The unit of chiller capacity is typically measured in tons of refrigeration (TR) or kilowatts (kW). These units represent the cooling power of the chiller, indicating how much heat the system can remove from the space or process in a given time.

1. Tons of Refrigeration (TR)

  • One of the most common units used to measure chiller capacity is the ton of refrigeration. One ton of refrigeration is defined as the amount of heat needed to melt one ton of ice over a 24-hour period.
  • 1 Ton of Refrigeration (TR) = 12,000 BTU/hr (British Thermal Units per hour).

Example:

A chiller with a capacity of 100 tons can remove 1,200,000 BTU/hr of heat. This measurement is widely used in commercial and industrial settings.

2. Kilowatts (kW)

  • In many regions, especially in Europe and other international markets, kilowatts (kW) is used as the unit of chiller capacity. Kilowatts measure the rate of energy transfer and are commonly used for HVAC and industrial cooling applications.
  • 1 kW = 3,412 BTU/hr, so a 100-ton chiller would be equivalent to about 351.7 kW.

Conversion Formula:

1 ton=3.517kW1 \text{ ton} = 3.517 kW

Example:

A chiller with a capacity of 100 tons is equivalent to approximately 351.7 kW of cooling power.

Why is Chiller Capacity Important?

Chiller capacity is essential to ensure the system can effectively meet the cooling demands of the application. Whether you are cooling a commercial space or an industrial process, selecting the right chiller size helps achieve energy efficiency and optimized performance.

For example, in commercial buildings, Air-Cooled Water Chillers in Ahmedabad might range from 50 to 500 tons to meet HVAC needs, while Water Cooled Screw Chillers in Ahmedabad in industrial settings can have capacities well beyond 500 tons.

Applications of Chillers by Capacity

  • Small Capacity Chillers: Typically range from 1 to 50 tons (3.5 kW to 175 kW). These are used in small commercial spaces, offices, and HVAC systems.
  • Medium Capacity Chillers: Range from 50 to 500 tons (175 kW to 1755 kW). Common in hospitals, large office complexes, and industrial cooling.
  • Large Capacity Chillers: Over 500 tons (1755 kW+). These are used in large industrial processes, data centers, and manufacturing plants.

Conclusion

The unit of chiller capacity is typically measured in tons of refrigeration (TR) or kilowatts (kW). Whether you’re dealing with Air-Cooled Screw Chillers in Ahmedabad or Water Cooled Water Chillers in Ahmedabad, understanding the capacity unit is crucial for selecting the right chiller for your application.
