  The indoor temperature measurement unit 27 measures the indoor temperature Ti of the floor space 7 and is built in the remote controller 26 provided in the floor space 7 in the first embodiment. The indoor temperature measurement unit 27 is connected to the control unit 31 described later via a wired or wireless communication path, and transmits the measured indoor temperature Ti (its data) to the control unit 31. The indoor temperature measurement unit 27 may be provided separately from the remote controller 26 as long as it measures the indoor temperature Ti of the floor space 7, may have another configuration, and is limited to the configuration of the first embodiment. Not.

  The underfloor temperature measuring unit 28 measures the underfloor temperature Tu of the underfloor space 8 and is provided on the air conditioner 11 (its casing) provided in the underfloor space 8 in the first embodiment. The underfloor temperature measurement unit 28 is connected to a control unit 31 described later via a wired or wireless communication path, and transmits the measured underfloor temperature Tu (its data) to the control unit 31. The underfloor temperature measuring unit 28 may be provided separately from the air conditioner 11 as long as it measures the underfloor temperature Tu of the underfloor space 8, may have another configuration, and is limited to the configuration of the first embodiment. Not.

  The human sensor 29 detects whether or not there is a person in the floor space 7, and is provided in the floor space 7 in the first embodiment. The human sensor 29 is connected to a later-described control unit 31 via a wired or wireless communication path, and transmits a signal indicating that to the control unit 31 when a person is present in the floor space 7. The human sensor 29 and the indoor temperature measurement unit 27 are individually provided for each room provided in the floor space 7 and enable execution of floor air conditioning described later and each room in each mode.

  As shown in FIGS. 1 and 2, the air conditioning system 10 is built in an air conditioner 11 and includes a control unit 31 and a storage unit 32. In the air conditioning system 10, power is supplied from a commercial power source to the control unit 31, and the control unit 31 supplies power to the air conditioner 11. The control unit 31 expands the program stored in the connected storage unit 32 or the built-in internal memory on, for example, a RAM (Random Access Memory), thereby appropriately operating the air conditioner 11 in accordance with an operation on the remote controller 26. Overall control. The storage unit 32 stores a control pattern for executing each mode to be described later.

  The control unit 31 obtains the floor surface temperature Tf of the surface of the floor 6 using the indoor temperature Ti measured by the indoor temperature measurement unit 27 and the underfloor temperature Tu measured by the underfloor temperature measurement unit 28. Since the floor portion 6 divides the floor space 7 from the floor space 8, the controller 31 assumes that the floor surface temperature Tf is determined by the indoor temperature Ti and the floor temperature Tu, and the sum of the coefficients is 1. The floor temperature Tf is obtained by setting the degree of influence of the indoor temperature Ti and the underfloor temperature Tu so that In Example 1, the control part 31 calculates | requires floor surface temperature Tf using following Formula (1).

Tf = (A / (2A + t)) × Tu + (1−A / (2A + t)) × Ti (1)
Here, t is the thickness (m) of the floor 6 and A is an arbitrary coefficient. In the first embodiment, the coefficient A is set to 1 or more and 2 or less based on experiments or the like. For this reason, in Example 1, the control part 31 cooperates with the underfloor temperature measurement part 28 and the indoor temperature measurement part 27, and acquires the floor surface temperature Tf of the surface of the floor part 6 (floor surface temperature measurement part (floor surface) Functions as a temperature acquisition unit). The floor surface temperature measuring unit may be a temperature sensor installed on the surface of the floor 6 or inside the floor 6 as long as it measures the floor surface temperature Tf of the surface of the floor 6 and is separated from the surface of the floor 6. A thermopile, a radiation thermometer, an infrared camera, or the like provided at a certain position may be used, and is not limited to the configuration of the first embodiment.

