CSRAT-FC Series - Screw Freecooling

CSRAT - FC series Cooling capacity: 328KW～1600kW CLMAVENETA free cooling unit is an energy saving product developed for places requiring refrigeration all year round. Free cooling unit makes full use of the renewable energy outside the city air, gets free cold from low temperature air, reduces the operation time of compressor refrigeration, is a reliable, efficient, energy saving and water saving, green cooling products.

Extended Functions：

—B Standard uint -SL Super low noise unit -FC-NG No glycol FreeCooling unit -FC Standard FreeCooling unit

Frame Structure Description：

Base and frame in thick hot-galvanised shaped sheet steel. All parts polyesters-painted.

Compressor Description：

1, specially designed for HFC134a semi-closed twin screw compressor, high compression efficiency, can run efficiently under full load and partial load.
2, adopt high precision machining twin screw rotor, aviation rotary bearing, with stable performance, low noise, small vibration, smooth operation and so on.
3, the press built-in three high efficiency oil separator, even in the very high exhaust speed also ensure high oil separation effect, through improving the oil lubrication mode, effectively reduce the exhaust oil content and exhaust overheat, so as to further improve the oil separation effect.
4, with microcomputer control system, automatically adjust the load output according to the requirements of working conditions, stepless adjustment through the slide valve, improve part of the load performance.

Evaporator Description：

●Direct expansion heat exchanger type with asymmetric refrigerant paths to maintain the correct refrigerant velocity inside the tubes during both liquid and gaseous phases.
●The steel shell is insulated with a closed-cell anticondensation lining. The copper pipes are internally grooved so as to improve the heat exchange. The pipes are mechanically expanded onto the tube plate ends. An antifreeze electric heater prevents the formation of ice inside the casing of the exchanger when the unit is not operating but connected to the electrical supply. Differential pressure switch for controlling the water flow is fitted standard.
●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. The inverted M structure is adopted to increase the heat exchange area under the premise of constant unit volume; Uniform distribution of wind speed to achieve high performance heat exchange;
2, The design of the special cooling coil, the refrigerant coil and natural cooling coil organic combination, can maximize space savings, both compressor refrigeration or all natural cooling can meet the demand for cooling capacity.

Control Cabinet：

The optimal natural cooling pipeline program intelligent control is an effective way to save energy, Climaveneta air source natural cooling unit adopts advanced W3000 microcomputer intelligent control system, when the ambient temperature is lower than the return water temperature 2℃, the unit opens part of the natural cooling, Its unique adaptive function can intelligently adjust the compressor cooling amount according to the change of user water temperature and outdoor environment temperature, minimize the compressor work and maximize natural cooling on the premise of meeting the total cooling demand, and ensure the unit to run in the most energy saving way.

Control System：

● New generation regulation system with human-computer interface, better extended utility, supervision and compatibility.
● Panel screen on the unit, easy operation, better protection Microprocessor regulation fulfill human-free running.
● W3000 with LCD display, multi-language & multilevel menu for data display & set-point regulation .According to CLIMAVENETA tradition, another display of compressor’ working data is adopted for easy supervision.
● Dedicated W3000 microprocessor is inserted with CLIMAVENETA control algorithm to make sure energy saving and reliability.
● FIFO compressor running time balance function extends unit’ working life;
● Auto compressor power input control following with load change from 25-100% for energy saving;
● Environment adaptation by data regulation and setting;
● Modulating measurement is used for temperature pressure protection. It can increase reliability and predict fault occurs.
● Expansion kit for remote control and group control.
● Available in BMS control, such as ModBus, LonWorks, BacNet control system.
● Microprocessor have complete fault predict, alarm, record and self diagnose function assuring operation protection & working state.
● “Black Box” record 400 faults and 200 data before each fault, which diagnose & remove fault quickly
● We also can find potential fault and take preventive action before it occur by CLIMAVENETA remote service program

Certification and Honor：

Electric Control：

High Performance Fan：

※3d shaped fan blades are designed according to bionics and aerodynamics.
※Multi-blade design;
※ Intelligent control design, can automatically adjust the revolution according to the ambient temperature.

Low operating costs：

Since the compressor can not be run in winter, the use of natural cooling units can save up to 60% of the operating costs a year.

Total natural cooling at high ambient temperatures：

According to the climaveneta characteristics of most cities in northern China, the ambient temperature is relatively low most of the time. Climaveneta's latest natural cooling technology enables the unit to enter the full natural cooling state when the ambient temperature is lower than 2℃. When the ambient temperature rises, the unit will automatically adjust, without affecting the cooling capacity of the whole machine.
