Abstract: Disclosed are an air conditioner and a control method therefor. The control method for an air conditioner includes: acquiring a top view image for an indoor space by using an imaging device and calculating a height of a ceiling in which an indoor unit is mounted; determining whether an image is a human body or an obstacle, with respect to at least one image included in the to view image; and performing control to allow air flow to avoid an obstacle and be discharged toward the human body by controlling driving of an indoor fan or a discharge vane provided in the indoor unit.

Abstract: The present invention relates to a method of controlling a gas furnace that performs heating operation according to a heating signal formed of one of a weak heating signal and a strong heating signal. The method includes: (a) receiving the heating signal; (b) determining whether the heating signal is the weak heating signal or the strong heating signal; (c) calculating a certain weak heating capacity smaller than a maximum heating capacity of the gas furnace, when the heating signal is the weak heating signal; and (d) operating a weak heating of the gas furnace with the calculated certain weak heating capacity, wherein the step (c) includes calculating the weak heating capacity according to a difference between a temperature of air (hereinafter, an intake air temperature) sucked into the gas furnace and a reference temperature set based on the intake air temperature.
