The air conditioning system according to the present invention will be described below.
<Embodiment 1>
An embodiment of an air conditioning system according to the present invention will be described with reference to the drawings.
<Configuration>
In the present embodiment, an example in which the air conditioning system according to the present invention is provided in a store will be described. In the first embodiment, it is assumed that the store needs to be cooled in a hot season. That is, the outside air temperature outside the store is higher than the room temperature inside the store.

  FIG. 1 is a one-point perspective view of one store equipped with an air conditioning system, and is a partially cutaway perspective view. 2 is a plan view when the store is viewed from the zenith direction, and FIG. 3 is a side view when the store in the state shown in FIG. 1 is viewed from the right side. It should be noted that in the present specification, the drawing showing the configuration of the store 1 describes only the minimum necessary contents for easy viewing of the drawing.

  As shown in FIGS. 1-3, in the air conditioning system which concerns on this invention, the trap part 120 comprised so that it might become one step higher than the other ceiling part in the top part by the side of the door 10 was provided. Since the trap part 120 is configured higher than the other ceiling parts, the higher temperature air stays in comparison with other parts in the store 1 due to the natural law that the higher temperature air rises. Easy structure. In order to obtain a structure in which air having higher temperature stays, the trap portion 120 is desirably provided in a region narrower than the lateral width of the store 1 as viewed from the door 10. As an example, the trap unit 120 can remove a part of the ceiling (ceiling board) and paste the side wall board so as to connect the remaining ceiling board and the ceiling visible by removing the ceiling board. Can be formed.

In the said store, the air conditioner 100 is provided in the ceiling back of the ceiling part comprised one step lower than the trap part 120. FIG.
And the air inlet 101 of the air conditioner 100 is provided so that the trap part 120 may be contact | connected (facing). By carrying out like this, since the air of higher temperature in the store 1 stagnating in the trap part 120 can be sucked and cooled, cooling efficiency becomes high.

  The air conditioner 100 has a function equivalent to that of a general air conditioning facility having a cooling function, and high-temperature air sucked from the air inlet 101 passes through the air conditioner and is cooled. Is sent out from the air outlet 105. In this case, the intake port 101 is configured on the trap unit 120 side, and the blower port 105 is configured on the side opposite to the trap unit 120, so that the high-temperature air in the store 1 collected in the trap unit 120 is not disturbed. Higher temperature air in the store 1 staying in the section 120 can be sucked and cooled.

  A showcase 110 with a cooling function is provided on the back side when viewed from the door 10 of the store 1. Since the showcase 110 with a cooling function needs to keep the temperature of the goods in the warehouse constant, the showcase 110 with the cooling function is arranged in the back of the store 1 rather than the vicinity of the door 10 where a sudden temperature change is predicted. desirable. That is, the reason why the showcase 110 is provided in the back of the store 1 is to minimize the influence of hot air flowing from the entrance / exit. Further, when the showcase 110 is an open case, the air cooled from the upper part of the front face is blown downward to form an air curtain to cool the interior, but cold air is used to reinforce the air curtain. Can be sent out from the air blowing port 105 to enhance the air curtain effect.

The air outlet 105 of the air conditioner 100 is provided above the showcase 110. This is because the temperature of the air around the showcase 110 is lowered by the cool air sent from the air blowing port 105. Thereby, the possibility of causing a situation such as a rapid temperature rise around the showcase 110 can be reduced.
The trap unit 120 is further provided with a temperature sensor 130 and a humidity sensor 140 so as to be in contact therewith, and detects the temperature and humidity of the air staying in the trap unit 120. The detected temperature and humidity are transmitted to the air conditioner 100 and the showcase 110, and are referred to and controlled during processing such as cooling processing.

In FIG. 1, the temperature sensor 130 and the humidity sensor 140 are arranged beside the intake port 101. The location is not limited to the side of the intake port 101, and may be provided so as to be in contact with the trap portion 120.
FIG. 4 is a system diagram schematically showing the system configuration of the air conditioning system. As shown in FIG. 4, the air conditioning system includes an air conditioner 100, a showcase 110, a trap unit 120, a temperature sensor 130, and a humidity sensor 140.

As shown in FIG. 4, the air conditioner 100 is connected so as to be able to communicate with a temperature sensor 130, a humidity sensor 140, and a showcase 110 provided in the trap unit 120. The connection may be a wired connection or a wireless connection.
Moreover, the showcase 110 is connected so that it can communicate with the temperature sensor 130, the humidity sensor 140, and the air conditioner 100 which are provided in the trap part 120. The connection may be a wired connection or a wireless connection.

The temperature sensor 130 is provided in the trap unit 120 and has a function of detecting the temperature of the air in the trap unit 120 and sequentially transmitting the detected temperature to the air conditioner 100 and the showcase 110.
The humidity sensor 140 is provided in the trap unit 120 and has a function of detecting the humidity of the air in the trap unit 120 and sequentially transmitting the detected humidity to the air conditioner 100 and the showcase 110.
FIG. 5 is a simplified diagram of the internal configuration of the air conditioner 100.

