Recirculating Water Chiller
Core technology
Through four core technologies - real-time flow control, efficient falling film evaporation, efficient oil separation and return technology, and Internet of Things remote intelligent services - the unit's energy efficiency has been increased by 10%, and its operation and maintenance are worry-free and cost-effective. The unit is more efficient, reliable and stable. The remote intelligent service center can monitor in real time and handle faults quickly online, providing customers with a more considerate and prompt product experience and after-sales service.
Save energy efficiency
The national patented falling film evaporation technology uses high-efficiency falling film heat exchange tubes. The refrigerant is evenly drizzled onto the heat exchange tube array through the liquid distributor and forms a film on the surface of the heat exchange tubes, allowing the refrigerant to fully contact the heat exchange tubes. The heat exchange efficiency is increased by more than 10% compared with the traditional flooded evaporator, the refrigerant charge is reduced by 27%, and the oil return effect is improved. It can effectively reduce the volume of the unit by more than 20%, providing a larger space for the layout of the machine room. This technology has been successfully patented: Falling film Evaporator for Refrigeration and Air Conditioning, patent number: ZL201520313780.5
Stable and reliable
The GRAD national patent external high-efficiency oil separation technology, through the high-efficiency external secondary oil separator composed of the shell, end head, intake pipe assembly, baffle, oil and gas filter screen assembly, outlet assembly, return oil port and sight glass, adopts the three-stage separation principle of oil and gas collision deflection separation, gravity sedimentation separation and filtration separation to separate the refrigerant gas and the lubricating oil in the gas Its structure is simple, easy to manufacture, with high separation efficiency, stable and reliable operation of the unit, and no risk of liquid carrying in the suction.
