Description

[Technical Field]

[0001] The present invention relates to a technology for an air conditioning system for air conditioning a room. [Background technology]

[0002] Conventionally, technology for an air conditioning system for air conditioning a room has been publicly known, as described in Patent Document 1, for example.

[0003] Patent Document 1 describes a central air conditioning system for conditioning multiple rooms in a building. In this central air conditioning system, air conditioned by an air conditioner is transported to each room by a fan, thereby conditioning each room.

[0004] In such air conditioning systems, a water-connected humidifier has traditionally been installed in the circulation path within the air conditioner to humidify each room. In an air conditioning system equipped with a water-connected humidifier, the air heated by the air conditioner is humidified by the humidifier, and this humidified air is then transported to each room, thereby humidifying each room.

[0005] However, water-connected humidifiers pose a high risk of sanitation management issues, such as scaling and leaks, and require maintenance by specialized contractors. Furthermore, their humidifying capacity is insufficient, making precise humidity control difficult. Thus, installing a water-connected humidifier poses problems in terms of maintenance and humidifying capacity. Even when installing a home humidifier, for example, there are issues with the amount of humidification required when the room temperature in each room is stable.

A staircase 9 leading to the first floor is located on the west side of the toilet 7. A mechanical room 20 and an accessory room 30 are located on the north side of the study 6. Details of the mechanical room 20 and accessory room 30 will be described later.

[0025] As shown in FIG. 2, the first floor of the house 1 is mainly provided with a living / dining / kitchen (LDK) 11, a Japanese-style room 12, a corridor 13, a front door 14, and a washroom 15.

[0026] The main components of the air conditioning system 100 are provided in the machine room 20 and the auxiliary room 30. The machine room 20 and the auxiliary room 30 will be described below with reference to FIGS.

[0027] The machine room 20 is a room in which an air conditioner 120 and an air conditioning unit 130, which will be described later, are installed. The machine room 20 is located on the north side of the study 6, adjacent to the hallway 8. A door 21 for accessing and exiting the machine room 20 is provided on the wall of the machine room 20 adjacent to the hallway 8 (the north wall) (see Figure 3). In addition, a hanging wall 22 is provided on the ceiling of the machine room 20. The hanging wall 22 is located approximately in the center of the machine room 20, with both wall surfaces facing north-south.

[0028] The auxiliary room 30 is a room in which a humidifier 110, described later, is installed. The auxiliary room 30 is located on the north side of the study 6, adjacent to the hallway 8. The auxiliary room 30 is located on the east side of the machine room 20, adjacent to the machine room 20. A door 31 for accessing and exiting the auxiliary room 30 is provided on the wall of the auxiliary room 30 adjacent to the hallway 8 (the north wall) (see Figure 3). As shown in Figure 4, the auxiliary room 30 is provided with a lower storage shelf 32 and an upper storage shelf 33 for storing consumables and the like. The lower storage shelf 32 is placed on the floor of the auxiliary room 30. The upper storage shelf 33 is provided in the ceiling of the auxiliary room 30. A power outlet 34, to which the power cord of the humidifier 110, described later, can be connected, is provided on the inner wall surface on the south side of the auxiliary room 30.

[0029] Next, the configuration of the air conditioning system 100 will be described with reference to FIGS.

[0030] The air conditioning system 100 is a system (central air conditioning system) that conditions the indoor space of each room in the house 1. The air conditioning system 100 mainly includes a humidifier 110, an air conditioner 120, an air conditioning unit 130, a duct 140, an upper door grill 150, a wall grill 160, an air outlet 170, a temperature sensor 180, a damper 190, and a control unit 200.

[0031] The humidifier 110 shown in Figure 4 humidifies an indoor space. The humidifier 110 is provided in the auxiliary room 30. Specifically, the humidifier 110 is placed on the lower storage shelf 32. The humidifier 110 is connected to an outlet 34 via a power cord (not shown). Any type of humidifier can be used as the humidifier 110, and a steam, evaporative, ultrasonic, or hybrid humidifier can be used.

[0032] The humidifier 110 is configured to allow input of a set humidity (a humidity set as a target). The humidifier 110 has a humidity sensor. The humidifier 110 operates when the humidity of the air in the auxiliary chamber 30 is (determined to be) lower than the set humidity based on the detection result of the humidity sensor, so that the humidity of the air reaches the set humidity. The humidifier 110 also stops operation when the humidity of the air in the auxiliary chamber 30 is (determined to be) at the set humidity based on the detection result of the humidity sensor.

