Description

  The present invention relates to a control method and a control device for a vehicle air conditioner applied to a vehicle such as a railway vehicle or an automobile.

  Conventionally, in vehicles that run at high speeds such as railway cars and automobiles, natural ventilation is difficult, so the dirty air in the passenger compartment and the fresh air outside the vehicle are separated by forced ventilation using air supply means and exhaust means. A ventilation-integrated air conditioner that replaces the air conditioner and performs air conditioning in the passenger compartment is used.

  As this type of air conditioner, there is an apparatus disclosed in Patent Document 1.

  In the apparatus disclosed in Patent Document 1, the air cycle during normal operation is configured as an open loop. In other words, after using the air compressed in the compressor, cooled in the heat exchanger and expanded in the expander to further reduce the temperature, as a refrigerant for the passenger compartment circulation air, it is blown into the passenger compartment as ventilation air, Dirty air in the passenger compartment is discharged outside the vehicle. Further, in this device, when the vehicle outside pressure fluctuates greatly, such as when vehicles pass each other or when the vehicle passes through a tunnel, the air cycle is switched from the open loop to the closed loop. In other words, after the air cooled at the expander is used as a refrigerant for the passenger compartment circulation air, it is discharged outside the vehicle without being supplied to the passenger compartment, and the passenger compartment circulating air is discharged through the passenger compartment without being discharged outside the vehicle. And circulating. Thus, cooling of the circulating air in the passenger compartment is maintained, and propagation of fluctuations in the external pressure of the passenger compartment to the passenger compartment is suppressed to prevent discomfort felt by passengers.

However, this device switches the air cycle from the open loop to the closed loop when the outside pressure of the vehicle fluctuates greatly, and shuts off fresh air from the atmosphere. Therefore, when the vehicle frequently passes through the tunnel, Insufficient ventilation may cause passenger discomfort. Further, in this apparatus, since the pressure difference between the vehicle interior pressure and the vehicle exterior pressure is to be eliminated due to air leakage from a small gap in the vehicle body, that is, the situation, this differential pressure may not be eliminated. This may hinder the opening and closing of the door.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a system diagram showing an example of an air conditioner including a control device according to the first embodiment of the present invention.

  An air conditioner 1 shown in FIG. 1 is used for ventilation and air conditioning in a passenger compartment 2 of a vehicle that travels at a high speed, such as a railway vehicle or an automobile. The air conditioner 1 includes a dehumidifier 3, a compressor 4, a cooler 5, an expander 6, a circulation fan 7 (first exhaust unit), an exhaust fan 8 (second exhaust unit), which will be described in detail below, and A control device 9 according to the first embodiment is provided.

  The dehumidifier 3 is used for adjusting the humidity of the air supplied into the passenger compartment 2. As such a dehumidifying device 3, for example, a known rotary dehumidifier can be employed. The dehumidifier 3 includes an air supply passage 3a through which air supplied from the atmosphere into the passenger compartment 2 flows, and a discharge passage 3b through which air discharged from the passenger compartment 2 into the atmosphere flows. Although not shown, the dehumidifying device 3 includes a dehumidifying section or a humidifying section (humidifier), and the dehumidifying section and the humidifying section are turned to either the supply passage 3a or the exhaust passage 3b by rotating them. It comes to communicate. In other words, when the dehumidifying part communicates with the air supply passage 3a, the humidifying part communicates with the exhaust passage 3b, and when the humidifying part communicates with the air supply passage 3a, the dehumidifying part communicates with the exhaust passage 3b. As a result, the air taken in from the atmosphere is conditioned.

  A first passage 10 communicating with the atmosphere is connected to the upstream side of the air supply passage 3 a of the dehumidifying device 3. A second passage 11 communicating with the suction side of the compressor 4 is connected to the downstream side of the air supply passage 3a. On the other hand, a third passage 12 communicating with the downstream side of an air refrigerant passage 5b of the cooler 5 described later is connected to the upstream side of the discharge passage 3b. A fourth passage 13 communicating with the atmosphere is connected to the downstream side of the exhaust passage 3b.

