FIG. 1 shows a conceptual diagram of anenvironmental control system 1 according to a first embodiment of the present invention. In addition,FIG. 2 shows a block diagram of the constituent elements of theenvironmental control system 1 according to the first embodiment of the present invention. Theenvironmental control system 1 shown inFIG. 1 is principally for controlling an air conditioned environment of a room RM. - The
environmental control system 1 shown inFIG. 1 principally comprises anenvironmental control apparatus 10 and anair conditioner 20. Theenvironmental control apparatus 10 is installed in the room RM and is portable. The external form of theenvironmental control apparatus 10 takes the form of, for example, Pichon-kun™. Theair conditioner 20 principally conditions the air environment of the room RM (refer toFIG. 1 ). - As shown in
FIG. 2 , theenvironmental control apparatus 10 shown inFIG. 1 principally comprises asensor unit 11, adetermination unit 12, ageneration unit 13, asend unit 14, and astorage unit 15. Thestorage unit 15 principally storescomfort zone information 18 and controlinformation 19. - The
sensor unit 11 shown inFIG. 2 senses the air environment of the room RM. Thedetermination unit 12 receives information about the air environment of the room RM from thesensor unit 11. Thedetermination unit 12 references thestorage unit 15 and acquires thecomfort zone information 18. Thedetermination unit 12 determines whether the air environment of the room RM is within a range of a comfort zone based on the information about the air environment of the room RM and thecomfort zone information 18. Thegeneration unit 13 receives both information about the determination result of thedetermination unit 12 and information about the air environment of the room RM from thedetermination unit 12. Here, information about the determination result of thedetermination unit 12 is information on whether the air environment of the room RM is within the range of the comfort zone. Thegeneration unit 13 references thestorage unit 15 and acquires thecontrol information 19. Based on the information about the determination result of thedetermination unit 12 and the information about the air environment of the room RM, thegeneration unit 13 generates a control signal so that the air environment of the room RM falls within the range of the comfort zone. Thesend unit 14 receives control signal information from thegeneration unit 13. Based on the information about the determination result of thedetermination unit 12, thesend unit 14 sends the control signal to theair conditioner 20 via a wireless circuit. - As shown in
FIG. 2 , theair conditioner 20 shown inFIG. 1 principally comprises areception unit 21 and anenvironment providing unit 22. - The
reception unit 21 shown inFIG. 2 receives the control signal from theenvironmental control apparatus 10 via the wireless circuit. Theenvironment providing unit 22 receives the control signal from thereception unit 21. Theenvironment providing unit 22 provides the air conditioned environment to the room RM based on the control signal. - The
comfort zone information 18 shown inFIG. 2 indicates various cases in which the air environment of the room RM is within the range of the comfort zone. Thecomfort zone information 18 is, for example, the information shown inFIG. 4 . As shown inFIG. 4 , thecomfort zone information 18 principally comprises anenvironment field 181, alower limit field 182, and anupper limit field 183. Referencing thecomfort zone information 18 shown inFIG. 4 , it can be seen that, for example, the temperature comfort zone is 20°-26° C. Alternatively, it can be seen that, for example, the humidity comfort zone is 40%-70%. Alternatively, it can be seen that, for example, the comfort zone of the dew point temperature differential is greater than or equal to 4° C. Here, the dew point temperature differential is derived by the equation below. -
Dew point temperature differential=(Room temperature)−(Dew point temperature) (1) - Alternatively, it can be seen that, for example, the dust concentration comfort zone is 0.10 mg/m3 or less.
- The
control information 19 shown inFIG. 2 constitutes the candidates for the contents of the control signal that is generated by thegeneration unit 13. Thecontrol information 19 is, for example, the information shown inFIG. 5 . As shown inFIG. 5 , thecontrol information 19 principally comprises anenvironment field 191, alower limit field 192, anupper limit field 193, and a control detailsfield 194. Referencing thecontrol information 19 shown inFIG. 5 , it can be seen that, for example, a control signal to perform “automatic operation with the temperature set to 24° C.” should be generated when the temperature is greater than or equal to 27° C. Alternatively, it can be seen that, for example, a control signal to perform “automatic operation with the temperature set to 24° C.” should be generated when the temperature is 19° C. or less. Alternatively, it can be seen that, for example, a control signal to perform “dehumidifying operation with the airflow set to ‘low’” should be generated when the dew point temperature differential is greater than or equal to 4° C. Alternatively, it can be seen that, for example, a control signal to perform “dehumidifying operation with the airflow set to ‘high’” should be generated when the dew point temperature differential is 0°-4° C. Alternatively, it can be seen that, for example, a control signal to perform “ventilation operation with ‘high’ airflow ” should be generated when the dew point temperature differential is 0° C. or less. Alternatively, it can be seen that, for example, a control signal to perform “air purification operation with ‘high’ airflow” should be generated when the dust concentration is greater than or equal to 0.15 mg/m3. Alternatively, it can be seen that, for example, a control signal to perform “air purification operation with ‘low’ airflow” should be generated when the dust concentration is 0.10-0.15 mg/m3. - The flow of the process wherein the
environmental control system 1 shown inFIG. 1 controls the air environment of the room RM will now be explained using the flow chart shown inFIG. 3 . - In step S1 shown in
FIG. 3 , the air environment of the room RM shown inFIG. 1 is sensed. Namely, thesensor unit 11 shown inFIG. 2 senses the air environment of the room RM. - In step S2 shown in
