Latent heat of condensation – water at 0.1 MPa (atmospheric pressure)
hlg = – 2257 kJ/kg
Latent heat of condensation – water at 3 MPa
hlg = – 1795 kJ/kg
Latent heat of condensation – water at 16 MPa (pressure inside a pressurizer)
hlg = – 931 kJ/kg
The heat of condensation diminishes with increasing pressure, while the boiling point increases. It vanishes completely at a certain point called the critical point. Above the critical point, the liquid and vapor phases are indistinguishable, and the substance is called a supercritical fluid.
The heat of condensation is the heat released to completely condendse a unit of saturated vapor and it equal to – hlg =hl – hg.
The heat that is necessary to melt (or freeze) a unit mass at the substance at constant pressure is the heat of fusion and is equal to hsl = hl − hs, where hs is the enthalpy of saturated solid and hl is the enthalpy of saturated liquid.
