This is a control signal feedback circuit for stabilizing the opening degree of No. 2. In FIG. 2, each evaporator 9, 10 is connected in parallel to a compressor 29, a capacitor 30, and a liquid tank 31 via operating valves 25, 26 and expansion valves 27, 28. In such a cooling cycle, the evaporator 9 or 1 is opened by opening either or both of the operation valves 25 and 26.

Cooling medium is supplied to one or both of the evaporators 9 and 10 by opening and closing the evaporators 5 and 26. Therefore, a pressure fluctuation occurs in the cooling cycle, and a difference occurs in the evaporation capacity of each evaporator 9, 10. For this reason, the air blowing temperature fluctuates transiently when the operation is switched. Figure 4 is an air outlet temperature characteristic diagram showing this relationship. During time t1 when the air conditioner unit is used alone, the steady temperature is
C 1 , but when the other side of the air conditioner unit is turned on, the temperature will decrease for the first t 2 hours after switching on.
The temperature rises transiently to c 2 , but then returns to the steady temperature c 3 within t 3 hours. And this temperature c 3 > c 1
Therefore, compared to the case where only one air conditioner unit is used, the cooling efficiency decreases when both are used. Furthermore, if the air conditioner unit is switched to standalone use after t 3 hours, the outlet temperature will drop to c 4 at t 4 hours.
It drops sharply to c 1, but then settles to c 1 .

る。 The present invention was developed in view of this problem, and uses a timer function to automatically adjust the opening degree of the air mix door according to the operating status of one or both of the air conditioner units, and the time during which the air outlet temperature changes transiently. Therefore, it is an object of the present invention to provide an air conditioner for an automobile, which corrects sudden changes in air outlet temperature and eliminates the discomfort of occupants.

る。 FIG. 5 shows a control system for an air conditioner according to the present invention. The difference between this and the one shown in FIG. 3 is that between the blowout temperature setter 22 and the opening degree setter 23 of the air mix doors 11 and 12, the blowout amount is set so that the blowout temperature of the air is at a predetermined stable level. A calculator 32 is connected which has a timer function to automatically adjust the time for a predetermined period of time.
An operation state detector 33 as a detection means for detecting that the air conditioner unit is switched to single operation or both operations and outputs a switching signal is connected to the computing unit 32 as this outlet temperature compensating means.

快感を覚えるといつた従来の欠点が改善される。 On the other hand, as shown in FIG. 6a, the arithmetic unit 32 receives a signal for adjusting the opening of the air mix doors 11, 12 from a switching signal from the operating state detector 33 when the air conditioner unit is used alone or when both are used. and outputs it to the opening setting device 23. The correction signal for adjusting the opening degree is predetermined based on the blowout temperature that changes over time in an analog manner immediately after the evaporators 9 and 10 shown in FIG. 6b, and the correction signal shown in FIG. A relative level signal as shown is used. Therefore, when the air conditioner unit is switched from single operation to both operation, or vice versa, the evaporator at time t 2 and time t 4 shown in FIG. By inputting the correction signal shown in FIG. 7 to the opening degree setting device 23, the air mix doors 11 and 12 are adjusted to wide open or close respectively to adjust the sudden change in the blowout temperature of 9 and 10. The outlet temperature of the evaporators 9 and 10 in the steady state at t 1 hour and t 3 hours shown in FIG. 6b is also adjusted to a constant temperature using the correction signal shown in FIG. 7. can. Thus,
The air outlet temperature as an air conditioner unit can be maintained almost as desired as shown in Figure 6c by absorbing the fluctuations in the outlet temperature immediately after the evaporators 9 and 10 over the entire time period by adjusting the opening degrees of the air mix doors 11 and 12. This makes it possible to maintain a stable air outlet temperature from the air conditioner unit. In this way, the conventional drawback of causing discomfort due to changes in room temperature due to switching of the air conditioner unit can be improved.

ある。 As explained above, there is a detection means for detecting that the operation of the front seat air conditioner unit and the rear seat air conditioner unit have been switched, and the time period during which the evaporator outlet temperature changes at least transiently depending on the switching state. By providing a blowout temperature compensation means that outputs a signal to automatically adjust the opening degree of the air mix door and compensates for the blowout temperature of the air conditioner unit to a substantially constant value, changes in the blowout temperature caused by the above switching of the air conditioner unit can be suppressed. This can be suppressed as much as possible, and the discomfort felt by the occupant due to fluctuations in the air outlet temperature can be eliminated. In addition, since the configuration is such that only the arithmetic unit 32 and the operating state detector 33 are added to the conventional circuit, there is an advantage that it can be obtained easily and at low cost.
