150 Ton air cooled screw chiller system
Screw chiller system air cooled can be also called air cooled screw chiller, it's a type of air cooled chiller, the main component of the chiller is Semi-hermetic screw compressor. Oumal screw air chiller use the famous brand semi-hermetic screw compressor such as Hanbell from Taiwan or Bitzer from Germany.
The air-cooled screw chiller is named screw chiller because of its key component—the compressor adopts screw type. The state of the chiller from the evaporator is a gaseous refrigerant. After adiabatic compression by the compressor, it changes It becomes a state of high temperature and high pressure, in which the liquid refrigerant under low temperature and low pressure absorbs the heat of the refrigerating substance in the evaporator and becomes a gaseous refrigerant again. The gaseous refrigerant enters the compressor through the pipeline and starts a new cycle.
The air-cooled screw chiller is a screw chiller that can directly use the air condenser on the unit to dissipate heat into the air. It adopts the original imported twin-screw series compressor. The twin-screw 5:6 teeth number waits until the leading linear planning, energy saving High-efficiency, high-efficiency valve energy control, complete hierarchical or stepless energy control, balanced planning, super quiet and stable work.
Features of air-cooled screw chiller
1. The cooling capacity range is: 80kw to 800kw.
2. In addition to the general characteristics of the water-cooled screw chiller series in terms of assembly performance, the air-cooled screw chiller unit has the biggest advantage that it does not require a water cooling system, as long as it is well ventilated and can be used conveniently.
3. The air-cooled screw chiller does not need to be equipped with auxiliary equipment such as cooling water pumps, cooling towers, etc., which can save a lot of materials and engineering installation costs, and even do not need to set up a computer room.
4. Air-cooled screw chillers can be widely used in various industrial and civil building environmental air-conditioning systems such as hotels, restaurants, shopping malls, schools, hospitals, and offices.
5. In addition to finalized products, the company can also customize various special chillers and heat pump units according to customer requirements, and provide on-site assembly, technical guidance and on-site commissioning services.
6. The condenser of the air-cooled screw chiller is a fin type, adopts double-oil corrugated hydrophilic aluminum platinum, and is manufactured by professional heat exchanger processing equipment. It has the advantages of compact structure, small size, light weight and high heat exchange efficiency. , And equipped with a low-speed large-blade axial flow fan, which can effectively reduce operating noise and reduce the impact on the surrounding environment.
7. The control system of the air-cooled screw chiller unit adopts an imported PLC program controller, and the human-machine world is equipped with a large screen touch screen. The interface is simple and generous, and the operation is intuitive and simple.
8. The air-cooled screw chiller unit has reliable safety protection devices, including: high and low pressure protector, exhaust overheat protector, compressor motor overheat protector, overload current protector, water flow protector, emergency stop switch, sensor Temperature type fusible bolts, safety valves, etc.
Application range of screw air cooled chiller:
Screw air cooled chiller Mainly used in chemical plants, ink printing plants, automobile manufacturers or central air-conditioning systems or other large-scale industrial refrigeration.
