Moreover, the control device 60 may be configured to include the terminal and the above-mentioned installed equipment. In this case, the terminal is connected to the installed equipment by a communication means such as the Internet, and the installed equipment is connected to the floor heating system by means of communication such as Wifi (registered trademark), Bluetooth (registered trademark), and infrared communication. It is connected to the device 12 and the air conditioner 13.

Further, the control device 60 may be configured by a controller (for example, a component including the above-described control section 25) provided in the floor heating device 12. In this case, it is possible to understand the portion of the floor heating device 12 excluding the controller as an example of the floor heating device in the claims. Furthermore, the control device 60 may be configured to include an external device provided outside the living room 104 and connected to the floor heating device 12. The external device is, for example, a server device, specifically, a server device managed by a provider (for example, a manufacturer) that provides the floor heating device 12, and is connected to the floor heating device 12 by a communication means such as the Internet. be done. In this configuration, for example, it is possible to provide the input unit 64 and the communication unit 65 in the floor heating device 12, and to provide the external device with the processor 61, memory 62, and storage 63. Note that the external device may be composed of a plurality of devices.

Further, the control device 60 may be configured by a controller provided in the air conditioner 13 (for example, a component including the aforementioned control section 35). In this case, it is possible to understand the portion of the air conditioner 13 excluding the controller as an example of the air conditioner in the claims. Furthermore, the control device 60 may be configured to include an external device provided outside the living room 104 and connected to the air conditioner 13. The external device includes, for example, a server device, specifically, a server device managed by a provider (for example, a manufacturer) that provides the air conditioner 13, and is connected to the air conditioner 13 by a communication means such as the Internet. . In this configuration, for example, the air conditioner 13 can be provided with an input section 64 and a communication section 65, and the external device can be provided with a processor 61, a memory 62, and a storage 63. Note that the external device may be composed of a plurality of devices.

In the control device 60, the processor 61 implements various functions by executing the control program 63A. The functional configuration realized by the cooperation of the processor 61 as a hardware resource and the control program 63A as a software resource will be described below. FIG. 3 is a block diagram showing the functional configuration of the processor 61.

As shown in FIG. 3, in the control device 60, the processor 61 functions as an acquisition unit 61A and an operation control unit 61B by executing a control program 63A.

The acquisition unit 61A is a functional unit that acquires various instructions and information input by the user through the input unit 64. In the present embodiment, the acquisition unit 61A receives, for example, operation instructions input through the input unit 64 (for example, a combined operation instruction for operating the air conditioner 13 and the floor heating device 12 in combination), instructions regarding operating conditions, and settings. Get temperature information.

The operation control unit 61B is a functional unit that controls the operation of the floor heating device 12 and the air conditioner 13 based on the instructions acquired by the acquisition unit 61A. Specifically, the operation control unit 61B controls the operation of the floor heating device 12 and the air conditioner 13 as follows.

In this embodiment, the operation control unit 61B transmits an operation instruction to the control unit 25 of the floor heating device 12 and the control unit 35 of the air conditioner 13 via the communication unit 65, and the control unit 25 controls the floor heating. Each part of the device 12 is controlled, and the control unit 35 controls each part of the air conditioner 13, thereby controlling the operation of the floor heating device 12 and the air conditioner 13. Note that when the control device 60 is a controller provided in the floor heating device 12, the operation control section 61B transmits an operation instruction to the control section 35 of the air conditioner 13 via the communication section 65, and performs control. The unit 35 may control each part of the air conditioner 13 to control the operation of the air conditioner 13, and each part of the floor heating device 12 may be directly controlled. Further, when the control device 60 is a controller provided in the air conditioner 13, the operation control unit 61B transmits an operation instruction to the control unit 25 of the floor heating device 12 via the communication unit 65, and controls the The unit 25 may control each part of the floor heating apparatus 12 to control the operation of the floor heating apparatus 12, and each part of the air conditioner 13 may be directly controlled.

When the acquisition unit 61A acquires an operation instruction to perform independent operation of the air conditioner 13, the operation control unit 61B performs operation control on the air conditioner 13 to operate under predetermined air conditioner independent operation conditions. In this case, the operation control unit 61B does not control the operation of the floor heating device 12. Note that the air conditioner independent operating condition is a different operating condition from the later-described second combined operating condition used when the floor heating device 12 and the air conditioner 13 are operated together.

