Description

Technical Field

[0001] The present disclosure relates to an air conditioning system. Background Art

[0002] Humans have biological rhythms such as circadian rhythms. For example, in the case of circadian rhythms, physiological phenomena such as body temperature and hormone balance change in a cycle of approximately 24 hours. Disruption of biological rhythms can lead to disruption of life rhythms (sleep or activity), which has been confirmed in both children and adults.

[0003] As three factors regulating biorhythm disturbance, light, diet and melatonin have attracted much attention, but in recent years, the importance of thermal environment has also been pointed out. Patent Document 1 discloses an air conditioning control system that creates a thermal environment based on the biorhythm of the day.

[0006] Patent Document 1: Japanese Patent Publication No. 10-148371 Summary of the invention

[0007] -Technical problem to be solved by the invention-

[0008] The air conditioning control system of Patent Document 1 performs temperature control of the air conditioner based on changes in heat release, not based on the biorhythm of a person in the indoor space to be air conditioned.

[0009] The present disclosure aims to provide an air conditioning system that controls a thermal environment according to the biorhythm of a user in a target space.

[0010] -Technical solutions to solve technical problems-

[0011] The first aspect relates to an air conditioning system that performs air conditioning on an object space S, the air conditioning system comprising a detection unit 54, an estimation unit 62 and a control unit C2, the detection unit 54 detects a physiological quantity of an object user E in the object space S, the estimation unit 62 estimates the biorhythm of the object user E based on the physiological quantity, and the control unit C2 controls the thermal environment of the object space S in synchronization with the biorhythm estimated by the estimation unit 62.

[0012] In the first aspect, the thermal environment of the object space S can be controlled according to the biorhythm of the user E. For example, when the user E is an infant, the thermal environment of the object space S can be controlled to be synchronized with the biorhythm of the infant. By performing thermal control in this way, the infant can get a good sleep.

[0013] According to a second aspect, in addition to the first aspect, the air conditioning system further includes an input unit 64 , and the age information or age-in-month information of the user E is input into the input unit 64 .

[0014] In the second aspect, the age information or age-in-month information of the user E can be used for controlling the thermal environment.

[0015] According to a third aspect, in addition to the second aspect, the control unit C2 determines abnormality of the biological rhythm estimated by the estimation unit 62 based on the age information or age in months of the user E.

[0016] In the third aspect, the biorhythm of the subject E can be compared with a standard biorhythm of the age or age in months of the subject E to determine abnormality of the biorhythm of the subject E.

[0017] According to a fourth aspect, based on any one of the first to third aspects, the estimating unit 62 estimates the sleep depth of the subject E based on the physiological quantity, and the control unit C2 adjusts the temperature range of the target space S based on the sleep depth of the subject E.

[0018] In the fourth aspect, for example, for infants who sleep during the day and at night, the sleep depth during the day and at night is different, so the temperature range of the target space S can be adjusted according to the sleep depth, thereby allowing the user E to get a good sleep.

[0019] According to a fifth aspect, in addition to any one of the first to fourth aspects, the estimating unit 62 estimates the biorhythm of the subject E based on changes in body temperature of the subject E within a predetermined period.

[0020] The biorhythm indicates a periodic change in a physiological quantity. In the fifth aspect, the biorhythm can be estimated with higher accuracy based on a plurality of cycles of the biorhythm within a predetermined period.

[0021] According to a sixth aspect, in addition to any one of the first to fifth aspects, the subject E is a child under 3 years old.

[0022] In the sixth aspect, since the biological rhythm of an infant is not 24 hours, for example, the biological rhythm inherent to the infant can be estimated, and the infant can get a good sleep by thermal control based on the biological rhythm.

[0023] The seventh aspect relates to a baby bedding, comprising the air conditioning system according to any one of the first to sixth aspects.

[0024] In a seventh aspect, for example, an infant incubator and a crib including the air conditioning system of the present disclosure can be provided.

[0025] The eighth aspect relates to an air-conditioning system that performs air conditioning on an object space S. The air-conditioning system includes a detection unit 54, an estimation unit 62, and a control unit C2. The detection unit 54 detects a physiological quantity of an object user E in the object space S, and the estimation unit 62 estimates the biorhythm of the object user E based on the physiological quantity. When the biorhythm estimated by the estimation unit 62 is abnormal, the control unit C2 controls the thermal environment of the object space S to correct the biorhythm of the object user E.

[0026] In the eighth aspect, even if the biorhythm of the subject E is disturbed, the biorhythm can be restored to normal.

[0027] According to a ninth aspect, based on the eighth aspect, the control unit C2 determines whether the amplitude of the biorhythm estimated by the estimating unit 62 is abnormal.

[0028] In the ninth aspect, based on the amplitude of the biorhythm of the user E, the abnormality of the biorhythm is determined.

[0029] In the tenth aspect, based on the ninth aspect, when the control unit C2 determines that the amplitude of the biorhythm estimated by the estimation unit 62 is abnormal, the control unit C2 controls the thermal environment of the object space S so that the amplitude is synchronized with a specified reference rhythm of the biorhythm.

[0030] In the tenth aspect, correction can be performed so that the amplitude of the biological rhythm of the subject E is synchronized with a predetermined reference rhythm.

[0031] According to the eleventh aspect, based on the eighth aspect, the control unit C2 determines whether the cycle of the biological rhythm estimated by the estimating unit 62 is abnormal.

[0032] In the eleventh aspect, the abnormality of the biorhythm of the subject E is determined based on the cycle of the biorhythm.

[0033] In the twelfth aspect, based on the eleventh aspect, when the control unit C2 determines that the cycle of the biological rhythm estimated by the estimation unit 62 is abnormal, the control unit C2 controls the thermal environment of the object space S so that the cycle is synchronized with the prescribed reference rhythm of the biological rhythm.

[0034] In the twelfth aspect, correction can be performed so that the cycle of the biological rhythm of the user E is synchronized with a predetermined reference rhythm.

[0035] According to the thirteenth aspect, based on the eighth aspect, the control unit C2 determines whether the phase of the biological rhythm estimated by the estimating unit 62 is abnormal.

