Smart Accumulator Filtration and Liquid Control to Protect Compressors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressor and compression systems face failures due to contaminants, moisture, and liquid refrigerant entering the compressor, which current solutions, involving separate filter driers and accumulators, are expensive, complex, and not fully effective in preventing damage.
Innovation Solution
The Smart Accumulator with a Centralized Replicable Filtration system, including a filter drier assembly, liquid trigger switch, and safety features like a spring-loaded check valve and bypass safety flap, ensures removal of moisture, contaminants, and prevention of liquid entry by boiling off excess liquid and isolating the intake tube inlet port, thereby protecting the compressor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate filter driers and accumulators are used, then moisture and liquid removal is achieved, but system complexity and cost increase
Solution Approach 1:
The patent combines the filter drier function and accumulator function into a single integrated Smart Accumulator unit. The housing contains both the filtration assembly (with filter drier and strainer mesh) and the liquid accumulation chamber, eliminating the need for separate filter drier and accumulator components while maintaining all necessary functions.
Solution Approach 2:
The Smart Accumulator performs multiple functions within a single device: it filters contaminants through the strainer mesh, removes moisture through the filter drier, accumulates excess liquid refrigerant, and provides heating elements for liquid evaporation. This multi-functional design replaces multiple separate components with one universal unit.
2Reliability
If separate filter driers and accumulators are used, then basic filtration is achieved, but cost increases
Solution Approach 1:
The patent combines the filter drier function and accumulator function into a single integrated Smart Accumulator unit. The housing contains both the filtration assembly (with filter drier and strainer mesh) and the liquid accumulation chamber, eliminating the need for separate filter drier and accumulator components while maintaining all necessary functions.
3Quantity of substance
If conventional accumulators are used, then liquid removal is achieved, but liquid management reliability is insufficient
Solution Approach 1:
The patent incorporates a liquid level float switch that continuously monitors the liquid level in the accumulator chamber. When liquid reaches a predetermined level, the float switch activates heating elements to evaporate the liquid and prevents compressor operation, creating a feedback control system that reliably manages liquid levels and prevents liquid refrigerant from entering the compressor.
Solution Approach 2:
The patent uses phase transition (evaporation) to manage liquid refrigerant. Heating elements heat the liquid refrigerant to convert it from liquid to vapor phase, removing excess liquid from the system. This phase change mechanism provides reliable liquid management by actively converting liquid to gas when liquid levels become excessive.
4Productivity
If the intake tube inlet port is positioned lower, then liquid can be removed more easily, but liquid may enter the compressor
Solution Approach 1:
The patent positions the intake tube inlet port at a specific high location on the housing, creating a localized quality difference in liquid level distribution. The inlet port is positioned above the normal liquid accumulation level, ensuring that while liquid can accumulate in the lower chamber for removal, the gas intake remains in a liquid-free zone, protecting the compressor from liquid entry.

AI summary
The Smart Accumulator Fluid Scrubbing System includes a drying mechanism and filtration system with liquid level control all in one housing to protect compressors or compressor systems from moisture, contaminants, and liquid ingestion. The Smart Accumulator is connected to the compressor or compressor systems inlet. The Smart Accumulator only allow dry, clean gas to enter the compressor and compressor system. The switch in conjunction with the heating elements and compressor circuits prevents the compressor from running, while heating elements boil off excess liquid. The Pressure equalizing port prevent compressor to start at high delta pressure and or reduces extremely high-pressure compressor or system operation that may be detrimental to mechanical failure.
