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, the 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. When the chiller selection of cold storage, priority higher 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. Multi-head screw chillers part load performance excellent refrigerator repair, can be selected according to the actual situation. 6. In the design selection should be noted: in the name of the traffic conditions, the outlet temperature of the cold water 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 the compressor is allowed, as with the main motor power is adequate. 1. Upgrading Diskless tube of pure stainless steel tanks, with a cooling effect lasting stability, temperature control accuracy of ± 1 ℃; 2, increases with high, low temperature display and signal output protection, configuration, normally open and normally closed output for choice; 3, upgrade frozen water system made of stainless steel multi-stage pumps and stainless steel, PVC material connection cold storage, no rust worries small refrigerator, can be directly used pure water or deionized water; 4, increasing water filters, providing high-quality laser precision work, increasing the water pressure indicator, easy to adjust pressure and flow, increasing with flow protection device, when the water flow is too low to automatically disconnect power laser machines, laser head due to lack of water to prevent overheating, increased electronic temperature control, dual digit display, a variety of settings and fault display function, just one key operation (open key), the other by the memory function automatically; 5, cooling capacity ranges: 102500Kcal / h to 654800Kcal / h.
