Parking air heaters can be used in almost any vehicle or space that need warmth, like truck cabs, buses, RVs, boats, tents or motor homes, etc. Being maneuverable and flexible, parking heaters are popular among drivers and campers. Parking heaters employed a simple way to warm your trip, and here’s how a diesel air heater works.
First, you need to install the parking air heaters according to the manufacturer’s instructions. After installing it in the right way, you can then turn on the diesel air heater.
As soon as you turn on the parking air heater, its control system will run a diagnostic test to ensure that all components are in perfect operating condition. This system controls and executes various commands depending on the received signal. When the parking air heater is in good condition, the engine fan will start spinning. This introduces high-speed air into the system.
Air and fuel must occur in order to generate heat. By the way, the idea here is not much different from the combustion of the internal engine of a truck.
The engine speed will slow down as the spark plugs engage. This preheats the combustion tube.
The fuel pump begins to deliver fuel to the parking air heater system. The fuel can come from the vehicle’s tank or an independent mini fuel tank. At the same time, the glow plug receives electric current which it uses to ignite the fuel after atomization. Meanwhile, the combustion blower continues to pump air into the chamber. When the spark plug ignites the air-fuel mixture, heat and flame monitoring sensors detect and monitor every step in the combustion chamber. Sufficient fuel and air must be available. At this stage, the heater system will control the flow of air, fuel and combustion in the system. So, both air and fuel will continue to burn and the exhaust leaves the system.
Cold air comes in and warm air comes out of the diesel air heater. You may wonder what was happened inside the parking air heater. So when the parking heater has enough heat, it heats (heat transfers) the air flowing through the heat exchanger. Cold air then flows into the car’s heat exchanger system, from which heat is transferred to the interior space or your cab. That means it uses the car’s ventilation system. Depending on the design of the fuel-operated heater, hot air will flow into the engine. You can warm the engine and start easily even in cold weather. Spent air flows back from the engine to the parking air heater and this cycle continues.
When the car or tent has reached the desired temperature, you can turn off the fuel heater. When the system receives a signal to stop the heater, the fuel pump will stop working. This cuts off the fuel supply. At the same time, the spark plugs will operate for a while to burn all the remaining fuel. High-speed motors, on the other hand, cool the heater and blow off burned carbon and residues from the heater. The fan speed will slow down until it stops later. As you can see, the operating principle of the parking heater is straightforward.
