Can the car be driven if the air conditioning doesn't start?

[VanSavannah]

Vehicle's air conditioning cannot operate when the car isn't started, as the compressor will lack power to function. Below is relevant information about automotive air conditioning: Working principle of automotive air conditioning: The working principle includes compression process, heat dissipation process, throttling process, and heat absorption process. Similar to household air conditioners, refrigerant continuously transforms from liquid to gaseous state, thereby lowering the air temperature around the evaporator, which then enters the vehicle through the air delivery system. Precautions for using automotive air conditioning: Avoid setting temperature too low; control air outlet direction; don't use for extended periods; appropriately activate high airflow; turn off AC during low-speed driving.
