1.3.3 Reference Formula of Mould Controllers Model Selection
Heater Power (kW) = mould weight (kg) × mould specific heat (kcal/kg) × ℃
temperature difference between mould and environment () × safety coefficient ℃
/ heating duration / 860
Note: safety coefficient can select a value from 1.3 to 1.5.
Flow Rate (L/min) = heater power (kw) × 860 / [heating medium specific
(kcal/kg) × heating medium density (kg/L)×in/outlet temperature difference ℃
()× time (60)]℃
Note: Water specific heat =1kcal/kg℃
Heating medium oil specific heat =0.49kcal/kg℃
Water density =1kg/L
Heating medium oil density =0.842kg/L
