Cooling Capacity calculation:
Total Cooling Capacity (TC) [KW] = Capacity in conditions table x F
T
Cooling Capacity in table [KW] Tubing Length Factor (F
T
) Corrected Capacity [KW]
11.5 0.85 TC = 11.5x0.85= 9.775
Cooling Pressure calculation:
Pressure [KPa(g)] = Nominal Pressure (at 7.5m) x F
T
Nominal Pressure [KPa(g)] Tubing Length Factor (F
T
) Corrected Pressure [KPa(g)]
Discharge 2500 0.99 Pd = 2500 x 0.99 = 2475
Suction 800 0.925 Ps = 800 x 0.925 = 740