[0036] In the thirteenth aspect, the abnormality of the biorhythm of the subject E is determined based on the phase of the biorhythm.

[0037] In the fourteenth aspect, based on the thirteenth aspect, the user object E includes a first user object E1, a second user object E2 and a third user object E3 living together in the object space S, and the control unit C2 judges the abnormality of the phase of the biorhythm of the first user E1 estimated by the estimation unit 62 based on the phase of the biorhythm of the second user object E2 and the third user object E3 estimated by the estimation unit 62.

[0038] In the fourteenth aspect, for example, the phase of the biorhythm of family members living together is compared with the phase of the biorhythm of the user E, and the abnormality of the biorhythm of the user E can be determined based on the deviation of the phases.

[0039] In the fifteenth aspect, based on the thirteenth or fourteenth aspect, when the control unit C2 determines that the phase of the biorhythm of the user E determined to be abnormal is advanced in time, the control unit C2 adjusts to lower the temperature of the object space S.

[0040] In the fifteenth aspect, the peripheral blood vessels are contracted and the awakening state is maintained by lowering the temperature of the target space S. In this way, the phase deviation of the biological rhythm of the user E can be corrected.

[0041] In the sixteenth aspect, based on the thirteenth or fourteenth aspect, when the control unit C2 determines that the phase of the biorhythm of the user E determined to be abnormal is delayed in time, the control unit C2 adjusts to increase the temperature of the object space S.

[0042] In the sixteenth aspect, the metabolism is increased and the peripheral blood vessels are dilated by raising the temperature of the target space S, and as a result, falling asleep can be promoted. In this way, the phase deviation of the biological rhythm of the user E can be corrected.

[0043] The seventeenth aspect relates to an air conditioning system that performs air conditioning on an object space S, the air conditioning system comprising a storage unit 61, a receiving unit 65 and a control unit C2, the storage unit 61 storing biorhythms corresponding to a person's age, gender or metabolic rate, the receiving unit 65 receiving information indicating the age, gender or metabolic rate of a user E in the object space S, the control unit C2 selecting the biorhythm stored in the storage unit 61 based on the information of the user E received by the receiving unit 65, and controlling the thermal environment to be synchronized with the selected biorhythm.

[0044] In the seventeenth aspect, based on the information of the user E in the target space S, a thermal environment suitable for the biorhythm of the user E can be provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] The following describes the embodiments of the present invention with reference to the accompanying drawings. It should be noted that the following embodiments are merely preferred examples in nature and are not intended to limit the present invention, its application objects or its scope of use. In addition, each configuration of each embodiment, modification, other example, etc. described below can be combined or partially replaced within the scope of the present invention.

[0066] (1) Air conditioning system

[0067] like Figure 1 As shown, the air conditioning system 1 of this embodiment is applied to a user E in an indoor space S. The user E is, for example, a child within 3 years after birth. In this embodiment, the user E is an infant less than 12 months after birth. For infants less than 12 months after birth, the biological rhythm has not yet reached 24 hours. The details of the biological rhythm will be described later.

[0068] The air conditioning system 1 controls the thermal environment of the indoor space S according to the biorhythm of the user E. The indoor space S is an example of the target space S. Specifically, the air conditioning system 1 according to the present embodiment will be described below.

[0069] (2) Air conditioning unit

[0070] like Figure 1 and Figure 2 As shown, the air conditioning system 1 of the present embodiment includes an air conditioning device 10 that performs air conditioning on the indoor space S. The air conditioning device 10 performs air conditioning on the indoor space S.

[0071] The air conditioning device 10 includes an outdoor unit 20 and an indoor unit 30. The outdoor unit 20 and the indoor unit 30 are connected to each other through two connecting pipes (a liquid connecting pipe 11 and a gas connecting pipe 12). In this way, a refrigerant circuit R is formed in the air conditioning device 10. The refrigerant circuit R is filled with a refrigerant. In the refrigerant circuit R, a refrigeration cycle is performed by circulating the refrigerant.

[0072] (2-1) Outdoor unit

[0073] The outdoor unit 20 is arranged outdoors. The outdoor unit 20 includes an outdoor fan 21. The outdoor unit 20 includes a compressor 22, an outdoor heat exchanger 23, a switching mechanism 24, and an expansion valve 25 as elements connected to the refrigerant circuit R.

[0074] The compressor 22 compresses the sucked refrigerant. The compressor 22 discharges the compressed refrigerant. The compressor 22 is an inverter compressor, and the rotation speed (operating frequency) of the compressor 22 is adjusted.

[0075] The outdoor heat exchanger 23 is a fin-tube heat exchanger and performs heat exchange between the refrigerant flowing therein and the outdoor air sent by the outdoor fan 21 .

[0076] The switching mechanism 24 is a four-way reversing valve that changes the flow path of the refrigerant circuit R to switch the cooling operation and the heating operation of the air conditioner 10. The switching mechanism 24 has a first port P1, a second port P2, a third port P3, and a fourth port P4. In the cooling operation, the first port P1 is connected to the fourth port P4, and the second port P2 is connected to the third port P3 ( Figure 2 In heating operation, the first port P1 is connected to the third port P3, and the second port P2 is connected to the fourth port P4 ( Figure 2 dashed line).

[0077] The expansion valve 25 is disposed between the liquid-side end portion of the outdoor heat exchanger 23 and the liquid-side end portion of the indoor heat exchanger 33. The expansion valve 25 is an electronic expansion valve whose opening degree is adjustable.

[0078] (2-2) Indoor unit

[0079] The indoor unit 30 is installed in the indoor space S. The indoor unit 30 is, for example, a wall-mounted indoor air conditioner. The indoor unit 30 includes an indoor heat exchanger 33 and an indoor fan 32. The indoor heat exchanger 33 is connected to the refrigerant circuit R.

[0080] The indoor heat exchanger 33 is a fin-tube heat exchanger and performs heat exchange between the air sent by the indoor fan 32 and the refrigerant.

[0081] The indoor fan 32 is a cross-flow fan. The rotation speed of the indoor fan 32 is variable. In other words, the air volume of the indoor fan 32 is variable.

