Gree industrial air conditioner LHE series high-efficiency chillers water screw water cooled chiller
Gree LHE series high-efficiency water-cooled screw chiller is a new generation high energy efficiency chiller,,use R134a green refrigerant,energy-efficient,reliable in operation,under nominal working conditions refrigeration capacity range :265-1400kw,Widely be used in various of office building,hospital,school,supermarket etc,also be used to cooling technogical process of products ,ice storage etc.
Features:
1.Adopt flooded evaporator,higher heat exchange efficiency
2.New throttle,more accurate control
3.optimization design,more reliable oil return system
4.High-efficiency and low noise oil separator,higher oil separate efficiency
5.Dual compressor dual circuit design,morereliable operation
6.Quick capacity adjustment,perfect load match up
7.Green and energy-saving,higher EER
Excellent mechanical characteristics
1.Special designed high-performance screw compressor for flooded chiller, higher compatibility, more efficient and stable in operation
*Patent high-efficiency rotor profile
Fully sealed between rotors,improve compressor efficiency and stability,increase rotor rigidity ,make compressor can adapt worse operation conditions,lower noise
*Revolutionary guiding valve design
Use VI guiding valve,make compressor load and unload more quick ,stable and reliable.
*Economy
Use increase enthalpy by replenish gas,make compressor larger exhaust ,improve unit performance, change inlet position of replenish gas,make compressor have higher energy efficiency.
2.Heat exchanger
*Evaporator
Use Gree independent research and development flooded evaporator, build-in particular refrigerant well-proportioned distribution device and gas liquid separation device,more uniform of refrigerant distribution,greatly improve heat transfer efficiency of evaporator,so improve units energy efficiency.
*Heat exchange tube
Use appropriative super efficient heat exchange tube and enhance heat transfer efficiency between water and refrigerant to improve unit energy efficiency.
Heat exchange tube connect tube plate by mechanical expansion to seal.at the position of expansion connect have 3 sealed grooves,greatly improve reliability of seal.
*Condenser
Preset prevent high-speed and high-pressure gas impact heat exchange tube device at the top of condenser,effectively contain vibration of heat exchange tube.greatly improve running stability of condenser.
Built-in subcooler at the bottom of condenser,improve subcooled temperature,improve refrigeration cycle efficiency of chiller.
*shell
The steel of evaporator shell and condenser shell use conform to China new pressure container standard.,ensure unit safety operation.
3.Water switch
Use famous brand pressure gradient water switch, greatly reduce fault of water switch.
4.perfect Damping
Unit deploy 8 piece of 50mm NBR shock pad,can completely meet unit shock absorption requirements.
5.Thermal insulation material
TOP quality thermal insulation material.the effect of insulation can guarantee unit no moisture condensation in any conditions.
6.excellent anticorrosive performance
Use TOP quality anticorrosive material and complex process, guarantee unit outstanding anticorrosive performance
7.Multiple protection function
Power default phase protection, Anti-phase protection, motor overload protection, motor overheating protection,anti-freeze protection,water flow switch protection,low flow protection,prevent constantly start protection,system high-Voltage protection,system low voltage protection,exhaust high temperature protection,high voltage low voltage difference protection,automatic anti-freeze protection,oil level switch protection,safety valve protection,sensor fault protection.
Other safety measures, such as hypertonus protection,pressure too low unload function,compressor oil heating controller function, minimum running time control function.ect.
