In an ammonia refrigeration system where the evaporator is of the shell-and-tube type, are baffle plates necessary in the shell side?
As needed, baffles offer higher efficiency
There is no need for it; the evaporator undergoes heat absorption during phase change, and the gas phase has little effect on heat exchange, so adding baffles is pointless
Support plates should be installed in the shell side, but no baffle plates.
If baffles are installed, turbulence should increase in theory, which can improve heat transfer efficiency; however, it will also increase pressure loss. The specific effects of these changes still need to be confirmed
No baffle plates are needed; support plates are required
I came across one before that had no design
If it is a dry type, baffles are required; if it is a full-liquid type, support plates are sufficient.
