Detailed Description
In the ceiling-suspended air conditioner described in the above patent document, although not shown, a downward air outlet is generally provided on the lower surface of the ceiling-suspended air conditioner. Further, in the conventional interior, a double-deck ceiling structure is used in which spaces such as piping and wiring of a ceiling are partitioned by using panels or the like for the ceiling of a building itself, and in recent years, there are increasing cases where no partitioned double-deck ceiling is provided as described in the above-mentioned patent document. In the case of the double-deck ceiling, the air outlet of the ceiling-suspended air conditioner is exposed to the living space, and the space above the air outlet is located in the double-deck ceiling and is not included in the living space. However, when the ceiling is not a double-deck ceiling, the interior is constructed by a frame ceiling in which the space up to the ceiling of the building is directly included in the living space, and thus, an environment in which the space above the air outlet of the ceiling-suspended air conditioner is included in the living space arises. In such a case, air is likely to be accumulated in a space above the air outlet of the ceiling-suspended air conditioner. As a result, the heat discharged from the ceiling-suspended air conditioner is also likely to accumulate in the space.
As a result of extensive analysis, the present inventors have conceived the following.
That is, a 1 st aspect of the present disclosure provides a fan apparatus including: a fan; and an installation unit for installing the fan on the ceiling-suspended air conditioner above the air outlet of the ceiling-suspended air conditioner.
By providing the fan device in the ceiling-suspended air conditioner, air stagnation in a space above the air outlet of the ceiling-suspended air conditioner is reduced, and accumulation of warm air in the space is reduced.
A 2 nd aspect of the present disclosure provides a fan apparatus comprising: in the above aspect 1, the present invention includes: a receiver which receives a signal from an external device; and a controller that controls an operation of the fan based on the signal.
With this configuration, the fan device can be appropriately controlled in consideration of a signal from an external device.
A 3 rd aspect of the present disclosure provides the following fan apparatus: in the above-described mode 2, the receiver is a receiver that receives a start/stop signal of the operation of the fan.
With this configuration, the fan device can be appropriately controlled based on the start/stop signal from the outside.
The 4 th aspect of the present disclosure provides the following fan apparatus: in the above-described 2 nd aspect, the receiver is a receiver that receives a signal relating to a start/stop state of the ceiling-suspended air conditioner.
With this configuration, the fan device can be appropriately controlled according to the start/stop state of the ceiling-suspended air conditioner.
A 5 th aspect of the present disclosure provides a fan apparatus comprising: in the above-described 4 th aspect, the controller may operate the fan when the receiver receives a signal that the ceiling-suspended air conditioner is in an activated state, and may stop the operation of the fan when the receiver receives a signal that the ceiling-suspended air conditioner is in a deactivated state.
When the ceiling-suspended air conditioner is started, there is a case where heat unevenness such as accumulation of heat is generated because no flow is formed in a space above an air outlet of the ceiling-suspended air conditioner.
Here, according to the 5 th aspect, the space is also included, and convection of air occurs, thereby alleviating the uneven heat accumulation in the space.
The 6 th aspect of the present disclosure provides the following fan apparatus: in the above-described 4 th aspect, the controller may operate the fan when the receiver receives a signal that the ceiling-suspended air conditioner is in a stopped state, and the controller may stop the operation of the fan when the receiver receives a signal that the ceiling-suspended air conditioner is in an activated state.
When the ceiling-suspended air conditioner is stopped, there may be a case where heat unevenness such as accumulation of heat is generated because no flow is formed in a space above the air outlet of the ceiling-suspended air conditioner. In particular, when a ceiling-mounted air conditioner different from a stopped ceiling-mounted air conditioner is in an activated state, the ceiling-mounted air conditioner is affected by an airflow generated by the ceiling-mounted air conditioner in the activated state, while the ceiling-mounted air conditioner in the stopped state does not generate an airflow. Therefore, the space above the air outlet of the ceiling-suspended air conditioner in the stopped state may be warmed.
Here, according to the 6 th aspect, the space is also included, convection of air is generated, and uneven heat accumulation in the space due to heat is alleviated.
