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
Shell and tube condenser
Shell and tube condenser is a high-efficiency heat exchanger that exceeds the standard. Different materials of heat exchange tubes can be selected according to customer usage conditions and water quality factors. It can also increase the fouling coefficient to enhance heat exchange efficiency, ensuring high efficiency, energy saving, and service life of the unit
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
