Refrigerant 134a is used in a cooling system operating according to the ideal cooling cycle with vapor compression for cooling the cold storage in the milk processing plant. The flow rate of the refrigerant is 0.10 kg/s. The condenser and evaporator pressures are 1000 kPa and 600 kPa, respectively. a) Calculate the cooling capacity as (kW). b) Calculate the volumetric flow rate of the refrigerant at the compressor inlet. c) Calculate the efficiency coefficient of the cooling system.
