  The present invention relates to an air conditioner mounted on a vehicle such as an automobile, and particularly relates to a technical field of a structure in which a plurality of air conditioning zones in a vehicle compartment can be individually air conditioned.

  2. Description of the Related Art Conventionally, as this type of vehicle air conditioner, for example, one configured to individually air-condition a driver's seat zone and a passenger seat zone in a vehicle interior of an automobile is known (see, for example, Patent Document 1). . In the casing of the vehicle air conditioner, a blower fan, a cooling heat exchanger, and a heating heat exchanger are arranged in this order from the upstream side of the air flow. The air flow downstream side of the cooling heat exchanger in the casing is divided into a driver seat side passage through which the conditioned air supplied to the driver seat zone flows and a passenger seat side passage through which the conditioned air supplied to the passenger seat zone flows. ing. A driver seat air mix door and a passenger seat air mix door as temperature adjusting means are respectively disposed downstream of the driver seat side passage and the passenger seat side passage in the casing.

  However, in the case of individually air-conditioning the driver's seat zone and the passenger's seat zone as in Patent Document 1, the temperature of the conditioned air supplied from the driver's seat side passage and the passenger seat side passage is appropriate. In addition, there is a demand for individually detecting the air-conditioning state of the driver's seat zone and the passenger seat zone during air-conditioning. In response to this requirement, it is conceivable to provide an inside air temperature sensor in each of the driver's seat zone and the passenger seat zone. However, in this case, the number of parts increases as the number of inside air temperature sensors becomes two and the number of parts increases. The number of man-hours increases and the cost of the air conditioner increases.

  The present invention has been made in view of such a point, and the object of the present invention is to make it possible to estimate the temperature of the air-conditioning zone that does not have the inside air temperature detection means, while avoiding an increase in the number of parts. The object is to make it possible to appropriately determine the temperature of the conditioned air supplied to each zone and to realize comfortable air conditioning in each zone.

  In order to achieve the above object, according to the first aspect of the present invention, the first heat quantity supplied to the first air conditioning zone, the second heat quantity supplied to the second air conditioning zone, and the air in the first air conditioning zone detected by the inside air temperature detecting means. The temperature of the second air-conditioning zone was estimated using this temperature.

Specifically, a casing provided with a first passage and a second passage for supplying conditioned air to each of the first air-conditioning zone and the second air-conditioning zone in the vehicle interior, the casing provided with the first passage, First temperature adjusting means and second temperature adjusting means for adjusting the temperature of the conditioned air flowing through the second passage, first temperature setting means for the occupant to set the temperature of the first air conditioning zone, and Supplyed to the first air-conditioning zone by second temperature setting means for setting the temperature of the second air-conditioning zone, the inside air temperature detecting means arranged in the first air-conditioning zone, and the conditioned air blown out from the first passage. Based on the first heat quantity, the second heat quantity supplied to the second air conditioning zone by the conditioned air blown out from the second passage, and the temperature estimation information including the temperature detected by the inside air temperature detecting means, the second air conditioning zone The first temperature adjusting unit is controlled based on an air conditioning condition including an estimating unit for estimating a temperature, a set temperature of the first temperature setting unit and a temperature detected by the inside air temperature detecting unit, and the second based on the air conditioning conditions including the presumed temperature of the second air-conditioning zone guess at a set temperature and the estimating means of the temperature setting means and control means for controlling said second temperature adjusting means, said control means, said When the temperature detected by the inside air temperature detecting means changes, a first process for bringing the temperature before the change closer to the temperature after the change over the first time, and the temperature before the change is longer than the first time. And a second process for approaching the changed temperature over a period of time 2, and the temperature obtained in the first process is used for controlling the first temperature adjusting means. The temperature obtained by two treatments There are a structure that is configured to estimate the temperature of the second air conditioning zone.

  According to this configuration, the temperature of the conditioned air blown from the first passage and the second passage is adjusted so that each zone has a set temperature. With this conditioned air, the first heat quantity is supplied to the first air conditioning zone and the second heat quantity is supplied to the second air conditioning zone, so that the first air conditioning zone and the second air conditioning zone are individually air-conditioned. During this air conditioning, the temperature of the air in the first air conditioning zone that has changed according to the magnitude of the first heat quantity is directly detected by the inside air temperature detecting means. The air conditioning state of the first air conditioning zone can be obtained from the temperature of the air in the first air conditioning zone and a value calculated by the set temperature of the first temperature setting means, for example, the target temperature. The air-conditioning state of the first air-conditioning zone affects the temperature of the air in the second air-conditioning zone when the first temperature setting means and the second temperature setting means have different set temperatures. On the other hand, since the second heat quantity has such a magnitude that the temperature of the air in the second air conditioning zone becomes the set temperature of the second temperature setting means, the second heat quantity affects the temperature of the air in the second air conditioning zone. That is, the temperature of the air in the second air-conditioning zone varies depending on the air-conditioning state of the first air-conditioning zone based on the first heat amount and the temperature detected by the inside air temperature detection means, and the second heat amount. Since the temperature of the second air-conditioning zone is estimated based on these, the temperature of the air in the second air-conditioning zone can be obtained with the accuracy required for air-conditioning control without providing temperature detecting means in the second air-conditioning zone. It becomes possible.

  In the second aspect of the invention, the temperature of the conditioned air blown out to the first air conditioned zone, the temperature of the conditioned air blown out to the second air conditioned zone, and the temperature of the air in the first air conditioned zone detected by the inside air temperature detecting means are used. 2 The temperature of the air-conditioning zone was estimated.

Specifically, a casing provided with a first passage and a second passage for supplying conditioned air to each of the first air-conditioning zone and the second air-conditioning zone in the vehicle interior, the casing provided with the first passage, First temperature adjusting means and second temperature adjusting means for adjusting the temperature of the conditioned air flowing through the second passage, first temperature setting means for the occupant to set the temperature of the first air conditioning zone, and Second temperature setting means for setting the temperature of the second air-conditioning zone; Inside air temperature detecting means arranged in the first air-conditioning zone; Temperature of conditioned air blown out from the first passage; Air blown out from the second passage Based on temperature estimation information including the temperature of the conditioned air and the temperature detected by the inside air temperature detecting means, the estimating means for estimating the temperature of the second air conditioning zone, the set temperature of the first temperature setting means, and the inside air temperature The first temperature adjusting means is controlled based on the air conditioning condition including the temperature detected by the exit means, and the set temperature of the second temperature setting means and the estimated temperature of the second air conditioning zone estimated by the estimating means Control means for controlling the second temperature adjusting means based on an air conditioning condition including: when the temperature detected by the inside air temperature detecting means is changed, the control means sets the temperature before the change to the first temperature. A first process for bringing the temperature close to the changed temperature over a period of time, and a second process for bringing the temperature before the change closer to the temperature after the change over a second time longer than the first time. The temperature obtained by the process is configured to be used for controlling the first temperature adjusting means, and the estimating means estimates the temperature of the second air-conditioning zone using the temperature obtained by the second process. The configuration is as follows.

