Solution Overview

Problem

Conventional heat pump condensers with direct counter-flow configurations are inefficient due to suboptimal condensation distribution, requiring larger volumes or adjustments in flow, pressure, and cross-section, which complicates system design and reduces performance.

Innovation Solution

Implementing a condenser design where vapor is introduced laterally into the condensation zone, creating a transverse flow direction relative to the liquid flow, enhancing condensation efficiency without increasing the condenser's volume, using features like radial compressors and fillers to redirect vapor and optimize liquid distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If direct counter-flow configuration is used in conventional heat pump condensers, then the condensation process occurs, but the condensation distribution becomes suboptimal requiring larger volumes or adjustments in flow, pressure, and cross-section

Engineering Contradiction:
Improvecondenser volumeVSAvoidcondensation efficiency
Core Design Contradiction:
Volume of stationary objectVSProductivity

Solution Approach 1:

The patent introduces a lateral vapor inlet that feeds vapor into the condensation zone from the side rather than from the top or bottom, creating a transverse flow direction relative to the liquid flow. This dimensional change in vapor introduction enables more uniform condensation distribution throughout the condensation zone without requiring increased condenser volume

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent creates different flow conditions in different regions of the condensation zone by introducing vapor laterally. This results in locally optimized condensation patterns where vapor and liquid flows interact more effectively throughout the volume, improving overall condensation efficiency without increasing the total condenser size

Inventive Principle:
Principle #3Local quality

2Productivity

If larger condenser volume is used to improve condensation distribution, then condensation efficiency improves, but the system becomes more complex and less compact

Engineering Contradiction:
Improvecondensation efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

By changing the vapor introduction direction to lateral flow, the patent achieves improved condensation distribution within the existing condenser geometry, avoiding the need for larger or more complex condenser designs while maintaining high condensation efficiency

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If adjustments in flow, pressure, and cross-section are made to improve condensation distribution, then condensation efficiency improves, but the system design becomes more complex

Engineering Contradiction:
Improvecondensation efficiencyVSAvoidsystem design complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The lateral vapor inlet configuration naturally creates optimized flow patterns and pressure distribution throughout the condensation zone without requiring complex control systems or multiple adjustment mechanisms. The geometric configuration itself achieves the desired condensation distribution

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent changes the flow direction parameter by introducing vapor laterally rather than axially, which fundamentally alters the flow dynamics and pressure distribution within the condenser, achieving improved condensation efficiency through a simple geometric modification rather than complex parameter adjustments

AI summary

A condenser includes a condensation zone (100) for condensing vapor to be condensed in an operating liquid, the condensation zone being formed as a volume zone comprising a top end (100a), a bottom end (100b) and a lateral boundary (100c) between the top end and the bottom end, and a vapor introduction zone (102) extending along the lateral end (100c) of the condensation zone and being configured to feed vapor to be condensed into the condensation zone (100) laterally via the lateral boundary (100c).
