High-precision water-cooled chiller is a unit specifically designed for critical environments with extremely high requirements for temperature and humidity control precision and requiring continuous and stable cooling It is the core equipment of the air conditioning system for such environments. Its core function is to provide high-precision and high-stability chilled water as a refrigerant delivered to terminal air handling equipment (such as precision air conditioners, fan coil units, etc.), thereby achieving precise temperature and humidity control of the environment.

Its main functions and features are reflected in the following aspects:

Provides ultra-high precision temperature control:

Can control the outlet water temperature of the chilled water within an extremely narrow fluctuation range (e.g., ±0.05°C, ±0.005°C).

This is crucial for sensitive equipment and processes, as even minor temperature fluctuations can affect performance, accuracy, lifespan, or product quality.

Provides high stability and reliability:

Employs redundant design (such as dual compressors, dual water pumps, dual circuits, etc.) to ensure 7x24 uninterrupted operation.

Features powerful fault diagnosis and protection functions to prevent unexpected shutdowns.

High-quality components and strict manufacturing processes ensure long-term stable operation.

Meets the high cooling capacity requirements of critical environments:

Typically used in locations with extremely high heat density (such as data center server rooms, large communication equipment rooms, high-power laser equipment, large medical imaging equipment, etc.), and can provide large cooling capacity.

Water-cooled heat dissipation is more efficient than air cooling, especially suitable for large-scale, high-density heat dissipation scenarios.

Achieves high-efficiency operation:

The water-cooled condenser uses cooling tower water for heat dissipation, which is more efficient than the air-cooled condenser, especially at higher ambient temperatures.

Typically equipped with high-efficiency compressors (such as variable frequency scroll compressors, variable frequency centrifugal compressors), high-efficiency water pumps, and intelligent control systems, which can dynamically adjust the output according to the actual load, significantly reducing operating energy consumption (lower PUE value).

This is particularly important for large-scale facilities (such as data centers) that are sensitive to operating costs.

Supports precise humidity control (indirectly):

Although the unit itself mainly controls the water temperature, stable and precise chilled water temperature is the basic guarantee for terminal precision air conditioners to achieve precise humidity control (by adjusting the dehumidification amount of the cooler and the operation of the humidifier).

Reduces noise and vibration:

The main noise sources (compressor, cooling tower) are usually placed in areas away from the precision environment (such as the roof, equipment room).

The unit itself is designed with a focus on vibration reduction and noise reduction to minimize interference with sensitive equipment.

Typical application scenarios:

Data centers:   Provide a constant temperature and humidity environment for servers and network equipment, ensuring reliable operation of IT equipment and data security. This is currently the main application area.

Communication rooms:   Heat dissipation for key communication equipment such as switches and base station controllers.

Medical facilities:

Large medical imaging equipment rooms (MRI, CT, PET-CT, etc.).

Biological laboratories, sample banks (requiring precise temperature and humidity).

Clean operating rooms, aseptic pharmaceutical workshops (requiring a stable environment).

Industrial manufacturing:

Precision electronics manufacturing (semiconductor wafer fabs, chip testing, SMT workshops).

Precision optical instrument manufacturing and testing.

Laser processing equipment cooling.

Processing of special materials (materials sensitive to temperature).

Laboratories and research institutions:

Metrology and calibration laboratories.

High-performance computing centers.

Physics, chemistry, and biology laboratories with strict temperature and humidity requirements.

Museums, archives:   Protect valuable cultural relics, ancient books, and works of art from damage caused by temperature and humidity fluctuations.

In summary, the core function of a high-precision water-cooled chiller is:

To provide a continuous, stable, ultra-high precision, and energy-efficient chilled water source for key facilities or processes with high heat generation and extremely demanding temperature and humidity requirements, ensuring that internal sensitive equipment or processes can operate safely, reliably, and accurately.

It is an indispensable basic environmental protection equipment in modern data centers, high-end manufacturing, cutting-edge scientific research, and precision medical fields.