  According to this configuration, the temperature of the conditioned air blown out from the first passage and the second passage is adjusted so that each zone has a set temperature. Thereby, the 1st air-conditioning zone and the 2nd air-conditioning zone are air-conditioned separately. During this air conditioning, the temperature of the air in the first air conditioning zone, which has changed due to the temperature of the conditioned air blown out from the first passage, is directly detected by the inside air temperature detecting means. The air conditioning state of the first air conditioning zone can be obtained from the temperature of the air in the first air conditioning zone and a value calculated by the set temperature of the first temperature setting means, for example, the target temperature. The air-conditioning state of the first air-conditioning zone affects the temperature of the air in the second air-conditioning zone when the first temperature setting means and the second temperature setting means have different set temperatures. On the other hand, the temperature of the conditioned air blown out from the second passage affects the temperature of the air in the second conditioned zone. That is, the temperature of the air in the second air-conditioning zone is determined by the air-conditioning state of the first air-conditioning zone based on the temperature of the air-conditioning air blown out from the first passage and the temperature detected by the inside air temperature detecting means, and the air-conditioning air blown out from the second passage. Varies with temperature. Since the temperature of the second air-conditioning zone is estimated based on these, the temperature of the air in the second air-conditioning zone can be obtained with the accuracy required for air-conditioning control without providing temperature detecting means in the second air-conditioning zone. It becomes possible.

  According to a third aspect of the present invention, the second air conditioning is performed using the temperature set by the first temperature setting means, the temperature set by the second temperature setting means, and the temperature of the air in the first air conditioning zone detected by the inside air temperature detecting means. The temperature of the zone was estimated.

Specifically, a casing provided with a first passage and a second passage for supplying conditioned air to each of the first air-conditioning zone and the second air-conditioning zone in the vehicle interior, the casing provided with the first passage, First temperature adjusting means and second temperature adjusting means for adjusting the temperature of the conditioned air flowing through the second passage, first temperature setting means for the occupant to set the temperature of the first air conditioning zone, and A second temperature setting means for setting the temperature of the second air conditioning zone, an inside air temperature detecting means arranged in the first air conditioning zone, a set temperature of the first temperature setting means, and a second temperature setting means. Estimating means for estimating the temperature of the second air-conditioning zone based on temperature estimation information including the set temperature and the temperature detected by the inside air temperature detecting means; the set temperature of the first temperature setting means and the inside air temperature detection Check by means And controlling the first temperature adjusting means based on the air conditioning condition including the measured temperature and including the set temperature of the second temperature setting means and the estimated temperature of the second air conditioning zone estimated by the estimating means. Control means for controlling the second temperature adjusting means based on a condition, and when the temperature detected by the inside air temperature detecting means changes, the control means takes the temperature before the change over a first time. A first process for approaching the temperature after the change and a second process for bringing the temperature before the change to the temperature after the change over a second time longer than the first time are obtained by the first process. The estimation unit is configured to estimate the temperature of the second air-conditioning zone using the temperature obtained in the second process. The configuration is as follows.

  According to this configuration, the conditioned air supplied to the first air-conditioning zone and the second air-conditioning zone is temperature-adjusted so as to be a target temperature calculated based on the set temperature of each zone. Thereby, the 1st air-conditioning zone and the 2nd air-conditioning zone are air-conditioned separately. During this air conditioning, the temperature of the air in the first air conditioning zone is directly detected by the inside air temperature detecting means. The air conditioning state of the first air conditioning zone can be obtained from the temperature of the air in the first air conditioning zone and a value calculated by the set temperature of the first temperature setting means, for example, the target temperature. The air-conditioning state of the first air-conditioning zone affects the temperature of the air in the second air-conditioning zone when the first temperature setting means and the second temperature setting means have different set temperatures. On the other hand, since the temperature of the air in the second air conditioning zone is set to the set temperature of the second temperature setting means, this set temperature affects the temperature of the air in the second air conditioning zone. That is, the temperature of the air in the second air conditioning zone includes the air conditioning state of the first air conditioning zone based on the temperature set by the first temperature setting means and the temperature detected by the inside air temperature detecting means, and the temperature set by the second temperature setting means. It depends on. Since the temperature of the second air-conditioning zone is estimated based on these, the temperature of the air in the second air-conditioning zone can be obtained with the accuracy required for air-conditioning control without providing temperature detecting means in the second air-conditioning zone. It becomes possible.

  In the invention of claim 4, in the invention of claim 1, the temperature estimation information includes a difference between the first heat quantity and the second heat quantity.

  According to this configuration, when there is a difference between the first heat amount and the second heat amount and the heat amount supplied to each zone is different, the second air-conditioning zone is strongly influenced by the first air-conditioning zone. . By including the difference between the first heat amount and the second heat amount in the temperature estimation information, the temperature of the air in the second air-conditioning zone is adjusted according to the strength of the influence of the second air-conditioning zone from the first air-conditioning zone. It becomes possible to guess.

  In the invention of claim 5, in the invention of claim 2, the temperature estimation information includes a difference between the temperature of the conditioned air blown from the first passage and the temperature of the conditioned air blown from the second passage.

  According to this configuration, when there is a difference between the temperature of the conditioned air blown from the first passage and the temperature of the conditioned air blown from the second passage, the second air conditioning zone is strongly influenced by the first air conditioning zone. By including the difference between the temperature of the conditioned air blown out from the first passage and the temperature of the conditioned air blown out from the second passage in the temperature estimation information, the second air-conditioning zone corresponds to the strength of the influence from the first air-conditioning zone. It becomes possible to estimate the temperature of the air in the second air conditioning zone.

  According to a sixth aspect of the present invention, in the third aspect of the invention, the temperature estimation information includes a change amount of the set temperature that is changed by operating at least one of the first temperature setting means and the second temperature setting means. And

  According to this configuration, when the occupant greatly changes the set temperature of the first temperature setting means, the temperature of the air in the first air-conditioning zone is large and quickly changes, so the temperature of the air in the second air-conditioning zone is also large. And it will change quickly. Further, even when the occupant greatly changes the set temperature of the second temperature setting means, the temperature of the air in the second air conditioning zone changes greatly and quickly. By including these change amounts of the set temperature in the temperature estimation information, it becomes possible to estimate the temperature of the second air-conditioning zone corresponding to the situation where the temperature of the air in the second air-conditioning zone changes.

  In the invention of claim 7, in the invention of claim 3 or 6, the temperature estimation information includes a difference between the set temperature of the first temperature setting means and the set temperature of the second temperature setting means.

  According to this configuration, when there is a difference between the set temperature of the first temperature setting means and the set temperature of the second temperature setting means, the larger the difference between the set temperatures, the more the second air conditioning zone is in the first air conditioning zone. It will be strongly influenced. By including the difference between the set temperature of the first temperature setting means and the set temperature of the second temperature setting means in the temperature estimation information, the second air conditioning zone corresponds to the magnitude of the influence received from the first air conditioning zone, The temperature of the second air conditioning zone can be estimated.