On the other hand, when the acquisition unit 61A acquires an operation instruction to perform independent operation of the floor heating device 12, the operation control unit 61B controls the operation of the floor heating device 12 to operate under predetermined floor heating independent operation conditions. Do it against. In this case, the operation control unit 61B does not control the operation of the air conditioner 13. Note that the floor heating independent operating condition is a different operating condition from the below-described first combined operating condition used when the floor heating device 12 and the air conditioner 13 are operated together.

Furthermore, when the acquisition unit 61A acquires a combined operation instruction for performing a combined operation of the floor heating device 12 and the air conditioner 13, the operation control unit 61B performs an operation that causes the floor heating device 12 and the air conditioner 13 to be operated under a predetermined first combined operation condition. The floor heating device 12 is controlled, and the air conditioner 13 is controlled to operate under the second combined operating condition in which the airflow in the living area of the living room 104 has a wind speed of less than 0.2 m/s. The living area of the living room 104 is an area where the user exists in the living room 104, and is, for example, an area from the floor surface 106 to 1800 mm above the floor. The wind speed of the airflow in the living area is, for example, the wind speed measured at a height of 1100 mm above the floor. Note that an airflow with a wind speed of less than 0.2 m/s can be said to be an insensitive airflow in which a user in a residential area hardly feels the airflow. Further, under the second combined operation condition, the airflow in the area above the living area may have a wind speed of 0.2 m/s or more.

The second combined operation condition in which the airflow in the living area of the living room 104 has a wind speed of less than 0.2 m/s is the second combined operating condition in which the wind direction of the indoor unit 30 is along the ceiling 108 of the living room 104. Is possible. Specifically, under the second combined operating condition, as an example, the louver 39 of the indoor unit 30 is located at the uppermost position from the start to the end of the operation under the second combined operating condition. At the uppermost position of the louver 39, as described above, the wind direction of the indoor unit 30 is along the ceiling 108 of the living room 104, and the wind direction of the indoor unit 30 is the direction facing the uppermost side.

Further, under the second combined operating condition, for example, the air volume of the fan 38 of the indoor unit 30 is set to be a weak air from the start to the end of the operation under the second combined operating condition. Specifically, in the second combined operation condition, the air volume of the fan 38 is set to the first stage where the air volume is the lowest, or the second stage where the air volume is the second lowest.

Note that, when the acquisition unit 61A acquires a combination operation instruction based on the second combination operation condition, the operation control unit 61B performs operation control on the air conditioner 13 to operate under the second combination operation condition, and controls the air conditioner 13 to operate under the second combination operation condition. When a combination operation instruction based on a third combination operation condition different from the combination operation condition is acquired, the air conditioner 13 may be controlled to operate under the third combination operation condition. The combination operation instruction based on the second combination operation condition includes, for example, an operation (instruction) for selecting an operation mode such as an energy saving mode, which will be described later. Further, the combination operation instruction based on the third combination operation condition includes, for example, an operation (instruction) for selecting an operation mode such as maximum air conditioning mode, which will be described later.

Furthermore, when the operation control unit 61B acquires the combined operation instruction, for example, the room temperature and the floor surface temperature reach the comfortable temperature range 63S (see FIG. 5), and after reaching the comfortable temperature range 63S, the operation control unit 61B maintains the temperature within the comfortable temperature range 63S. Operation control is performed for each of the floor heating device 12 and the air conditioner 13 to operate under each of the first combined operating condition and the second combined operating condition.

The comfortable temperature range 63S (see FIG. 5) is a preset temperature range for the room temperature and floor surface temperature. Specifically, the comfortable temperature range 63S, as shown in FIG. The felt temperature range is the temperature range set for room temperature and floor surface temperature. In this embodiment, the comfortable temperature range 63S is set within a range where the floor surface temperature is 25°C or more and 31°C or less and the room temperature is 18°C or more and 25°C or less, as shown in FIG. It is something.

