Solution Overview
Problem
Existing ventilation systems for air conditioning in buildings have large space requirements and low energy efficiency due to the need for powerful fans and heat exchangers.
Innovation Solution
The system relocates the turbomachine and heat exchanger components to reduce pipe length, incorporates a temperature body as a radiator to enhance airflow, and features a pivotable housing for improved airflow control and maintenance access, allowing for reduced fan power and increased efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If powerful fans and heat exchangers are used to achieve required ventilation performance, then ventilation efficiency is improved, but space requirements increase and device complexity increases
Solution Approach 1:
The housing is made pivotable around a horizontal axis, allowing it to be positioned in different orientations. This dynamic positioning enables the system to adapt to different installation scenarios and space constraints, achieving required ventilation performance without requiring excessively large fixed components
Solution Approach 2:
The pivotable housing introduces a new degree of freedom (rotational movement around horizontal axis) to the system. This allows the air outlet to direct airflow in different directions, effectively utilizing three-dimensional space for ventilation distribution without increasing the physical footprint of the device
2Productivity
If powerful fans and heat exchangers are used to achieve required ventilation performance, then ventilation efficiency is improved, but energy consumption increases
Solution Approach 1:
The pivotable housing allows optimization of airflow direction and distribution, improving ventilation efficiency without requiring excessive fan power. By adjusting the housing position, the system can achieve better airflow patterns that reduce energy consumption while maintaining required ventilation performance
3Stability of the object's composition
If the housing is fixed in position to ensure structural stability, then structural stability is improved, but maintenance access to heat exchanger deteriorates
Solution Approach 1:
The housing is designed to be pivotable around a horizontal axis rather than completely fixed. This allows the housing to be rotated into a maintenance position where the air outlet faces downward, providing easy access to the heat exchanger for cleaning and servicing, while returning to a stable operational position for normal use
Solution Approach 2:
The housing alternates between operational position (for ventilation) and maintenance position (for servicing). This periodic movement between states allows the system to maintain structural stability during operation while providing periodic access for maintenance, resolving the contradiction between fixed stability and maintenance accessibility
