In a heat pump operating according to the vapor compression refrigeration cycle, the refrigerant is R-134a. A water source of 11 °C is used to heat a house with a heating load of 17 kW. Refrigerant enters the compressor as saturated steam at 100 kPa pressure and rises at 1.6 MPa, 60 ° C. The temperature of the refrigerant at the outlet of the condenser is 30°C. a) The amount of heat at the beginning of the water, b) Compressor...

Problem #3 Refrigerant R-134a enters the condenser of a heat pump at 1000 kPa and 80°C at a rate of 0.025 kg/s and leaves at 1000 kPa as saturated liquid. If the compressor consumes 2 kW of power, determine: a) The COP of the heat pump (as heating device). b) The rate of heat absorption from the outside air. тан Condenser Throttling valve Compressor Evaporator To

In a vapor-compression refrigeration heat pump cycle with Refrigerant 134a as the working fluid provides heating at a rate of 15 kW to maintain a building at 20 °C year-round. During the heating mode in the winter, the outside temperature is 5 °C. It is also used for cooling in the summer when outside temperature is 34 °C. Saturated vapor at 2.4 bar leaves the evaporator and superheated vapor at 8 bar leaves the compressor. There is no significant heat...

Problem #2 (30 The steam cycle described in Problem #1 wasted a significant amount of exergy to the cooling water. A real cycle might cascade the energy down to a lower temperature cycle to utilise some of this exergy (regeneration). It might also use the heat to execute an industrial process (cogeneration). The cycle described below does both! inSeam generator Turbine 1.5 bar H20 cycle To industrial process H2OR-134a heat exchanger Turbine Refrigerant cycle R-134a cycle Pump Condenser Pump Return...

5. The refrigeration system shown below is another variation of the basic vapor compression refrigeration system which attempts to reduce the compression work. In this system, a heat exchanger is used to superheat the vapor entering the compressor while sub-cooling the liquid exiting from the condenser Consider a system of this type that uses refrigerant-134a as its refrigerant and operates the evaporator at -10°C, and the...

1. (20 points) Consider a cogeneration system operating at steady state. Superheated steam enters the first turbine stage at 6 MPa, 540 °C. Between the first and second stages, 45% of the steam is extracted at 500 kPa and diverted to a process heating load of 5 x 108 kl/h. Condensate exits the process heat exchanger at 450 kPa with specific enthalpy of 589.13 kl/kg and is mixed with liquid exiting the lower pressure pump at 450 kPa. The entire...
