The Development of Cooling Technology

Stored natural ice and evaporative methods preceded mechanical refrigeration. Mechanical systems expanded the ability to control heat transfer and operate at different temperature levels.

Technical assessment

Modern chillers are assessed through their heat exchangers, compressor, condenser, expansion device and controls. Historical progress does not establish the efficiency or environmental advantage of a particular modern unit.

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.
