Industrial Cooling Calculators

Browser-side tools for heat load, cooling duty, tower water, COP, effectiveness, thermal resistance and availability.

Estimate sensible heat moved by a liquid from flow, density, heat capacity and temperature change.

Estimate heat transfer from water flow and temperature difference using simplified assumptions.

Estimate makeup from user-entered evaporation, blowdown and drift.

Calculate simple concentration ratio from makeup and blowdown assumptions.

Calculate coefficient of performance from cooling output and electric input.

Calculate electricity use per unit of delivered cooling.

Compare actual heat transfer with user-entered maximum possible heat transfer.

Estimate one-dimensional conduction resistance for a simple layer.

Illustrate idealized affinity-law changes in flow and power from a speed ratio.

Calculate simple time availability from scheduled time and downtime.
