転を禁止してしまう場合があることである。 Conventionally, this type of air conditioner has a configuration as shown in FIG. 1, for example. Although FIG. 1 shows a system having three indoor units, a system having two or more indoor units has a similar configuration. 1 is an outdoor unit, which includes a variable capacity compressor 1A, an outdoor heat exchanger 1B, a fan motor 1C, and solenoid valves 1D to 1F. The capacity of the air conditioner is to control the capacity of the compressor 1A,
The electromagnetic valves 1D to 1F, which serve as refrigerant flow rate control means, are controlled on and off as appropriate to control the overall capacity.
Indoor units 2, 3, and 4 each have an indoor heat exchanger 2.
B, 3B, 4B, fan motor 2C, 3C, 4
C, has capillary tubes 2G, 3G, and 4G. Although the air conditioner shown in FIG. 1 is of a cooling-only type, this is just a limitation to facilitate the explanation of the present invention, and the present invention is not limited to a cooling-only type, but a cooling/heating type. , cold dry type, cool/warm dry type, etc. In such a configuration, the operation is explained below. When a specific indoor unit is operating, in any case, the operation of other indoor units is prohibited, or if there are multiple other indoor units In this case, the other indoor units perform switching operation.
In other words, the number of operating indoor units is limited in advance. The biggest drawback of this method is that the total air conditioning load is not detected, so even if all indoor units are operating within the capacity of the air conditioner, if there is surplus capacity, operation of indoor units may be prohibited unnecessarily. There are cases where this happens.

The air-conditioning state detecting means is installed in the room and detects the air-conditioning state of the space air-conditioned by each indoor unit, and a typical example thereof is a thermistor that converts the temperature of the space into a resistance value. Although the thermistor is provided inside the indoor unit here, it may be located outside the indoor unit as long as it is located outside the indoor unit and can detect the air conditioning condition. 6 is a priority space that specifies a space that will be air-conditioned preferentially to the specified state, that is, the best air-conditioning state, even in cases where the total air-conditioning load exceeds the air-conditioning capacity. This is a switch as a means of selection. 5 is thermistor 2T,
3T, 4T, and the switch 6 as inputs, this is a control circuit that outputs a capacity control signal for the variable capacity compressor 1 and a signal for turning on and off the solenoid valves 1D to 1F. A specific one of the outputs of the thermistors 2T to 4T is selected by the analog multiplexer 5M, and the output is
It is converted into a digital quantity by a D converter 5A and inputted to a microcomputer (hereinafter abbreviated as microcomputer) 5P. The output of the switch 6 is directly input to the microcomputer 5P. In microcontroller 5P, thermistor 2T
The current air conditioning state of each space is determined based on the space temperature detected by ~4T and past temperature data stored in the microcomputer 5P. Here, air conditioning status refers to, for example, temperature, whether each room temperature is within the set temperature range or not, and even if it is not currently in the temperature range, whether the temperature is decreasing and whether it will be in the future. It can be determined based on current and past temperature data. The air conditioning criterion setting means for providing such criteria for determining the air conditioning condition can be provided in advance in the microcomputer 5P, or the microcomputer 5P can be provided with an appropriate air conditioning condition criterion setting means 7, for example, multiple contacts, from the outside. With the switch, each contact point can be associated with a temperature, and a desired air conditioning state can be input to the microcomputer 5P using the contact point specified by the switch.

適性を或る程度保つものである。 Now, the space specified by switch 6 (in the figure, it is at contact point 62, so space 3 corresponding to indoor unit 3)
Suppose that the air conditioning load of R) increases and exceeds the air conditioning capacity. Then, the temperature of the space tends to rise, and the temperature is detected by the thermistor 3T, and the microcomputer 5P recognizes that the air conditioning state of the space 3R is the best air conditioning state, which is far from the set temperature range. As a result, first of all, a signal is output that increases the capacity of the compressor 1A, and the capacity controller 5V, for example, the compressor 1A
If the compressor has two speeds, high and low, the speed switch uses the signal to increase the capacity of the compressor 1A, thereby increasing the cooling capacity. Even if compressor 1A reaches its maximum capacity by performing such operations, if the air conditioning condition of space 3R is not the best, then
In order to stop the cooling operation of the indoor unit corresponding to the space in the best condition among R and 4R (spaces corresponding to indoor units 2 and 4, respectively), the corresponding solenoid valve 1D or 1F is turned off. The timing of turning on and off these solenoid valves is controlled based on so-called time division. That is, the microcomputer 5P controls the solenoid valve 1D and the solenoid valve 1 based on predetermined timing.
F is turned on and off alternately at predetermined time intervals. By doing this, it is possible to avoid permanently stopping the cooling operation of the spaces 2R and 4R corresponding to the solenoid valves 1D and 1F, and the cooling capacity is approximately halved compared to when the solenoid valves are kept on. Although it decreases, it does not go to zero, so a certain level of comfort can be maintained. on the other hand,
Since the cooling capacity of the indoor unit 3 is increased by the equally divided operation of the solenoid valves 1D and 1F, the priority space 3R is in the best air conditioned state. If this best condition is obtained, the above-mentioned priority operation is canceled again and the normal operation mode, that is, simultaneous cooling of three spaces, is performed. As described above, the control device consisting of the thermistor, switch, and control circuit is
It controls the solenoid valves 1D and 1F in a time-sharing manner as appropriate so that the space selected by the switch 6 is given priority and always has the best air conditioning condition, thereby maintaining a certain degree of comfort in non-priority spaces. It is.

