Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window type air conditioners suffer from reduced cooling efficiency due to heat generated by control components being introduced into the indoor space and high noise and power consumption caused by constant speed compressors.
Innovation Solution
The design includes a compressor and control components capable of inverter control, with control components disposed in an air passage to dissipate heat easily and a reactor assembly stably supported to prevent heat transfer to the indoor side, using a compact passage configuration to facilitate smooth airflow and efficient cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control components are installed at the indoor side, then control function is achieved, but heat generated by control components is introduced into the indoor space deteriorating cooling efficiency
Solution Approach 1:
The control components (control box and reactor assembly) are extracted from the indoor side and relocated to the outdoor side, specifically disposed in the outdoor-side air passage. This separation removes the heat-generating control components from the indoor space, preventing heat transfer to the indoor area and maintaining cooling efficiency while preserving full control functionality.
2Device complexity
If a constant speed compressor is used, then simple structure is achieved, but noise and power consumption increase
Solution Approach 1:
The compressor is replaced with an inverter-controlled compressor that can dynamically adjust its operating speed according to actual cooling or heating demands. This dynamic control enables the compressor to operate at optimal speeds, reducing noise levels and power consumption while maintaining system performance, eliminating the need for high-speed operation required by constant speed compressors.
3Loss of energy
If control components are disposed in the outdoor-side air passage, then heat dissipation is improved and heat does not transfer to indoor space, but space arrangement becomes more complex
Solution Approach 1:
The control components (control box and reactor assembly) are merged into a single integrated unit disposed together in the outdoor-side air passage. This consolidation simplifies the overall space arrangement by treating control components as one assembly rather than separate elements, while still achieving the dual benefits of effective heat dissipation through the outdoor air flow and prevention of heat transfer to the indoor space.
4Volume of stationary object
If a compact passage configuration is used, then spatial utilization is improved, but airflow smoothness may be compromised
Solution Approach 1:
The air passage is configured with optimized three-dimensional spatial arrangement that allows compact integration of components while maintaining smooth airflow paths. The outdoor-side and indoor-side air passages are designed with appropriate dimensions and orientations in multiple directions, enabling compact spatial utilization without creating turbulent or restricted airflow, thus achieving both compactness and airflow smoothness.