  The compressor 4 is for increasing the pressure of the air conditioned by the dehumidifier 3 to a predetermined pressure, and includes a compressor body 4a and a drive device 4b for driving the compressor body 4a. The compressor body 4a includes, for example, two compressor bodies 4c and 4d as shown in FIG. The first-stage compressor body 4c is connected to the drive device 4b, and is driven by the drive device 4b to increase the humidity-controlled air from approximately atmospheric pressure to a predetermined intermediate pressure. The second-stage compressor body 4d is connected to an expander 6 described below, and is driven by the recovery power of the expander 6 to further increase the pressure of the air boosted by the first-stage compressor body 4c. The number of stages is appropriately set according to the discharge pressure of the compressor 4. For example, in the case of one-stage compression, the compressor body 4a, the drive device 4b, and the expander 6 may be connected coaxially. This can simplify the entire facility.

  The cooler 5 is for cooling high-temperature and high-pressure air discharged from the compression device 4. The cooler 5 includes a cooled passage 5a through which high-temperature and high-pressure air flows and an air refrigerant passage 5b through which air refrigerant flows. The high-temperature and high-pressure air is cooled to a predetermined temperature by exchanging heat with the air refrigerant. It is comprised so that.

  A fifth passage 14 connected to the discharge side of the second-stage compressor body 4d is connected to the upstream side of the cooled passage 5a of the cooler 5. A sixth passage 15 communicating with an inlet of an expander 6 described later is connected to the downstream side of the cooled passage 5a. The third passage 12 is connected to the downstream side of the air refrigerant passage 5b. A seventh passage 16 communicating with the atmosphere is connected to the upstream side of the air refrigerant passage 5b. In the middle of the seventh passage 16, the downstream side of the eighth passage 17 through which a part or all of the air discharged from the passenger compartment 2 by the circulation fan 7 described later flows is connected. Thereby, a part or all of the dirty air in the passenger compartment 2 can be discharged into the atmosphere. Further, since the air discharged from the interior of the passenger compartment 2 is merged with the air taken in from the atmosphere, cooling is performed when the air temperature outside the vehicle (atmospheric temperature) is higher than the air temperature inside the vehicle interior (vehicle interior temperature). The temperature of the air supplied to the vessel 5 can be lowered below the atmospheric temperature. As a result, the high-temperature and high-pressure air discharged from the compressor 4 can be efficiently cooled.

  The expander 6 is for expanding the low-temperature and high-pressure air cooled by the cooler 5 to lower the temperature and supplying it to the passenger compartment 2. A ninth passage 18 communicating with the interior of the passenger compartment 2 is connected to the discharge side of the expander 6.

  The circulation fan 7 is for exhausting the air in the passenger compartment 2, and a tenth passage 19 through which the air exhausted from the passenger compartment 2 flows is connected to the suction side. Connected to the discharge side of the circulation fan 7 is an eleventh passage 20 for returning (circulating) a part of the air discharged from the passenger compartment 2 to the first passage 10. This amount of circulating air is appropriately set according to the amount of ventilation from inside the passenger compartment 2. By circulating the air in the passenger compartment 2 as described above, the suction temperature of the compressor 4 can be lowered when the atmospheric temperature is higher than the passenger compartment temperature. As a result, the coefficient of performance (COP) of the air conditioner 1 can be improved. When the atmospheric temperature is lower than the passenger compartment temperature, although not shown, the amount of air flowing through the eleventh passage 20 is adjusted. As a result, the air conditioner 1 can be operated efficiently.

  The exhaust fan 8 is for discharging the dirty air in the passenger compartment 2 into the atmosphere, and for flowing the air refrigerant into the air refrigerant passage 5b of the cooler 5 and discharging it into the atmosphere. Four passages 13 are provided.

  Although the eighth passage 17 is connected to the seventh passage 16 here, the eighth passage 17 may be connected directly to the atmosphere without being connected to the seventh passage 16. In this case, the circulation fan 7 replaces the exhaust fan 8 and discharges dirty air in the passenger compartment 2 to the atmosphere.

