Abstract
Description
Technical Field
[0001] This invention relates to the field of chilled water system technology, specifically to an automatic detection device and system for chilled water regulation. Background Technology
[0002] Chilled water systems are widely used in building HVAC systems, industrial refrigeration units, and other fields. The stability and rational adjustment of their operating parameters directly affect cooling efficiency, energy consumption, and equipment lifespan, making them a key factor in ensuring the efficient and reliable operation of related systems. In practical applications, chilled water systems need to dynamically adjust flow parameters according to changes in terminal load to achieve supply-demand matching and energy efficiency optimization.
[0003] Existing chilled water system regulation and monitoring mostly rely on manual inspections combined with manual valve adjustments. While this approach can initially meet basic regulation needs, it has significant shortcomings: manual response lags behind parameter changes, and the adjustment accuracy depends on operator experience, easily leading to fluctuations in parameters such as chilled water flow and temperature, affecting system stability. Some systems attempt to use fixed-parameter automatic adjustment devices, but these devices cannot dynamically adjust strategies based on actual end-load demands, resulting in a disconnect between regulation and load, causing energy waste. Furthermore, existing systems generally lack robust redundancy protection and stable power supply mechanisms, employing a single power supply and lacking data backup. Power outages or core module failures can easily cause operational interruptions and data loss, increasing maintenance difficulty and costs. Moreover, monitoring status primarily relies on distributed instruments, making maintenance cumbersome and information acquisition unintuitive. Therefore, this paper proposes an automatic chilled water regulation and monitoring device and system. Summary of the Invention
