Independent refrigeration system, the design of the unit has multiple head to choose, the system is relatively independent, non-interference.

B. each refrigeration system compressor sequence start, single compressor in the minimum load (25%) under the star delta start, effectively reduce the starting current to reduce the impact on the grid.

Application of C. high efficiency refrigeration compressor

When the international famous brand 5:6 asymmetric double screw compressor, the compressor is the current international most advanced form of screw compressor, the moving parts of the reciprocating compressor is only 1/10, only for the vibration of reciprocating compressor 1/5, without fixed base. Radial and axial using a total of 11 high precision FAG Germany and Sweden SKF bearing combination, combined with the axial thrust balancing drum, effectively balance the axial load, the failure rate is only 1/10 of the reciprocating compressor, a control device and a world-class brand, a long period of time can ensure the unit safe and stable operation, has high energy efficiency ratio, service life (long service life for 100000 hours), low failure rate, easy maintenance and so on.

No single compressor can realize step and stepless control of energy regulation, flexible and convenient operation, energy saving and high efficiency.

This double three-dimensional oil separation filter, oil filter effect, effectively ensure the normal work of the compressor and the heat exchanger cleaning, the unit is always efficient heat.

Adopt no built-in pressure pump for lubricating oil system, energy saving, efficient and reliable.

This special fluoride resistant low loss of motor design, equipped with a motor overheating protection device is reliable, efficient and reliable work effectively to ensure that the motor.

Equipped with liquid refrigerant heat pump under the condition of no spray system, effectively reduce the key parts of the work load and working temperature, improve the working reliability of the compressor.

This patented exhaust chamber design and rotor continuous gas compressor, ensuring low vibration and low noise.

D. high reliability functional components

After the heat exchanger evaporator: efficient use of shell and tube heat exchanger, the use of imported sheet, internal heat exchange tubes by adopting internal thread copper tube type. The utility model has the advantages of high pressure rating, high heat exchange efficiency, no maintenance, long service life, etc.. The condenser is made of hydrophilic film, which has high efficiency of heat exchange, prevents the air from being blocked, and improves the corrosion resistance of the fin.

This control system adopts SIEMENS: unit control system. The use of advanced PLC control technology, can be programmed, and has a perfect communication function, can easily and intelligent building control system docking.

This unit uses electrical components, electrical system: SIEMENS, Schneider and other international brands.

This unit adopts the man-machine interface: SIEMENS touch LCD screen, in English man-machine interface, simple operation procedure, a key to start, automatic operation.

No other operation components such as expansion valves, solenoid valve, a dry filter, electrical components are imported famous brand, reliable quality, long service life.

Application of E. environmental protection refrigerant

Can use a variety of environmentally friendly refrigerants, such as R134a, R407C, R404A, etc., to meet the international environmental protection requirements.

F. unit enclosure

The unit adopts an integral design, the structure is compact and simple, retaining parts are automatic spraying equipment of electrostatic spray phosphating, strong corrosion resistance, with waterproof control cabinet, to ensure that the unit can be placed in long-term outdoor not easily fade, corrosion.
