2. Full Liquid Evaporator

■Optimized temperature field distribution and refrigerant flow field distribution, high heat exchange efficiency

■The outer fin design of the heat exchange tube enhances the vaporization core required for nucleate boiling and improves the heat exchange efficiency outside the tube.

■The inner ridge design of the heat exchanger increases the heat exchange area and heat exchange efficiency in the tube, increases disturbance, turns laminar flow into turbulent flow, and delays scaling.

■Unique tube bundle elastic support design greatly reduces vibration and eliminates the possibility of copper tube rupture

■Grooved tube plate hole design and advanced tube expansion technology provide a reliable sealing structure to avoid the problem of water penetrating into the evaporator shell.

3. Shell And Tube Condenser

■Optimized temperature field distribution and refrigerant flow field distribution, high heat exchange efficiency

■The outer fin design of the heat exchange tube enhances heat exchange and condensation and improves the heat exchange efficiency outside the tube.

■The inner ridge design of the heat exchanger increases the heat exchange area and heat exchange efficiency in the tube, increases disturbance, turns laminar flow into turbulent flow, and delays scaling.

■Unique tube bundle elastic support design greatly reduces vibration and eliminates the possibility of copper tube rupture

The grooved tube plate hole design and advanced tube expansion technology provide a reliable sealing structure and avoid the problem of water penetrating into the evaporator shell.

4. Advanced And Reliable Control System

■Flexible energy regulation control design enables the unit to track and adjust the energy output of the unit in real time according to changes in user load and environmental parameters, so that it can match the actual load to the maximum extent, so that the unit always operates at the highest efficiency point to save users operating costs to the greatest extent

■Internationally renowned brand electronic control components and microcomputer controllers monitor and ensure the optimal operation of the unit, and monitor the working conditions of sensors, relays and various switches connected to it.

■Large-screen LCD display, humanized operation interface, displays various operating parameters and fault diagnosis parameters of the control equipment

■High and low voltage protection, oil level protection, exhaust overheating, motor overheating, overcurrent protection, overvoltage alarm, undervoltage alarm, phase loss or reverse phase, water cutoff or low water flow protection, antifreeze protection and other automatic protection functions, functions Complete, ensuring high reliability of product operation

■It has control functions such as equal wear switching, accumulated running time record, fault display and locking, current temperature display, historical temperature trend and record, automatic start and stop, etc. It can also provide standard communication interface with remote control function according to user requirements (optional) configuration), ensuring a high degree of automation in product operation.

5. Double Compressor Design Of Large Cooling Capacity Unit

■Compressor backup function further improves unit operation reliability

■The compressor always runs in the high-efficiency section, further improving the unit's partial load efficiency.

6. Reliable Oil Management System

■The perfect use of built-in primary oil and external secondary oil in the compressor ensures efficient separation of refrigeration oil

■The complete oil return system ensures reliable suction oil return even under partial load.

7. Reliable And Complete Testing

■Strict air pressure and water pressure leak detection tests after assembly is completed.

■The flooded type shell and tube evaporator chiller has undergone a 12-hour air pressure holding test and a water system leak detection test.

■12h separate cavity pressure holding test for multi-system (including dual-system) chiller units.

■Comprehensive testing has been carried out before leaving the factory

8. Convenient For Transportation,Installation And Debugging

All flooded type chiller leave the factory with fluorine. After the equipment is installed, connect the water pipes and power cords, and press the start button to start the product.

It can be widely used in places that require air conditioning such as subways, shopping malls, hotels, theaters, hospitals, large factories, and high-rise buildings. It can also be used as an air conditioner for various industrial processes. Cold source host. Provide high-quality refrigeration and air-conditioning environment of 7°C to 12°C for its air-conditioning use or process.
