The HVAC assembly of the present invention has a compact structure, is a common structure for left and right rudders, has good refrigeration and heating effects of the air conditioner, is convenient to disassemble and assemble, and has low maintenance cost, and is suitable for batch application in truck air conditioners.

Description

technical field [0001] The invention belongs to the field of automotive air-conditioning components, in particular to an HVAC assembly with common left and right rudders for truck air conditioners. Background technique [0002] With the development of the truck industry, the requirements for its internal air conditioning system are also getting higher and higher. The air conditioning system refers to the control system including temperature, humidity, air cleanliness and air circulation, which is called HVAC. [0003] In recent years, the number of right-hand drive export vehicles with the steering wheel on the right has increased, while my country is a left-hand drive country with the steering wheel on the left, which brings difficulties to the design of HVAC. [0004] In the existing technology, the HVAC assembly of the traditional truck air conditioner is usually arranged on the left and right under the dashboard according to the design of the car air conditioner. To des...

Problems solved by technology

[0005] In order to adapt to the change of the steering wheel position, it is often necessary to redesign and develop the HVAC assembly suitable for the right-hand drive model through mirror design on the basis of the left-drive model, including the mirror design of the blower, so that the HVAC is designed in this way. The design workload of the assembly is heavy, and the development cycle is long. At the same time, another set of HVAC molds needs to be specially opened for right-hand drive models. The investment in production molds increases, and the design cost and mold cost increase.
