Automobile air conditioning system temperature control curve optimization structure

Abstract

The invention belongs to the field of automobiles, and relates to an automobile air conditioning system temperature control curve optimization structure which comprises a middle shell, a left shell and a right shell, and a face blowing air door, a foot blowing air door and a defrosting air door which are used for controlling face blowing, foot blowing and defrosting respectively are arranged in acavity formed by the middle shell, the left shell and the right shell. The structure further comprises an air mixing door which comprises an upper mixing air door and a lower mixing air door which areindependently arranged; the upper mixing air door comprises an upper-layer cold runner and an upper-layer hot runner, and the lower mixing air door comprises a lower-layer hot runner and a lower-layer cold runner. According to the invention, the linearity can be better optimized, the temperature can be orderly and quantitatively increased, the jittering condition is avoided, the temperature difference between the upper, lower, left, right, front and back parts can be better changed, the temperature difference required by different parts of passengers is effectively met, the comfort of a passenger compartment is better controlled, and vehicle models with more modes can be efficiently met.

Description

technical field [0001] The invention belongs to the field of automobile air conditioners, and relates to an optimization structure for temperature control curves of an automobile air conditioner system. Background technique [0002] In the traditional automobile air conditioning box technology, the cold and hot mixed air inside the air conditioning box can only be adjusted by the opening of the mixing damper. The structure is relatively limited, and the hot and cold air is easy to form a hedge and mix unevenly; , resulting in a large temperature difference between the upper and lower sides, and the air outlet on the blowing surface has less heat loss than the air outlet on the foot and the rear blowing surface, resulting in a higher temperature on the blowing surface than the foot and rear blowing surfaces; in different modes, the mixed air position is easy to form a vortex, convection The field has a great influence; when the air conditioner is in the foot blowing defrostin...

Problems solved by technology

[0002] In the traditional automobile air conditioning box technology, the cold and hot mixed air inside the air conditioning box can only be adjusted by the opening of the mixing damper. The structure is relatively limited, and the hot and cold air is easy to form a hedge and mix unevenly; , resulting in a large temperature difference between the upper and lower sides, and the air outlet on the blowing surface has less heat loss than the air outlet on the foot and the rear blowing surface, resulting in a higher temperature on the blowing surface than the foot and rear blowing surfaces; in different modes, the mixed air position is easy to form a vortex, convection The field has a great influence; when the air conditioner is in the foot blowing defrosting mode, the large temperature difference will easily cause low defogging and defrosting efficiency

Generally speaking, the comfort in the passenger compartment is not well controlled, and there are potential safety hazards for driving
