Overview

Product Name: Evaporative Screw Unit Product Overview: The "Shanglei" series evaporative condensing screw unit integrates various technologies such as evaporative condenser, full liquid evaporation technology, low-temperature refrigeration and pressure stabilization technology, multi-stage oil separation technology, etc. It is a perfect embodiment of Shanglei's years of technological accumulation. This series of units is widely used in central air conditioning projects in hotels, schools, shopping malls, office buildings, and other places. It can also be used for cooling projects in industrial production processes such as chemical, electronic, and precision instruments. With the implementation of energy-saving and emission reduction policies, this Shanglei series evaporative screw unit will be more favored. The unit has a compact structure, small footprint, simple pipeline design, no need for external water pipes, and easy installation and maintenance. Provide multiple protection functions such as high and low voltage protection, frozen water anti freezing and icing protection, power phase sequence protection, phase loss protection, insufficient water flow protection, compressor motor overheating, etc.

Product Details

a. Application of Full Liquid Refrigeration Compressor

◇ brand5:6Asymmetric twin-screw compressor, which is the current form of screw compressor, and its moving parts are reciprocating compressors1/10Vibration for reciprocating compressors1/5No need to fix the foundation. Radial and axial co use11Only high-precision GermanyFAGAnd SwedenSKFBearing combination, combined with axial thrust balance drum, balances axial load, with a failure rate of reciprocating compressor1/10By adding components, the unit can operate stably for a long period of time, with a high energy efficiency ratio and a long service life (operating life of)100000Hours), low failure rate、Easy maintenance, etc.

◇ A single compressor can achieve graded and stepless energy regulation, which is flexible, convenient, and energy-efficient in operation.

◇ The double-layer three-dimensional oil separation filter has good oil filtration effect, ensuring the normal operation of the compressor and the cleanliness of the heat exchanger, so that the unit is always in heat exchange.

◇ Adopting a pump free built-in pressure differential lubrication system, energy-saving and reliable.

◇ Fluorine resistant and low loss motor design, equipped with reliable motor overheating protection device to ensure reliable operation of the motor.

◇ The design of the exhaust chamber and continuous gas supply to the rotor ensure low vibration and low noise of the compressor.

d.Reliable functional components

◇ Full liquid evaporator: The unit adopts full liquid evaporation technology, which improves the heat transfer efficiency compared to traditional dry evaporators3More than twice, the energy efficiency of the unit is improved compared to traditional dry evaporator systems14%.

◇ Evaporative condenser: The condensation heat of the refrigerant is directly discharged to the outdoor air without the need for an external cooling water system. The condenser temperature of the unit can be reduced compared to traditional chillers4Around the degree, the energy efficiency ratio can be improved12%Colleagues also save on cooling water pumps and towers.

◇ System: The unit adopts Siemens system. usePLCTechnology, capable of accepting programming, and equipped with comprehensive communication functions, can easily integrate with building intelligent systems.

◇ Electrical system: The unit uses electrical components from brands such as Siemens and Schneider.

◇ Human machine interface: The unit adopts Siemens touch LCD display screen, with Chinese and English human-machine interface, simple operation program, one click start, and automatic operation.

◇ Other operating components such as expansion valves, solenoid valves, drying filters, electrical components, etc. are all imported brands with reliable quality and long service life.

e.Application of refrigerants

Multiple refrigerants can be used, such asR134a,R407C,R404AWaiting to meet social demands.

◇ Stability: "Shanglei" integrates global supplier resources to order each component of the unit, ensuring the high quality of each component and thus ensuring the stability of the overall quality of the machine.

◇ Energy saving: The unit adopts the Siemens complete system, equipped with the unit energy-saving program independently developed by "Shanglei", to ensure that the unit automatically adjusts the operation status of the compressor according to the set working conditions, greatly ensuring smooth and energy-saving operation of the unit.

◇ Simplicity: The unit structure is simple and has a good human-machine interface. Within the operating range of the unit, the operating conditions of the unit can be freely set. Once set, the unit can operate on its own and adjust its energy in real time, making it easy to operate.
