A study found that waste heat generated by a city’s worth of air conditioners during a heatwave can raise the outside temperature by more than 2 degrees Celsius.
The 8kw you moved are. It irrelevant. The problem is that you consider the system as a whole, but that’s not how it works. If you consider the transfers like that, interior and exterior are 2 different systems, and the exterior system does get this 8kw time tens of thousands to units in the city. You modify the air flow and amplify the heat. The 2kw of energy used is added to city, sure, and that’s also significant, but “simply moving the heat” also has an effect.
