Industrial Heat Exchanger Flooded Type

Shell and Tube Evaporator

The full-liquid shell-and-tube evaporator flows in the tube and the refrigerant evaporates outside the tube

tufts so that the heat transfer surface is substantially in contact with the liquid refrigerant. Generally, the

amount of refrigerant filled in the shell is about 55% to 65% of the effective volume of the cylinder. After

the refrigerant is vaporized and gasified, it is returned to the compressor by the liquid separator at the top

of the cylinder. The advantage is compact, easy operation and management, high heat transfer

coefficient.

The shortcomings are: ① refrigeration system evaporative temperature below 0 ℃, the tube water is easy

to freeze, destroy the evaporation tube; ② refrigerant charge; ③ by the height of the refrigerant column,

the bottom of the cylinder evaporation temperature is high, Will reduce the heat transfer temperature

difference; ④ evaporator cylinder will accumulate the bottom of the oil, there must be a reliable oil return

measures, or affect the safe operation of the system.

Dry type shell and tube type that is not full of liquid evaporator refrigerant flow in the tube, the water flow

outside the tube cluster. Refrigerant flow usually has several processes, due to the gradual gasification of

the refrigerant liquid, usually more upward, the more the number of process tubes. In order to increase

the water side of the heat transfer in the cylinder outside the heat transfer tube with a number of baffles,

so that the water several times across the tube flow. The advantages are: ① lubricants with refrigerant

into the compressor, generally there is no problem of oil accumulation ② filling less refrigerant, generally

only about 1/3 full liquid; ③ t0 near 0 ℃, the water will not freeze
