Biocide Release Control for Air Conditioner Condensate Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensate drain pipes in air conditioning systems are prone to blockages due to biotic growth, such as algae and fungus, which can lead to water damage, as existing biocide dispensing methods lack a controlled and efficient mechanism for releasing biocides into condensation lines.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biocide is continuously dispensed into the condensation line, then biological buildup is prevented, but the device complexity and manufacturing cost increase
Solution Approach 1:
The device employs periodic action by using a vacuum pump to create intermittent vacuum cycles that draw biocide through the condensation line at specific intervals rather than continuous dispensing. The controller activates the pump periodically to maintain biocide flow, simplifying the mechanical structure while ensuring reliable biological buildup prevention.
Solution Approach 2:
The system utilizes the natural vacuum pressure differential created by the HVAC system's condensate pump to drive biocide flow through the line. The biocide container is positioned to allow vacuum-powered dispensing without complex mechanical actuators, reducing device complexity while maintaining effectiveness.
2Manufacturing precision
If a complex controlled dispensing mechanism is used, then biocide release is precisely regulated, but the device becomes more expensive to manufacture and maintain
Solution Approach 1:
The invention replaces complex mechanical dispensing mechanisms with a vacuum-driven system controlled by a simple timer or pressure sensor. The vacuum pump creates pressure differentials that automatically regulate biocide flow rates, eliminating the need for complex mechanical valves, pumps, or electronic control systems while maintaining precise dispensing control.
Solution Approach 2:
The system controls biocide dispensing by changing vacuum pressure parameters rather than using complex mechanical flow control. By adjusting vacuum level and duration through a simple controller, the device achieves precise biocide release regulation with minimal moving parts, reducing manufacturing complexity and maintenance requirements.
3Object-affected harmful factors
If existing biocide dispensing methods are used, then some biological protection is provided, but blockages still occur due to insufficient controlled release
Solution Approach 1:
The device applies preliminary action by continuously maintaining a supply of biocide in the condensation line through vacuum-driven flow. This ensures biocide is present before biological growth can establish, preventing blockages proactively rather than reacting to existing buildup. The system primers the line with biocide continuously or at frequent intervals.
Solution Approach 2:
The invention ensures continuity of useful action by maintaining constant or frequent biocide presence in the condensation line through vacuum-powered flow. This continuous exposure prevents biological growth from establishing and causing blockages, providing reliable protection unlike intermittent dispensing methods that allow growth cycles to complete.

AI summary
A time release biocide dispensing device for controllably dispensing biocide into a condensation line of an air conditioner at predetermined concentrations and volumes over a duration. The device utilizes principles of pressure equilibrium and material resistance to dispense a regulated and steady flow of the biocide into the line. The device utilizes a controller, a pump, a container, a fluid tube, and a coupling member. The device is configured to easily attach to the line and facilitate setting of the controller, such that minimal tools and expertise are needed for operation. A container attaches to the line and holds a biocide and a volume having a vacuum. A pump forces a fluid into the vacuum to disturb the equilibrium, and thus partially force the biocide into the line. A resistance member restricts the flow to drops to further regulate the flow of the biocide into the line.
