Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner capable of independently controlling the temperature of a first air conditioning zone and the temperature of a second air conditioning zone in a room.

[0002]

2. Description of the Related Art As described in, for example, Japanese Patent Application Laid-Open No. 5-286338, a target blowout temperature of each seat is calculated from a driver-side set temperature, a passenger-side set temperature, an inside air temperature, an outside air temperature, and the like. In a vehicle air-conditioning system that independently controls the blowout temperature to each seat based on the target blowout temperature, when the driver-side set temperature and the passenger-side set temperature are different, depending on the difference between the two set temperatures. It is known that the temperature of each seat is controlled more accurately by correcting each target outlet temperature.

[0003]

By the way, it is difficult to control the temperature of the driver's seat and the temperature of the passenger's seat independently when the amount of air blown into the passenger compartment is small. That is, if the amount of blown air is small, it is not possible to make a predetermined difference in the amount of heat supplied to each seat unless there is a considerable difference in the temperature of the blown air. However, in reality, if there is too much temperature difference in the air blown to each seat, the passengers will feel uncomfortable.
It is not possible to make the blowing air have a temperature difference.

As described above, it is difficult to independently control the temperature of each seat unless there is a certain amount of air flow, but the above-mentioned known art does not describe anything about it. Therefore, the above-mentioned known technique may be effective when the blown air volume is large to some extent, but is meaningless when the blown air volume is small. Further, the above problem does not occur only in the vehicle air conditioner in which the temperature of the driver's seat and the passenger's seat are independently controlled, and the temperature control of the first air conditioning zone and the second air conditioning zone is independently performed. The same applies to the air conditioners that operate.

It is an object of the present invention to provide an air conditioner capable of independently controlling the temperatures of the air conditioning zone and the second air conditioning zone.

[0012]

According to the invention described in claims 1 to 8 , the deviation-corresponding air flow rate calculating means is a deviation between the magnitude of the first signal and the magnitude of the second signal (in the invention of claim 6).
Is the temperature of the first air conditioning zone and the temperature of the second air conditioning zone
And the invention according to claim 7, the first target outlet temperature
The larger the difference between the degree and the second target outlet temperature) , the larger the air flow rate is calculated. The final blown air volume of the blower means is equal to or larger than the deviation-corresponding blown air volume calculated by the deviation-corresponding blown air volume calculating means.

That is, the larger the deviation, the larger the amount of heat supplied to the first air conditioning zone and the second air conditioning zone. Therefore, as in the present invention, as the deviation increases, the amount of air blown by the air blower is increased, so that the amount of heat supplied to each zone can be increased even if the difference in blowout temperature to each zone is not so large. . Therefore, the temperature of each air conditioning zone can be controlled independently regardless of the deviation.

Particularly, in the invention described in claims 1 to 5 , the air-conditioning air flow rate calculating means calculates the air flow rate necessary for so-called indoor air conditioning, and the air-conditioning air flow rate and the deviation-corresponding air flow rate are calculated. The larger one of them is controlled as the final blowing amount of the blowing means. Even in this case, since the final blown air amount is equal to or larger than the deviation-corresponding blown air amount, it is possible to increase the heat supply amount to each zone without making a difference in the blowout temperature to each zone. Therefore,
The temperature of each air conditioning zone can be controlled independently regardless of the deviation.

This is a well-known one having M, I / O, etc., and when an engine ignition switch is turned on, power is supplied from a battery (not shown).

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. First, when the automatic control process of the air conditioner is started in step 100, the data is reset (initialized) in step 110. And step 1
At 20, the signals (Tr, Tam, Ts, Te, Tw) obtained by A / D converting the values of the respective sensors 31 to 35 are read, and the set temperature Tset (set by the driver side temperature setter 36a is set. Dr) and the set temperature Tset (Pa) set by the passenger side temperature setter 36b.

Then, in step 130, the target outlet temperature of air conditioning air blown to the driver's seat side (hereinafter referred to as TAO (Dr)) and the target outlet temperature of air conditioning air blown to the passenger seat side (hereinafter referred to as TAO (Pa)) are set. calculate. Specifically, Fig. 4
As shown in, in step 131, TAO (Dr) is calculated based on the following formula 1 stored in the ROM, and in step 132, TAO (Pa) is calculated based on the following formula 2 stored in the ROM. To calculate.

[0030]

[Equation 1] TAO (Dr) = Kset × Tset (Dr) −Kr × T
r−Kam × Tam−Ks × Ts + C

[0031]

(2) TAO (Pa) = Kset × Tset (Pa) −Kr × T
r-Kam * Tam-Ks * Ts + C (Kset, Kr, Kam, Ks are gains and C is a constant for correction) Then, in step 140, the characteristics shown in FIG. ) And TAO (Pa), the driver side required blower voltage VM1 (Dr) and the passenger side required blower voltage VM1 (Pa) are calculated, and the average blower voltage VM1 is calculated.

