多くの提案が行われている。2. Description of the Related Art Generally, a variable air volume air conditioner, especially V
In the AV air conditioning system, the opening of the VAV unit becomes smaller as the room temperature of the air-conditioned room approaches the set value, and the amount of air supplied from the air conditioner to the air-conditioned room is reduced to secure the required outside air amount. It will not be done. Therefore, the required outside air amount in the air-conditioned room is not satisfied, and as a result, the indoor environment may be deteriorated. In order to solve this point, many proposals have been made in the past.

There is a device in which the air conditioner is controlled according to the blown air supply amount of the air conditioner (JP-A-2-29533) (hereinafter, simply referred to as Conventional Example 1).

A CO 2 concentration meter that measures the CO 2 concentration of air, and the minimum opening value of the air volume control valve in the variable air volume unit is corrected by the CO 2 concentration measurement value by the CO 2 concentration meter (Japanese Patent Laid-Open No. 2- 233933 publication) (hereinafter, simply referred to as Conventional Example 2).

ある(以下、単に従来例3と記す)。Further, even in one of the plurality of variable air supply amount adjusting means and the air-conditioned room, the load status is controlled according to the load status of each air-conditioned room. If the load condition exceeds the predetermined load reset deviation, the load reset means is provided to return the load condition that falls into the load reset deviation to the unsatisfied load condition by increasing the capacity of the air supply air temperature of the air conditioner. In the above device, the load condition returned to the load reset deviation is brought close to the load reset deviation while reducing the capacity of the blow-off air supply temperature, and the air supply to each air-conditioned room is performed by the variable air supply amount adjusting means. There is one that attempts to secure the return air amount by suppressing the decrease in the blowout amount (Japanese Patent Laid-Open No. 2-44141) (hereinafter, simply referred to as Conventional Example 3).

不可能である。In the prior art example 1, the outside air intake amount for the return air is changed according to the total blown air supply amount of the air conditioner. That is, when the total blown air supply amount of the air conditioner decreases, the outside air intake amount is increased to increase the ratio of the contained outside air, thereby compensating for the shortage of the absolute amount of outside air in the air-conditioned room. Therefore, a method for improving the environmental deterioration of the air-conditioned room has been proposed. However, Conventional Example 1 does not show how to determine the ratio of the contained outside air with respect to the total air supply amount of the air conditioner. That is, in a normal VAV air-conditioning system, there are a plurality of air-conditioned rooms, and even if the ratio of the contained outside air to the total air supply amount of the air conditioner is determined, the required outside air intake of all the air-conditioned rooms The quantity cannot be satisfied. Further, in Conventional Example 1, the ratio of the contained outside air to the total air supply amount of the air conditioner is determined, but the control of the outside air intake amount shown in the specification is merely performed by the outside air intake damper. It is practically impossible to control the outside air intake amount effectively only by adjusting the opening degree.

量を確保することは不可能である。In Conventional Example 2, a CO 2 concentration meter for measuring the CO 2 concentration of the air exhausted from the room, and an air volume control valve (in the variable air volume unit) based on the CO 2 concentration measurement value by the CO 2 concentration meter ( A method for correcting the value of the minimum opening degree of the VAV damper) is presented. In this method, when the amount of air supplied from the air conditioner to the air-conditioned room is reduced and the required outside air volume is not secured, the air-conditioning is performed in order to minimize the decrease in the intake amount of the air-conditioned room. This is a method of increasing the lower limit of the amount of air supplied from the machine to the air-conditioned room. However, with this method, the controllability of the room temperature is completely lost.
Further, it is impossible to secure the required outside air amount by raising the lower limit of the air supply amount to some extent.

の提案が行われている。On the other hand, as is apparent from the above-mentioned conventional example 2, if the amount of air supplied from the air conditioner to the air-conditioned room is increased for the purpose of securing the amount of outside air, the room temperature of the air-conditioned room will increase. Control is often impossible. Many proposals have been made in this regard as well.

