The selection of evaporator type is determined according to the requirements of cooling object and cooling mode. In the condition of guaranteeing the quality and quantity of the product, the selection of evaporator requires safe and reliable operation, economic efficiency, energy saving, labor saving and labor intensity reduction. In general, the following principles can be selected:

1., cooling rooms, freezing rooms and refrigerated refrigerated rooms in cold storage should be used in a cooling fan.

2. freezing tray, container or small package food can be used as overhead pipe or flat freezer.

3., freezing wall should be used for freezing and top row pipes. When food is well packaged, a dry breeze cooling fan can be selected.

4. when the room temperature is less than one or 0.5 degrees, the evaporation pipe should be selected. If the room temperature is higher than one or 0.5 degrees, the cold fan should be adopted.

5., the refrigerated cargo compartment on the refrigerated ship should be smoothed with top row. If there is a smooth wall, the anti-collision device is needed.

6. when the indirect cooling system is used on refrigerated vessels, horizontal shell and tube evaporators can be selected.

The net building height of the 7. ice warehouse is below 6m, only with a smooth top row and arrangement, without wall pipe. If the building is high, the smooth wall can be arranged at above 6ri, but it should be installed above the height of the ice.

The vertical tube and coil type evaporator spiral tube, 8. ice and cold water tank.

9. in the air conditioning system, can be selected according to the shell and tube evaporator or in wet and dry type, mixed type air cooler process requirements
