<1. First Embodiment> FIG. 1 is a diagram showing an example of a configuration of an in-store temperature control system 100 according to a first embodiment. In FIG. 1, the area indicated by the two-dot chain line indicates the store 1.

As shown in FIG. 1, the in-store temperature control system 100 comprises an air conditioner 10 and a case temperature controller 2.

In the air conditioner 10, the outdoor unit 19, the plurality of indoor units 11 to 13, and the heat exchanger 18 are connected by a communication line 10a so that data communication is possible. The heat exchanger 18 has a ventilation function for ventilating the air in the store 1 in addition to the heat exchange function.

A plurality of open-type showcases (hereinafter simply referred to as showcases) 21 and 22 which are arranged in the store 1 and are not provided with a door for sealing cool air are provided in the case 1. It is constituted by the outdoor unit 29 and can cool the inside of each of the showcases 21 and 22 to an individual set temperature, and can freeze or refrigerate articles such as merchandise stored in each of the showcases 21 and 22. It has become. The case temperature controller 20 is also used for the outdoor unit 2.
9 and the plurality of showcases 21 and 22 are connected to the communication line 20.
a for data communication.

The centralized controller 30 is configured to be able to perform data communication with the outdoor unit 19 of the air conditioner 10 and the outdoor unit 29 of the in-case temperature controller 20 via the communication line 30a. Therefore, the centralized controller 30

For example, in addition to the normal cooling operation,
There are an energy saving operation mode, a capacity limitation operation mode, a defrost operation mode, and the like, and also includes a stopped state. Then, the showcase monitoring unit 33 determines what kind of operating state the operating state of each of the showcases 21 and 22 is.

Further, the leak cool air judging section 32 judges whether each of the showcases 21 and
The amount of leaked cool air is determined in accordance with the operation state of Step 22. For example, if each of the showcases 21 and 22 is in a normal cooling operation, it can be determined that there is a lot of leaked cool air, while the cooling operation is stopped or is operating in another operation mode. In this case, it can be determined that little or no leakage cool air is generated. The result of the judgment in the leak cool air judging section 32 is the air conditioner control section 31.
Is transmitted to

The air conditioner control unit 31 controls the operation of the air conditioner 10 according to the result of the judgment by the leaked cool air judgment unit 32. The air conditioner control unit 31 includes a plurality of indoor units 11 to
13 can be individually controlled, and the operation of the outdoor unit 19 and the heat exchanger 18 can also be controlled.

Each of the showcases 21 and 22 of the in-case temperature controller 20 includes a CPU (not shown) and the like, and the CPU operates based on a set temperature set according to the articles housed therein. Operation control is performed to perform the cooling operation. Further, the CPU notifies the centralized controller 30 of the operating state of the showcase as a predetermined control signal via the communication line 20a. Note that the CPU may send a trigger indicating the operation change to the centralized controller 30 when the operation change is performed in each showcase.

In the in-store temperature control system 100 having the above-described configuration, the in-case temperature controller 20 controls the temperature of each of the showcases 21 and 22 even when there is a large amount of cold air leaking from each of the showcases 21 and 22. The set temperature cannot be changed. This is because the set temperature of each of the showcases 21 and 22 is determined according to the stored articles, and changing the set temperature leads to a factor that deteriorates the storage state of the articles.

Therefore, in this embodiment, the centralized controller 30 determines the degree of the leaked cold air according to the operating condition of each of the showcases 21 and 22 obtained via the communication lines 20a and 30a, and determines the influence of the leaked cold air. The operation of the air conditioner 10 is controlled so as to reduce the pressure. That is, in the in-store temperature control system 100, the showcases 21 and
2 is a signal relating to the operating condition is sent to the air conditioner 10 side, and the showcases 21 and 22 are operating.
For example, when the air conditioner 10 is in the cooling operation, the influence of the leaked cool air is reduced by lowering the cooling capacity of the air conditioner 10.

The control for reducing the influence of the leaked cool air is different depending on whether the air conditioner 10 is performing the cooling operation or the heating operation.

First, the operation control when the air conditioner 10 is performing the cooling operation will be described.

When the centralized controller 30 determines that there is a large amount of leaked cool air, it stops the cooling operation, increases the set temperature, and changes the wind direction upward from the steady operation state for the cooling operation based on the predetermined set value. By taking measures such as reducing the air volume, switching the operation mode from the cooling operation to the air blowing operation, or setting the ventilation operation by the heat exchanger 18 to the operating state, the countermeasures against the leaked cold air are performed.