In addition, in the conventional comfortable temperature range 63T, as shown in FIG. 4, the floor surface temperature was set in the range of 25°C or more and 31°C or less, and the room temperature was set in the range of 18°C or more and 23°C or less. . This was studied by the ``Research Committee on Amenity Evaluation of Floor Heating'' established by the Japan Society of Air Conditioning and Sanitary Engineers from 1990 to 1994. The conventional comfortable temperature range 63T (see Figure 4) does not include the temperature range where the room temperature is above 23°C and below 25°C and the floor surface temperature is above 25°C and below 31°C (the dotted part in Fig. 5). On the other hand, the comfortable temperature range 63S (see FIG. 5) includes the temperature range (the dotted portion in FIG. 5). In this embodiment, the temperature range (the dotted portion in FIG. 5) is also included in the comfortable temperature range 63S (see FIG. 5) based on the knowledge that the user in the living room 104 feels comfortable. In addition, in the above-mentioned operation under the floor heating alone operation condition, even if the room temperature and the floor surface temperature reach the comfortable temperature range 63S (see FIG. 5) and are maintained within the comfortable temperature range 63S after reaching the good.

The operation control unit 61B adjusts the heating temperature of the heating unit 20, the flow rate of hot water, and the set temperature based on the measured room temperature, etc., so that the room temperature and floor surface temperature are maintained within the comfortable temperature range 63S. The floor heating device 12 may be controlled to operate under the first combination operating condition that changes at least one of the following. The operation control unit 61B also controls at least one of the air volume, air direction, and set temperature of the air conditioner 13 based on the measured room temperature, etc., so that the room temperature and floor surface temperature are maintained within the comfortable temperature range 63S. The air conditioner 13 may be controlled to operate under a second combined operating condition that changes the air conditioner 13. Note that one of the first combined operating condition and the second combined operating condition may be an operating condition that changes the settings of each part.

Further, in this embodiment, the operation control unit 61B sets the heating temperature of the heating unit 20 based on the set temperature of the air conditioner 13 so that the floor surface temperature is maintained within the comfortable temperature range 63S, The floor heating device 12 may be controlled to operate under the first combined operating condition using the heating temperature. For example, the heating temperature of the heating unit 20 can be set based on the set temperature of the air conditioner 13 as follows.

Here, based on the room temperature of the living room 104 and the temperature at which the heating unit 20 heats the flooring 102 (specifically, the temperature of the hot water in the heating unit 20), the flooring material is calculated by the following formula (1). The bed temperature of the floor material 102 (specifically, the floor surface temperature of the floor material 102) can be determined.

Formula (1) Tf=(λ/d・Th+h・Tr)/(λ/d+h)

Each element of the above formula (1) is as follows (see FIG. 6).
Tf = bed temperature [°C] (surface temperature of floor material 102)
λ = Thermal conductivity of flooring material 102 [W/mK]
d = Thickness of flooring material 102 [m]
Th=Hot water temperature of heating section 20 [℃]
h = surface heat transfer coefficient of flooring material 102 [W/m ² K]
Tr=room temperature [℃]

Here, the above formula (1) is based on the following idea. The amount of heat conduction Q1 from the hot water mat 22 to the floor surface of the floor material 102 and the amount of heat transfer Q2 from the floor surface of the floor material 102 into the room are determined by the following equation (2) and the following equation (3). (See Figure 6).

Formula (2) Q1=λ(Th-Tf)/d
Formula (3) Q2=h(Tf-Tr)

In steady state, Q1 and Q2 are equal, so the following equation (4) holds true.

Formula (4) λ(Th-Tf)/d=h(Tf-Tr)

In the above equation (4), λ, d, h, Tr, and Th are given by known or common values, so the bed temperature Tf can be determined using the above equation (1).

In addition, in the various above-mentioned formulas, the units may be appropriately converted between [° C.] and [K] at a temperature such as room temperature based on the following formula (5).

Formula (5) T [℃] = T + 273.15 [K]

Furthermore, by using the above formula (1), once the room temperature of the living room 104 is known, it is possible to set the hot water temperature of the heating unit 20 so that the floor temperature is included in the comfortable temperature range 63S. Become. The room temperature of the living room 104 can be considered as the set temperature (room temperature setting) of the air conditioner 13. In the comfortable temperature range 63S, the lowest comfortable floor temperature is 25°C. The set temperature of the air conditioner 13 is set, for example, by the user performing an input operation on the input unit 64. Note that the temperature setting of the air conditioner 13 may be set by the processor 61 (operation control unit 61B).