The 7 th aspect of the present disclosure provides the following fan apparatus: in the above-described 2 nd aspect, the receiver is a receiver that receives a signal relating to an operation mode being executed in the ceiling-suspended air conditioner.
With this configuration, the fan device can be appropriately controlled according to the operation mode of the ceiling-suspended air conditioner.
An 8 th aspect of the present disclosure provides a fan apparatus comprising: in the above-described 7 th aspect, the operation modes include a heating mode in which the ceiling-mounted air conditioner performs a heating operation and a cooling mode in which the ceiling-mounted air conditioner performs a cooling operation, and the controller controls the operation of the fan in accordance with a start/stop state of the ceiling-mounted air conditioner when the receiver receives a signal indicating that the ceiling-mounted air conditioner is in the heating mode, and stops the fan when the receiver receives a signal indicating that the ceiling-mounted air conditioner is in the cooling mode.
When the ceiling-mounted air conditioner is in the heating mode, warm heat is discharged from the ceiling-mounted air conditioner, and a state in which warm heat is accumulated above is likely to occur. Here, according to the 8 th aspect, when the ceiling-suspended air conditioner is set to the heating mode, the fan device is activated/deactivated in conjunction with the activated/deactivated state of the ceiling-suspended air conditioner. On the other hand, in the cooling mode, the state where the cold air flows downward (manned area) within the range of the set temperature is not an environmental state which is particularly problematic. Therefore, when the ceiling-mounted air conditioner is set to the cooling mode, the fan device is not operated regardless of the on/off state of the air conditioner. With such operation control, when uneven heating in a space above the air outlet of the ceiling-suspended air conditioner becomes a problem, a fan operation for alleviating the uneven heating is performed.
A 9 th aspect of the present disclosure provides the following fan apparatus: in the above-described 7 th aspect, the operation modes include a 1 st air volume mode in which the air volume of the ceiling-mounted air conditioner is small and a 2 nd air volume mode in which the air volume of the ceiling-mounted air conditioner is large, and the controller operates the fan when the receiver receives a signal indicating that the ceiling-mounted air conditioner is in the 1 st air volume mode, and stops the operation of the fan when the receiver receives a signal indicating that the ceiling-mounted air conditioner is in the 2 nd air volume mode.
In the 1 st air volume mode with a small air volume, the air flow formed by the ceiling-suspended air conditioner is small, and therefore uneven heating tends to occur in the space above the air outlet of the ceiling-suspended air conditioner. Here, according to the 9 th aspect, the fan device is activated. This also includes the space, and generates convection of air, thereby reducing uneven heat accumulation in the space. On the other hand, in the 2 nd operation mode in which the air volume is large, the air flow formed by the ceiling-suspended air conditioner is large, and therefore, the unevenness of the heat generated in the space is relatively light. Here, according to the 9 th aspect, the fan apparatus is stopped. This can suppress excessive occurrence of air convection in the building including the space. Such operation control effectively reduces uneven heating in the space.
A 10 th aspect of the present disclosure provides a fan apparatus comprising: in the 7 th aspect, the operation modes include a 1 st wind direction mode in which a downward inclination of the wind direction of the ceiling-mounted air conditioner is small and a 2 nd wind direction mode in which the downward inclination of the wind direction of the ceiling-mounted air conditioner is large, and the controller operates the fan when the receiver receives a signal indicating that the ceiling-mounted air conditioner is in the 1 st wind direction mode, and stops the operation of the fan when the receiver receives a signal indicating that the ceiling-mounted air conditioner is in the 2 nd wind direction mode.
When the operation mode of the ceiling-suspended air conditioner is the 1 st wind direction mode in which the wind direction of the ceiling-suspended air conditioner is inclined downward, since the air flow generated by the ceiling-suspended air conditioner is generated above the room (relatively above the manned area), the air convection in the entire room is not easily generated, and uneven heating is easily generated in the space above the air outlet of the ceiling-suspended air conditioner. Here, according to the 10 th aspect, the fan device is activated. This also includes the space, and generates convection of air, thereby reducing uneven heat accumulation in the space. On the other hand, in the 2 nd wind direction mode in which the wind direction of the ceiling-mounted air conditioner is inclined downward and largely, the air flow generated by the ceiling-mounted air conditioner reaches the lower side of the room, so that convection of air in the whole room is easily generated, and unevenness in temperature generated in the space is relatively light. Here, according to the 10 th aspect, the fan apparatus is stopped. It is possible to suppress excessive occurrence of air convection in the building including the space. Such operation control effectively reduces uneven heating in the space.
