if similar system : a b c d
![During a fall season a heat pump is operating on a heating mode to maintain a
large convention hall at 24 C during which the outside temperature is 5°C. The
system is using R134a as a working fluid. The refrigerant leaves the condenser at
30°C and enters a compressor at -5°C. The refrigerant flow rate is 0.3 kg/s.
Assume an ideal VCC to evaluate the system and report the followings:
a. Draw the system
b. Draw process flow diagram for the cycle
c. Draw detail Ts diagram for this cycle
d. Heating capacity k]/hr
e. What is the COP of the system? Is actual COP is higher or lower? Explain.
f. What is the power required kW and hp?
g. What is maximum COP?
If similar system is used to maintain a large freezer at -0°C with an outside
temperature at 25°C.
a. Draw the system
b. Draw process flow diagram for the cycle
c. Draw detail Ts diagram for this cycle
d. What is the cooling capacity BTU/hr and tons of refrigeration?
e. Find COP. Is actual COP is higher or lower? Explain.