  In the invention of claim 8, in the invention of claim 7, the difference between the set temperature of the first temperature setting means and the set temperature of the second temperature setting means is the first temperature setting means from the set temperature of the second temperature setting means. The set temperature is subtracted.

  According to this configuration, the difference between the set temperature of the first temperature setting means and the set temperature of the second temperature setting means is obtained with reference to the set temperature of the second temperature setting means.

  According to a ninth aspect of the present invention, in any one of the sixth to eighth aspects of the present invention, the temperature estimation information changes in the set temperature by operating at least one of the first temperature setting means and the second temperature setting means. Then, the delay time required for the temperature of the air in the second air-conditioning zone to start to change is included.

  That is, generally, in the passenger compartment, when the set temperature of the first temperature setting means is changed, the temperature of the air in the first air conditioning zone does not change immediately, but gradually changes with a delay, Further, even when the set temperature of the second temperature setting means is changed, the temperature of the second air conditioning zone gradually changes with a delay. By including this delay time in the temperature estimation information, it becomes possible to estimate the temperature of the air in the second air-conditioning zone corresponding to the situation in which the temperature of the air in the second air-conditioning zone changes.

  According to a tenth aspect of the present invention, in the ninth aspect of the invention, an air volume changing means for changing the air conditioning air volume is provided, and the control means changes the delay time according to the air conditioning air volume changed by the air volume changing means.

  That is, if the air-conditioning air volume is increased by the air volume changing means, the air in the passenger compartment flows greatly, so that the air in the first air-conditioning zone and the air in the second air-conditioning zone are easily mixed, and the second air-conditioning zone is in the first air-conditioning area. Strongly affected by zones. On the other hand, if the air volume is reduced by the air volume changing means, the second air conditioning zone is relatively weakly affected by the first air conditioning zone. According to the above configuration, the delay time required for the temperature of the second air conditioning zone to start changing after the set temperature has changed corresponds to the strength of the influence that the second air conditioning zone receives from the first air conditioning zone. It becomes possible to set.

  According to an eleventh aspect of the present invention, in any one of the sixth to tenth aspects of the present invention, the estimating means has a predetermined holding time from when at least one of the first temperature setting means and the second temperature setting means is operated. It is assumed that the estimated value is held until it elapses.

  That is, generally, in the passenger compartment, even if the set temperature of the first temperature setting means is changed, the temperature of the air in the first air conditioning zone does not change immediately, and the setting of the second temperature setting means is performed. Similarly, when the temperature is changed, the temperature of the air in the second air conditioning zone does not change immediately. When these set temperatures are changed, until the predetermined holding time elapses from the time of change, by holding the value once estimated by the estimating means and prohibiting the update of the value, It becomes possible to estimate the temperature of the air in the second air-conditioning zone reflecting the change in the actual temperature state in the passenger compartment.

  According to a twelfth aspect of the invention, in the invention of the eleventh aspect, the apparatus is provided with an air volume changing means for changing the air conditioning air volume, and the holding time is set longer as the air conditioning air volume decreases.

  According to this configuration, as the air flow rate is decreased by the air volume changing means, the air in the first air conditioning zone and the air in the second air conditioning zone are less likely to be mixed, and the temperature of the air in the second air conditioning zone is less than that of the first air conditioning zone. It becomes difficult to change with the temperature of air. To cope with this, it is possible to lengthen the time for holding the value estimated by the estimation means.

  According to a thirteenth aspect of the present invention, in the eleventh aspect of the present invention, the control means selectively selects a plurality of air outlets provided in the casing so as to supply conditioned air to the respective parts of the first air conditioning zone and the second air conditioning zone. It is configured to open and close to switch the blowing mode, and the holding time is changed to a length corresponding to the switched blowing mode.

  According to this configuration, for example, when the blowing mode is in the vent mode and when in the foot mode, the time required for the air temperature in the second air-conditioning zone to change after the set temperature is changed is different. Become. Corresponding to this, it is possible to change the time for holding the value estimated by the estimation means.

  In the invention of claim 14, in the invention of claim 13, the holding time is set longer when the blowing mode is in the foot mode for supplying the conditioned air near the feet of the occupant than when in the other blowing mode. The configuration.

  That is, when the blowing mode is in the foot mode, the conditioned air supplied to one air-conditioning zone is less likely to mix with the conditioned air supplied to the other air-conditioned zone, compared to other cases such as the vent mode. The time required for the air temperature in the air-conditioning zone to change after the change is changed. It becomes possible to lengthen the holding time to cope with this.

  According to a fifteenth aspect of the invention, in any one of the sixth to tenth aspects of the invention, the control means performs air conditioning in a state where there is a difference between the set temperature of the first temperature setting means and the set temperature of the second temperature setting means. When started, the estimation means prohibits the estimation of the temperature of the second air-conditioning zone for a predetermined period, and the temperature of the first air-conditioning zone calculated using the temperature detected by the inside air temperature detection means is set to the second air-conditioning. It is assumed that the second temperature adjusting means is controlled as the zone temperature.

  According to this configuration, there is almost no difference in the temperature of both air-conditioning zones during the predetermined period when air-conditioning is not reaching both the air-conditioning zones in the passenger compartment immediately after the start of air-conditioning. By controlling the second temperature adjusting means using the temperature of the first air conditioning zone as the temperature of the second air conditioning zone, the control after the start of air conditioning can be simplified.

  According to a sixteenth aspect of the present invention, in the fifteenth aspect of the invention, while the operating state of the first temperature adjusting means and the second temperature adjusting means is substantially maximum on the heating side or the cooling side, the second air conditioning zone by the estimating means is used. The configuration is such that the estimation of the temperature is prohibited.

  The fact that the operating states of the first temperature adjusting means and the second temperature adjusting means are substantially maximum means that the temperatures of the first air conditioning zone and the second air conditioning zone are greatly deviated from the set temperature. Thus, when the temperature of the 2nd air conditioning zone has shifted | deviated largely from preset temperature, it is not necessary to estimate the temperature of a 2nd air conditioning zone. Therefore, by using the temperature of the first air conditioning zone as the temperature of the second air conditioning zone as in this configuration, air conditioning corresponding to the temperature state of the passenger compartment can be performed while simplifying the control.

  According to a seventeenth aspect of the present invention, in any one of the third, sixth to sixteenth aspects, the temperature estimation information includes a correction coefficient that is set according to the air conditioning state of the passenger compartment.

  That is, the magnitude of the influence that the second air conditioning zone receives from the first air conditioning zone differs depending on the air conditioning state of the passenger compartment. In this configuration, the estimated temperature of the second air conditioning zone can be corrected by the air conditioning state of the passenger compartment.

  In the invention of claim 18, in the invention of claim 17, the control means selectively selects a plurality of outlets provided in the casing so as to supply conditioned air to each part of the first air conditioning zone and the second air conditioning zone. The correction mode is changed to a value corresponding to the switched blowing mode.

