Regulation method for regulating an air conditioning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning systems struggle to individually regulate temperature in multiple zones with different requirements, as they rely on dividing a single airflow using bypasses, which can offset flows and prevent precise control over each zone.
Innovation Solution
A regulation method that includes a thermal cycle machine, a distributor with adjustable valves for each zone, and a central processing unit to manage fan speed and temperature set points, allowing for independent control of airflow to each zone based on measured and set-point temperatures, pressures, and thermal inertia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single airflow is divided into smaller flows using bypasses to conduits, then the airflow can be distributed to multiple zones, but individual regulation of each zone becomes impossible due to flow offset
Solution Approach 1:
The distributor is divided into multiple independent branches, each serving a specific zone. Each branch is equipped with its own adjustment mechanism (grating or valve), allowing independent control of airflow to each zone without affecting other zones. This segmentation resolves the flow offset problem by creating separate control pathways.
Solution Approach 2:
The system incorporates adjustable gratings at conduit outlets and adjustable valves within branches, enabling dynamic regulation of airflow. These adjustable elements allow each zone to independently control its airflow quantity and direction, transforming the static distributed system into a dynamically controllable one.
2Ease of operation
If adjustable outlets are used to regulate individual zones, then zone-specific temperature control is possible, but all other flows are offset
Solution Approach 1:
The distributor is segmented into independent branches with separate adjustment mechanisms. Each branch can regulate its airflow independently through adjustable valves or gratings, allowing zone-specific temperature control without disrupting the airflow distribution to other zones, thus maintaining overall system efficiency.
Solution Approach 2:
Each zone is equipped with its own local adjustment mechanism (grating or valve) that allows independent regulation of airflow characteristics. This local control capability enables precise temperature control in each zone without affecting the global airflow balance of the system.
3Ease of operation
If the thermal cycle machine operates at fixed conditions, then the system is simple to operate, but it cannot meet different temperature requirements of multiple zones
Solution Approach 1:
The thermal cycle machine is equipped with adjustable parameters including fan speed and refrigerant charge quantity. These dynamic adjustments allow the machine to adapt its operating conditions to meet the diverse temperature requirements of multiple zones while maintaining relatively simple operation through centralized control.
Solution Approach 2:
The system allows modification of key operating parameters of the thermal cycle machine, such as fan speed and refrigerant charge. By changing these parameters, the system can adapt to different thermal demands of multiple zones without requiring complex structural modifications, maintaining operational simplicity while enhancing versatility.
