Vivi dairy 50HP water-cooled screw chiller Dongxing screw chiller and screw chiller, screw type cold water machine, screw chiller, screw type refrigerating machine.
Screw type cold water machine because of its key components - screw compressor using named screw chiller, refrigerant evaporator units from out of the state for the gas compressor; after adiabatic compression, a high temperature and pressure. The gas refrigerant is compressed, in the condenser, isobaric cooling condensation, change into liquid refrigerant is condensed, and then expanded to low pressure through the throttle valve, gas-liquid mixture into. The liquid refrigerant in the evaporator is absorbed by the heat of the cold matter, and becomes a gaseous refrigerant. Gaseous refrigerant through the pipeline to re-enter the compressor, the beginning of a new cycle. This is the four process of the refrigeration cycle, and also the main working principle of the screw type water chiller.
Characteristics of screw type cold water machine of East star:
World famous brand compressor
Original imported twin screw compressor. Linear design of twin screw 5:6 teeth and advanced, energy efficient.
High efficiency valve energy control, to achieve grading or stepless energy control. Balance design, smooth operation.
Moving parts of the strict treatment, special exhaust oil balance block design, maintenance cycle is long, no fault running more than 40000 hours.
High efficiency oil separator, exhaust gas with an amount of less than 1.5%, and effectively improve the heat transfer of two, more energy saving and durable.
Novel high efficiency evaporator
Using the most efficient and efficient internal thread copper tube, enhanced heat transfer effect, more energy efficient.
The use of the latest CAD/CMA design and processing technology, CNC processing center production, compact structure, compact size, durable.
Heat exchange tube bundle with U type structure, can be drawn out for cleaning the whole internal scale, convenient maintenance.
Dry evaporator, easy to return oil, improve the life of the compressor and the reliability of the system.
Vivi dairy 50HP water-cooled screw chiller water cooled condenser
The use of the latest efficient external thread copper pipe production, heat, small size.
Using the latest CAD/CMA design and processing technology, with the production of CNC processing center completed, compact structure, high reliability.
Beautiful appearance, high efficiency and energy saving.
Air cooled condenser
Heat radiating fin is punched by high speed punching machine, and the quality of the film is reliable. Two flange, copper pipe is more close contact with the fin heat transfer efficiency.
Full import of copper pipe and automatic elbow welding, greatly enhance the oxygen density, to prevent leakage of refrigerant.
Especially suitable for the area of lack of water resources or high water hardness.
The micro processing control system vivi dairy 50HP water-cooled screw chiller
Centralized control of industrial PLC units, with the compressor's energy transfer system, can be timely and accurate control of the unit cooling capacity and the cooling load of the match, to ensure that the unit to run the best efficiency, reduce operating costs. The internal integration of water, low temperature, high pressure, antifreeze, phase delay start, reverse phase, overload, overheating, pressure difference of a number of safety protection and processing function. Full Chinese operation interface, menu style tips, can set the operating conditions of the unit, the operation environment of home appliances.