  In addition, an external pressure measuring device 21 for measuring an air pressure outside the vehicle (external pressure) P0 is attached to the first passage 10 described above. The vehicle interior 2 includes a vehicle interior temperature measuring device 22 and a vehicle interior pressure measurement for measuring an air temperature (vehicle interior temperature) Tr in the vehicle interior 2 and an air pressure (vehicle interior pressure) Pr in the vehicle interior 2, respectively. A vessel 23 is attached.

  Although not shown, the control device 9 is configured by a computer and includes a central processing unit (CPU), an input / output interface, a computer program and other storage devices such as a RAM and a ROM for storing various information. Prepare. The CPU constitutes calculation means, and the output interface constitutes output means.

  The input interface of the control device 9 is connected to the vehicle exterior pressure measuring device 21, the vehicle interior temperature measuring device 22, and the vehicle interior pressure measuring device 23 so as to communicate with each other. Further, the output interface of the control device 9 is a drive device 4b for the compression device 4, a drive device for the circulation fan 7 and the exhaust fan 8 (in order to control the rotational speeds of the compression device 4, the circulation fan 7 and the exhaust fan 8). Are communicably connected to each other (not shown).

In the control device 9, the target temperature T0 in the vehicle compartment 2 input from an input device (not shown), the external pressure P0, the vehicle interior temperature Tr and the vehicle interior pressure Pr input from the input interface, and other storage devices The operation amounts relating to the rotational speeds of the compressor 4, the circulation fan 7 and the exhaust fan 8 are calculated based on the computer program stored in FIG. Each operation amount is output to the compression device 4, the circulation fan 7 and the exhaust fan 8 through the output interface, and the rotational speeds of the compression device 4, the circulation fan 7 and the exhaust fan 8 are controlled. Thus, the vehicle interior temperature Tr and the vehicle interior pressure Pr are controlled so as to become the target temperature T0 and a target pressure Pt described later. Hereinafter, each control will be described in more detail with reference to FIG.
〔Temperature control〕
As shown in FIG. 2, the first deviation E1 is calculated based on the target temperature Tt in the vehicle interior and the measured vehicle interior temperature Tr. The first deviation E1 is further calculated by the integration element 24, and the calculation result and the first deviation E1 are added. The addition result is multiplied by the first gain K1 of the first proportional element 25, so that the compressor 4 An eleventh operation amount S1 related to the rotation speed is calculated. This process is so-called PI control, but is not limited to this. In the first embodiment, an eleventh correction amount ΔS1 for suppressing interference exerted by the temperature control on the pressure control described later is further calculated by applying a fourteenth operation amount S4 described later to the first transfer function R1. Then, it is added to the eleventh manipulated variable S1 as compensation. Then, information regarding the modified eleventh operation amount S1 ′ is output to the compression device 4. By controlling the rotational speed of the compression device 4 in this way, the temperature in the passenger compartment 2 can be controlled with high accuracy. At the same time, it is possible to suppress the temperature control from interfering with the pressure control described later. The first transfer function R1 is expressed by a mathematical model and is stored in a storage device in advance.

Here, the eleventh operation amount S1 is corrected by the eleventh correction amount ΔS1 to suppress the interference of the temperature control on the pressure control. However, the integration time TI and the first gain K1 of the integration element 24 are appropriately set. By setting, the interference of the temperature control on the pressure control may be suppressed.
(Pressure control)
As shown in FIG. 2, information obtained by applying the filter 26 to information related to the external pressure P0 is set as a target pressure Pt in the vehicle interior. The filter 26 sets a target pressure Pt that gently follows the vehicle external pressure P0. As a result, the target pressure Pr does not change suddenly even when the vehicle outside pressure P0 changes suddenly, and a difference from the vehicle outside pressure P0 does not remain. As a result, pressure control can be performed smoothly. These second deviations E2 are calculated based on the target pressure Pt and the measured vehicle interior pressure Pr. The twelfth manipulated variable S2 is calculated by multiplying the second deviation E2 by the second gain K2 of the second proportional element 27.

