Air Conditioner External Make-Up Air Module for Fresh Air Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning systems face limitations in providing adequate make-up air due to costly separate systems and small internal make-up air components within the unit, resulting in limited capacity.
Innovation Solution
An integrated make-up air module is positioned on the exterior of the air conditioner housing, including a motorized damper, fan, air filter, and dehumidifier, which draws outdoor air, filters and dehumidifies it, and supplies it to the indoor environment, enhancing the air conditioning system's capacity and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If make-up air components are placed internal to the air conditioner, then the system is integrated, but the capacity is limited due to limited volume within the air conditioner
Solution Approach 1:
The patent relocates the make-up air module from the internal three-dimensional space to the external surface of the air conditioner housing. This dimensional transition from inside to outside allows the make-up air system to access significantly more space, thereby increasing air handling capacity while maintaining integration with the main unit.
2Quantity of substance
If a separate make-up air system is used, then the capacity can be larger, but the system becomes costly and complex
Solution Approach 1:
The patent combines the make-up air module with the air conditioner housing by positioning it on the exterior surface. This merging approach allows the system to achieve larger capacity similar to separate systems while maintaining the simplicity and cost-effectiveness of an integrated design through shared housing and coordinated operation.
3Volume of moving object
If make-up air components are placed internal to the air conditioner, then the system is compact, but the capacity is limited
Solution Approach 1:
By moving the make-up air module to the exterior of the housing, the system accesses external space rather than being constrained by internal volume. This dimensional shift enables significantly increased air capacity while preserving the compact footprint of the main air conditioner unit.
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
The integrated make-up air module increases the air conditioning system's capacity to provide fresh air, improving indoor air quality and reducing humidity, while being cost-effective and space-efficient by eliminating the need for separate make-up air systems.