In this embodiment, for example, the operation control unit 61B sets the set temperature of the air conditioner 13 to the room temperature of the living room 104 so that the floor temperature becomes 25°C, and sets the temperature of the heating unit 20 based on the above formula (1). The hot water temperature is set, and the floor heating device 12 is controlled to operate under the first combined operating condition based on the hot water temperature.

Further, the operation control unit 61B controls each of the floor heating device 12 and the air conditioner 13 to operate under each of the first combination operation condition and the second combination operation condition based on the selected operation mode. You may go.

Possible driving modes include, for example, energy saving mode, foot comfort mode, intermediate mode, maximum air conditioning mode, and favorite mode.

In the energy saving mode, for example, an operation mode in which the air conditioner 13 is set to 22°C and the floor surface temperature is maintained at 25°C is operated under operating conditions (first combined operating condition and second combined operating condition). It is. In the energy saving mode, the room temperature and the floor surface temperature are in the left side of the comfortable temperature range 63S.

In the foot comfort mode, as an example, the setting temperature of the air conditioner 13 is set to 22° C., and the operation is performed under operating conditions (first combined operating condition and second combined operating condition) in which the floor surface temperature is maintained at 28° C. mode. The foot comfort mode is a mode in which the room temperature and the floor surface temperature are at the center of the comfortable temperature range 63S.

The intermediate mode is an intermediate mode between the energy saving mode and the foot comfort mode, and as an example, the operating condition is such that the set temperature of the air conditioner 13 is 22°C and the floor surface temperature is maintained at 27°C (first combined operation). This is an operation mode in which operation is performed under the following conditions:

The maximum air conditioning mode is an operating mode in which the air volume of the air conditioner 13 is maximized and the air conditioner is operated under operating conditions (first combined operating condition and second combined operating condition) in which the floor surface temperature is maintained at 25°C. The maximum air conditioning mode is used, for example, as a mode for heating the living room 104 more quickly by a user who does not find warm air uncomfortable.

The favorite mode is a mode registered as a driving condition that realizes an environment that the user feels comfortable by performing a registration operation in the environment. Further, a driving mode that is frequently used by the user may be registered as a favorite mode.

<Control processing according to this embodiment>
Next, an example of the control processing according to this embodiment will be described. FIG. 7 is a flowchart illustrating an example of the flow of control processing executed by the control device 60.

This control process is performed by the processor 61 reading out the control program 63A from the storage 63 and executing it. Execution of this control process is started, for example, when the processor 61 acquires an operation instruction to operate at least one of the floor heating device 12 and the air conditioner 13.

As shown in FIG. 7, upon starting this control process, the processor 61 determines whether the acquired operation instruction is a combined operation instruction for operating the floor heating device 12 and the air conditioner 13 in combination. (Step S101).

When the processor 61 determines that the acquired operation instruction is a combined operation instruction (step S101: YES), the processor 61 controls the floor heating apparatus 12 to operate under a predetermined first combined operation condition. Then, the air conditioner 13 is controlled to operate under the second combined operation condition in which the airflow direction of the indoor unit 30 is along the ceiling 108 of the living room 104 (step S102), and the present control process is ended.

Here, under the second combined operating condition, the wind direction of the indoor unit 30 is set to be along the ceiling 108 of the living room 104 from the start to the end of the operation under the second combined operating condition. Further, the direction in which the wind direction of the indoor unit 30 is along the ceiling 108 of the living room 104 is the direction in which the wind direction of the indoor unit 30 is directed most upwardly.

Furthermore, under the second combined operating condition, the air volume of the fan 38 of the indoor unit 30 is set to be a weak wind from the start to the end of the operation under the second combined operating condition. Specifically, in the second combined operation condition, the air volume of the fan 38 is set to the first stage where the air volume is the lowest, or the second stage where the air volume is the second lowest.

