Vehicle, method and system for drying evaporator of vehicle air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for drying vehicle air conditioner evaporators are inefficient and often compromise indoor air quality, leading to user discomfort and poor user experience due to the discharge of hot air into the cabin during the drying process.
Innovation Solution
A method involving closing the air duct after cooling stops, using the heating core and fan to generate hot air that circulates over the evaporator core to evaporate condensed water, and directly venting the hot and humid air to the exterior, thereby accelerating drying while maintaining indoor air quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the air outlet mode is set to foot blowing mode during evaporator drying, then the drying efficiency is improved, but the temperature in the vehicle cabin rapidly rises and air quality deteriorates
Solution Approach 1:
The air outlet is segmented into two independent channels: one channel directs hot air to the evaporator for drying, while the other channel maintains normal cabin air supply. This segmentation allows the drying function to be performed without discharging hot air into the cabin, thus maintaining cabin comfort and air quality while achieving effective evaporator drying.
2Productivity
If hot air is discharged into the vehicle cabin during air circulation, then the evaporator drying is accelerated, but user comfort is reduced and user experience deteriorates
Solution Approach 1:
The harmful hot air that would normally be discharged into the cabin is extracted and redirected through a separate exhaust channel to the external environment. This extraction ensures that the hot air used for drying does not enter the cabin space, thereby maintaining user comfort while achieving the drying objective.
3Reliability
If existing drying methods are used, then the evaporator can be dried, but energy consumption increases and drying efficiency remains low
Solution Approach 1:
The heating function and drying function are merged into a single integrated process. The heating core generates hot air that is simultaneously used for both cabin heating (when needed) and evaporator drying, eliminating the need for separate drying operations and reducing overall energy consumption while maintaining drying effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances drying efficiency with reduced energy consumption, prevents hot air from entering the cabin, and maintains indoor comfort, resulting in a high-efficiency, low-energy drying process for the evaporator.
Implementation Method 1
hot air capable of circulating is generated in the air duct by means of the heating core and the fan, and during circulation, the hot air passes by the surface of the evaporator core and carries away condensed water precipitated on a surface of the evaporator core for conversion into hot and humid air
Implementation Method 2
hot air capable of circulating is generated in the air duct by means of the heating core and the fan
