    Specifically, as indicated by solid arrows in FIGS. 2 to 4, in the head side air conditioner (30), the air on the head side of the sleeping person is passed through the first ventilation grill (21a) of the head board (20). Then, it is taken into the lower casing (52) from the use side suction port (43b) of the duct member (40), cooled by the use side heat exchange section (92) of the heat source unit (90), and a predetermined low temperature (Tf− Δt) conditioned air. The conditioned air passes through the use-side fan (95) and flows out from the use-side outlet (42a) of the duct member (40) toward the upper side of the sleeping person's head. The conditioned air that has flowed out flows from the upper side of the sleeping person downward to the lower side as shown by the solid line arrow in FIG. 4 and is sucked again from the use side suction port (43b) of the duct member (40). . That is, a short circuit region of conditioned air having a predetermined low temperature (Tf−Δt) is formed on the sleeping person's head side. Thereby, the head side of the sleeping person is reliably kept at a predetermined low temperature (Tf−Δt).

    As described above, the indoor air conditioner (10) maintains most of the bedroom (R) including the bedside of the sleeping person at the set temperature Tf, while the head side air conditioner (30) The sleeping person's head is locally maintained at a predetermined low temperature (Tf−Δt), and a temperature distribution of “head cold foot heat” is formed around the sleeping person.

    Also, in the exhaust heat side passage (84) of the head side air conditioner (30), as shown by the dotted arrows in FIGS. 2 to 4, the air in the bedroom (R) is transferred to the back plate (20) of the headboard (20). 22) is taken in from the exhaust heat side suction port (71a) via the second ventilation grille (22a), and is heated by the exhaust heat side heat exchange section (93). The heated air flows between the transpiration plates (94d) of the transpiration plate unit (94) to evaporate the drain absorbed by the transpiration plates (94d). Thereafter, the heat-treated air flows out from the exhaust heat side blower outlet (73a) through the exhaust heat side fan (96) together with the vapor of the drained drain, and flows into the side plate (23) of the headboard (20). Outflow from the third ventilation grille (23a).

-Effect of Embodiment 1-
In the air conditioning system (1), the room air conditioner (10) sets the sleeping room (R) to a set temperature Tf suitable for “foot heat”, while the head side air conditioner (30) uses the head side of the sleeping person. Since the temperature is locally lower than the set temperature Tf (Tf−Δt), it is suitable for the comfort of each part of the human body around the sleeping person without providing a closed space such as a sleeping capsule. A temperature distribution of “Cary Cold Foot Heat” can be formed. Thereby, the sleeper can sleep in a comfortable air-conditioning environment without feeling psychological pressure.

    In addition, the duct member (40) of the head side air conditioner (30) has a use side suction port (43b) below the use side air outlet (42a), so that a predetermined low temperature is applied to the sleeping person's head side. A short circuit region of conditioned air of (Tf−Δt) can be formed. Thereby, a sleeping person's head side can be made into a local low-temperature area | region reliably.

    Moreover, since the said head side air conditioner (30) was accommodated in the bed (15), a head side air conditioner (30) does not become obstructive in a bedroom (R). In the present invention, the air conditioning device on the leg side that has been housed in the bed, such as a conventional sleeping capsule, is substituted by the indoor air conditioning device (10), so only the head air conditioning device (30) is provided on the bed.

Then, control is performed so that conditioned air having a temperature (T2−Δt) (for example, 25 ° C.) lower than the second set temperature T2 by a predetermined temperature Δt is supplied to the sleeping person's head.

    Further, when a third set temperature T3 (for example, 31 ° C.) higher than the first set temperature T1 is input to the normal operation unit (102), for example, when the sleeper feels cold during sleep, the normal operation unit (102) is input. 102) controls the indoor air conditioner (10) to supply conditioned air of the third set temperature T3 to the bedroom (R). On the other hand, a notification signal of the third set temperature T3 output from the normal operation unit (102) is input to the sleep operation unit (101). The sleep operation unit (101) includes the head-side air conditioner (30). Then, control is performed so that conditioned air having a temperature (T3−Δt) (for example, 27 ° C.) lower than the third set temperature T3 by a predetermined temperature Δt is supplied to the sleeping person's head.

    In this way, the sleeping bedroom (R) is maintained at the set temperature T set by the sleeping person or the like, while the sleeping person's head side is a temperature (T−Δt) lower than the set temperature T by the predetermined temperature Δt. It can be. That is, the leg side of the sleeping person is kept at the set temperature T, and the head side of the sleeping person is kept at the temperature (T−Δt), and a temperature distribution of “head cold foot heat” is formed.

    The sleeping operation unit (101) may control the head-side air conditioner (30) without receiving a signal of the set temperature T from the normal operation unit (102).

    For example, while the normal operation unit (102) controls the operation of the indoor air conditioner (10), an indoor thermometer (not shown) is provided in the sleeping room (R), and the sleeping operation unit (101) The side air conditioner (30) may be controlled so as to supply conditioned air having a temperature (T′−Δt) lower than the measurement temperature T ′ of the indoor thermometer by a predetermined temperature Δt. Further, the sleep operation unit (101) controls the head-side air conditioner (30) so that the head side of the sleeper becomes a predetermined low temperature (T-Δt) set by the input of the sleeper or the like. Also good. That is, a set temperature T is input to the normal operation unit (102) in advance by a sleeping person or the like, while a temperature (T−Δt) lower than the set temperature T is input to the sleep operation unit (101). Then, the sleeping operation unit (101) controls the head-side air conditioner (30) to supply conditioned air having a predetermined low temperature (T-Δt) set by input to the sleeping person's head. Good.

    Other configurations, operations, and effects are the same as those of the first embodiment.
