Can the Parking Air Conditioner Be Used While Driving?

Modifying the original vehicle compressor is definitely not feasible, as the original compressor is driven by the engine via a pulley. When the engine is turned off, the air conditioner cannot function. Below is an introduction to parking air conditioners: 1. Introduction: A parking air conditioner is an in-vehicle air conditioning unit. It uses the vehicle's DC battery power (12V/24V/36V) to sustain operation while parked or resting, regulating and controlling parameters such as temperature, humidity, and airflow inside the vehicle to fully meet the comfort and cooling needs of truck drivers. 2. Low Voltage Protection: Since the parking air conditioner is directly connected to the truck's battery, many drivers worry about the dilemma of enjoying the air conditioner while parked but being unable to start the engine later. Therefore, the "low voltage cutoff protection function" of the parking air conditioner is particularly important.
You cannot use the parking air conditioning while driving because it is not designed for use during operation. I often encounter this issue during long-distance transportation—the parking AC relies on the 12V battery and is suitable for use during rest stops. However, if you turn it on while driving, even though the engine is running, it draws too much power, and the alternator cannot recharge the battery fast enough. This quickly drains the battery, leading to engine stalling, which is extremely dangerous. Once, on a hot day, I accidentally left it on the entire trip, and the battery died, leaving me stranded on the road until I called for assistance. The correct approach is to use the vehicle's built-in main air conditioning system while driving, setting it to automatic mode for efficiency and safety. Switch to the parking AC only after stopping. This not only saves fuel but also protects the electrical system. I recommend checking the manual to confirm the proper settings.
