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. The selection of chilled water cooled chiller unit, 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 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. Details: water Guiji is a source of cooling water for the cold to take the cold refrigerant system central air conditioning unit, the structure will compressor, evaporator, condenser, throttling parts and other foreign direct output into one centralized air-conditioning. Water Guiji water as a coolant condenser shell and tube heat exchanger effectively improve the efficiency of water and refrigerant heat exchanger, a substantial increase in energy efficiency, highlighting its cooling effect. Water Guiji usually applied to hot summers and space requirements large amount of wind sites; water Guiji demand selection can be used alone or more centralized control in a controlled manner in accordance with the customer. Water Guiji wide range of applications, suitable for shopping malls, hotels industrial chiller, factories, villas, commercial housing Carrier chiller, offices, shops, hospitals and other places. Product Specifications: 1HP - 90HP. ◆ water Guiji standard built-in circulation pumps, cooling tower interlock control contacts. ◆ water Guiji most models using multi refrigeration loop system can be up to six energy regulation at part load more energy industrial chiller chilled water machine wanjiang _ _ Xuelong Industrial chilled water cooling machine from Dongguan City Xuelong Refrigeration Electrical Equipment Engineering Co., Ltd. to provide.