  In this configuration, the position where the conditioned air is blown differs depending on the blowing mode, and the strength of the influence of the second air-conditioning zone on the first air-conditioning zone differs depending on the position where the conditioned air blows. It is possible to correct the estimated temperature so as to correspond to this blowing mode.

  According to a nineteenth aspect of the present invention, in the seventeenth or eighteenth aspect of the present invention, an outside air temperature detecting means for detecting a temperature outside the vehicle compartment is provided, and the correction coefficient is changed to a value corresponding to the temperature detected by the outside air temperature detecting means. The configuration is as follows.

  That is, the outside air temperature affects the air conditioning state of the passenger compartment. If the outside air temperature is greatly different from the air temperature in the first air conditioning zone, the outside air temperature is based on the air temperature in the first air conditioning zone. The temperature of the air in the second air conditioning zone to be estimated is strongly influenced by the outside air temperature. On the other hand, if the difference between the outside air temperature and the temperature of the air in the first air conditioning zone is small, the temperature of the air in the second air conditioning zone to be estimated based on the temperature of the air in the first air conditioning zone is equal to the outside air temperature. It will be almost unaffected. In this configuration, it is possible to correct the estimated temperature of the second air conditioning zone so as to correspond to the outside air temperature.

  According to a twentieth aspect of the present invention, in any one of the seventeenth to nineteenth aspects of the present invention, an air volume changing means for changing the air conditioning air volume is provided, and the correction coefficient is a value corresponding to the air conditioning air volume changed by the air volume changing means. The configuration is changed.

According to this configuration, if the air-conditioning air volume is increased by the air volume changing means, the air in the first air-conditioning zone and the air in the second air-conditioning zone are easily mixed, and the second air-conditioning zone strengthens the influence of the first air-conditioning zone. Will receive. On the other hand, if the air volume is reduced by the air volume changing means, the second air conditioning zone is weakly influenced by the first air conditioning zone. It is possible to correct the estimated temperature so as to correspond to the air-conditioning air volume .

In the invention of claim 2 1, in any one invention of claims 1 2 0, the control means is provided in the casing so as to supply conditioned air respectively to each part of the first air conditioning zone and the second air conditioning zone The plurality of outlets are selectively opened and closed according to at least the operating state of the first temperature adjusting means and the operating state of the second temperature adjusting means.

  According to this configuration, it is possible to automatically switch the blowing mode in consideration of the temperature of each conditioned air adjusted by the first temperature adjusting means and the second temperature adjusting means.

In the invention of claim 2 2, in the invention of claim 2 1, in the inner casing, a cooling heat exchanger, a heating heat exchanger disposed in the air flow downstream side of the cooling heat exchanger, A bypass passage for allowing the air that has passed through the cooling heat exchanger to flow by bypassing the heating heat exchanger is provided, and the first temperature adjusting means and the second temperature adjusting means are the amount of air flowing through the bypass passage. The control means is configured to selectively open and close the plurality of outlets of the casing based on an average opening degree of the first temperature adjusting means and the second temperature adjusting means. It is assumed that

  According to this configuration, the temperature of the conditioned air blown to the first air conditioning zone is changed by the opening degree of the first temperature adjusting means, and the temperature of the conditioned air blown to the second air conditioning zone is changed by the opening degree of the second temperature adjusting means. Is done. Since the blowing mode is selected based on the average opening degree of the first temperature adjusting means and the second temperature adjusting means, it is avoided that the blowing mode becomes uncomfortable for the passengers in both air conditioning zones.

In the invention of claim 2 3, in any one invention of claims 1 to 2 2 to the casing, the outside air introduction port for introducing outside the cabin air, and the inside air inlet for introducing the passenger compartment air, Inside / outside air switching means for opening and closing these inlets is provided, and the control means is based on at least the temperature detected by the outside air temperature detecting means for detecting the temperature outside the passenger compartment and the set temperature of the first temperature setting means. Then, the first target temperature, which is the target temperature of the first air conditioning zone, is calculated, and the second air conditioning is based on at least the temperature detected by the outside air temperature detecting means and the set temperature of the second temperature setting means. A second target temperature that is a target temperature of the zone is calculated, and the inside / outside air switching means includes a value calculated using at least one of the first target temperature and the second target temperature, and an inside air temperature detecting means. Detected by It is assumed to be configured to open and close the outside air introduction port and inside air introduction port based on the temperature and.

  According to this configuration, when the first target temperature or the second target temperature is lower than the temperature of the air in the first air-conditioning zone detected by the inside air temperature detecting means, the cooling efficiency is increased by using the inside air circulation. Thus, the conditioned air supplied to the air conditioning zone can be lowered. Further, when the temperature of the air in the first air-conditioning zone detected by the inside air temperature detecting means is, for example, a temperature at which the wind glass is likely to be fogged, it is possible to clear the fog of the wind glass by introducing outside air. become.

In the invention of claim 2 4, in any one invention of claims 1 to 2 2 to the casing, the outside air introduction port for introducing outside the cabin air, and the inside air inlet for introducing the passenger compartment air, Inside / outside air switching means for opening and closing these inlets is provided, inside the casing, a cooling heat exchanger, a heating heat exchanger disposed on the downstream side of the air flow of the cooling heat exchanger, and the above A bypass passage for flowing air that has passed through the heat exchanger for cooling bypassing the heat exchanger for heating, and the first temperature adjusting means and the second temperature adjusting means are configured to control the amount of air flowing through the bypass passage. The door is configured to change, and the control means includes a first temperature based on at least the temperature detected by the outside air temperature detecting means for detecting the temperature outside the passenger compartment and the set temperature of the first temperature setting means. The target temperature of the air conditioning zone A first target temperature is calculated, and a second target temperature that is a target temperature of the second air-conditioning zone is calculated based on at least the temperature detected by the outside air temperature detecting means and the set temperature of the second temperature setting means. The inside / outside air switching means is configured to calculate the outside air based on the difference between the value calculated using the average value of the first target temperature and the second target temperature and the temperature detected by the inside air temperature detecting means. It is configured to open and close the introduction port and the inside air introduction port.

  According to this configuration, for example, if the average value of the first target temperature and the second target temperature is lower than the temperature detected by the inside air temperature detecting means, both the air conditioning zones are increased by increasing the cooling efficiency as the inside air circulation. It is possible to quickly bring the temperature of the target temperature closer to the target temperature. Thus, by switching between the inside air circulation and the outside air introduction using the target temperatures of both air conditioning zones, it becomes possible for the passengers in both air conditioning zones to perform substantially satisfactory air conditioning.

