Magnetic Oil Free compressor

Active magnetic suspension bearings (AMB) and magnetic .bearingcontrol systems (MBC) are used.

Itisequippedwithpermanentmagnetsynchronous motorandwater-cooledvariable frequencydrive.The output is efficient and smooth,and the volume is only 5 0 % of the air-cooled inverter.

Extra ceramic bearing is equipped to protect the compressorfrompowerfailure.

Fully enclosed two-stage aluminum alloy impeller,which is stable and efficiency.

Activemagnetic suspension bearing

The magnetic suspension bearing works without friction, no energyloss,with long life-cycle.

Magnetic suspension bearings do not require lubricating oil,eliminatingthehassleoftraditionalbearingclock lubricants.

The magnetic suspension bearing works without friction, small vibration,and very lowsound levels.

Permanentmagnet synchronous

Permanent magnet synchronous technology,the power conversion rateisupto 9 7 %

Fullyoptimized for ultimate performance withanext generation low-GWP refreigerant,reliable operation andhighlyefficient,VFDstarting,startingcurrent only 2A,no impact on the power grid.

The PLC-VFD-MBC tripartite linkage,a complete negative feedbackclosed-loopcontrol system,realtime regulation of the output frequencyand voltage of the inverter circuit,to achieve precise control of the motor speed.

High efficiency evaporator

Therefrigerant entering theevaporator isspraying downward from theuppersideof the heat exchange tubearray,and the liquid refrigerant formsa filmflowing downward on the tube wall.Since onlya layer of liquid refrigerant film is coated on the surface of the heat exchange tube, the heat transfer effect isexcellent.

The shellis made of Q345R steel,the heat exchange copper tube isdouble-sided enhanced high-efficiency tube,and besides the heat exchange tube isavailableinvarious materialsand thicknesses.The distributor is made of stainlesssteel and is produced by self-owned CNC machine to ensure the quality of liquid distributor structure offalling film evaporator.

Itonlyneedsa smallamountofliquid refrigerant atthebottom ofevaporator,sotherefrigerant charge volume of the unit is small and meets environmentalprotectionrequirements.Therefrigerant vapordoes not need to be superheated,and the evaporation temperature can be greatlyimproved.

Highefficiencycondenser

The shell is made of Q345R steel,and the heat exchange copper tube is double-sided enhanced hi gh-efficiency tube, which isusedto condense the high-temperatureand highpressurerefrigerantintherefrigerationsystem into liquid, with certain degree of sub-cooling,as a result the chiller unit can operate efficiently and energy-efficiently.

The built-in liquid refrigerant separation device ensures that the liquid refrigerantaftercondensation is automatically separated from the heat exchange tube, ensuring sufficient contact between the heat exchange tube and the gaseous refrigerant,and greatly improving theheatexchange efficiency.of the copper tube.For large capacitychillerunits,this technologyisveryeffective, reducing thecondensationtemperaturebyabout1 ^ { \circ } \mathsf { C } ·

Economizer

Flash evaporator:The shellismade of Q345R steel.It uses the evaporationof therefrigerantof theunitto cool the liquid refrigerantafter the condenseris condensed,which increases the effect of sub-coolingand makes the unit run more efficientand energy-saving.

PlateType Economizer:SUS316L stainless steel.The Economizeradoptsasmallportionof therefrigerant evaporated by the expansion value after throtling,and togetherwiththemain refrigerantto be exchanged heat through the plate to reduce the temperature of the main refrigerant，therebyto increasetheeffectofsub-coolingto improve its energy efficient.
