Experimental Study on the Flow Condensation Heat Transfer of R290 and R22 in a Horizontal Circular Minitube

The condensation heat transfer characteristics of R290 and R22 were investigated experimentally in a horizontal circular minitube with 1.085 mm diameter. The mass flow rate of R22 is 200-1200 kg/(m2?s), and that of R290 is 200-650 kg/(m2?s). The saturation temperature is 40 ℃ and 50 ℃ respectively d...
