Disclosed herein is an air conditioner and control method of determining duration to be maintained at a reference temperature of a mode change based on an outdoor temperature. The air conditioner includes a compressor, an outdoor heat exchanger, an indoor heat exchanger, a four-way valve configured to guide refrigerant compressed in the compressor to either the outdoor heat exchanger or the indoor heat exchanger according to a cooling mode or a heating mode, and a controller configured to determine duration corresponding to a measured outdoor temperature, change the heating mode to the cooling mode when the measured indoor temperature is maintained at a first reference indoor temperature or greater for the determined duration, and change the cooling mode to the heating mode when a measured indoor temperature is maintained at a second reference indoor temperature or less for the determined duration.

Air conditioner and control method to change an operating mode based on a duration of time determined based on an outdoor temperature

An air conditioner, a control device thereof, and a method of controlling the same are provided. The air conditioner includes a control device including a plurality of indoor unit operation changers, and an indoor unit connected to any one of the plurality of indoor unit operation changers, where at least one of the indoor unit and the control device determines an operation mode of each of the plurality of indoor unit operation changers respectively connected to a plurality of indoor units, detects an indoor unit operation changer at an operation mode corresponding to an operation of any one of the plurality of indoor units among the plurality of indoor unit operation changers, and determines an indoor unit operation changer connected to the indoor unit among the plurality of indoor unit operation changers on based on a result of detecting at least one of the indoor unit operation changers.

Air conditioner, control device thereof, and method of controlling the same

An air cleaning system having at least one dust sensor and a method for controlling the air cleaning system may improve accuracy of dust sensors through linkage control of the dust sensors, and may normally operate a faulty air cleaner using dust sensors of the remaining communicating air cleaners other than the faulty air cleaner even when any one of the dust sensors fails to operate. The air cleaning system may select a master dust sensor through linkage control of the dust sensors, and may operate the plurality of air cleaners only using sensor information of the master dust sensor. Therefore, the air cleaning system may stop operation of the remaining dust sensors other than the master dust sensor, may reduce measurement noise produced by the dust sensors and power consumption, and may increase a lifetime of the dust sensors.

Air cleaning system and method for controlling the same

The present disclosure relates to an air conditioner, an air conditioner controlling system, and an air conditioner controlling method. The air conditioner controlling system includes one or more controlled air conditioners, a main controlling air conditioner having control authority over, from among the one or more controlled air conditioners, one or more controlled air conditioners that belong to an upper rank group corresponding to the main controlling air conditioner, and a sub-controlling air conditioner having control authority over, from among the one or more controlled air conditioners, one or more controlled air conditioners that belong to a first lower rank group.

Air conditioner controlling system and air conditioner controlling method

Provided is an air conditioning apparatus, a central control apparatus of the air conditioning apparatus, a remote control apparatus of the air conditioning apparatus, an indoor apparatus of the air conditioning apparatus and a method of controlling thereof. The central control apparatus of the air conditioning apparatus includes: a plurality of branched ports connected to a pipe of a plurality of indoor apparatuses and provided with predetermined identification information; and a central controller configured to identify the plurality of indoor apparatuses connected through the branched port, based on the identification information, and configured to control an operation of components contained in the air conditioning apparatus based on a result of the identification.

Air conditioning apparatus, central control apparatus of the air conditioning apparatus, remote control apparatus of the air conditioning apparatus, indoor apparatus of the air conditioning apparatus and method of controlling thereof
