Does everyone's air conditioning and ventilation function consume electricity?

Breathing is definitely more expensive than not changing the electricity. But from a health point of view, it's still worth it! So don't worry about this. After all, health can't be measured by money.

If you care about this, you can spend a few days recording the electricity consumption of the electricity meter, and compare the ventilation and non-ventilation, so you can get a general idea of the difference in electricity consumption.