In the invention of claim 2 5, in any one invention of claims 1 to 2 2 to the casing, the outside air introduction port for introducing outside the cabin air, and the inside air inlet for introducing the passenger compartment air, Inside / outside air switching means for opening and closing these inlets is provided, inside the casing, a cooling heat exchanger, a heating heat exchanger disposed on the downstream side of the air flow of the cooling heat exchanger, and the above A bypass passage for flowing air that has passed through the heat exchanger for cooling bypassing the heat exchanger for heating, and the first temperature adjusting means and the second temperature adjusting means are configured to control the amount of air flowing through the bypass passage. The door is configured to change, and the control means includes a first temperature based on at least the temperature detected by the outside air temperature detecting means for detecting the temperature outside the passenger compartment and the set temperature of the first temperature setting means. The target temperature of the air conditioning zone A first target temperature is calculated, and a second target temperature that is a target temperature of the second air-conditioning zone is calculated based on at least the temperature detected by the outside air temperature detecting means and the set temperature of the second temperature setting means. The inside / outside air switching means is configured to calculate the outside air based on a difference between a value calculated using the lower one of the first target temperature and the second target temperature and a temperature detected by the inside air temperature detecting means. It is configured to open and close the introduction port and the inside air introduction port.

Thereafter, in the control device 30, in consideration of output signals from the air temperature sensor 37, the engine water temperature sensor 64, and the like, the driver seat side air mix door 46 is set so that the temperature of the conditioned air in the driver seat side passage 41 becomes the target temperature. , The driver's seat side air mix door actuator 48 is operated to set the driver's seat side air mix door 46 to a desired opening.

  On the other hand, the target temperature of the conditioned air supplied to the passenger seat zone Ps is the operation detected by the set temperature of the passenger seat side temperature setting switch 69 and the inside air temperature sensor 65 until a predetermined time has elapsed after the start of air conditioning of the passenger compartment. It is determined based on the air conditioning conditions including the air temperature in the seat zone Dr, the amount of solar radiation on the passenger seat side detected by the solar sensor 67, and the outside air temperature detected by the outside air temperature sensor 66. The reason why the temperature of the inside air temperature sensor 65 is used as the air-conditioning condition until a predetermined time has elapsed since the start of air-conditioning is that air-conditioning is perfect even after the start of air-conditioning, even if the set temperature differs between the driver's seat and the passenger's seat This is because there is almost no temperature difference between the driver seat zone Dr and the passenger seat zone Ps. That is, the temperature of the driver's seat zone Dr is regarded as the temperature of the passenger seat zone Ps.

  The controller 30 calculates the opening degree of the passenger seat side air mix door 47 in the same manner as the opening degree of the driver seat side air mix door 46, and then calculates the passenger seat side air mix door. The door actuator 49 is operated to set the passenger seat side air mix door 47 to a desired opening. The air conditioning of the driver seat zone Dr and the passenger seat zone Ps is performed as described above.

  Next, the operation of the air conditioner 1 configured as described above will be specifically described. For example, when the temperature of the passenger compartment that has been left under the hot weather in the summer is lowered to the set temperature, the air temperature in both zones Dr and Ps is about the same as that immediately after the start of air conditioning. The opening degree of the mix door 46 and the passenger side air mix door 47 is set to 0% so that the maximum cooling capacity can be obtained. As time elapses, the temperature of the driver's seat zone Dr approaches the temperature set by the driver's seat side temperature setting switch 68. For example, the difference between the temperature of the driver's seat zone Dr and the set temperature becomes, for example, about 8 ° C to 10 ° C. The opening degree of the driver seat side air mix door 46 becomes larger than 0%. Similarly, on the passenger seat side, the opening degree of the passenger seat side air mix door 47 becomes larger than 0% over time.

  At the timing when the opening degree of one of the driver seat side air mix door 46 and the passenger seat side air mix door 47 becomes larger than 0%, the air conditioning of the same temperature is applied to the driver seat zone Dr and the passenger seat zone Ps until then. Since the wind is supplied, the temperature of the passenger seat zone Ps is substantially the same as the temperature of the driver seat zone Dr, that is, the temperature detected by the inside air temperature sensor 65. Therefore, at the timing when the opening degree of one air mix door becomes larger than 0%, the target temperature of the conditioned air supplied to the passenger seat zone Ps is the temperature detected by the inside air temperature sensor 65 and the passenger seat side temperature setting switch. On the other hand, the target temperature of the conditioned air supplied to the driver's seat zone Dr is the air conditioning including the temperature of the inside air temperature sensor 65 and the temperature of the driver's seat side temperature setting switch 68. Determined by conditions. Thereby, when the set temperatures are different between the driver's seat side and the passenger seat side, the difference between the temperature of the conditioned air supplied to the driver's seat zone Dr and the temperature of the conditioned air supplied to the passenger's seat zone Ps is different. Thus, the individual air conditioning is substantially started. In the winter season, the individual air conditioning of the driver's seat zone Dr and the passenger seat zone Ps is substantially started after a predetermined time has elapsed since the start of air conditioning.

  During the individual air conditioning, the control device 30 uses the temperature of the air in the driver's seat zone Dr and the driver's seat side target temperature calculated using at least the temperature set by the driver's seat side temperature setting switch 68. It is possible to obtain how far the temperature of the air in the zone Dr is from the driver's seat side target temperature as the air conditioning state of the driver's seat zone Dr. The air-conditioning state of the driver's seat zone Dr affects the temperature of the air in the passenger's seat zone Ps when the set temperatures of the driver's seat side temperature setting switch 68 and the passenger's seat side temperature setting switch 69 are different. .

  Further, since the temperature of the conditioned air blown to the passenger seat zone Ps is determined to be the passenger seat target temperature calculated using the set temperature of the passenger seat temperature setting switch 69, this set temperature is the assistant temperature. The temperature of the air in the seat zone Ps is affected. In other words, the temperature of the air in the passenger seat zone Ps is the driver seat zone Dr based on the driver seat target temperature calculated using the set temperature of the driver seat temperature setting switch 68 and the temperature detected by the inside air temperature sensor 65. The air-conditioning state and the passenger-side target temperature calculated using the set temperature of the passenger-side temperature setting switch 69 vary. The temperature estimation unit 91 estimates the temperature of the passenger seat zone Ps based on temperature estimation information including the temperatures of the driver seat side temperature setting switch 68, the inside air temperature sensor 65, and the passenger seat temperature setting switch 69. Even if a temperature sensor is not provided in the seat zone Ps, the temperature of the air in the passenger seat zone Ps can be estimated with an accuracy that can be used for air conditioning control.

  The temperature estimation unit 91 obtains an estimated temperature of the passenger seat zone Ps after the individual air conditioning is substantially started. And the control apparatus 30 removes the temperature of the internal temperature sensor 65 from the air-conditioning conditions which determine the target temperature of the front passenger seat zone Ps, and determines the target temperature incorporating the temperature estimated by the said temperature estimation part 91. FIG.

  When the temperature estimation unit 91 estimates the temperature of the air in the passenger seat zone Ps, the following equation is used.

