Truck air conditioners are made up of many parts that work together to achieve the cooling and heating functions of the air conditioning system. The most important truck AC parts are the compressor, condenser, evaporator, condensing fan, evaporating fan.
In this article, I will focus on one of them, the fan. It may look simple but it is Africa important for the air conditioning system.
The types of truck AC parts fans are classified into brushed and brushless fans. They each have their own characteristics in terms of structure, longevity and performance.
A brushed fan is a power unit used to generate airflow in an air conditioning system. Brushed fans achieve current commutation through their internal stator, rotor, brushes and commutator co-ordination. The change of current direction generates a magnetic field, which drives the fan to rotate.
Characteristics of brushed fans: Simple process, low cost. Common problems with brushed fans are brush wear and commutator friction. This results in a relatively short service life and can be noisy.
Brushless fans use a more advanced design. The interaction between the magnetic field generated by the stator coils and the rotor's permanent magnets drives its rotation. No physical brushes are required for commutation.
Features of brushless fans: Brushless fans have the advantages of high energy efficiency ratio, low noise, high speed and long service life. Brushless fans operate more smoothly and reliably due to the absence of problems such as brush wear and brush sparking. At the same time, brushless fans provide a wider range of rotational speeds and accurately control wind speed, allowing them to adapt to a broader range of usage scenarios. They are usually used in high-end truck air conditioners, etc.
To sum up, High quality truck AC parts are the foundation of high-end truck air conditioners. Never neglect it.
Truck air conditioner fans classify further into condensing fans and evaporative fans, determined by their installation location and function.
Condensing fans are installed inside the condenser. The function of the condensing fan is to drive the fan to exhaust the hot air from the condenser to the outside of the vehicle, completing the release of heat and making the refrigerant liquefy faster.
The evaporator fan, on the other hand, is installed inside the evaporator. The function of the evaporator fan is to draw the air inside the vehicle into the evaporator by driving the fan, so that it can exchange heat with the refrigerant in the evaporator, thus cooling the air inside the vehicle and providing a comfortable driving environment for passengers.
The truck air conditioner 20ERT, both the evaporation fan and the condensation fan are brushless fans. This choice makes it last much longer. Of course, there are many more high quality truck AC parts that 20ERT uses. For example, the high-quality and very stylish black case, etc. The fan is one of the most fragile parts in a truck air conditioner, so you must pay attention to this detail when picking a truck air conditioner supplier.
Cooling Capacity: 2.5KW /8525BTU
Advantages: Competitive Price & Higher Quality
Color: black and white optional
Voltage: DC12 V/24 V
Application: Truck AC, Van AC, Tractor AC, Heavy Equipment AC, Caravan AC, RV AC, etc.
In addition, there are two types of fans for truck air conditioners: condensing fans and evaporative fans. Some truck air conditioner manufacturers mix them up, such as using a brushless fan for the condensing fan and a brushed fan for the evaporating fan. If you don't ask, you may mistake them both for brushless fans. It is heartily recommended not to take the easy option of choosing certain truck air conditioner manufacturers just because they have low prices. Please make sure to consider it in conjunction with the reputation, after-sales level and technical strength.
