Ducted type air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ducted type air conditioners suffer from low heat exchange efficiency due to the influence of the water-receiving disk on airflow, which is not adequately addressed in existing designs.
Innovation Solution
The air-absorbing and exhaust openings of the fan are inclined upwards relative to the horizontal direction to minimize the impact of the water-receiving disk on airflow, with inclination angles ranging from 0° to 12° and 0° to 15° respectively, ensuring unobstructed air intake and discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the water-receiving disk is arranged between the fan and air opening to receive condensed water, then water drainage function is improved, but airflow obstruction increases and heat exchange efficiency deteriorates
Solution Approach 1:
The fan is designed with rotatable function, allowing it to switch between different orientations (refrigeration mode and heating mode). This dynamic adjustment enables the system to optimize airflow paths based on operational mode, reducing the negative impact of the water-receiving disk on heat exchange efficiency while maintaining effective water drainage functionality.
2Ease of operation
If the fan and heat exchanger arrangement is adjusted to achieve top air discharge and bottom air supply mode, then comfortability is improved, but device complexity increases
Solution Approach 1:
The air conditioner system is designed to perform multiple functions using the same core components. The fan and heat exchanger arrangement supports both refrigeration mode (top discharge, bottom supply) and heating mode operations, allowing the system to provide both cooling and heating comfortability without requiring separate dedicated components for each function, thereby avoiding excessive device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances airflow stability and heat exchange efficiency by reducing airflow obstruction, optimizing air volume and noise levels, and enabling efficient switching between refrigeration and heating modes.
Implementation Method 1
a fan, rotatably arranged in the shell... the orientation of an air-absorbing opening of the fan inclines upwards relative to a horizontal direction
Implementation Method 2
the ducted type air conditioner further includes a heat exchanger; the heat exchanger is arranged in the shell
Implementation Method 3
the water-receiving disk is located below the heat exchanger... to receive the condensed water generated on the heat exchange