An 11 th aspect of the present disclosure provides a fan apparatus comprising: in the above-described 2 nd aspect, the receiver is a receiver that receives a signal relating to a temperature of air taken in by the ceiling-suspended air conditioning apparatus.
With this configuration, the fan device can be appropriately controlled according to the temperature of air taken in by the ceiling-suspended air conditioner.
A 12 th aspect of the present disclosure provides the following fan apparatus: in the above-described aspect 2, the receiver is a receiver that receives a signal relating to an environment in which the fan is used.
With this configuration, the fan device can be appropriately controlled according to the use environment of the fan.
A 13 th aspect of the present disclosure provides the following fan apparatus: in the above-described 12 th aspect, the usage environment is humidity, and the controller operates the fan when the receiver receives a signal indicating that the humidity is high, and stops the operation of the fan when the receiver receives a signal indicating that the humidity is low.
As a use environment of the fan device, when the humidity is high, moisture in the air tends to accumulate above, particularly, in a space above the air outlet of the ceiling-suspended air conditioner. Here, according to the 13 th aspect, the fan device is activated. This generates an air flow in the space, thereby reducing the occurrence of condensation and mold formation near the ceiling. On the other hand, according to the 13 th aspect, when the humidity is low, the fan apparatus is stopped as the use environment of the fan apparatus. This suppresses excessive operation of the fan device. Such operation control effectively reduces the accumulation of moisture in the space.
A 14 th aspect of the present disclosure provides the following fan apparatus: in the above-described 12 th aspect, the use environment is the start/stop state of another ceiling-mounted air conditioner different from the ceiling-mounted air conditioner provided with the fan device.
With this configuration, the fan device can be appropriately controlled according to the start/stop state of another ceiling-mounted air conditioner different from the ceiling-mounted air conditioner provided with the fan device.
A 15 th aspect of the present disclosure provides a fan apparatus including: a detector that detects a usage environment of the fan device; and a controller that controls an operation of the fan based on the usage environment of the fan detected by the detector.
With this configuration, the fan device can be appropriately controlled according to the use environment of the fan.
A 16 th aspect of the present disclosure provides the following fan apparatus: in the above 8 th aspect, the detector is provided above an air outlet of the ceiling-suspended air conditioning equipment.
With this configuration, the fan device can be appropriately controlled according to the use environment of the fan.
A 17 th aspect of the present disclosure provides a ceiling-suspended air conditioning apparatus comprising: a fan of the fan device according to any one of the above 1 to 16 is mounted via the mounting device above an air outlet of the ceiling-suspended air conditioning apparatus.
With this configuration, the fan device is installed in the ceiling-suspended air conditioner, and therefore, by appropriately operating the fan device, the stagnation of air in the space above the air outlet of the ceiling-suspended air conditioner is reduced, and the accumulation of warm heat (warm air) in the space is reduced.
Hereinafter, embodiments will be described in detail with reference to the drawings. The embodiments described below are all general or specific examples. The numerical values, shapes, components, arrangement positions and connection modes of the components, steps of processing, order of the steps, and the like shown in the following embodiments are examples. Accordingly, the present disclosure is not limited to this manner. Among the components in the following embodiments, those not recited in the independent claims indicating the most generic concept of the present disclosure will be described as arbitrary components.
The drawings are schematic and are not strictly shown. In the drawings, substantially the same components are denoted by the same reference numerals, and redundant description may be omitted or simplified.
(embodiment 1)
[ Structure of the device ]
Fig. 1 is a schematic view showing an example of a fan apparatus according to embodiment 1.
As shown in fig. 1, the fan apparatus 100 of the present embodiment has a fan 1, a receiver 2, a controller 3, a fan apparatus main body 5, and a mounting device 6.
The fan 1 blows air.
