1.1 Overview
Fig. 1
The main unit of this parking air heater (the 
"heater") is a small, microprocessor-controlled, 
fuel-burning furnace. Its heat exchanger is located 
in a hood-shaped case with a separate air 
passage. Cold air is sucked into this air passage by 
the fan, and hot air blown out, forming a heating 
system independent of the vehicle's original 
heating system. In this way, a vehicle’s cab or 
passenger compartment can be heated whether 
or not the engine is running.A schematic diagram 
is shown in Fig. 1.