[0082] The indoor unit 30 has an air inlet 30a and an air outlet 30b. Figure 1 The air is conditioned by the indoor heat exchanger 33 and blown out from the blow-out port 30b ( Figure 1 ).

[0083] (2-3) Sensor

[0084] The air conditioner (10) includes an indoor temperature sensor (41). The indoor temperature sensor (41) detects the temperature (room temperature) of the indoor space (S). The indoor temperature sensor (41) is disposed at the suction port (30a) of the indoor unit (30).

[0085] (2-4) Biosensors

[0086] The air conditioning system 1 of this embodiment includes a biosensor 54. The biosensor 54 detects the skin temperature of the user E in the indoor space S. Skin temperature is an example of a physiological quantity. The biosensor 54 is, for example, a wearable sensor that is integrated with a watch. The biosensor 54 is worn on the wrist of the user E. The biosensor 54 outputs a signal indicating the detected skin temperature of the user E to the control device C described later. The biosensor 54 is an example of a detection unit 54.

[0087] (2-5) Remote control

[0088] The air conditioner 10 includes a remote controller 35. Prescribed information is input to the remote controller 35 according to an operation by a person H. The prescribed information includes heating operation start, cooling operation start, operation stop, etc. The prescribed information input to the remote controller 35 is output to the indoor unit 30. The remote controller 35 constitutes a control device C described later.

[0089] (3) Control device

[0090] like Figure 2 and Figure 3As shown, the air conditioning system 1 of this embodiment has a control device C. The control device C includes a first control device C1, a second control device C2, and a third control device C3. The first control device C1 is provided in the outdoor unit 20. The second control device C2 is provided in the indoor unit 30. The third control device C3 is provided in the remote controller 35. Each control device C includes a microcomputer and a storage device, and the storage device stores software that instructs the microcomputer to operate.

[0091] The control device C controls the operation of various devices of the air conditioning device 10. The control device C is connected to the various devices of the air conditioning device 10 by wire or wirelessly. The control device C includes a storage unit 61, an estimation unit 62, and an operation planning unit 63. In this embodiment, the storage unit 61, the estimation unit 62, and the operation planning unit 63 are provided in the second control device C2. The second control device C2 is an example of the control unit C2.

[0092] The storage unit 61 stores the body temperature of the subject E detected by the biosensor 54 in association with the date and time thereof.

[0093] The estimating unit 62 estimates the biorhythm of the subject E based on the skin temperature detected by the biosensor 54. The biorhythm of the present embodiment is a periodic change or variation in the deep body temperature of the subject E. The estimating unit 62 of the present embodiment estimates the deep body temperature using prescribed information indicating the correlation between the deep body temperature and the skin temperature. The prescribed information may also be an arithmetic expression.

[0094] like Figure 4 As shown, with respect to the biological rhythm, the horizontal axis is time, and the vertical axis is body temperature (deep body temperature). After the body temperature (deep body temperature) gradually rises and reaches the highest temperature (first peak), it gradually decreases and reaches the lowest temperature (second peak), and then rises again. In this way, the biological rhythm changes periodically. In the following description, the first peak and the second peak are sometimes referred to as amplitudes. For example, a relatively large amplitude means that the first peak is relatively high and the second peak is relatively low. In addition, in the following description, the deep body temperature is sometimes referred to as simply body temperature.

[0095] The estimating unit 62 estimates the biorhythm of the user E based on the change in the body temperature of the user E within the prescribed period. Specifically, the estimating unit 62 estimates the average value of the biorhythm of a plurality of cycles within the prescribed period stored in the storage unit 61 as the biorhythm of the user E. For example, the prescribed period is set to 10 days, and assuming that there are 10 cycles of the biorhythm in the past 10 days, the estimating unit 62 estimates the average value of the biorhythm of the 10 cycles as the biorhythm of the user E.

[0096] The operation planning unit 63 formulates an operation plan for the air conditioning device 10 based on the biorhythm estimated by the estimation unit 62. Specifically, the operation planning unit 63 of the present embodiment formulates an operation plan that causes the temperature of the indoor space S to change in synchronization with the biorhythm of the user E. For example, the operation plan is formulated in the following manner: during the period when the body temperature rises toward the first peak in the estimated biorhythm, the room temperature is increased, and during the period when the body temperature falls toward the second peak, the room temperature is decreased. The operation planning unit 63 formulates an operation plan based on each estimated biorhythm. In other words, the operation planning unit 63 formulates an operation plan for the next cycle based on each updated biorhythm. In this way, the second control device C2 controls the thermal environment, i.e., the room temperature, of the indoor space S in synchronization with the biorhythm estimated by the estimation unit 62.

[0097] (4) Operation of air conditioners based on biological rhythms

[0098] Next, use Figure 5 The room temperature control of the indoor space S performed by the air-conditioning apparatus 10 in synchronization with the biorhythm of the user E will be described.

[0099] In step S11 , the second control device C2 estimates the biorhythm of the subject E based on the temperature change information of the subject E over a plurality of days.

[0100] In step S12, the second control device C2 formulates an operation plan based on the biorhythm estimated in step S11. The operation of various devices of the air-conditioning device 10 is planned so that the temperature of the indoor space S changes according to the biorhythm. Specifically, the operation plan is formulated so that the room temperature changes synchronously with the period, amplitude, and phase of the biorhythm of the user E.

[0101] In step S13, the second control device C2 executes the operation of the air conditioning device 10 according to the operation plan formulated in step S12. For example, from the first peak moment to the second peak moment (a period when the body temperature drops), the air conditioning device 10 lowers the room temperature. In this way, the heat on the body surface of the user E is easily released, and as a result, the heat is released from the deep part of the body to the body surface, and the deep body temperature is easily lowered. By lowering the deep body temperature, the user E can get a more comfortable sleep. On the other hand, from the second peak moment to the first peak moment (a period when the body temperature rises), the air conditioning device 10 raises the room temperature. In this way, because the body temperature (deep body temperature) of the user E rises, the user E is easy to wake up. In this way, the room temperature is controlled so that the period, amplitude and phase of the biological rhythm of the user E do not deviate.