FIG. 3 , it is determined whether the air environment of the room RM shown inFIG. 1 is within the range of the comfort zone. Namely, thedetermination unit 12 of theenvironmental control apparatus 10 shown inFIG. 2 receives information about the air environment of the room RM from thesensor unit 11. Thedetermination unit 12 references thestorage unit 15 and acquires thecomfort zone information 18. Thedetermination unit 12 determines whether the air environment of the room RM is within the range of the comfort zone based on the information about the air environment of the room RM and thecomfort zone information 18. If the air environment of the room RM is determined to be within the range of the comfort zone, then the process proceeds to step S1; in addition, if it is determined that it is not within the range of the comfort zone, then the process proceeds to step S3. - In step S3 shown in
FIG. 3 , the control signal is generated. Namely, thegeneration unit 13 of theenvironmental control apparatus 10 shown inFIG. 2 receives both information about the determination result of thedetermination unit 12 and information about the air environment of the room RM from thedetermination unit 12. Here, information about the determination result of thedetermination unit 12 is information on whether the air environment of the room RM is within the range of the comfort zone. Thegeneration unit 13 references thestorage unit 15 and acquires thecontrol information 19. Based on the information about the determination result of thedetermination unit 12 as well as the information about the air environment of the room RM, thegeneration unit 13 generates a control signal so that the air environment of the room RM falls within the range of the comfort zone. - In step S4 shown in
FIG. 3 , the control signal is sent. Namely, thesend unit 14 of theenvironmental control apparatus 10 shown inFIG. 2 receives the control signal information from thegeneration unit 13. Based on the information about the determination result of thedetermination unit 12, thesend unit 14 sends the control signal to theair conditioner 20 via the wireless circuit. Thereception unit 21 of theair conditioner 20 shown inFIG. 2 receives the control signal from theenvironmental control apparatus 10 via the wireless circuit. Theenvironment providing unit 22 receives the control signal from thereception unit 21. - In step S5 shown in
FIG. 3 , an air conditioned environment is provided. Namely, theenvironment providing unit 22 of theair conditioner 20 shown inFIG. 2 provides the air conditioned environment to the room RM based on the control signal. - (1)
- Here, the
sensor unit 11 shown inFIG. 2 senses the air environment of the room RM. Thedetermination unit 12 receives information about the air environment of the room RM from thesensor unit 11. Thedetermination unit 12 determines whether the air environment of the room RM is within the range of the comfort zone based on the information about the air environment of the room RM and thecomfort zone information 18. Thegeneration unit 13 receives information about the determination result of thedetermination unit 12 and information about the air environment of the room RM from thedetermination unit 12. Based on the information about the determination result of thedetermination unit 12 and the information about the air environment of the room RM, thegeneration unit 13 generates the control signal so that the air environment of the room RM falls within the range of the comfort zone. Thesend unit 14 receives the control signal information from thegeneration unit 13. Based on the information about the determination result of thedetermination unit 12, thesend unit 14 sends the control signal via the wireless circuit so that the air environment of the room RM falls within the range of the comfort zone. Thereby, theair conditioner 20 receives the control signal via the wireless circuit so that the air environment of the room RM falls within the range of the comfort zone. - Accordingly, the control signal is sent to the
air conditioner 20 so that the air environment of the room RM falls within-the range of the comfort zone, and it is therefore possible to control theair conditioner 20 so that the air environment of the room RM falls within the range of the comfort zone without making the user (not shown) aware of the comfort zone. Consequently, the air environment of the room RM can be made automatically comfortable without making the user aware of such. - (2)
- Here, the air environmental factors of the room RM shown in
FIG. 1 are the temperature, the dew point temperature differential, the humidity, and the dust concentration of the room RM (refer toFIG. 4 ). - Accordingly, it is possible to finely determine whether the air environment of the room RM shown in
FIG. 1 is within the range of the comfort zone, which makes it possible to finely control theair conditioner 20 so that the air environment of the room RM falls within the range of the comfort zone. - (A) The air environmental factor of the room RM shown in
FIG. 1 may be at least one of the temperature, the dew point temperature differential, the humidity, the atmospheric pressure, the airflow, the toxic substance concentration, the dust concentration, and the negative ion concentration of the room RM. Here, toxic substances may be at least one of, for example, carbon monoxide, carbon dioxide, allergens, mites, mold, formaldehyde, organic compounds, VOCs (volatile organic compounds) and endocrine disrupters. Thesensor unit 11 shown inFIG. 2 may sense the dew point temperature differential of the room RM by measuring the temperature, the humidity, and the atmospheric pressure of the room RM, deriving the dew point temperature of the room RM therefrom, and then deriving the dew point temperature differential of the room RM. In addition, thesensor unit 11 shown inFIG. 2 may sense the temperature, the humidity, and the atmospheric pressure of the room RM, and thedetermination unit 12 may then predict the weather based on that information and thereby determine whether the air environment of the room RM is within the range of the comfort zone while taking that weather prediction into consideration. In addition, thegeneration unit 13 may also generate the control signal while taking the weather prediction into consideration. In this case, it is possible to more finely determine whether the air environment of the room RM shown inFIG. 1 is within the range of the comfort zone, and to more finely control theair conditioner 20 so that the air environment of the room RM is within the range of the comfort zone. - The information about the air environment of the room RM, which was sensed by the