  The control unit 31 can perform the air conditioning on the floor by blowing the conditioned air from the blowout unit 15 on the floor of the air conditioner 11 so as to blow the conditioned air from the blower air supply port 21 to the floor space 7. Moreover, the control part 31 can blow off conditioned air to the underfloor space 8 by blowing off conditioned air from the underfloor blowing part 16 of the air conditioner 11 and perform underfloor air conditioning. Here, since a part of the conditioned air blown out to the underfloor space 8 is blown out from the connection air supply port 22 to the above-floor space 7, the control unit 31 performs the above-floor air-conditioning and under-floor air-conditioning in consideration of this. . In this underfloor air conditioning, the underfloor space 8 can be warmed to warm the floor portion 6 (surface thereof), and floor heating by the air conditioning system 10 is performed.

  Based on the indoor temperature Ti from the indoor temperature measuring unit 27 and the underfloor temperature Tu from the underfloor temperature measuring unit 28, the controller 31 controls the floor temperature so that the indoor temperature Ti and the floor surface temperature Tf become control target temperatures. The temperature and the air volume of the conditioned air blown from the blowout unit 15 and the underfloor blowout unit 16 are controlled. In the first embodiment, the control unit 31 performs PID (Proportional-Integral-Differential) control to set the indoor temperature Ti and the floor surface temperature Tf as control target temperatures.

  In the air conditioning system 10, a plurality of operation modes for controlling the indoor temperature Ti and the floor surface temperature Tf are set during the heating period from autumn to winter to spring, and in the first embodiment, the normal operation mode Mn and An economic priority mode Me, a comfort priority mode Mc, and a sleep preparation mode Ms are set. In each mode, target temperatures of the indoor temperature Ti and the floor surface temperature Tf are set, and the floor surface temperature Tf is set slightly higher than the indoor temperature Ti for each target temperature. Thereby, in each mode, it is possible to prevent only the head side from getting warm and the feet from getting cold, and the burden on the heart can be reduced. In the following, an example of the target temperature of the indoor temperature Ti and the floor surface temperature Tf in each mode will be described, but each target temperature can be appropriately set using the remote controller 26.

  The normal operation mode Mn is set from the viewpoint of ensuring economic efficiency while keeping the floor space 7 at a comfortable temperature during the heating period. In the first embodiment, the indoor normal temperature Tin targeted for the indoor temperature Ti is 21 ° C. The floor surface normal temperature Tfn targeted for the surface temperature Tf is set to 22 ° C. The normal operation mode Mn is used for the resident to spend comfortably when the resident is present.

  The economic priority mode Me is set from the viewpoint that the floor space 7 is not overcooled while ensuring economic efficiency in the heating period. In the first embodiment, the indoor economic temperature Tie targeted for the indoor temperature Ti is set to 16 ° C. The floor surface economic temperature Tfe targeted for the floor surface temperature Tf is set to 17 ° C. The economic priority mode Me is used to prevent a resident who has returned from causing a heat shock even when there is no resident.

  The comfort priority mode Mc is set from the viewpoint of setting the floor space 7 to a comfortable temperature during the heating period. In the first embodiment, the indoor comfortable temperature Tic that is the target of the indoor temperature Ti is 22 ° C., and the target of the floor surface temperature Tf is set. The floor comfortable temperature Tfc is 23 ° C. The comfort priority mode Mc is used for a resident to spend more comfortably when the resident is present.

  The bedtime preparation mode Ms is set from the viewpoint of creating a favorable environment in terms of health and sleep introduction during the heating period, and the bedtime preparation time tp that is a bedtime preparation time zone tzi before the set bedtime ts. The indoor temperature Ti and the floor surface temperature Tf in are set as the indoor preparation temperature Tip and the floor surface preparation temperature Tfp. The indoor preparation temperature Tip and the floor preparation temperature Tfp are set for the purpose of inducing drowsiness, and are higher than the indoor normal temperature Tin and the floor normal temperature Tfn in the normal operation mode Mn. The sleep preparation mode Ms is used to induce sleepiness and improve sleep introduction in a room where the resident is present before the bedtime ts while the resident is healthy.

