Integrated Split Air Conditioner With Fresh-Air Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners lack a fresh air system, leading to indoor air quality issues due to climate, dust, and pollution, making it necessary to close doors and windows, which results in poor indoor air quality and health-related problems.
Innovation Solution
An air conditioner design that integrates an indoor unit, an outdoor unit, and a rigid connecting part with a fresh air vent and movable vent cover, allowing for easy installation and maintenance, while providing the quiet operation and energy-saving benefits of split-type systems, and incorporating soundproofing and decoration features to reduce noise and enhance aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional window-type air conditioner is used, then it is easier to install and maintain, but it generates noise and blocks sunlight and window space
Solution Approach 1:
The air conditioner is divided into two separate units: an indoor unit and an outdoor unit. The indoor unit is installed within the room while the outdoor unit is placed outside, separated by a wall penetration. This segmentation allows the noisy outdoor unit to be isolated from the living space, reducing noise impact while maintaining installation simplicity.
Solution Approach 2:
A wall penetration structure serves as an intermediary element connecting the indoor and outdoor units. This mediator allows refrigerant pipes and electrical connections to pass through the wall while providing sound insulation and structural support, enabling the split-type configuration without complicating installation.
2Object-affected harmful factors
If a split-type air conditioner is used, then noise is reduced and energy efficiency is improved, but installation and maintenance become more difficult
Solution Approach 1:
The system is segmented into standardized indoor and outdoor units with pre-configured connection interfaces. This segmentation allows each unit to be independently manufactured and tested, then assembled on-site through simple connection procedures, reducing installation complexity while maintaining noise reduction benefits.
Solution Approach 2:
The indoor and outdoor units are designed with self-aligning connection features and pre-installed mounting brackets. These self-service design elements enable technicians to quickly connect the units without requiring complex alignment procedures or specialized tools, reducing installation difficulty while preserving the quiet operation of the split-type configuration.
3Power
If conventional air conditioners are used, then cooling and heating functions are provided, but fresh air system is lacking leading to poor indoor air quality
Solution Approach 1:
The air conditioner is designed with multi-functionality, combining the traditional cooling and heating functions with a fresh air intake system. The outdoor unit includes a fresh air vent that can draw in outside air, which is then filtered and introduced into the indoor environment, providing air quality improvement alongside temperature control.
Solution Approach 2:
A movable vent cover acts as an intermediary component in the fresh air system. This vent cover can be adjusted to control the opening size of the fresh air vent, allowing users to regulate the amount of fresh air intake while maintaining the sealed environment needed for efficient cooling and heating 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
The integrated air conditioner system offers improved indoor air quality by providing fresh air, reduced noise, and energy efficiency, with simplified installation and maintenance, addressing the limitations of both window-type and split-type air conditioners.
Implementation Method 1
the rigid connecting part comprises a fresh air vent for introducing fresh air
Implementation Method 2
a movable vent cover to control an opening size of the fresh air vent
Implementation Method 3
Cooling in conventional air conditioner is accomplished using the vapor-compression cycle, which uses a refrigerant's forced circulation between indoor and outdoor units of the air conditioner, as well as phase change between gas and liquid to transfer heat
Implementation Method 4
phase change between gas and liquid to transfer heat
Implementation Method 5
The vapor-compression cycle can occur within an evaporator coil in the indoor unit and a condenser coil in the outdoor unit
Implementation Method 6
the fan is slowed to reduce the evaporator temperature and condense more water
Implementation Method 7
the compressor runs

AI summary
An air conditioner includes: an indoor unit; an outdoor unit; and a rigid connecting part which integrating the indoor unit and the outdoor unit; wherein the rigid connecting part has an indoor portion and an outdoor portion; the indoor unit is placed and mounted on the indoor portion of the rigid connecting part; and the outdoor unit is mounted to the outdoor portion of the rigid connecting part. A method for installing the air conditioner includes steps of: 1) opening a slot on a wall; and 2) inserting and mounting the air conditioner into the slot. With the foregoing structure and installation method, the air conditioner has the advantages of conventional window-type air conditioners such as being simple to install, cost-saving, and easy to maintain, as well as has the advantages of conventional split-type air conditioners such as long service life, sleek-looking, and being quiet.