The receiver 2 receives signals from an external device. The external device may be a control device that controls the entirety of a plurality of ceiling-mounted air conditioners, for example.
The controller 3 controls the operation of the fan 1. The controller 3 may have a control function, and includes an arithmetic processing unit (not shown) and a storage unit (not shown) for storing a control program. The MPU and the CPU are exemplified as the arithmetic processing unit. The storage unit is exemplified by a memory. The controller may be a single controller that performs centralized control, or may be a plurality of controllers that perform distributed control in cooperation with each other.
The fan apparatus main body 5 has the fan 1, the receiver 2, the controller 3, and a casing 5A in which these are built.
The mounting unit 6 is a unit for mounting the fan to the ceiling-mounted air conditioner at a position above the air outlet of the ceiling-mounted air conditioner. Specifically, a mounting metal member or the like is exemplified.
As shown in fig. 2, the ceiling-suspended air conditioner 200 has an air outlet 7 and a fan unit 100.
The air supply outlet 7 is provided on the lower surface of the ceiling-suspended air conditioner 200. Air is blown downward from the air blowing port 7.
The fan apparatus 100 is attached to the ceiling-mounted air conditioner 200 via the attachment unit 6, and thereby the fan 1 of the fan apparatus 100 is attached to a position above the air outlet 7 of the ceiling-mounted air conditioner 200.
In the example shown in fig. 2, the air blown from the fan apparatus 100 flows upward. This air flow generates convection of air including a space above the air outlet 7, and thus, uneven heating in the space is alleviated. Further, with respect to the position of the mounter 6, depending on the structure of the fan apparatus 100, it may be used under the fan apparatus 100 in addition to the side of the fan apparatus 100.
An example of the ceiling-mounted air conditioner 200 of fig. 3 will be described. As shown in fig. 3, in the ceiling-mounted air conditioner 200, unlike the example shown in fig. 2, the fan apparatus 100 is mounted to the ceiling-mounted air conditioner 200 using a plurality of mounting devices 6. The air blown from the fan apparatus 100 flows upward. This causes convection of air including a space above the air blowing port 7, thereby reducing uneven heating in the space. Further, with respect to the positions of the plurality of mounters 6, a plurality may be used at the side of the fan apparatus 100 and/or a plurality may be used below the fan apparatus 100, depending on the weight or structure of the fan apparatus 100.
An example of the ceiling-mounted air conditioner 200 of fig. 4 will be described. As shown in fig. 4, a ceiling-mounted air conditioning system 200 is provided with a plurality of fan devices 100, unlike the example shown in fig. 2. In this example, the ceiling-suspended air conditioner 200 is provided on both sides thereof. The air blown from the fan apparatus 100 flows upward. This causes convection of air including a space above the air blowing port 7, thereby reducing uneven heating in the space.
An example of the ceiling-mounted air conditioner 200 of fig. 5 will be described. As shown in fig. 5, a ceiling-mounted air conditioning system 200 is provided with a plurality of fan devices 100, unlike the example shown in fig. 2. In this example, the ceiling-suspended air conditioner 200 is provided on both sides thereof. The air blown from the fan device 100 flows diagonally upward and outward. This causes convection of air including a space above the air blowing port 7, thereby reducing uneven heating in the space. Further, the air blown from the fan device 100 may be directed horizontally outward.
An example of the ceiling-mounted air conditioner 200 of fig. 6 will be described. As shown in fig. 6, a ceiling-mounted air conditioning system 200 is provided with a plurality of fan devices 100, unlike the example shown in fig. 2. In this example, the ceiling-suspended air conditioner 200 is provided on both sides thereof. The air blown from the fan device 100 flows inward in the horizontal direction. This causes convection of air including a space above the air blowing port 7, thereby reducing uneven heating in the space. Further, the air blown from the fan device 100 may be directed obliquely upward and inward.
[ work ]
Next, the operation of the fan apparatus 100 will be explained.
Fig. 7 is a flowchart illustrating an example of the operation of the fan apparatus 100 according to embodiment 1.
