It is experimentally determined in advance so that it can be determined that For example, at the start of the cooling operation, this corresponds to a situation where priority should be given to cooling the passenger compartment.
- step S103 If it is determined in step S103 that the air conditioning heat load LH is lower than the determination heat load LH1, the process proceeds to step S104. On the other hand, if it is determined that the air conditioning heat load LH is greater than or equal to the determination heat load LH1, the process proceeds to step S106.
- step S104 it is determined whether or not the temperature TE of the evaporator 7 serving as a cooler, that is, the evaporator temperature TE is lower than a predetermined cooler temperature determination value TE1.
- the cooler temperature determination value TE1 is experimentally determined in advance so that it can be determined that the evaporator 7 is not sufficiently cooled if the evaporator temperature TE is equal to or higher than the cooler temperature determination value TE1.
- the evaporator 7 may be in a state where it is not sufficiently cooled transiently.
- the cooler temperature determination value TE1 is the same as the target evaporator temperature TEO, which is the target value TEO of the evaporator temperature TE that is sequentially determined in the air conditioning control, or a predetermined allowable temperature difference is added to the target evaporator temperature TEO. Is set to the obtained temperature. That is, since the target evaporator temperature TEO is not a constant value, the cooler temperature determination value TE1 is not a constant value.
- step S104 If it is determined in step S104 that the evaporator temperature TE is lower than the cooler temperature determination value TE1, the process proceeds to step S105. On the other hand, if it is determined that the evaporator temperature TE is equal to or higher than the cooler temperature determination value TE1, the process proceeds to step S106. Accordingly, the outside air introduction control in step S105 is not performed at the start of the cooling operation with a high air conditioning heat load LH or during a transition such as when the evaporator 7 is not sufficiently cooled in the cooling operation.
- step S105 outside air introduction control is performed to control the inside / outside air switching door 13 so that the air conditioning unit 8 enters the outside air introduction mode during the air conditioning operation of the air conditioning unit 8. If the outside air introduction control is already being executed, the outside air introduction control is continuously executed.
- the outside air introduction mode is an operation mode in which the outside air inlet opening RFop is not less than the opening threshold RF1op as described above. Therefore, specifically, the opening threshold RF1op is the lower limit value of the outside air inlet opening RFop in the air conditioning operation of the air conditioning unit 8 performed in parallel with the control processing of FIG. Set as Thereby, in the air conditioning operation, the outside air inlet opening RFop does not become less than the opening threshold RF1op, but the outside air inlet opening RFop is allowed to be equal to or larger than the opening threshold RF1op.
- step S105 the process proceeds to step S108.
- step S106 the outside air introduction control is stopped. In other words, the outside air introduction control is not executed. Thereby, if the opening degree threshold value RF1op has already been set as the lower limit value of the outside air inlet opening degree RFop by the execution of the outside air introduction control in the air conditioning operation of the air conditioning unit 8, the setting of the lower limit value is cancelled. Further, if the outside air introduction control has not already been executed, the outside air introduction control is not executed as it is.
- the inside / outside air switching door 13 may set the outside air inlet opening RFop to be more than the opening threshold RF1op or the opening threshold. It may be less than RF1op. Therefore, the air conditioning unit 8 may perform the air conditioning operation in the outside air introduction mode even when the outside air introduction control is not executed.
- step S107 the same process as in step S106 is performed. After step S106 or step S107, the process proceeds to step S108.
- step S108 it is determined whether the air conditioning operation of the air conditioning unit 8 has been performed in the outside air introduction mode. That is, it is determined whether or not the outside air inlet opening RFop is greater than or equal to the opening threshold RF1op. Since the control process of FIG. 3 is executed during the air conditioning operation of the air conditioning unit 8, the air conditioning operation is being performed when the determination in step S108 is made. Therefore, if the outside air inlet opening RFop is equal to or larger than the opening threshold RF1op, it is determined that the air conditioning operation is performed in the outside air introduction mode.
- step S108 If it is determined in step S108 that the outside air inlet opening RFop is equal to or larger than the opening threshold RF1op, the process proceeds to step S109. On the other hand, if it is determined that the outside air inlet opening RFop is less than the opening threshold RF1op, the process proceeds to step S111. For example, during the execution of the outside air introduction control, the air conditioning operation of the air conditioning unit 8 is performed in the outside air introduction mode, so it is determined that the outside air inlet opening RFop is greater than or equal to the opening threshold RF1op.
