the lower body.

  In addition, when the second wind direction adjusting damper 106b moves to the position Se1, the supply of air-conditioned air to the flow path 111b (FACE) is interrupted, and air-conditioned air is placed near the upper body of the passenger in the passenger compartment. There is no discharge. In addition, when the second wind direction adjusting damper 106a moves to the position Se2, the supply of conditioned air to the flow path 111c (FOOT) is interrupted, and air conditioned air is placed near the lower body of the passenger in the passenger compartment. There is no discharge.

  The above-described movable region of the air mix damper 103, the desiccant member 104, and the wind direction adjusting damper 106, the shape of the housing H, and the like are examples, and if the air flow intended by the present invention can be realized, It is not limited to.

The control means 107 (see FIG. 1) controls the operations of the blower fan 101, the heater core 102, the air mix damper 103, the evaporator 105, the wind direction adjusting damper 106, and the regeneration blower fan 110.
The control means 107 includes, for example, a CPU, a ROM that stores and stores a control program, a RAM as an operation area of the control program, an EEPROM that holds various data in a rewritable manner, an interface unit that interfaces with peripheral circuits, and the like. An ECU (not shown) configured to include the control program is executed by the CPU.

  More specifically, the control means 107 operates the blower fan 101 and switches the air flow path to the first flow path F <b> 1 by the air mix damper 103 when heating in the passenger compartment. When cooling in the passenger compartment, the blower fan 101 is operated and the air flow path is switched to the second flow path F2 by the air mix damper 103. Further, when the desiccant member 104 is regenerated, the regeneration blower fan 110 is operated and the air flow path is switched to the first flow path F1 by the air mix damper 103.

  FIG. 4 is an explanatory diagram showing the arrangement of the components of the vehicle air conditioner 100 during heating. When heating is performed in the passenger compartment, the control unit 107 operates the blower fan 101 and switches the air mix damper 103 so that the air flow path is the first flow path F1. That is, the control means 107 positions the air mix damper 103 at the first position Sf1 and sends the air flowing from the outside of the vehicle to the heater core 102 side.

  As a result, the air supplied by the action of the blower fan 101 passes through the vehicle air conditioner 100 in the order of the desiccant member 104, the evaporator 105, and the heater core 102. The air dehumidified by the desiccant member 104 and the evaporator 105 is heated by the heater core 102 and supplied to the passenger compartment as the appropriate temperature air. Note that the evaporator 105 may be turned off during heating.

  FIG. 5 is an explanatory diagram showing the arrangement of the components of the vehicle air conditioner 100 during cooling. When performing cooling in the passenger compartment, the control means 107 operates the blower fan 101 and switches the air mix damper 103 so that the air flow path is the second flow path F2. That is, the control means 107 positions the air mix damper 103 at the second position Sf2 so that the air flowing from the outside of the vehicle is not sent to the heater core 102 side.

  Thereby, the air supplied by the action of the blower fan 101 passes through the vehicle air conditioner 100 in the order of the desiccant member 104 and the evaporator 105. The air that has been dehumidified by the desiccant member 104 and the evaporator 105 and has a low sensible temperature is supplied to the passenger compartment as the appropriate temperature air.

  The arrangement at the time of heating shown in FIG. 4 and the arrangement at the time of cooling shown in FIG. 5 are arrangements when the output of heating or cooling is the highest (so-called MAX_HOT or MAX_COOL). The angle of the air mix damper 103 is controlled according to the output to be performed.

  FIG. 6 is an explanatory diagram showing the arrangement of the components of the vehicle air conditioner 100 during the regeneration operation. As described above, since the desiccant member 104 accumulates the humidity removed from the air, the dehumidifying performance decreases as the usage period elapses. In the regeneration operation, the dehumidifying performance of the desiccant member 104 is recovered by supplying high-temperature air into the desiccant member 104 and depriving the humidity accumulated in the desiccant member 104.

  When performing the regeneration operation, the control means 107 operates the regeneration blower fan 110 and switches the air mix damper 103 so that the air flow path is the first flow path F1. That is, the control means 107 positions the air mix damper 103 at the first position Sf1 and sends the air that has flowed from the inside of the vehicle to the heater core 102 and the desiccant member 104 side.

