Window Air Conditioner Vacuum Chamber for Noise and Heat Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window-type air-conditioning apparatuses suffer from high noise levels due to internal component vibrations and energy inefficiency caused by heat exchange between cold and hot parts, leading to discomfort and increased energy consumption.
Innovation Solution
An air-conditioning apparatus with a vacuum chamber positioned between the evaporator and condenser portions acts as an acoustic and thermal barrier, reducing noise transmission and heat exchange, featuring a cabinet design with a cross-sectional area equivalent to the vacuum chamber's area, and comprising supports and fins for structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If window-type air-conditioning apparatuses are designed with compact single-cabinet structures, then installation ease and cost are improved, but noise transmission to internal environment increases due to vibration transmission
Solution Approach 1:
The cabinet is divided into multiple compartments separated by partitions, with each compartment housing specific components (compressor, condenser, evaporator, ventilator). This segmentation isolates vibration sources from the internal environment and enables targeted vibration control measures in each compartment.
Solution Approach 2:
Vibration isolation elements (elastomeric materials, springs, rubber buffers) are introduced as intermediary components between vibrating parts (compressor, condenser, evaporator) and the cabinet structure. These intermediaries absorb and dampen vibrations, preventing their transmission to the cabinet and internal environment.
2Volume of moving object
If evaporator and condenser are positioned in close proximity within the cabinet, then device compactness is improved, but heat exchange between cold and hot parts increases causing energy loss
Solution Approach 1:
The cabinet is divided into a hot compartment (housing condenser and compressor) and a cold compartment (housing evaporator and ventilator) separated by thermal insulation partitions. This segmentation maintains compact overall dimensions while preventing direct thermal contact between hot and cold components, thereby reducing parasitic heat exchange.
Solution Approach 2:
Thermal insulation materials are introduced as intermediary layers between the hot compartment and cold compartment. These insulation layers act as thermal barriers that prevent heat transfer from the condenser/compressor region to the evaporator/ventilator region, reducing energy loss from unwanted heat exchange.
3Object-generated harmful factors
If vibration isolation measures are implemented for internal components, then noise transmission is reduced, but device complexity increases
Solution Approach 1:
The cabinet is segmented into vibration-isolated compartments with partitions that structurally separate vibration sources from the cabinet shell. This segmentation approach provides effective vibration isolation through the cabinet structure itself, reducing the need for additional complex isolation mechanisms.
Solution Approach 2:
Vibration isolation elements (elastomeric materials, springs, rubber buffers) serve as simple intermediary components that are easily integrated into the existing cabinet structure. These elements provide effective vibration damping without requiring complex mechanical systems or extensive structural modifications.