- the outside air inlet opening RFop is equal to or larger than the opening threshold RF1op during the air conditioning operation of the air conditioning unit 8
- the outside air inlet opening RFop is equal to or larger than the opening threshold RF1op. Determined.
- step S109 the outside air introduction accumulated time Tfrs is counted, and the outside air introduction accumulated time Tfrs is accumulated. Since the determination in step S108 is performed regardless of whether or not the outside air introduction control is being executed, the outside air introduction cumulative time Tfrs is not only during the time when the outside air introduction control is executed, but also during the non-execution of the outside air introduction control. The time during which the air conditioning operation of the air conditioning unit 8 is performed in the outside air introduction mode is also calculated after being accumulated. The accumulated outside air introduction time Tfrs is calculated in this way because the condensed water is formed on the surface of the evaporator 7 if the air conditioning operation is performed in the outside air introduction mode even when the outside air introduction control is not being executed. Because it can be expected. After step S109, the process proceeds to step S110.
- step S110 the outside air introduction air conditioning time Tfc is counted and the outside air introduction air conditioning time Tfc is accumulated.
- the outside air introduction air conditioning time Tfc is not limited to the time when the outside air introduction control is executed, but the air conditioning operation of the air conditioning unit 8 is not performed during the outside air introduction control. The time performed in is also calculated after being accumulated.
- step S111 the counting of the outdoor air introduction cumulative time Tfrs is stopped. If the outside air introduction cumulative time Tfrs is already stopped, it is continued. After step S111, the process proceeds to step S112. In step S112, the counting of the outside air introduction air conditioning time Tfc is stopped. If the outside air introduction air conditioning time Tfc is already stopped, it is continued.
- step S110 or S112 the process returns to step S101, and the control process of FIG. 3 starts again from step S101.
- the outside air introduction control is executed by executing the control process of FIG. 3, and the outside air is actively taken into the air conditioning case 10 within a range that does not hinder the temperature adjustment in the air conditioning operation of the air conditioning unit 8. Thereby, the amount of condensed water of the evaporator 7 during one trip is increased moderately.
- the air-conditioning control device 61 executes the control process of FIG. 3, but also executes the control process of FIG. That is, the air-conditioning control device 61 changes the flowchart of FIG. 4 on the condition that when the ignition switch 76 of the vehicle is switched from on to off (that is, off), the ignition switch 76 is kept off.
- the control process shown is repeatedly executed periodically.
- FIG. 4 is a flowchart showing a control process related to an outside air blowing control, which will be described later, executed by the adjustment control device 61.
- step S201 in FIG. 4 the air conditioning control device 61 determines whether or not the outside air introduction cumulative time Tfrs is less than the cumulative time threshold value T1. That is, the same determination process as in step S101 in FIG. 3 is performed.
- step S201 If it is determined in step S201 that the outside air introduction cumulative time Tfrs is less than the cumulative time threshold T1, the process proceeds to step S202. On the other hand, if it is determined that the outside air introduction cumulative time Tfrs is equal to or greater than the cumulative time threshold T1, the process proceeds to step S208.
- step S202 it is determined whether or not a predetermined waiting time Twt has elapsed since the ignition switch was switched when the ignition switch 76 was switched from on to off.
- the waiting time Twt is experimentally set in advance so that it can be determined from the elapse of the waiting time Twt that all of the passengers get off after the ignition switch 76 is turned off and the condensed water on the surface of the evaporator 7 falls from the evaporator 7.
- step S202 when it is determined that the waiting time Twt has elapsed since the ignition-off switching, the process proceeds to step S203. On the other hand, if it is determined that the waiting time Twt has not elapsed, the process proceeds to step S209. Therefore, through the determination in step S202, the blower of the blower 16 performed in step S206, which will be described later, is started with a time interval from when the ignition is switched off.
- step S203 it is determined whether or not the odor discharge mode time Tfn, that is, the blowing time Tfn for blowing the blower 16, is less than a predetermined blowing time threshold T3.
