Abstract
A method for controlling a gas furnace that performs a heating operation by receiving a first heating signal; calculating a certain heating capacity smaller than a maximum heating capacity of the gas furnace, according to the first heating signal; and operating a heating of the gas furnace with the calculated certain heating capacity. The calculating of the certain heating capacity includes calculating the certain heating capacity according to a difference between an intake air temperature sucked into the gas furnace and a reference temperature.
Claims10
A method for controlling a gas furnace that performs heating operation, the method comprising:
- receiving a first heating signal;
- calculating a certain heating capacity smaller than a maximum heating capacity of the gas furnace, according to the first heating signal;
- and
- operating a heating of the gas furnace with the calculated certain heating capacity, wherein the calculating of the certain heating capacity comprises calculating the certain heating capacity according to a difference between an intake air temperature sucked into the gas furnace and a reference temperature, wherein the intake air temperature is variable over time, wherein the reference temperature is set to a specific temperature higher than a specific intake air temperature at a certain time point among the variable intake air temperature, and wherein the certain heating capacity is varied in a stepwise manner according to a magnitude of a temperature difference obtained by subtracting the intake air temperature from the reference temperature, based on a preset starting capacity.
