Indoor unit of air-conditioning apparatus and air-conditioning apparatus

Abstract

An indoor unit includes: a casing formed with a suction port and a blow-out port; a plurality of fans provided in parallel in the casing; a heat exchanger provided on the downstream side of the fans and on the upstream side of the blow-out port; a horizontal wind direction control vane provided at the blow-out port to control the horizontal direction of an airflow blown out from the blow-out port; a vertical wind direction control vane provided at the blow-out port to control the vertical direction of the airflow blown out from the blow-out port; and an infrared ray human detection sensor configured to detect the position of a person present in a room, and air volumes, the orientation of the horizontal wind direction control vane, and the orientation of the vertical wind direction control vane of the fans are each controlled according to results of detection by the infrared ray sensor.

1 . An indoor unit of an air-conditioning apparatus comprising:
 a casing having a suction port formed in an upper portion and a blow-out port formed on a lower side of a front surface portion;   a plurality of axial-flow or mixed-flow fans provided in parallel on the downstream side of the suction port in the casing;   a heat exchanger provided on the downstream side of the fans and on the upstream side of the blow-out port in the casing and configured to exchange heat between air blown out from the fans and a refrigerant;   a horizontal wind direction control vane provided at the blow-out port and configured to control a horizontal direction of an airflow blown out from the blow-out port;   a vertical wind direction control vane provided at the blow-out port and configured to control a vertical direction of the airflow blown out from the blow-out port; and   a human detection sensor configured to detect a position of a person present in a room,   wherein air volume, an orientation of the horizontal wind direction control vane, and an orientation of the vertical wind direction control vane of the fans are each controlled according to detected results of the human detection sensor.   
     
     
         2 . The indoor unit of the air-conditioning apparatus of  claim 1 , wherein the horizontal wind direction control vane is divided into a plurality of horizontal wind direction control vanes,
 the vertical wind direction control vane is divided into the same number of vanes as the horizontal wind direction control vane, and   the divided horizontal wind direction control vanes and the vertical wind direction control vanes are controlled in terms of orientation individually.   
     
     
         3 . The indoor unit of the air-conditioning apparatus of  claim 2 , wherein the horizontal wind direction control vane and the vertical wind direction control vane are divided into the same number of parts as the number of the fans. 
     
     
         4 . The indoor unit of the air-conditioning apparatus of  claim 1 , wherein when there is a place where intensive air-conditioning is desired in a room, the air volume of a fan closest to the corresponding place is increased. 
     
     
         5 . The indoor unit of the air-conditioning apparatus of  claim 1 , wherein when there is a place where avoidance of the airflow blown out from the blow-out port is desired in the room, the air volume of a fan closest to the corresponding place is decreased. 
     
     
         6 . An air-conditioning apparatus comprising the indoor unit of the air-conditioning apparatus of  claim 1 .