[0033] The air conditioner 120 shown in Figures 4 and 5 adjusts the temperature of the air. The air conditioner 120 is provided in the machine room 20. Specifically, the air conditioner 120 is provided on the south side of a hanging wall 22 provided in the machine room 20. The air conditioner 120 is connected to an outdoor unit (not shown) and can circulate a refrigerant between the air conditioner 120 and the outdoor unit. The air conditioner 120 is configured to draw in air from within the machine room 20, adjust the temperature of the air by exchanging heat between the drawn air and the refrigerant, and then discharge the air.

[0034] Air conditioner 120 is configured to allow a set temperature (a temperature set as a target) to be input. Air conditioner 120 can operate (automatically) by automatically adjusting the circulation of refrigerant and the air volume based on the detection results of temperature sensor 180 (described later) so that the air temperature (room temperature) in each room of house 1 becomes the set temperature.

[0035] The air conditioner 120 has a function (so-called thermo-off function) that automatically stops the circulation of refrigerant between the outdoor unit and the air conditioner 120 when the air temperature in the machine room 20 reaches a set temperature (when the room temperature reaches a certain degree of proximity to the set temperature). When the room temperature in the machine room 20 reaches the set temperature, the thermo-off function causes the air conditioner 120 to stop the circulation of refrigerant and automatically reduce the airflow. In other words, the thermo-off function causes the air conditioner 120 to only blow air.

[0036] The air conditioner 120 can change the air volume. The air conditioner 120 may be capable of changing the air volume to any desired volume in a continuous manner, or may be capable of changing the air volume in stages to a predetermined volume. In this embodiment, the air conditioner 120 is capable of changing the air volume in three stages: "weak," which is a very low air volume; "medium," which is a higher air volume than "weak," and "high," which is a higher air volume than "medium." The air volume of the air conditioner 120 is set to "weak" when the thermostat is off, and is set to "medium" or "high" at other times (when the air conditioner is operating).

[0037] The operation of the air conditioner 120 can also be controlled by instructions from the control unit 200, which will be described later.

[0038] 4 and 5 performs air conditioning and air transport. The air conditioning unit 130 is provided in the machine room 20. The air conditioning unit 130 is provided below the air conditioner 120. The air conditioning unit 130 is equipped with a blower fan. By operating the blower fan, the air conditioning unit 130 sucks in air discharged from the air conditioner 120 and discharges the air to the outside of the machine room 20 via a duct 140, which will be described later.

[0039] The air conditioning unit 130 (blower fan) can change the air volume. The air conditioning unit 130 may be capable of continuously changing the air volume to any desired value, or may be capable of changing the air volume in stages to a predetermined value. In this embodiment, the air conditioning unit 130 can change the air volume between three levels: "weak," which is a very low air volume; "medium," which is a higher air volume than "weak," and "high," which is a higher air volume than "medium." The air conditioning unit 130 can operate (automatically) by automatically adjusting the air volume in conjunction with the air conditioner 120. That is, the air volume of the air conditioning unit 130 is set to "weak" when the air conditioner 120 is in thermo-off mode, and is set to "medium" or "high" otherwise.

[0040] 4(b) constitutes an air supply path for sending air from the machine room 20 to each room (room requiring air conditioning) of the house 1. The duct 140 includes a first duct 141 and a second duct 142.

[0041] The first duct 141 is provided to connect the air conditioning unit 130 and each room on the second floor of the house 1. The first duct 141 is formed in a cylindrical shape that allows air to circulate inside. One end of the first duct 141 is connected to the air conditioning unit 130. The first duct 141 is formed to extend from the air conditioning unit 130 to each room on the second floor of the house 1 (more specifically, to each air outlet 170, which will be described later) while bending appropriately.

[0042] The second duct 142 is provided to connect the air conditioning unit 130 to each room on the first floor of the house 1. The second duct 142 is formed in a cylindrical shape that allows air to circulate inside. One end of the second duct 142 is connected to the air conditioning unit 130. The second duct 142 is formed to extend from the air conditioning unit 130 to each room on the first floor of the house 1 (more specifically, to each air outlet 170, which will be described later) while bending appropriately.

