The condenser rejects evaporator heat together with compressor energy input. Heat-rejection duty is different from cooling capacity and must include the compressor contribution.

Air side

Inspect coil cleanliness, fan operation and airflow recirculation. Tight installation, hot-air return and fouling can worsen condensing conditions. Cleaning methods must suit the fin and coating construction.

Water side

Condenser-water temperature, flow and quality matter. Design the tower, pump and water treatment together. Cooling-tower duty is not simply a copy of evaporator kW.

Performance monitoring

Record ambient or condenser-water temperature alongside pressure and electrical input. Check the manufacturer operating limits and keep pressure protection active.

Project inputs and calculation boundaries

For a quotation, specify approximate heat duty, fluid, inlet and outlet temperatures, flow, pressure loss and operating hours. Design ambient conditions, indoor or outdoor location and electrical infrastructure are also selection inputs. Flow and temperature readings must represent the same operating point. Do not transfer a catalogue capacity directly to different temperatures; confirm model performance at the required duty.

Commissioning and operating records

Check circuit cleanliness, filtration, air removal, proven flow and sensor readings. Record reference water temperatures and load conditions during commissioning. These values provide a baseline for maintenance and alarm investigations. Confirm pumps, tanks, connections and control options against the agreed quotation scope.

Frequently asked questions

Is the series capacity range sufficient for final selection?

No. Confirm the actual model at the required fluid temperature, ambient conditions, fluid properties and hydraulic duty.

Is cooling capacity the electrical consumption?

No. Cooling kW and electrical-input kW are different quantities. An energy assessment also needs actual load and operating hours.

What information is needed for a quotation?

Provide the industry or equipment, target temperature, approximate duty, flow, ambient conditions, operating hours and details of the existing system.

These explanations provide general engineering guidance. Examples are not field measurements or performance guarantees for a particular model.
