Thermal energy storage with chemical reaction of NaINH 3 system—I. Region of liquid phase

A liquid phase in the reaction of solid sodium iodide with gaseous ammonia offers a method of thermal energy storage at temperatures for air-conditioning. Although the maximum temperature where the solid ammoniate exists, is around 31°C under 2.7 kg/cm 2 ammonia pressure, a considerably wide range of liquid phase can be used for storage of thermal energy. In addition to that, the liquid region extends to temperatures below zero under higher pressure than atmosphere. The density of the liquid ammoniate varies depending on temperature and ammonia pressure, but the maximum value observed in the present experiments was 1.7 g/cm 3.
