Radiator Upstream Fitting for True Partial-Load Serial Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to effectively convert standard radiators into radiators with a partial load effect, as they lack the necessary connections to achieve a real serial flow of the heating medium, leading to inefficient heating distribution and potential connection errors.
Innovation Solution
A ballast set comprising a lower connection block with separate fluid connections, a valve, a riser pipe, and an upper connection element, featuring screw-in nipples with molded seals to ensure the heating medium flows exclusively into or out of specific heating plates, allowing for conversion of standard radiators into radiators with a partial load effect, suitable for both one-pipe and two-pipe systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard radiators are converted using existing connection sets, then installation is simplified, but real serial flow cannot be achieved leading to ineffective partial load operation
Solution Approach 1:
The connection set is divided into separate functional components: an upper connection element with a first screw-in nipple for flow connection to the front heating plate, and a lower connection block with a second screw-in nipple for return connection to the rear heating plate. This segmentation enables proper serial flow configuration while maintaining ease of installation.
Solution Approach 2:
Screw-in nipples with molded seals act as intermediary elements that force the heating medium to flow in one direction through the T-piece connections. These intermediaries ensure unidirectional flow from the front heating plate through the riser pipe to the rear heating plate, achieving real serial flow while simplifying the conversion process.
2Temperature
If heating medium flows through multiple heating plates simultaneously, then heat distribution is achieved, but front panel temperature remains too low for effective radiation
Solution Approach 1:
The conventional parallel flow arrangement is inverted to a serial flow arrangement where the heating medium flows through the front heating plate first, then through the rear heating plate. This inversion ensures that the front heating plate receives the hottest heating medium first, maximizing its temperature and radiation efficiency before the medium cools in the rear plate.
Solution Approach 2:
The connection set utilizes hydraulic principles with screw-in nipples and molded seals to control and direct the flow of heating medium through the radiators. The sealed connections ensure proper pressure differential maintenance, forcing the heating medium through the front plate first and then to the rear plate, achieving optimal temperature distribution.
3Adaptability or versatility
If connection elements allow flexible flow paths, then installation adaptability is improved, but connection errors occur that impair partial load function
Solution Approach 1:
The upper connection element and lower connection block are designed with asymmetric features - the upper element has a first screw-in nipple configured for flow connection to the front heating plate, while the lower element has a second screw-in nipple for return connection to the rear heating plate. This asymmetry ensures correct installation orientation and prevents connection errors that would impair partial load function.
Solution Approach 2:
The molded seals integrated into the screw-in nipples provide self-aligning and self-sealing functionality during installation. The seals automatically engage with the T-piece connections, ensuring proper flow direction control without requiring additional sealing components or complex alignment procedures, thus preventing connection errors.

Function Achieved in This Case
Enables efficient conversion of standard radiators into radiators with a partial load effect, ensuring effective heating distribution and preventing connection errors, thereby enhancing heating performance with minimal effort on construction sites.
Implementation Method 1
the warm heating medium flowing into the front heating plate via the valve set has a lower density than that already in the heating plate located cooled heating medium and by gravity according to the principle of the communicating tube, the temperature level of the rear heating plate will adjust to the temperature level of the front heating plate

AI summary
The connector system for part load operation of radiators comprises a riser pipe (13) which feeds water exclusively to the front heating panel (2a) of the radiator and a drain (11a) which removes it exclusively from the rear panel (2b).
