ZL type evaporating condenser
 

Lectotype method and program of equipment

1. Confirm total heat elimination for refrigeration system (corresponding refrigeration quantity of compressor + shaft power of corresponding working condition = total heat elimination quantity)

2. Confirm design condition: condensation temperature and local wet bulb temperature.

3. Choose proper coefficient from table 2 A or B and then confirm emendation coefficient.

4. Make total heat elimination quantity of system multiply emendation coefficient and then confirm emendation heat elimination quantity.

5. Choose evaporating condenser from table 1 and the standard heat elimination quantity should equal to or larger than emendation heat elimination quantity.

Notice: If refrigeration system adopts screw compressor, cooling water of oil condenser is gained by other methods that is: (when it doesn¡¯t use ZL series evaporating condenser), the emendation heat elimination calculated by the above method should detract heat quantity of oil cooler. And then, it can choose ZI series evaporating condenser from table 2.

Lectotype case:

Known: refrigerant R717 piston type compressor

Total heat elimination 961KW (the corresponding working condition heat elimination of compressor 750KW + corresponding working condition shaft power 211KW= total heat elimination 961KW)

Condensation temperature: 35¡æ

Wet bulb temperature: 23¡æ

Lectotype program:

It can get condensation temperature 35¡æ from table 2 B and the heat elimination coefficient of wet bulb temperature 23¡æ is 0.88.

Heat elimination ¡Á heat elimination coefficient = heat elimination load after correction

961KW¡Á0.88£½845.68KW

From table 1, it can choose ZL890 type evaporating condenser that can satisfy need
