 first and second high-temperature hot-air vents are disposed opposite to the high-temperature air channel,   the low-temperature hot-air vent is disposed opposite to the low-temperature air channel,   a damper is configured to control an airflow from the high-temperature air channel and the low-temperature air channel into the first high-temperature hot-air vent and the low-temperature hot-air vent,   an edge section of the divider on the side of the damper opposing the damper extends to a region in the vicinity of the damper, and   the other edge section of the divider extends to the vicinity of the second high-temperature hot-air vent.   
   
   
       4 . The air-conditioning unit according to  claim 2 , wherein,
 the heated air flows from the side of the high-temperature air channel into the high-temperature air channel and the low-temperature air channel,   the cooled air flows from the side of the low-temperature air channel into the high-temperature air channel and the low-temperature air channel, and   an area control unit configured to control the inlet area of the high-temperature air channel and the inlet area of the low-temperature air channel is provided on the edge of the divider.   
   
   
       5 . The air-conditioning unit according to  claim 2 , wherein,
 the heated air flows from the side of the high-temperature air channel into the high-temperature air channel and the low-temperature air channel,   the cooled air flows from the side of the low-temperature air channel into the high-temperature air channel and the low-temperature air channel, and   an end-moving section is configured to move the end position on the air inflow side of the divider in the airflow direction.   
   
   
       6 . An air-conditioning unit comprising:
 a chassis;   a cooling unit configured to cool air introduced into the chassis;   a heating unit configured to heat air introduced into the chassis; and   a conditioned-air channel configured to guide the heated air and the cooled air into a high-temperature hot-air vent and a low-temperature hot-air vent;   wherein,   
     the heated air flows into the conditioned-air channel from the side provided with an inlet to the high-temperature hot-air vent of the conditioned-air channel,
 the cooled air flows into the conditioned-air channel from the side provided with an inlet to the low-temperature hot-air vent of the conditioned-air channel, 
 one of the inlets to the high-temperature hot-air vent and the low-temperature hot-air vent is provided on the air inflow side of the conditioned-air channel, and 
 the other one of the inlets to the high-temperature hot-air vent and the low-temperature hot-air vent is provided on the air outflow side of the conditioned-air channel.