The air conditioner 100 is configured such that the air sucked from the air inlet 101 can be sent out from the air outlet 105 through the inside.
As shown in FIG. 5, the air flowing in from the air inlet 101 is cooled by a cooler 103 (also referred to as a cooling coil) after dust and dust in the air are filtered by a filter 102. Then, the cooled air is sent out from the blower port 105 by forming a flow of air as the blower fan 104 rotates. The degree of intake from the air inlet 101 and the degree of delivery from the air outlet 105 are determined by the number of rotations of the blower fan 104. That is, the higher the rotational speed, the higher the intake level and the output level. Moreover, the temperature of the air sent out from the blower port 105 is determined by the degree of cooling by the cooler 103.

FIG. 6 is a block diagram showing a functional configuration of the air conditioner 100.
As shown in FIG. 6, the air conditioner 100 includes a cooler 103, a blower fan 104, a communication unit 601, a storage unit 602, and a control unit 605.
The cooler 103 cools the air that touches the cooler 103 with the refrigerant passing through the inside. Since the control of the degree of cooling (temperature control) is the same as the conventional one, the details are omitted.

  The blower fan 104 has a function of rotating by being driven by a motor in accordance with an instruction from the control unit 605, and cooled air is sent out from the blower opening 105 by the rotation of the blower fan 104. Further, by this rotation, a flow of air inside the air conditioner 100 (flow from the intake port 101 to the blower port 105) is formed. Therefore, the amount of air sucked from the air inlet 101 changes depending on the rotation speed of the blower fan 104.

  The communication unit 601 has a function of performing communication with each device connected to the air conditioner 100. The communication unit 601 receives a signal including information about temperature from the temperature sensor 130, demodulates it, and transmits it to the control unit 605. Further, the communication unit 601 receives a signal including information on humidity from the humidity sensor 140 and transmits the signal to the control unit 605. And the communication part 601 receives the signal which shows operation | movement of the dew prevention heater 112 or the defrost heater 113, and the illuminating device 116 from the showcase 110, and transmits to the control part 605.

The storage unit 602 has a function of storing programs and data required for the operation of the air conditioner 100, such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, HDD (Hard Disc Drive). ) Etc.
The control unit 605 is a processor and has a function of controlling each unit of the air conditioner 100. The control unit 605 has a function of performing the following processes in addition to processes that can be performed by a general air conditioner such as a cooling process and a humidity adjustment process in accordance with the temperature conditions and humidity conditions in the store 1. Have.

The control unit 605 compares the temperature transmitted from the temperature sensor 130 and the humidity transmitted from the humidity sensor 140 with the threshold values set for each, and controls the cooling process according to the comparison result. Has the function to perform.
Specifically, the control unit 605 compares the temperature transmitted from the temperature sensor 130 with a preset threshold value TA1, and also transmits the humidity transmitted from the humidity sensor 140 and the preset threshold value HA1. And compare. When the temperature transmitted from the temperature sensor 130 is equal to or higher than the threshold TA1 and the humidity transmitted from the humidity sensor 140 satisfies the threshold HA1 or higher, the control unit 605 increases the cooling capacity of the air conditioner 100. As a technique for increasing the cooling capacity, it is assumed that a technique conventionally used in an air conditioner is used, and the details thereof are omitted here.

  Further, when the above condition is not satisfied, the control unit 605 compares the temperature transmitted from the temperature sensor 130 with a preset threshold TA2 and the humidity transmitted from the humidity sensor 140 in advance. The set threshold value HA2 is compared. When the temperature transmitted from the temperature sensor 130 is less than the threshold value TA2 and the humidity transmitted from the humidity sensor 140 satisfies the threshold value HA2, the control unit 605 weakens the cooling capacity of the air conditioner 100. As a technique for weakening the cooling capacity, it is assumed that a technique conventionally used in an air conditioner is used, and the details thereof are omitted here.

In addition, the control unit 605 also has a function of increasing the cooling capacity when it is transmitted from the showcase 110 that the dew proof heater 112 or the defrost heater 113 and the lighting device 116 are operated. When the showcase 110 operates the dew-proof heater 112, the defrost heater 113, and the lighting device 116, a heat load is generated on the showcase 110 and the cooling capacity of the showcase 110 is reduced. By cooling more strongly, the cooling capacity of the showcase 110 can be supplemented.
7 is an external view of the showcase 110, and FIG. 8 is a side view of the showcase 110 viewed from the right side in the state shown in FIG. Note that the side view shown in FIG. 8 is a simplified cross-sectional view in order to show the air flow in the showcase 110.

As shown in FIG. 8, the showcase 110 has a cooling function including a cooler 111, a dew proof heater 112, a defrost heater 113, a lighting device 116, a blower fan 117, and a suction fan. It is a showcase.
In the showcase 110, the cooled air is ejected from the discharge port 114. The cooled air ejected from the discharge port 114 prevents the inflow of air having a relatively high temperature from the outside into the chamber by a kind of air curtain effect, and the cooled air circulates in the chamber. The inside of the showcase is cooled and kept at a constant temperature.

