Operation procedure for liquid ammonia evaporator
Thread Content
Recently, I have a question: when using 12-degree chilled water as the pressure regulation medium for liquid ammonia vapor, how should the liquid ammonia evaporator be put into operation? Should the chilled water be introduced first, or should liquid ammonia be added first to establish the liquid level? If liquid ammonia is added first, could freezing occur when the chilled water is introduced?
Dude, your question isn’t quite clear. How can a liquid ammonia evaporator use chilled water as a \"pressure regulation medium\"? Do you use the evaporation of liquid ammonia to generate cold energy, thereby producing chilled water? If that is the case, it is recommended to establish a water circulation first, and then introduce liquid ammonia to set the liquid level. Otherwise, it is indeed possible to affect the chilled water (if there is water in the pipes or if the amount of water is very small!) ) It causes freezing and ice formation, thereby blocking the pipes.
Dude. . . Do you want to cool the liquid, or convert liquid ammonia into gaseous ammonia using vaporization? . . . 1. If ammonia vapor evaporates. . It is recommended to use steam or hot water. 2. If using liquid refrigerant, it is advised to first introduce liquid ammonia
We use liquid ammonia to produce gaseous ammonia, and then utilize the evaporation of ammonia to absorb energy from water at 12 degrees Celsius in order to generate chilled water at temperatures below 12 degrees Celsius; this achieves both the purpose of ammonia evaporation and the goal of saving energy and reducing consumption.
To prevent thermal shock, chilled water should be supplied first, after which the liquid ammonia evaporator establishes a liquid level.
