Question:-
In a vapour compressor refrigeration system, the compressor capacity is 2100 kj/minute and heat rejection factor is 1.2. What will, respectively be the heat rejected from the condenser and C. O0. P.?
Option (A)
5040 kJ/minute and 5
Option (B)
2520 kJ/minute and 5
Option(C)
2520 kJ/minute and 4
Option(D)
5040 kJ/minute and 4
Correct Option:
(B)
Question Solution:
In vapour compression refrigeration system, The heat is rejected in a condenser. The load on the condenser per unit of refrigeration capacity is known as heat rejection factor.
\ Heat rejected from condenser
= 1.2 x 2100 = 2520 KJ/min
and HRF = 1 + (1/COP)
Þ 1.2 = 1 + (1/COP)
\ COP = 5
