Water-cooled screw chillers are widely used in industrial refrigeration projects of different scales in various industries, such as factory environment, factory equipment cooling, chemical industry, aquaculture, reaction kettle, fermentor, hospital, refrigeration and so on. KDS screw chiller is a chiller that our company is committed to research, design and development with many years of experience in designing and producing chillers and the latest scientific and technological development. This product conforms to the development trend of the times and adheres to the design concept of "high efficiency, reliability, energy saving and environmental protection" to provide users with an excellent refrigeration equipment.
2. Features
Water-cooled screw chiller adopts screw compressor of international famous brand, and is equipped with high-quality and high-performance copper tube to make condenser, evaporator and world-famous control elements, which makes the chiller have the advantages of small volume, low noise, large energy, long service life and simple operation. Its exquisite and delicate design and reliable and stable high-performance quality stand out among similar products!
Compressor characteristics:
The compressor adopts international brand, a new type of high-efficiency spiral rotor compressor, which is 20%-30% higher than the general compressor, and has obtained European and American patents and international quality certification of ISO900 1.
Efficient control of 5: 6 patent asymmetric rotor tooth profile.
Capacity control can adopt four-level (100%-75%-50%-25%) or three-level (100-66%-33%) and stepless control system.
Adopt high-efficiency silicon steel and special groove design, equipped with internal and external omni-directional cooling channels, so that the compressor motor can play the highest efficiency under any load.
Unique built-in oil pressure system ensures that the compressor maintains the best lubrication effect without oil pump.
The oil separator adopts double-layer filtration mode, which has good oil filtering effect and the heat exchanger can exert its maximum capacity.
High efficiency, low noise and low vibration.
The system has the functions of motor overload, short circuit protection, overheating, high and low pressure, compressor delayed start protection, water flow protection and so on, and the unit runs safely and reliably.
3. Working principle
The main components of the device are: compressor, condenser, drying filter, gas-liquid separator, expansion valve, evaporator, control instrument and control element.
The working principle is as follows:
Refrigeration principle: When the refrigeration system works, the high-temperature and high-pressure refrigerant gas discharged by the compressor enters the condenser and condenses into medium-temperature supercooled liquid, which is throttled and depressurized by the low-temperature expansion valve to become a low-temperature and low-pressure vapor-liquid two-phase mixture, which enters the evaporator and evaporates in the evaporator to absorb the heat of the refrigerant flowing through the evaporator, so that the refrigerant flowing through the evaporator is cooled, and the vapor after evaporation of the refrigerant is sucked by the compressor and continuously circulated, thus achieving the purpose of cooling down.
