High-precision chilled water unit The core difference between it and ordinary chilled water units lies in temperature control accuracy, system stability, and applicable scenarios. Its technological complexity and design optimization are particularly significant under ultra-high precision requirements of ±0.002℃. In industrial and commercial refrigeration fields, such as laboratories, semiconductor chip manufacturing, electronic component production, precision manufacturing, biomedicine, aerospace, and data centers, water-cooled chilled water units are indispensable equipment. High-precision water-cooled chilled water units and ordinary water-cooled chilled water units have significant differences, bringing unprecedented refrigeration experiences to many high-end industries. Today, let's delve into the differences between the two and experience the unique charm of high-precision water-cooled chilled water units.

I. Temperature Control Accuracy: Ordinary Units Cannot Match

Ordinary water-cooled chilled water units typically only achieve a temperature control accuracy of ±0.1℃ or even higher. This accuracy may suffice in some conventional industrial scenarios, but it is far from enough in high-end manufacturing and scientific research testing fields that are extremely sensitive to temperature. High-precision water-cooled chilled water units use self-developed temperature control technology, and the outlet temperature of the chilled water can reach a maximum accuracy of ±0.002℃. Taking semiconductor manufacturing equipment as an example, the chip manufacturing process is extremely sensitive to temperature changes; even minor temperature fluctuations can affect chip performance and yield. For EUV lithography machines (extreme ultraviolet), the cooling water consumption per unit/single production line is approximately 500-1000 L/h (circulation cooling), and the temperature fluctuation needs to be ±0.001℃ (±1 mK). Some key modules (such as laser light sources and optical lens groups) even require ±0.0005℃. High-precision water-cooled chilled water units, with their ultra-high precision, can precisely control the temperature, providing a stable cooling environment for semiconductor manufacturing and greatly improving product quality and production efficiency. During the operation of laser devices and optical equipment, subtle temperature changes will also affect the stability of the optical path and imaging quality. This level of stability is often the core guarantee for high-end manufacturing (such as 5nm chip processes) or cutting-edge scientific research, while ordinary units focus more on balancing cost and basic functions. The temperature control accuracy of ±0.002℃ ensures the high-performance operation of these devices.

II. Data Monitoring and Storage: Significant Differences in Intelligence

Ordinary water-cooled chilled water units have relatively simple data monitoring and storage functions, possibly only basic temperature display, lacking effective recording and convenient export methods for historical data. High-precision water-cooled chilled water units are equipped with large-capacity historical data storage functions and are also equipped with USB and Ethernet interfaces for users to easily export historical data. It supports the MODBUS TCP/IP protocol and can detect data online in real-time, displaying real-time outlet temperature changes in the form of curves. Operators can clearly understand the equipment's operating status through this data, promptly discover potential problems and make adjustments, achieving intelligent management of the equipment. This is crucial for ensuring stable equipment operation and optimizing cooling effects. The shortcomings of ordinary units in this aspect are obvious.

III. Application Scenarios: Precisely Matching Different Needs

Ordinary water-cooled chilled water units are mainly used in HVAC, electroplating, metallurgy, plastics manufacturing, and chemical industries with relatively low temperature accuracy requirements. In these industries, the performance of ordinary units is sufficient to meet production needs, and the cost is relatively low. High-precision water-cooled chilled water units are designed for equipment with stringent temperature control accuracy requirements, such as semiconductor manufacturing equipment, laser devices, optical equipment, X-ray fluorescence spectrometers, X-ray diffraction, and other industrial and testing machines' heat-generating parts. During operation, these high-end devices have extremely high requirements for temperature stability. The ±0.002℃ temperature control accuracy of high-precision water-cooled chilled water units can provide precise cooling control to ensure the normal operation of the equipment. This is a high-end application area that ordinary water-cooled chilled water units cannot easily enter. High-precision water-cooled chilled water units, with their ultra-high temperature control accuracy of ±0.002℃, powerful data monitoring and storage functions, and suitability for high-end equipment, far surpass ordinary water-cooled chilled water units in many aspects. If your industry involves high-end manufacturing, scientific research testing, etc., and has strict requirements for temperature control accuracy, then high-precision water-cooled chilled water units are undoubtedly your choice.
