- Recommended system
- Air-cooled compact chiller (scroll compressor)
- Water/glycol flow (ΔT 5 K)
- 4.3 m³/h
- Water regime (supply/return): 15 / 20 °C · Recommended main pipe size: DN32 · Minimum buffer tank: 198 L
The calculation follows an ASHRAE-style item-by-item method and is for preliminary assessment. Final selection requires process data, a site survey and an engineering calculation.
1 kW = 3,412 BTU/h
The base coefficient used when converting between capacity units.
1 TR = 3.517 kW
Ton of Refrigeration is a unit commonly used in chiller selection.
ΔT 5 K flow rate
Water flow is calculated as Q / (1.163 × ΔT); the hydronic line is sized accordingly.