[0102] (5) Features

[0103] (5-1) Feature 1

[0104] The air-conditioning system 1 of the present embodiment includes an air-conditioning device 10, a detection unit 54, an estimation unit 62 and a second control unit C2 (control unit). The detection unit 54 detects the body temperature (physiological quantity) of the user E in the indoor space S, the estimation unit 62 estimates the biorhythm of the user E based on the body temperature (physiological quantity), and the second control unit C2 controls the room temperature of the indoor space S to be synchronized with the biorhythm estimated by the estimation unit 62.

[0105] The user E of this embodiment is an infant whose circadian rhythm is less than 24 hours. Here, the body temperature is controlled by the circadian rhythm, that is, it is relatively low in the morning and high in the evening. After entering sleep from the wakeful state, it can be observed that: the brain temperature and metabolic rate decrease, the heat generation decreases, while the sweating increases, and the skin blood vessels dilate, thereby increasing the skin temperature. These are all regulatory responses to the drop in body temperature. In this way, sleep starts from the falling period of body temperature, reaches the lowest point of body temperature and enters the rising period before waking up. The circadian rhythm has the above-mentioned roughly constant cycle.

[0106] The circadian rhythm of body temperature is almost unobservable in the neonatal period, and begins to change from about one month after birth. In recent years, abnormal sleep in infants and young children has become a problem. During the infant and young child period, which is the period of brain development, if the sleep-wake rhythm is not formed normally, the biological clock may deviate, and chronic sleep deprivation may occur. Once chronic sleep deprivation occurs, growth and development disorders may develop.

[0107] Therefore, it is important to provide a warm environment that matches the biological rhythm of infants and young children before a constant circadian rhythm is formed during infancy.

[0108] The air conditioning system 1 of this embodiment controls the room temperature (warm environment) to synchronize with the biorhythm of the user E. For example, the room temperature is lowered from evening to morning, and the room temperature is raised from morning to evening. In this way, by providing a room temperature (warm environment) corresponding to the biorhythm of the infant (user E), it is possible to provide the infant with sleep suitable for growth. In this way, the infant can obtain a normal circadian rhythm, thereby preventing the infant from falling into chronic sleep deprivation.

[0109] In particular, when the air conditioning control is performed in a 24-hour or 12-hour cycle, when the room temperature deviates from the biological rhythm of an infant whose biological rhythm has not yet reached 24 hours, the air conditioning system 1 of this embodiment estimates the biological rhythm (cycle) of each user E and performs air conditioning control in accordance with the biological rhythm, thereby suppressing the room temperature from deviating from the actual biological rhythm of the infant. As a result, it is possible to provide the infant with a comfortable sleep and suppress the occurrence of situations that hinder the normal development of the infant.

[0110] (5-2) Feature 2

[0111] The estimating unit 62 of the air conditioning system 1 of the present embodiment estimates the biorhythm of the user E based on the temperature change of the user E in a predetermined period. By averaging the cycles of a plurality of biorhythms in the predetermined period, a more accurate biorhythm can be estimated.

[0112] (6) Modification of the First Embodiment

[0113] The air conditioning system 1 of this example determines whether the estimated biorhythm is abnormal based on the age or age in months of the user E. Next, a configuration different from the first embodiment described above will be described.

[0114] In the storage unit 61 of the air conditioning system 1 in this example, standard biorhythms corresponding to each age and each month of age are stored. In this example, the biorhythm is referred to as a standard rhythm. The standard rhythm is, for example, an average biorhythm for each age and each month of age. The biorhythm can be a national average or an average for a certain region.

[0115] like Figure 6 As shown, the air conditioning system 1 of this example includes an input unit 64, and the age information or age in months information of the user E is input to the input unit 64. The input unit 64 is provided in the second control device C2. The input unit 64 receives the age information or age in months information of the user E output from the remote controller 35 according to the user's operation.

[0116] The second control device C2 makes an abnormality judgment on the biological rhythm of the user E. Specifically, the second control device C2 makes an abnormality judgment by comparing the estimated biological rhythm of the user E with the standard rhythm of the user E of the same age or the same month. For example, if the deviation of the amplitude of the biological rhythm of the user E relative to the amplitude of the standard rhythm does not fall within the prescribed threshold, it is judged to be abnormal. The same judgment is also made on the period and phase of the biological rhythm. Figure 7 Control of the air conditioning system 1 of this example will be described.

[0117] The second control device C2 estimates the biorhythm of the subject E in step S21 .

[0118] In step S22 , the second control device C2 reads out the standard rhythm from the storage unit 61 based on the age information or month age information input to the input unit 64 .

[0119] In step S23, the second control device C2 compares the biorhythm estimated in step S21 with the standard rhythm read in step S22 to make an abnormality judgment. If the biorhythm is judged to be abnormal ("Yes" in step S23), step S24 is executed. If the biorhythm is not judged to be abnormal ("No" in step S23), step S26 is executed.

[0120] In step S24, the second control device C2 formulates a first operation plan. The first operation plan is an operation plan for adjusting the room temperature so that the estimated biological rhythm reaches the standard rhythm.

[0121] In step S25, the second control device C2 operates the air conditioner 10 according to the first operation plan. In this way, the biorhythm of the user E is corrected to the standard rhythm.

[0122] In step S26, the second control device C2 formulates a second operation plan. The second operation plan is an operation plan for controlling the thermal environment so as to synchronize with the estimated biorhythm.

[0123] In step S27, the second control device C2 operates the air conditioner 10 according to the second operation plan. In this way, the user E can get a more comfortable sleep.

[0124] (7) Second Embodiment

[0125] Next, the configuration of the air conditioning system 1 according to the second embodiment that is different from the first embodiment and its modifications will be described.

[0126] When the biorhythm estimated by the estimating unit 62 is abnormal, the air conditioning system 1 of the present embodiment controls the thermal environment of the indoor space S to correct the biorhythm of the user E. In the present embodiment, the thermal environment refers to room temperature.

