Pump Facility Power Input Adjustment for MRI Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump facilities in cooling systems for magnetic resonance facilities operate at full load, leading to excessive energy consumption and high operating costs, as they assume maximum cooling output requirements at all times, including during periods of lower demand.
Innovation Solution
The method involves adjusting the operating parameters of the pump facility, such as flow rate and power input, based on control information related to the examination object and the current operation of the magnetic resonance facility, to minimize energy consumption while ensuring adequate cooling output, by operating the pump facility with a predetermined minimal power input that matches the specific cooling requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump facility is operated at full load to ensure maximum cooling output, then the cooling reliability is improved, but the energy consumption increases excessively
Solution Approach 1:
The pump facility operates dynamically by adjusting its power input based on real-time cooling requirements. The control system monitors the operational state of the magnetic resonance facility and modulates the pump's power input accordingly, allowing it to transition between full load and reduced load operations, thereby resolving the contradiction between maintaining cooling reliability and reducing energy consumption
Solution Approach 2:
The patent changes the operating parameters of the pump facility by adjusting the power input level based on cooling demand. By varying the power input parameter from maximum to reduced levels according to the operational state of the magnetic resonance facility, the system achieves both reliable cooling when needed and energy efficiency when demand is lower
2Use of energy by moving object
If the pump facility power input is reduced at specific times, then the energy consumption decreases, but the cooling output becomes insufficient for maximum cooling requirements
Solution Approach 1:
The control system implements feedback by continuously monitoring the operational state of the magnetic resonance facility and adjusting the pump facility power input accordingly. When the magnetic resonance facility operates in modes requiring maximum cooling, the pump receives full power; when cooling demands are lower, the pump power is reduced, thus achieving energy efficiency without compromising cooling output when needed
Solution Approach 2:
The system dynamically adjusts the pump facility power input based on real-time cooling requirements. By making the power input variable rather than fixed, the system ensures that cooling output matches the actual demand, preventing both energy waste and insufficient cooling capacity
