Abstract: An indoor air quality control method using an intelligent air cleaner is disclosed. An indoor air quality control method using an intelligent air cleaner according to an embodiment of the present invention classifies dust concentration data received from the air cleaner according to predetermined criteria and performs dust concentration pattern analysis. Particularly, dust concentration patterns for respective time periods are analyzed to control the air cleaning intensity of the air cleaner in advance of a predicted time, thereby facilitating efficient indoor air quality management. The intelligent air cleaner and the indoor air quality control method using the same of the present invention can be associated with artificial intelligence modules, devices related with the 5G service, and the like.

Abstract: An indoor air quality control method using an intelligent air cleaner is disclosed. An indoor air quality control method using an intelligent air cleaner according to an embodiment of the present invention can predict indoor dust concentration progress on the basis of output values of a learning model having received dust concentration data as input values when the dust concentration data of an indoor place where the air cleaner is located is received from the air cleaner, and determine whether ventilation is required by comparing the predicted progress with outside dust concentration data received from the Meteorological Administration server. Accordingly, indoor dust concentration changes can be predicted and an appropriate ventilation time can be recommended. The intelligent air cleaner and the indoor air quality control method using the same of the present invention can be associated with artificial intelligence modules, devices related with the 5G service, and the like.

Abstract: An air cleaner and a method for controlling an air cleaner are provided. The air cleaner may include a first air cleaning module having a first fan and a first filter; a second air cleaning module having a second fan and a second filter, the second air cleaning module provided vertically over the first air cleaning module; an air flow controller provided at an upper side of the second air cleaning module and including a circulation fan; a sensor configured to sense a pollution level in a room space; an input configured to receive input of a command for an operation mode of a plurality of operation modes to operate the first and second air cleaning modules and the air flow controller; and a controller configured to drive at least one of the first fan, the second fan, or the circulation fan selectively and determine an amount of discharge air flow. Based on at least one of an operation mode input or the pollution level, the controller may operate one of (1) the first fan, (2) the first and second fans, (3) the first and second fans and the circulation fan, or (4) the second fan and the circulation fan.