  In Example 1, the indoor preparation temperature Tip is set to 22 ° C. to 26 ° C. This is because if the temperature exceeds 26 ° C., there is a risk of feeling uncomfortable, and if it is 22 ° C. or higher, the effect of inducing drowsiness is obtained. In addition, the floor surface preparation temperature Tfp is basically set to 2 ° C. to 4 ° C. higher than the indoor preparation temperature Tip. This is because if it exceeds 30 ° C., there is a risk of causing low-temperature burns, and if it is 24 ° C. or more, the effect of inducing sleepiness is obtained.

  The bedtime ts is set at the time when the resident is going to go to bed, and becomes a reference for execution of the bedtime preparation mode Ms and the like. It can be set. The bedtime preparation time zone tzi is a time zone in which the indoor preparation temperature Tip and the floor preparation temperature Tfp are used in order to obtain a healthy and sleepy effect. The bedtime preparation time zone tzi is set to several hours before the bedtime ts, and in the first embodiment, it can be set between 2 hours and 5 hours before the bedtime ts. This is because a minimum of 2 hours is required to obtain the effect of inducing sleepiness and that an effect of inducing sleepiness can be sufficiently expected in 5 hours. Note that the bedtime preparation time zone tzi may be set up to 10 hours as long as it is 2 hours or more. The bedtime preparation time tp is the time before the bedtime preparation time zone tzi from the bedtime time ts, and is the time when the bedtime preparation mode Ms is started in accordance with the bedtime ts.

  In the first embodiment, the control unit 31 executes the bed preparation mode Ms, so that the indoor preparation temperature Tip and the floor preparation temperature Tfp are set in the bed preparation time zone tzi from the bed preparation time tp to the bed time ts as described above. And when it becomes bedtime ts, it switches to economy priority mode Me. This is because it is possible to prevent the room where the resident moves away from the bedtime at the bedtime ts from being unnecessarily warmed. Further, when the sleeping preparation mode Ms is executed in the bedroom, after the resident sleeps, the sleep state can be improved by setting the indoor economic temperature Tie and the floor economic temperature Tfe as described above.

  The control unit 31 basically switches appropriately between the normal operation mode Mn, the economic priority mode Me, the comfort priority mode Mc, and the sleep preparation mode Ms according to a preset time schedule. The setting of each mode can be individually set for each room provided in the floor space 7 by using the above-described operation unit such as the remote controller 26. Note that the control unit 31 may switch between the modes in accordance with an operation on the operation unit, that is, immediately execute a mode selected by the operation.

  The control unit 31 sets the human sensor 29 provided in each room of the floor space 7 to an effective state (ON state), thereby starting the sleep preparation mode Ms depending on whether or not a person exists in the room. And change the end time. That is, when the human sensor 29 does not detect the presence of a person, the control unit 31 does not enter the bed preparation mode Ms even when the bed preparation time tp is reached, and continues the mode performed at that time. Then, after the bedtime preparation time tp, the control unit 31 executes the bedtime preparation mode Ms as soon as the human sensor 29 detects the presence of a person. Even if the control unit 31 according to the first embodiment senses that the human sensor 29 is absent after executing the bed preparation mode Ms, the control unit 31 performs the bed preparation mode Ms until the end time of the bed preparation time zone tzi, that is, the bedtime ts. Do not exit.

  In addition, even when the bedtime ts is reached, the control unit 31 extends the bedtime preparation time zone tzi and continues the bedtime preparation mode Ms when the human sensor 29 senses the presence of a person. Thereafter, when the control unit 31 senses that the human sensor 29 is absent after the bedtime ts, including when the bedtime preparation time zone tzi is extended, the bed preparation mode Ms is ended and the economy priority is given. Switch to mode Me. In addition, after executing the bed preparation mode Ms and when the time during which the human sensor 29 senses absence exceeds a predetermined time (for example, 30 minutes), the control unit 31 goes to the bed preparation mode. Ms may be terminated. In this case, the predetermined time may be set to an arbitrary value using the operation unit.

  In addition, the air conditioning system 10 according to the first embodiment is configured to execute the sleep preparation mode Ms according to the set time schedule regardless of the detection result of the human sensor 29 even when the human sensor 29 is in an effective state. The control priority time zone tzp can be set. Here, for example, with the human sensor 29 in an effective state, the bed preparation time zone tzi is set to 5 hours, and the set control priority time zone tzp is set from 2 hours before the bedtime ts to the bedtime ts. And Then, the air-conditioning system 10 does not execute the bed preparation mode Ms until the resident is present until 3 hours after the bed preparation time tp. The sleep preparation mode Ms is executed regardless of the presence or absence of.