As the air ejected from the discharge port 114 goes downward, the air curtain effect is diminished, so that externally high-temperature air tends to flow into the lower side. However, the relatively high temperature air is sucked from the suction port 115, passes through the pipe in the showcase 110, is cooled by touching the cooler 111, and is ejected from the discharge port 114.
FIG. 9 is a block diagram illustrating a functional configuration of the showcase 110.

As shown in FIG. 9, the showcase 110 includes a cooler 111, a dew-proof heater 112, a defrost heater 113, a communication unit 901, a storage unit 902, and a control unit 906.

The dew-proof heater 112 is provided at a place where condensation is likely to occur so as not to deteriorate the appearance when displaying the product in the showcase 110 and so that water droplets due to condensation do not wet the product. Heated to prevent condensation. In FIG. 8, as an example, a case where a metal part around the discharge port 114 is provided with the dew-proof heater 112 is illustrated, but within a range that does not hinder product cooling if it is a place where condensation easily occurs, It can be installed anywhere. The dew proof heater 112 is realized by, for example, a heating wire.

  In the showcase 110, the defrost heater 113 is provided at a location where frost is likely to be generated so that the temperature is not too low and frost is generated, and is appropriately heated by the control unit 906 to generate frost. To prevent. In FIG. 8, as an example, the case where the defrost heater 113 is provided in the vicinity of the suction port 115 where cold air easily hits and frost is likely to be generated and in the vicinity of the cooler 111 where cooling is most likely to occur and frost is illustrated. The defrost heater 113 may be installed anywhere within the range that does not hinder the cooling of the product, as long as the defrost heater 113 is a place where frost is likely to occur. The defrost heater 113 is realized by, for example, a heating wire.

The lighting device 116 has a function of illuminating the interior of the showcase 110. The illumination device 116 is realized by, for example, a fluorescent lamp, an LED, and the like, and the lighting and extinguishing are controlled by the control unit 906. Here, it is assumed that the lighting device 116 includes a plurality of fluorescent lamps or LED bulbs, and can individually control lighting and extinguishing.
The blower fan 117 has a function of passing through the inside of the showcase 110 by the rotation thereof and sending cold air that has been cooled by the cooler 111 from the discharge port 114. The rotation of the blower fan 117 is controlled by the control unit 906.

The suction fan 118 has a function of sucking air to be cooled into the interior of the showcase 110 from the suction port 115 by its rotation. The rotation of the suction fan 118 is controlled by the control unit 906.
An air flow in which air is sucked into the cabinet by the action of the blower fan 117 and the suction fan 118, is cooled by the cooler 111, and cool air for cooling the articles displayed on the product shelf is blown out from the discharge port 114. Is formed.

The communication unit 901 has a function of executing communication with each device connected to the showcase 110.
The storage unit 902 has a function of storing programs and data necessary for the operation of the showcase 110, and is realized by, for example, a RAM, a ROM, a flash memory, an HDD, or the like.

The control unit 906 is a processor and has a function of controlling each unit of the showcase 110. The control unit 906 performs processing that can be executed by the showcase 110 having a general cooling function such as cooling processing and humidity adjustment processing according to the temperature state and humidity state in the cabinet of the showcase 110, in addition to the following. It has a function to execute the process.
The control unit 906 compares the temperature transmitted from the temperature sensor 130 and the humidity transmitted from the humidity sensor 140 with the threshold values set for each, and performs cooling processing and defrosting according to the comparison result. It has a function of performing control of processing, dew prevention processing, and lighting control processing.

First, specific contents of the cooling process will be described. Here, the showcase 110 is described as being capable of three-level control of the cooling degree of the cooler: weak, medium, and strong, but a finer temperature setting may be possible.
The control unit 906 compares the temperature transmitted from the temperature sensor 130 with a preset threshold value T1, and compares the humidity transmitted from the humidity sensor 140 with a preset threshold value H1. When the temperature transmitted from the temperature sensor 130 is equal to or higher than the threshold value T1 and the humidity transmitted from the humidity sensor 140 satisfies the threshold value H1 or higher, the control unit 906 increases the cooling capacity setting value of the showcase 110. Set. This means that the temperature exceeds the threshold value T1 and the humidity exceeds the threshold value H1, which means that the inside of the store 1 is likely to be hot and humid. Therefore, in such a case, in the showcase 110, the cooling processing capability can be strengthened, and the set temperature can be maintained in advance in response to a state where the inside of the store 1 becomes hot and humid.

As a method for controlling the cooling capacity, it is assumed that a technique conventionally used in a showcase with a cooling function is used, and the details thereof are omitted here.
In addition, when the above condition is not satisfied, the control unit 605 compares the temperature transmitted from the temperature sensor 130 with a preset threshold value T2, and the humidity transmitted from the humidity sensor 140 in advance. The set threshold value H2 is compared. When the temperature transmitted from the temperature sensor 130 is less than the threshold value T2 and the humidity transmitted from the humidity sensor 140 satisfies the threshold value H2, the control unit 906 sets the cooling capacity of the showcase 110 to be weak.

