- Q.1. A refrigeration process with interstage cooling uses refrigerant HFC-134a, and the outlet of the condenser is to be saturated liquid at 40°C. Refer to the following figure for stream numbers in your solution. The pressure of the flash chamber and the intermediate pressure between compressors is to be 290 kPa. The evaporator is to operate at -20°C and the outlet is to be saturated vapor. The flowrate of stream 1 is 23 kg/h. The flash chamber may be considered adiabatic. The compressors may be considered to be 80% efficient. a) What is the power input required to the first compressor? b) What are the flowrates of streams 6 and 7? What is the enthalpy of stream 4?

Describe a typical ai Show transcribed image text2.6 2.39 J An industrial plant has available a 4 cylinder, 3 in bore by 4in. stroke, 800 rpm, single-acting compressor for use with R-134a - Proposed operating conditions for the comprassor are 100°F condensing temperature and 40°F evaporating temperature. It is estimated that the refrigerant will enter the expansion value as a saturated liquid that the vapor will leave the evaporator at temperature of 45°F and that vapor will enter the compressor at a temperature 55°F. Assumes a con volumetric efficiency of 70% and frictionless flow. Calculate the refrig- erating capacity in tons for a system equipped with this the cycle on the p-h diagram.

PlotOven Temperature 0 wwwwww Valve ↑y Steam B Piston Oil Supply H Working Cylinder Fig. Q3 Fig. Q3 shows an arrangement for controlling the temperature of a steam heated oven. utilizing temperature sensitive bellows and a hydraulic servomechanism. An increase in oven temperature causes the bellows to expand and the left end of the 'walking beam' ABC to move downwards. thus activating the hydraulic mechanism. The end C of the walking beam actuates a valve to reduce or increase the steam flow into the oven depending on the temperature in the oven. When .x is zero the beam ABC whose mid-point is B, is horizontal.

Assume saturated conditions for states 3, 4, 8, and 10. VI. Saturated steam at 0.2 MPa enters the generator and leaves as saturate water: Compute: a. the required mass flow rate of the steam (kg/hr) per kW of refrigeration produced b. the Heat Rejection Ratio, HRR = (Qabsorber + Qcondenser)/Qevaporator of the system.Create a Refrigeration Cycle Steps: You can start at an point in the cycle in the picture, but you must follow this order and you must make it through the entire cycle. The following must be included also and explained /defined Evaporation, Condensation, Fan for the Condenser and Blower for the evaporator. Provide good informationIn a basic LiBr-water machine, the generator operates at 170 F while the evaporator is at 47 F. the absorbing temperature is 75 F and the condensing temperature is 88 F.
