Chiller Heat Load Calculator (ASHRAE-Aligned)
Use this calculator to estimate the heat load for chillers.
It applies the standard formula: Q (kW) = (Flow Rate in m³/s) × Density × Cp × ΔT (°C), as per ASHRAE SI standards.
Supports various flow units, includes optional ambient derating (0.9% per °C above 35°C), and safety factor. Results are given in kW and Tons (TR).
