How to identify superheated refrigerant
WebIf liquid and gas States refrigerant are both present in one place, refrigerant on the saturation temperature. If liquid is present, may be on the saturation temperature (saturated liquid), or it may be below the saturation temperature (supercooled liquid). WebGiven, pipe diameter, d = 0.06 m flow velocity, v = 45.6 m/s at the steady state of inlet condition of 50C, 450 kPa steam is superheated here From refrigerant tables, inlet specific enthalpy, h 1 = 293 kJ/kg inlet refrigerant density, ρ = 18.4 kg/m 3 at the steady state of exit condition of 60C, 220 kPa steam is superheated here