[0043] The upper door grille 150 shown in Figures 3 and 4(a) is the part that serves as the air intake for the annex room 30. The upper door grille 150 is formed so that the north wall of the annex room 30 is open. More specifically, the upper door grille 150 is formed above the door 31 of the annex room 30. This allows air to circulate between the corridor 8 and the annex room 30 via the upper door grille 150.

[0044] The wall-side grill 160 shown in FIG. 4 connects the ancillary compartment 30 and the machine compartment 20. The wall-side grill 160 is formed so that the wall between the ancillary compartment 30 and the machine compartment 20 is open. The wall-side grill 160 is formed so that at least a portion of it is located above the humidifier 110. The wall-side grill 160 is also formed so that at least a portion of it is located above the air conditioner 120. The wall-side grill 160 is formed so that the opening area thereof is approximately the same as the opening area of ​​the upper door grill 150.

[0045] The air outlet 170 shown in FIGS. 1 and 2 is an outlet for air sent through the duct 140. The air outlet 170 is provided in the ceiling of each room (room requiring air conditioning) of the house 1. More specifically, the air outlet 170 is provided in the ceiling of the master bedroom 2, the first Western-style room 3, the second Western-style room 4, the study 6, and the hallway 8 on the first floor of the house 1, and in the ceiling of the living-dining-kitchen (LDK) 11, the Japanese-style room 12, the entrance 14, and the bathroom 15 on the second floor of the house 1. The air outlet 170 is connected to the other end (opposite the air conditioning unit 130) of the duct 140 (the first duct 141 and the second duct 142). By providing the air outlet 170 in this manner, air in the machine room 20 (air transported from the air conditioning unit 130 through the duct 140) is supplied to each room through the air outlet 170.

[0046] 1, 2, and 5 measures (acquires) room temperature. The temperature sensor 180 is provided in each room of the house 1 (some of the rooms that require air conditioning, i.e., some of the rooms with air outlets 170). More specifically, the temperature sensors 180 are provided on the walls of the master bedroom 2, the second Western-style room 4, and the hallway 8 on the first floor of the house 1, and on the walls of the living-dining-kitchen (LDK) 11, the Japanese-style room 12, and the bathroom 15 on the second floor of the house 1. This allows the temperature sensors 180 to measure the room temperature in each room of the house 1.

[0047] 5 switches between opening and closing the duct 140 (first duct 141 and second duct 142). The damper 190 is provided for each room, and is capable of switching between allowing and not allowing air to be conveyed to each room.

[0048] 5 is a control panel that controls the operations of the air conditioner 120, the air conditioning unit 130, and the damper 190. The control unit 200 includes a storage unit such as a RAM, a ROM, and an HDD, and an arithmetic processing unit such as a CPU. The control unit 200 stores various types of information, programs, and the like for controlling the operations of the air conditioner 120, the air conditioning unit 130, and the damper 190.

[0049] The control unit 200 is appropriately provided with an operation unit (for example, buttons, keyboard, etc.) that allows various operations to be performed, a display unit (for example, lamps, monitor, etc.) that can display various information, a touch panel that has the functions of an operation unit and a display unit, etc. The control unit 200 is disposed in the machine room 20.

[0050] The control unit 200 is connected to the temperature sensor 180 and can acquire information about the room temperature of each room in the house 1 measured by the temperature sensor 180.

[0051] The control unit 200 is connected to the air conditioner 120, the air conditioning unit 130, and the damper 190, and can control the operation of the air conditioner 120 and the air conditioning unit 130 (switching between on and off, set temperature, air volume, etc.).

[0052] In addition, the control unit 200 can switch the operating modes of the air conditioner 120 and the air conditioning unit 130 between a "normal mode" in which the air conditioner 120 and the air conditioning unit 130 operate automatically, and a "blowing mode" in which the air conditioner 120 is stopped (the air volume is set to "weak") and the air conditioning unit 130 (its blower fan) is forcibly operated.

[0053] In the air conditioning system 100 configured as described above, the air in each room can be heated and humidified by supplying the air in the machine room 20 to each room of the house 1. Hereinafter, the flow of air in the house 1 will be described with reference to FIG.

