Under what circumstances are ammonia pipelines in liquid ammonia absorption refrigeration prone to frost?
Liquid ammonia pipelines need to be kept cold, otherwise they will be prone to frost.
Humid geographical environments are prone to frost or ice. There is usually frost when you wake up in the morning and it melts during the day. It is no problem to use cold storage. However, there are not many places for ammonia refrigeration and cold storage.
If the ammonia pipeline of liquid ammonia absorption refrigeration is prone to condensation in a place with a slightly higher temperature, it is easy to frost or freeze on valves or places with throttling. Therefore, the ammonia pipeline must be well kept cold.
It will happen when the temperature of the ammonia pipeline is lower than 0 degrees Celsius. In addition, it will also happen when the temperature difference between the interior and the atmosphere is generated (this is like gasification), absorbing heat.
