Product Name: Water-cooled screw chiller Usage: used in electronics, plastics, pharmaceuticals, metallurgy, etc., can increase productivity! Scope: central air conditioning system or large industrial refrigeration Details: 1. chiller selection should be based on the cooling load and use to consider. For a long time the low load operating conditions of the refrigeration system, should use multi-head piston compressor or screw compressor, easy to adjust and energy. 2. The main control parameters screw chillers for cooling coefficient of performance, rated cooling capacity, input power and refrigerant type. 3. Use chillers, you should pay attention to the normal operating range of the model water-cooled chiller units, mainly the main motor current limit is the current value of the nominal operating conditions of shaft power. 4. Selection chillers, you should pay attention to the conditions of the nominal operating conditions. The actual cooling capacity chiller with the following factors: 1) cold water temperature and flow; 2) cooling water inlet temperature, flow and fouling factor. 5. The selection of chillers, the priority higher coefficient of performance units. According to statistics, the annual general chillers run at 100% load time accounted for less than 1/4 of the total running time. The total running time of 100%, 75%, 50%, 25% load run time ratio of approximately 2.3%, 41.5%, 46.1%, 10.1%. Therefore, the choice should be given priority chiller efficiency curve is relatively flat models. Meanwhile, in the design selection should consider adjusting range chiller load. Part load performance multi-head screw chillers good, can be selected according to the actual situation. 6. In the design selection should be noted: In the name of the traffic conditions, the cold water outlet temperature should not exceed 16 ℃, air-cooled unit outdoor dry bulb temperature should not exceed 42 ℃. If the need exceeds the above range, you should understand the use of range of the compressor is allowed, the main motor with power is adequate. 1, compressor chiller system of industrial chiller, refrigeration compressor power is guaranteed by the compressor to increase the water pressure of the refrigerant system chilled water machine, the refrigerant circulating in the refrigeration system chilled water machine, reach refrigeration purposes. Compressor according to their structure is divided into three categories: open, semi-enclosed, fully enclosed. Currently the majority of industrial chillers 0 ℃ above freezing water chillers are fully enclosed compressor, freezing water below 0 ℃ low temperature chillers are based on semi-hermetic compressors (common with screw and reciprocating) while open chiller is generally used in refrigerants ammonia refrigeration system.
