Summary

Safety valves are used to guarantee refrigeration system safety under abnormal overpressure. For the safety valve of a CO2 refrigeration system, the tendency to form solid CO2 and to block the release path of the safety valve during release may endanger the entire system. This problem is unique for CO2 refrigeration systems and has never been studied before. In order to fill in the blank, the blockage characteristics of the different types of safety valves were experimentally studied by constructing glass tubes with different geometries similar to the flow channel in safety valves and building them into an experimental rig.