  In the first embodiment, the fluctuation amount ΔP of the outside pressure P0 is calculated by applying the outside pressure P0 to the pseudo-differential element 28, and the fluctuation amount ΔP is multiplied by the third gain K3 of the third proportional element 29. Then, a thirteenth operation amount S3 corresponding to the fluctuation amount ΔP is calculated. Then, by subtracting the thirteenth operation S3 from the twelfth operation amount S2, a fourteenth operation amount S4 for suppressing the propagation of pressure fluctuations from the outside of the vehicle into the passenger compartment 2 is calculated.

  Furthermore, in the first embodiment, the twelfth correction amount ΔS41 related to the circulation fan 7 and the eleventh manipulated variable S1 are set to the second transfer function R2 for suppressing the interference of the pressure control on the temperature control. And is added to the fourteenth manipulated variable S4 as compensation. The corrected fourteenth operation amount S41 is added to the reference rotational speed N1 of the circulation fan 7 stored in advance in the storage device. Then, the information regarding the added rotation speed N <b> 1 ′ is output to the circulation fan 7. At the same time, a thirteenth correction amount ΔS42 related to the exhaust fan 8 for suppressing the interference of the pressure control on the temperature control is calculated by giving the eleventh operation amount S1 to the third transfer function R3 as compensation. It adds to said 14th operation amount S4. The corrected fourteenth operation amount S42 is added to the reference rotational speed N2 of the exhaust fan 8 stored in advance in the storage device. Then, the information regarding the added rotation speed N2 'is output to the exhaust fan 8. This control is particularly suitable for devices such as the circulation fan 7 and the exhaust fan 8 that do not greatly change the rotation speed from the reference rotation speed. Of course, the information regarding the modified fourteenth operation amounts S41 and S42 may be directly output to the circulation fan 7 and the exhaust fan 8, respectively. The second and third transfer functions R2 and R3 are expressed by a mathematical model and are stored in a storage device in advance.

  As described above, even when the vehicle outside pressure P0 fluctuates abruptly, such as when vehicles pass each other or when passing through a tunnel, the fluctuation of the vehicle outside pressure P0 is prevented from propagating into the passenger compartment 2. It becomes possible. Thereby, the discomfort which a passenger feels to an ear can be prevented. Moreover, the pressure control in the passenger compartment 2 can be smoothly performed without interfering with the temperature control.

  Here, although the fourteenth operation amount S4 is corrected by the twelfth and thirteenth correction amounts ΔS41 and ΔS42, the interference of the temperature control on the pressure control is suppressed. However, the filter 26 shown in FIG. By appropriately setting the time constant T1, the time constants T2 and TD of the pseudo-differential element 28, the second gain K2 of the second proportional element 27, and the third gain K3 of the third proportional element 29, the pressure control can be You may suppress the interference which acts on control.

Further, when the air exhausted from the circulation fan 7 is not used as the air refrigerant of the cooler 5, the rotational speed of the exhaust fan 8 does not have to be controlled as described above. For example, the exhaust fan 8 may be driven at the reference rotational speed N2. As a result, the control system can be simplified.
(Second Embodiment)
FIG. 3 is a system diagram showing an example of an air conditioner including a control device according to the second embodiment of the present invention.

  As shown in FIG. 3, the air conditioner 30 including the control device according to the second embodiment is a first-stage compressor body as compared to the air conditioner 1 including the control device according to the first embodiment. A bypass passage 31 that connects the passage 4e extending from 4c to the compressor body 4d at the second stage and the ninth passage 18 connected to the discharge side of the expander 6, and the vehicle interior temperature Tr provided in the bypass passage 31 The difference is that a temperature adjusting valve 32 (adjusting means) is further provided. Therefore, parts equivalent to those of the air conditioner 1 including the control device according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In this air conditioner 30, the air taken in from the atmosphere via the dehumidifier 3 is compressed to a predetermined pressure by the first stage compressor body 4a. A part of the high-temperature and high-pressure air is bypassed to the ninth passage 18 on the discharge side of the expander 6 through the bypass passage 31. The amount of air flowing through the bypass passage 31 is adjusted by adjusting the opening degree of the temperature adjustment valve 32. On the other hand, the remaining air is boosted to a predetermined pressure by the compressor body 4d at the second stage, cooled by the cooler 5, expanded by the expander 6, further cooled, and then discharged into the ninth passage 18, Is merged with detoured air. Thereby, air of a predetermined temperature is generated. This air is introduced into the passenger compartment 2. As described above, the temperature in the passenger compartment 2 is controlled.