sensor unit 11, may be accumulated in thestorage unit 15. Furthermore, the information about the air environment of the room RM, which is stored in thestorage unit 15, may be analyzed. Thereby, it is possible to predict changes in the air environment of the room RM and to control theair conditioner 20 so that the air environment of the room RM falls within the range of the comfort zone. - Based on only the information about the determination result of the
determination unit 12, thegeneration unit 13 shown inFIG. 2 may generate the control signal so that the air environment of the room RM falls within the range of the comfort zone. In this case, thelower limit field 192 and theupper limit field 193 shown inFIG. 5 may be absent. If the air environment deviates from the comfort zone, whether on the high side or on the low side, then the details for which guidance must be provided are stored in the control detailsfield 194. - (B) The air environmental factors of the room RM shown in
FIG. 1 may be at least two of the temperature, the dew point temperature differential, the humidity, the atmospheric pressure, the airflow, the toxic substance concentration, the dust concentration, and the negative ion concentration of the room RM. Here, toxic substances may be at least one of, for example, carbon monoxide, carbon dioxide, allergens, mites, mold, formaldehyde, organic compounds, VOCs (volatile organic compounds) and endocrine disrupters. In this case, thedetermination unit 12 shown inFIG. 2 may assign a priority order to the plurality of air environmental factors of the room RM, and may determine whether the air environment of the room RM is within the range of the comfort zone based on information about the air environment of the room RM and thecomfort zone information 18. For example, if the priority order is the temperature of the room RM and the dew point temperature differential of the room RM in that order, then, as long as the temperature of the room RM is within the range of the comfort zone, thedetermination unit 12 determines that the air environment of the room RM is within the range of the comfort zone even if the dew point temperature differential of the room RM is not within the range of the comfort zone. Thereby, it is possible to create a comfortable environment in the room RM while giving priority to those air environmental factors of the room RM that are important (e.g., the temperature of the room RM). - (C) The air environmental factors of the room RM shown in
FIG. 1 may be at least two of the temperature, the dew point temperature differential, the humidity, the atmospheric pressure, the airflow, the toxic substance concentration, the dust concentration, and the negative ion concentration of the room RM. Here, toxic substances may be at least one of, for example, carbon monoxide, carbon dioxide, allergens, mites, mold, formaldehyde, organic compounds, VOCs (volatile organic compounds) and endocrine disrupters. In this case, thegeneration unit 13 shown inFIG. 2 may assign a priority order to the plurality of air environmental factors of the room RM, and, based on the information about the determination result of thedetermination unit 12 and the information about the air environment of the room RM, may generate the control signal so that the air environment of the room RM falls within the range of the comfort zone. Let us consider an example of a case wherein the priority order is the temperature of the room RM and the dew point temperature differential of the room RM in that order. As shown inFIG. 5 , a control signal to perform “automatic operation with the temperature set to 24° C.” is generated if the room RM temperature is 19° C. or less. Moreover, a control signal to perform “ventilation operation with ‘high’ airflow” is generated if the dew point temperature differential of the room RM is 0° C. or less. In this case, if ventilation is forcibly performed even though the room RM temperature is below the comfort zone, then the temperature of the room RM will fall even further below the comfort zone. Accordingly, thegeneration unit 13 generates the control signal based only on the control detail of “automatic operation with the temperature set to 24° C.” instead of “ventilation operation with ‘high’ airflow.” Accordingly, a priority order is assigned to a plurality of air environmental factors and a control signal is generated so that the air environment of the room RM falls within the range of the comfort zone, and therefore, if there is a plurality of control details, the control signal can be generated by adjusting such. - (D) The details of the control signal generated by the
generation unit 13 shown inFIG. 2 may be at least one of the operation mode, the set temperature, the set humidity, the set airflow, the set wind direction, the amount of dehumidification, the amount of humidification, the amount of ventilation, and the air cleaning performance of theair conditioner 20. Accordingly, it is possible to generate a control signal for at least one of the operation mode, the set temperature, the set humidity, the set airflow, the set wind direction, the amount of dehumidification, the amount of humidification, the amount of ventilation, and the air cleaning performance of theair conditioner 20, and it is therefore possible to finely create a comfortable air environment in the room RM. - (E) As shown in
FIG. 2 , theenvironmental control apparatus 10 shown inFIG. 1 may comprise asetting unit 16 and aninput unit 17. Namely, a sense of comfort with respect to the air environment of the room RM is input to theinput unit 17. The settingunit 16 receives the information about the sense of comfort from theinput unit 17. The settingunit 16 sets the comfort zone of the air environment of the room RM based on the information about the sense of comfort. Thestorage unit 15 receives the information about the comfort zone, which was set by the settingunit 16, from the settingunit 16. Thestorage unit 15 stores the comfort zone, which was set by the settingunit 16. Namely, the settingunit 16 overwrites thecomfort zone information 18 of thestorage unit 15 by replacing the default information with the comfort zone information set by the settingunit 16. - The fact that the environment is comfortable may be input to the