If the cooling operation is stopped (), the temperature drop near the showcases 21 and 22 can be suppressed. Further, by raising the set temperature (), the temperature of the air blown out from the indoor units 11 to 13 can be increased, and the phenomenon of lowering the temperature near the showcases 21 and 22 can be suppressed. In addition, when the wind direction is changed to the upward direction (), since the cool air does not directly hit the consumer, it is possible to suppress the consumer from feeling the cold near the showcase. Also, by reducing the air volume (), it is possible to reduce the amount of cold air felt by the consumer, so that it is possible to suppress the consumer from feeling cold. Also, by switching the operation mode from the cooling operation to the ventilation operation (),
Since it is possible to prevent the cool air from being blown out, it is possible to reduce a consumer's feeling of cold. Furthermore, by performing the ventilation operation (), it is possible to circulate the cool air leaking from each of the showcases 21 and 22,
Leakage cold air can be prevented from staying near the showcase.

In any of the above cases,
It is possible to reduce a consumer's feeling of cold due to the leaked cold air, and it is possible to prolong the residence time of the consumer near the showcases 21 and 22. In any of the above measures, the cooling capacity of the air conditioner 10 due to the cooling operation is reduced.
If the air is circulated through the air conditioner, the inside of the store 1 can be set to a predetermined set temperature, so that the air conditioner 10 can save energy in the cooling operation.

Next, operation control when the air conditioner 10 is in the heating operation will be described.

When the centralized controller 30 determines that there is a large amount of leaked cold air, the heating operation is continued, the set temperature is increased, and the wind direction is changed downward from the steady operation state for the heating operation based on the predetermined set value. , The air flow is increased, or the ventilation operation by the heat exchanger 18 is set to the operation state, thereby coping with the leakage cold air.

If the heating operation is continued (), the influence of the leaked cool air from the showcases 21 and 22 can be suppressed, and the lowering of the temperature near the showcase can be suppressed. In addition, by raising the set temperature (), the temperature of the air blown out from the indoor units 11 to 13 can be increased, and the lowering of the temperature in the vicinity of the showcases 21 and 22 can be suppressed. Also, if you change the wind direction to down (), direct warm air to the consumer,
The influence of the cool air leaking from the showcases 21 and 22 can be reduced, and the consumer can be prevented from feeling cold near the showcase. In addition, the effect of the leaked cold air can be reduced by increasing the air volume (). Further, by performing the ventilation operation (), it is possible to circulate the leaked cool air from each of the showcases 21 and 22, and it is possible to suppress the leak cool air from staying near the showcase.

In any of the above cases,
When it is determined that there is a lot of leaked cool air, the temperature in the store that has been lowered by the leak cool air can be increased,
It is possible to reduce a consumer's feeling of cold due to cold air leaking from the showcases 21 and 22. And
It is possible to extend the residence time of the consumer near the showcases 21 and 22.

On the other hand, if the centralized controller 30 determines that no cool air leakage has occurred or is relatively small, it is not necessary to take any special measures against the cool air leakage. For this reason, when the countermeasures against the leaked cold air as described above are performed, by returning to the steady operation state, the cooling operation or the heating operation based on the predetermined set value can be performed, and the in-store 1 is set to the set temperature. Can be maintained.

When the centralized controller 30 controls the air conditioner 10 according to the leaked cold air, it may be possible to perform air conditioning control on all the indoor units 11 to 13.
If there is an effect of the leaked cool air only in a local portion of the store 1, only the indoor units that can exert an air-conditioning effect on the local portion may be controlled. By doing so, showcase 2 in store 1
It is possible to reduce the local influence of the leaked cool air from the air conditioners 1 and 22, and to maintain the steady operation state of the air conditioner 10 in another part of the store.
For this reason, the air-conditioning operation based on the set value can be performed in a portion not affected by the leaked cool air. For example, when the indoor unit 12 is located above the showcases 21 and 22 and the indoor units 11 and 13 are separated from the indoor unit 12,
Only the indoor unit 12 is controlled as described above.

As described above, in this embodiment, the centralized controller 30 that controls the air conditioner 10 and the in-case temperature controller 20 comprehensively operates the showcases 21 and 22 and controls the air conditioner 10. , The air conditioner 10 can be operated so as to reduce the influence of the cooling air leaking from the showcases 21 and 22.