As shown in fig. 7, first, a signal indicating which of the on state and the off state the ceiling-suspended air conditioner is in is received from the external apparatus via the receiver 2 (step S11). Next, the controller 3 determines whether or not the ceiling-suspended air conditioner is in an activated state based on the signal received by the receiver 2 (step S12). When the ceiling-mounted air conditioner is in the on state (yes in step S12), the controller 3 operates the fan device 100 (step S13). When the ceiling-mounted air conditioner is in the stopped state (no in step S12), the controller 3 stops the operation of the fan device 100 (step S14).
When the ceiling-mounted air conditioner 200 is started, there may be a case where heat unevenness such as heat accumulation occurs because no flow is formed in a space above the air outlet 7 of the ceiling-mounted air conditioner 200.
Here, according to the above operation, the space is also included, and convection of air is generated, thereby alleviating uneven heat accumulation in the space due to heat.
(embodiment 2)
A fan apparatus 100 according to embodiment 2 will be described. The fan apparatus 100 of the present embodiment has the same configuration as the fan apparatus 100 of embodiment 1, and therefore, detailed description thereof is omitted.
[ work ]
The operation of the fan device 100 of the present embodiment will be described.
Fig. 8 is a flowchart illustrating an example of the operation of the fan apparatus 100 according to embodiment 2.
As shown in fig. 8, first, a signal indicating which of the on state and the off state the ceiling-suspended air conditioner 200 is in is received from an external apparatus via the receiver 2 (step S21). Next, the controller 3 determines whether the ceiling-suspended air conditioner 200 is in a stopped state based on the signal received by the receiver 2 (step S22). When the ceiling-mounted air conditioner 200 is in the stopped state (yes in step S22), the controller 3 operates the fan device 100 (step S23). When the ceiling-mounted air conditioner 200 is in the on state (no in step S22), the controller 3 stops the operation of the fan device 100 (step S24).
When the ceiling-mounted air conditioning system 200 is stopped, there may be a case where heat unevenness such as accumulation of heat is generated because no flow is formed in a space above the air outlet 7 of the ceiling-mounted air conditioning system 200. In particular, when the ceiling-mounted air conditioner 200 different from the stopped ceiling-mounted air conditioner 200 is in the activated state, the ceiling-mounted air conditioner 200 in the activated state is influenced by the airflow generated by the ceiling-mounted air conditioner 200 in the activated state, while the ceiling-mounted air conditioner 200 in the stopped state does not generate the airflow. Then, the heat may accumulate in the space above the air outlet 7 of the ceiling-suspended air conditioner 6 device 200 in the stopped state.
Here, according to the above operation, the space is also included, and convection of air is generated, thereby alleviating uneven heat accumulation in the space due to heat.
(embodiment 3)
A fan apparatus 100 according to embodiment 3 will be described. The fan apparatus 100 of the present embodiment has the same configuration as the fan apparatus 100 of embodiment 1, and therefore, detailed description thereof is omitted.

Fig. 9 is a flowchart illustrating an example of the operation of the fan apparatus 100 according to embodiment 3.
As shown in fig. 9, first, a signal relating to the operation mode of the ceiling-suspended air conditioner 200 is received from an external device via the receiver 2 (step S31). In this example, the operation modes include a heating mode in which the ceiling-mounted air conditioner 200 performs a heating operation and a cooling mode in which the ceiling-mounted air conditioner 200 performs a cooling operation. Next, the controller 3 determines whether the ceiling-suspended air conditioner 200 is in the heating mode based on the signal received by the receiver 2 (step S32). When the operation mode of the ceiling-mounted air conditioner 200 is the heating mode (yes in step S32), the controller 3 operates the fan device 100 in accordance with the on/off state of the ceiling-mounted air conditioner (step S33). Specifically, the control of the fan apparatus 100 shown in fig. 7 or 8 is executed. When the operation mode of the ceiling-mounted air conditioner 200 is not the heating mode (no in step S32), it is determined whether the operation mode of the ceiling-mounted air conditioner 200 is the cooling mode (step S34). When the operation mode of the ceiling-mounted air conditioner 200 is the cooling mode (yes in step S34), the controller 3 stops the operation of the fan device 100 (step S35). When the operation mode of the ceiling-mounted air conditioner 200 is not the cooling mode (no in step S34), the control flow of the fan apparatus 100 of the present embodiment is terminated.
