The physics teacher once talked about the principle that overheated air rises and cold air sinks. Therefore, everyone should grasp this law when turning on the air conditioner in the car. When the air conditioner is turned on, the air outlet will go up, and when the warm air is turned on, the air outlet will go down.

The general automobile air conditioner has a pollen filter at the air inlet, which is used to prevent external dust from entering when the automobile air conditioner is externally circulated. When cleaning the air conditioner, remove the pollen filter, inject the foam cleaning agent into the air conditioner from the air inlet, and close the air outlet of the air conditioner to prevent the foam cleaning agent from flowing out of the air outlet. Then, start the car, turn on the air conditioner and let the foam cleaning agent circulate in the air conditioning system.
