The air conditioning control adjustment device disclosed in Patent Document 1 requires a user to prepare a mobile terminal. Therefore, it is necessary to report a request regarding the air-conditioning environment in the area to the air-conditioning control and adjustment device. In addition, since the details of air conditioning control for an area are determined based on the awareness (thoughts) of users with different attributes (age, gender, position differences in workplaces, etc.), the awareness (thoughts) of each user diverges. In this case, the contents of the air conditioning control in the area may become unsuitable for each user.

In the chair disclosed in Patent Document 2, air is blown from the air blower toward the user (task area) seated on the chair, but it is not interlocked with the ambient area air conditioning in the room where the chair is installed. The temperature of the air-conditioned air in the room cannot be changed according to the usage of each chair, and optimal task/ambient air-conditioning cannot be performed for the user of the chair.

An object of the present invention is to eliminate the need for each user in the room to consciously change the setting of the ambient area air conditioning, save the trouble of each user, and prevent each user from feeling burdened. To provide a task/ambient air-conditioning system capable of supplying optimal conditioned air for each user to a room regardless of the consciousness (idea) of each user. Another object of the present invention is to be able to change the temperature of the conditioned air supplied to the room of the building in which the chair is installed, which is equipped with a blower and a heating device, according to the usage of each chair. To provide a task/ambient air-conditioning system capable of carrying out optimal task/ambient air-conditioning for a user of a chair installed.

The premise of the present invention for solving the above problems is an air conditioner that supplies conditioned air of a predetermined temperature to a room, and one or more chairs that are installed in the room and on which the user sits. operates in either a blowing mode for blowing a predetermined amount of air toward the user seated on it or a heating mode for warming at least the buttocks, waist, and back of the user seated on it. The task/ambient air conditioning system has an ON state and an OFF state in which neither the air blowing mode nor the heating mode is operated, and air-conditions an indoor task area using an air conditioner.

The feature of the present invention based on the above premise is that the task/ambient air-conditioning system determines which chairs are in the ON state and determines whether the proportion of chairs in the ON state is equal to or greater than the effective proportion ; The operation state determination means detects that the chairs in the ON state are in either the fan mode or the heating mode, and the operation state determination means determines that the ratio of the chairs in the ON state is equal to or greater than the effective ratio. ambient air conditioning control change calculation means for determining whether the average output value obtained by averaging the output value of the chair operating in the fan mode or the output value of the chair operating in the heating mode is equal to or greater than the set output value. In the task/ambient air-conditioning system, when the operating state determination means determines that the proportion of chairs in the ON state is less than the effective proportion, or when the ambient air-conditioning control change calculation means determines that the average output value is less than the set output value If it is determined that the air conditioner is operated in a normal mode in which the set temperature of the air conditioner is maintained at a preset set temperature, and the proportion of chairs that are in the ON state by the operating state determination means is equal to or greater than the effective proportion. When it is determined that the ambient air conditioning control change calculation means determines that the average output value is equal to or greater than the set output value, the set temperature of the air conditioner is increased or decreased from the set temperature of the air conditioner operated in the normal mode. mode to operate the air conditioner .

As an example of the present invention, the task-ambient air-conditioning system implements the operating state determination means and the ambient air-conditioning control change calculation means, and switches the operation of the air conditioner between the normal mode and the boost mode via a predetermined network. An identifier that can identify a chair is assigned to each chair, and the ambient area air conditioning control change means identifies the chairs by the identifier, and the chair is directed toward the user seated on it. A blower for blowing a predetermined amount of air, a heating device for warming at least the buttocks of a user sitting on it, a seating sensor for detecting whether the user is seated or not, and a blower for a chair. and switching means for switching ON/OFF of the heating device and switching between the blowing mode and the heating mode of the chair, output adjusting means for adjusting the output of the blowing device of the chair and the output of the heating device, the identifier of the chair, and the seating sensor. communication means for transmitting the detected seating state value, the ON/OFF state value of the blower and the heating device, the output value of the blower or the output value of the heating device to the ambient area air conditioning control changing means via the network.

As another example of the present invention, in the operation of the air conditioner in the boost mode during the cooling period, the set temperature of the air conditioner is lowered below the set temperature of the air conditioner that operates in the normal mode, and the temperature of the air conditioner during the heating period is reduced. In boost mode operation, the set temperature of the air conditioner is raised above the set temperature of the air conditioner that operates in the normal mode.

As another example of the present invention, in the driving state determination means, the number of chairs on which the user is seated is used as the denominator, and the number of chairs in the ON state among the chairs on which the user is seated is used as the numerator. is calculated, and it is determined whether the calculated ratio of chairs in the ON state is equal to or greater than the effective ratio.