TrPs = Tr + (SetPs−SetDr) × H
Here, TrPs is the estimated temperature of the air in the passenger seat zone Ps. Tr is a value obtained by performing a control value calculation process for converting the temperature detected by the inside air temperature sensor 65 into a control value. Further, SetPs is a set temperature on the passenger seat side, and SetDr is a set temperature on the driver seat side. H is a correction coefficient that is changed according to the air conditioning state of the passenger compartment. However, H is assumed not to be a negative value.

  The process performed in the temperature estimation unit 91 when estimating the temperature of the passenger seat zone Ps will be described based on the flowchart shown in FIG. This process is repeated at predetermined time intervals.

  In step S1 after the start of the flowchart, the temperature of the inside air temperature sensor 65 is input. In subsequent step S2, the set temperature SetDr of the driver seat side temperature setting switch 68 is input, and in step S3, the set temperature SetPs of the passenger seat side temperature setting switch 69 is input. Then, the process proceeds to step S4. In this step S4, when the temperature of the inside air temperature sensor 65 changes, as shown by a solid line in FIG. 5, a delay process for delaying the signal waveform by t seconds is performed. Thereafter, the process proceeds to step S5, and the control value calculation process is performed. This control value calculation process is a process in which, when the temperature detected by the inside air temperature sensor 65 changes, the temperature before the change gradually approaches the changed temperature over a predetermined time. Through this step S5, Tr that draws a curve as shown by the solid line in FIG. 5 is obtained. FIG. 5 shows the case where the temperature detected by the inside air temperature sensor 65 is changed from 20 ° C. to 22 ° C., but when the temperature is changed to the low temperature side, Tr which draws a curve below is obtained.

  In subsequent step S6, for example, when the set temperature SetDr is changed by the operation side temperature setting switch 68, the temperature before the change is gradually increased to the vicinity of the changed temperature over a predetermined time as shown by a solid line in FIG. The set temperature changing process is performed. FIG. 6 shows a case where SetDr is changed from 20 ° C. to 23 ° C., but the same is true when the temperature is changed to the low temperature side. The same process is performed when the set temperature SetPs of the passenger seat side temperature setting switch 69 is changed.

  Thereafter, the process proceeds to step S7, where Tr + (SetPs−SetDr) × H which is the right side of the above equation is calculated.

  In this step S7, for example, if the set temperature SetDr on the driver's seat side is set lower than the set temperature SetPs on the passenger seat side, the (SetPs−SetDr) × H term becomes a positive value, and the value of this term Is added to Tr. That is, if the set temperature SetDr on the driver's seat side is lower than the set temperature SetPs on the passenger seat side, the temperature of the air in the driver's seat zone Dr becomes lower than that on the passenger seat zone Ps. It becomes lower than the temperature of the air in the passenger seat zone Ps. Therefore, the estimated temperature of the passenger seat zone Ps can be obtained by adding the value obtained by subtracting the driver seat side set temperature SetDr from the passenger seat side set temperature SetPs to the temperature of the inside air temperature sensor 65 as in the above formula.

  On the other hand, if the set temperature SetDr on the driver's seat side is set higher than the set temperature SetPs on the passenger seat side, the (SetPs−SetDr) × H term becomes a negative value, and the absolute value of this term is the inside air temperature sensor. Will be subtracted from the temperature of 65. That is, if the driver seat side set temperature SetDr is higher than the passenger seat side set temperature SetPs, the temperature of the air in the driver seat zone Dr becomes higher than the passenger seat zone Ps, and therefore the temperature detected by the inside air temperature sensor 65 is higher. It becomes higher than the temperature of the air in the passenger seat zone Ps. Therefore, the estimated temperature of the passenger seat zone Ps can be obtained by subtracting the value obtained by subtracting the driver seat side set temperature SetDr from the passenger seat side set temperature SetPs from the temperature of the inside air temperature sensor 65 as in the above formula. .

  In the air conditioner 1, when the AUTO switch 71 is ON, the blowing mode is automatically set according to the opening degrees of the driver side air mix door 46 and the passenger side air mix door 47. Yes. For example, when both the air mix doors 46 and 47 are opened at about 55% or more during heating and the temperature of the conditioned air is high, the blowing mode is set to the foot mode. When the air-mix doors 46 and 47 are both opened at about 35% or less during cooling and the temperature of the conditioned air is low, the blowing mode is set to the vent mode. Moreover, when the opening degree of both the air mix doors 46 and 47 is about 45%, the blowing mode is set to the bi-level mode.

  When the opening degree of both the air mix doors 46 and 47 is different, the average opening degree of both the air mixing doors 46 and 47 is obtained, and the blow-out mode is set by this average opening degree. That is, when the opening degree of the driver side air mix door 46 is about 37% and the opening degree of the passenger side air mix door 47 is about 31%, the average opening degree is about 34%, and the blowing mode is bi-level. It becomes a mode. As a result, it is possible to avoid an unpleasant blowing mode for passengers in both zones Dr and Ps. Note that the opening degrees of the driver seat side air mix door 46 and the passenger seat side air mix door 47 described here are merely examples, and can be set to arbitrary values when determining the blowing mode.

  The air introduction mode is automatically set by at least one of the driver's seat side target temperature and the passenger seat side target temperature. For example, when the value calculated using at least the driver's seat side target temperature and the passenger's seat side target temperature is 5 ° C or more lower than the temperature detected by the inside air temperature sensor 65, until the difference becomes about 5 ° C, Rapid cooling is required, and the inside air circulation mode is set. When the driver's seat side target temperature and the passenger's seat side target temperature are different, the average value of both target temperatures is obtained, and the value calculated using this average temperature and the temperature of the inside air temperature sensor 65 are The air introduction mode is set by. That is, when the value calculated using the average temperature of the driver's seat side target temperature and the passenger's side target temperature is 10 ° C., the value calculated using this average temperature is detected by the inside air temperature sensor 65. When the temperature is lower by 5 ° C. or more than the applied temperature, the inside air circulation is performed until the difference becomes about 5 ° C. Further, when the set temperature of the driver's seat side temperature setting switch 68 is low and the driver's seat side target temperature is calculated to be low, the driver's seat occupant desires stronger cooling and requires low-temperature conditioned air. In this case as well, the cooling efficiency is improved as the inside air circulation mode.

  If the driver side target temperature and the passenger side target temperature are different when the air introduction mode is set, the air introduction mode may be set based on a value calculated using the lower target temperature. . A low target temperature means that a low-temperature conditioned air is required, and a comfortable cooling can be performed by setting the inside air circulation mode suitable for obtaining this low-temperature conditioned air.

  If the driver side target temperature and the passenger side target temperature are different when setting the air introduction mode, the air introduction mode may be set based on a value calculated using the driver side target temperature. . Thereby, it becomes possible to set to the air introduction mode suitable for the temperature of the conditioned air blown out to the driver's seat zone Dr, and it becomes possible to perform air conditioning giving priority to the driver's seat occupant.

  The operating state of the compressor uses a driver side target temperature calculated using at least a set temperature set by the driver side temperature setting switch 68 and at least a set temperature set by the passenger side temperature setting switch 69. The driver's seat side target temperature calculated in this way is set.

