What is the vent under the seat?
1 Answers
The vent under the seat is an air conditioning vent. Below is the relevant introduction: 1. Principle of car air conditioning: Most car air conditioning heating systems rely on waste heat from the engine. The AC control button in the car controls the air conditioning compressor. Since cars do not have a four-way valve like household air conditioners, they cannot provide heating in the same way. Therefore, turning on the compressor while using the heater in winter serves only one purpose: dehumidification. 2. Power consumption: Cooling consumes more power, while heating consumes relatively less. After the engine coolant reaches operating temperature, turning on the heater has minimal impact on fuel consumption, as the heating system utilizes waste heat from the engine.
