When the air conditioner is turned on in the car, can the trunk feel the airflow?

Because there is a certain distance between the air conditioning vents and the trunk, and there is usually a partition between the trunk and the front seats, turning on the air conditioner inside the car does not significantly affect the trunk. Here is some information about car air conditioning: 1. Car Air Conditioning: The car air conditioning system (air-conditioning-device), commonly referred to as car AC, is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to an optimal state. It provides a comfortable environment for passengers, reduces travel fatigue, and creates favorable working conditions for the driver, playing a crucial role in ensuring safe driving. Generally, it includes cooling devices, heating devices, and ventilation systems. 2. AC Layout: Different types of air conditioning systems have varying layouts. Currently, integrated heating and cooling systems are widely used in passenger cars. The layout involves assembling components such as the evaporator, heater core, centrifugal blower, and control mechanisms into a single unit, known as the air conditioning assembly.
As an automotive enthusiast who frequently tinkers with various vehicle systems, I'm quite familiar with how car air conditioning works. The car's AC delivers cooled or heated air into the cabin through ventilation outlets on the dashboard and rear seats, primarily targeting passenger comfort zones. The trunk is an independently sealed compartment that typically doesn't feature dedicated air vents, so when you turn on the AC, the trunk receives virtually no airflow. Unless it's an older station wagon or SUV with the rear hatch open, air simply can't circulate there. This design prioritizes energy efficiency and safety - preventing moisture accumulation or dust buildup on stored items, while also avoiding potential hazards like children or pets accidentally entering. For cooling items in the trunk, it's better to place them on the rear floorboard or use insulated bags. I recommend regularly checking the cabin air filter to maintain proper airflow distribution throughout the vehicle, but don't expect the trunk to benefit from AC cooling.
I've been driving my own car for several years and often take my family out during the summer. When the air conditioning is on, you can clearly feel the comfortable breeze inside the cabin, but items in the trunk, like luggage or food, hardly cool down. I remember once during a long trip, I deliberately placed a bottle of water in the trunk, only to find it still lukewarm when we stopped, unlike the coolness inside the cabin. This shows that the car's air conditioning vents are only installed near the front dashboard and rear seats, while the trunk is an isolated space without any air ducts for ventilation. It mainly relies on door gaps or slight air infiltration to slowly balance the temperature, but this is far from direct airflow. So, if you have sensitive items in the trunk, it's advisable to pre-cool them or briefly open the trunk lid during the drive to let the air circulate. Overall, this design makes the air conditioning more efficient in serving the driver and passengers.