  For example, when the calculated value of the driver's side target temperature and the calculated value of the passenger's side target temperature are small and low-temperature conditioned air is required, the compressor operating time is increased to increase the maximum cooling capacity of the refrigeration cycle. To be able to get. When the calculated value of the driver's side target temperature and the calculated value of the passenger's side target temperature are not so low and weaker cooling may be used, the compressor operating time is shortened to reduce the cooling capacity of the refrigeration cycle. On the other hand, if the calculated value of the driver's side target temperature and the calculated value of the passenger's side target temperature are different, the average value of both target temperatures is obtained, and the compressor operating time is set by this average value. It has become. The operation time of the compressor is substantially the same as the connection time of the electromagnetic clutch 90, and the cooling capacity of the refrigeration cycle is changed by the control of the electromagnetic clutch 90.

  The operation time of the compressor may be set at the driver side target temperature without using the passenger side target temperature. As a result, the cooling capacity of the refrigeration cycle can be set with priority given to the driver's seat zone Dr. Further, the operation time of the compressor may be set based on the set temperature of the driver seat side temperature setting switch 68 and the passenger seat side temperature setting switch 69 which is operated to the low temperature side by the passenger. As a result, it is possible to increase the cooling capacity by extending the operation time of the compressor in accordance with a zone where strong cooling is required.

  Further, the operation time of the compressor may be changed based on the lower target temperature of the driver seat side target temperature and the passenger seat side target temperature. As a result, the refrigeration cycle can be operated in accordance with a zone where low-temperature conditioned air is required, and conditioned air at a desired temperature can be obtained.

  In addition, it takes time until the temperature of the conditioned air blown to the driver's seat zone Dr changes after the driver's seat side temperature setting switch 68 is operated, and even if the temperature of the conditioned air changes, the air in the driver's seat zone Dr changes. The temperature gradually changes with a delay. The air temperature in the passenger seat zone Ps affected by the temperature in the driver seat zone Dr gradually changes with a delay. Similarly, when the set temperature of the passenger seat side temperature setting switch 69 is changed, the temperature of the passenger seat zone Ps gradually changes with a delay. In the control device 30, as described in step S6 of the flowchart, even if both the temperature setting switches 68 and 69 are operated, the set temperature is not used as it is for estimating the temperature of the passenger seat zone Ps, and a time delay is caused. It is made to use after processing to give. Thereby, it becomes possible to estimate the temperature of the air in the zone Ps corresponding to the situation in which the temperature of the air in the passenger seat zone Ps changes.

  Further, for example, when the change in the set temperature is large, such as when the driver's seat passenger feels uncomfortable in the air-conditioning state and the set temperature is changed by 2 ° C. or more by the driver's seat side temperature setting switch 68, The air temperature will be large and change quickly. The temperature of the air in the passenger seat zone Ps affected by the driver seat zone Dr is also large and rapidly changes. In addition, for example, when the passenger in the passenger seat feels uncomfortable in the air-conditioning state, the amount of change in the set temperature similarly increases, and in this case, the temperature of the air in the passenger seat zone Ps is large and changes quickly. Become. Therefore, in the control device 30, when the set temperature change process in step S6 is performed, when the change amount of the set temperature is large, the control device 30 can approach the vicinity of the changed temperature in a short time compared to the case where the change amount is small. (Indicated by a two-dot chain line in FIG. 6).

  Further, when there is a difference between the set temperature of the driver seat side temperature setting switch 68 and the set temperature of the passenger seat side temperature setting switch 69, the passenger seat zone Ps is strongly influenced by the driver seat zone Dr. Since the temperature estimation information includes the difference between the setting temperature of the driver seat side temperature setting switch 68 and the setting temperature of the passenger seat side temperature setting switch 69, the magnitude of the influence of the passenger seat zone Ps from the driver seat zone Dr. It is possible to estimate the temperature of the zone corresponding to When obtaining this difference, the setting temperature of the driver's seat side temperature setting switch 68 is subtracted from the setting temperature of the passenger's seat side temperature setting switch 69, so that the setting temperature of the driver's seat side temperature setting switch 68 is used as a reference. Thus, it is possible to obtain how high or low the set temperature of the passenger seat side temperature setting switch 69 is.

  Further, the control device 30 changes the time for the temperature before the change in the set temperature changing process to approach the vicinity of the temperature after the change so as to correspond to the air-conditioning air quantity changed by the air quantity changeover switch 73. That is, when the air-conditioning air volume is large, the air in the passenger compartment greatly flows, so that the air in the driver's seat zone Dr and the air in the passenger's seat zone Ps are easily mixed, and the passenger's seat zone Ps strengthens the influence of the driver's seat zone Dr. Will receive. On the other hand, if the air-conditioning air volume is decreased by the air volume switching switch 73, the passenger seat zone Ps is weakly affected by the driver seat zone Dr. Therefore, when the air volume is large, the time for the set temperature changing process is shortened, and when the air volume is small, the time is increased. Thereby, the delay time required for the temperature of the passenger seat zone Ps to start changing after the set temperature has changed can be set in accordance with the strength of the influence that the passenger seat zone Ps receives from the driver seat zone Dr. As a result, the temperature of the passenger seat zone Ps can be obtained with high accuracy.

  In addition, the correction coefficient H used when estimating the temperature of the passenger seat zone Ps in the above equation is changed to a value corresponding to the switched blowing mode. That is, when the blowing mode is the vent mode, the conditioned air blown out from the driver-side vent ports 5 and 6 and the conditioned air blown out from the passenger-side vent ports 7 and 8 are likely to be mixed. On the other hand, when the blow-out mode is the foot mode, the conditioned air blown from the foot duct 52 on the driver seat side and the conditioned air blown from the foot duct 56 on the passenger seat side are mixed due to the presence of the floor tunnel, the center console 10 and the like. Hateful. Thus, the blowing mode indicates the air conditioning state of the passenger compartment, and the strength of the influence on the passenger seat zone Ps from the driver's seat zone Dr differs depending on the blowing mode. To make the difference in the set temperature easy to appear in the estimated temperature, and when in the foot mode, the correction coefficient H is reduced to make the difference in the set temperature difficult to appear in the estimated temperature. It can be obtained with high accuracy.

  In addition, the correction coefficient H in the above equation is changed to a value corresponding to the outside air temperature detected by the outside air temperature sensor 66. That is, the outside air temperature affects the air conditioning state of the passenger compartment. If the outside air temperature is significantly different from the air temperature in the driver seat zone Dr, the outside air temperature is based on the air temperature in the driver seat zone Dr. The temperature of the air in the passenger seat zone Ps to be estimated is strongly influenced by the outside air temperature. On the other hand, if the difference between the outside air temperature and the temperature of the air in the driver's seat zone Dr is small, the temperature of the air in the passenger seat zone Ps to be estimated based on the temperature of the air in the driver's seat zone Dr is equal to the outside air temperature. It will be almost unaffected. Corresponding to the influence of the outside air temperature, if the difference between the outside air temperature and the inside air temperature is large, the correction coefficient H is increased to make the difference in the set temperature easily appear in the estimated temperature, and if the difference is small, the correction coefficient H is set. Decrease so that the difference in the set temperature does not appear in the estimated temperature.