input unit 17 by, for example, pressing aforehead 34 or astomach 33, or by shaking ahand 32 of the environmental control apparatus 10 (Pichon-kun) shown inFIG. 1 . Alternatively, such an input may be made to theinput unit 17 by saying, for example, “I'm comfortable,” via a voice device such as a microphone. The present embodiment differs from the first embodiment on these points. - In addition, as shown in
FIG. 6 , the flow of the process wherein theenvironmental control system 1 shown inFIG. 1 controls the air environment of the room RM differs from the first embodiment on the following points. Furthermore, processes in the flow chart shown inFIG. 6 that are the same as those shown inFIG. 3 are assigned the same symbols, and the explanation thereof is omitted. - In step S11 shown in
FIG. 6 , the user of theenvironmental control apparatus 10 shown inFIG. 1 determines whether the air environment of the room RM is comfortable. The process proceeds to step S12 if it is determined that it is comfortable, or proceeds to step S1 if it is determined that it is not comfortable. - In step S12 shown in
FIG. 6 , the user of theenvironmental control apparatus 10 shown inFIG. 1 inputs the sense of comfort for the air environment of the room RM. Namely, the sense of comfort with respect to the air environment of the room RM is input to theinput unit 17 of theenvironmental control apparatus 10 shown inFIG. 2 . The settingunit 16 receives the information about the sense of comfort from theinput unit 17. - In step S13 shown in
FIG. 6 , the air environment of the room RM shown inFIG. 1 is sensed. Namely, thesensor unit 11 of theenvironmental control apparatus 10 shown inFIG. 2 senses the air environment of the room RM. The settingunit 16 receives the information about the air environment of the room RM from thesensor unit 11. - In step S14 shown in
FIG. 6 , the comfort zone of the air environment of the room RM shown inFIG. 1 is set. Namely, the settingunit 16 shown inFIG. 2 sets the comfort zone of the air environment of the room RM based on the information about the sense of comfort. For example, if it is comfortable when the temperature of the room RM is 21° C., then the center of the zone of 20°-26° C. (refer toFIG. 4 ), which is the temperature comfort zone of the room RM, is shifted from 23° C. to 21° C., and the temperature comfort zone of the room RM is set to 18°-24° C. - In step S15 shown in
FIG. 6 , the comfort zone of the air environment of the room RM shown inFIG. 1 is stored. Namely, thestorage unit 15 shown inFIG. 2 receives the information about the comfort zone, which was set by the settingunit 16, from the settingunit 16. Thestorage unit 15 stores the comfort zone that was set by the settingunit 16. Namely, thestorage unit 15 overwrites thecomfort zone information 18 by replacing the default information with the comfort zone information set by the settingunit 16. - Accordingly, the comfort zone of the air environment of the room RM shown in
FIG. 1 is set based on the information about the user's sense of comfort, and it is therefore possible to determine the comfort zone for each user. Consequently, it is possible to create a comfortable air environment in the room RM in accordance with the user's preference. In addition, the comfort zone set by the setting unit 16 (refer toFIG. 2 ) is stored, and it is therefore possible to reference the information about the comfort zone set by the settingunit 16. Consequently, it is possible to generate the control signal so that the air environment of the room RM falls within the range of the user's preferred comfort zone. - Furthermore, step S15 shown in
FIG. 6 may be omitted. In this case, the comfort zone is modified only when the sense of comfort is input to theinput unit 17 shown inFIG. 2 , and, at other times, thecomfort zone information 18 is set to the default information about the comfort zone. In this case, thecomfort zone information 18 remains set to the default information and is not overwritten. The comfort zone information set by the settingunit 16 is passed to thedetermination unit 12 without going through thestorage unit 15. - In addition, if it is determined in step S11 shown in
FIG. 6 that the air environment is not comfortable, then the fact that the environment is uncomfortable is input to theinput unit 17 shown inFIG. 2 . In this case, the settingunit 16 may set the comfort zone of the air environment of the room RM so that it deviates from the air environment considered to be uncomfortable. - (F) As shown in
FIG. 2 , theenvironmental control apparatus 10 shown inFIG. 1 may comprise acalculation unit 28. In this case, thecalculation unit 28 receives information about the air environment of the room RM from thedetermination unit 12. Thecalculation unit 28 calculates the amount of energy needed for theair conditioner 20 to condition the air environment of the room RM. Here, the amount of energy is the amount of electric power. Thedetermination unit 12 receives information about the amount of energy from thecalculation unit 28 and further determines whether that amount of energy exceeds a prescribed target upper limit value. Thegeneration unit 13 receives information about whether the amount of energy exceeds the prescribed target upper limit value from thedetermination unit 12. If thegeneration unit 13 receives information to the effect that the amount of energy exceeds the prescribed target upper limit value, then it modifies the control signal by modifying the control details. Namely, based on the information about the determination result of thedetermination unit 12, thegeneration unit 13 generates the control signal so that the amount of energy does not exceed the prescribed target upper limit value and so that the air environment of the room falls within the range of the comfort zone. The present embodiment differs from the first embodiment on these points. - In addition, as shown in
FIG. 7 , the flow of the process wherein theenvironmental control system 1 shown inFIG. 1 controls the air environment of the room RM differs from the first embodiment on the following points. Furthermore, processes in the flow chart shown inFIG. 7 that are the same as those shown inFIG. 3 are assigned the same symbols, and the explanation thereof is omitted. - In step S21 shown in