- the air blowing time threshold T3 is set to a time that allows the odorous substance trapped in the air conditioning case 10 after the air conditioning operation to be discharged to the outside of the passenger compartment by the air blown by the blower 16, and is set experimentally in advance.
- step S203 If it is determined in step S203 that the blowing time Tfn is less than the blowing time threshold T3, the process proceeds to step S204. On the other hand, if it is determined that the blowing time Tfn is equal to or longer than the blowing time threshold T3, the process proceeds to step S208.
- step S204 the state of the battery that is the power source of the electric device mounted on the vehicle is determined. Specifically, a battery voltage that is a voltage between terminals of the battery is detected, and it is determined whether or not the battery voltage is equal to or higher than a predetermined voltage determination value. If the battery voltage is equal to or higher than the voltage determination value, it is determined that the battery is normal, and if the battery voltage is less than the voltage determination value, it is determined that the battery is abnormal.
- the voltage determination value is a voltage that does not cause a problem even if the electric blower 16 is operated when the ignition switch 76 is off, and is set experimentally in advance.
- step S204 If it is determined in step S204 that the battery voltage is equal to or higher than the voltage determination value, the process proceeds to step S205. On the other hand, if it is determined that the battery voltage is less than the voltage determination value, the process proceeds to step S208.
- step S205 the inside / outside air switching door 13 is caused to open the outside air inlet 12 so that the outside air inlet opening RFop becomes the maximum within the change range of the opening RFop. In short, the outside air inlet 12 is fully opened. If the outside air inlet 12 is already fully open, it is continued. After step S205, the process proceeds to step S206.
- step S206 the blower 16 is blown. That is, the blower 16 is turned on. If the blower 16 is already blowing, the blowing is continued. The amount of air blown at this time is determined in advance to such an extent that, for example, the odorous substance trapped in the air conditioning case 10 can be discharged out of the vehicle.
- the outside air blowing control is performed in which the outside air inlet 12 is opened by the inside / outside air switching door 13 and the blower 16 is blown. As will be described for confirmation, since the evaporator 7 does not cool the air in the blowing by the outside air blowing control, the blowing by the outside air blowing control is not included in the air conditioning operation of the air conditioning unit 8.
- step S207 the process proceeds to step S207.
- step S207 the blowing time Tfn (that is, the odor discharge mode time Tfn) is counted, and the blowing time Tfn is accumulated. Since the blowing time Tfn is zero at the start of blowing of the blower 16 in the outside air blowing control, for example, every time the ignition switch 76 is switched from on to off, it becomes zero, which is an initial value.
- step S208 the blower 16 is stopped and the outside air blowing control is stopped. If the blower 16 is already stopped, it is continued. If the process of step S208 ends, the control process of FIG. 4 ends without being repeated.
- step S209 as in step S208, the blower 16 is stopped and the outside air blowing control is stopped. Then, after step S207 or S209, the process returns to step S201, and the control processing of FIG. 4 starts again from step S201.
- the outside air blowing control is executed by executing the control process of FIG. That is, after a predetermined waiting time Twt has elapsed since the ignition-off switching, the outside air inlet 12 is automatically opened and the blower 16 is driven to ventilate the passenger compartment. As a result, the odorous substance that evaporates after the completion of the air conditioning operation and stays in the air conditioning unit 8 together with the water vapor is discharged out of the passenger compartment.
- steps S105, S106, and S107 correspond to the outside air introduction control unit of the present disclosure
- steps S205, S206, S208, and S209 of FIG. This corresponds to the disclosed outside air blowing section.
- the air conditioning unit 8 when it is determined that the outside air introduction cumulative time Tfrs is less than the cumulative time threshold value T1, the air conditioning unit 8 is performing the air conditioning operation during the air conditioning operation.
- Outside air introduction control is performed to control the inside / outside air switching door 13 so that 8 is in the outside air introduction mode.
- the outside air introduction control is not executed when it is determined that the outside air introduction accumulated time Tfrs is equal to or greater than the accumulated time threshold value T1. Therefore, when odorous substances can be accumulated, it is possible to sufficiently generate condensed water from the outside air by the evaporator 7 and thereby discharge the odorous substances together with the condensed water. For example, odorous substances can be eliminated as usual even in air conditioning in a passenger compartment in a high temperature area.