When the ceiling-mounted air conditioner 200 is in the heating mode, the heat is discharged from the ceiling-mounted air conditioner 200, and the heat tends to accumulate in the upper portion. Here, according to the above operation, when the ceiling-suspended air conditioner 200 is set to the heating mode, the fan device is activated/deactivated in conjunction with the activated/deactivated state of the ceiling-suspended air conditioner 200. This alleviates uneven heating in the space above the air outlet 7 of the ceiling-suspended air conditioner.
On the other hand, in the cooling mode, the state where the cold air flows downward (manned area) within the range of the set temperature is not an environmental state which is particularly problematic. Therefore, when the ceiling-mounted air conditioner is set to the cooling mode, the fan device is not operated regardless of the on/off state of the air conditioner. By such operation control, excessive operation of the fan device 100 is suppressed, and energy consumption is reduced.
That is, the above operation of the fan device 100 effectively alleviates uneven heating in the space above the air outlet 7 of the ceiling-suspended air conditioner.

A fan apparatus 100 according to embodiment 4 will be described. The fan apparatus 100 of the present embodiment has the same configuration as the fan apparatus 100 of embodiment 1, and therefore, detailed description thereof is omitted.

The operation of the fan device 100 of the present embodiment will be described.
Fig. 10 is a flowchart illustrating an example of the operation of the fan apparatus 100 according to embodiment 4.
As shown in fig. 10, first, a signal relating to the operation mode of the ceiling-suspended air conditioner 200 is received from an external device via the receiver 2 (step S41). In this example, the operation modes include the 1 st air volume mode in which the air volume of the ceiling-mounted air conditioner 200 is small and the 2 nd air volume mode in which the air volume of the ceiling-mounted air conditioner 200 is large. Next, the controller 3 determines whether or not the operation mode of the ceiling-suspended air conditioner 200 is the 1 st air volume mode based on the signal received by the receiver 2 (step S42). When the operation mode of the ceiling-mounted air conditioner 200 is the 1 st air volume mode (yes in step S42), the controller 3 operates the fan device 100 (step S43). When the operation mode of the ceiling-mounted air conditioner 200 is not the 1 st air volume mode (no in step S42), the controller 3 determines whether or not the operation mode of the ceiling-mounted air conditioner 200 is the 2 nd air volume mode (step S44). When the operation mode of the ceiling-mounted air conditioner 200 is the 2 nd air volume mode, the operation of the fan device 100 is stopped (step S45). When the operation mode of the ceiling-suspended air conditioner 200 is not the 2 nd air volume mode (no in step S44), the control flow of the present embodiment is terminated.
In the 1 st air volume mode with a small air volume, the ceiling-suspended air conditioner 200 forms a small air flow, and uneven heating tends to occur in the space above the air outlet 7 of the ceiling-suspended air conditioner. Here, the fan apparatus 100 is activated in accordance with the above operation. This also includes the space, and generates convection of air, thereby reducing uneven heat accumulation in the space. On the other hand, in the 2 nd operation mode in which the air volume is large, the air flow formed by the ceiling-suspended air conditioner 200 is large, and therefore, the unevenness of the heat generated in the space is relatively light. Here, the fan device is stopped in accordance with the above operation. This can suppress excessive occurrence of air convection in the building including the space. Such operation control effectively reduces uneven heating in the space.
(embodiment 5)
A fan apparatus 100 according to embodiment 5 will be described. The fan apparatus 100 of the present embodiment has the same configuration as the fan apparatus 100 of embodiment 1, and therefore, detailed description thereof is omitted.
[ work ]
The operation of the fan device 100 of the present embodiment will be described.
Fig. 11 is a flowchart illustrating an example of the operation of the fan apparatus 100 according to embodiment 5.
