CSRAT Series Cooling capacity: 120～1460kW The air-cooled chiller is a central air-conditioning unit that uses air as the cold source and water as the cooling medium to meet the annual cooling needs of buildings or process systems. The unit can be directly installed on the roof or outdoor space, without special machine room, without cooling tower, cooling water pump and cooling water pipeline system. The whole system has simple structure and convenient application, and can be widely used in shopping malls, hospitals, hotels, factories, office buildings, etc. Air-cooled chillers include standard chillers ，partial heat recovery and total heat recovery.Using brine or glycol solution, the unit can also output -8～12℃ ℃ process cold water to meet the needs of process air conditioning and process cooling.

Extended Functions：

-D partial heat recovery -R total heat recovery -B Standard uint -HT High temperature uint -LN Low noise unit -SL Super low noise unit

Frame Structure Description：

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

Compressor Description：

● Screw: The semi-hermetic twin-screw compressor not only runs smoothly, but also has a precise compressor rotor gap, which minimizes the leakage on the high and low pressure sides, thereby improving the compressor efficiency and having a high COP value.
● Rotating bearing: aviation-grade bearing, strong and wear-resistant. By optimizing the torque distribution and reducing the front and rear pressure difference, the axial torque and radial torque are reduced at the same time, the bearing force is improved, and the service life is effectively prolonged.
● Oil separator: The compressor has a built-in three-stage high-efficiency oil separator, which ensures a very high oil separation effect even at a very high exhaust speed. By improving the oil supply and lubrication method, the exhaust oil content and exhaust gas are effectively reduced. degree of superheat, thereby further improving the oil separation effect.
● Stepless adjustment: The energy control through the slide valve can make the cooling capacity stepless adjustment in the range of 10%～100%.

  

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 GB150 steel pressure vessels and JB/4765 pressure vessels for refrigeration devices.

         

Condenser：

●The inverted M-shaped structure is adopted to increase the heat exchange area on the premise of constant unit volume; Uniform wind speed distribution, high-performance heat exchange, reduced frosting time during heating, and improved heating and defrosting performance;
● With corrugated sheet design, the condenser of the unit is not easy to be blocked, the maintenance cost of the unit is reduced and the service life is longer; The aluminum sheet adopts thickened design, which is not easy to collapse;
●The air-cooled condenser adopts the secondary refrigerant circuit technology, which is composed of copper tubes passing through aluminum fins. The end of the condenser is connected with the auxiliary refrigeration circuit, so that the refrigerant is in a subcooled state, and an inner threaded pipe is used to increase the heat exchange area and the disturbance of the refrigerant.

Control Cabinet：

●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.
● 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.
● 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：

● 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