- step S101 in FIG. 3 and step S201 in FIG. 4 it is determined whether or not the outside air introduction accumulated time Tfrs is less than the accumulated time threshold T1. Therefore, it is possible to prevent the above-described outside air introduction control and outside air blowing control from being performed unnecessarily, and to avoid impairing the air conditioning performance in terms of the temperature adjustment function and the energy saving function of the vehicle air conditioner 100. Is possible. And since the odor reduction effect by the air-conditioning operation in the outside air introduction mode fades with time, the air conditioning performance can be prioritized as much as the odor reduction effect is diminished.
- the air conditioning control device 61 executes the above-described outside air blowing control when the ignition switch 76 is switched from on to off.
- the blower 16 starts blowing air after a time interval from the ignition-off switching time. Therefore, it is possible to automatically ventilate the air conditioning case 10 and the passenger compartment without adjusting the temperature of the air blown from the air conditioning unit 8. As a result, it is possible to eliminate occupant discomfort due to odorous substances. And it is possible to start after the passenger
- the air conditioning control device 61 sucks the outside air into the inside / outside air switching door 13 so that the outside air inlet opening RFop becomes the maximum within the change range of the opening RFop. Open mouth 12. Therefore, the ventilation by the introduction of the outside air is sufficiently performed, and it is possible to shorten the time for continuing the execution of the outside air blowing control for the ventilation.
- the air conditioning control device 61 executes the outside air introduction control on condition that the air conditioning thermal load LH of the air conditioning unit 8 is lower than the determination thermal load LH1. Therefore, in a transitional scene where the air conditioning heat load LH is high, it is possible to cool the air blown from the air conditioning unit 8 so that the immediate effect of cooling is not lost.
- the air conditioning control device 61 executes the outside air introduction control on condition that the evaporator temperature TE is lower than the cooler temperature determination value TE1. Accordingly, it is possible to avoid a decrease in cooling performance due to the execution of the outside air introduction control in a transient situation where the evaporator 7 is not sufficiently cooled, such as at the beginning of the cooling operation.
- the outside air introduction control is executed after the air conditioning heat load LH and the evaporator temperature TE of the air conditioning unit 8 are determined. Therefore, in the air conditioning operation of the air conditioning unit 8, it is possible to positively introduce outside air without hindering the air conditioning performance as much as possible, and to suppress the generation of odor due to the odorous substance on the surface of the evaporator 7.
- the outside air introduction cumulative time Tfrs is not limited to the time when the outside air introduction control is executed, but the air conditioning operation of the air conditioning unit 8 is performed in the outside air introduction mode during the non-execution of the outside air introduction control.
- the time is also calculated after being accumulated. The same applies to the outside air introduction air conditioning time Tfc. Therefore, it is possible to avoid the outside air introduction control from being performed excessively.
- the air conditioning control device 61 performs the outside air introduction operation of the air conditioning unit 8 during the execution of the outside air introduction control from the start to the end of the air conditioning operation of the air conditioning unit 8.
- the outside air introduction air conditioning time Tfc performed in the mode becomes equal to or longer than the air conditioning time determination value T2
- the outside air introduction control is stopped. Therefore, the execution time of the outside air introduction control during one trip is limited, and it is possible to reduce the possibility that the air conditioning performance is deteriorated due to the outside air introduction control being continued.
- the following configuration may be employed to reduce the odor of the air conditioning unit 8.
- a filter that does not allow the passage of odorous substances may be installed in the inside air suction port 11. If it does in this way, it can suppress that an odorous substance mixes in the air which blows in the evaporator 7.

- a catalyst may be provided on the surface of the evaporator 7, and the odorous substance adhering to the evaporator 7 may be changed to an odorless substance by the effect of the catalyst.

- the heater core 34 constitutes a part of the refrigeration cycle 1 and heats the air with the heat of the refrigerant. Is replaced.
- the air conditioning operation of the air conditioning unit 8 is defined as not including a heating operation in which the air is simply heated by the heater core 34 without cooling the air by the evaporator 7. It may be defined that the heating operation is included. However, when it is defined that such a heating operation is included in the air conditioning operation of the air conditioning unit 8, the cumulative time threshold value T1 and the air conditioning time determination value T2 used in the control processing of FIG. Need to be defined.
