High-Efficiency Water-Cooled Chillers For Industrial Process Cooling

High-Efficiency Water-Cooled Chillers for Industrial Process Cooling

HIGH EFFICIENCY COMPRESSOR
High-Efficiency Twin-Screw Compressor
Features segmented or stepless capacity modulation, allowing the compressor to adjust output based on process temperaturerequirements-maximizing energy efficiency.The semihermetic design eliminates the need for shaft seals, resolving leakage issues and improving overall reliabiity. The motor isseparately housed from the compressor body, making maintenance and servicing easier.Incorporates the latest asymmetric rotor profle, with a 5-obe male rotor and 6-lobe female rotor. These are precision-ground using specialhigh-accuracy grinding machines to ensure optimal tooth clearance and maintain high volumetric eficiency even under continuousoperation.
Equipped with a high-eficiency, sealed motor that is fluorine-resistant, energy-efficient, and highly reliable. The direct-drive desigr
eliminates the need for a transmission shaft, ensuring minimal energy loss and high mechanical efficiency.

Discharge Port: Equipped with a check valve to prevent reverse rotation of the compressor during shutdownElectronic Protection Module: Realtime monitoring of discharge temperature, motor temperature, and voltage; protects the
compressor during abnormal operation.
Semi-Hermetic Desiqn: No shaft seal leakage issues. The motor and body are separately desianed for easier maintenanceCapacity Control Valve: Supports either stepped or stepless capacity regulation.
Built-in High-Eficiency Oil Separator: ntearated ductile iron construction reduces noise by 50%, Uses high-precision filtermesh with oil separation eficiency up to 99.79%, ensuring proper oil levels in the compressor and improving evaporator healexchange efficiency.
Twin Screw Rotors: Latest asymmetric tooth profle with minimal inter-tooth pressure diference and backflow ports, resulting in high volumetric efficiency.
Direct Drive Motor: No energy loss from mechanical transmission, high efficiency, low-speed compressor operation, and low noise.
High-Precision Bearings: lmported high-precision bearings from FAG (Germany) and SKF (Sweden).
US LEESON Motor: High-efficiency, oxygen-resistant sealed motor with refrigerant cooling, minimizing heat emission and improving energy efficiency.
Suction port: Eauipped with a suction shut-off valve, allowing compressor maintenance without refrigerant recovery.
Oil Filter: Ensures clean lubricating oil to prevent clogging of key components such as the electronic expansion valve. Easy to disassemble and clean.

THE CONDENSER
High-Efficiency Condenser
Featuring a pin-type structural design for thin liquid film and low thermal resistance.

Equipped with a refrigerant distributor to ensure even flow without dead zones.

Advanced tube arrangementechnology delivers high heat transfer efficiency.

Multi-stage subcooling design in the subcooling zone significantly enhances the unit's overall energy eficiency.

THE EVAPORATOR
High-Efficiency Evaporator
The high-efficiency evaporator ensures uniform refrigerant distribution.It uses dedicated falling-film heat exchange tubes to improve heat transfer efficiency and reduce refrigerant chargeAdvanced CFD fluid simulation analysis is applied to select the optimal design for superior heat exchangeperformance.
Equipped with a two-stage liquid distrilbutor for uniform distribution, while the evaporator outlet features a suctionbaffle design to effectively prevent liquid carryover into the compressor.The uneven tube group partitioning technology ensures stable heat transfer.An independent oil return port is designed to ensure effective oil return under full load conditions.