  Next, an example of the set time schedule will be described using the time chart of FIG. In FIG. 3, time is shown on the horizontal axis, and a mode that changes with time is shown above it. In the example of FIG. 3, it is assumed that the resident of the building 1 is set in a living room that is mainly spent at home, and the human sensor 29 is in an invalid state. The bedtime ts is set to 23:00, the bedtime preparation time zone tzi is set to 4 hours, and the bedtime preparation time tp is set to 19:00.

  In the example of FIG. 3, the normal operation mode Mn is set from 4 o'clock to 9 o'clock in consideration of the wake-up time and the going-out time, and the economic priority mode Me is set from 9 o'clock to 12 o'clock in consideration of absence. Yes. Further, the normal operation mode Mn is set from 12:00 to 14:00 in consideration of the return time and the going-out time, and the economic priority mode Me is set from 14:00 to 16:00 in consideration of absence. Further, considering the return time, the normal operation mode Mn is set from 16:00 and the bedtime preparation mode Ms is set at 19:00 of the bedtime preparation time tp. And when it becomes 23:00 of bedtime ts, it will be set as economy priority mode Me, and if it becomes 4:00 again, it will be set as normal operation mode Mn.

  Thereby, the air conditioning system 10 can make the living room of the floor space 7 suitable for the situation of the resident without having to operate the resident of the building 1 every time they go out, go home, go to bed, wake up, etc. It is possible to obtain an effect of inviting sleepiness at bedtime ts while spending comfort and health.

  In the example shown in FIG. 3, even when the human sensor 29 is in an effective state, by setting the set control priority time zone tzp from 19:00 to 23:00 when the sleep preparation mode Ms is scheduled to be executed, A similar operation is performed. In the example shown in FIG. 3, the comfort priority mode Mc is not set, but the comfort priority mode Mc may be set as appropriate.

  Next, an example of the operation when the human sensor 29 is in an effective state will be described using the time chart of FIG. In FIG. 4, it is shown whether the resident existed in the living room used as an object on the time axis. In the example of FIG. 4, each mode is set similarly to the example of FIG. In the example of FIG. 4, it is assumed that the setting control priority time zone tzp is not set.

  In the example of FIG. 4, as in FIG. 3, the sleeping schedule mode Ms is set from 19:00 to 23:00 as a time schedule. Therefore, after the time when the sleep preparation mode Ms is ended according to the detection by the human sensor 29 and until 19:00 of the next day, the same as in FIG. 3 regardless of whether there is a resident or not. Each mode is executed according to the time schedule. In the example of FIG. 4, it is assumed that the resident came home at 20:00 and went to sleep at 1 o'clock. For this reason, although it is set as the sleep preparation mode Ms at 19:00 of the bed preparation time tp, since the resident has not yet returned home and has sensed that the human sensor 29 is absent, The normal operation mode Mn, which has been executed since 16:00, is continued without setting the preparation mode Ms.

  When the resident comes home at 20:00, the human sensor 29 detects the presence of a person, and thus the set bed preparation mode Ms is started. And even if it becomes 23:00 of bedtime ts, since the occupant sensor 29 has sensed the presence of the person because the resident is in the living room, the bedtime preparation time zone tzi is extended and the bedtime preparation mode Ms. Continue. After that, at 1 o'clock, it is sensed that the presence sensor 29 is absent due to the resident leaving the living room, so the economic priority mode Me is set. Thereafter, the normal operation mode Mn is set at 4 o'clock as in FIG.

