Shanghai screw chiller, screw chiller

Shanghai screw chiller, screw chiller Shanghai screw chiller is named after its compressor. Compared with scroll chillers, its energy efficiency ratio is higher. Under the same power consumption, its cooling capacity is also high. For scroll chillers, it is widely used in markets with large cooling capacity requirements.
Working principle of Shanghai screw chiller:
The refrigerant coming out of the evaporator of the screw chiller is gas refrigerant , after adiabatic compression by the compressor, it becomes a high-temperature and high-pressure state, enters the condenser for medium-pressure cooling and condensation, and changes into a liquid refrigerant after condensation, and then expands to low pressure through the throttle valve and becomes a gas-liquid mixture, in which the refrigerant at low temperature and low pressure The liquid refrigerant absorbs the heat of the cooled substance in the evaporator and becomes a gaseous refrigerant again. The gaseous refrigerant re-enters the compressor through the pipeline and starts a new cycle. The generation of chilled water is completed in the evaporator.
Features of Shanghai screw chiller:
The compressor adopts an international brand, a new high-efficiency spiral rotor compressor, which is %% more efficient than ordinary compressors, and has obtained patents and international quality certifications from many European and American countries.
.High efficiency control: patented asymmetric rotor tooth profile.
.Capacity control can adopt four-stage (%%%%) or three-stage (%%) and stepless control systems.
. It adopts high-efficiency silicon steel and special groove design, and is equipped with internal and external omnidirectional cooling flow channels, so that the compressor motor can achieve maximum efficiency under any load.
Unique built-in hydraulic system, no need for The oil pump also ensures that the compressor maintains the best lubrication effect.
The oil separator adopts a double-layer filtration method, which has good oil filtering effect and the heat exchanger can exert its maximum capacity.
.High efficiency, low noise, low noise Vibration.
The system is equipped with motor overload, short circuit protection, overheating, high pressure, low pressure, compressor delayed start protection, water flow protection and other functions. The unit operates safely and reliably.
Shanghai screw chiller microprocessor The control system uses centralized control of industrial-grade units, and cooperates with the energy regulation system of the compressor to accurately control the matching of the unit's cooling capacity and cooling load in a timely manner, ensuring that the unit operates at optimal efficiency and reducing operating costs. Balanced design. Ultra-quiet and smooth operation. Strict handling of components, special oil balance block design at the exhaust, long maintenance cycle, and more than hours of trouble-free operation.
