SATUAN OPERASI PENGOLAHAN PANGAN

a       Refrigerating effect

= 385 kJ/kg – 255 kJ/kg

= 130 kJ/kg

b.      Refrigerating capacity

= Refrigerating effect*mass flow

= 130 kJ/kg*0.9 kg/s

= 117 kJ/s

c.       Compressor capacity

= 0.9 kg/s*0.130 m3/kg

= 0.117 m3/s

d.      Coefficient of Permanent = 385-255/425-385

= 0.75

= 75 %
