Screw Compressor Chiller

Screw Compressor Chiller

screw compressor chiller is a large industrial refrigeration equipment. It is a kind of chiller, widely used in central air-conditioning and large-scale refrigeration industry. It plays an important role in refrigeration, cooling and cooling. Using the working principle of water cycle to save water resources. Cool the device directly with cold water. It can prevent the temperature of industrial equipment from rising. Constant equipment low temperature state.

1. When choosing a screw compressor chiller, you should pay attention to the conditions of the nominal working conditions. The actual cooling capacity of the chiller is related to the following two points: a. The temperature and flow rate of the cold water outlet; b. The inlet temperature, flow rate and fouling coefficient of the cooling water.

2. The selection of screw compressor chiller should be considered according to the cooling load and the intended use. For the refrigeration system with low load and long working time, it is suitable to choose multi-head piston compressor unit or screw compressor unit, which is convenient for adjustment and energy saving. When the load changes, the screw compressor chiller will automatically determine the number of starts, so that the compressor is in a better working condition, thereby effectively saving electricity.

3. When selecting a screw compressor chiller, give priority to units with higher performance coefficients. According to previous data statistics, normal screw chillers run at 100% load throughout the year, accounting for less than 1/4 of their running time. The operating time ratios of 100%, 75%, 50%, and 25% loads are roughly 2.3%, 41.5%, 46.1%, and 10.1%. Therefore, when selecting a chiller, priority should be given to the screw chiller model with a relatively flat efficiency curve. At the same time, the adjustment range of the load of the chiller should be considered in the design and selection. The multi-head screw chiller has excellent partial load performance, and the screw compressor chiller can be selected according to the actual situation of the factory.

4. When choosing a screw compressor chiller, you should pay attention to the normal working range of this model, mainly because the current limit of the motor is the current value of the shaft power under the surface working condition.

5. When designing and selecting screw compressor chiller, attention should be paid to: under the nominal flow rate, the outlet temperature of the chilled water should not exceed 15°C, and the outdoor dry bulb temperature of the air-cooled unit should not exceed 43°C. If it exceeds the above range, check whether the range of use of the compressor is allowed and whether the power of the matching motor is sufficient.
