Product Name: Water-cooled screw chiller Uses: 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 at low load operating conditions of the refrigeration system, should use multi-head piston compressors or screw-type compressors, easy to adjust and energy. The main control parameters 2. screw chillers for cooling coefficient of performance water-cooler, rated cooling capacity, input power and refrigerant type. 3. The selection of chillers, should pay attention to the normal operating range of the model units, mainly the main motor current limit is the current value of the nominal operating conditions of shaft power. 4. The selection of chillers, should pay attention to the conditions of the nominal operating conditions. The actual cooling capacity chiller with the following factors: 1) the cold water temperature and flow; 2) cooling water inlet temperature, flow and fouling factor. 5. The selection of chillers, the priority to high coefficient of performance of the unit. According to statistics, the annual general chillers run at 100% load time accounts for less than 1/4 of the total running time. The total running time in the 100%, 75%, 50%, the proportion of the running time is approximately 25% of the load of 2.3%, 41.5%, 46.1%, 10.1%. Therefore, the choice should be the priority chiller efficiency curve is relatively flat models. Meanwhile, in the design selection should consider the adjustment 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 chilled water flow condition room for air-conditioning, cold water outlet temperature should not exceed 16 ℃, air-cooled unit outdoor dry bulb temperature should not exceed 42 ℃. If the chiller selection must be more than the above range, you should understand the use of the compressor is allowed, as with the main motor power is adequate. Common classification chiller in the industry is divided into air-cooled chiller and water chillers are two, on the chiller temperature control is divided into low temperature chiller and chiller room temperature, room temperature control in the range of 0 degrees -35 degrees inside. Cryogenic temperature control is generally at 0 degrees - about minus 120 degrees range. (On the market in addition to the chiller call, there are such as: freezers, industrial chillers, industrial freezers, chillers, low temperature chillers, low temperature freezers, screw chillers, screw chillers, water cooled screw chillers, water cooled screw chillers, air-cooled chiller, air-cooled chillers, low temperature brine chillers, brine freezing units, water-cooled screw chillers, water cooled screw chiller, screw chillers, air-cooled screw chillers, air-cooled screw chillers, water cooled screw unit, etc. Here collectively chiller.)
