Duty

Comfort HVAC is typically LWT 6–7 °C at ΔT 5–6 K. Process duties vary — enter the loop your process needs. If you only have a heat load to remove, use load mode; if you're matching an existing loop, use flow mode.

Fluid & site

Glycol properties (cp, density, freeze point) are typical published values interpolated by concentration — the duty and flow correct automatically. Freeze rule of thumb: freeze point at least 5 K below the leaving water temperature.

Duty summary

Duty from Q = ṁ·cp·ΔT with fluid properties at the nominated glycol concentration. Chiller capacity varies with ambient and LWT — take this duty to the manufacturer's selection data or software for the actual machine. The printed duty spec contains everything a supplier needs to quote.