As another example of the present invention, in the task/ambient air conditioning system, the effective ratio of chairs in the ON state determined by the operating state determination means is set in the range of 70% to 90%, and the ambient air conditioning control change calculation means The set output value of the determined average output value is set in the range of 50% to 70% of the maximum average output value.

As another example of the present invention, the ambient area air conditioning control change means uses an identifier assigned to each chair to group a predetermined number of chairs into a first chair group to an nth chair group, The operating state determination means and the ambient air conditioning control change calculation means are implemented for each group of the first chair group to the n-th chair group, and the conditioned air of a predetermined temperature is supplied from the air conditioner operating in the normal mode or the boost mode to the first chair group. Air is supplied to each of the n-th chair groups.

According to the task ambient air conditioning system according to the present invention, for example, there are many users of chairs in the room, the frequency of use of the fan mode or heating mode in the chair is high, and the set temperature of the air conditioner is set in advance. If each user feels uncomfortable with the air-conditioned environment in the room, the set temperature of the air conditioner is set to the normal mode by the operating state determination means and the ambient air conditioning control change calculation means. Since the air conditioner is operated in a boost mode that raises or lowers the temperature, it is possible to supply conditioned air at an optimum temperature to the user of the chair in the room. It is possible to achieve optimal task/ambient air conditioning that is well-balanced with comfort. The task/ambient air-conditioning system supplies air to the room with the optimal conditioned air for each user, regardless of the awareness (thoughts) of each user with different attributes (age, gender, job title in the case of a workplace, etc.). This eliminates the need for each user to consciously perform a predetermined operation, thereby saving time and effort for each user and eliminating the burden on each user.

The operating state determining means determines whether the proportion of chairs in the ON state is equal to or greater than the effective proportion, and the ambient air conditioning control change calculating means determines by the operating state determining means that the proportion of chairs in the ON state is equal to or greater than the effective proportion. In this case, it is determined whether the average output value obtained by averaging the output value of the chair operating in the fan mode or the output value of the chair operating in the heating mode is equal to or greater than the set output value, and the operation state determination means turns ON. If it is determined that the ratio of chairs in the state is less than the effective ratio, or if it is determined by the ambient air conditioning control change calculation means that the average output value is less than the set output value, the set temperature of the air conditioner is set in advance. The air conditioner is operated in a normal mode in which the temperature is maintained at the set temperature, and the operating state determination means determines that the proportion of chairs in the ON state is equal to or greater than the effective proportion, and the ambient air conditioning control change calculation means sets the average output value. If it is determined that the output value or more, the task ambient air conditioning system that operates the air conditioner in a boost mode that raises or lowers the set temperature of the air conditioner to be higher or lower than the set temperature of the air conditioner that operates in the normal mode is in the ON state. If the proportion of chairs in the room is less than the effective proportion, there are few users of chairs in the room, and even if the set temperature of the air conditioner is maintained at the preset temperature, each user will not feel uncomfortable. and operating the air conditioner in a normal mode in which the set temperature of the air conditioner is maintained at a preset temperature when it is determined by the operating state determination means that the proportion of chairs in the ON state is less than the effective proportion, A task-ambient air conditioning suitable for the user of the chair in the room can be implemented. If the average output value obtained by averaging the output value of the chair operating in the fan mode or the output value of the chair operating in the heating mode is less than the set output value, the task/ambient air conditioning system switches to the fan mode in the chair or Even if the frequency of use of the heating mode is low and the set temperature of the air conditioner is maintained at the preset set temperature, each user does not feel uncomfortable. If it is determined to be less than the preset temperature, the air conditioner is operated in a normal mode that maintains the set temperature of the air conditioner at the preset temperature, thereby implementing task/ambient air conditioning suitable for the user of the chair in the room. be able to. In the task/ambient air conditioning system, the ratio of chairs in the ON state is equal to or higher than the effective ratio, and the output value of chairs operating in the fan mode or the output value of the chairs operating in the heating mode is averaged. When the output value is equal to or higher than the set output value, there are many people using chairs in the room, and the frequency of using the fan mode or heating mode in the chair is high, and the set temperature of the air conditioner is maintained at the set temperature set in advance. Each user may feel uncomfortable with the air-conditioned environment in the room, but the operating state determination means determines that the ratio of chairs in the ON state is equal to or greater than the effective ratio, and the ambient air-conditioning control change calculation means average output When it is determined that the value is equal to or higher than the set output value, the air conditioner is operated in a boost mode in which the set temperature of the air conditioner is raised or lowered to be higher or lower than the set temperature of the air conditioner operated in the normal mode. It is possible to supply conditioned air at the optimum temperature to the user, realizing optimal task/ambient air conditioning corresponding to the frequency of use of the chair, the frequency of use of the fan mode or heating mode, and the output value of the fan mode or heating mode. can do. The task ambient air conditioning system automatically switches the operation mode of the air conditioner to normal mode or boost mode regardless of the consciousness (thoughts) of each user, so each use can be performed regardless of the consciousness (thoughts) of each user. To supply conditioned air optimum for a user to a room, eliminate the need for each user to consciously perform a predetermined operation, save the trouble of each user, and eliminate the burden on each user. be able to.

