Can you also show the T-S and P-H diagram? REF134A

A Single Stage Vapor Compression (SSVC) refrigeration system has a cooling capacity of 6 tons. The discharge of the evaporator is at -20°C & 0.1 MPa and the discharge of the condenser is at 30°C & 1.0 MPa. Determine the following: (a) the COP of the system, (b) the Energy Efficiency Ratio in kJ/hr/W, (c) the HP/ton of the system, (d) the Refrigerating Efficiency of the system.
