A vapor-compression refrigeration system has a refrigerating effect of 140 kJ/kg. What refrigerant mass flow rate is needed for a capacity of 10 tons of refrigeration? (1 TR = 3.517 kW)
- 0.0714 kg/s
- 3.9807 kg/s
- 0.2010 kg/s
- 0.2512 kg/s
Answer
D. 0.2512 kg/s
Solution
m = Q/RE = (10 × 3.517)/140 = 0.2512 kg/s.
