Air cooled screw industrial integrated chiller unitProduct Introduction

LJR-WSeries air-cooled screw industrialchillerIt is the foundation of Guangzhou Lingjing Refrigeration Equipment Co., Ltd. in various aspects of absorption screw chillers5：6The rotor twin-screw compressor serves as the refrigeration core, equipped with a condenser and evaporator, using electrical components, and supplemented withPLCComputer control system, assembled through processing technology

1.The air-cooled condenser is a fin type, using double oil ripple hydrophilic aluminum platinum, manufactured by heat exchanger processing equipment,And equipped with low-speed large blade axial flow fans, it can reduce operating noise and minimize the impact on the surrounding areaThe impact of the environment.

2.The unit control system adoptsPLCThe program controller is equipped with a large touch screen in the human-machine interface, with a simple and elegant interface and intuitive operation.

3.The unit is equipped with reliable protective devices, including high and low voltage protectors, exhaust overheat protectors, compressor motor overheat protectors, overload current protectors, antifreeze temperature protectors, water flow protectors, emergency stop switches, temperature sensitive melting plugs, safety valves, etc.

Air cooled screw industrial integrated chiller unitmodel selectionparameter

LJR-AThe series of chillers are air-cooled single cooling series, and the cooling capacity range of a single unit is101KWto860KWThe temperature adjustment range of chilled water is5℃ to20℃. Users can also customize units with lower outlet temperatures according to their needs. The unit implements automatic intelligent operation control,. The advantage of this type of unit is that it does not require a dedicated computer room or water cooling system, and can be installed and placed outdoors in a well ventilated area with minimal material and engineering installation costs.（due toModel of air-cooled screw industrial integrated chiller unitCould not provide a detailed list.

Air cooled screw industrial integrated chiller unitWorking principle

The high-pressure and high-temperature gas from the compressor enters the finned condenser, and the heat is dissipated by the fan into the outside air to become high-pressure and room temperature liquid. The high-pressure and room temperature liquid enters the expansion valve throttling mechanism for pressure reduction, and some of the liquid flashes into vapor. These low-temperature and low-pressure gas-liquid two-phase mixtures enter the evaporator, where they exchange heat and cool with the high-temperature hot water of the customer's industrial equipment. Then, the medium in the evaporator becomes vapor and returns to the compressor for re compression, completing a cycle. The chiller unit continuously exchanges heat and cools down the mechanical equipment and products supplied to customers
