Screw chiller is a chiller which made for various screw compressors as the main engine. Feizhong water screw chiller is selected imported famous brand semi-hermetic screw. Double-screw 5:6 ratio and advanced linear design, low carbon, save energy and environmental protection; good performance, low noise. According to customers' needs and cooling capacity, a single compressor or a combination of multiple compressors is used. The compressor can automatically run alternately according to load change, and balance the running hours of each compressor, which greatly prolongs the chiller working life, and the trouble-free operation can reach more than 48,000 hours.

 

Feizhong screw water chiller with cooling capacity range from 100kW(8.6*10⁴kcal/h) to 1964kW(168.8*10⁴kcal/h), It is widely used in shopping malls, hotels, theatres, hospitals, and large factories and high buildings and other places that require air conditioning or ice storage and can be used as cold source host for processes in electric power, chemical, pharmaceutical and other industries as well.

Performance Advantages

 

 

Simple structure, fewer moving parts, fewer consumables parts and long working life.

Running smoothly, no "surge" phenomenon during low-load running..

High compression ratio and high EER value.

Adjusted steplessly within the range of 10%~100%, and the efficiency is high at partial load, and save power is remarkable.

No sensitivity to wet stroke

Structural Feature
 

1. Leading Design Concept

(1) This water cooled screw compressor chiller has an independent refrigeration system design, the multi-head unit is relatively independent, the moving parts are minimized, and the operation is reliable;

(2) Imported high-efficiency economizer-type semi-hermetic twin-screw refrigeration compressor is adopted which has a high energy efficiency ratio, reliable operation and long working life;

(3) The dual-cycle coupling refrigeration method with energy-enhancing energy saver is adopted to improve the working capacity and energy-saving efficiency of the unit;

(4) Use international brand thermal expansion valve, solenoid valve, check valve and other control components to ensure that the unit is in a variety of conditions of efficient and reliable operation.

2. Reasonable Energy Control

(1) Under the minimum load (25%), the compressors of each refrigeration system start with star-delta step-down, which reduces the starting electric current and the impact on the power grid effectively ;

(2) Flexible energy adjustment can make the unit adjust the energy between 25% and 100% (step-less energy adjustment) continuously, ensuring the compressor performance to full play, helping customers save running costs to the greatest extent;

(3) The heat recovery unit adopts heat collector technology, and the heat recovery capacity in summer can reach 30% to 40% of the cooling capacity, and the heat recovery capacity of the process chiller can reach up to 75% in winter.

3. Comprehensive Control Mode

(1) Screw water chiller adopts high-precision touch screen, advanced intelligent controller and computer control system, Chinese&English display, and connects with external equipment, remote users and control rooms by standard interfaces to realize the multiple control functions;

(2)Including compressor exhaust over-temperature, motor over-temperature, cold water anti-freezing and other multiple protection functions. Temperature protects over-current, phase loss, and reverse phase; Electrical protects refrigerant system high/low pressure, oil level, water cut off, etc.

(3)Above protection functions, maintenance and management functions such as alarms, reminders, records, and retrievals can be set;

(4) Automatic switch on and off, automatically realize unmanned operation management according to previously arranged work plan;

(5) Multiple password settings to ensure that the equipment will not be shut down and damaged due to accidental factors.

(6) Realize management functions such as remote data collection, operation inspection and control, and fault diagnosis through LAN or INTERNET.

Main Components

1. Compressor

(1) Imported high-efficiency economizer semi-hermetic twin-screw refrigeration compressor is adopted, which has a high energy efficiency ratio, reliable operation and long working life;

(2) Semi-closed design with only 3 moving parts, fewer parts and a low failure rate;

(3) Realize graded and step-less energy regulation, flexible and convenient control, energy saving, high efficiency and easy maintenance.

2. Condenser

The condenser is processed into trapezoidal low-assistance tubes to enhance heat transfer capacity. The copper pipe has a smooth surface, which reduces the water pressure and is easy to clean and maintain.

3. Evaporator

The dry-type in-tube evaporation evaporator is used, and the refrigerant evaporates and flows in the heat exchange tube. Adopts the latest CAD/CNC technology design, compact structure, and stable performance.

4. Automation Control System:

Developed PLC high-intelligence, computer control system, remote monitoring and controlling, easy operation. high safety, decreasing failure rate, and simple installation. The system control can be adjusted in real time, intuitive and reliable, The Chinese & English display screen, and menu-style buttons, can adjust the operating status of the unit, and it is a convenient operating env