[0127] The second control device C2 of this example compares the biorhythm estimated by the estimating unit 62 with a predetermined reference biorhythm to determine abnormality in the biorhythm of the subject E. Specifically, the amplitude, period, and phase of the biorhythm of the subject E are determined to be abnormal.

[0128] like Figure 8As shown, the above-mentioned abnormal judgment is performed by comparing the user E in the indoor space S with the family members living with the user E. That is, in the present embodiment, the rhythm used as the prescribed reference is the biological rhythm of the family members living together. For example, the user E in the indoor space S is set as the first user E1, the second user E2 and the third user E3. The first user E1 is set as the user as the judgment object, and the second user E2 and the third user E3 are set as the family members living with the first user E1. The second control device C2 judges the abnormality of the biological rhythm of the first user E1 estimated by the estimation unit 62 based on the biological rhythm of the second user E2 and the third user E3 estimated by the estimation unit 62. In the present embodiment, the biological rhythm of the family members living together is called the reference rhythm.

[0129] Specifically, it is assumed that the first to third user objects E1 to E3 wear the biosensor 54 respectively. In the storage unit 61 of this example, the body temperature information of each user object E is stored over time. In this way, the estimation unit 62 estimates the biorhythm of each user object E. The estimated biorhythm of the first user object E1 is used as the first biorhythm, the estimated biorhythm of the second user object E2 is used as the second biorhythm, and the estimated biorhythm of the third user object E3 is used as the third biorhythm. In this embodiment, each biorhythm can also be estimated based on the body temperature changes of each user object E within a specified period. Next, the control of the air-conditioning system 1 of this example is described.

[0130] <About abnormal amplitude judgment>

[0131] Below, refer to Fig. 9 The following describes the situation in which abnormality determination of amplitude and correction of biorhythm are performed.

[0132] In step S31 , the second control device C2 acquires the biorhythms (first to third biorhythms) of the first to third subjects E estimated by the estimating unit 62 .

[0133] In step S32, the second control device C2 determines a reference rhythm based on the second biorhythm and the third biorhythm. In this example, the average value of the second biorhythm and the third biorhythm is used as the reference rhythm.

[0134] In step S33, the second control device C2 determines whether the amplitude of the biorhythm estimated by the estimation unit 62 is abnormal. Specifically, when the deviation of the amplitude of the first biorhythm relative to the first peak of the reference rhythm exceeds a specified threshold, or the deviation relative to the second peak is lower than a specified threshold, the amplitude of the first biorhythm is judged to be abnormal. On the other hand, when the deviation of the amplitude of the first biorhythm relative to the amplitude of the reference rhythm falls within a specified threshold, the amplitude of the first biorhythm is judged to be normal. When the amplitude of the first biorhythm is judged to be abnormal ("Yes" in step S33), step S34 is executed. When the amplitude of the first biorhythm is not judged to be abnormal ("No" in step S33), step S36 is executed.

[0135] In step S34, the second control device C2 formulates a third operation plan. The third operation plan is an operation plan for adjusting the room temperature so that the amplitude of the first biological rhythm is synchronized with the amplitude of the reference rhythm. Figure 4 The biological rhythm shown is specifically described as a reference rhythm.

[0136] like Fig.10 As shown, the third operation plan of the air conditioner 10 is formulated to operate in the first biorhythm ( Fig.10 In the case where the amplitude of the first peak (dashed line) is smaller than the amplitude of the reference rhythm (the case where the biological rhythm is flattened), the room temperature is lowered from the midpoint between the first peak and the second peak to the second peak, and the room temperature is raised from the midpoint between the second peak and the first peak to the first peak. According to the third operation plan, during the transition from the first peak to the second peak, heat is released from the body surface of the first user E1, and heat is released from the deep part of the body to the body surface. In this way, the body temperature (deep body temperature) of the first user E1 is easily lowered, and the temperature of the second peak is lower than before ( Fig.10 In addition, according to the third operation plan, during the transition from the second peak to the first peak, the deep part of the body of the first user E1 is heated, resulting in an increase in body temperature (deep body temperature), and the first user E1 is easily awakened and can maintain the awakened state.

[0137] In step S35, the second control device C2 operates the air conditioner 10 according to the third operation plan. In the state where the biorhythm is flattened, it can be expected that the first user E1 has a shallow sleep at night and takes a nap during the day. Therefore, according to the above operation plan, it is possible to make it sleep deeper at night and maintain a wakeful state during the day. In this way, the biorhythm can be normalized.

[0138] In step S36, the second control device C2 formulates a fourth operation plan. The fourth operation plan is an operation plan for adjusting the room temperature so as to synchronize with the estimated first biorhythm.

[0139] In step S37, the second control device C2 operates the air-conditioning device 10 according to the fourth operation plan.

[0140] <About cycle abnormality judgment>

[0141] Below, refer to Fig.11 The following describes the process of determining abnormalities in the cycle and correcting the biorhythm.

[0142] Steps S41 to S42 are the same as the above-mentioned steps S31 to S32, and thus description thereof will be omitted.

[0143] In step S43, the second control device C2 determines whether the period of the biological rhythm estimated by the estimation unit 62 is abnormal. Specifically, when the period of the first biological rhythm is longer or shorter than the period of the reference rhythm by a specified threshold value, the period of the first biological rhythm is judged to be abnormal. On the other hand, when the deviation of the period of the first biological rhythm relative to the period of the reference rhythm falls within a specified threshold value, the period of the first biological rhythm is judged to be normal. When the period of the first biological rhythm is judged to be abnormal ("Yes" in step S43), step S44 is executed. When the period of the first biological rhythm is not judged to be abnormal ("No" in step S43), step S46 is executed.

[0144] In step S44, the second control device C2 formulates a fifth operation plan. In the fifth operation plan, the air conditioner 10 adjusts the room temperature so that the cycle of the first biological rhythm is synchronized with the cycle of the reference rhythm. Figure 4 The biological rhythm shown is specifically described as a reference rhythm.

