Multi-connection air conditioning system and method for calculating heat exchange amount thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-connection air conditioning systems cannot calculate the heat exchange amount of each indoor unit separately, especially in air-cooled systems, as existing methods are limited to water-cooled systems and do not account for air-cooled configurations.
Innovation Solution
A method to calculate the heat exchange amount of each indoor unit in a multi-connection air conditioning system by obtaining the total heat exchange amount, inlet air temperature, two-phase saturation temperature, air supply volume, and heat exchange area, using a weight coefficient formula to determine the proportion of each unit's heat exchange capacity within the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing heat exchange amount calculation methods are used, then calculation can be achieved in water-cooled systems, but calculation cannot be performed in air-cooled multi-connection systems
Solution Approach 1:
The patent changes the fundamental calculation parameters from water flow-based measurements to air flow-based measurements. It introduces new parameters including air supply volume, inlet air temperature, two-phase saturation temperature, and heat exchange area to replace the traditional water-cooled measurement approach, enabling accurate heat exchange calculation in air-cooled systems
Solution Approach 2:
The patent creates a universal calculation method that can be applied to both water-cooled and air-cooled multi-connection air conditioning systems. By formulating a weight coefficient calculation that incorporates air-specific parameters, the method achieves multi-functionality across different system types while maintaining separate calculation capabilities for each indoor unit
2Ease of operation
If separate heat exchange amount monitoring for each indoor unit is implemented, then user management capability is improved, but calculation complexity increases
Solution Approach 1:
The patent segments the total heat exchange amount calculation into individual contributions from each indoor unit. It calculates a weight coefficient for each indoor unit based on its specific parameters (air supply volume, temperatures, heat exchange area), then distributes the total heat exchange amount proportionally to each unit, enabling separate monitoring without overwhelming complexity
Solution Approach 2:
The patent introduces a weight coefficient as an intermediary parameter to simplify the distribution of total heat exchange amount to individual indoor units. This intermediary factor, calculated from readily available basic parameters, acts as a mediator that translates system-level measurements into unit-level heat exchange amounts without requiring complex direct measurements for each unit
