Portable AC Lift Mechanism for Duct-Aligned Exhaust Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable air conditioning units are inefficient due to pressure drops caused by hoses/pipes and noise from open condenser portions, with thermal bridges forming due to uninsulated components.
Innovation Solution
A portable air conditioning unit with a novel lifting mechanism that aligns intake and exhaust ports with an insulated duct at the windowsill, eliminating the need for hoses/pipes and incorporating a thermal shield to reduce noise and thermal bridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hoses/pipes are used to connect the air conditioning unit to the window panel, then the air conditioning unit can be installed, but pressure drop increases and efficiency decreases
Solution Approach 1:
The patent removes the hoses/pipes from the system entirely. Instead of using flexible hoses to connect the air conditioning unit to the window panel, the invention uses a rigid duct integrated into the window structure that directly receives air from the unit's ports, eliminating the intermediate connection elements that cause pressure drop and friction.
Solution Approach 2:
The duct is pre-installed in the window structure before the air conditioning unit is positioned. The duct includes pre-formed channels and openings that are ready to receive air directly from the unit's ports, eliminating the need for on-site hose connection and ensuring optimal alignment before operation begins.
2Temperature
If the condenser portion is open to the room, then heat dissipation is effective, but noise increases
Solution Approach 1:
The patent divides the housing into distinct segments: an open condenser portion for heat dissipation and a separate noise-shielding portion. The housing includes a front panel with a large opening for the condenser to be exposed to ambient air, while the rear portion contains noise-shielding material to attenuate sounds from the compressor and other noisy components.
Solution Approach 2:
Noise-shielding material is introduced as an intermediary element between the noisy internal components and the surrounding environment. This material absorbs and attenuates sound waves from the compressor and motor, reducing noise propagation while allowing the condenser to remain open for effective heat dissipation.
3Ease of manufacture
If hoses and window panel are not insulated, then installation is simple, but thermal bridges are created increasing heat or cold in the room
Solution Approach 1:
The duct is constructed as a composite structure with insulating material integrated into its walls. The duct includes an inner channel for air flow and outer walls filled with thermal insulation material, creating a composite structure that prevents thermal bridging while maintaining structural integrity and ease of installation.
Solution Approach 2:
The duct includes an insulating layer that acts as a thermal barrier between the air channel and the external environment. This insulating film or layer prevents heat transfer through the duct walls, eliminating thermal bridges without complicating the installation process.

AI summary
An AC unit with a lifting mechanism to lift or lower the AC unit relative to an insulated duct installed at a windowsill next to an insulated and relatively thick grill is disclosed. The AC unit includes multiple air conditioning components, a thermal shield integrated inside a housing, a skirt, and the lifting mechanism. A base portion of the housing is coupled to the top frame of the lifting mechanism. The lifting mechanism includes a pair of scissors pivoted to the bottom frame and the top frame. A telescopic skirt is arranged inside the bottom of the housing. The lifting mechanism ensures inlet and exhaust ports of the AC unit are aligned in a colinear fashion with respect to the duct so that the AC unit cools the condenser faster without wastage of effective air coming out of the air conditioning that would otherwise be used for cooling the room.
