  PMV (Predict Mean Vote) is a comfort evaluation index devised by Dr. Fanger in 1970 and evaluates human thermal sensation within a range of ± 3 with PMV = 0 as Natural. it can. For example, PMV and thermal sensation are as shown in [Table 1] below. A characteristic of PMV is that it can be directly evaluated from the four thermal elements (air temperature, wind speed, humidity, and radiation) of the thermal sensation. When PMV = 0, 80% or more of people show a neutral thermal sensation. The PMV can be calculated from the above four elements and the amount of human clothes and activity.

  Here, based on FIGS. 3-6, control of the air volume adjustment damper 43 by the controller 51 is explained in full detail. The controller 51 includes a CPU, a memory, and the like. The CPU 51 executes a computer program stored in the memory to control the blower 2 and the dampers 24, 41, 42 as described above. Alternatively, processing as shown in FIG. 3 is performed.

That is, the ratio of the first angle θ _{1 is} the surface area ratio a used in the equation (1), and the ratio of the fourth angle θ _{4 is} the surface area ratio b used in the equation (1). In this case, for example, the surface area ratio a is 0.8 and the surface area ratio b is 0.2. Further, the surface area ratio a, b used in the formula (2) is the front end 3A-1 and the rear end portion of the second predetermined position P ₂ and the window glass 3A of the interior side center 9B as shown in FIG. 4 (b) the fourth straight line L ₄ connecting the 3A-2, the sixth angle formed between the fifth angle theta ₅ formed by the fifth straight L _5, a sixth straight line L ₆ parallel to the window pane 3A and the fourth straight line L ₄ is the ratio of the eighth angle theta ₈ is the sum (theta ₆ + theta ₇₎ of the seventh angle theta ₇ formed between the fifth straight line L ₅ and theta ₆ and the sixth straight line L ₆ is. That is, the ratio of the fifth angle θ _{5 is} the surface area ratio a used in the expression (2), and the ratio of the eighth angle θ _{8 is} the surface area ratio b used in the expression (2). In this case, for example, the surface area ratio a is 0.3 and the surface area ratio b is 0.7.

  Similarly, in the case of the passenger 10, although not shown, the surface area ratios a and b used in the expression (1) are the first predetermined position of the vehicle window side 10 </ b> A and the front and rear ends of the window glass 3 </ b> B. The first angle formed by the first straight line and the second straight line connecting the second straight line, the second angle formed by the third straight line parallel to the window glass 3B and the first straight line, the third straight line, and the second straight line are formed. The ratio of the first angle to the fourth angle which is the sum of the third angle and the ratio of the first angle is the surface area ratio a (e.g., 0.8) used in the equation (1), and the ratio of the fourth angle is (1). The surface area ratio b used in the equation (for example, 0.2). Further, the surface area ratios a and b used in the expression (2) are the fifth angle formed by the fourth straight line and the fifth straight line connecting the second predetermined position of the vehicle interior side portion 10B and the front and rear ends of the window glass 3B. The ratio of the sixth angle formed by the sixth straight line parallel to the window glass 3B and the fourth straight line and the eighth angle which is the sum of the seventh angle formed by the sixth straight line and the fifth straight line. Thus, the ratio of the fifth angle is the surface area ratio a (for example, 0.3) used in the expression (2), and the ratio of the eighth angle is the surface area ratio b (for example, 0.7) used in the expression (2).

As shown in FIG. 3, the interior window glass side radiation temperature T _EA and the interior center side radiation temperature T _EB obtained by the radiation temperature calculation unit 61 are output to the PMV calculation unit 66. The in-vehicle temperature sensor 52, the solar radiation amount sensor 53, and the radiation temperature calculation unit 61 constitute radiation temperature setting means.

In the first season determination unit 62, for example, 30 ° C. is set as the first set temperature, and for example, 15 ° C. is set as the second set temperature lower than the first set temperature. Compared with T _out , when the outside air temperature T _out > the first set temperature (30 ° C.), it is determined that it is “summer”, and the second set temperature (15 ° C.) ≦ the outside air temperature T _out ≦ the first set temperature When it is (30 ° C.), it is determined that it is “spring / autumn”, and when the outside air temperature T _out <the second set temperature (15 ° C.), it is determined that it is “winter”, and this determination result is sent to the humidity determining unit 63. Output.