FIG. 7 , the needed amount of energy is calculated. Namely, thecalculation unit 28 of theenvironmental control apparatus 10 shown inFIG. 2 receives information about the air environment of the room RM from thedetermination unit 12. Thecalculation unit 28 calculates the amount of energy needed for theair conditioner 20 to condition the air environment of the room RM. Thedetermination unit 12 receives the information about the amount of energy from thecalculation unit 28. - In step S22 shown in
FIG. 7 , thedetermination unit 12 shown inFIG. 2 determines whether the amount of energy exceeds the prescribed target upper limit value. If it is determined that the amount of energy exceeds the prescribed target upper limit value, then the process proceeds to step S23 shown inFIG. 7 , or, if it is determined that the amount of energy does not exceed the prescribed target upper limit value, then the process proceeds to step S4. - In step S23 shown in
FIG. 7 , the control signal is modified. Namely, thegeneration unit 13 of theenvironmental control apparatus 10 shown inFIG. 2 receives information to the effect that the amount of energy exceeds the prescribed target upper limit value. Thegeneration unit 13 modifies the control signal by modifying the control details. - Accordingly, the
air conditioner 20 can be controlled so that the amount of energy does not exceed the target upper limit value and so that the air environment of the room RM shown inFIG. 1 falls within the range of the comfort zone, and it is therefore possible to create a comfortable air environment in the room RM while conserving energy. - Furthermore, the determination of step S22 shown in
FIG. 7 may be made by thegeneration unit 13. In this case, in step S21 shown inFIG. 7 , thegeneration unit 13 receives information about the amount of energy from thecalculation unit 28. The amount of energy may be at least one of, for example, the amount of electric power, the amount of gas, the amount of water, and the amount of petroleum (gasoline and the like). - (G) As shown in
FIG. 8 , anenvironmental control system 1 a may comprise anenvironmental control apparatus 10 a and anair conditioner 20 a. As shown inFIG. 9 , theenvironmental control apparatus 10 a may also be constituted without the generation unit 13 (refer toFIG. 2 ). Theair conditioner 20 a may comprise acontrol unit 23 a. In this case, thesend unit 14 receives information about the determination result of adetermination unit 12 a from thedetermination unit 12 a. Thesend unit 14 sends the information about the determination result of thedetermination unit 12 a to theair conditioner 20 a via a wireless circuit. Thereception unit 21 of theair conditioner 20 a receives information about the determination result of thedetermination unit 12 a from theenvironmental control apparatus 10 a via the wireless circuit. Thecontrol unit 23 a of theair conditioner 20 a receives information about the determination result of thedetermination unit 12 a from thereception unit 21, and generates a control signal so that the air environment of the room RM (refer toFIG. 8 ) falls within the range of the comfort zone. Theenvironment providing unit 22 receives the control signal from thecontrol unit 23 a and provides the room RM with an air conditioned environment based on that control signal. The present embodiment differs from the first embodiment on these points. - In addition, as shown in
FIG. 10 , the flow of the process wherein theenvironmental control system 1 a shown inFIG. 8 controls the air environment of the room RM differs from the first embodiment on the following points. Processes in the flow chart shown inFIG. 10 that are the same as those shown inFIG. 3 are assigned the same symbols, and the explanation thereof is omitted. - In step S31 shown in
FIG. 10 , the information about the determination result is sent. Namely, thesend unit 14 of theenvironmental control apparatus 10 a shown inFIG. 9 receives the information about the determination result of thedetermination unit 12 a from thedetermination unit 12 a. Thesend unit 14 sends the information about the determination result of thedetermination unit 12 a to theair conditioner 20 a via the wireless circuit. - In step S32 shown in
FIG. 10 , the control signal is generated. Namely, thereception unit 21 of theair conditioner 20 a shown inFIG. 9 receives the information about the determination result of thedetermination unit 12 a from theenvironmental control apparatus 10 a via the wireless circuit. Thecontrol unit 23 a of theair conditioner 20 a receives the information about the determination result of thedetermination unit 12 a from thereception unit 21, and generates a control signal so that the air environment of the room RM falls within the range of the comfort zone. Theenvironment providing unit 22 receives the control signal from thecontrol unit 23 a. - Accordingly, information about whether the air environment of the room RM shown in
FIG. 8 is within the range of the comfort zone is sent to theair conditioner 20 a, and it is therefore possible for theair conditioner 20 a to set the control signal so that the air environment of the room RM falls within the range of the comfort zone. Consequently, it is possible to enable theair conditioner 20 a to control the air environment of the room RM so that it falls within the range of the comfort zone without making the user aware of the comfort zone. As a result, it is possible to automatically create a comfortable air environment in the room RM without making the user aware of such. - (H) In the modified example (G) of the first embodiment, the
environmental control apparatus 10 a may further comprise thecalculation unit 28. In this case, thecalculation unit 28 calculates the amount of energy that is needed for theair conditioner 20 a to condition the air environment of the room RM. Thedetermination unit 12 a receives the information about the amount of energy from thecalculation unit 28. Based on the information about the air environment of the room RM, thedetermination unit 12 a determines whether the amount of energy exceeds the prescribed target upper limit value, and whether the air environment of the room RM is within the range of the comfort zone. The present embodiment differs from the modified example (G) of the first embodiment on these points. Accordingly, it is possible enable theair conditioner 20 a to control the amount of energy so that it does not exceed the target upper limit value and so that the air environment of the room RM falls within the range of the comfort zone, and it is therefore possible to create a comfortable air environment in the room RM while conserving energy. - (I) Information is sent from the