て還気量を確保しようとするものである。For example, in Conventional Example 3, one of a plurality of variable air supply amount adjusting means for controlling the amount of air supplied to each air-conditioned room according to the load condition of each air-conditioned room and one of the air-conditioned rooms. Even if the load condition falls into a dissatisfied state that exceeds a preset load reset deviation, the load condition is returned to within the load reset deviation by increasing the capacity of the air supply air temperature of the air conditioner. In a device provided with a reset means, the load condition returned within the load reset deviation is brought close to the load reset deviation while reducing the capacity of the blown air supply temperature, and the air-conditioned room is controlled by the variable air supply amount adjusting means. It aims to secure the return air volume by suppressing the decrease in the supply air volume to each unit.

乏しい。That is, in the conventional example 3, the room temperature of the air-conditioned room approaches a set value, the amount of air supplied from the air conditioner to the air-conditioned room (= return air quantity) decreases, and the required outside air quantity is reduced. In order to prevent that the supply air temperature is not secured (for example, in heating, reduce the supply air temperature)
As a result, the air supply amount (= return air amount) to the air-conditioned room is to be secured. This method is a comparatively effective method that has been performed conventionally, but in reality, it lacks compensation to secure the supply air amount (= return air amount) to the air-conditioned room.

FIG. 3 is a correlation diagram showing the relationship between the preset difference between the preset temperature and the room temperature, the air flow rate, and the outside air ratio. As shown in FIG. 3, when the difference between the set temperature and the room temperature is large, the air flow rate is large, and as the difference between the set temperature and the room temperature is small, the air flow rate is controlled to be small. Furthermore, by setting the set maximum air volume Q MAX and the set minimum air volume Q MIN to determine the maximum and minimum values of the air flow rate, the air flow rate does not exceed the set maximum air flow rate Q MAX even if the temperature difference becomes large. Even if the difference becomes small, the air flow rate is controlled so as not to exceed the set minimum air flow rate Q MIN . Here, even if the room temperature or the air flow rate changes, the air-conditioned room needs a certain amount of outside air (required outside air amount).

If it is 10 [%] of MAX , the outside air ratio [%] of the blown air amount Q i of each air-conditioned room is Q MAX × 0.1 / Q i × 100. Therefore, for example, if the set minimum air volume Q MIN is half of the set maximum air volume Q MAX , the outside air ratio in this case is 20%. In this way, the outside air ratio is determined based on the value of the air flow rate of each air conditioning chamber. That is, in other words, the outside air ratio corresponds to the air flow rate determined by the heat load of each air-conditioned room,
It will be required for each air-conditioned room. Furthermore, by selecting the largest of the outside air proportions,
At least in all the air-conditioned rooms, the required outside air volume is secured regardless of the room temperature and the air flow rate.

The introduced outside air amount is controlled based on the outside air amount as in the first embodiment. Therefore, the amount of air blown into the air-conditioned room increases to the rated maximum value, and the outside air ratio becomes a predetermined maximum ratio, so that the amount of outside air introduced into the air-conditioned room becomes maximum. Further, at that time, since the exhaust damper 35 installed in the air-conditioned room is opened, most of the contaminated air such as gas or dust in the air-conditioned room is released to the outside through the exhaust damper 35. Since the ratio of returning to the return port 10 of the indoor unit 2 and recirculating is extremely small, the effective ventilation amount of the air-conditioned room is increased and the diffusion of polluted air to other air-conditioned rooms is minimized. ..

Based on this information, the heat supply control means 37 determines the heat load satisfaction status of each air-conditioned room (step S7). Subsequently, in step S8, it is determined whether or not the room temperature of all the air-conditioned rooms has reached the set value (whether the heat supply of all the air-conditioned rooms is sufficient). That is, when the room temperature of all the air-conditioned rooms has reached the set value, the process branches to step S9 to stop the heat source device 14 and to perform the heat conversion operation in the heat exchanger 3 provided in the indoor unit 2.

(Whether the heat supply to all the air-conditioned rooms is not sufficient) is determined. If it is determined in step S10 that the heat supply to all the air-conditioned rooms is not sufficient, the process returns to step S6.

The control of the new blowout temperature is performed in order to minimize the deviation of the temperature of the air-conditioned room in which the heat supply is satisfied from the set value. As described above, normally, the heat source unit 14
