Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for charging a coolant into a cooling system via a hose are inaccurate due to variations in hose length, internal diameter, supply pressure, and temperature differences, leading to inconsistencies in the amount of coolant delivered, especially when using gaseous coolants.
Innovation Solution
Implementing temperature and pressure sensors at both the inlet and outlet ends of the hose, connected to a computer with software that calculates and compensates for density changes to ensure precise charging through a flow valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If charging is performed via a hose with variable length and diameter, then the charging process can be performed, but measurement precision deteriorates due to density variations along the hose
Solution Approach 1:
The patent applies parameter changes by measuring temperature and pressure at both inlet and outlet of the hose to calculate density variations. The computer processes these parameter changes to compensate for density differences caused by pressure drop and temperature variations along the hose, thereby achieving accurate charging amount measurement despite the hose's variable characteristics
Solution Approach 2:
The patent implements feedback control by using sensors to continuously monitor temperature and pressure at both ends of the hose, feeding this data to a computer that calculates the actual charged amount. The system uses this feedback information to compensate for density variations and provide accurate charging measurements, resolving the contradiction between measurement precision and device complexity
2Quantity of substance
If hose length and internal diameter are increased, then charging capacity is improved, but measurement precision deteriorates due to greater density variations
Solution Approach 1:
The patent measures temperature and pressure parameters at both inlet and outlet of the hose to calculate density variations. By monitoring these parameter changes along the hose length, the system compensates for density differences that occur with longer hoses, maintaining measurement precision while allowing increased charging capacity
Solution Approach 2:
The patent replaces direct mechanical measurement of charged amount with a computational approach. Instead of relying on mechanical flow meters that are inaccurate over long hoses, the system uses temperature and pressure sensors combined with computer-based density calculations to determine the actual charged amount, enabling accurate measurement regardless of hose length
3Productivity
If pressure drop through the hose is reduced, then charging efficiency is improved, but measurement precision deteriorates due to smaller density differences being harder to detect
Solution Approach 1:
The patent uses continuous feedback from temperature and pressure sensors at both hose ends to detect even small density variations. The computer processes these feedback signals to calculate the actual charged amount, enabling precise measurement regardless of the magnitude of pressure drop, thus maintaining both charging efficiency and measurement precision

AI summary
To ensure precise charging of a coolant into a cooling system (6) via a hose (4), temperature sensors (Ts and Te) and pressure sensors (Ps and Pe) are mounted at the inlet side and/or outlet side of the hose (4). A signal may be applied from these sensors to a computer (11), which is capable of calculating the amount pumped through the hose (4) and thereby controlling it via a valve (5). It is ensured in this manner that the charged amount is determined on the basis of its density and not, as was previously the case, solely on the basis of a weight control.