environmental control apparatus 10 shown inFIG. 1 to theair conditioner 20 via a wireless circuit, which may use infrared rays or electromagnetic waves. Instead of sending the information from theenvironmental control apparatus 10 to theair conditioner 20 via the wireless circuit, the information may be sent via a wired circuit. If the information is sent via a wired circuit, then the connection between theenvironmental control apparatus 10 and the wired circuit may be cut when theenvironmental control apparatus 10 is transported. At this time, theenvironmental control apparatus 10 and theair conditioner 20 may be further connected by a wireless circuit. Theair conditioner 20 may be not only a regular air conditioner, but also, for example, a cooler, a heater, a ventilator, a dehumidifier, a humidifier, or an air cleaner. There may be a plurality ofair conditioners 20. Theair conditioner 20 may be at least one of, for example, a regular air conditioner, a cooler, a heater, a ventilator, a dehumidifier, a humidifier, or an air cleaner. The external form of theenvironmental control apparatus 10 need not be that of Pichon-kun. For example, as long as it is portable, it may be: a stuffed animal; a folding chair, a table, or the like; a picture frame with a picture in it, or the like; or a desk lamp, a pencil box, or the like. -

FIG. 11 andFIG. 12 , the environmental control system 100 has the same basic structure as that of the first embodiment and its constituent elements are the same as those inFIG. 2 , but, as shown inFIG. 11 , differs from the first embodiment in that theenvironmental control apparatus 10 of the first embodiment is a mobile information terminal, such as a notebook computer, in the present embodiment. - The control signal is sent to the
air conditioner 20 so that the air environment of the room RM (refer toFIG. 11 ) falls within the range of the comfort zone, and it is therefore possible to control theair conditioner 20 so that the air environment falls within the range of the comfort zone without making the user aware of the comfort zone; the first embodiment is same on this point. Accordingly, such an environmental control system 100 can also automatically create a comfortable air environment in the room RM without making the user aware of such. - (A) An
input unit 117 shown inFIG. 12 may be akeyboard 132, which is shown inFIG. 11 .

Theenvironment providing unit 22 receives the control signal from thecontrol unit 23 a and provides the air conditioned environment to the room RM based on the control signal. The present embodiment differs from the first embodiment on these points. - In addition, the flow of the process wherein the
environmental control system 100 a shown inFIG. 13 controls the air environment of the room RM is the same as that in the modified example (G) of the first embodiment (refer toFIG. 10 ). - Accordingly, the information about whether the air environment of the room RM shown in
FIG. 13 is within the range of the comfort zone is sent to theair conditioner 20 a, and it is therefore possible for theair conditioner 20 a to set the control signal so that the air environment of the room RM falls within the range of the comfort zone. Consequently, it is possible to enable theair conditioner 20 a to control the air environment of the room RM so that it falls within the range of the comfort zone without making the user aware of such. As a result, it is possible to automatically create a comfortable air environment in the room RM without making the user aware of such. - (C) As shown in

In this case, thecalculation unit 28 calculates the amount of energy needed for theair conditioner 20 a to condition the air environment of the room RM. Thedetermination unit 12 a receives information about the amount of energy from thecalculation unit 28. Based on the information about the air environment of the room RM, thedetermination unit 12 a determines whether the amount of energy exceeds the prescribed target upper limit value and whether the air environment of the room RM is within the range of the comfort zone. The present embodiment differs from the modified example (B) of the second embodiment on these points. Accordingly, it is possible to enable theair conditioner 20 a to control the amount of energy so that it does not exceed the target upper limit value and so that the air environment of the room RM (refer toFIG. 13 ) falls within the range of the comfort zone, and it is therefore possible to create a comfortable air environment in the room RM while conserving energy. -

Here, the information about the determination result of thedetermination unit 212 is information about whether the air environment of the room RM is within the range of the comfort zone. Therecommendation unit 213 references thestorage unit 215 and acquiresrecommendation information 219. Based on the information about the determination result of thedetermination unit 212 and the information about the air environment of the room RM, therecommendation unit 213 recommends a method of improving the air environment of the room RM so that it falls within the range of the comfort zone. Thevocalization unit 214 receives information about the improving method from therecommendation unit 213. Based on the information about the improving method recommended by therecommendation unit 213, thevocalization unit 214 reports the improving method by using speech. Namely, guidance is provided on the air environment of the room RM. - The
comfort zone information 218 shown inFIG. 16 indicates various cases in which the air environment of the room RM is within the range of the comfort zone.

- Here, the
vocalization unit 214 receives information about the improving method from therecommendation unit 213. Based on the information about the improving method recommended by therecommendation unit 213, thevocalization unit 214 reports the improving method by using speech. - Accordingly, it is possible to easily ascertain the improving method.

