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:

Question
Transcribed Image Text: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 5ºC. 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 kJ/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?
