During winter time a heat pump is operating on a heating mode to maintain a living room at 23oC during which the outside temperature is -5oC. The system is using R134a as a working fluid. The refrigerant leaves the condenser at 28oC and enters a compressor at -10oC. The refrigerant flow rate is 0.12kg/s. Assume an ideal VCC to evaluate the system and report the followings: a. Process diagram b. Heating capacity kJ/hr c. Coefficient of performance of the system...