  In the humidity determination unit 63, if the vehicle interior humidity is “summer” based on the determination result of the first season determination unit 62 and the preset value of the vehicle interior humidity for each season, high humidity (for example, 60% RH) ), If it is “spring and autumn”, it is determined to be intermediate humidity (for example, 30% RH), and if it is “winter”, it is determined to be low humidity (for example, 10%). The outside air temperature sensor 54, the first season determination unit 62, and the humidity determination unit 63 constitute a humidity setting unit. The in-vehicle humidity determined here is a humidity that is expected on the assumption that the air-conditioning of the vehicle is performed by the automobile air conditioner.

In the second season determination unit 64, as in the first season determination unit 62, for example, 30 ° C. is set as the first set temperature, and for example, 15 ° C. is set as the second set temperature lower than the first set temperature. The set temperature and the outside air temperature T _out are compared, and when the outside air temperature T _out > the first set temperature (30 ° C.), it is determined that “summer” and the second set temperature (15 ° C.) ≦ When the outside air temperature T _out ≦ first set temperature (30 ° C.), it is determined that “spring and autumn”, and when the outside air temperature T _out <second set temperature (15 ° C.), it is determined that “winter”. The determination result is output to the clothing amount determination unit 65.

  Based on the determination result of the second season determination unit 64 and the preset value of the clothing amount for each season, the clothing amount determination unit 65 sets a small amount (for example, 0.1 clo) for “summer”, “ If it is “spring / autumn”, it is determined as an intermediate amount (for example, 0.3 clo), and if it is “winter”, it is determined as a large amount (for example, 1.4 clo), and these results are output to the PMV calculation unit 66. The outside air temperature sensor 54, the second season determination unit 64, and the clothing amount determination unit 65 constitute a clothing amount setting unit. The first season determination unit 62 and the second season determination unit 64 are integrated into one season determination unit, and the determination result of the integrated season determination unit is output to the humidity determination unit 63 and the clothing amount determination unit 65. May be.

  The activity amount setting unit 67 serving as the activity amount setting means outputs the driver-side activity amount and the passenger-side activity amount, which are preset seat-specific activity amounts, to the PMV calculation unit 66. The driver's seat side activity amount is a predicted value of the activity amount of the driver 9 sitting in the driver's seat 5. Since the driver 9 is driving and moving his / her body, the activity amount is predicted to be relatively large, so the driver's seat side activity amount is set to 70 kcal / h, for example. The passenger seat side activity amount is a predicted value of the activity amount of the passenger 10 sitting in the passenger seat 6. Since the passenger 10 does not move much, the activity amount is predicted to be relatively small, so the passenger side activity amount is set to 58 kcal / h, for example.

  In the wind speed determination unit 68 serving as the wind speed setting means, expected wind speed data representing the relationship between the blower voltage, the blowing mode, and the expected wind speed that can be represented by a characteristic graph as shown in FIG. 5 is set in advance. This expected wind speed data was determined by experiment. The wind speed determination unit 68 performs the following processing based on the predicted wind speed data.

First, the blowing mode 69 set by the controller 51 based on the operation of the air conditioning operation unit 55, the voltage 70 of the blower 21 adjusted by the controller 51 based on the operation of the air conditioning operation unit 55, etc. Based on this, the air speeds of the conditioned air blown from the side face outlets 12A and 12B and the conditioned air blown from the center face outlets 13A and 13B are predicted. That is, the wind speed at the side windows 9A and 10A (the left shoulder and arm) of the driver 9 and the passenger 10 and the central sides 9B and 10B (the right shoulder and arm) of the vehicle is predicted. For example, as illustrated in FIG. 5, when the blower voltage 70 is V ₁ and the blowing mode 69 is the face mode, the expected wind speed is v ₁ .

  A target control amount α is input from a target control amount calculation unit 71 (details will be described later). The target control amount α is a target value of the opening adjustment amount of the air volume adjustment damper 43. As shown in FIG. 1, the air volume adjustment damper 43 can rotate to the inlet side of the side duct 33 and to the inlet side of the center duct 34. Here, the opening degree of the air volume adjusting damper 43 is 0% when the air volume adjusting damper 43 rotates to the inlet side of the side duct 33 and closes the inlet (in the state of the g position), and the air volume adjusting damper. When 43 turns to the entrance side of the center side duct 34 and closes the entrance (in the state of the h position), the air volume adjusting damper 43 is also on the entrance side of the side duct 33 and the center side duct 34. It is assumed that the state of the i position that is not rotated (not tilted) at the entrance side is 50%.

