Air conditioning unit condensate removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner units face challenges in managing condensate accumulation, leading to undesirable effects when the rate of condensate removal is insufficient.
Innovation Solution
The implementation of a method and system for detecting condensate levels in the base pan of an air conditioner unit, activating a fan-only mode, and potentially slowing or stopping the compressor when predetermined threshold levels are exceeded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If active condensate removal mechanisms are employed, then condensate removal rate is improved, but device complexity increases
Solution Approach 1:
The system uses a level sensor to automatically detect condensate levels and trigger fan-only mode operation, eliminating the need for complex mechanical pumps or manual intervention. The air conditioner self-monitors and self-regulates condensate removal based on detected levels.
Solution Approach 2:
The system changes the operational parameters of the air conditioner by switching to fan-only mode (disabling the compressor) when condensate reaches a threshold level. This parameter change allows increased air flow for evaporation without adding mechanical removal complexity.
2Productivity
If compressor operation continues at high capacity, then cooling productivity is improved, but condensate accumulation increases
Solution Approach 1:
The level sensor provides continuous feedback on condensate volume in the base pan. When the feedback indicates high condensate levels, the controller automatically reduces cooling capacity by switching to fan-only mode, creating a closed-loop control system that balances cooling needs with condensate management.
Solution Approach 2:
The system dynamically adjusts its operational mode based on real-time condensate conditions. The compressor operates at full capacity when condensate levels are low, but automatically reduces capacity when levels rise, creating a dynamic response to changing operational conditions.
3Device complexity
If condensate evaporation is relied upon, then device complexity is reduced, but condensate removal rate becomes insufficient
Solution Approach 1:
The level sensor detects condensate accumulation before it becomes a problem, and the system proactively switches to fan-only mode to accelerate evaporation. This preliminary action prevents overflow conditions while maintaining system simplicity.

AI summary
An air conditioner unit includes an indoor heat exchanger, an outdoor heat exchanger, and a base pan below the indoor heat exchanger and the outdoor heat exchanger. Methods of operating the air conditioner unit may include, or a controller of the air conditioner unit may be configured for, detecting, with a level sensor, a level of condensate in the base pan above a predetermined threshold level and operating the air conditioner unit in a fan only mode in response to detecting the level of condensate above the predetermined threshold level.