  Thereby, the air supplied by the action of the regeneration blower fan 110 passes through the vehicle air conditioner 100 in the order of the heater core 102, the evaporator 105, and the desiccant member 104. When the air heated by the heater core 102 passes through the desiccant member 104, the humidity accumulated in the desiccant member 104 is removed, and the dehumidifying performance of the desiccant member 104 is restored.

  The air that has passed through the desiccant member 104 is humid air that contains a large amount of humidity accumulated in the desiccant member 104. The humid air passes through the air introduction channel 202 and is discharged from an air intake (not shown).

  The regeneration (regeneration operation) of the desiccant member 104 is performed, for example, while the vehicle on which the vehicle air conditioner 100 is mounted is stopped. By performing the regeneration operation when the vehicle is stopped, that is, when the user is not on the vehicle, the air conditioning by the vehicle air conditioner 100 can be used constantly while the vehicle is traveling. Further, for example, in a vehicle having a so-called “pick-up air-conditioning function” in which the user designates the vehicle start time in advance and keeps the inside of the vehicle in a desired air-conditioning state by that time, the pick-up air-conditioning function is in operation (or The regeneration operation may be performed before the operation is started. Thereby, reproduction | regeneration driving | operation can be performed in the time slot | zone when the user has not boarded reliably.

  Further, when the vehicle on which the vehicle air conditioner 100 is mounted is an electric vehicle that travels using electric power for at least a part of the power, the regeneration operation may be performed while the electric vehicle is being charged. This is because during charging, there is a high possibility that the vehicle will not be used for the time until the end of charging, and there is a high possibility that sufficient time can be secured for the regeneration operation. Further, if the regeneration operation is performed while the vehicle is being charged, it is possible to easily secure the electric power necessary for the regeneration operation. The regeneration operation may be performed in accordance with the scheduled charging end time.

  As described above, according to the vehicle air conditioner 100 according to the embodiment, the air mix damper 103 that selectively forms the first flow path F1 and the second flow path F2 in the housing H, and the blower In a vehicle air conditioner including a fan 101, a heater core 102, and an evaporator 105, that is, a vehicle air conditioner according to the related art, a desiccant member 104 (dehumidifying member) is disposed upstream of the evaporator 105 with a first flow path. A regeneration blower fan 110 is provided at F1. Thereby, the air dehumidified by the desiccant member 104 can be used for air conditioning, and the air conditioning efficiency of the vehicle air conditioner 100 can be improved.

  Further, according to the vehicle air conditioner 100, the flow path formed by the air mix damper 103, the blower fan 101, and the regeneration fan are changed depending on whether heating, cooling, or regeneration of the desiccant member 104 is in effect. The operating state of the blower fan 110 is switched. As a result, in the air conditioning system using the desiccant member 104, it is not necessary to provide a flow path for regeneration, and an air conditioning system using a dehumidifying member (desiccant air conditioning system) for a vehicle air conditioner having a limited installation space. Can be applied.

  Further, according to the vehicle air conditioner 100, since the dehumidifying member is regenerated (regeneration operation) while the vehicle equipped with the vehicle air conditioner 100 is stopped, it is regenerated when there is a high possibility that the user is not on the vehicle. The driving can be performed, and the possibility that the dehumidifying ability of the desiccant member 104 is lowered during traveling of the vehicle and the air conditioning ability is lowered can be reduced.

  Also, according to the vehicle air conditioner 100, when the vehicle on which the vehicle air conditioner 100 is mounted is an electric vehicle, the regeneration operation is performed while the electric vehicle is being charged. Since there is a high possibility that the vehicle will not be used for the time until the end of charging, it is possible to perform the regeneration operation when there is a high possibility that the user is not on the vehicle, and it is possible to secure a sufficient time for the regeneration operation. Moreover, by performing the regeneration operation while the vehicle is being charged, it is possible to easily secure the electric power necessary for the regeneration operation.

  Further, according to the vehicle air conditioner 100, the first flow path F1 and the second flow path F2 are formed in the housing H by switching the moving position of the air mix damper 103. The configuration of the vehicle air conditioning system can be diverted, and when the desiccant air conditioning system is applied to the vehicle air conditioner, the degree of change in design or the like can be reduced.