In the chair ventilation mode, the task ambient air conditioning system blows a predetermined amount of air from the blower installed in the chair toward the user, and by blowing indoor conditioned air on the user, the user's body temperature and The sensible temperature can be lowered, and at least the buttocks of the user's buttocks and waist can be warmed by the heating device installed in the chair when the chair is in the heating mode, and the conditioned air supplied from the air conditioner can be used. Concomitantly, the user's body temperature and sensible temperature can be optimally adjusted. In the task/ambient air conditioning system, an identifier that can identify each chair is assigned to each chair, and the ambient area air conditioning control change means identifies each chair by the identifier, so the seating state value of the chair (seated or not seated on the chair) , the ON/OFF state values of the blower and the heating device (on/off of the blower and the heating device), the output value of the air blowing mode of the chair or the output value of the heating mode for each chair, and the ON state It is possible to accurately determine whether the ratio of chairs in the state is equal to or higher than the effective ratio, and the average of the output values of chairs operating in fan mode or the output value of chairs operating in heating mode It is possible to accurately determine whether the output value is greater than or equal to the set output value. Since the task/ambient air-conditioning system can accurately execute the operating state determination means and the ambient air-conditioning control change calculation means while specifying the chair by the identifier, the conditioned air at the optimum temperature for the user of the chair in the room can be provided. Air can be supplied, and optimum task/ambient air conditioning corresponding to the frequency of use of the chair, the frequency of use of the fan mode or heating mode, and the output value of the fan mode or heating mode can be realized.

In the driving state determination means, the ratio of chairs in the ON state is calculated using the number of chairs in which the user sits as the denominator and the number of chairs in the ON state among the chairs in which the user sits as the numerator. A task-ambient air conditioning system that determines whether the ratio of chairs in the ON state is equal to or greater than the effective ratio, determines whether the ratio of chairs in the ON state to the chair on which the user is seated is less than the effective ratio. Even if the frequency of use of the fan mode or the heating mode is low and the set temperature of the air conditioner is maintained at the preset set temperature, each user will not feel uncomfortable. When it is determined that the ratio of chairs in the ON state to the chairs on which the chair is seated is less than the set ratio, the air conditioner is operated in the normal mode in which the set temperature of the air conditioner is maintained at the preset temperature. It is possible to implement task-ambient air conditioning suitable for chair users in In the task/ambient air conditioning system, the ratio of chairs in the ON state to the chairs on which the user is seated is equal to or higher than the effective ratio, and the output value of the chairs operating in the ventilation mode or the number of chairs operating in the heating mode If the average output value obtained by averaging the output values is equal to or higher than the set output value, there are many people using chairs in the room, and the frequency of using the ventilation mode or heating mode in the chair is high, and the set temperature of the air conditioner is set in advance. When the set temperature is maintained at the set temperature, each user may feel uncomfortable with the air-conditioned environment in the room, but the ratio of chairs in the ON state to the chairs on which the user is seated by the operating state determination means is equal to or higher than the effective ratio. When it is determined that the ambient air conditioning control change calculation means determines that the average output value is equal to or greater than the set output value, the set temperature of the air conditioner is increased or decreased from the set temperature of the air conditioner operated in the normal mode. Since the air conditioner is operated in the mode, it is possible to supply conditioned air at an optimum temperature to the user of the chair in the room, and the frequency of use of the chair, the frequency of use of the fan mode or the heating mode, It is possible to realize optimal task/ambient air conditioning corresponding to the output value of

In this indoor air conditioning, as shown in FIG. 4, conditioned air is blown out from the indoor unit 24 on the ceiling 41 toward the user Y (the chair 14) to cool and heat the surroundings of the user Y (task area 42). The task area 42 can be kept comfortable, and the user Y can work comfortably while saving energy for air conditioning in the ambient area 43 .

FIG. 5 is a flow chart showing an example of each means performed in the task/ambient air-conditioning system 10 .