Furthermore, the information about the air environment of the room RM stored in thestorage unit 215 may be analyzed. Thevocalization unit 214 shown inFIG. 16 may report the improving method via, for example, a speaker (not shown) that is installed in the vicinity of amouth 231 of Pichon-kun (refer toFIG. 15 ). Based on the determination result of thedetermination unit 212, therecommendation unit 213 may recommend a method of improving the air environment of the room RM so that it falls within the range of the comfort zone. In this case, thelower limit field 219B and theupper limit field 219C shown inFIG. 19 may be omitted. Regardless of whether the air environment of the room RM is above or below the comfort zone, the details for which guidance is provided if the air environment of the room RM deviates from the comfort zone may be stored in the guidance detailsfield 219D. - (B) The air environmental factors of the room RM shown in
FIG. 15 may be at least two of the temperature, the dew point temperature differential, the humidity, the atmospheric pressure, the airflow, the toxic substance concentration, the dust concentration, and the negative ion concentration of the room RM. Here, toxic substances may be at least one of, for example, carbon monoxide, carbon dioxide, allergens, mites, mold, formaldehyde, organic compounds, VOCs (volatile organic compounds), and endocrine disrupters. In this case, thedetermination unit 212 shown inFIG. 16 may assign a priority order to the plurality of air environmental factors of the room RM, and may determine whether the air environment of the room RM is within the range of the comfort zone based on information about the air environment of the room RM. For example, if the priority order is the temperature of the room RM and the dew point temperature differential of the room RM in that order, then, as long as the temperature of the room RM is within the range of the comfort zone, thedetermination unit 212 determines that the air environment of the room RM is within the range of the comfort zone even if the dew point temperature differential of the room RM is not within the range of the comfort zone. Thereby, it is possible to create a comfortable environment in the room RM while giving priority to those air environmental factors of the room RM that are important (e.g., the temperature of the room RM). - (C) The air environmental factors of the room RM shown in
FIG. 15 may be at least two of the temperature, the dew point temperature differential, the humidity, the atmospheric pressure, the airflow, the toxic substance concentration, the dust concentration, and the negative ion concentration of the room RM. Here, toxic substances may be at least one of, for example, carbon monoxide, carbon dioxide, allergens, mites, mold, formaldehyde, organic compounds, VOCs (volatile organic compounds), and endocrine disrupters. In this case, therecommendation unit 213 shown inFIG. 16 may assign a priority order to the plurality of air environmental factors of the room RM, and, based on the information about the determination result of thedetermination unit 212 and the information about the air environment of the room RM, may recommend a method of improving the air environment of the room RM so that it falls within the range of the comfort zone. Let us consider an example of a case wherein the priority order is the temperature of the room RM and the dew point temperature differential of the room RM in that order. As shown inFIG. 19 , a guidance of the air conditioner operation method such as “please perform operation with the temperature set to 24° C.” is provided if the room RM temperature is 19° C. or less. However, a guidance of the ventilation method such as “please open the window for two minutes” is provided if the dew point temperature differential of the room RM is 0° C. or less. In this case, if the window is opened regardless of whether the room RM temperature is below the comfort zone, then the temperature of the room RM will fall even further below the comfort zone. Accordingly, instead of using the guidance details of “please open the window for two minutes,” therecommendation unit 213 provides guidance on just the air conditioner operation method of “please set the temperature to 24° C.” Accordingly, a priority order is assigned to a plurality of air environmental factors and a recommendation is made on a method of improving the air environment of the room RM so that it falls within the range of the comfort zone, and therefore, if there is a plurality of improving methods, a coordinated recommendation can be made. - (D) The air conditioner (not shown) operation method of the improvement methods recommended by the
recommendation unit 213 shown inFIG. 16 may be an improvement method for at least one of the operation mode, the set temperature, the set humidity, the set airflow, the set wind direction, the amount of dehumidification, the amount of humidification, the amount of ventilation, and the air cleaning performance of the air conditioner. Accordingly, it is possible to recommend an improving method for at least one of the operation mode, the set temperature, the set humidity, the set airflow, the set wind direction, the amount of dehumidification, the amount of humidification, the amount of ventilation, and the air cleaning performance of the air conditioner, and it is therefore possible to finely create a comfortable air environment in the room RM. - (E) As shown in
FIG. 16 , theenvironmental guidance apparatus 210 shown inFIG. 15 may comprise asetting unit 216 and aninput unit 217. Namely, a sense of comfort with respect to the air environment of the room RM is input to theinput unit 217. Thesetting unit 216 receives the information about the sense of comfort from theinput unit 217. Thesetting unit 216 sets the comfort zone of the air environment of the room RM based on the information about the sense of comfort. Thestorage unit 215 receives the information about the comfort zone, which was set by thesetting unit 216, from thesetting unit 216. Thestorage unit 215 stores the comfort zone, which was set by thesetting unit 216. Namely, thesetting unit 216 overwrites thecomfort zone information 218 of thestorage unit 215 by replacing the default information with the comfort zone information set by thesetting unit 216. - The fact that the environment is comfortable may be input to the
input unit 217 by, for example, pressing aforehead 234 or astomach 233, or by shaking ahand 232 of the environmental guidance apparatus 210 (Pichon-kun) shown inFIG. 15 . Alternatively, such an input may be made to theinput unit 217 by saying, for example, “I'm comfortable,” via a voice device such as a microphone. The present embodiment differs from the third embodiment on these points. - In addition, the flow of the process wherein the