[0054] As shown in FIG. 6(a), air is taken into the auxiliary room 30 from the corridor 8 through the upper door grille 150. The air in the auxiliary room 30 is humidified by the humidifier 110. This humidified air in the auxiliary room 30 is supplied to the air conditioner 120 through the wall-side grille 160 by the suction force of the air conditioner 120. The air (humidified air) supplied to the air conditioner 120 is heated (temperature-regulated) by the air conditioner 120.

[0055] As shown in FIG. 6(b), the air conditioner 120 discharges heated air, and the discharged air is supplied to the air conditioning unit 130. The air (humidified and temperature-controlled air) supplied to the air conditioning unit 130 is sent to each room by the air conditioning unit 130 (transport fan) via the duct 140 and the air outlet 170. The air sent to each room is transported back to the corridor 8 by a circulation fan or the like (not shown), and is taken back into the auxiliary room 30.

[0056] In this way, the indoor space of each room can be heated and humidified. Also, if a set temperature can be set for each room, the control unit 200 can control the opening and closing of each damper 190 to bring the room temperature of each room close to the set temperature for each room.

[0057] In this way, by providing the air conditioner 120 and the air conditioning unit 130 in the machinery room 20 and providing the humidifier 110 in the auxiliary room 30 that allows air communication between the machinery room 20, it is possible to make the air flow appropriate. Specifically, in the machinery room 20, the air conditioner 120 is provided above the air conditioning unit 130, and the wall-side grill 160 that connects the auxiliary room 30 and the machinery room 20 is provided above the air conditioner 120, so that air flows in the order of the humidifier 110, the air conditioner 120, and the air conditioning unit 130. In other words, it is possible to prevent air humidified by the humidifier 110 from being supplied directly to the air conditioning unit 130 without passing through the air conditioner 120.

[0058] Furthermore, even if the humidifier 110 is installed above the air conditioner 120 in the machine room 20, it is possible to make the air flow in the order of the humidifier 110, the air conditioner 120, and the air conditioning unit 130. However, in this case, the humidifier 110 needs to be installed at a high position, which makes maintenance difficult.

[0059] That is, by providing the air conditioner 120 and the air conditioning unit 130 in the machine room 20, providing the humidifier 110 in the auxiliary room 30 which allows air communication between the machine room 20, and providing the air conditioner 120 above the air conditioning unit 130 in the machine room 20 and providing the wall-side grill 160 which connects the auxiliary room 30 and the machine room 20 above the air conditioner 120, the air flow can be made appropriate and maintenance of the humidifier 110 can be made easy.

[0060] Next, a method for adjusting the temperature and humidity of air in each room of the house 1 using the air conditioning system 100 configured as described above will be described with reference to the flowchart of FIG.

[0061] 7 is executed in seasons when heating and humidification are required, such as winter, etc. The control flow shown in FIG. 7 is repeatedly executed by the control unit 200 at predetermined timings.

[0062] In step S1, the control unit 200 performs operation in the normal operation mode, thereby automatically operating the air conditioner 120 and the air conditioning unit 130. After performing the process of step S1, the control unit 40 proceeds to step S2.

[0063] In step S2, the control unit 200 executes a blowing mode switching flow. The blowing mode switching flow is a flow for switching from the normal mode to the blowing mode. The blowing mode switching flow will be described in detail later. After performing the process of step S2, the control unit 40 proceeds to step S3.

[0064] In step S3, the control unit 200 executes a normal mode switching flow. The normal mode switching flow is a flow for switching from the fan mode to the normal mode. The normal mode switching flow will be described in detail later. After performing the process of step S3, the control unit 40 temporarily ends the control flow shown in FIG. 7.

[0065] The flow of switching the air blowing mode (step S2 in FIG. 7) will be described in detail below with reference to the flowchart in FIG.

[0066] In step S11, the control unit 200 checks the status of the air conditioner 120 and the air conditioning unit 130 (blower fan). Specifically, the control unit 200 acquires current information (operation / stop, set temperature, air volume, etc.) of the air conditioner 120 and the air conditioning unit 130. After performing the process of step S11, the control unit 40 proceeds to step S12.