Further, in this embodiment, when it is determined that the acquired operation instruction is a combined operation instruction for operating the floor heating device 12 and the air conditioner 13 in combination, the room temperature and the floor surface temperature fall within the comfortable temperature range 63S. Operation control is performed for each of the floor heating device 12 and the air conditioner 13 to operate under each of the first combined operating condition and the second combined operating condition that are maintained within the comfortable temperature range 63S after reaching the temperature range 63S.

Specifically, in this embodiment, the processor 61 sets the heating temperature of the heating unit 20 based on the set temperature of the air conditioner 13 so that the floor surface temperature is maintained within the comfortable temperature range 63S. , the floor heating device 12 is controlled to operate under the first combined operating condition based on the heating temperature.

On the other hand, if the processor 61 determines that the acquired operation instruction is not a combined operation instruction (step S101: NO), the processor 61 determines whether the acquired operation instruction is an operation instruction for operating the floor heating device 12 independently. It is determined whether or not (step S103).

When the processor 61 determines that the acquired operation instruction is an instruction to operate the floor heating apparatus 12 independently (step S103: YES), the processor 61 performs operation control to cause the floor heating apparatus 12 to operate under predetermined independent operation conditions. is performed on the floor heating device 12 (step S104), and the present control process is ended.

When the processor 61 determines that the acquired operation instruction is not an operation instruction to operate the floor heating device 12 independently (step S103: NO), the processor 61 determines that the acquired operation instruction is to operate the air conditioner 13 independently. Then, the air conditioner 13 is controlled to operate under predetermined air conditioner independent operating conditions (step S105), and the present control process is ended.

<Actions and effects according to this embodiment>
In the present embodiment, when the processor 61 acquires a combined operation instruction to perform a combined operation of the floor heating device 12 and the air conditioner 13, the processor 61 controls the operation of the floor heating device 12 and the air conditioner 13 to operate under a predetermined first combined operation condition. The air conditioner 13 is controlled to operate under the second combination operating condition in which the airflow in the living area of the living room 104 has a wind speed of less than 0.2 m/s.

In this way, in order to control the air conditioner 13 to operate under the second combined operation condition in which the airflow in the living area of the living room 104 has a wind speed of less than 0.2 m/s, the airflow from the indoor unit 30 is controlled. The influence is less likely to be exerted on the user, and the user's comfort is improved. Further, a decrease in the user's sensible temperature is suppressed.

Further, according to the present embodiment, even if the airflow in the living area of the living room 104 has a wind speed of less than 0.2 m/s, the floor heating device 12 warms the flooring 102 of the living room 104, so the entire living room 104 is heated. A circulating flow is generated, and the entire living room 104 including the floor surface temperature is heated faster than when the floor heating device 12 is operated alone. Therefore, energy saving can be achieved.

Conventionally, it was thought that in order to quickly warm up the living room 104, it was necessary for the airflow in the living area of the living room 104 to have a wind speed of 0.2 m/s or more, but in this embodiment, the floor heating device 12 and It has been found that when operated in combination with the air conditioner 13, the living room 104 can be sufficiently warmed even if the airflow in the living area has a wind speed of less than 0.2 m/s. Furthermore, by setting the airflow in the living area to a wind speed of less than 0.2 m/s, it is possible to suppress a decrease in the user's sensible temperature due to the airflow, and therefore it is possible to maintain a low temperature range in which the user feels comfortable.

Therefore, according to this embodiment, it is possible to achieve both energy saving and user comfort.

Further, in the present embodiment, when the processor 61 obtains a combined operation instruction to perform a combined operation of the floor heating device 12 and the air conditioner 13, the processor 61 controls the operation to operate under a predetermined first combined operation condition. The air conditioner 13 is controlled to operate under the second combined operation condition in which the airflow direction of the indoor unit 30 is along the ceiling 108 of the living room 104.

In this way, since the air conditioner 13 is controlled to operate under the second combined operation condition in which the airflow direction of the indoor unit 30 is along the ceiling 108 of the living room 104, the influence of the airflow from the indoor unit 30 is reduced. However, the user's comfort is improved.

Further, according to the present embodiment, even if the airflow direction of the indoor unit 30 is directed along the ceiling 108 of the living room 104, the floor heating device 12 warms the flooring 102 of the living room 104, so a circulation flow occurs throughout the living room 104. The entire living room 104 including the floor surface temperature is heated faster than when the floor heating device 12 is operated alone. Therefore, energy saving can be achieved.