Specifically, as shown in FIG. 6, first, at step 141, the VM1 (Dr) is calculated from the TAO (Dr) and the characteristics shown in FIG. Then, in step 142, the VM1 is calculated from the TAO (Pa) and the characteristics shown in FIG.
Calculate (Pa). Then, in step 143, the average blower voltage VM1 is calculated based on these VM1 (Dr), VM1 (Pa) and the following formula 3 stored in the ROM.

[0033]

[Formula 3] VM1 = {VM1 (Dr) + VM1 (Pa)} / 2 Next, at step 144, the above Tset (Dr) and Tset (Pa)
Based on the difference (| Tset (Dr) -Tset (Pa) |) and the characteristic of FIG. 7 stored in the ROM, the temperature of the driver's seat and the passenger's seat are controlled independently when the set temperature is the difference. The minimum air volume VM2 required for this is calculated. In addition, this blower voltage V3
Is V1 <V with respect to the blower voltages V1 and V2 shown in FIG.
It is a value satisfying the relation of 3 <V2.

The characteristic of FIG. 7 is that | Tset (Dr) -Tse.
When t (Pa) | <a, VM2 = V1 and a ≦ | Tset (Dr)
−Tset (Pa) | ≦ b when | tset (Dr) −Tset (Pa)
VM2 increases linearly as | increases, and
When Tset (Dr) -Tset (Pa) |> b, VM2 = V3 is set. In this embodiment, the constant a is set to 1 ° C. and the constant b is set to 5 ° C. That is, for example, when Tset (Dr) = 25 ° C. and Tset (Pa) = 26 ° C., VM2 = V1.

In step 145, the above VM1 and VM2 are compared, and the larger one is compared with the blower controller 1
It is calculated as the blower voltage finally applied to 1. Next, at step 150, the above TAO (Dr) and TAO
From (Pa) and the characteristics of FIG. 8 stored in the ROM, the respective blowing modes on the driver side and the passenger side are calculated. Where F
The ACE (face) mode is a mode for blowing out the conditioned air from the face outlet, and the B / L (bi-level) mode is a mode for blowing out the conditioned air from the face outlet and the foot outlet, and a FOOT (foot) mode. Is
In this mode, conditioned air is blown out from the foot outlet.

Then, in step 160, the air mix door 17 is calculated based on the following equation 4 stored in the ROM.
The respective opening degrees SW (Dr) and SW (Pa) of a and 17b are calculated.

[0037]

## EQU4 ## SWi = {(TAOi-Te) / (Tw-Te
)} × 100 (%) (i = (Dr) or (Pa)) Then, in Step 170 to Step 190, the blower controller 11 and the servo are controlled so that the control target value calculated in Step 140 to Step 160 is obtained. The motors 18a, 18b, 25a, 25b are drive-controlled.

According to the above control, in step 145, the larger one of VM1 and VM2 is controlled to become the final blower voltage VM, so that the blower voltage is always VM2 or higher. This VM2 is the minimum air volume required to independently control the temperature of the driver's seat and the passenger's seat when a predetermined set temperature difference (| Tset (Dr) -Tset (Pa) |) exists, and therefore the VM2 is always operated. The amount of air required to independently control the temperature of the seat and the passenger seat is ensured, and as a result, the temperature of the driver's seat and the passenger seat can be controlled independently.

Each step of the flow charts shown in FIGS. 3, 4 and 6 constitutes means for realizing each function. (Other Embodiments) In the above embodiment, VM2 is calculated based on the difference in set temperature as shown in FIG. 7, but VM2 is calculated as shown in FIG. 7 based on the difference in target outlet temperature of each seat. May be calculated. In other words, the fact that the target blowout temperature is different for each seat means that the heat supply amount for each seat is different, and in this case as well, when the difference in the target blowout temperature is large, the seat with the larger blowout air volume is independent of each seat. It becomes easier to control the temperature. Therefore, as in the present embodiment, the larger the difference between the target blowout temperatures is, the larger VM2 is set.
By setting the larger one of 1 and 2 as the final blower voltage, the temperature of the driver's seat and the passenger's seat can always be controlled independently as in the first embodiment.

As another example, VM2 may be calculated as shown in FIG. 7 based on the difference between the output values of the two surfaces of the solar radiation sensor 33. That is, the fact that the output values of the respective surfaces are different means that the heat load due to solar radiation differs between the driver's seat and the passenger's seat, and the blowout temperatures must be made different. Therefore, in this case as well, since the amount of heat supplied to each seat is different, the VM2 is set to be larger as the difference between the output values of the respective surfaces is larger,
By setting the larger one of VM2 and VM1 as the final blower voltage, the temperature of the driver's seat and the passenger's seat can always be controlled independently.

Further, VM2 may be calculated based on the difference in the blowing mode of each seat. That is, since the blowout temperature generally increases in the order of face mode → bilevel mode → foot mode, the blowout temperature also differs if the blowout mode is different. Therefore, if the blowout mode is different, the amount of heat supplied to each seat is also different. Therefore, also in this case, the temperature of the driver's seat and the passenger's seat can always be controlled independently by setting the VM2 according to the difference in the blowing modes and setting the larger one of the VM2 and the VM1 as the final blower voltage.
