Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an integrated structure mobile air conditioner is used, then it is movable and easy to install, but it produces high noise levels
Solution Approach 1:
The air conditioner system is divided into two separate units: a primary machine containing the noisy compressor and a secondary machine containing the evaporator and fan. This segmentation allows the noise-generating components to be isolated from the user environment while maintaining mobility through detachable connections between the two units.
2Object-affected harmful factors
If energy storage technology is adopted in mobile air conditioner, then noise is reduced during refrigeration, but working time is limited due to energy storage constraints
Solution Approach 1:
A heat storage medium serves as an intermediary between the primary machine and secondary machine, enabling thermal energy transfer without direct mechanical connection. This allows the system to operate in noise-reduced mode while the heat storage medium provides extended working capability by storing thermal energy for later use.
3Duration of action of moving object
If energy storage buffer box is provided for evaporator, then energy storage capability is enhanced, but system complexity increases
Solution Approach 1:
The heat storage medium pool is merged with the evaporator chamber, eliminating the need for a separate energy storage buffer box. The evaporator is directly immersed in the heat storage medium, combining the heat storage function with the heat exchange function in a single integrated structure, thereby enhancing energy storage capability without significantly increasing system complexity.

AI summary
A buffered balanced type mobile primary-secondary air conditioner system wherein three working media are used in primary-secondary air conditioner system. The first working medium is a compressor refrigeration working medium, the second working medium is an energy storage and heat transfer working medium shared by the primary machine and the secondary machine, and the third working medium is a secondary machine energy storage and heat transfer working medium. This scheme establishes a buffer balance zone between the primary machine and the secondary machine to store the second working medium.
