Is it okay to sleep in a car with the air conditioning on for several hours?

[Deanna]

Sleeping in a car with the air conditioning on for 1 hour is generally fine. Below is extended information about car air conditioning: 1. Car air conditioning operation: The compressor of a car's air conditioning system relies on the engine running to function, while the heating system (hot water) requires the engine to warm up. If you only power on the electrical system without starting the engine, turning on the air conditioning will not produce cooling or heating effects. It will only rapidly drain the car's battery, ultimately damaging it. 2. Function of car air conditioning: Car air conditioning is designed to regulate and control the temperature, humidity, air cleanliness, and airflow within the car cabin to optimal conditions, providing passengers with a comfortable environment and reducing travel fatigue. It also 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. This integrated system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern car air conditioning system internationally.