[0067] In step S12, the control unit 200 acquires the air temperature (room temperature) in each room of the house 1. Specifically, the control unit 200 acquires the measurement results of the temperature sensors 180 provided in each room. After performing the process of step S12, the control unit 40 proceeds to step S13.

[0068] In step S13, the control unit 200 determines whether the room temperature of each room in the house 1 has reached the set temperature and whether 30 minutes have passed since reaching the set temperature. The control unit 200 determines "YES" if all rooms provided with the air outlets 170 satisfy the above conditions.

[0069] If the control unit 200 determines that the room temperature of each room in the house 1 has reached the set temperature and that 30 minutes have passed since the temperature was reached ("YES" in step S13), the control unit 200 proceeds to step S14.

[0070] In step S14, the control unit 200 determines whether the airflow rates of the air conditioner 120 and the air conditioning unit 130 are "low." That is, the control unit 200 determines whether the thermostat of the air conditioner 120 is off.

[0071] When the control unit 200 determines that the airflow rates of the air conditioner 120 and the air conditioning unit 130 are "weak" ("YES" in step S14), the control unit 200 proceeds to step S15.

[0072] Note that if step S13 returns "YES" and step S14 returns "YES", this indicates that the room temperature in each room is stable near the set temperature.

[0073] In step S15, the control unit 200 switches the operation mode of the air conditioner 120 and the air conditioning unit 130 to the fan mode, thereby keeping the air volume of the air conditioner 120 at "weak" and setting the air volume of the air conditioning unit 130 to "medium."

[0074] This allows the air in each room of the house 1 to be appropriately humidified. Specifically, when the air conditioner 120 determines that the set temperature has been reached during automatic operation, the thermo-off function of the air conditioner 120 is activated and the airflow rate is set to "weak." Accordingly, the airflow rate of the air conditioning unit 130 (blower fan) is also set to "weak." This causes the air to stop circulating (or becomes difficult to circulate), preventing humidified air from being transported to each room, and making it impossible to sufficiently humidify each room. Furthermore, if the humidity becomes high only in the auxiliary room 30, the operation of the humidifier 110 will stop, making it even more difficult to sufficiently humidify each room.

[0075] Therefore, in air conditioning system 100, when the room temperature in each room stabilizes and air conditioner 120 is turned off, the operating mode of air conditioner 120 and air conditioning unit 130 is set to the fan mode, and the air volume of air conditioning unit 130 is forcibly switched from "weak" to "medium," thereby delivering humidified air to each room. This makes it possible to humidify the air in each room and bring the humidity in each room closer to the target humidity.

[0076] On the other hand, in step S13, if the control unit 200 determines that "the room temperature of each room in the house 1 has not reached the set temperature and 30 minutes have not passed since reaching that temperature" ("NO" in step S13), the control unit 200 temporarily ends the airflow mode switching flow and proceeds to step S3 of the control flow shown in Fig. 7. Also, in step S14, if the control unit 200 determines that the airflow rates of the air conditioner 120 and the air conditioning unit 130 are not "weak" (i.e., are "medium" or "strong") ("NO" in step S14), the control unit 200 also temporarily ends the airflow mode switching flow and proceeds to step S3 of the control flow shown in Fig. 7.

[0077] Note that "NO" in step S13 indicates that the room temperature of each room has not yet reached the set temperature (has not yet stabilized near the set temperature). Also, "NO" in step S14 indicates that the air conditioner 120 and the air conditioning unit 130 are not in thermo-off mode (operating) in automatic operation.

[0078] Therefore, in this case, the operation modes of the air conditioner 120 and the air conditioning unit 130 are not switched to the fan mode, and the air conditioner 120 and the air conditioning unit 130 continue to operate automatically.

[0079] Next, the normal mode switching flow (step S3 in FIG. 7) will be described in detail using the flowchart in FIG.

[0080] In step S21, the control unit 200 checks the status of the air conditioner 120 and the air conditioning unit 130 (blower fan). Specifically, the control unit 200 acquires current information (operation / stop, set temperature, air volume, etc.) of the air conditioner 120 and the air conditioning unit 130. After performing the process of step S21, the control unit 40 proceeds to step S22.

[0081] In step S22, the control unit 200 acquires the air temperature (room temperature) in each room of the house 1. Specifically, the control unit 200 acquires the measurement results of the temperature sensors 180 provided in each room. After performing the process of step S22, the control unit 40 proceeds to step S23.

