Ceiling mounted evaporator blower
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling-mounted air conditioning units are difficult to install and service due to their width exceeding the distance between ceiling joists, requiring significant retrofitting or removal of existing joists, and are costly and time-consuming.
Innovation Solution
A ceiling-mounted evaporator blower system with a chassis designed to fit between joists, featuring a pivotable mounting flange and diffuser assembly that allows toolless installation and maintenance, along with a diffuser assembly that inhibits condensation formation in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional ceiling mounted air conditioning units are installed, then cooling function is provided, but the unit width exceeds the distance between ceiling joists requiring significant retrofitting
Solution Approach 1:
The mounting flange is made pivotable relative to the chassis, allowing the unit to be installed in a compact configuration that fits between existing joists, then pivoted into its operational position. This dynamic mounting mechanism resolves the contradiction by enabling installation in spaces smaller than the unit's operational width would suggest.
2Length of moving object
If conventional ceiling mounted air conditioning units are installed, then cooling function is provided, but installation requires removal or relocation of existing ceiling joists
Solution Approach 1:
The pivotable mounting flange allows the unit to be installed in a compact configuration that accommodates existing joist spacing without requiring their removal or relocation, thereby maintaining structural integrity while enabling installation.
3Ease of operation
If conventional ceiling mounted air conditioning units are installed, then cooling function is provided, but servicing requires significant downtime and specialized tools in tight space
Solution Approach 1:
The pivotable mounting flange allows the chassis to be swung down from its installed position between the joists to an accessible service position, enabling technicians to service the unit without specialized tools and with minimal downtime, resolving the contradiction between ease of operation and time loss.
4Productivity
If the chassis is positioned above the ceiling between joists, then proper air flow pathway is established, but installation and maintenance become difficult in tight space
Solution Approach 1:
The pivotable mounting flange enables the chassis to be positioned above the ceiling between joists for optimal air flow, while also allowing it to be pivoted down to an accessible position for installation and maintenance, thus resolving the contradiction between productivity and ease of operation.
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
Facilitates easy installation and maintenance without disrupting existing joists, reduces installation costs, and prevents condensation in confined environments like wine cabinets.
Implementation Method 1
an evaporator positioned in the chassis and structured to cool air flowing through the chassis
Implementation Method 2
a fan assembly positioned in the air flow pathway

AI summary
An air cooling system includes a chassis dimensioned to fit between a pair of joists, an evaporator positioned in the chassis and configured to cool air flowing through the chassis, and a diffuser assembly. The diffuser assembly includes one or more positioning guides that toollessly couple the diffuser assembly to the chassis. The diffuser assembly is structured to enable passage of the cool air from the chassis though the diffuser assembly and to a diffuser outlet, and to inhibit formation of condensation caused by the cool air exiting the outlet.
