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.

Abstract: The present invention relates to a method of controlling an RPM of a blower for a gas furnace that passes air to be supplied to a room around a heat exchanger of a gas furnace. The method includes: starting operation of the gas furnace; measuring an air temperature in an outlet side of the gas furnace; measuring the RPM of the blower; determining whether the air temperature falls within a reference temperature range; and adjusting the RPM of the blower such that the air temperature falls within the reference temperature range.

Abstract: An air conditioner and a method for controlling an air conditioner are provided. The method for controlling an air conditioner may include determining a user set temperature and performing an air cooling operation or an air heating operation in an indoor space; determining whether a user is present in the indoor space; when it is determined that the user is absent from the indoor space, counting an elapsed time; and when the elapsed time reaches a set time, performing a predetermined operation mode.
