Kitchen air conditioning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen air-conditioning systems lack efficient air supplementation to the range hood, leading to negative pressure and reduced energy efficiency, as they do not effectively combine air supplementation with heat exchange, and their designs are aesthetically unpleasing and inconvenient.
Innovation Solution
A kitchen air-conditioning system that integrates an air-conditioning assembly with a range hood assembly, using a four-way valve and secondary refrigerant pipes to connect heat exchangers, allowing fresh air to be supplemented and cooled before entering the kitchen and range hood, with a purifier and water management system to enhance energy efficiency.
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 achieved, 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 structure that provides both cooling and cooking functions without requiring separate installations
2Temperature
If a window unit is used, then cooling function is achieved, but a large square hole must be formed on the wall which destroys decoration
Solution Approach 1:
The integrated design eliminates the need for separate wall openings by combining the air-conditioning and range hood functions in one unit that can be installed as a single opening, preserving wall decoration
Solution Approach 2:
The device performs multiple functions (cooling and cooking) in one unit, making the single wall opening serve dual purposes and reducing the need for separate openings
3Temperature
If portable air conditioner is used, then cooling function is achieved, but manual connection to heat dissipation hose is inconvenient
Solution Approach 1:
The integrated unit combines air-conditioning and range hood functions, eliminating the need for separate hose connections and manual installations associated with portable air conditioners
4Quantity of substance
If kitchen window is opened for air supplementation, then air supplementation is achieved, but supplemented air may interfere with burning flame
Solution Approach 1:
The air-conditioning assembly acts as an intermediary device that supplements air through its own air intake and distribution system, using the refrigerating medium and heat exchanger to control air flow and temperature without directly exposing the flame to uncontrolled air streams
5Temperature
If existing kitchen air-conditioning system is used, then cooling function is achieved, but energy efficiency is reduced due to inability to combine air supplementation with heat exchange
Solution Approach 1:
The patent merges the air supplementation function with the heat exchange function by routing air through the refrigerating medium pipes and heat exchanger components, allowing the same system to both cool the kitchen and provide fresh air
Solution Approach 2:
The air-conditioning assembly performs multiple functions simultaneously: cooling the kitchen, supplementing air to the range hood, and heat exchange, thereby improving overall energy efficiency by eliminating the need for separate systems
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 system improves energy efficiency by reducing the intake-air temperature of the heat exchanger and providing effective air supplementation, enhancing the cooling effect while maintaining a compact and aesthetically pleasing design.

AI summary
A kitchen air-conditioning system comprises a air-conditioning assembly and a range hood assembly; the air-conditioning assembly comprising a compressor, a first heat exchanger and a second heat exchanger which are connected with each other through a plurality of refrigerating medium pipes; and the air-conditioning assembly has a fresh air inlet and a fresh air outlet, the fresh air coming from the fresh air inlet is divided into two paths; the fresh air entering the first heat exchanger flows into the kitchen through the fresh air outlet, and the fresh air entering the air intake area cools the third heat exchanger in the range hood assembly and is then exhausted to the outside through the range hood, which is helpful to reduce the intake-air temperature of the second heat exchanger, thereby improving the energy efficiency of the air conditioner.
