System and method for controlling a medium parameter of the medium on the secondary side of a heat exchanger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat exchanger control systems require extensive cabling, leading to increased error susceptibility and costs due to the centralization of control units, which complicates the regulation of media parameters like temperature and humidity in secondary-side mediums.
Innovation Solution
Integrating the control unit directly into the actuator of the primary circuit, such as a pump or valve, allowing for local regulation of media parameters without external signal transmission, reducing cabling needs and improving signal transmission behavior.

Engineering Contradiction Analysis
1Ease of manufacture
If the control unit is arranged centrally in a switch cabinet, then the hydraulic and electrical parts are separated, but the cabling effort increases and error susceptibility rises
Solution Approach 1:
The control unit is segmented from the central switch cabinet and relocated to the actuator housing. This segmentation allows the electrical control components to be physically separated from the hydraulic components while maintaining functional integration, thereby reducing cabling requirements and error susceptibility.
Solution Approach 2:
The actuator housing serves as an intermediary structure that integrates both hydraulic and electrical components. By placing the control unit within the actuator housing, the patent creates a local control station that eliminates the need for extensive cabling between the switch cabinet and actuators.
2Ease of manufacture
If the control unit is arranged centrally, then system components are separated, but cabling costs and complexity increase
Solution Approach 1:
The control unit is merged with the actuator housing, creating an integrated control assembly. This merging eliminates the need for separate cabling connections between the central switch cabinet and individual actuators, thereby reducing cabling complexity while maintaining component functionality.
3Ease of manufacture
If control is centralized, then hydraulic and electrical parts are separated, but signal transmission distance increases
Solution Approach 1:
The control function is localized to each actuator by placing the control unit within the actuator housing. This localization ensures that signal transmission occurs over minimal distances between sensors, control units, and actuators, thereby maintaining high signal transmission quality and reducing information loss.