  As described above, in the living room in which the sleep preparation mode Ms is set, the air conditioning system 10 does not enter the sleep preparation mode Ms even when the resident is absent, and the resident exists. The sleep preparation mode Ms is started from time. For this reason, the air conditioning system 10 can prevent the indoor preparation temperature Tip and the floor preparation temperature Tfp from being higher than the indoor normal temperature Tin and the floor normal temperature Tfn, even though no resident is present. In addition, after the sleep preparation mode Ms is started, the air-conditioning system 10 does not end the sleep preparation mode Ms until the bedtime ts even if the resident is absent. Even in this case, the sleep preparation mode Ms can be continued.

  Further, even if the air conditioning system 10 reaches the bedtime ts, if the resident is present, the bedtime preparation time zone tzi is extended and the bedtime preparation mode Ms is continued, so that the living room passes the set bedtime ts. It is possible to create an environment suitable for the situation of residents living in the city. In addition, the air conditioning system 10 ends the bed preparation mode Ms and extends the bed preparation time zone tzi, that is, if the resident is absent when the bedtime time ts is passed and the sleep preparation mode Ms continues, the economy priority mode is ended. Since it is set to Me, it can prevent continuing the living room which is absent to indoor preparation temperature Tip and floor surface preparation temperature Tfp.

  For these reasons, the air conditioning system 10 can prevent the sleep preparation mode Ms from being started when the user is absent, and can prevent an increase in useless cost. In addition, the air conditioning system 10 can continue the sleep preparation mode Ms when the resident actually sleeps even when the resident is active after the set bed time ts, and is comfortable and healthy. The effect of inviting drowsiness can be obtained with certainty.

  Next, in order to verify that the air conditioning system 10 executes the sleep preparation mode Ms to obtain a healthy and sleepy effect, four examples shown in FIG. 5 (Verification Example 1, Verification Example 2, Comparative Example 1 and Comparative Example 2) were performed. In these four examples, the resident's wake-up time tg is unified at 6 o'clock, the going-out time to 8 o'clock, the return time tb 20:00, and the bedtime ts 23:00.

  Verification Example 1 is a mode in which a room using the air conditioning system 10 is switched to each mode according to a set time schedule. In the verification example 2, in the room using the air conditioning system 10, the human sensor 29 is in an effective state while switching to each mode according to a time schedule substantially similar to that in the verification example 1. In the first comparative example, in the room using the air conditioning system 10, the setting for the sleep preparation mode Ms is eliminated while switching to each mode according to the same time schedule as in the first verification example. In Comparative Example 2, a room using a commercially available air conditioner warms the room with the air conditioner.

  In the time schedule of the verification example 1, the bedtime ts is set to 23:00, the bedtime preparation time zone tzi is set to 4 hours, and the bedtime preparation time tp is set to 19:00. And the time schedule of the verification example 1 is set to the normal operation mode Mn at 5 o'clock before getting up in preparation for the resident's getting up, and the normal operation mode Mn is continued until 9 o'clock so as to be surely warmed until going out, from 9 o'clock. Is the economic priority mode Me because it is absent. Further, the time schedule of the verification example 1 is set to the normal operation mode Mn at 16:00 in preparation for the return of the resident, to the sleep preparation mode Ms at 19:00 of the bedtime preparation time tp, and to the economic priority mode Me at 23:00 of the bedtime time ts. And

  The time schedule of the verification example 2 is substantially the same as that of the verification example 1. However, the comfort priority mode Mc is set from 5:00 to 9:00 in place of the normal operation mode Mn in the verification example 1. In these verifications, as will be described later, it is determined whether or not the effect of inducing drowsiness is obtained by a situation diagnosis performed at 22:30. In comparison, it is considered that there is almost no direct influence by changing to the comfort priority mode Mc. In Verification Example 2, the bedtime preparation time tp is 19:00, but the resident came home at 20:00, so the bedtime preparation mode Ms is started at 20:00. Further, in the verification example 2, since the set bedtime ts has reached 23:00, the user leaves the room and goes to bed. Therefore, the bedtime preparation mode Ms is switched to the economy priority mode Me at the bedtime ts according to the time schedule.