And the control part 906 sets the cooling capacity of the showcase 110 in the inside, when the temperature and humidity of the trap part 120 do not satisfy | fill the conditions regarding two above-mentioned threshold values T1, T2, H1, and H2.
Next, control of the defrosting process will be described.
Here, it is assumed that the defrosting process is executed at regular intervals, and the interval between the defrosting execution periods can be set to t1 and t2, and t1> t2, that is, t1 is longer than t2. Shall. Here, t2 is an interval of a defrosting execution period that is normally performed in the showcase 110.

  The control unit 906 compares the temperature transmitted from the temperature sensor 130 with a preset threshold value T3, and compares the humidity transmitted from the humidity sensor 140 with a preset threshold value H3. When the temperature transmitted from the temperature sensor 130 is equal to or higher than the threshold value T3 and the humidity transmitted from the humidity sensor 140 satisfies the threshold value H3 or higher, the control unit 906 sets the defrosting interval of the defrosting heater 113 to t1. . In other cases, it is set to t2. This means that if the temperature exceeds the threshold value T3 and the humidity exceeds the threshold value H3, the inside of the store 1 is likely to become hot and humid. In the case 110, since the electric power is turned by the cooling process, it is possible to save energy in the showcase 110 by suppressing the electric power to be used for defrosting (increase the period during which the defrosting is not performed). .

Moreover, when starting the defrosting at the set defrosting interval, the control unit 906 transmits to the air conditioner 100 that the defrosting heater 113 is operated.
Next, the control of the dewproof process will be described.
The control unit 906 compares the temperature transmitted from the temperature sensor 130 with a preset threshold value T4, and compares the humidity transmitted from the humidity sensor 140 with a preset threshold value H4. When the temperature transmitted from the temperature sensor 130 is equal to or higher than the threshold value T4 and the humidity transmitted from the humidity sensor 140 satisfies the threshold value H4 or higher, the possibility that the inside of the store 1 becomes hot and humid increases, and condensation occurs. Therefore, the control unit 906 operates the dew proof heater 112. In other cases, the dew-proof heater 112 is not operated.

In addition, when operating the dew proof heater 112, the control unit 906 transmits to the air conditioner 100 that the dew proof heater 112 is operated.
Finally, the control process of the illumination that illuminates the interior of the showcase 110 will be described.
The control unit 906 compares the temperature transmitted from the temperature sensor 130 with a preset threshold T5, and compares the humidity transmitted from the humidity sensor 140 with a preset threshold H5. When the temperature transmitted from the temperature sensor 130 is equal to or higher than the threshold value T5 and the humidity transmitted from the humidity sensor 140 satisfies the threshold value H5 or higher, the control unit 906 turns off part or all of the lighting device 116. Otherwise, leave it on. This is a configuration for realizing energy saving by increasing the cooling capacity of the showcase 110 when the possibility that the inside of the store 1 becomes hot and humid is high and increasing the power for cooling processing. Further, since the lighting device 116 is also turned on to generate heat, turning off the lighting device 116 can suppress an increase in the internal temperature.
<Operation>
From here, operation | movement of an air conditioning system is demonstrated.

First, operation | movement of the air conditioner 100 is demonstrated using FIG. FIG. 10 is a flowchart showing an operation related to the cooling process of the air conditioner 100.
As shown in FIG. 10, the control unit 605 of the air conditioner 100 measures the temperature and humidity of the air in the trap unit 120 based on the temperature information and the humidity information sequentially transmitted from the temperature sensor 130 and the humidity sensor 140 ( Step S1001).

  The control unit 605 compares the measured temperature and humidity with the threshold value TA1 and the threshold value HA1. As a result of the comparison, if the temperature is equal to or higher than the threshold value TA1 and the humidity is equal to or higher than the threshold value HA1 (YES in step S1002), the inside of the store 1 may be hotter and the humidity may be increased. Increases the cooling capacity of the air conditioner 100 (step S1003).

  When the temperature is not less than the threshold value TA1 and the humidity is not not less than the threshold value HA1 (NO in step S1002), the control unit 605 compares the measured temperature and humidity with the threshold value TA2 and the threshold value HA2 (step S1004). As a result of the comparison, when the temperature is less than the threshold value TA2 and the humidity is less than the threshold value HA2 (YES in step S1004), the temperature in the store 1 is too low. The cooling capacity of the air conditioner 100 is weakened (step S1005).

Next, the control unit 605 detects whether a notification indicating that the defrost heater 113 or the dew proof heater 112 is turned on is received from the showcase 110 (step S1006).
When the ON notification of the defrost heater 113 or the dew proof heater 112 is received from the showcase 110 (YES in step S1006), the control unit 605 increases the cooling capacity of the air conditioner 100. When the notification of ON of the defrost heater 113 or the dew prevention heater 112 is not received from the showcase 110 (NO in step S1006), the control unit 605 maintains the operation state at that time.

The control unit 605 repeatedly executes the process shown in FIG. As a result, the control unit 605 can execute control according to the state of the trap unit 120 and predict how the situation in the store 1 will change thereafter. That is, according to the present embodiment, air having a temperature higher than the room temperature in the store 1 flowing in from the door 10 rises and stays in the trap unit 120 in the store 1 quickly. Therefore, by detecting the temperature change and humidity change of the trap unit 120, it is possible to infer how the store 1 will change in the future, and it is possible to execute control corresponding to the possible change in advance.
Next, the operation of the showcase 110 will be described with reference to FIGS.