As shown in fig. 11, first, a signal relating to the operation mode of the ceiling-suspended air conditioner 200 is received from an external device via the receiver 2 (step S51). In this example, the operation modes include a 1 st wind direction mode in which the wind direction of the ceiling-mounted air conditioner 200 is inclined downward by a small amount and a 2 nd wind direction mode in which the wind direction of the ceiling-mounted air conditioner 200 is inclined downward by a large amount. Next, the controller 3 determines whether the ceiling-suspended air conditioner 200 is in the 1 st wind direction mode based on the signal received by the receiver 2 (step S52). When the operation mode of the ceiling-mounted air conditioner 200 is the 1 st wind direction mode (yes in step S52), the controller 3 operates the fan device 100 (step S53). When the operation mode of the ceiling-mounted air conditioner 200 is not the 1 st airflow direction mode (NO at step S52), it is determined whether the operation mode of the ceiling-mounted air conditioner 200 is the 2 nd airflow direction mode (step S54). When the operation mode of the ceiling-mounted air conditioner 200 is the 2 nd airflow direction mode (yes in step S54), the controller 3 stops the operation of the fan device 100 (step S55). When the operation mode of the ceiling-mounted air conditioner 200 is not the 2 nd airflow direction mode (no in step S54), the control flow of the fan device 100 of the present embodiment is terminated.
When the operation mode of the ceiling-mounted air conditioner 200 is the 1 st wind direction mode in which the wind direction of the ceiling-mounted air conditioner 200 is inclined downward, the air flow generated by the ceiling-mounted air conditioner 200 is generated above the room (relatively above the manned area), and therefore, convection of air in the whole room is not easily generated, and uneven heating is easily generated in the space above the air outlet 7 of the ceiling-mounted air conditioner 200. Here, the fan apparatus 100 is activated in accordance with the above operation. This also includes the space, and generates convection of air, thereby reducing uneven heat accumulation in the space. On the other hand, in the 2 nd wind direction mode in which the wind direction of the ceiling-mounted air conditioner 200 is inclined downward and is large, the air flow formed by the ceiling-mounted air conditioner 200 reaches the lower side of the room, so that convection of air in the whole room is easily generated, and unevenness in temperature generated in the space is relatively light. Here, the fan device is stopped in accordance with the above operation. This can suppress excessive occurrence of air convection in the building including the space. Such operation control effectively reduces uneven heating in the space.
Further, the wind direction does not necessarily have to be the one in which the airflow is generated only in the desired direction of the equipment, and the airflow often changes depending on the building structure and the like, and therefore, it may be appropriate to set the control method (as a timing, a control method that is the reverse of the above operation) depending on the usage environment, the operating condition, and the thermal environment. In this case, the fan apparatus 100 may be configured to be capable of changing the control logic for starting and stopping the operation.
(embodiment 6)
A fan apparatus 100 according to embodiment 6 will be described. The fan apparatus 100 of the present embodiment has the same configuration as the fan apparatus 100 of embodiment 1, and therefore, detailed description thereof is omitted.
[ work ]
The operation of the fan device 100 of the present embodiment will be described.
Fig. 12 is a flowchart illustrating an example of the operation of the fan apparatus 100 according to embodiment 6.
As shown in fig. 12, first, a signal relating to the temperature of the ceiling-suspended air conditioner 200 is received from an external apparatus via the receiver 2 (step S61). Next, the controller 3 determines whether or not the temperature of the air taken in by the ceiling-suspended air conditioner 200 is equal to or higher than a threshold value Tth based on the signal received by the receiver 2 (step S62). When the temperature of the air taken in by the ceiling-suspended air conditioner 200 is equal to or higher than the threshold value Tth, the controller 3 operates the fan device 100 (step S63). When the temperature of the air taken in by the ceiling-mounted air conditioner 200 is less than the threshold value Tth (no in step S62), the controller 3 stops the operation of the fan device 100 (step S64).
When the temperature of the air taken in by the ceiling-mounted air conditioner 200 is high, it is estimated that the temperature of the space above the air outlet 7 of the ceiling-mounted air conditioner 200 is not uniform. Here, the uneven warming of the space is alleviated by the above operation. When the temperature of the air sucked into the ceiling-mounted air conditioning apparatus 200 is low, it is estimated that the temperature unevenness in the space is small. Here, the above operation can suppress excessive occurrence of air convection in the building including the space. Such operation control effectively reduces uneven heating in the space.
