A chiller is a machine that removes heat from a liquid (usually water or a water/glycol mix) and rejects that heat to the environment. The chilled liquid is circulated through equipment or air-handling units to provide cooling for processes or conditioned spaces.
Main uses
- HVAC: provides chilled water for air conditioning in commercial buildings, malls, hospitals.
- Industrial process cooling: cooling molds in injection molding, extrusion, metalworking (cooling cutting fluids, spindles), and plastic processing.
- Food & beverage: cooling products, tanks, fermentation control, cold storage.
- Pharmaceutical & chemical: temperature control for reactors, stability chambers, and cleanrooms.
- Data centers & telecom: removes server heat to protect equipment and maintain reliability.
- Medical & lab equipment: MRI, laser systems, analytical instruments that require stable cooling.
- Breweries & wineries: fermentation temperature control and wort cooling.
Types and technology (brief)
- Vapor-compression chillers: most common; use a compressor, condenser, expansion valve and evaporator. Variants: scroll, screw, reciprocating, centrifugal.
- Absorption chillers: use heat (steam, hot water, or gas) plus a refrigerant/absorbent pair (e.g., water/lithium bromide); used where waste heat or steam is available.
- Air-cooled vs water-cooled: air-cooled reject heat to ambient air (fan-cooled); water-cooled use a cooling tower and are more efficient in large installations.
- Low-temperature options: use brine or specialty refrigerants for temperatures below freezing.
Benefits
- Precise temperature control for processes and comfort.
- Improved product quality, higher yields and reduced downtime in manufacturing.
- Centralized cooling often more efficient and easier to maintain than many small units.
- Humidity control (when used with HVAC systems).
Key selection factors
- Cooling load (kW or tons of refrigeration).
- Required chilled-water temperature and flow rate.
- Duty cycle and redundancy needs.
- Site constraints (available water, space, ambient conditions).
- Efficiency (COP, EER), lifecycle cost and refrigerant choice.
- Maintenance capability and local regulations (refrigerant handling).
Typical performance notes
- 1 ton of refrigeration ≈ 3.517 kW.
- Chilled-water supply for comfort cooling commonly 5–7 °C; process needs vary widely.
- Typical COP (vapor-compression) often between 3 and 7 depending on size and conditions.
Basic maintenance items
- Keep condensers/air-coils clean, change filters.
- Monitor refrigerant charge, oil levels, belts, bearings.
- Treat water in water-cooled systems to prevent scaling and biological growth.
- Check controls, safety devices and piping insulation.
If you tell me the application you have in mind (building HVAC, plastics, data center, small lab, etc.), I can suggest the best chiller type, typical size range, or selection considerations.