Therefore, according to this embodiment, it is possible to achieve both energy saving and user comfort.

Further, under the second combined operating condition, the wind direction of the indoor unit 30 is set to be along the ceiling 108 of the living room 104 from the start to the end of the operation under the second combined operating condition.

Therefore, from the start to the end of the operation under the second combined operation condition, the influence of the airflow from the indoor unit 30 is less likely to affect the user, and the user's comfort is improved.

Further, the direction in which the wind direction of the indoor unit 30 is along the ceiling 108 of the living room 104 is the direction in which the wind direction of the indoor unit 30 is directed most upwardly. Therefore, the influence of the airflow from the indoor unit 30 is less likely to affect the user, and the user's comfort is improved.

Furthermore, under the second combined operating condition, the air volume of the fan 38 of the indoor unit 30 is set to be a weak wind from the start to the end of the operation under the second combined operating condition. Therefore, the influence of the airflow from the indoor unit 30 is less likely to affect the user, and the user's comfort is improved. Moreover, by setting the air volume of the indoor unit 30 to a weak wind from the start to the end of the operation under the second combined operation condition, the power consumption of the air conditioner 13 can be suppressed, so that energy saving can be achieved.

Specifically, in the second combined operation condition, the air volume of the fan 38 is set to the first stage where the air volume is the lowest, or the second stage where the air volume is the second lowest. Therefore, the influence of the airflow from the indoor unit 30 is less likely to affect the user, and the user's comfort is improved. Furthermore, by setting the air volume of the indoor unit 30 to the first stage where the air volume is the weakest, or the second stage where the air volume is the second weakest, the power consumption of the air conditioner 13 can be suppressed, thereby saving energy. I can do it.

<Evaluation>
The energy saving and user comfort effects of the configuration according to this embodiment were evaluated.

[Example 1]
In the air conditioner 13, the set temperature was set to 19° C., the louver 39 was set at the uppermost position, and the air volume of the fan 38 was set to the first stage, which is the weakest. In addition, at the uppermost position of the louver 39, the wind direction of the indoor unit 30 is along the ceiling 108 of the living room 104, and the wind direction of the indoor unit 30 is the direction facing the uppermost side. Further, in the floor heating device 12, a cycle was performed in which warm water at 40° C. was circulated at 6-minute intervals for 14 minutes in the heating unit 20.

[Example 2]
In the air conditioner 13, the set temperature was set to 22° C., the louver 39 was set at the uppermost position, and the air volume of the fan 38 was set to the first stage, which is the weakest. In addition, at the uppermost position of the louver 39, the wind direction of the indoor unit 30 is along the ceiling 108 of the living room 104, and the wind direction of the indoor unit 30 is the direction facing the uppermost side. Further, in the floor heating device 12, a cycle was performed in which warm water at 40° C. was circulated for 8.5 minutes at 11.5 minute intervals in the heating unit 20.

[Comparative example]
The floor heating device 12 was operated independently with a set temperature of 21°C.

[Evaluation method]
In Examples 1, 2, and Comparative Example, the arrival time from the start of operation until the room temperature and floor surface temperature reach the comfortable temperature range 63S, and the arrival time from the start of operation until the room temperature and floor surface temperature reach the comfortable temperature range 63S The cumulative energy consumption until

[Evaluation results]
In the comparative example, as shown in FIG. 8, the time from the start of operation until the room temperature and floor surface temperature reached the comfortable temperature range 63S was about 79 minutes. On the other hand, in Example 1, as shown in FIG. 9, the arrival time was about 23 minutes. Further, in Example 2, as shown in FIG. 10, the arrival time was about 20 minutes.

Further, in the comparative example, the cumulative energy consumption (energy consumed only by the floor heating device 12) from the start of operation until the room temperature and floor surface temperature reached the comfortable temperature range 63S was about 87 MJ. On the other hand, in Example 1, the cumulative energy consumption (the energy consumption of the floor heating device 12 and the air conditioner 13) was about 75 MJ. Further, in Example 2, the cumulative energy consumption (energy consumption of the floor heating device 12 and the air conditioner 13) was approximately 67 MJ. As described above, in Examples 1 and 2, compared to the comparative example, it is possible to save energy and provide user comfort.