[0082] In step S23, the control unit 200 determines whether the set temperature -1°C is greater than or equal to the room temperature. That is, the control unit 200 determines whether the room temperature of each room has dropped by 1°C or more from the set temperature (whether the room is getting colder than the set temperature). The control unit 200 determines "YES" if all rooms provided with air outlets 170 satisfy the above condition.

[0083] If the control unit 200 determines that the set temperature -1°C is greater than or equal to room temperature ("YES" in step S23), the control unit 200 proceeds to step S24. On the other hand, if the control unit 200 determines that the set temperature -1°C is not greater than or equal to room temperature (set temperature -1°C<room temperature) ("NO" in step S23), the control unit 200 temporarily ends the normal mode switching flow and also temporarily ends the control flow shown in FIG. 7.

[0084] Note that "YES" in step S23 indicates that the room temperature in each room has dropped significantly below the set temperature (for example, to the extent that people in the room notice the drop in room temperature). On the other hand, "NO" in step S23 indicates that the room temperature in each room has not yet dropped significantly below the set temperature. Here, the value "1" in "set temperature -1°C" is a threshold value that indicates the degree of drop in the room temperature in each room relative to the set temperature, and is not limited to this, and may be another value.

[0085] In step S24, the control unit 200 determines whether the operation mode of the air conditioner 120 and the air conditioning unit 130 is the fan mode.

[0086] When the control unit 200 determines that the operation mode of the air conditioner 120 and the air conditioning unit 130 is the fan mode ("YES" in step S24), the process proceeds to step S25.

[0087] In step S25, the control unit 200 switches the operation mode of the air conditioner 120 and the air conditioning unit 130 to the normal mode, whereby the air conditioner 120 and the air conditioning unit 130 perform automatic operation.

[0088] In this way, when the temperature in each room drops below the set temperature (becomes cold), the air conditioner 120 and the air conditioning unit 130 can be returned to automatic operation, allowing the room temperature in each room to approach the set temperature.

[0089] As described above, in the air conditioning system 100 according to this embodiment, the humidifying capacity can be improved by optimizing the air flow (by having the air flow through the humidifier 110, air conditioner 120, and air conditioning unit 130 in that order). Furthermore, when the air conditioner 120 is thermo-off, the operating modes of the air conditioner 120 and air conditioning unit 130 are set to the fan mode, and the air volume of the air conditioning unit 130 is forcibly switched from "weak" to "medium," thereby transporting humidified air to each room and further improving the humidifying capacity.

[0090] In addition, conventionally, a water-connected humidifier was installed in the circulation path of the air conditioner to humidify the heated air before transporting it to each room. This method posed a high risk of sanitation management issues, such as scale and water leakage, and required maintenance by a specialized contractor. Another issue was that the humidifying capacity was insufficient, making it difficult to precisely control humidity.

[0091] In contrast, in the air conditioning system 100 according to this embodiment, the humidifier 110 is provided in a space separate from the air conditioner 120 and the air conditioning unit 130, thereby improving ease of maintenance. Furthermore, since an appropriate humidifier (e.g., a commercially available product) can be used as the humidifier 110, it is possible to further improve ease of maintenance and improve the accuracy of humidification capacity and humidity control. Furthermore, other functions, such as a deodorizing function or aromatherapy, can be added.

[0092] As described above, the air conditioning system 100 according to this embodiment has the following features: a humidifier 110 provided in the auxiliary chamber 30 (first chamber) and capable of humidifying the air in the auxiliary chamber 30; an air conditioner 120 that is provided in a machine room 20 (second room) that allows air to flow between the machine room 20 and the auxiliary room 30, sucks in air from the machine room 20, adjusts the temperature, and discharges the temperature-adjusted air; an air conditioning unit 130 (transport device) provided in the machine room 20, which transports the air discharged from the air conditioner 120 to each room in the house 1 (building); It is equipped with the following.

[0093] This configuration makes it possible to improve maintenance ease and humidifying capacity. Specifically, by installing the air conditioner 120 and the air conditioning unit 130 in the machine room 20 and installing the humidifier 110 in the auxiliary room 30 which allows air communication between the machine room 20, it becomes easier to make the air flow appropriate, and ultimately the humidifying capacity can be improved. Furthermore, by providing the humidifier 110 in a space separate from the air conditioner 120 and the air conditioning unit 130, maintenance can be made easier.