[0145] like Fig.12 As shown, when the period of the first biological rhythm is shorter than the reference rhythm ( Fig.12 In the fifth operation plan (dashed line in (A)), the room temperature is controlled as follows. First, the room temperature is temporarily lowered from just before the first biological rhythm reaches the first peak, the room temperature is raised at the first peak of the reference rhythm, and the room temperature is lowered after a certain period of time. Then, the room temperature is maintained at a low level at the second peak of the first biological rhythm, and the temperature is raised at the second peak of the reference rhythm.

[0146] According to the fifth operation plan, the timing of the temperature drop of the first user E1 is delayed at the first peak of the first biological rhythm, thereby delaying the time of reaching the second peak. In addition, the timing of the temperature rise of the first user E1 is delayed at the second peak, thereby delaying the time of reaching the first peak. As a result, the cycle of the first biological rhythm can be gradually made consistent with the reference rhythm ( Fig.12 (A) Solid line).

[0147] On the other hand, when the cycle of the first biological rhythm is longer than the reference rhythm ( Fig.12 In the fifth operation plan (dashed line in (B)), the room temperature is controlled as follows. First, the room temperature is temporarily raised from before the first peak of the reference rhythm, and then the room temperature is lowered after a certain period of time. Then, the room temperature is raised at the second peak of the reference rhythm.

[0148] According to the fifth operation plan, the body temperature (deep body temperature) of the first user E1 is lowered at the first peak, thereby advancing the time to reach the second peak. In addition, the body temperature of the first user E1 is raised at the second peak, thereby advancing the time to reach the first peak. As a result, the cycle of the first biological rhythm can be gradually made consistent with the reference rhythm ( Fig.12 (B) solid line).

[0149] In step S45, the second control device C2 operates the air conditioning device 10 according to the fifth operation plan. The case where the cycle of the first biorhythm is shorter than the reference rhythm is conceivable, for example, that the first user E1 falls asleep earlier and earlier every day. In this case, by operating the air conditioning device 10 according to the fifth operation plan, it is difficult for the body temperature to drop during the period from the first peak to the second peak, thereby enabling the bedtime to be delayed. In addition, the case where the cycle of the first biorhythm is longer than the reference rhythm is conceivable, for example, that the first user E1 falls asleep later and later every day. In this case, by operating the air conditioning device 10 according to the fifth operation plan, it is easy for the body temperature to drop during the period from the first peak to the second peak, thereby enabling the bedtime to be advanced.

[0150] Steps S46 to S47 are the same as the above-mentioned steps S36 to S37, and thus description thereof will be omitted.

[0151] <About phase abnormality judgment>

[0152] Below, refer to Fig.13 The following describes the situation of determining abnormal phases and correcting biorhythms.

[0153] Steps S51 to S52 are the same as the above-mentioned steps S31 to S32, and thus description thereof will be omitted.

[0154] In step S53, the second control device C2 determines whether the phase of the biorhythm (first biorhythm) estimated by the estimation unit 62 is abnormal. Specifically, it is determined whether the phase of the first biorhythm deviates in time from the phase of the reference rhythm. When it is determined that the phase of the first biorhythm is abnormal ("Yes" in step S53), step S54 is executed. When it is determined that there is no abnormality in the phase of the first biorhythm ("No" in step S53), step S59 is executed. As with the above-mentioned abnormal judgment of amplitude or period, if the deviation of the phase of the first biorhythm relative to the reference rhythm is within a specified threshold, it can be determined that there is no abnormality.

[0155] In step S54, the second control device C2 determines whether the phase of the first biological rhythm is ahead of the phase of the reference rhythm in time. When it is determined that the phase of the first biological rhythm is ahead of the phase of the reference rhythm in time ("Yes" in step S54), step S55 is executed. When it is not determined that the phase of the first biological rhythm is ahead of the phase of the reference rhythm in time ("No" in step S54), it is determined that the phase of the first biological rhythm is behind the phase of the reference rhythm in time, and step S57 is executed.

[0156] In step S55, the second control device C2 formulates a sixth operation plan. The sixth operation plan is an operation plan in which the air conditioner 10 adjusts the room temperature so that the phase of the first biological rhythm is synchronized with the phase of the reference rhythm. Figure 4 The biological rhythm shown is specifically described as a reference rhythm.

[0157] like Fig.14 As shown, the phase of the first biological rhythm is ahead of the phase of the reference rhythm in time ( Fig.14 (A) dashed line). Therefore, the sixth operation plan is formulated to temporarily lower the room temperature from just before the first peak is reached. According to the sixth operation plan, if the room temperature is temporarily lowered from just before the first peak is reached, the blood vessels will contract and inhibit blood flow, so it is difficult for the body temperature to drop, and the timing of reaching the second peak will be later than before. In this way, the timing of reaching the first peak will also be later than before ( Fig.14 (A) Solid line).

[0158] In step S56, the second control device C2 operates the air conditioner 10 according to the sixth operation plan. This operation is performed until the first biorhythm is synchronized with the reference rhythm.

[0159] When the phase of the biological rhythm is advanced in time, it can be thought that the person falls asleep earlier. In this way, by delaying the first peak and the second peak, the phase of the first biological rhythm is delayed in time, and as a result, the time of falling asleep can be postponed. That is, the phase of the first biological rhythm can be made consistent with the phase of the reference rhythm.

[0160] In step S57, the second control device C2 formulates a seventh operation plan. The seventh operation plan is an operation plan in which the air conditioner 10 adjusts the room temperature so that the phase of the first biological rhythm is synchronized with the phase of the reference rhythm. Figure 4 The biological rhythm shown is specifically described as a reference rhythm.

[0161] Specifically, if Fig.14 As shown, the phase of the first biological rhythm is delayed in time from the phase of the baseline rhythm ( Fig.14 (B) dotted line). Therefore, the seventh operation plan is formulated to temporarily raise the room temperature from just before the first peak is reached. According to the seventh operation plan, if the room temperature is temporarily raised from just before the first peak is reached, the blood vessels will dilate and blood flow will be promoted, so the body temperature (deep body temperature) will easily drop, and the timing of reaching the second peak will be earlier than before. In this way, the timing of reaching the first peak will also be earlier than before ( Fig.14 (B) solid line).

