▲ Screw the main control parameters for the chiller cooling coefficient of performance, the rated cooling capacity, input power and the type of refrigerant.
▲ Chiller selection should be based on the cooling load and use to consider.Low-load operation conditions for longer periods of time cooling system,should use more head piston compressor or screw compressor, easy to adjust and energy.
▲ Selection of chillers, priority is given a higher coefficient of performance of the unit. According to statistics, the annual general chillers running at load, the total time to run time of 1/4 or less. The total running time of , 75%, 50%, 25% load ratio of the running time of roughly 2.3%, 41.5%, 46.1 %, 10.1 %. Therefore, the choice should be given priority chillers relatively flat efficiency curve models. Meanwhile, the selection should be considered in the design chiller load adjustment range. Multi-head screw chiller part-load performance, can be selected according to the actual situation.
▲ Selection of chillers, the state should pay attention to volunteers conditions.
Actual chiller cooling capacity with the following factors:
A) cold water temperature and flow;