The predicted wind speed data is for predicting the wind speed when the air volume adjusting damper 43 is at the initial opening (for example, 50%). As shown in FIG. 3, the wind speed determination unit 68 uses the predicted wind speed data, the predicted wind speed predicted based on the blowing mode 69 and the blower voltage 70, and the target control amount α to determine whether the driver 9 who asked 10 of the interior window glass side 9A, and wind velocity v _a of 10A (such as the left shoulder-arm unit), interior side center 9B, a wind velocity v _B at 10B (such as the right shoulder-arm portion) Then, these wind speeds v _A and v _B are output to the PMV calculation unit 66.

As a specific example, if the target control amount α is 3%, for example, and the initial opening degree of the air volume adjustment damper 43 (opening degree when the air volume adjustment damper 43 starts control) is 50%, for example, the air volume adjustment damper 43 is The opening degree is further increased by 3% from the state of the initial opening degree of 50%, and the opening degree becomes 53%. That is, the ratio of the opening on the inlet side of the side duct 33 is 53%, and the ratio of the opening on the inlet side of the center duct 34 is 47%. As a result, the damper opening on the inlet side of the side duct 33 is increased by 3%, so the air speed (air volume) of the conditioned air blown to the driver 9 and the passenger 10 from the side face outlets 12A and 12B is 3. On the other hand, the damper opening on the inlet side of the center side duct 34 is reduced by 3%, so that the air speed of the conditioned air blown to the driver 9 and the passenger 10 from the center face outlets 13A and 13B ( The air volume is reduced by 3%. Therefore, in this case, the wind speed determination unit 68 increases the predicted wind speed obtained based on the predicted wind speed data by 3% (multiplied by 53/50) and conditioned air blown out from the side face outlets 12A and 12B. wind speed v while the _a, the expected wind speed data such as as small as 3% fraction of the expected wind speed obtained based (47/50 multiplied by), the conditioned air blown center face outlet 13A, the 13B wind velocity v _B.

Note that the initial value of the target control amount α is 0, and the initial values of the wind speeds v _A and v _B are the expected wind speeds obtained based on the expected wind speed data.

In the PMV calculation unit 66, the vehicle interior temperature T _in input from the vehicle interior temperature sensor 52, the vehicle interior window glass side radiation temperature T _EA and the vehicle interior center side radiation temperature T _EB input from the radiation temperature computation unit 66, and the humidity determination unit 63 PMV calculation based on the input vehicle humidity, the amount of clothes input from the amount-of-clothing determination unit 65, the amount of activity input from the activity amount setting unit 67, and the wind speeds v _A and v _B input from the wind speed determination unit 68 The vehicle window glass side PMV _A which is the PMV value of the driver's 9 and passenger's 10 interior window glass side portions 9A and 10A (shoulders, arms, etc.), and the driver 9 and passenger's 10 interior side of the vehicle The vehicle center side PMV _B which is the PMV value of the parts 9B, 10B (shoulders, arms, etc.) is obtained, and the vehicle window glass side PMV _A and the vehicle center side PMV _B are output to the target control amount calculation unit 71.

Specifically, the interior window glass side PMV _A, and the interior temperature T _in, and the interior window glass side radiation temperature T _EA, and inside humidity, and amount of clothing, and activity amount, based on the wind velocity v _A, PMV Obtained by calculation. The in-vehicle center side PMV _B is obtained by PMV calculation based on the _in- vehicle temperature T _in , the in-vehicle central side radiation temperature T _EB , the in-vehicle humidity, the amount of clothes, the amount of activity, and the wind speed v _B.

The target control amount calculation unit 71 obtains the target control amount α by the following equation (3) based on the in-car window glass side PMV _A and the in-car center side PMV _B input from the PMV calculation unit 66, and the air volume adjustment damper driving unit. 72 and the wind speed determination unit 68 respectively. As described above, the initial value of the target control amount α is 0.

