The following properties for Freon-12 were obtained. At -22 °C h (superheat) = 353 KJ/kg ha = 343 KJ/kg %3D At 44 °C h (superheat) = 300 KJ/kg h (subcooled) = 228 KJ/kg h = 238 KJ/kg %3D %3D Vapor Compression Refrigeration system with Heat Exchanger uses Freon-12. Liquid refrigerant leaves the condenser at 44 °C. The evaporator Temperature is -22°C. The internal heat exchanger temperature is 30°C. Compute for the cooling effect in KJ/kg.