[0162] In step S58, the second control device C2 operates the air conditioner 10 according to the seventh operation plan. This operation is performed until the first biorhythm is synchronized with the reference rhythm.

[0163] The delay in the phase of the biological rhythm can be considered as a late sleep. In this way, by advancing the first peak and the second peak, the phase of the first biological rhythm advances in time, and as a result, the sleep time can be advanced. That is, the phase of the first biological rhythm can be made consistent with the phase of the reference rhythm.

[0164] Steps S59 to S60 are the same as the above-mentioned steps S36 to S37, and thus description thereof will be omitted.

[0165] (8) Modification of the Second Embodiment

[0166] like Fig.15 As shown, the air conditioning system 1 of the second embodiment includes a notification unit 55 for reminding the user E to perform a predetermined action. The notification unit 55 is a speaker (not shown) or a display interface (not shown). The notification unit 55 is provided in the indoor unit 30.

[0167] When the second control device C2 determines that the air conditioner 10 has not completely corrected the phase deviation of the user E, the notification unit 55 sends a signal to the user E to remind it to take action to completely correct the phase deviation.

[0168] For example, when the phase of the biorhythm of the user E is ahead of the reference rhythm in time, if the second control device C2 determines that the air conditioning device 10 has failed to correct the biorhythm to the reference rhythm, the notification unit 55 issues a notification to the user E through sound or display to remind the user E to take a nap. The body temperature of the user E drops by taking a nap, so that the phase of the biorhythm can be delayed in time.

[0169] Furthermore, when the phase of the user E is delayed in time, if the second control device C2 determines that the air conditioning device 10 has failed to correct the biorhythm to the reference rhythm, the notification unit 55 issues a notification to the user E through sound or display to remind the user E to take a sauna. The body temperature of the user E rises by taking a sauna, so that the phase of the biorhythm can be advanced in time.

[0170] (9) Third Embodiment

[0171] like Fig.16 As shown, the control device C of this embodiment has a receiving unit 65. The receiving unit 65 receives information indicating the age, gender or metabolic rate of the user E in the target space S. The second control device C2 selects the biorhythm stored in the storage unit 61 based on the information of the user E received by the receiving unit 65, and controls the thermal environment of the indoor space S to be synchronized with the selected biorhythm. The following is a specific description.

[0172] The air conditioning system 1 of this embodiment adjusts the room temperature of the indoor space S according to the user E in the indoor space S so that the user E can achieve the original biorhythm. The original biorhythm is a standard biorhythm set according to age, gender, and metabolic information.

[0173] According to the user's operation, the information of the user E (age, sex, metabolic rate) is input to the receiving unit 65. Regarding age, enter "child" or "adult". The child may also be a school-age child. Regarding metabolic rate, for example, "high" or "low" is selected based on BMI, activity level, weight, etc.

[0174] The storage unit 61 stores the biological rhythm set according to the age, gender, and metabolic information of the user E. Fig.17 As shown in FIG. 1 , the biorhythm is set based on a table showing the relationship between the information of the subject E (age, gender, metabolic rate) and various parameters of the biorhythm (amplitude, peak position, and baseline). Specifically, the amplitude, peak position, and baseline are adjusted based on the standard biorhythm. The baseline in this embodiment refers to the average body temperature of one cycle.

[0175] For example, it is assumed that the information of the subject E is "adult, male, and low metabolism." In this case, the amplitude of the biorhythm is "large", the peak position is "advanced", and the baseline is "low" compared to the standard biorhythm.

[0176] Here, "small" amplitude means that the first peak is 1°C lower than the baseline biorhythm, and the second peak is 1°C higher than the baseline biorhythm. "Large" amplitude means that the first peak is 2°C higher than the baseline biorhythm, and the second peak is 2°C lower than the baseline biorhythm. "Early" peak position means that the peak is 1.5 hours before the baseline biorhythm. "Low" baseline means that it is set to 1°C lower than the baseline biorhythm. Here, peak position refers to the timing or moment of the peaks (first peak and second peak) of a biorhythm (such as a circadian rhythm) in one cycle.

[0177] Below, refer to Fig.18 Control of the second control device C2 in this embodiment will be described.

[0178] In step S61 , the second control device C2 receives various information of the object E.

[0179] In step S62, the second control device C2 determines the biorhythm based on the received information. For example, it is assumed that "adult", "male" and "low metabolism" are input to the input unit 64. In this case, the biorhythm is read from the storage unit 61, and the biorhythm is a biorhythm in which the amplitude is set to "large", the peak position is set to "advanced", and the baseline is set to "low value" according to the standard biorhythm.

[0180] In step S63, the second control device C2 controls the air conditioning device 10 according to the biorhythm selected in step S61. The air conditioning device 10 adjusts the room temperature to match the selected biorhythm. In other words, the air conditioning device 10 adjusts the room temperature to synchronize with the selected biorhythm.

[0181] In this way, for example, it is possible to provide the thermal environment that is supposed to be provided to people who spend time in an indoor space with less temperature fluctuations.

[0182] (10) Modification of the Third Embodiment

[0183] like Fig.19As shown, the input unit 64 of this example receives not only the information of the user E, but also the season information. Winter, summer, or the middle period (spring, autumn) is selected by the user's operation. The baseline is set based on the thermal environment evaluation index (PMV: Predicted Mean Vote). Specifically, the baseline is set to PMV 0.0 to 1.0 (warmer) in winter, to PMV -1.0 to 1.0 in the middle period, and to PMV -1.0 to 0.0 in summer.

[0184] In this way, by air-conditioning the indoor space S based on the biorhythm taking into account not only the information of the user E but also the season information, a thermal environment matching the biorhythm suitable for each season can be provided throughout the year.

