Falling film screw chiller unit

FALLING FILM SCREW CHILLERS

Brief Introduction of the Unit

The LJR series falling film screw chiller is an energy-saving product with high energy efficiency ratio independently developed, designed, and manufactured by Guangzhou Lingjing Refrigeration Equipment Co., Ltd,

We use the internationally renowned screw compressor "Hanzhong" and electronic control components for processing and manufacturing, equipped with efficient and high-quality shell and tube condensers and falling film evaporators.

The LJR series of falling film screw chillers have a total of forty specifications, with a cooling range from 500kW to 3600kW and a chilled water outlet temperature adjustment range of 5 ℃ to 20 ℃

The group is suitable for industries such as hotels, shopping malls, office buildings, food, solar photovoltaics, pharmaceuticals, etc.

Features of the Unit

Features of the unit

1. Efficient and energy-saving

Having the production capacity of major components, independent intellectual property rights, perfect system matching, and a total energy efficiency of 5.2 or above, the energy consumption of the whole machine is reduced compared to similar dry type products

15%-25%;

Adopting a screw compressor with stable performance, low noise, and long motor service life;

·Adopting independently developed high-efficiency falling film shell and tube heat exchangers with compact structure and strong heat transfer capacity;

·Adopting evaporator injection oil return technology;

Efficient oil separator using impact and interception oil separation technology;

·The unit can be equipped with a heat recovery device, which can recover 30% to 80% of the cooling capacity when the air conditioner is in use. The maximum temperature of the hot water outlet can reach 70 ℃

·During heat recovery, the overall efficiency of the unit can be improved by 10%

2. Reliable operation

·The unit is equipped with protection devices such as phase loss protection, motor overload protection, high and low voltage protection, low temperature protection, and water flow protection.

·The unit is equipped with single and double circuit designs to meet customers' different choices. When a single compressor in the double circuit unit configuration fails, the other compressor can still function

Normal operation without affecting customer usage.

·All units undergo a 100% safety testing system before leaving the factory to ensure that their performance meets national standards.

3. Intelligent control

·The unit is controlled by a microcomputer and can be operated through a centralized management system. The unit can also be equipped with a remote management program to provide feedback on system operation information and achieve remote services.

4. Easy installation and maintenance

The unit has been filled with refrigerant and lubricating oil before leaving the factory, and customers only need to connect the inlet and outlet pipes and power supply to operate,

·The control interface directly displays the fault content, which facilitates timely understanding and troubleshooting of the fault.

5. Special Design

·The unit can flexibly design the external dimensions according to the conditions of the computer room, and can be shipped in pieces and assembled on site,

·Multiple refrigerant options, the unit can provide refrigerant media such as R22, R134a, etc

Produce units with different power supply standards according to the power supply of different countries and regions, and also customize various high-voltage non-standard units according to user requirements.
