Condensate Trap Chamber Layout for Pressure-Stable Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing condensate traps in heating-cooling systems face challenges with increased furnace vent lengths, leading to large pressure changes and reduced installation flexibility due to their design features, which can cause malfunction or damage from condensation and limit compactness.
Innovation Solution
A condensation trap design featuring an inlet chamber, vent chamber, and outlet chamber with a larger vent volume portion than the inlet chamber, facilitating compactness and efficient drainage under varying pressures, along with a manufacturing method using a mold and injection molding process for production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the trap is designed with multiple input connection points and large internal volume, then the trap can handle condensation effectively, but the minimum size of the trap increases which reduces installation flexibility
Solution Approach 1:
The trap is divided into multiple chambers (inlet chamber, vent chamber, outlet chamber) with distinct functions. Each chamber handles specific aspects of condensation management, allowing the overall system to be compact while maintaining effective condensation handling through functional segmentation rather than requiring a single large volume.
Solution Approach 2:
The chambers are nested within each other in a compact arrangement where the inlet chamber, vent chamber, and outlet chamber are positioned to maximize space utilization. The vent chamber is arranged to be in fluid communication with both inlet and outlet chambers through efficiently positioned passageways, creating a nested configuration that minimizes overall trap size while maintaining all necessary functions.
2Adaptability or versatility
If the furnace vent lengths are increased, then the system can accommodate larger pressure changes, but the trap must operate under conditions where atmospheric pressure undergoes large changes which can cause malfunction or damage
Solution Approach 1:
The vent chamber is pre-configured with a vent opening that maintains continuous communication with the atmosphere, establishing a reference pressure zone before pressure changes occur. This preliminary arrangement allows the trap to accommodate pressure variations from long vent runs by providing a stable reference point that prevents malfunction during pressure transitions.
Solution Approach 2:
The vent chamber acts as an intermediary between the inlet and outlet chambers, buffering pressure changes before they affect the condensation drainage function. By positioning the vent opening to communicate with both chambers through separate passageways, the vent chamber mediates pressure variations and protects the trap's operational stability under large atmospheric pressure changes.

AI summary
A condensation trap comprising an inlet chamber, a vent chamber and an outlet chamber. The inlet chamber is configured to receive condensate fluid through an external opening therein. The vent chamber is in fluid communication with the inlet chamber via a first passageway that includes an internal opening of the inlet chamber. The internal opening is located substantially at an opposite end of the vent chamber as the external opening. The outlet chamber is in fluid communication with the vent chamber via a second passageway that includes an internal opening in a sidewall of the vent chamber and an interior opening in an end of the outlet chamber. The outlet chamber is configured to transmit the condensate fluid through an exterior opening located at an opposite end of the outlet chamber. A vent volume portion is greater than a total volume of an internal space of the inlet chamber.
