  • Such an input may be made to the input 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.
  • step S 111 shown in FIG. 20 the user (not shown) of the environmental guidance apparatus 210 shown in FIG. 15 determines whether the air environment of the room RM is comfortable. The process proceeds to step S 112 if it is determined that it is comfortable, or proceeds to step S 101 if it is determined that it is not comfortable.
  • step S 112 shown in FIG. 20 the user of the environmental guidance apparatus 210 shown in FIG. 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 the input unit 217 of the environmental guidance apparatus 210 shown in FIG. 16 .
  • the setting unit 216 receives the information about the sense of comfort from the input unit 217 .
  • step S 113 shown in FIG. 20 the air environment of the room RM shown in FIG. 15 is sensed.
  • the sensor unit 211 of the environmental guidance apparatus 210 shown in FIG. 16 senses the air environment of the room RM.

  • step S 114 shown in FIG. 20 the comfort zone of the air environment of the room RM shown in FIG. 15 is set.
  • the setting unit 216 shown in FIG. 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 to FIG. 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.
  • step S 115 shown in FIG. 20 the comfort zone of the air environment of the room RM shown in FIG. 15 is stored.
  • the storage unit 215 shown in FIG. 16 receives the information about the comfort zone, which was set by the setting unit 216 , from the setting unit 216 .
  • the storage unit 215 stores the comfort zone that was set by the setting unit 216 .
  • the storage unit 215 overwrites the comfort zone information 218 by replacing the default information with the comfort zone information set by the setting unit 216 .
  • 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.
  • the comfort zone set by the setting unit 216 (refer to FIG. 16 ) is stored, and it is therefore possible to reference the information about the comfort zone set by the setting 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.
  • step S 115 shown in FIG. 20 may be omitted.
  • the comfort zone is modified only when the sense of comfort is input to the input unit 217 shown in FIG. 16 , and, at other times, the comfort zone information 218 is set to the default information about the comfort zone. In this case, the comfort zone information 218 remains set to the default information and is not overwritten.
  • the comfort zone information set by the setting unit 216 is passed to the determination unit 212 without going through the storage unit 215 .
  • the setting 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.
  • the external form of the environmental guidance apparatus 210 shown in FIG. 15 need not be that of Pichon-kun.
  • 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 an environmental guidance apparatus 310 according to the fourth embodiment of the present invention.
  • FIG. 22 shows a block diagram of the constituent elements of the environmental guidance apparatus 310 according to the fourth embodiment of the present invention. Constituent elements of the environmental guidance apparatus 310 in FIG. 21 and FIG. 22 that are the same as those of the environmental guidance apparatus 210 in FIG. 15 and FIG. 16 are assigned the same reference numbers.
  • the environmental guidance apparatus 310 shown in FIG. 21 is principally installed in the room RM and is portable.
  • the environmental guidance apparatus 310 is, for example, a notebook computer.
  • the environmental guidance apparatus 310 has the same basic structure as that of the third embodiment and its constituent elements are the same as those in FIG. 16 , but, as shown in FIG. 22 , differs from the third embodiment in that the environmental guidance apparatus 310 comprises a display unit 314 instead of the vocalization unit 214 (refer to FIG. 16 ).
  • the display unit 314 shown in FIG. 22 receives information about the improving method from the recommendation unit 213 .
  • the display unit 314 reports the improving method by displaying such on a screen 335 (refer to FIG. 21 ). Accordingly, it is possible to easily ascertain the improving method because it is reported by displaying it on the screen 335 .
  • An input unit 317 shown in FIG. 22 may be a keyboard 332 , which is shown in FIG. 21 .
  • the environmental 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.
