38 ph diagram of refrigeration cycle
Draw the cycle on a P-h diagram and determine: (a) B.P. of the compressor if Mech. efficiency is 75% (b) Bore and stroke of the cylinder if UD = 1.25 (c) Condenser water required for a temperature rise of 6°C. Solution: The various state points of the cycle shown in Fig. 36.26 may be obtained with the help of P-h chart as given below: P-H Diagram is to analysis the feasibility of the refrigeration cycle, to calculate the thermodynamic properties of the refrigeration system. Use the P-H Diagram analysis, all the refrigerant flow rates and operating conditions at the design point for the system can be clearly determined. (2) Refrigerant Flow Diagram.
