Segmented Kitchen Cooling Arrangement for Aircraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling arrangements for aircraft kitchens require a large amount of installation space due to their fully integrated architecture, limiting flexibility and efficient use of space.
Innovation Solution
The cooling arrangement is divided into a separate condenser unit and evaporator unit, allowing each to occupy less space and be installed in different areas of the kitchen, with the evaporator positioned near devices to be cooled and the condenser in a separate location, optimizing space utilization and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all cooling components are integrated in a common housing, then mechanical interfaces are eliminated and reliability is improved, but installation space requirement increases
Solution Approach 1:
The cooling arrangement is segmented into separate functional units: a condenser unit with the condenser and a evaporator unit with the evaporator, allowing each unit to be installed in different locations within the kitchen, thereby reducing the concentrated installation space requirement while maintaining system reliability through modular design
2Device complexity
If the cooling arrangement is fully integrated, then device complexity is reduced, but installation space requirement increases
Solution Approach 1:
The cooling arrangement is divided into a condenser unit and a evaporator unit that can be installed separately in different locations, reducing the overall installation space footprint while maintaining relatively simple device complexity through standardized modular components
Solution Approach 2:
A control unit acts as an intermediary between the separate condenser and evaporator units, coordinating their operation to achieve the desired cooling effect while allowing physical separation of the main cooling components, thus reducing installation space requirements
3Productivity
If the evaporator is positioned near the device to be cooled, then cooling efficiency is improved, but installation space for the condenser becomes more constrained
Solution Approach 1:
The cooling arrangement is segmented into spatially separated condenser and evaporator units, allowing the evaporator to be positioned close to the device requiring cooling (improving cooling efficiency) while the condenser is installed in a different location with adequate space (maintaining installation feasibility)
Solution Approach 2:
The system transitions from a centralized three-dimensional arrangement to a distributed spatial configuration, utilizing different locations within the kitchen space to accommodate separate condenser and evaporator units, thereby optimizing both cooling efficiency and installation space utilization

Function Achieved in This Case
This configuration reduces the overall installation space required and allows for flexible placement of cooling components, enabling efficient cooling of various kitchen devices and compartments while minimizing the need for mechanical interfaces.
Implementation Method 1
As it flows through the evaporator, the cooling medium flowing through the cooling circuit absorbs heat from a fluid which is to be cooled
Implementation Method 2
the cooling medium is transferred in the process from the liquid into the gaseous state
Implementation Method 3
as it flows through the condenser, the cooling medium flowing through the cooling circuit is cooled by virtue of heat energy being dissipated to a heat-absorbing fluid
Implementation Method 4
the cooling medium is converted back again from the gaseous into the liquid state

AI summary
A cooling arrangement for a kitchen provided for installation in a means of transport comprises a cooling circuit which can have a cooling medium flowing through it and in which a condenser and an evaporator are arranged. The condenser is accommodated in a condenser housing and is arranged in a first installation space which is intended to form a first sub-region of the kitchen. The evaporator is accommodated in an evaporator housing formed separately from the condenser housing, and is arranged in a second installation space which is intended to form a second sub-region of the kitchen.
