A two-stage cascade refrigeration system operates between the pressure limits of 1.4MPa and 200 kPa with refrigerant-134a. The fluid leaves the condenser as a saturated liquid and is throttled to a flash chamber operating at 0.50 MPa. Part of the refrigerant evaporates in the flashing process, and this vapor is mixed with the refrigerant leaving the low-pressurin compressor. The liguid in the flash chamber iS throttled to the evaporator pressure and cools the refrigerated space. The mass flow rate of...

Eight (8) kilogram of saturated vapor of refrigerant R-134a is contained in a closed frictionless piston-cylinder device at a pressure of 200 kPa. Heat is then transferred to the refrigerant. At the end of the process, the refrigerant has a temperature of 70 °C. Determine the amount of heat that is transferred during the process. Also, show the process on a T-v diagram with respect to the saturated liquid and vapor lines. (35 points).

A refrigeration unit operates between pressure of 244.83 kPa and 1043.9 kPa, and uses refrigerant-22. The saturated vapour R-22 enters the compressor at -20 °C and leaves the condenser at 25 oC as a saturated liquid. Assume isentropic compression and neglect all losses. Use the property tables and/or figures in the text book. Calculate the coefficient of performance; and

Saturated liquid water at 10.0 MPa is throttled through a partially open valve (isenthalpic process) and...
Saturated liquid water at 10.0 MPa is throttled through a partially open valve (isenthalpic process) and discharged into a tank at a pressure 0.1 MPa adiabatically, aergonically, and without any change in its kinetic or potential energy. (NOTE: When the pressure on saturated liquid water is suddenly reduced in an adiabatic aergonic, steady flow process, part of the initial liquid is very quickly converted into a saturated vapor at the lower pressure, with the vaporization energy (heat of vaporization) coming...
