Universal air handler unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile homes and small structures, the scarcity of indoor space poses challenges for air conditioning systems, particularly with the increasing size of high-efficiency outdoor condenser and compressor units, leading to the need for a solution that conserves interior space while accommodating larger outdoor units.
Innovation Solution
A universal air handler unit is designed with a compact, weather-resistant cabinet housing a blower and evaporator for outdoor installation, coupled with a stand-alone condenser/compressor unit, allowing for flexible placement and reduced footprint through stacking and modular duct connections, enabling efficient use of space and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If higher efficiency condenser and compressor units are used, then energy efficiency is improved, but the physical size of the outdoor unit increases
Solution Approach 1:
The system separates high-efficiency condensing components from the evaporator/blower unit, allowing the condenser/compressor unit to be optimized for energy efficiency with advanced components while maintaining a compact footprint. The evaporator unit handles air movement and cooling distribution, enabling each component to be sized appropriately for its function rather than requiring a large all-in-one package.
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 allows for the use of higher efficiency outdoor units within the limited space constraints of mobile home parks, providing flexible installation options and reducing the need for dedicated indoor space, while minimizing damage to ducts and enhancing maintenance accessibility.
Implementation Method 1
Return air drawn by the blower into the cabinet passes across the evaporator core
Implementation Method 2
Return air drawn by the blower into the cabinet passes across the evaporator core, then through the blower and back out

AI summary
A universal air handler unit includes a blower and evaporator juxtaposed one another within a compact, weather resistant cabinet adapted for outdoor installation. Ports for cool and return air ducts disposed on one side of the cabinet couple directly to the blower and evaporator respectively. Return air drawn by the blower into the cabinet passes across the evaporator core, then through the blower and back out through the adjacent cool air duct. Coolant lines couple to a stand-alone condenser/compressor unit. In a particular embodiment, an adapter enables stacking the condenser/compressor unit atop the cabinet to reduce the overall footprint of the combination. In another embodiment, a manifold adapted to couple to the cool and return air ducts may be installed in various locations, the air handler unit slideably coupling to the manifold during installation, and easily decoupling and reecoupling for transportation and maintenance.
