Technical Overview

A chiller removes heat from water or a suitable process fluid in its evaporator. Refrigerant is compressed, rejects heat in the condenser and returns through an expansion device to the evaporator. The water circuit and refrigeration circuit are separate.

Capacity and flow calculation

Refrigeration Cycle and Water Circuit

The evaporator absorbs heat from the liquid, the compressor raises refrigerant vapour pressure, the condenser rejects heat, and the expansion device lowers pressure. The process-liquid circuit is separate from the refrigeration circuit.

Technical assessment

The circulation pump carries cooled liquid to the user. Evaluate heat load, flow and temperature difference together; liquid temperature alone does not establish the load or electrical consumption.

Information needed for selection

Provide the application, operating hours, cooling load, entering and leaving liquid temperatures, fluid type and concentration, flow, site location and environmental conditions. A nominal capacity alone does not replace a detailed equipment selection.

Frequently asked question

Does this guide replace a product performance sheet?

No. It explains selection inputs and technical limits. Confirm the final model, capacity and options through a manufacturer selection at the actual operating conditions.