FIG. 11 is a flowchart showing operations related to the cooling process of the showcase 110.
The control unit 906 of the showcase 110 measures the temperature and humidity of the air in the trap unit 120 based on the temperature information and humidity information sequentially transmitted from the temperature sensor 130 and the humidity sensor 140 (step S1101).
The control unit 906 compares the measured temperature and humidity with the threshold value T1 and the threshold value H1, respectively. As a result of the comparison, if the temperature is equal to or higher than the threshold value T1 and the humidity is equal to or higher than the threshold value H1 (YES in step S1102), the inside of the store 1 may be hotter and stronger, and is affected. Since the temperature in the cabinet of the showcase 110 may also rise, the control unit 906 sets the cooling capacity of the showcase 110 to be strong (step S1103).

  When the temperature is not less than the threshold value T1 and the humidity is not not less than the threshold value H1 (NO in step S1102), the control unit 906 compares the measured temperature and humidity with the threshold value T2 and the threshold value H2 (step S1105). As a result of the comparison, when the temperature is lower than the threshold value T2 and the humidity is lower than the threshold value H2 (YES in step S1105), the temperature in the store 1 is too low. In this case, Since the quality of the product can be maintained without cooling the showcase 110 so strongly, the control unit 906 sets the cooling capacity of the showcase 110 to be weak (step S1106).

When the temperature is less than the threshold value T2 and the humidity is not less than the threshold value H2 (NO in step S1105), the control unit 906 sets the cooling capacity of the showcase 110 to medium (step S1107).
Then, the showcase 110 performs cooling with the contents set by the control unit 906 (step S1104).

The control unit 906 repeatedly executes the process shown in FIG. Thereby, the showcase 110 can execute control according to the state of the trap unit 120 and predict how the situation in the store 1 will change thereafter.
FIG. 12 is a flowchart showing an operation related to the defrosting process of the showcase 110.

The control unit 906 of the showcase 110 measures the temperature and humidity of the air in the trap unit 120 based on the temperature information and the humidity information sequentially transmitted from the temperature sensor 130 and the humidity sensor 140 (step S1201).
The control unit 906 compares the measured temperature and humidity with the threshold value T3 and the threshold value H3, respectively. As a result of the comparison, if the temperature is equal to or higher than the threshold value T3 and the humidity is equal to or higher than the threshold value H3 (YES in step S1202), the inside of the store 1 may be hotter and the humidity may be increased. Since the temperature in the cabinet of the showcase 110 may also rise, it is necessary to perform cooling. Therefore, in order to turn electric power to the cooling, the control unit 906 performs the defrosting interval by the defrosting heater 113 of the showcase 110. Is set to t1 (step S1203). That is, the interval at which the defrost heater is turned on in the showcase 110 is set to be long.

When the temperature is not less than the threshold value T3 and the humidity is not not less than the threshold value H3 (NO in step S1202), the control unit 906 sets the defrosting interval to t2 (step S1204). That is, the interval at which the defrost heater 113 is turned on in the showcase 110 is set to be shorter than t1.
And the control part 906 turns on the defrost heater 113 according to the set space | interval, and performs defrosting (step S1205).

When the defrost heater 113 is turned on, that is, when the control unit 906 instructs the defrost heater 113 to be turned on (YES in step S1206), the control unit 906 turns on the defrost heater 113. The air conditioner 100 is notified (step S1207).
The control unit 906 repeatedly executes the process shown in FIG. Thereby, the showcase 110 executes control according to the state of the trap unit 120, can execute control that predicts how the situation in the store 1 will change thereafter, and executes defrosting processing. The decrease in the cooling capacity due to can be compensated by cooling with the air conditioner.
FIG. 13 is a flowchart showing an operation related to the dew prevention process of the showcase 110.

The control unit 906 of the showcase 110 measures the temperature and humidity of the air in the trap unit 120 based on the temperature information and the humidity information sequentially transmitted from the temperature sensor 130 and the humidity sensor 140 (step S1301).
The control unit 906 compares the measured temperature and humidity with the threshold value T4 and the threshold value H4, respectively. As a result of the comparison, when the temperature is equal to or higher than the threshold value T4 and the humidity is equal to or higher than the threshold value H4 (YES in step S1302), the inside of the store 1 may be hotter and the humidity may be increased. Since dew condensation is likely to occur in the showcase 110, the control unit 906 turns on the dew-proof heater 112 of the showcase 110 (step S1303).

Then, the control unit 906 notifies the air conditioner 100 that the dew proof heater 112 has been turned on (step S1304).
When the temperature is equal to or higher than the threshold value T4 and the humidity is not higher than the threshold value H4 (NO in step S1302), the control unit 906 turns off the dew-proof heater 112 (step S1305).

The control unit 906 repeatedly executes the process shown in FIG. Thereby, the showcase 110 executes control according to the state of the trap unit 120, can execute control that predicts how the situation in the store 1 will change thereafter, and executes dew prevention processing The decrease in cooling capacity can be compensated by cooling with an air conditioner.
FIG. 14 is a flowchart showing operations related to the illumination control process of the showcase 110.

