Abstract: | With good performance under variable conditions, longer service life, smaller size and higher volumatric efficiency, the water cooling screw chiller units are widely used in the range of middle refrigerating capacity. Analyses the influences of refrigerants (R22,R134a), nominal working condition and fouling factor on performance of the units, which provide helps for selecting and adopting the units. |
