Multi-Storey Water Tower Control for Heat Pump Air Conditioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water towers for water source heat pump central air conditioners consume excessive energy and are not suitable for controlling air-conditioning systems in multi-storey buildings on a storey-by-storey basis, leading to waste due to constant operation regardless of occupancy levels.
Innovation Solution
A water tower design with multiple return and supply pipes, small water pumps, and water temperature induction controllers allows for intelligent control of air-conditioning systems storey-by-storey, reducing energy consumption by dividing the main control water pump into smaller units and optimizing water distribution based on energy needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a main control water pump is designed to supply water to the whole building, then the water supply capability is improved, but the energy consumption increases excessively
Solution Approach 1:
The patent divides the single main control water pump into multiple small water pumps distributed across different storeys. Each small water pump serves a specific storey or zone, replacing the centralized large pump system. This segmentation allows water to be pumped only to the required height and location, significantly reducing the energy consumption while maintaining adequate water supply capability for the entire building.
Solution Approach 2:
The patent implements local water pumping stations at different storeys, where each small water pump is tailored to the specific water demand and height requirements of its local area. This local quality approach ensures that water is supplied with appropriate pressure and flow rate for each specific zone, rather than using a uniform high-capacity pump for the entire building, thereby optimizing energy efficiency.
2Reliability
If the main control water pump operates continuously to ensure water supply, then the reliability of water supply is improved, but the energy waste increases when occupancy is low
Solution Approach 1:
The patent introduces dynamic control mechanisms where small water pumps are activated only when needed in specific storeys. The system uses water level sensors and occupancy detection to dynamically switch pumps on or off, rather than maintaining continuous operation. This dynamic approach ensures water supply reliability is maintained in occupied areas while eliminating energy waste in unoccupied areas.
Solution Approach 2:
The patent implements feedback control systems with water level sensors and automatic control switches in each storey. When the water level in a local tank drops below a threshold or when occupancy is detected, the corresponding small water pump is automatically activated. When water levels are sufficient or areas are unoccupied, pumps are automatically shut off. This feedback mechanism maintains supply reliability while preventing energy waste during idle periods.
