Solution Overview
Problem
Existing air conditioners have poor energy storage efficiency and struggle to meet diverse user requirements due to their limited operation modes and energy storage methods.
Innovation Solution
The air conditioner employs a first medium circulating system with serially connected heat exchanging units and throttling units, allowing for simultaneous room cooling and energy storage, using a second heat exchanging unit to efficiently store energy with a lower evaporation temperature, and includes control methods for various operation modes to enhance user flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the air conditioner operates in energy storage mode only, then the energy storage apparatus can store energy, but the use continuity is poor and different user requirements cannot be met
Solution Approach 1:
The air conditioner is designed to perform multiple functions through a single integrated system. The first medium circulating system can simultaneously execute room cooling and energy storage operations, or switch between different operation modes (energy storage mode, weak cooling mode, strong cooling mode) to meet diverse user requirements while maintaining high energy storage efficiency
2Adaptability or versatility
If the air conditioner cools the room first using the energy storage material, then stores energy, but this sequential approach reduces use continuity
Solution Approach 1:
The system enables continuous useful action by allowing simultaneous operation of room cooling and energy storage processes. The first medium circulating system can continuously cool the room through the first heat exchanging unit while continuously storing energy through the second heat exchanging unit, eliminating idle time and ensuring uninterrupted service
3Productivity
If a single heat exchanging unit is used, then the structure is simple, but the cooling efficiency and energy storage efficiency cannot be optimized simultaneously
Solution Approach 1:
The heat exchanging function is segmented into multiple independent units with specialized roles. The first heat exchanging unit is dedicated to room cooling, while the second heat exchanging unit is dedicated to energy storage. This segmentation allows each unit to be optimized for its specific function, improving overall cooling efficiency and energy storage efficiency without requiring an overly complex integrated structure
