Refrigeration Industry Water Cooling

Flooded Type Evaporator

The "full liquid" refers to the unit used in the "shell and tube evaporator" using a "full liquid evaporator" in

the form, which is different from the "dry", "falling film" of a shell and tube Evaporator.

Its "shell" inside the refrigerant cycle, "pipe" to take the chilled water cycle, from the profile point of view,

as if there are half of the cylinder tube refrigerant, and the water pipe bundle soaked in the refrigerant. It

is the opposite of the "dry evaporator", dry type is "pipe" to take the refrigerant, "shell" water, like the

refrigerant tube soaked in water.

Full-liquid evaporator, and full-liquid unit, than the dry evaporator / dry unit heat transfer efficiency is

higher, the water temperature and the temperature difference between the temperature difference is

small, along the resistance is small, suitable for large circulation Of the unit (such as centrifuges), cooling

effect is good.

But the refrigerant charge requirements, and the need for a dedicated oil return system to help the

compressor back to the oil.