In this embodiment, the centralized controller 30 is configured to judge the amount of leaked cold air in accordance with the operating conditions of each of the showcases 21 and 22 and to control the operation of the air conditioner 10. Therefore, when the operating condition of each of the showcases 21 and 22 is an operating condition that causes a cool air leak, the air conditioner 10 is configured to reduce the influence of the leaking cool air from the showcases 21 and 22.
Can be operated.

The leaked cool air judging section 32 judges whether each of the showcases 21 and 21 recognized by the temperature sensor
The degree of the leaked cool air is determined in accordance with the temperature distribution in the vicinity of position 2. For example, if the detected temperature is lower than the set temperature for the air conditioner 10, it can be determined that there is a large amount of leaked cool air. On the other hand, if the detected temperature is equal to or higher than the set temperature, Can be determined to be small or not generated at all. The result of the judgment in the leaked cold air judging section 32 is transmitted to the air conditioner control section 31.

The air conditioner control unit 31 controls the operation of the air conditioner 10 according to the result of the judgment by the leaked cold air judgment unit 32. Also in this embodiment, the air conditioner control unit 31 can individually control the operation of the plurality of indoor units 11 to 13 and can also control the operation of the outdoor unit 19 and the heat exchanger 18. It has become.

As described above, the centralized controller 30 can detect the temperature of the place where each of the temperature sensors 42a to 42c is installed in the vicinity of each of the showcases 21 and 22. The impact can be recognized.

Then, as described in the first embodiment, the centralized controller 30 controls the temperature sensors 42a-42
If the operation control of the air conditioner 10 is performed in accordance with the temperature detected by c, it is possible to reduce the influence of the leaked cool air.

When the centralized controller 30 controls the operation of all the indoor units 11 to 13 collectively, the centralized controller 30 does not need to identify the installation location of each of the temperature sensors 42a to 42c. However, when the centralized controller 30 individually controls the operation of each of the indoor units 11 to 13 according to the temperature signals from the temperature sensors 42a to 42c, it is necessary to recognize which of the indoor units should be controlled. For this reason, it is necessary to identify the installation location of each of the temperature sensors 42a to 42c in the centralized controller 30.

Therefore, in this embodiment, the centralized controller 30 is made to previously store information on the installation location of each of the temperature sensors 42a to 42c, and the air conditioner controller 31 of the centralized controller 30 has It is configured such that an indoor unit that can be air-conditioned for a specific place can be specified.

That is, the leaked cold air judging section 32 of the centralized controller 30 specifies a temperature sensor that detects a temperature lower than the set temperature of the air conditioner 10 among the plurality of temperature sensors 42a to 42c. Then, the air conditioner control unit 31 specifies an indoor unit capable of air-conditioning the installation location of the specified temperature sensor. Then, by controlling the operation of the specified indoor unit so as to reduce the influence of the leaked cool air on a local place that is in a low temperature state due to the influence of the leaked cool air, the vicinity of the specified temperature sensor is reduced. This will increase the temperature.

As described above, in the present embodiment, the centralized controller 30 for controlling the air conditioner 10 and the in-case temperature controller 20 in a comprehensive manner is provided by the temperature sensors 42a to 42a installed near the showcase. Since the configuration is such that the degree of cold air leakage is determined in accordance with the temperature detected by 42c and the operation control of the air conditioner 10 is performed, each of the showcases 21 and 22 generates cold air leakage and lowers the ambient temperature. In such a case, the air conditioner 10 can be operated so as to reduce the influence of the cool air leaking from the showcases 21 and 22. Therefore, it is possible to avoid the consumer 8 from feeling cold due to the influence of the leaked cold air at the positions near the showcases 21 and 22, and the showcases 21 and 22 of the consumer 8 can be avoided.
The residence time at a position near the can be lengthened.

When the centralized controller 30 determines that no cold air leakage has occurred or is relatively small, the centralized controller 30 sets the air conditioner 10 in a steady operation state to set it to a predetermined set value. A cooling operation or a heating operation based on the above is performed. This is because in this case, it is not necessary to take measures against the leaked cool air.

The control mode in this embodiment may be used together with the control mode in the first embodiment.

<3. Modifications> Several embodiments of the present invention have been described above, but the present invention is not limited to the above description.

For example, in the above description, an example in which the centralized controller 30 has a function of controlling the air conditioner 10 in accordance with the cold air leaking from each of the showcases 21 and 22 has been described, but the present invention is not limited to this.
