01. A refrigerant 22 system having a refrigerating capacity of 55 kW operates with an evaporating temperature of 5°C and rejects heat to water cooled condenser. The compressor is hermetically sealed. The condenser has a U value of 450 W/m².K and a heat-transfer area of 18 m? and receives a flow rate of cooling water of 3.2 kg/s at a temperature of 30°C. What is the condensing temperature?
