Condenser Coil Cleaning Bag for Debris Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for cleaning air conditioning condenser coils using compressed air disperse debris into the air, causing pollution due to lack of containment.
Innovation Solution
A flexible, adjustable containment bag with air and vacuum holes is placed over the condenser coil subassembly to enclose it during cleaning, using compressed air to loosen debris and simultaneous vacuum to collect it, preventing airborne dispersal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compressed air is directed against the condenser coil subassembly to loosen debris, then the cleaning effectiveness is improved, but airborne pollution is generated due to lack of containment
Solution Approach 1:
A flexible containment bag is introduced as an intermediary between the condenser coil subassembly and the cleaning environment. The bag encloses the coil assembly, allowing compressed air to be directed against the coils to loosen debris while preventing the debris from dispersing into the atmosphere. The bag acts as a mediator that contains the harmful effect (debris dispersal) while preserving the useful effect (cleaning effectiveness).
Solution Approach 2:
The containment system uses a flexible bag made of thin film material that can conform to the shape of the condenser coil subassembly. This flexible shell encloses the coil assembly, creating a contained environment where debris can be loosened and collected without escaping into the surrounding air, thus eliminating airborne pollution while maintaining cleaning effectiveness.
2Object-generated harmful factors
If a containment bag is placed over the condenser coil subassembly to prevent debris dispersal, then airborne pollution is reduced, but the device complexity increases
Solution Approach 1:
The invention uses a simple flexible bag made of thin film material as the containment structure. This flexible shell can be easily placed over the condenser coil subassembly and secured with a drawstring or elastic closure. The simplicity of the flexible shell design minimizes device complexity while effectively preventing debris dispersal into the atmosphere.
Solution Approach 2:
The containment bag is designed as a simple, inexpensive, and potentially disposable component. Rather than creating a complex reusable containment system, the invention employs a straightforward bag structure that can be easily manufactured and replaced if needed, thereby reducing overall device complexity and cost.
3Stability of the object's composition
If the containment bag covers the entire air conditioner including compressor and electrical components, then complete enclosure is achieved, but the ease of operation decreases due to risk of damage to other components
Solution Approach 1:
The containment system is segmented to cover only the condenser coil subassembly rather than the entire air conditioner unit. The flexible bag is designed to fit specifically over the coil assembly, which can be separated or accessed independently from the compressor and electrical components. This segmentation allows complete enclosure of the cleaning area while avoiding exposure of sensitive components to water or electrical hazards.
Solution Approach 2:
The containment bag provides localized enclosure specifically where needed - over the condenser coil subassembly during cleaning operations. The bag is positioned and secured to cover only the coil area, leaving the compressor, electrical wiring, and other sensitive components exposed and accessible. This local quality approach ensures operational safety by protecting only the area subject to water spray while maintaining ease of operation.

Function Achieved in This Case
Effectively cleans condenser coils without dispersing debris into the atmosphere, ensuring a cleaner environment and efficient operation.
Implementation Method 1
compressed air is then supplied through a hose 25 and through one ('inlet') hole 23 into the interior of the enclosed area containing subassembly 11 to vigorously impact the condenser coils in that assembly and to thereby loosen and remove debris from the surface of the coils
Implementation Method 2
vacuum air is supplied through another hose 26 through the other ('outlet') hole 24 to suction off and thereby remove the thus loosened and airborne, but confined, debris from within the enclosed area covered by the bag

AI summary
The invention relates to a method of cleaning the condenser coil subassembly of an air conditioning apparatus and a bag apparatus for achieving that result. The invention envisions placing a flexible bag construction over and generally around such subassembly, but not over or around the subassembly containing the other components of the air conditioner. This bag has an adjustable mouth portion that will fit over the condenser coil subassembly and also has respective hole means to allow the entry of compressed air and exit of vacuum air, respectively, to and from the enclosed area surrounding the condenser coil subassembly. When the bag is appropriately in place over the subassembly to be cleaned, compressed air is supplied to the enclosed area to loosen and remove debris from the coils while vacuum air is also supplied to remove the debris from the enclosed area to thereby resulting in a cleaning of the condenser coil subassembly without contaminating the area outside the bag.
