The large burner in my stove is rated for 15K BTU. Does this mean that turning it on will counter 15K BTU from the capacity of my A/C unit? That turning all the burners will effectively negate the A/C entirely (if they add up to the A/C rating). That A/C on and all burners going = A/C off and all burners off?
I am considering installing A/C on the living areas and this is the type of detail that A/C installers seem to be clueless about and might make a huge difference.
Yes, in the case of an appliance with electric resistance heat the btu/hr rating is going to exactly offset the btu/hr rating of your cooling system. IF the appliance is in use 24 hours/day.
In reality a reasonable duty cycle of the appliance along with the btu/hr rating is used to estimate the cooling load in a cooling calculation.
Since most single-family dwellings with a kitchen have approximately the same appliances it’s likely to be pre-applied to any load calculation software or tables.
