The refrigeration cycle is characterized by the ability to extract heat from an object that is at a lower temperature than the surrounding environment and transfer it to the ambient medium. This process is typically accomplished using a screw chiller, with the refrigeration compressor being the most critical component of the system. Understanding the working principle of the screw chiller’s refrigeration compressor is essential for grasping how this technology functions efficiently in various industrial applications.
Dongyuejin brand screw chillers are widely used in large-scale environments such as printing factories, chemical plants, battery manufacturing facilities, food preservation centers, and central air conditioning systems. These chillers are designed to provide high cooling capacity and energy efficiency, making them ideal for demanding applications where consistent temperature control is crucial.
A typical single-stage screw chiller consists of four main components: the screw refrigeration compressor, the condenser, the expansion valve, and the evaporator. These parts are interconnected through piping to form a closed-loop refrigeration system. In addition to these core components, the system also includes an oil circuit system, which plays a vital role in lubricating, cooling, and sealing the internal mechanisms of the compressor.
The oil circuit system of the Dongyuejin screw chiller includes elements such as an oil separator, oil cooler, oil pump, oil filter, and pressure regulating valve. These components work together to ensure that the lubricating oil is properly cooled, filtered, and distributed throughout the system. The amount of oil injected into the compressor is approximately 0.5% to 1% of the compressor’s theoretical displacement, ensuring smooth operation and reducing mechanical wear.
The working principle of the screw chiller refrigeration compressor is similar to that of a piston-type compressor but operates more efficiently due to its continuous compression process. Inside the compressor housing, two interlocking rotors (a male rotor and a female rotor) rotate within a figure-eight-shaped chamber. As the rotors turn, their teeth mesh together, gradually reducing the volume of the gas pockets. This reduction in volume increases the pressure of the refrigerant, allowing it to be effectively compressed and circulated through the system.
In addition to its mechanical function, the screw chiller is equipped with a control system that allows for precise temperature regulation. When the desired temperature is reached, the compressor automatically stops, and when the temperature rises above the set point, it restarts on its own. This intelligent control mechanism helps save energy and reduce electricity consumption, making the system both efficient and cost-effective.
Overall, the Dongyuejin brand screw chiller represents a reliable and advanced solution for industrial cooling needs. Its robust design, efficient operation, and smart control features make it a preferred choice in a wide range of applications. Whether for large-scale production or commercial HVAC systems, the screw chiller continues to play a key role in modern refrigeration technology.