[0094] The air conditioner 120 is provided above the air conditioning unit 130, The ancillary room 30 and the machinery room 20 communicate with each other above the air conditioner 120 (by means of a wall grille 160) to allow air to circulate.

[0095] With this configuration, the humidifying capacity can be further improved. Specifically, air humidified by humidifier 110 can be sent to air conditioning unit 130 via air conditioner 120 through wall grille 160. That is, it is possible to prevent air humidified by humidifier 110 from being sent directly to air conditioning unit 130 without going through air conditioner 120. This makes it possible to prevent air that has been temperature-controlled but not humidified, or air that has been humidified but not temperature-controlled, from being sent to each room.

[0096] The auxiliary room 30 and the machine room 20 are arranged adjacent to each other.

[0097] With this configuration, the ancillary chamber 30 and the machine chamber 20 can be easily connected to each other. Specifically, the ancillary room 30 and the machinery room 20 can be communicated with each other simply by opening the wall between them (without the need for a duct).

[0098] Moreover, the air conditioning system 100 according to this embodiment has: a temperature sensor 180 for measuring the room temperature of each room; a control unit (200) for controlling the operation of the air conditioner (120) and the air conditioning unit (130); Equipped with The control unit 200 a normal mode (normal operation) in which the air conditioner 120 and the air conditioning unit 130 are operated until it is determined that the room temperature measured by the temperature sensor 180 has reached a set temperature, and the air conditioner 120 and the air conditioning unit 130 are stopped when it is determined that the room temperature has reached the set temperature; a fan mode (fan operation) in which the air conditioning unit 130 is operated even after it is determined that the room temperature has reached the set temperature; It is possible to carry out the above.

[0099] With this configuration, it is possible to prevent each room in the house 1 from becoming unhumidified. Specifically, even if the room temperature in each room reaches the set temperature and the air conditioner 120 stops, by continuing to operate the air conditioning unit 130, it is possible to prevent the humidity from becoming high only in the auxiliary room 30, which would cause the humidifier 110 to stop. Then, since the humidified air can be transported to each room, each room can be humidified.

[0100] In addition, the control unit 200 After the fan mode (fan operation) is executed, if it is determined that the room temperature and the set temperature have deviated by a predetermined value or more, the mode is switched to the normal mode (normal operation).

[0101] With this configuration, the temperature of each room in the house 1 can be brought close to the set temperature. Specifically, if the room temperature in each room drops too low compared to the set temperature, the mode is switched to normal and the air conditioner 120 is operated automatically, thereby bringing the temperature in each room closer to the set temperature.

[0102] The house 1 according to this embodiment is one embodiment of a building according to the present invention. The auxiliary chamber 30 according to this embodiment is one embodiment of the first chamber according to the present invention. The machine chamber 20 according to this embodiment is an embodiment of the second chamber according to the present invention. The air conditioning unit 130 according to this embodiment is one embodiment of a transport device according to the present invention.

[0103] Although the embodiment of the present invention has been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention described in the claims.

[0104] For example, in this embodiment, in step S13 of FIG. 8 and step S23 of FIG. 9, the control unit 200 judges "YES" if all rooms in which the air outlets 170 are installed satisfy the judgment conditions of the step, but it may also judge "YES" if a predetermined number of rooms satisfy the above conditions, or it may judge the room temperature of each room comprehensively (for example, using an average value, etc.).

[0105] In addition, in this embodiment, the auxiliary room 30 is located adjacent to the machine room 20, but as long as air can flow between the auxiliary room 30 and the machine room 20, it does not necessarily have to be adjacent and may be located at a distance.

[0106] Furthermore, the house 1 illustrated in this embodiment is just one example, and the present invention can be applied to various other buildings (businesses such as commercial facilities and factories, public facilities such as government offices, etc.). Furthermore, the floor plan of the building (house 1) illustrated in this embodiment is just one example, and the present invention can be applied to buildings with various floor plans. Furthermore, in this embodiment, the master bedroom 2 and the like are targeted for air conditioning control, but the present invention is not limited to this, and various rooms, whether occupied or unoccupied, can be targeted for air conditioning control.