[0185] (11) Other Implementation Methods

[0186] In each of the above-mentioned embodiments and their variations, the biological rhythm may also be a periodic variation or change, which includes at least one of the autonomic rhythm (blood pressure, heart rate changes), the endocrine rhythm (hormone amount), the immune rhythm (antibody amount, chemical transmitter amount, location of immune active cells), and the sleep rhythm (brain waves, electromyography, eye movements, respiratory rate) in addition to the body temperature rhythm (deep body temperature, peripheral skin temperature, core body temperature). When the biological rhythm is an autonomic rhythm, the physiological quantity may be blood pressure or heart rate. When the biological rhythm is an endocrine rhythm, the physiological quantity may be a prescribed hormone amount. When the biological rhythm is an immune rhythm, the physiological quantity may be a prescribed amount of chemical transmitters or antibodies, or the location of prescribed immune cells. When the biological rhythm is a sleep rhythm, the physiological quantity may be brain waves, electromyography, eye movements, or respiratory rate.

[0187] In the air conditioning system 1 of the first embodiment, the second embodiment and their modified examples, the estimation unit 62 can estimate the sleep depth of the user E based on the physiological quantity. The second control device C2 adjusts the temperature amplitude of the indoor space S based on the sleep depth of the user E. The physiological quantity is body temperature, brain wave, electromyography, eye movement or respiratory rate. In this way, for example, for infants who sleep during the day and at night, the sleep depth during the day and at night is different, so the temperature amplitude of the indoor space S can be adjusted according to the above sleep depth, so that the infants can get a good sleep.

[0188] The air conditioning system 1 of the first embodiment and its variants can also be applied to baby bedding. For example, a baby incubator (not shown) or a baby crib (not shown) includes the air conditioning system 1. With a baby as the user E, the baby incubator adjusts the temperature inside the baby incubator to synchronize with the biological rhythm of the baby. In addition, the baby incubator adjusts the temperature inside the baby incubator to correct the biological rhythm of the baby in the baby incubator.

[0189] In the first embodiment and its variant, the air conditioning system 1 can also adjust the room temperature of the indoor space S while taking into account the cycle and amplitude of the biorhythm. For example, when the biorhythm of the infant as the user E is a 12-hour cycle, it can be expected that the amplitude of the biorhythm during the day and the amplitude of the biorhythm at night will be different. In this case, it is assumed that the sleep during the day is not as stable as that at night (there are more awakenings in the middle). When the body temperature of the user E received from the biosensor 54 is higher than the estimated body temperature of the biorhythm (that is, the second peak value actually measured is higher than the second peak value of the estimated biorhythm), the second control device C2 determines that the body temperature of the user E has not been sufficiently reduced, and the room temperature rises. Therefore, the body temperature of the user E will temporarily rise. In this way, the blood vessels expand and promote the increase of blood flow, thereby releasing deep heat to the body surface. When the second control device C2 determines that the body temperature of the user E is higher than the fixed value, the second control device C2 controls the air conditioning device 10 to reduce the room temperature. As a result, the deep body temperature will drop, allowing the user E to obtain stable sleep.

[0190] In a modified example of the first embodiment, in addition to the age or age in months, at least one of gender, height, weight, and clothing amount can be input to the input unit 64. By setting a standard rhythm based on the above multiple parameters, multiple standard rhythms can be obtained. As a result, abnormality judgment can be made on the biorhythm of the user E with higher accuracy.

[0191] like Fig. 20 As shown, when the cycle of the first user E1 estimated in the second embodiment is half the cycle of the reference rhythm ( Fig. 20 The second control device C2 formulates an operation plan to increase the room temperature immediately after the initial first peak and to decrease the room temperature just before the next (second) first peak. By increasing the room temperature immediately after the initial first peak, the body temperature drop can be suppressed, so that the initial second peak is higher than the previous one ( Fig. 20 In addition, by lowering the room temperature just before the second first peak appears, the rise in body temperature can be suppressed, making the second first peak lower than the previous one ( Fig. 20 By repeating the above operation, the first second peak value and the second first peak value are gradually reduced, thereby making the cycle of the first user E1 close to the cycle of the reference rhythm.

[0192] In the second embodiment and its modified example, the reference rhythm may not be based on the biorhythm of the family members living together. The reference rhythm may be a standard biorhythm according to age, gender, etc. as in the third embodiment described above.

[0193] In the third embodiment, there may be a plurality of users E in the indoor space S. In this case, the storage unit 61 has biorhythms suitable for all users E in the indoor space S. The biorhythms suitable for all users E are, for example, rhythms obtained by taking the average values ​​of the amplitude, peak position, and baseline of the biorhythms most suitable for each user E. The indoor space S is a classroom, an office, a ward in a hospital, etc. In this way, a warm environment that allows students, office workers, and hospitalized patients to achieve their original biorhythms can be provided.

[0194] In the third embodiment, the information of the user (E) can be at least one of muscle mass, pregnancy, breastfeeding, body surface area, race, local conditions (warm living environment), and metabolic-related diseases (examples of diseases that promote metabolism include hyperfunction of the thyroid, pituitary and adrenal glands, primary hypertension, heart failure, renal insufficiency, leukemia, polycythemia, fever, etc.; examples of diseases that inhibit metabolism include hypofunction of the thyroid, pituitary and adrenal glands, malnutrition caused by diabetes, severe anemia, autonomic nervous system disorders, and comprehensive disorders).

[0195] In a third embodiment, when the subject is a "female", the sexual cycle can be taken into consideration with respect to the baseline.

[0196] In each of the above-described embodiments and their modifications, the air conditioning system 1 may adjust the temperature and humidity of the indoor space S according to the biorhythm. In this case, the air conditioning device 10 includes a humidity sensor (not shown).

[0197] In the above-mentioned embodiments and their variations, the air conditioning system 1 may also include a lighting device (not shown), an audio device (not shown), and an aroma generator (not shown) as devices for controlling the thermal environment. The air conditioning system 1 may also generate illumination, sound, and aroma according to the biorhythm of the user E.

[0198] In the modification of the first embodiment, the second embodiment and its modification, a predetermined threshold value may not be provided for determining abnormality in the amplitude, period or phase of the biorhythm.

[0199] The above embodiments and variations are described, but it should be understood that various changes can be made to their forms and specific circumstances without departing from the subject matter and scope of the claims. As long as the functions of the objects of the present disclosure are not affected, the above embodiments and variations can also be appropriately combined and replaced.
