Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen air-conditioning systems are aesthetically unpleasing, inefficient in heat dissipation, and lack integration with range hoods, leading to reduced energy efficiency and the need for separate installations in each kitchen.
Innovation Solution
A central air-conditioning system with shared air-conditioning and range hood assemblies connected through a public flue and secondary refrigerant channels, allowing heat exchange and fume exhaust, featuring a compressor, heat exchangers, and a flue fan for efficient heat dissipation and fume management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a split kitchen air-conditioner is used with outdoor unit hung outdoors, then cooling function is provided, but the structure is not compact and aesthetically pleasing
Solution Approach 1:
The patent combines the air-conditioning unit and range hood into a single integrated device, merging two separate appliances into one compact unit that provides both cooling and fume extraction functions, eliminating the need for separate outdoor units and improving aesthetics
Solution Approach 2:
The integrated unit performs multiple functions including cooling, heating, and fume extraction through a single device, allowing the same appliance to serve multiple purposes in the kitchen environment
2Temperature
If a window unit is used with large square hole in wall, then cooling function is provided, but the decoration is destroyed and it is messy when not in use
Solution Approach 1:
The air-conditioning unit is integrated with the range hood into a single compact device that can be installed in a standard kitchen opening, eliminating the need for large square holes and maintaining wall decoration integrity
Solution Approach 2:
The air-conditioning components are nested within the range hood structure, with the evaporator and condenser units integrated into the existing range hood housing, creating a compact nested arrangement
3Reliability
If kitchen air-conditioner and range hood operate independently, then each device functions separately, but heat dissipation efficiency is reduced and energy efficiency is lowered
Solution Approach 1:
The air-conditioning system and range hood are merged into a single integrated unit where the range hood fan serves dual purposes: extracting cooking fumes and dissipating heat from the air-conditioning condenser, eliminating energy waste
Solution Approach 2:
The range hood fan automatically serves the dual function of fume extraction and heat dissipation without requiring separate systems, using its own operational capacity to benefit both cooking ventilation and air-conditioning cooling
4Temperature
If separate air-conditioning systems are installed in each kitchen, then each kitchen has independent cooling, but the structure is not compact and installation complexity increases
Solution Approach 1:
A single integrated unit provides both air-conditioning and fume extraction functions, reducing the number of separate devices needed and simplifying installation while maintaining effective cooling performance
Solution Approach 2:
Multiple functions are combined into one unit, reducing the overall system complexity and number of components that need to be installed and maintained across multiple kitchens

AI summary
A central air-conditioning system, comprises a plurality of air-conditioning assemblies (1) and a plurality of range hood assemblies (2); each air-conditioning assembly (1) comprises a compressor (11), a first heat exchanger (12) and a second heat exchanger (13) which are connected with each other through refrigerating medium pipes (14); all the range hood assemblies (2) are in communication with the public flue (6); a third heat exchanger (3) and the second heat exchanger (13) is connected through a secondary refrigerant channel (4); each end of each secondary refrigerant channel (4) respectively exchanges heat with the second heat exchanger (13) and the third heat exchanger (3). As all the range hood assemblies (2) are in communication with the public flue (6), the third heat exchanger (3) exchanges heat with the second heat exchangers (13) through the secondary refrigerant channel (4), when the system is operating, the heat energy generated by the air-conditioning assemblies (1) can be discharged through the public flue (6).
