Low-noise air conditioner and viewing shelter

Solution Overview

Problem

Integrated air conditioners generate significant operational noise due to the integration of the condenser, evaporator, and compressor into a single unit, negatively impacting user experience.

Innovation Solution

A low-noise air conditioner design with a housing divided into an upper cavity and a lower cavity, where the noise-generating heat exchange module is isolated in the upper cavity, and indoor air pathways are configured through first and second channels in the lower cavity to reduce noise and enhance sound insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the condenser, evaporator, and compressor are integrated into a single unit, then the device complexity is reduced and size is minimized, but operational noise increases significantly

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

The housing is divided into an upper cavity and a lower cavity through a partition. The heat exchange module (containing compressor, condenser, and evaporator) is placed in the upper cavity, while the lower cavity contains air channels for indoor air circulation. This segmentation physically separates the noise-generating components from the air handling pathways, reducing noise transmission to the indoor environment while maintaining the integrated design benefits.

Inventive Principle:
Principle #1Segmentation

2Object-generated harmful factors

If the heat exchange module is isolated in a separate cavity, then noise reduction is improved, but the device complexity increases due to additional partitions and channels

Engineering Contradiction:
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The lower cavity serves multiple functions: it acts as a noise barrier by separating indoor air pathways from the heat exchange module, provides structural support for the air channels, and facilitates heat exchange by guiding processed air into the indoor space. The partition simultaneously defines cavity boundaries and serves as a mounting surface for components, reducing the need for additional structural elements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the air conditioner is designed for hidden mounting with reduced size, then the adaptability is improved, but the noise isolation effectiveness may be compromised

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The partition is positioned vertically to divide the housing into upper and lower cavities, creating a layered three-dimensional structure. This vertical dimensionality allows the heat exchange module to be compactly arranged in the upper portion while the lower portion accommodates air channels that extend to the housing boundaries, enabling hidden mounting in ceiling or wall spaces while maintaining effective noise isolation through the vertical separation.

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