In the above-described working example, the temperature of the air sucked into the ceiling-mounted air conditioner 200 may be, for example, the temperature in the vicinity of the suction port (not shown) of the ceiling-mounted air conditioner 200, but is not limited to this example. Any means may be used as long as the temperature of the air sucked into the ceiling-mounted air conditioner 200 can be detected.
(7 th embodiment)
A fan apparatus 100 according to embodiment 7 will be described. The fan apparatus 100 of the present embodiment has the same configuration as the fan apparatus 100 of embodiment 1, and therefore, detailed description thereof is omitted.
[ work ]
The operation of the fan device 100 of the present embodiment will be described.
Fig. 13 is a flowchart illustrating an example of the operation of the fan apparatus 100 according to embodiment 7.
As shown in fig. 13, first, a signal relating to the use environment of the fan apparatus 100 is received from an external device via the receiver 2 (step S71). In this example, the environment in which the fan apparatus 100 is used is humidity. Next, the controller 3 determines whether or not the humidity is equal to or higher than the threshold value Hth based on the signal relating to the humidity received by the receiver 2 (step S72). When the humidity is equal to or higher than the threshold value Hth, the controller 3 operates the fan apparatus 100 (step S73). When the humidity is less than the threshold value Hth (no in step S72), the controller 3 stops the operation of the fan apparatus 100 (step S74).
As a use environment of the fan device 100, when the humidity is high, moisture in the air tends to accumulate above, particularly, in a space above the air outlet of the ceiling-suspended air conditioner. Here, the fan apparatus 100 is activated in accordance with the above operation. This generates an air flow in the space, thereby reducing the occurrence of condensation and mold formation near the ceiling. On the other hand, as the environment in which the fan apparatus 100 is used, when the humidity is low, the fan apparatus is stopped according to the above operation. This suppresses excessive operation of the fan device 100. Such operation control effectively reduces the accumulation of moisture in the space.
The humidity is not limited to the humidity inside the building, and may be the humidity as weather data, the humidity outside the building, or the like, and may be determined based on information related to the humidity inside the building, or may be a relative humidity, an absolute humidity, or the like, and may be flexibly applied as long as it is an index indicating the humidity in the air.
(modification example)
The present disclosure is described based on the above embodiments, but the present disclosure is not limited to the above embodiments and the above modifications. The following method is also possible.
(1) As the environment in which the fan device 100 is used, the start/stop state of another ceiling-mounted air conditioner different from the ceiling-mounted air conditioner provided with the fan device may be used. Thus, the fan device can be appropriately controlled according to the start/stop state of another ceiling-mounted air conditioner different from the ceiling-mounted air conditioner provided with the fan device.
A specific example is as follows. For example, when the operation mode of the ceiling-mounted air conditioner 200 located adjacent to the ceiling-mounted air conditioner 200 provided with the fan device 100 is the heating mode, and the wind direction is the horizontal wind direction and is in the activated state, the heat tends to accumulate in the space above the air blowing port 7 of the ceiling-mounted air conditioner 200 provided with the fan device 100. Here, when it is determined that the operation mode is the heating mode and the wind direction is the horizontal wind direction and the fan apparatus 100 is in the activated state based on the signal relating to the operation of the adjacent ceiling-suspended air conditioner 200 received by the receiver 2, the fan apparatus 100 is operated. Such operation control can effectively alleviate the uneven heating in the space.
(2) Other device information and sensor information notified from the energy management system can also be used flexibly. Further, since the judgment of the operation state of the peripheral equipment is complicated over a plurality of branches, it is possible to judge the necessity of starting/stopping the operation of the corresponding fan apparatus 100 in the energy management system, receive the result, and use the result as a judgment material for controlling the starting/stopping of the operation of the fan apparatus 100.
(3) Or may not be the way in which signals relating to the environment in which the fan apparatus 100 is used are received by the receiver 2. For example, the fan apparatus 100 may have a detector for detecting its own usage environment, and the controller 3 may control the operation of the fan 1 based on the usage environment of the fan apparatus 100 detected by the detector. Examples of the detector include detectors for detecting humidity, temperature, and the like.
Industrial applicability
The present disclosure is useful as a fan device and a ceiling-suspended air conditioner that are improved in air conditioning compared to the related art.
