Industrial chillers

Applicable Standards

Industrial chillers adhere to global safety and performance regulations, including:

• ASHRAE 15 (Safety Standard for Refrigeration Systems)
• ISO 5149 (Refrigerating Systems and Heat Pumps)
• UL 1995 (Heating and Cooling Equipment)
• CE Marking (EU Safety, Health, and Environmental Requirements)
• GB/T 18430.1 (China’s National Standard for Vapor Compression Chillers)

These standards ensure energy efficiency, safety, and reliability across industries.

Working Principle

Chillers operate via a vapor-compression refrigeration cycle:

1. Evaporation: Low-pressure refrigerant absorbs heat from the coolant (e.g., water/glycol mix) in the evaporator.
2. Compression: A compressor increases refrigerant pressure and temperature.
3. Condensation: High-pressure gas releases heat to the environment via air-cooled fins or water-cooled towers.
4. Expansion: The refrigerant expands, lowering its temperature before re-entering the evaporator.

For air-cooled models, fans dissipate heat; water-cooled systems use external cooling towers.

Test Principle & Applications

Chillers are tested for:

• Temperature Stability: ±0.1°C control accuracy under load.
• Efficiency: Coefficient of Performance (COP) ratings ≥3.5 for energy savings.
• Pressure Resistance: Leak tests ensure system integrity.

Key applications include:

• Plastics Industry: Cooling molds to prevent defects.
• Medical Devices: Stabilizing MRI/CT scanner temperatures.
• Food & Beverage: Chilling process lines or fermentation tanks.
• Laser Systems: Preventing overheating in cutting/engraving machines.

Industrial chillers are indispensable for processes requiring precise thermal management, offering durability, energy efficiency, and compliance with stringent industry standards.
