Overview

1. The high-efficiency energy-saving unit can be equipped with an independently patented heat recovery device. The heat recovery does not consume energy, and the overall efficiency of the unit can be increased by 5%, with an energy efficiency of up to 6.02. The unit has a single and double circuit design for reliable operation, meeting customer needs. Before leaving the factory, the unit undergoes safety testing to ensure that its performance meets enterprise standards. The intelligent control adopts microcomputer control, which can centrally manage system operations. Optional remote management program feedback system operation information to achieve remote service

Product Details

Product details configuration

Screw compressor+frequency conversion technology

Selecting Hanzhong brand semi enclosed twin-screw compressor, the compressor adopts cast iron shell, forged steel rotor, SKF bearings, which are efficient, energy-saving, durable, and have a long service life
By adopting onboard variable frequency drive technology and selecting Danfoss brand variable frequency drives, the energy efficiency of the chiller unit has been significantly improved under partial load conditions. The comprehensive partial load performance (IPLV) can reach around 10.0, and the energy-saving effect is significant

shell and-tube evaporator

The evaporator adopts a full liquid or falling film design, with refrigerant flowing through the shell side and water flowing through the tube side. The copper tube adopts 1.1mm thick copper heat exchange tube, ensuring that all products meet the high requirements of high efficiency, energy saving, safety, strong anti pollution ability, and durability

finned cooler

The fins are made of hydrophilic corrugated aluminum sheets, with a reasonable arrangement of copper pipes and a 'V' - shaped installation to improve heat transfer efficiency and reduce fan noise. Copper pipes and aluminum fins are tightly mechanically expanded, resulting in high performance and stable heat transfer. Adopting an external rotor axial flow fan, it has low noise, high airflow, high efficiency, and sufficient dynamic pressure

Heat recovery device

The condensation heat of the chiller unit (usually discharged into the atmosphere through the cooling tower) is recovered and effectively utilized. With the heat recovery cycle, the heat absorbed during refrigeration can be transported to the areas of the building that require hot water through heat recovery. During the cooling season, hot water above 50 ℃ can be provided for free

Human machine interface and control center

Adopting advanced and highly integrated PLC integrated controller, fully automatic operation, can be connected to Modbs upper computer system, 10 inch full-color human-machine interaction interface, simple operation, equipment operation data, fault display and solutions are clear at a glance, and can be connected to operation service system

IoT cloud service platform (remote control)

Equipped with advanced IoT cloud service platform, remote control can be achieved through mobile APP, real-time display of unit operation data, providing SMS pre alarm function, completely eliminating the need for on-site personnel duty, greatly reducing personnel costs