α = m | PMV _A −PMV _B | (3)

In Formula (3), m is a constant. The target control amount α is obtained by multiplying the absolute value of the difference (PMV _A −PMV _B ) between the interior window glass side PMV _A and the interior center side PMV _B by a constant m as shown in Expression (3). The constant m may be appropriately determined by experiments or the like so that the target control amount α at this time becomes a value suitable for equalizing the vehicle interior window glass side PMV _A and the vehicle interior center side PMV _B.

The air volume adjustment damper drive unit 72 performs drive control of a motor that is an actuator for rotating the air volume adjustment damper 43 based on the target control amount α input from the target control amount calculation unit 71, so that the interior window glass side The opening adjustment of the air volume adjustment damper 43 is performed so that PMV _A and the in-vehicle center side PMV _B become equal. As described above, the target control amount α is a target value of the opening adjustment amount of the air volume adjustment damper 43, and is a relative value from the initial opening (for example, 50%) of the air volume adjustment damper 43. Is 3%, the air volume adjustment damper 43 is adjusted to an opening of 53%.

  FIG. 6 shows the change in the ratio of the blown air volume on the vehicle window side and the blown air volume on the center side of the vehicle according to the opening of the air volume adjusting damper 43, that is, the blown air volume (wind speed) from the side face air outlets 12A and 12B. The change of the ratio of the blowing air volume (wind speed) from the center face outlets 13A and 13B is shown. As shown in FIG. 6, the ratio of the blown air volume on the in-car window side increases as the opening of the air volume adjusting damper 43 increases, while the ratio of the blown air volume on the vehicle center side decreases, and the air volume adjusting damper 43 When the opening degree is 50%, the ratio of the blown air volume on the vehicle interior window glass side is equal to the ratio of the blown air volume on the vehicle center side. And if the opening degree of the air volume adjustment damper 43 increases more than 50%, the ratio of the blown air volume on the vehicle interior window glass side becomes larger than the ratio of the blown air volume on the vehicle center side.

  Therefore, when the opening degree of the air volume adjustment damper 43 is increased from 50% to 53%, for example, the air speed (air volume) of the conditioned air blown out from the side face blowout ports 12A and 12B and the air blown out from the center face blowout ports 13A and 13B. The ratio of the air speed (air volume) of the conditioned air is adjusted as shown in FIG. 6, and the air speed (air volume) of the conditioned air blown out from the side face outlets 12A and 12B is blown out from the center face outlets 13A and 13B. It becomes larger than the wind speed (air volume) of the conditioned air.

For this reason, in the winter season, the warm air velocity (air volume) blown from the side face outlets 12A and 12B during the heating operation is higher than the warm air velocity (air quantity) blown from the center face outlets 13A and 13B. Therefore, the interior window glass side PMV _A and the interior center side PMV _B are equal. In summer, the air velocity (air volume) blown from the side face air outlets 12A and 12B during the cooling operation is higher than the air speed (air volume) blown from the center face air outlets 13A and 13B. Therefore, the interior window glass side PMV _A and the interior center side PMV _B become equal.

As described above, according to the air-conditioner for vehicle of the embodiment, and the interior temperature T _in, the side face outlet 12A, the wind speed v _A and the center face outlet 13A of the conditioned air blown from 12B, from 13B The wind speed v _{B of the} conditioned air to be blown out, the vehicle window glass side radiation temperature T _EA and the vehicle interior center side radiation temperature T _EB such as radiation that is transmitted to the passengers (driver 9 and passenger 10) through the window glasses 3A and 3B, By performing PMV calculation based on the interior humidity, the amount of occupant's clothing, and the amount of activity of the occupant, the interior window glass side PMV _A that is the PMV value of the interior window side portions 9A, 10A of the passenger's upper body , the upper body of the occupant of the vehicle center side 9B, 10B obtains the vehicle center side PMV _B is a PMV value, based on the the vehicle window glass side PMV _a and the interior central side PMV _B, vehicle thyris usitata Scan side PMV so that the _A and the interior central side PMV _B equal, adjusting the side face outlet 12A, and the wind speed of the conditioned air blown from 12B, the center face outlet 13A, the ratio of the wind speed of the conditioned air blown from 13B Therefore, it is possible to improve the occupant's comfort by reliably removing the influence of the cold radiation and the thermal radiation transmitted through the window glasses 3A and 3B.

The means for adjusting the air volume (wind speed) is provided between the inlet of the side duct 33 leading to the side face outlets 12A and 12B and the inlet of the center side duct 34 leading to the center face outlets 13A and 13B.