<Modified example of control processing>
In this embodiment, the second combination operation condition in which the airflow in the living area of the living room 104 has a wind speed of less than 0.2 m/s is a second combination operation condition in which the wind direction of the indoor unit 30 is in the direction along the ceiling 108 of the living room 104. Although operating conditions are used, the present invention is not limited thereto. For example, the second combination operation condition in which the airflow in the living area of the living room 104 has a wind speed of less than 0.2 m/s may be a second combination operation condition in which the air volume of the indoor unit 30 is a weak wind. Under this condition, the wind direction of the indoor unit 30 does not matter. That is, in this condition, for example, the wind direction of the indoor unit 30 is in a downward direction (for example, the louver 39 is at the lowest position), or the wind direction of the indoor unit 30 is automatically adjusted. Good too.

Further, in the present embodiment, under the second combination operation condition, the wind direction of the indoor unit 30 is set along the ceiling 108 of the living room 104 from the start to the end of the operation under the second combination operation condition, but this is not limited to this. I can't do it.

For example, in the second combined operating condition, the wind direction of the indoor unit 30 may be set along the ceiling 108 of the living room 104 during a part of the operation under the second combined operating condition. Therefore, for example, even if the wind direction of the indoor unit 30 is set along the ceiling 108 of the living room 104 from the start of operation under the second combined operation condition, and the wind direction of the indoor unit 30 is changed to a different direction during the operation, good. For example, when starting the operation under the second combination operation condition, the wind direction of the indoor unit 30 may be set in a direction different from the direction along the ceiling 108 of the living room 104 (e.g., vertically downward). The wind direction of the indoor unit 30 may be set along the ceiling 108 of the living room 104 from the middle to the end.

Further, in the present embodiment, the air volume of the fan 38 of the indoor unit 30 is set to be a weak wind from the start to the end of the operation under the second combination operation condition under the second combination operation condition, but the present invention is not limited to this.

For example, in the second combined operating condition, the air volume of the indoor unit 30 may be set to a weak wind during a part of the period of operation under the second combined operating condition. Therefore, for example, the air volume of the indoor unit 30 may be set to a weak wind from the start of the operation under the second combined operation condition, and the air volume of the indoor unit 30 may be increased during the operation. Further, for example, at the start of operation under the second combination operation condition, the air volume of the indoor unit 30 is set to be stronger than the weak wind, and from the middle to the end of the operation under the second combination operation condition, the air volume of the indoor unit 30 is set to a weak wind. You can also use it as Furthermore, in the second combined operating condition, the air volume of the indoor unit 30 may be set to be stronger than the weak wind from the start to the end of the operation under the second combined operating condition.

Further, in the present embodiment, the direction in which the wind direction of the indoor unit 30 is along the ceiling 108 of the living room 104 is the direction in which the wind direction of the indoor unit 30 is directed most upwardly, but the direction is not limited to this. The direction in which the wind direction of the indoor unit 30 is along the ceiling 108 of the living room 104 may be the direction in which the wind direction of the indoor unit 30 faces the second or third highest position.

Further, in the present embodiment, when the processor 61 acquires a combined operation instruction for operating the floor heating device 12 and the air conditioner 13 in combination, the processor 61 controls the operation control based on the comfortable temperature range 63S for the floor heating device 12 and the air conditioner. Although this is performed for each of the devices 13, the present invention is not limited thereto. Operation control may be performed using a temperature range different from the comfortable temperature range 63S (for example, the conventional comfortable temperature range 63T).

<Other modifications of control processing>
When the operation control unit 61B acquires the combined operation instruction, the operation control unit 61B performs a first combined operation in which the room temperature and floor surface temperature reach the comfortable temperature range 63S (see FIG. 5) and are maintained within the comfortable temperature range 63S after reaching the comfortable temperature range 63S. Although the operation control is performed for each of the floor heating device 12 and the air conditioner 13 to operate under each of the conditions and the second combined operation condition, the present invention is not limited to this.