environmental guidance system 210 shown inFIG. 15 provides guidance on the air environment of the room RM differs from the third embodiment on the following points. Furthermore, processes in the flow chart shown inFIG. 20 that are the same as those shown inFIG. 17 are assigned the same reference numbers. - In step S111 shown in
FIG. 20 , the user (not shown) of theenvironmental guidance apparatus 210 shown inFIG. 15 determines whether the air environment of the room RM is comfortable. The process proceeds to step S112 if it is determined that it is comfortable, or proceeds to step S101 if it is determined that it is not comfortable. - In step S112 shown in
FIG. 20 , the user of theenvironmental guidance apparatus 210 shown inFIG. 15 inputs the sense of comfort with respect to the air environment of the room RM. Namely, the sense of comfort with respect to the air environment of the room RM is input to theinput unit 217 of theenvironmental guidance apparatus 210 shown inFIG. 16 . Thesetting unit 216 receives the information about the sense of comfort from theinput unit 217. - In step S113 shown in
FIG. 20 , the air environment of the room RM shown inFIG. 15 is sensed. Namely, thesensor unit 211 of theenvironmental guidance apparatus 210 shown inFIG. 16 senses the air environment of the room RM. Thesetting unit 216 receives the information about the air environment of the room RM from thesensor unit 211. - In step S114 shown in
FIG. 20 , the comfort zone of the air environment of the room RM shown inFIG. 15 is set. Namely, thesetting unit 216 shown inFIG. 16 sets the comfort zone of the air environment of the room RM based on the information about the sense of comfort and information about the air environment of the room RM. For example, if it is comfortable when the temperature of the room RM is 21° C., then the center of the zone of 20°-26° C. (refer toFIG. 18 ), which is the temperature comfort zone of the room RM, is shifted from 23° C. to 21° C., and the temperature comfort zone of the room RM is set to 18°-24° C. - In step S115 shown in
FIG. 20 , the comfort zone of the air environment of the room RM shown inFIG. 15 is stored. Namely, thestorage unit 215 shown inFIG. 16 receives the information about the comfort zone, which was set by thesetting unit 216, from thesetting unit 216. Thestorage unit 215 stores the comfort zone that was set by thesetting unit 216. Namely, thestorage unit 215 overwrites thecomfort zone information 218 by replacing the default information with the comfort zone information set by thesetting unit 216. - Accordingly, the comfort zone of the air environment of the room RM shown in
FIG. 15 is set based on the information about the user's sense of comfort, and it is therefore possible to set the comfort zone for each user. Consequently, it is possible to create a comfortable air environment in the room RM in accordance with the user's preference. In addition, the comfort zone set by the setting unit 216 (refer toFIG. 16 ) is stored, and it is therefore possible to reference the information about the comfort zone set by thesetting unit 216. Consequently, it is possible to recommend a method of improving the air environment of the room RM so that it falls within the range of the user's preferred comfort zone. - Furthermore, step S115 shown in
FIG. 20 may be omitted. In this case, the comfort zone is modified only when the sense of comfort is input to theinput unit 217 shown inFIG. 16 , and, at other times, thecomfort zone information 218 is set to the default information about the comfort zone. In this case, thecomfort zone information 218 remains set to the default information and is not overwritten. The comfort zone information set by thesetting unit 216 is passed to thedetermination unit 212 without going through thestorage unit 215. - In addition, the fact that the environment is uncomfortable may be input to the input unit shown in
FIG. 16 . In this case, thesetting unit 216 may set the comfort zone of the air environment of the room RM so that it deviates from the air environment considered to be uncomfortable. - (F) The external form of the
environmental guidance apparatus 210 shown inFIG. 15 need not be that of Pichon-kun. For example, as long as it is portable, it may be: a stuffed animal; a folding chair, a table, or the like; a picture frame with a picture in it, or the like; or a desk lamp, a pencil box, or the like. -
FIG. 21 shows a conceptual diagram of anenvironmental guidance apparatus 310 according to the fourth embodiment of the present invention. In addition,FIG. 22 shows a block diagram of the constituent elements of theenvironmental guidance apparatus 310 according to the fourth embodiment of the present invention. Constituent elements of theenvironmental guidance apparatus 310 inFIG. 21 andFIG. 22 that are the same as those of theenvironmental guidance apparatus 210 inFIG. 15 andFIG. 16 are assigned the same reference numbers. Theenvironmental guidance apparatus 310 shown inFIG. 21 is principally installed in the room RM and is portable. Theenvironmental guidance apparatus 310 is, for example, a notebook computer. - As shown in
FIG. 21 andFIG. 22 , theenvironmental guidance apparatus 310 has the same basic structure as that of the third embodiment and its constituent elements are the same as those inFIG. 16 , but, as shown inFIG. 22 , differs from the third embodiment in that theenvironmental guidance apparatus 310 comprises adisplay unit 314 instead of the vocalization unit 214 (refer toFIG. 16 ). Namely, thedisplay unit 314 shown inFIG. 22 receives information about the improving method from therecommendation unit 213. Based on the information about the improving method recommended by therecommendation unit 213, thedisplay unit 314 reports the improving method by displaying such on a screen 335 (refer toFIG. 21 ). Accordingly, it is possible to easily ascertain the improving method because it is reported by displaying it on thescreen 335. - The point that a recommendation is made on a method of improving the air environment of the room RM so that it falls within the range of the comfort zone is the same as in the third embodiment. Accordingly, it is also possible to create a sufficiently comfortable air environment in the room RM by such an
environmental guidance apparatus 310. - (A) An
input unit 317 shown inFIG. 22 may be akeyboard 332, which is shown inFIG. 21 . In this case, detailed information concerning the sense of comfort with respect to the air environment of the room RM can be input. In addition, theenvironmental guidance apparatus 310 may be a mobile information terminal other than a notebook computer. For example, as long as it is portable, it may be a mobile telephone or an electronic organizer. - The environmental control apparatus, the environmental control system, the environmental control method, and the environmental control program according to the present invention are effective in that they can create a sufficiently comfortable air environment in a room, and are therefore useful for environmental control.
