Functions：
1-Oil Free Centrifugal Compressor 2- Refrigerant R134a 3-Cooling
Frame Structure Description：
1.Floor adopts outer surface of the unit has been doing polyester spraying process of galvanized steel plate, make the whole unit should not be rust.
2.Convenient, compact structure, simple unit.Easy to fully grasp the running state of unit, the evaporator and condenser in the process of transportation, room installation and daily operation effective protection effect and make the maintenance more convenient.Units inside decorate after three dimensional optimization design, layout is compact, the optimized shape proportion, need to the maintenance of the space is little, take up room area is small, save space.
Compressor Description：
1.Inverter driven high-efficiency magnetic levitation oil-free compressor: the compressor is designed with aerodynamic optimized two-stage centrifugal and magnetic levitation technology, high performance pulse width modulator (PWM), automatic regulation of rotation speed, which promise optimal operation and high-efficiency under both full load and part load operation.
2.A significant improvement(15%) in the heat exchange can be achieved by magnetic levitation technology without oil lubrication system, contact friction and the thermal resistance caused by oil film.The reliability of unit is remarkably improved in the meanwhile and makes service convenient.
3. With build-in inverter, which enables variable motor speed of compressor under part load condition, the units are able to operate effectively and with lower power consumption. Soft start-up function makes the starting current of unit low to 2A, therefore to reduce impulse on power network and decease
thermal stress of motor stator.
Evaporator Description：
1.With the shell and tube type flooded type structure design, the refrigerant can fully evaporate, improves the thermal efficiency in.
2.High heat transfer efficiency of spirals inside thread copper pipe, increase the heat exchange area and refrigerant disturbance, improve the effect of heat transfer.
3.The design, manufacture and inspection of the evaporator comply with national standards and regulations for pressure vessels such as GB / 150 steel pressure vessels and JB / 4765 pressure vessels for refrigeration devices.
Condenser：
1.Shell and tube heat exchanger with efficient double thread copper pipe, increases the shell side between the refrigerant and cooling water tube side heat transfer effect.
2.Condenser uses the unique way of admission, uniform distribution of refrigerant flow, extend the condensation distance, make the heat transfer effect is best.Also increase the degree of supercooling unit, which can effectively improve the efficiency of unit cycle.
3.The design, manufacture and inspection of the evaporator comply with national standards and regulations for pressure vessels such as GB / 150 steel pressure vessels and JB / 4765 pressure vessels for refrigeration devices.
Control Cabinet：
1.The unit startup and microcomputer control parts are integrated into the same control cabinet and located at the front of the unit, which is convenient for the on-site operators to operate in the machine room and between the units. The maintenance of all electrical parts can be carried out at the front of the unit.
2.The electrical control box is made of high-quality steel plate, and the external surface has been galvanized and anti-corrosion treatment, which can effectively protect the electrical components of the unit.
3. For the safety of the operator, once the host is powered on, the operator will not be able to open the isolation board between the control and electrical components to ensure the safety of the operator.
Control System：
1.Friendly Interface :Screen embedded in the unit operation, convenient operation, good protection.Full computer automatic control, realizes the unmanned operation.Intuitive interface, LCD multilingual menu display data and parameter adjustment, in accordance with the traditional clement, press condition and parameter has a separate visual display, running status be clear at a glance.
2.Unit Control and Operation Management:The advanced microcomputer intelligent control system of W3000 contains specially designed control algorithm of Climaveneta. It highlights the energy efficiency and reliability of the unit. The balanced running time of FIFO compressor prolongs the life of machine. The automatic adjustment of the output load makes the machine more energy saving. Combining with the load shedding system of the compressor, 25-100% stepless adjustment can be achieved and settings of the operating parameters can be adjusted, which is adaptable to different environments. The temperature and pressure protection using analog measurement can predict and prevent failure and increase reliability. Various expansion accessories are available, such as remote and group control.
3.The chiller supports BMS connection and can provide MODBUS, LONWORKS, BACNET communication protocols with RS485 serial interface.
4.FWS Internet web server: microcomputer intelligent controller can be equipped with clement FWS web server, via LAN or Internet network monitoring, parameter setting and adjustment and control the operation of unit.
Electronic Expansion Valve(EXV)：
The electronic valve is adopted to grant the ideal operation of
the evaporator in all conditions.The fast processing of the acquired data allows a quick, fluctuation-free regulation, and therefore a highly accurate adjustment to the swings of load and ambient conditions.
Excellent Part Load Performance：
With magnetic levitation compressor, variable frequency inverter control and oil free lubrication system, the unit has boosted with 60% of ESEER to compare with traditional chiller and less service cost. High speed of compressor running, while with no mechanical contact of bearing, enables super-low noise and vibration of compressor under both part load and full load.