The control unit 906 of the showcase 110 measures the temperature and humidity of the air in the trap unit 120 based on the temperature information and the humidity information sequentially transmitted from the temperature sensor 130 and the humidity sensor 140 (step S1401).
The control unit 906 compares the measured temperature and humidity with the threshold value T5 and the threshold value H5, respectively. As a result of the comparison, if the temperature is equal to or higher than the threshold value T5 and the humidity is equal to or higher than the threshold value H5 (YES in step S1402), the inside of the store 1 may be hotter and the humidity may be increased. Since much power is consumed by the cooling process, the control unit 906 turns off part or all of the lighting device 116 serving as a heat load so as not to prevent the cooling of the showcase 110 (step S1403). .

When the temperature is equal to or higher than the threshold value T5 and the humidity is not equal to or higher than the threshold value H5 (NO in step S1402), the control unit 906 turns on the lighting device 116 if it is not turned on and turns it on. If there is nothing that has not been performed, or if a certain number of lights are turned on, the processing is terminated without doing anything.
The control unit 906 repeatedly executes the process shown in FIG. Thereby, the showcase 110 can execute control according to the state of the trap unit 120 and predict how the situation in the store 1 will change thereafter. When the lighting device 116 is turned on, power is consumed and heat due to lighting is generated. Therefore, when raising the cooling capacity, it is possible to suppress power supplied to the lighting device 116 and to suppress heat generation by turning off the lights.

The cooling efficiency can be increased by cooling the product.

Moreover, the vicinity of the showcase can be preferentially cooled over the other by providing the position of the air outlet for blowing cool air from the air conditioner in the vicinity of the showcase. Therefore, the load for cooling the products on which the showcase is displayed is reduced, and the power consumption of the showcase can be reduced. Accordingly, the showcase can effectively cool the displayed items.
Moreover, by providing a temperature sensor and a humidity sensor in the trap part, the air conditioner and the showcase can know the state of the outside air that flows in quickly, and the cooling capacity can be increased accordingly.

<Modification>
Although the air conditioning system according to the present invention has been described according to the above embodiment, the present invention is not limited to this. Hereinafter, various modifications included as the idea of the present invention will be described.

(1) In the said embodiment, the trap part 120 is formed by providing the ceiling one step higher in a ceiling part. However, this may be any other structure as long as it has a structure in which air having a higher temperature than others tends to gather (is likely to stay). In the following, some configuration examples that can be taken as the trap unit will be described.
The trap part 120 should just be the structure where air with a temperature higher than the inside of the store 1 which flows in from the door 10 stays fundamentally. Therefore, a structure other than a structure in which the ceiling is raised one step may be used. As shown in FIG. 15, a partition 1500 is placed in the middle of the ceiling so as to block high-temperature air from the door 10 through the ceiling to the back of the store 1. And the door 10 side of the area delimited by the partition 1500 may be used as the trap portion 120.

  In this case, in the vicinity of the partition 1500, high-temperature air starts to loop, and the air conditioner 100 sucks and cools the high-temperature air from the intake port 101, so that it exceeds the partition 1500. It is possible to reduce the inflow amount of high-temperature air flowing into the back of the store. As shown in FIG. 15, when the partition 1500 is used to form the trap part 120, the air conditioner 100 can be installed on the back of the ceiling. However, also in this case, the intake port 101 is configured on the trap portion 120 side, and the blower port 105 is configured on the side opposite to the trap portion 120. As a result, as in the case where the air outlet 105 is provided on the trap part 120 side, the high-temperature air in the store 1 collected in the trap part 120 is disturbed, and as a result, the high-temperature air and cold air are mixed. Thus, the gas sucked from the air inlet 101 becomes air whose temperature has been neutralized by the cold air, and it is possible to prevent the cooling efficiency in the store 1 from being lowered.

The partition 1500 shown in FIG. 15 may be configured to be removable, or may be stretched by a mechanical mechanism so as to be stretchable, or stored to allow air to pass through. May be.
Alternatively, in the above embodiment, the trap portion 120 has a structure in which the entire surface is raised to the left and right as viewed from the entrance / exit side, but this need not be the entire surface, and the ceiling is simply raised by one step. As long as it has a structure, as shown in FIG. 16A, a structure part in which a part of the ceiling is raised one step may be used as the trap part 120. Further, the shape of the dent need not be a cubic shape, and may be a triangular prism or a cylindrical shape.

  Further, as shown in FIGS. 16B and 17, the trap portion 120 shown in FIG. 1 may be formed in a U shape so that only the intake port portion is further recessed. Further, the front portion of the intake port 101 may be configured to be higher in the trap portion 120 so that air having higher temperature collects in front of the intake port 101. FIG. 17 is a plan view of the store 1 showing the configuration of the trap portion shown in FIG.

In addition, Fig.16 (a) and FIG.16 (b) have shown the figure at the time of seeing the store 1 from the entrance / exit side lower side.
Such a trap portion 120 may be configured from the stage of building the store 1 or may be formed in such a manner that a part of the ceiling of the existing store 1 is removed and a side wall is provided at the removed location.

