PROBLEM TO BE SOLVED: To provide an amenity sensor capable of giving a measure of the amenity sensed by persons faithfully and easily, and to provide an air conditioner capable of performing truly comfortable air conditioning control economically.SOLUTION: Near infrared light is delivered to a prefrontal area part 2a of a brain by means of an LED light source 3 and receives the near infrared light transmitted by brain surface of the prefrontal area part 2a with a detector 4. Therein, the near infrared light received by the detector 4 is analyzed according to a near infrared spectroscopy and a density change of oxy-HB on the brain surface of the prefrontal area part 2a is calculated by an amenity calculator 10. An amenity sensor 1 analyzes a brain activation reaction of the prefrontal area part 2a on the basis of the density change of the oxy-HB calculated by the amenity calculator 10 and estimates the amenity sensed by persons from the analyzed brain activation reaction. An air conditioner 21 performs the air conditioning of a room 31 without waste on the basis of the amenity faithfully reflected by the amenity sensed by persons, which is detected by the amenity sensor 1.COPYRIGHT: (C)2014,JPO&INPIT【課題】 人の感じる快適度を忠実かつ容易に指標することの出来る快適度センサ、および真に快適な空調制御を経済的に行うことが可能な空気調和装置を提供する。【解決手段】 LED光源3によって脳の前頭前野部2aへ近赤外光を送出し、前頭前野部2aの脳表を透過した近赤外光を検出器4によって受光する。そして、検出器4で受光された近赤外光を近赤外分光法によって分析して、前頭前野部2aの脳表におけるoxy-HBの濃度変化を快適度演算器10によって算出する。快適度センサ1は、この快適度演算器10によって算出されたoxy-HBの濃度変化に基づいて前頭前野部2aの脳賦活反応を解析し、解析したこの脳賦活反応から人の感じる快適度を推測する。空気調和装置21は、快適度センサ1によって検知される、人の感じる快適度を忠実に反映した快適度に基づいて、部屋31の空調制御を無駄なく行う。【選択図】 図1
