In the condensation evaporator the liquid oxygen is heated to evaporate and the gas nitrogen is cooled and condensed. Both the liquid oxygen and the gas nitrogen are in a saturated state. If the saturation temperature of nitrogen is lower than the saturation temperature of oxygen at the same pressure, the purpose of condensing gas and nitrogen with liquid oxygen cannot be achieved. For this reason the heat transfer temperature difference in the condensing evaporator must be established by the pr...
