Please help with HW 37
Qoutl condenser Condenser A standard 4-component vapor-compression cycle using R-134a is shown in the figure to the right. The cycle is used as a refrigeration cycle to cool a refrigerator at 5 °C with a cooling capacity of 200 W, with a heat transfer to a kitchen at 20 °C. Assume that the pressure drops in the evaporator and condenser are negligible, and that the compressor and expansion valve are adiabatic. Take the boundary temperature...

A heat pump using R134a refrigerant is used to hold a medium at 23c. In the evaporator part, geothermal water (cp = 4.18) with 0.0045 flow rate entering at 60c and leaving at 45c is used. r134a enters the evaporator at 20c, 15% dryness and exits as saturated steam at the same pressure. Since the compressor consumes 1.3 kW of power;evaporator pressure and mass a) evaporator pressure and mass flow of R134a b) heating load and COP value c) Calculate...

A Refrigeration System Using R-134A In a refrigeration system, the refrigerant R-134A begins as saturated vapor at -15°(State 1). It then goes through a reversible adiabatic compressor to reach State 2. After flowing through the condenser (a heat exchanger), the refrigerant exits as saturated liquid at 70°C (State 3). It is then throttled by going through an expansion valve, to reach State 4. It finishes the cycle by going through another heat exchanger (the evaporator), to return to State 1....

-Rome can get pretty hot in the mid-summer! Most of the air conditioning units in the Tiber campus use the working fluid R-134a (1,1,1,2-tetrafluoroethane), which is replaces the less environmentally-friendly R-12 of years ago. a) Illustrate the following air conditioning cycle, indicating material, heat, and work flows, as well as given/known temperatures and pressures: R-134a is pressurized to 10.2 bar in an adiabatic, reversible compressor. This high-pressure, hot refrigerant is condensed outside of the building using ambient air to a...

Problem I: Not applicable for 2017 Problem II: In an R-134a vapor-compression home heat pump, R-134A enters the compressor (75% isentropic efficiency) as a saturated vapor at 200 kPa and leaves at 800 kPa. The refrigerant goes through a constant pressure condenser and leaves as a saturated liquid. The refrigerant then goes through an adiabatic expansion valve enters the evaporator as a liquid-vapor mixture. The mass flow rate of refrigerant is 0.1 kg/s. and Cod A. Write the equation for...

QUESTION 4 (15 marks) Below is a schematic of a car air conditioning system that uses R-134a as its refrigerant. Here we will analyze the system under the case of driving through a very hot environment of 40 °C. The interior of the car is kept at 20 °C. Refrigerant leaves the compressor at 1.6 MPa absolute and leaves the condenser as a saturated liquid. The evaporator operates at 400 kPa absolute and the refrigerant leaves as a saturated vapour....

a) Company A designed a heat pump to
supply heat into a library in Canada during
winter, so that the library can maintain to be at 20°C. The heat
pump utilizes
