1000 KG Capacity Air Cooled Water Chiller for Industrial Cooling Efficiency

Product Overview

Chiller

In cleanroom engineering projects, a chiller refers to an industrial refrigeration system based on vapor compression or absorption refrigeration cycles. Its core function is to cool a secondary refrigerant (typically chilled water) to a temperature range required by processes (commonly 7–12℃), and then deliver the cooled medium to HVAC terminal equipment and high-heat-generating process devices in the cleanroom through a closed pipeline system. As a critical supporting device, it provides a stable cold source for constant temperature and humidity control of the clean environment and heat dissipation of precision equipment, ensuring the cleanroom complies with standards such as ISO 14644 and GMP, and maintaining the stability of production and laboratory processes.

Features at a Glance

• Precise Regulation of Cleanroom Temperature and Humidity:Deliver chilled water at a constant temperature to the cleanroom HVAC system (e.g., constant temperature and humidity units, dry cooling coils) to precisely control indoor temperature (usually with an accuracy of ±0.5–2℃) and humidity (accuracy of ±2–5% RH). It prevents temperature and humidity fluctuations from damaging the clean environment, meeting the stringent environmental requirements of ISO Class 5–8 cleanrooms and standards such as GMP.
• Targeted Cooling for Process Equipment:Provide an independent process cooling loop for high-heat-generating process equipment in cleanrooms (e.g., semiconductor lithography machines, biopharmaceutical fermentation tanks, precision testing instruments). It timely removes heat generated during equipment operation, avoiding accuracy degradation, product yield reduction or experimental data deviation caused by equipment overheating.
• Ensuring Stability of Cleanroom Pressure Differential:Cooperate with the HVAC system to maintain a reasonable pressure differential gradient between the cleanroom and adjacent areas (e.g., a positive pressure of 5–20 Pa in the clean area relative to the non-clean area), preventing unpurified external air from infiltrating. Stable refrigeration output avoids pressure differential imbalance caused by system load fluctuations, ensuring that cleanliness is not compromised.
• System Energy Consumption Optimization and Energy-saving Operation:Support energy-saving modes such as variable frequency regulation and partial load operation. It dynamically adjusts cooling capacity output according to the real-time heat load of the cleanroom (e.g., changes in heat generation from personnel, equipment and fresh air) to reduce the overall energy consumption of the HVAC system. Some high-end models can be linked with waste heat recovery systems to further improve energy utilization efficiency.
• Dual Protection for Processes and Environment:Equipped with protection functions such as high-low temperature alarm, flow monitoring and fault shutdown. It issues timely warnings or shuts down when chilled water temperature or flow is abnormal, avoiding process interruption (e.g., a sharp drop in chip production yield) or cleanroom environment out of control caused by refrigeration failure. Meanwhile, the closed-loop design prevents chilled water contamination, ensuring hygiene and safety in industries such as and food.

Technical Specifications

Main Specification for Chiller

Cleanrooms typically require multiple, independent water systems with precise temperature control.

Note:A single chiller may serve one loop,or dual-temperature chillers may supply both chilled and reheat water simultaneously.

HVAC System Integration

The chiller can be integrated together with:

• Air Handling Units (AHU)
• Fan Filter Units (FFU)
• Ducting Systems
• Air Distribution Networks
• Building Management Systems (BMS)
• Temperature and Humidity Control Systems

This integration helps deliver a stable environmental control system for cleanroom facilities.
