The continuous operation time of a truck's DC parked air conditioning system depends on several factors, including battery capacity, air conditioning settings, and external ambient temperature.
Let's assume our truck's DC parked air conditioning system consumes 1500 watts (W) at maximum cooling mode, and the vehicle's battery capacity is 200 ampere-hours (Ah) at 12 volts (V).
First, we need to convert the battery capacity into watt-hours (Wh):
200 Ah * 12 V = 2400 Wh
Next, we calculate the energy consumed by the air conditioning system per hour (in watt-hours):
1500 W * 1 h = 1500 Wh
Now, we can estimate the time the air conditioning system can operate at maximum cooling mode without starting the vehicle:
2400 Wh / 1500 Wh/h = 1.6 h or 1 hour and 36 minutes
This means that at maximum cooling mode and without starting the vehicle, the air conditioning system can operate for approximately 1 hour and 36 minutes.
However, this is a theoretical calculation. If the air conditioning system does not operate at full power all the time, it may last longer. For example, during nighttime rest, you can activate the economy mode on our air conditioning system. In this mode, the system will automatically reduce the compressor and fan speeds, allowing the continuous operation time to reach 6-8 hours.
Additionally, to protect the battery from over-discharge, our parked air conditioning system is designed with an automatic shut-off feature that will turn off the system when the battery level drops to a certain threshold.
