he refrigerant R-134a enters the compressor of a refrigeration machine at a pressure of 140kPa and a temperature of -10°C, and exits at a pressure of 1MPa. The volumetric flow of the refrigerant entering the compressor is 0.23m3/minute. The refrigerant enters the throttling valve at a pressure of 0.95MP and at 30 °C, and exits the evaporator as saturated steam at -18 °C. The adiabatic efficiency of the compressor is 78%. Show the cycle in the T-s diagram. a) Power required to start the compressor b) Calculate the heat withdrawn from the cooled environment in unit time, COPSM=? c) Calculate how much the pressure of the refrigerant drops between the evaporator and the compressor and how much the heat gain is.
A commercial airliner is flying at an altitude where the temperature and pressure of the air are -50°C and 26.5 kPa. An engine-driven compressor will take this air at T= -50°C, P₁ = 26.5 kPa and compress it to P₂ = P₂ = 85.0 kPa to pressurize the cabin. The air will be very hot when it exits the compressor, so a heat exchanger will be used to cool the air to T, = 20°C before it enters the cabin. Cold air at T₁ = -50°C will be used in the heat exchanger to cool the cabin air, and this air will exit the heat exchanger at T = 20°C (this air will be used to heat the cargo bay). The mass flow rate of the air delivered to the cabin is 0.80 kg/s and the compressor efficiency is 75%. Model the air as an ideal gas having constant specific heat, using 300 K values from Cengel's tables posted on Canvas. a) Find the actual temperature of the air exiting the compressor and the power input to the compressor (answers: 67.6°C and 94.5 kW). b) Find the rate of heat transfer in the heat exchanger and…

A man purchases a turbine for use in his factory. He sets it up so that there is steam entering at 5000 kpa and at 873.15 Kelvin at a constant rate of 100 m/sec. This steam seems to leave the turbine at 100 m/sec and of 95% quality at a pressure of 0.01MPa. The manufacturer sticker claims the turbine has a power output known to be 56400 Joules per second. Find the theoretical mass flowrate of the steam through the device [kg/sec] and the area of the outlet [m^2]
An adiabatic capillary tube is used in some refrigeration systems to drop the pressure of the refrigerant from the condenser level to the evaporator level.
