Air-conditioning apparatus and installation-position determination method

Abstract

An air-conditioning apparatus includes an outdoor unit, a plurality of indoor units installed in an air-conditioning target space, and a remote control. The plurality of indoor units include respective temperature sensors configured to detect indoor temperatures that are respective temperatures of indoor air to be sucked into the plurality of indoor units. The remote control includes a remote-control-side controller configured to control the outdoor unit and the plurality of indoor units. The remote-control-side controller is configured to determine relative installation positions of the plurality of indoor units based on the indoor temperatures detected at the plurality of indoor units.

1 . An air-conditioning apparatus comprising an outdoor unit, a plurality of indoor units installed in an air-conditioning target space, and a remote control,
 wherein   the plurality of indoor units include respective temperature sensors configured to detect indoor temperatures that are respective temperatures of indoor air to be sucked into the plurality of indoor units,   the remote control is configured to   control the outdoor unit and the plurality of indoor units,   store in advance a threshold for a temperature difference between an indoor temperature detected at a reference indoor unit and indoor temperatures detected at ones of the plurality of indoor units that are other than the reference indoor unit, when a specific one of the plurality of indoor units is selected as the reference indoor unit. and   compare, with the threshold, the temperature difference obtained when the reference indoor unit is operated. and determine relative installation positions of the ones of the plurality of indoor units that are other than the reference indoor unit, to the reference indoor unit.   
     
     
         2 - 3 . (canceled) 
     
     
         4 . The air-conditioning apparatus of  claim 1 , wherein the remote control is configured to determine that the smaller the temperature difference, the closer another one of the other indoor units to the reference indoor unit. 
     
     
         5 . (canceled) 
     
     
         6 . The air-conditioning apparatus of  claim 1 , wherein the remote control is configured to
 sequentially select the plurality of indoor units one by one as the reference indoor unit, and determine the relative installation positions of the other ones of the plurality of indoor units to the reference indoor unit as which the plurality of indoor units are sequentially selected one by one, and   determine, based on the determined relative installation positions of the other ones of the plurality of indoor units, the relative installation positions of all the plurality of indoor units to the reference unit as which the plurality of indoor units are sequentially selected one by one.   
     
     
         7 . The air-conditioning apparatus of  claim 1 , wherein
 the reference indoor unit includes a louver configured to cause blowing air to flow in an up-down direction, and   the remote control is configured to control the reference indoor unit such that the louver faces upward, when the remote-control-side controller determines the relative installation positions of the other ones of the plurality of indoor units to the reference indoor unit.   
     
     
         8 . The air-conditioning apparatus of  claim 1 , wherein
 the reference indoor unit includes a louver configured to cause blowing air to flow in a lateral direction, and is capable of causing the blowing air to flow in the left-right direction, and   the remote control is configured to control the reference indoor unit such that the louver continuously operates to swing in the left-right direction, when the remote control determines the relative installation positions of the other ones of the plurality of indoor units to the reference indoor unit.   
     
     
         9 . The air-conditioning apparatus of  claim 1 , wherein the remote control is configured to set a set temperature of the reference indoor unit to a temperature obtained by adding or subtracting a preset value to or from the indoor temperature detected at the reference indoor unit. 
     
     
         10 . (canceled) 
     
     
         11 . An air-conditioning apparatus comprising an outdoor unit, a plurality of indoor units installed in an air-conditioning target space, and a remote control,
 wherein   the plurality of indoor units include respective temperature sensors configured to detect indoor temperatures that are respective temperatures of indoor air to be sucked into the plurality of indoor units,   the remote control is configured to control the outdoor unit and the plurality of indoor units,   a reference unit as which a specific one of the plurality of indoor units is selected includes a louver configured to cause blowing air to flow in an up-down direction, and   the remote control is configured to
 control the reference indoor unit in such a manner as to cause the louver to face upward, 
 determine relative installation positions of ones of the plurality of indoor units that are other than the reference indoor unit, to the reference indoor unit, based on the indoor temperatures detected at the plurality of indoor units. 
   
     
     
         12 . An air-conditioning apparatus comprising an outdoor unit, a plurality of indoor units installed in an air-conditioning target space, and a remote control,
 wherein   the plurality of indoor units include respective temperature sensors configured to detect indoor temperatures that are respective temperatures of indoor air to be sucked into the plurality of indoor units,   the remote control is configured to control the outdoor unit and the plurality of indoor units,   a reference unit as which a specific one of the plurality of indoor units is selected includes a louver capable of causing blowing air to flow in a lateral direction, and   the remote control is configured to
 control the reference indoor unit in such a manner as to cause the louver to continuously swing in the lateral direction, 
 determine relative installation positions of ones of the plurality of indoor units that are other than the reference indoor unit, to the reference indoor unit, based on the indoor temperatures detected at the plurality of indoor units.
