Product Detail

Product selection

1. the main control parameters of screw-type water chiller for cooling performance coefficients of rated cooling capacity and input power and type of refrigerant.

2. selection of chillers should be considered according to cooling load and use. For low load operating condition for a long time the refrigeration system, use head piston-type compressors or screw-type compressor, easy to adjust and save energy.

3. when selecting chillers, higher priority value of coefficient of performance of the unit. According to statistics, General chiller annual 100% load run time is about the total running time of 1/4. Total running time in the 100%, 75%, 50%, 25%-load running time scales roughly 2.3%, 41.5%, 46.1%, 10.1%. Therefore, the choice of comparison chillers should give priority to the efficiency curves of flat models. Also, should be considered in the design load adjustment range of chillers. Multi screw chiller part-load performance, can be selected according to the actual situation.

4. when selecting chillers, care should be taken on behalf of working conditions. Actual refrigerating effect of the chiller and the following factors:

A) cold water temperature and flow rate;

B) coefficient of cooling water temperature, flow and dirt.

5. when selecting chillers, should take note of the model of the normal working range of the unit is mainly motor current limit is the nominal operating conditions the shaft power of a current value.

6. should pay attention to in the design selection: under nominal operating conditions flow, cold water outlet temperature should not be more than 15 degrees, wind-cooling unit outdoor dry-bulb temperature should not exceed 43 degrees centigrade. Must be above this range, you should understand the use of compressors allow, equipped with main motor power is enough.
