<p><P>PROBLEM TO BE SOLVED: To provide a ceiling suspension type air conditioner capable of carrying out air conditioning control such that a temperature difference of a room becomes small by using a movable type radiation sensor, and having an energy saving effect. <P>SOLUTION: The ceiling suspension type air conditioner is characterized by that it is equipped with a casing 1 installed in a ceiling, a suction opening 3 provided on a rear part lower face or a rear part back face of the casing 1, an indoor blower provided in the casing 1 and blowing indoor air sucked in from the suction opening 3, an indoor heat exchanger arranged in a downstream side of the indoor blower in the casing 1 and carrying heat exchange between a coolant and the indoor air sent by the indoor blower, a blowout opening 6 provided in a front part of the casing 1 and blowing secondary air heat exchanged by the indoor heat exchanger into the room, a wind direction plate 8 arranged on the blowout opening 6 and turned vertically to control a vertical wind direction, and the radiation sensor 70 provided in the casing 1, detecting infrared ray radiated by an object such as the floor to detect a temperature of the object, driven by a driving part to turn a detection direction to the right and left, and detecting the temperature of the object such as the floor. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
