Pressure Vessel Introduction
Pressure vessel concept: A pressure vessel is a closed device that holds a gas or liquid and carries a certain pressure.
Pressure vessel for refrigeration unit:
The liquefied gas is used as a refrigerant, the design pressure is not higher than 4.0 MPA, and the container that is subjected to the refrigerant pressure in the refrigeration device having a design temperature of -19 to 200 degrees is called a pressure vessel for a refrigeration device. Specifically, it includes: a shell-and-tube condenser, a high-pressure liquid reservoir, a low-pressure circulation barrel, and the like having a inner diameter of 0.15 m or more and a volume of 0.025 m3 or more.