  The correction coefficient H is changed to a value corresponding to the air conditioning air volume. When the air-conditioning air volume is large and the passenger seat zone Ps is strongly influenced by the driver's seat zone Dr, the correction coefficient H is increased to make the difference in the set temperature easily appear in the estimated temperature, and the air-conditioning air volume is small and the passenger seat zone Ps. Is hardly affected by the driver's seat zone Dr, the correction coefficient H is decreased to make it difficult for the difference in the set temperature to appear in the estimated temperature, so that the temperature of the passenger seat zone Ps can be obtained with high accuracy. Become.

  In addition, when the temperature detected by the inside air temperature sensor 65 changes, the control device 30 has a first process for bringing the temperature before the change closer to the temperature after the change over time t1, as shown in FIG. The second process of bringing the temperature before the change closer to the vicinity of the temperature after the change over time t2 longer than t1 is performed. FIG. 7 shows a case where the temperature detected by the inside air temperature sensor 65 changes from 20 ° C. to 22 ° C.

  And the said control apparatus 30 determines the target temperature by the side of a driver's seat using the temperature obtained by the 1st process, and operates the driver's seat side air mix door 46. FIG. Thereby, for example, when the temperature detected by the inside air temperature sensor 65 changes suddenly, the temperature can be adjusted smoothly. In addition, when the temperature of the driver's seat zone Dr changes, the temperature of the air in the passenger seat zone Ps does not change immediately but gradually changes with a delay. The temperature estimation unit 91 estimates the temperature of the passenger seat zone Ps using the temperature obtained in the second process. This makes it possible to perform air conditioning that reflects changes in the temperature state in the actual passenger compartment.

  The control device 30 keeps the temperature value once estimated in the passenger seat zone Ps and prohibits the update until a predetermined holding time elapses after the driver-side temperature setting switch 68 is operated. Yes. That is, even if the set temperature on the driver's seat side is changed, the temperature in the driver's seat zone Dr does not change immediately, and the temperature in the actual passenger compartment is maintained by holding the temperature value corresponding to this. It becomes possible to perform air conditioning reflecting the change of the state. Similarly, when the passenger seat side temperature setting switch 69 is operated, the estimated temperature value of the passenger seat zone Ps is held until a predetermined holding time elapses.

  Also, when the set temperature is changed, the smaller the air-conditioning air volume, the less likely the air temperature in each zone Dr, Ps changes. Therefore, the lower the air-conditioning air volume, the higher the air-conditioning air volume. You may lengthen the time. In addition, when the blowing mode is, for example, the vent mode or the foot mode, the air temperature in each of the zones Dr and Ps changes after the set temperature is changed in the foot mode. Since the required time becomes long, the holding time may be extended in the foot mode so as to correspond to the air conditioning state of the passenger compartment.

  As described above, according to the air conditioner 1 according to this embodiment, the driver's seat zone detected by the set temperature of the driver's seat side temperature setting switch 68, the set temperature of the passenger's seat side temperature setting switch 69, and the inside air temperature sensor 65. Since the temperature of the passenger seat zone Ps is estimated using the temperature of the Dr air, the temperature of the conditioned air to the driver seat zone Dr and the passenger seat zone Ps is appropriately determined while avoiding an increase in the number of parts. Comfortable air conditioning can be realized for each zone.

  In this air conditioner 1, the temperature of the conditioned air blown to the driver's seat zone Dr changes according to the temperature set by the driver's seat side temperature setting switch 68, and the passenger seat zone Ps changes according to the temperature set by the passenger's seat side temperature setting switch 69. The temperature of the conditioned air that blows out will change. Therefore, the temperature of the air in the passenger seat zone Ps depends on the air conditioning state of the driver seat zone Dr according to the temperature of the conditioned air blown out from the driver seat side passage 41 and the temperature detected by the inside air temperature sensor 65, and from the passenger seat side passage 42. It is possible to estimate based on the temperature of the conditioned air blown out. In this case, when there is a difference between the temperature of the conditioned air blown from the driver seat side passage 41 and the temperature of the conditioned air blown from the passenger seat side passage 42, the passenger seat zone Ps is strongly influenced by the driver seat zone Dr. By including the difference between the temperature of the conditioned air blown out from the driver seat side passage 41 and the temperature of the conditioned air blown out from the passenger seat side passage 42 in the temperature estimation information, the passenger seat zone Ps is strongly influenced from the driver seat zone Dr. Accordingly, the temperature can be estimated, and the temperature of the air in the passenger seat zone Ps can be estimated with high accuracy.

  Further, the amount of heat supplied to the driver's seat changes as the temperature of the conditioned air blown to the driver's seat zone Dr changes according to the temperature set by the driver's seat side temperature setting switch 68. Further, the amount of heat supplied to the passenger seat changes as the temperature of the conditioned air blown to the passenger seat zone Ps changes according to the temperature set by the passenger seat side temperature setting switch 69. Accordingly, the temperature of the air in the passenger seat zone Ps can be estimated based on the air conditioning state of the driver seat zone Dr based on the driver seat supplied heat amount and the temperature detected by the inside air temperature sensor 65, and the passenger seat supplied heat amount. It is. In this case, if there is a difference between the amount of heat supplied to the driver's seat and the amount of heat supplied to the passenger seat, and the amount of heat supplied to each zone Dr, Ps is different, the passenger seat zone Ps is influenced by the driver's seat zone Dr. Take it stronger. By including the difference between the driver's seat supply heat amount and the passenger seat supply heat amount in the temperature estimation information, it is possible to estimate the air temperature corresponding to the strength of the influence of the passenger seat zone Ps from the driver seat zone Dr. Thus, the temperature of the air in the passenger seat zone Ps can be estimated with high accuracy.

  In this embodiment, the first air conditioning zone is the driver's seat zone Dr and the second air conditioning zone is the passenger seat zone Ps. However, the present invention is not limited to this, and the first air conditioning zone is the passenger seat zone Ps. The zone may be the driver's seat zone Dr. Further, the front zone of the passenger compartment may be the first air conditioning zone and the rear side may be the second air conditioning zone.

  In this embodiment, the first temperature adjusting means and the second temperature adjusting means are constituted by plate-like doors, but may be constituted by, for example, a film-like opening / closing member or the like.

  In this embodiment, the solar radiation sensor 67 is directional. However, a solar radiation sensor dedicated to the driver's seat zone and a solar radiation sensor dedicated to the passenger seat zone may be provided in the passenger compartment. .

  As described above, the vehicle air conditioner according to the present invention can be used, for example, to individually air-condition the driver's seat side and the passenger seat side of the passenger compartment of an automobile.
