Air-conditioning apparatus

Abstract

An air-conditioning apparatus includes: an outdoor unit; and an indoor unit that is connected to the outdoor unit via a refrigerant pipe and performs air-conditioning of an indoor space in combination with the outdoor unit based on manipulation of a remote control. The outdoor unit includes: a stop switch and a return-to-operation switch; and a microcomputer that, when the stop switch is turned on while the indoor space is being air-conditioned, stops operation of the indoor and outdoor units, to stop performing air-conditioning of the indoor space, and that, when the return-to-operation switch is turned on while the air-conditioning of the indoor space is inactivated by turning on the stop switch, resumes the operation of the indoor unit to perform air-conditioning of the indoor space in combination with the outdoor unit.

1 . An air-conditioning apparatus comprising:
 an outdoor unit; and   an indoor unit that is connected to the outdoor unit via a refrigerant pipe and performs air-conditioning of an indoor space in combination with the outdoor unit based on manipulation of a remote control,   wherein the outdoor unit comprises:   a stop switch and a return-to-operation switch; and   an outdoor control unit that, when the stop switch is turned on while the indoor space is being air-conditioned, stops operation of the indoor and outdoor units to stop performing air-conditioning of the indoor space, and that, when the return-to-operation switch is turned on while the air-conditioning of the indoor space is inactivated by turning on the stop switch, resumes the operation of the indoor unit to perform air-conditioning of the indoor space in combination with the outdoor unit.   
     
     
         2 . The air-conditioning apparatus of  claim 1 , wherein the indoor unit comprises an indoor control unit that disables manipulation of the remote control when the operation is inactivated by turning on the stop switch. 
     
     
         3 . The air-conditioning apparatus of  claim 2 , wherein, when the manipulation of the remote control is disabled, the indoor control unit displays a notification that represents that the manipulation is disabled on a display of the remote control. 
     
     
         4 . The air-conditioning apparatus of  claim 2 , wherein the indoor control unit, when stopping performance of air-conditioning of the indoor space by turning on the stop switch, holds operating information before the stop, and, when resuming the operation by turning on the return-to-operation switch, returns to an operational state before the stop based on the operating information, so as to perform the air-conditioning of the indoor space in combination with the outdoor unit. 
     
     
         5 . The air-conditioning apparatus of  claim 1 , wherein the outdoor control unit starts a trial run when the operation is in an inactivated state due to turning on the stop switch and if ON time of the return-to-operation switch is longer than a first set time and equal to or shorter than a second set time, the second set time being longer than the first set time, and stops the trial run when the trial run has been performed and if the ON time of the return-to-operation switch is longer than the second set time.
