Industrial Chilled Water Cooling Capacity (HVAC)
Calculate industrial chiller cooling duty (Tons of Refrigeration & kW) from chilled water flow rate and temperature difference (ΔT).
💡 Engineering Knowledge PrimerChilled water system capacity measures the rate of thermal energy extraction from process circuits or building HVAC. One Ton of Refrigeration (1 TR = 12,000 BTU/h = 3.517 kW) represents the heat required to melt one short ton of ice in 24 hours.
CALCULATION SCOPE — Deterministic calculation within the published assumptions. Independently verify all design decisions and project-specific code requirements.

Technical Methodology & Engineering Principles
GOVERNING EQUATION
Thermal Duty Q (kW) = Mass Flow (kg/s) × Cp (4.184 kJ/kg·K) × ΔT (°C)
Capacity (TR) = Q (kW) / 3.517 kW/TR
Assumptions & Scope
Clean process water specific heat capacity Cp = 4.184 kJ/kg·°C.
Operating Range & Boundary
Use finite, physically meaningful inputs within the stated operating assumptions.