Here, in the combined operation of the air conditioner 13 and the floor heating device 12, unlike the independent operation of the floor heating device 12, airflow is generated, so it is conceivable that the user's perceived temperature decreases due to the influence of the airflow.

Therefore, for example, when the acquisition unit 61A acquires a combined operation instruction based on the operation condition A in which the wind speed in the living area of the living room 104 is equal to or higher than a predetermined speed, the operation control unit 61B performs the operation shown in FIG. 11. After shifting the comfortable temperature range so that the room temperature is higher than the set temperature range of the room temperature (see broken line), the operation control is performed for each of the floor heating device 12 and the air conditioner 13. It's okay.

Here, the "living area in the living room 104" is the area where the user exists in the living room 104, for example, the area from the floor 106 to 1800 mm above the floor. Further, the "wind speed in the living area" is defined as the wind speed in the area from the floor surface 106 to 1800 mm above the floor, for example, the wind speed measured at a height of 1100 mm above the floor. The above-mentioned "predetermined speed" is, for example, 0.2 m/s (second). Examples of operating condition A include a case where the wind direction by the louver 39 is set to automatic adjustment regardless of the air volume, and a case where the louver 39 is set to a stage other than the highest position among the five stages. is possible.

Further, the comfortable temperature range may be shifted in stages depending on the room temperature and wind speed. For example, in the case of a first wind speed (e.g. 0.2 m/s) at a predetermined room temperature, the comfortable temperature range is shifted higher than the first predetermined temperature, and a second wind speed faster than the first wind speed (e.g. 0.3 m/s), the comfortable temperature range is shifted to a second temperature higher than the first temperature, and when the third wind speed is faster than the second wind speed (for example, 0.4 m/s), the comfortable temperature range is shifted to a higher value. may be shifted to a third temperature higher than the second temperature.

Specifically, as an example, at a room temperature of 23° C., it is possible to change the shift width according to the wind speed as follows.
Shift width 1.3℃ at wind speed 0.3m/s
At a wind speed of 0.4 m/s, shift width is 1.7°C
At wind speed of 0.5m/s, shift width 2.0℃
At a wind speed of 0.6m/s, shift width is 2.3℃
At a wind speed of 0.7 m/s, shift width is 2.5°C

In this way, by shifting the comfortable temperature range and performing the operation control on each of the floor heating device 12 and the air conditioner 13, the wind speed in the living area of the living room 104 is adjusted to a predetermined speed or higher. Even when the floor heating device 12 and the air conditioner 13 are operated under the operating conditions, the user's comfort is improved.

Further, the operation control unit 61B does not shift the comfortable temperature range when the acquisition unit 61A acquires a combined operation instruction based on an operation condition in which the wind speed in the living area of the living room 104 is less than a predetermined speed. , the operation control may be performed for each of the floor heating device 12 and the air conditioner 13.

Therefore, even when the floor heating device 12 and the air conditioner 13 are operated under operating conditions in which the wind speed in the living area of the living room 104 is less than a predetermined speed, the user's comfort is improved.

Note that an example of the comfortable temperature range is not limited to the comfortable temperature range 63S shown in FIG. 5, but may be the conventional comfortable temperature range 63T shown in FIG. 4.

<Modified example of heating section 20>
In the present embodiment, the heating unit 20 is able to adjust the amount of heating heat for the flooring 102 by changing the heating temperature and flow rate of hot water circulating in the circulation pipe 26, but this is not limited to this. . For example, the heating unit 20 may be configured to adjust the amount of heat for heating the flooring 102 by changing either the heating temperature or the flow rate of the hot water circulating in the circulation pipe 26, or In addition to or in place of the flow rate, the amount of heating heat for the flooring 102 may be adjusted based on other conditions.

In this embodiment, the heating unit 20 is of a hot water type, but is not limited to this. The heating unit 20 may be of an electric type. In the electric heating section, for example, a configuration may be considered in which heating is performed by applying electricity to a heating element disposed below the flooring 102. In this configuration, for example, the amount of heat for heating the flooring 102 can be adjusted by the power supplied to the heating element.

The present invention is not limited to the embodiments described above, and various modifications, changes, and improvements can be made without departing from the spirit thereof. A plurality of the above-mentioned modifications may be combined as appropriate.
