Which type of Auxiliary Power Unit is best?
With diesel-powered APUs, there’s virtually unlimited power available to heat and cool as long as fuel is in the APU. Battery-powered APUs (Electric) have the advantage of no noise, but have limited run times. The average [battery-powered] APU will provide up to 10-12 hours of air conditioning capacity and typically longer than that for heating. Long-haul applications are best suited for diesel-powered APUs, until battery technology can meet heavier power requirements.