  In the time schedule of Comparative Example 1, since there is no setting of the bed preparation mode Ms, the normal operation mode Mn is set between 19:00 and 23:00, which is the time zone of the bed preparation mode Ms in the verification example 1. In Comparative Example 2, the timer is set so as to warm up from 16:00 prepared for the return time tb to 9:00 on the next day considering the going-out time to. In the comparative example 2, in the timer setting, the indoor temperature Ti (room temperature) is set to 21 ° C. so as to satisfy the same condition as the normal operation mode Mn described above. At this time, the floor temperature Tf was measured to be 19 ° C.

  In this verification, in each example, the situation diagnosis is performed at 22:30, which is 30 minutes before the bedtime (23:00). In this situation diagnosis, a systolic blood pressure (maximum blood pressure) of a resident who has spent in the room set in each example is measured, and a subjective evaluation regarding sleepiness of the resident is obtained. The subjective evaluation is a self-evaluation of how much sleepiness is felt by using a visual analog scale.

  The results of each situation diagnosis were as follows. In Verification Example 1, the median systolic blood pressure is 129 mmHg, and 54% in subjective evaluation. In Verification Example 2, the median systolic blood pressure is 128 mmHg, and 50% in subjective evaluation.

  On the other hand, in Comparative Example 1, the median systolic blood pressure is 131 mmHg, and is −8% in the subjective evaluation. For this reason, in Comparative Example 1, the systolic blood pressure did not change much compared with both verification examples, but drowsiness was lost in the subjective evaluation. In Comparative Example 2, the median systolic blood pressure is 140 mmHg, which is −34% in the subjective evaluation. For this reason, in Comparative Example 2, the systolic blood pressure was increased and the health was inferior compared to both verification examples, and drowsiness was significantly lost in the subjective evaluation. Here, in Comparative Example 1, considering the Comparative Example 2, the systolic blood pressure is almost the same as each verification example, but also in the normal operation mode Mn and the economic priority mode Me other than the sleep preparation mode Ms. This is probably because the floor surface temperature Tf is set slightly higher than the indoor temperature Ti.

  Therefore, in the air conditioning system 10, the bed preparation mode Ms is performed at the bed preparation time tp, the indoor preparation temperature Tip is higher than the indoor normal temperature Tin, and the floor preparation temperature Tfp is higher than the floor normal temperature Tfn. So you can invite sleepiness. Further, in the air conditioning system 10, since the floor surface temperature Tf is set slightly higher than the indoor temperature Ti in each mode including the bedtime preparation mode Ms, an increase in systolic blood pressure can be suppressed and the burden on the body is reduced. Can create a healthier environment.

  The air conditioning system 10 according to an embodiment of the air conditioning system according to the present disclosure can obtain the following functions and effects.

  The air conditioning system 10 measures the indoor surface temperature Ti of the floor space 7 by the indoor temperature measuring unit 27 and measures the floor surface temperature Tf of the surface of the floor 6 by the floor surface temperature measuring unit during the air conditioning control by the air conditioner 11. To do. Then, the air conditioning system 10 includes the normal operation mode Mn in which the indoor temperature Ti is set to the indoor normal temperature Tin and the floor surface temperature Tf is set to the floor normal temperature Tfn, and the bedtime preparation time tp before the set bedtime ts. Until the bedtime ts, the sleep preparation mode Ms can be executed in which the indoor preparation temperature Tip is higher than the indoor normal temperature Tin and the floor preparation temperature Tfp is higher than the indoor preparation temperature Tip and the floor normal temperature Tfn. It is. For this reason, the air-conditioning system 10 can make a resident comfortably by setting it as normal operation mode Mn, and it is healthy and sleep introduction is favorable by setting it to the sleep preparation mode Ms according to the resident's bedtime ts. State.

  In addition, the air conditioning system 10 uses the indoor temperature Ti measured by the indoor temperature measurement unit 27, the underfloor temperature Tu measured by the underfloor temperature measurement unit 28, and the thickness t of the floor 6 and the above formula ( The floor surface temperature Tf is obtained by 1). For this reason, since it is not necessary to provide the apparatus for calculating | requiring the floor surface temperature Tf, the air conditioning system 10 can calculate | require the floor surface temperature Tf with a simple structure, and can adjust the floor surface temperature Tf.