An example procedure for using the task-ambient air conditioning system 10 is as follows. To activate the task ambient air conditioning system 10, tap (click) a system ON button (not shown). When the system ON button is tapped, the wireless LAN router 12 is connected to the Internet, and the wireless LAN router 12 accesses and logs into the ambient area air conditioning control change means 11 . When the task/ambient air-conditioning system 10 is activated, the user Y is not seated on any of the chairs 14 . It is assumed that the ON/OFF switch (switching means) of the chair 14 is OFF.

In the task-ambient air-conditioning system 10, the effective ratio (set ratio) of the chairs 14 in the ON state and the set output value of the chairs operating in the fan mode or the heating mode are set in advance. The set effective ratio and the set output value are temporarily stored (stored) in the cache memory of the ambient area air conditioning control changing means 11 . A cooling period and a heating period can also be set. Also, the set temperature of the room 16 is set by the air conditioner remote controller 17 .

The valid ratio (driving mode switching determination value) is a ratio that serves as a threshold (boundary value) for the ratio of chairs in the ON state in the operating state determination means performed by the ambient area air conditioning control change means 11 . The operating state determination means determines whether the chair 14 is in the fan mode (when the fan mode ON signal is received during the cooling period) or the heating mode (when the heating mode ON signal is received during the heating period). When the vehicle is driven with the chair 14, it is determined that the chair 14 is in the ON state. It is assumed that the effective ratio of chairs 14 in the ON state is set at 90%. The effective ratio of chairs 14 in the ON state can be set within the range of 70% to 90%.

In the operation state determination means of the ambient area air conditioning control change means 11, the number of chairs 14 on which the user Y is seated (chairs transmitting a seating signal (seating sensor ON)) is used as the denominator, and the number of chairs 14 on which the user Y is seated is The ratio of chairs 14 in the ON state is calculated using the number of chairs 14 in the ON state (chairs 14 transmitting the blowing mode OFF signal or the heating mode OFF signal) among the 14 as the numerator. It is determined whether the ratio of a certain chair 14 is equal to or higher than a preset valid ratio (for example, 90% or higher) or less than the valid ratio (for example, less than 90%). In this case, when the user Y is seated on the chair 14 (although the seating signal (seating sensor ON) is received), neither the ventilation mode nor the heating mode is operated (the ventilation mode OFF signal or when a heating mode OFF signal is received), it is determined that the chair 14 is in the OFF state.

Further, when the chair 14 on which the user Y is seated is operated in the air blowing mode during the heating period (winter) (when the air blowing mode ON signal is received during the heating period), the chair 14 is in the OFF state. The chair 14 is not included in the denominator of the ratio calculation.

The set output value (operation mode switching determination value) is the output value of the chair 14 operating in the fan mode or the chair operating in the heating mode in the ambient air conditioning control change calculation means executed by the ambient area air conditioning control change means 11. This output value is the threshold value (boundary value) of the average output value obtained by averaging the 14 output values. The set output value of the average output value determined by the ambient air conditioning control change calculation means is set at 60% of the maximum average output value (for example, the output value of the blower 30 or the heating device 31 is five levels from weak to strong (for example , Weak 2, Weak 1, Medium, Strong 1, and Strong 2) are set to 3 levels (medium)). The set output value can be set within a range of 50 to 70% of the maximum average output value. In the ambient air conditioning control change calculation means, the average output value obtained by averaging the output value of the chair 14 operating in the fan mode or the output value of the chair 14 operating in the heating mode is equal to or greater than the set output value, or Determine if it is less than the output value.

When the ambient air conditioning control change calculation means determines that the average output value is equal to or greater than the set output value (C≧set output value), the ambient area air conditioning control change means 11 changes the set temperature of the air conditioner 13 (air conditioner 13 (S-5).

The ambient area air conditioning control changing means 11 transmits a boost mode signal (control command) to the control section of the air conditioner 13 . Upon receiving the boost mode signal, the controller of the air conditioner 13 switches the air conditioner 13 from the normal mode to the boost mode, and operates the air conditioner 13 in the boost mode. In the boost mode, the set temperature of the air conditioner 13 (the temperature of the conditioned air supplied from the air conditioner 13) is lowered by 1 to 2° C. from the preset set temperature during the cooling period, and the air conditioner 13 is set during the heating period. (the temperature of the conditioned air supplied from the air conditioner 13) is raised by 1 to 2° C. from the preset temperature.

In step 3 (S-3), when the task ambient air-conditioning system 10 is terminated while the boost mode operation is continued, the ambient zone air-conditioning control changing means 11 is stopped.