果が得られる。 In the above description, a thermistor is used as the air conditioning state detection means, but other temperature sensors such as platinum wires may be used, and not only temperature sensors but also humidity sensors and the like may be used. Further, in the embodiment, only one priority space can be designated, but depending on the air conditioning function, etc., it is possible to designate a plurality of spaces. Further, although the capacity of the compressor is variable, even if a single capacity compressor is used, the gist of the present invention is not affected and the same results can be obtained.

D,1Fの開閉状態を示す。 The present invention will be explained in more detail using the operation timing chart shown in FIG. In the same figure, A indicates the temperature.
In the figure, the solid line T 3 is the space temperature of the priority space 3R, the two-dot chain line T 2 is the temperature of the space 2R, and the one-dot chain line T 4 is the space temperature of the space 4R.
T r1 and T r2 indicate the set temperatures set by the air conditioning criterion setting means 7. If the temperature is between T r1 and T r2 , the space will be in a comfortable state. Although T r1 and T r2 can be set separately for each space, in this example, the temperature of each space is normalized to T r1 . That is, each space temperature T' and each reference temperature T r12 , T r13 , T 14
It is shown in the form of the temperature difference between T r2 has a constant temperature difference with respect to T r1 , and there is no difference for each space. Figure 3 B, C and D are solenoid valves 1E and 1, respectively.

1Dを閉じる。 Cooling operation for three spaces has been performed since time T 0 .
Here, the temperature T 3 of the priority space 3R is on the rise, and moreover, it is on the move away from the comfort zone. Therefore, at time t1 , the need for priority control is recognized by the microcomputer 5P, and the priority control operation mode is entered. That is, at this point, T 2 >T 4 , so the solenoid valve 1D corresponding to the space 4R is closed, two-space operation is performed, and the cooling capacity per space is increased. As a result, the capacity that had been consumed in space 4R until now is allocated to spaces 2 and 3, and T 2 ,
T 3 takes a downward trend. When a predetermined time Δt has elapsed (time t 2 ), the microcomputer 5P opens the solenoid valve 1D and closes the solenoid valve 1F in order to switch the cooling operation of the non-priority space. As a result, the temperature of space 4R
T 4 is a downward trend and T 2 is an upward trend. After Δt has elapsed from time t 2 , the opening/closing relationship of the solenoid valves 1D and 1F is reversed. The timer for Δt inside the microcomputer 5P is triggered again at time t 3 and the timer (t 3 + Δt)
Then, the opening/closing relationship of the solenoid valves 1D and 1F is attempted to be reversed again. However, before the time (t 3 +Δt) is reached, the temperature T 3 of the priority space 3R reaches the temperature T r1 , so at this point the solenoid valve 1E is closed and the cooling operation for this space is stopped. Therefore, there is no longer a need for priority control, and the solenoid valve 1D, which had been closed since time t3 , is opened, and both spaces 2R and 4R enter a cooling operation state, and both space temperatures T2 and T4 decrease. At time t5 , T4 reaches temperature Tr1 , so it is assumed that cooling operation is no longer necessary, and solenoid valve 1D is closed.

永久的冷房運転停止を免がれている。 As described above, while the space designated as the priority space is in the best condition, there is no priority relationship with other spaces, and normal three-room operation is performed. If the air conditioning load becomes large and the air conditioning condition of the designated space deviates from the best condition, time-sharing control of the solenoid valves corresponding to other spaces is performed to avoid a permanent shutdown of cooling operations in other spaces. It's broken.

When a problem occurs, by first turning off the non-priority rooms that are in the best condition, the operation of the farthest rooms can be maintained, so the air conditioning conditions in the non-priority rooms can be kept almost the same, that is, all the rooms can be in almost the same comfortable state. It will be done.
