Parking Air Conditioner: How long can it run when parked?

Concept 

The calculation of this involves some electrical knowledge. Let me first briefly introduce the basic concepts.

Battery capacity (Ah): The amount of current provided by the battery in 1 hour.

Battery energy (Wh): The total energy that the battery can provide, calculation formula: battery energy = battery capacity * battery voltage.

Power (W): The rate at which work is completed or energy is transferred per unit time. Calculation formula: Power = Current * Voltage.

Therefore, the running time of the parking air conditioner is calculated by: time = (battery capacity * battery voltage) / air conditioner power.

Calculate

Now we start to calculate the usage time of COLKU truck parking air conditioner. Take our best-selling air conditioner G29 as an example, Its input power is 746W. The diesel heavy truck batteries I learned are usually 24v, 200ah. Suppose we take this as an example, (200*24)/746=6.43h. It’s about 6 hours and 43 minutes. This is the running time under the highest load condition. COLKU parking air conditioner is a variable frequency air conditioner with smart energy saving function. Therefore, the actual usage time is much longer than this time.

If you want to ensure 10 hours of use time a night, I have 2 suggestions. Option 1: Reduce the wind speed, select a reasonable air conditioner temperature, reduce the operating power of the air conditioner, and extend the operating time. Option 2, add an battery.