  (2) As shown in the first embodiment, in the case of the open-type showcase 110, the cooling of the inside of the showcase 110 is performed by blowing off cold air from the discharge port 114. The place depends on it. Therefore, when the air curtain is disturbed by the cold air sent from the air blowing port 105, the cooling effect may be lowered, which is not preferable.

Therefore, the air conditioning system may be provided with a shielding portion that shields the cool air to some extent so that the cool air from the air blowing port 105 does not directly hit the showcase 110.
That is, for example, as shown in FIG. 18, a partition 1801 may be provided as a shielding portion between the air outlet 105 and the showcase 110 in the ceiling portion.
Or as shown in FIG. 19, it is good also as providing the collar 1901 in the showcase 110, and making this into a shielding part.

In this way, by providing the shielding portion that prevents the cool air from directly hitting, the possibility of impairing the air curtain effect of the showcase 110 can be reduced.
In addition, when a shielding part cannot be provided, the arrangement | positioning location of the ventilation port 105 so that the cold wind sent out from the ventilation port 105 blows out in the same direction as the cold wind blown out from the discharge port 114 of the showcase 110 as much as possible. It is preferable to adjust the blowing direction of the cold air from the air outlet 105.

(3) In the above embodiment, in the store 1 provided with the air conditioning system, the trap portion 120 is configured by simply providing a portion where the ceiling is one step higher than the other ceilings. You may provide the structure which air with high temperature gathers in the vicinity in the shop 1.
For example, as shown in FIG. 20, in the air conditioning system shown in FIG. 3, the ceiling of the trap unit 120 is inclined so that hot air in the store 1 can be more easily collected near the inlet 101. It may be configured. Note that the inclined ceiling may be curved.

(4) In the above embodiment, the air conditioner 100 and the showcase 110 change the set values such as the cooling process and the dew prevention process when both the temperature and the humidity of the trap unit 120 satisfy the threshold conditions. To do.
However, this control is only an example, and as long as the inside of the store 1 is kept comfortable and the control is in the direction of maintaining the quality of the goods in the showcase warehouse, both thresholds do not have to satisfy the condition, Depending on the environment of the store 1, the control may be executed only when one of the conditions of temperature and humidity is satisfied.

  Alternatively, the operator of the air conditioning system of the store 1 inputs temperature and humidity so that the customer feels comfortable in the store and the quality of the products in the showcase 110 is kept constant. A function for outputting the set value of the cooler temperature and the set value of the rotational speed of the blower fan is set in the control unit of the air conditioner 100 or the showcase 110, and the air conditioner 100 based on the output value of the function. Alternatively, the control of the showcase 110 may be executed.

The conditions may be set by the air conditioning system operator in the air conditioner 100 or the showcase 110 as appropriate.
Further, in the above embodiment, the air conditioner 100 and the showcase 110 control the operation such as the cooling process according to the temperature and humidity of the trap unit 120, but other than the information obtained from the trap unit 120, It goes without saying that the operation such as the cooling process may be controlled using information such as the internal temperature of the showcase 110, the internal humidity, and the set temperature.

  (5) In the above embodiment, the air conditioner 100 is configured to be directly connected to the air inlet 101 and the air outlet 105, but this is not limited thereto. It is sufficient that the air sucked from the intake port passes through the air conditioner 100 and is sent out from the blower port 105. For example, the intake port 101 and the air conditioner 100 are connected by a duct, or The air conditioner 100 and the air outlet 105 may be connected by a duct. In this case, the freedom degree of the installation location of the air conditioner 100 can be raised.

  (6) In the above embodiment, an example in which the air conditioner 100 and the showcase 110 perform a cooling process or the like based on information from the temperature sensor 130 and the humidity sensor 140 provided in the trap unit 120 has been described. However, this is not limited to this, and information other than the temperature sensor 130 and the humidity sensor 140 may be used as long as the information has an element that allows the temperature and humidity changes in the store 1 to be estimated in advance.

For example, an opening / closing sensor for detecting opening / closing of the entrance / exit is provided on the door, and when the opening / closing sensor is detected, the air conditioner 100 and the showcase 110 are notified of the fact. Then, when the opening / closing sensor detects that the opening / closing port is opened, the air conditioner 100 may perform control to increase the amount of air taken from the air inlet 101 or the showcase 110 to increase the cooling capacity.
Alternatively, the control may be performed according to the number of times the opening / closing sensor notifies “open” within a predetermined time, not every time the doorway opens. For example, when the number of times of opening and closing is equal to or greater than a certain number, a large amount of warm outside air flows in. Therefore, the air conditioner 100 and the showcase 110 may be controlled to be cooled more strongly. Conversely, when the number of times of opening and closing is less than a certain number, warm outside air will not flow so much, so even if control is performed to maintain or weaken the degree of cooling according to the previous store temperature Good.

