Heat Pump Condenser Partition for Foreign Gas Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat pumps operating at low pressures face inefficiencies due to foreign gases that do not condense, leading to energy loss and maintenance challenges, as continuous evacuation of working vapor results in unwanted energy release and liquid level depletion.
Innovation Solution
A heat pump design incorporating a condenser with a foreign gas collection space and partition wall, where the condensation surface is colder than the working vapor, allowing foreign gases to accumulate and be discharged, while maintaining working vapor within the system, reducing the need for frequent liquid refilling and minimizing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous evacuation is performed to remove foreign gases, then foreign gas concentration is reduced, but working vapor is lost and energy is wasted
Solution Approach 1:
The condenser is divided into two distinct chambers: a first chamber for condensing working vapor and a second chamber for collecting foreign gases. The partition wall separates these chambers, allowing foreign gases to be removed from the second chamber without affecting the working vapor condensation process in the first chamber. This segmentation enables selective removal of foreign gases while retaining working vapor, thus reducing energy loss.
Solution Approach 2:
Foreign gases are extracted from the system through the second chamber, which is specifically designed to accumulate and discharge foreign gases. The foreign gas discharge device removes foreign gases from the second chamber without requiring continuous evacuation of the entire condenser, thereby preventing loss of working vapor and associated energy waste.
2Productivity
If foreign gases accumulate in the condenser, then system pressure increases and efficiency decreases, but continuous evacuation causes working vapor loss
Solution Approach 1:
The condenser is segmented into a first chamber for working vapor condensation and a second chamber for foreign gas collection. This allows foreign gases to accumulate in the second chamber without affecting the condensation efficiency in the first chamber, while enabling periodic removal of foreign gases without losing working vapor.
Solution Approach 2:
The partition wall acts as an intermediary structure that separates the working vapor condensation process from the foreign gas accumulation and removal process. This mediator allows foreign gases to be discharged from the second chamber without interfering with the working vapor in the first chamber, preventing working vapor loss during foreign gas removal.
3Ease of manufacture
If the condenser operates without foreign gas removal, then system maintenance is simplified, but energy loss increases due to reduced condensation efficiency
Solution Approach 1:
The condenser is divided into functional segments: a first chamber optimized for working vapor condensation and a second chamber for foreign gas collection. This segmentation allows the system to maintain high condensation efficiency by keeping foreign gases separated in the second chamber, while the simple discharge mechanism maintains ease of maintenance.
Solution Approach 2:
The foreign gas discharge device enables periodic self-service removal of foreign gases from the second chamber without requiring complex continuous evacuation systems. This maintains condensation efficiency in the first chamber while keeping the overall system simple to maintain.
