1.1 Overview
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.

HEATER STRUCTURE AND
WORKING PRINCIPLE
04
PARKING AIR HEATER
11
4.1 Working Principle
After the heater is started, the glow plug plug begins to work,
the fuel pump starts to supply fuel, and the combus-
tion-supporting fan intakes air from outside. Fuel is burned in
the combustion chamber to generate heat, which is taken
away by the aluminum heat exchanger. Internal air driven by
the heat exchange fan passes through the surface of the
heat exchanger to carry the heat to where it is needed. The
exhaust gas is discharged through the exhaust pipe.
