It is proposed to build refrigeration plant for a cold storage to be maintained at -3°C. The ambient temperature is 27°C. If 5×10 6 kJ/h of energy is to be continuously removed from the cold storage, the minimum power required to run the refrigerator will be 14.3Kw 75.3 kW 154.3 kW 245.3 kW

Question

Susmita · Answer

I hope you know the relation (Q 1 /T 1 )=(Q 2 /T 2 ) where Q 1 =heat rejected in hot reservoir=5×10 6 kJ T 1 =temperature of hot reservoir=(27+273)K=300K Q 2 =heat absorbed from cold reservoir T 2 =temperature of cold reservoir=(-3+273)=300K Ussing the relation and putting the values Q 2 =5.55×10 6 kJ Work input=Q 1 -Q 2 =0.55 ×10 6 kJ Power=0.55kJ/h=(0.55×10 6 )/(60×60) kJ/s=154.3kJ/s=154.3 kW