  Furthermore, since the air conditioning system 10 has the floor surface temperature Tf higher than the indoor temperature Ti, the resident can be in a healthy state in any mode. In addition, since the air conditioning system 10 adjusts both the indoor temperature Ti and the floor surface temperature Tf, a comfortable and healthy state can be achieved while lowering the floor surface temperature Tf compared to the case where only floor heating is used. can do. When only floor heating is used, the indoor temperature Ti can be increased by increasing the floor surface temperature Tf. However, in order to warm the indoor temperature Ti, the floor surface temperature Tf is, for example, 30 ° C. This is due to the fact that it may become uncomfortable and cause low-temperature burns.

  When the bedtime ts comes, the air conditioning system 10 executes the economic priority mode Me that sets the floor economic temperature Tfe lower than the floor normal temperature Tfn and the indoor economic temperature Tie lower than the indoor normal temperature Tin. For this reason, the air conditioning system 10 can prevent the resident from moving to the bedroom and unnecessarily warming the room that is absent, and in the case of the bedroom, the sleep state can be improved.

  The air conditioning system 10 is provided with a human sensor 29 that detects whether or not a person is present in the floor space 7, and when the human body sensor 29 does not detect a person when the bed preparation time tp is reached, the sleep preparation mode Ms is set. If the human sensor 29 senses a person without executing it, the sleep preparation mode Ms is executed. For this reason, the air conditioning system 10 can prevent wasteful warming when the resident is absent, and can be in a healthy state with good sleep introduction when the resident is present. In particular, in the first embodiment, when the air conditioning system 10 executes the bed preparation mode Ms once at the bed preparation time tp, even if it is detected that the human sensor 29 is absent, the bed preparation is performed until the bed time ts. The mode Ms is not terminated. For this reason, the air conditioning system 10 can continue the bed preparation mode Ms without interruption after the bedtime preparation time tp, for example, when a resident goes out of the room for a short time and returns to the room, It is possible to ensure a healthy state with good sleep introduction.

  The air conditioning system 10 is capable of setting a setting control priority time zone tzp for executing the bedtime preparation mode Ms when the bedtime preparation time tp comes regardless of the detection result of the human sensor 29. For this reason, the air conditioning system 10 executes the sleep preparation mode Ms in accordance with the preset time schedule in the set control priority time zone tzp, and thus performs the sleep preparation mode Ms as set by the resident in advance. be able to.

  The air conditioning system 10 includes an operation unit (in the first embodiment, the remote controller 26) for performing the sleep preparation mode Ms, and executes the bed preparation mode Ms according to the operation of the operation unit. For this reason, the air conditioning system 10 can start or end the sleep preparation mode Ms according to the resident's request.

  The air conditioning system 10 can set the indoor preparation temperature Tip between 22 ° C. and 26 ° C., and can set the floor preparation temperature Tfp as a value obtained by adding the indoor preparation temperature Tip to a value from 2 ° C. to 4 ° C. Yes. For this reason, the air conditioning system 10 can obtain the effect of inducing drowsiness without causing discomfort or causing low temperature burns.

  The air conditioning system 10 can set the bedtime preparation time tp between 2 hours and 5 hours before the bedtime ts. For this reason, the air conditioning system 10 can perform the sleep preparation mode Ms according to a resident's request, making it possible to obtain the effect of inviting sleepiness with certainty.

  The air conditioning system 10 can individually set the bedtime preparation time tp, that is, the bedtime preparation time zone tzi, for each room of the building 1. For this reason, the air conditioning system 10 can perform the bedtime preparation mode Ms according to the use and request for every room of a resident.

  The air conditioning system 10 can set the bedtime ts individually for each room of the building 1. For this reason, the air conditioning system 10 can perform the bedtime preparation mode Ms according to the demand of each resident's room.

  The building 1 includes an air conditioning system 10. For this reason, the building 1 can make the room where a resident spends a healthy state with favorable sleep introduction.

  Therefore, in the air conditioning system 10 of Example 1 as the air conditioning system according to the present disclosure, it is possible to promote comfortable sleep while suppressing a burden on the body.