  (7) In the above-described embodiment, the trap unit 120 is required mainly in the hot season outside the store 1. Therefore, a ceiling may be provided so as to hide the trap portion 120 in a season other than that. For example, you may provide the lid | cover and sliding door which hide the trap part 120, and make it the same height as another ceiling part. In such a case, when the air conditioner 100 is used as a heater, an air hole may be provided in the ceiling to warm the air in the store 1.

(8) In the above embodiment, for the cooling process of the air conditioner 100, the comparison of the temperature and humidity thresholds and the notification of the operation of the defrosting heater or dew-proof heater from the showcase 110 are linked. Of course, these may be processed independently.
(9) In the above embodiment, as a trigger for the air conditioner 100 and the showcase 110 to perform control of cooling processing, control of dew prevention processing, and the like, the comparison result of the temperature and humidity with a predetermined threshold is used. It was a trigger. However, this is not the case.

For example, the control may be performed in accordance with the temperature increase (decrease) rate per unit time or the humidity increase (decrease) rate per unit time of the air staying in the trap unit 120.
Or, it is simplified a little more, the latest temperature and humidity are compared with the temperature and humidity measured immediately before, and the control according to whether or not the difference (increase) exceeds a predetermined threshold. It is good also as performing.

(10) In the above embodiment, the lighting control process of the showcase 110 has been described as ON / OFF. However, the lighting may be turned off. In other words, as long as the power to be supplied to the lighting device 116 can be suppressed, a process of reducing the illumination illuminance (decreasing the brightness of the illumination) may be performed.
(11) In the above embodiment, an example is shown in which the air conditioning system is configured in one store having one room, but this is not limited thereto. It is good also as comprising in each room of the building comprised from several rooms, and good also as comprising only in some rooms.

  (12) In the above embodiment, it is described that the air conditioner 100 increases the cooling capacity in response to the notification of the defrost heater 113 or the dew proof heater 112ON from the showcase 110, but in the air conditioner system, In addition, the showcase 110 may be configured to notify the defrost heater 113 or the dew-proof heater 112 OFF, and the air conditioner 100 may be configured to restore (weaken) the cooling capacity in response to the notification. Needless to say.

  (13) In the above embodiment, the air conditioner 100 has the configuration in which the blower fan 104 is provided in the vicinity of the blower port 105. As described above, the blower fan 104 is for creating an air flow in the air conditioner 100, and the arrangement location is not necessarily near the blower opening 105. For example, instead of the blower fan 104, an air intake fan may be provided in the vicinity of the air intake port 101 and rotated to form a flow of sucking air from the air intake port 101 and sending cold air from the air blow port 105. Moreover, you may make it the structure which provides both a ventilation fan and an intake fan, and is good also as providing a fan in the position of the back | latter stage of a filter and the front | former stage of a cooler.

  (14) In the above-described embodiment, the air conditioner 100 and the showcase 110 are configured such that each control unit controls each device, but the operation of each device shown in the above-described embodiment (FIGS. 10 to 10). 14), a management server capable of communicating with the air conditioner 100 and the showcase 110 is provided in the air conditioning system, and the management server is configured to control the air conditioner 100 and the showcase 110. Good.

  (15) In the above embodiment, the cooling system includes the air conditioner 100, but the air conditioner 100 is not necessarily required. The cooling system detects the temperature of the trap part 120 that can efficiently collect (stagnate) warm outside air (relatively high temperature air in the building) flowing into the building, and the air temperature of the trap part 120, and sequentially The temperature sensor 130 that transmits the detected temperature to the showcase 110 and / or the humidity sensor 140 that detects the humidity of the air in the trap unit 120 and sequentially transmits the detected humidity to the showcase 110, and the showcase 110 If there is.

  (16) The operation related to the air-conditioning process shown in the above-described embodiment, the cooling process of the showcase, etc. (see FIGS. 10 to 14) are applied to processors such as an air conditioner and a showcase, and various circuits connected to the processor. A control program comprising program codes for execution can be recorded on a recording medium, or can be distributed and distributed via various communication paths. Such recording media include IC cards, hard disks, optical disks, flexible disks, ROMs, and the like. The distributed and distributed control program is used by being stored in a memory or the like that can be read by the processor, and the processor executes the control program, thereby realizing various functions as shown in the embodiment. Will come to be.

  (17) Each functional unit of the air conditioner 100 or the showcase 110 shown in the above embodiment may be realized as a circuit that executes the function, or by executing a program by one or a plurality of processors. It may be realized. In addition, the storage battery pack of the above embodiment may be configured as an IC (Integrated Circuit), LSI (Large Scale Integration) or other integrated circuit package. This package is incorporated into various devices for use, whereby the various devices realize the functions as shown in the embodiments.

  Each functional block is typically realized as an LSI which is an integrated circuit. These may be individually made into one chip, or may be made into one chip so as to include a part or all of them. The name used here is LSI, but it may also be called IC, system LSI, super LSI, or ultra LSI depending on the degree of integration. Further, the method of circuit integration is not limited to LSI's, and implementation using dedicated circuitry or general purpose processors is also possible. An FPGA (Field Programmable Gate Array) that can be programmed after manufacturing the LSI, or a reconfigurable processor that can reconfigure the connection and setting of circuit cells inside the LSI may be used.