  In the air conditioner 30, the air introduced into the passenger compartment 2 is discharged from the passenger compartment 2 by the circulation fan 7. A part of the air discharged from the passenger compartment 2 is returned to the first passage 10 connected to the upstream side of the air supply passage 3a of the dehumidifying device 3, and is sucked again into the first-stage compressor body 4c. The remaining air is supplied to the cooler 5 and used as an air refrigerant, and then discharged into the atmosphere by the exhaust fan 8. As a result, the dirty air in the passenger compartment is discharged, and the interior of the passenger compartment 2 can be ventilated. At that time, the rotational speeds of the compressor 4, the circulation fan 7, and the exhaust fan 8 are controlled to adjust the amount of air introduced into the passenger compartment 2 and the amount of air discharged. This makes it possible to control the pressure in the passenger compartment 2.

Specifically, the control device 9 stores the target temperature T0 in the vehicle compartment 2 input from the input device, the vehicle exterior pressure P0, the vehicle interior temperature Tr and the vehicle interior pressure Pr input from the input interface, and other storage devices. Based on the stored computer program and the like, the operation amount relating to the opening degree of the temperature adjustment valve 32 and the operation amount relating to the respective rotational speeds of the compressor 4, the circulation fan 7 and the exhaust fan 8 are calculated. Each manipulated variable is output to the temperature adjustment valve 32, the compression device 4, the circulation fan 7 and the exhaust fan 8 through the output interface, respectively, and the opening degree of the temperature adjustment valve 32 and the compression device 4, the circulation fan 7 and the exhaust fan 8 are output. Control each rotation speed. Thus, the vehicle interior temperature Tr and the vehicle interior pressure Pr are controlled so as to become the target temperature T0 and a target pressure Pt described later. Hereinafter, these controls will be described in more detail with reference to FIG.
〔Temperature control〕
As shown in FIG. 4, in the second embodiment, temperature control is realized by controlling the opening degree of the temperature adjustment valve 32 instead of controlling the rotation speed of the compression device 4. Others are the same as in the first embodiment.
(Pressure control)
As shown in FIG. 4, the pressure control is realized by controlling the rotational speed of the compression device 4 in addition to controlling the rotational speeds of the circulation fan 7 and the exhaust fan 8 described in the first embodiment. doing. Specifically, the 14th correction amount ΔS43 related to the compression device 4 for suppressing the interference of the pressure control on the temperature control is calculated by giving the 11th operation amount S1 to the 4th transfer function R4 as compensation. The value is added to the fourteenth operation amount S4 described in the first embodiment. The corrected fourteenth operation amount S43 is subtracted from the reference rotational speed N3 of the compression device 4 stored in advance in the storage device. Information about the rotational speed N3 ′ is output to the compressor 4. That is, the rotational speed operation of the compressor 4 is added in the opposite phase to the rotational speed operations of the circulation fan 7 and the exhaust fan 8. Thereby, the fluctuation amount of the air supply amount into the passenger compartment 2 is offset with the fluctuation amount of the exhaust amount from the passenger compartment 2. As a result, it is possible to suppress pressure fluctuations in the passenger compartment 2.

As described above, even when the vehicle outside pressure P0 fluctuates abruptly, such as when vehicles pass each other or when passing through a tunnel, the abrupt fluctuation of the vehicle outside pressure P0 is propagated into the passenger compartment 2. It becomes possible to suppress. Thereby, the discomfort which a passenger feels to an ear can be prevented. Moreover, the pressure control in the passenger compartment 2 can be smoothly performed without interfering with the temperature control. The rest is the same as in the first embodiment, and a detailed description thereof will be omitted.

It can be seen that the intake amount) decreases rapidly and greatly, and the vehicle interior pressure Pr decreases and the vehicle interior temperature Tr increases.

Further, it can be seen that the variation in the vehicle interior pressure Pr is considerably smaller than that in the non-control case, and the vehicle interior temperature Tr is hardly changed.
