The compressor unit is the main equipment of the freezing processing and cold chain industry. It consists of the compressor, pressure vessel, refrigeration element, electrical control, and various valve parts.
The main components of compressor units cooperate with domestic and abroad well-known brands, according to user configuration to type compressor units and engineering demand, in the form are single and double screw parallel units, double screw parallel units, inverter screw units, piston compressor, and refrigerant special refrigeration unit.
Basic Configuration of the Refrigeration Unit
To deliver stable and high-performance cooling, our refrigeration unit integrates key components that are carefully selected for reliability and efficiency. The following are the standard configurations:
Compressor
At the heart of the refrigeration unit, we incorporate compressors from internationally renowned brands such as Bitzer, RefComp, and Frascold. These compressors are known for their superior quality, safety, and long-term reliability. Furthermore, we offer customized power supply options to suit specific operating environments.
High-Efficiency Oil Separator
To ensure continuous and efficient operation, the refrigeration unit is equipped with a high-efficiency oil separator. This component effectively removes refrigerant oil from the circulation loop and simultaneously delivers it back to the compressor, maintaining lubrication and system balance.
Reservoir
As part of the standard design, the reservoir meets conventional specifications. However, we can flexibly increase its volume based on your project’s cooling load and application needs, ensuring the refrigeration unit adapts perfectly to on-site conditions.
Gas-Liquid Separator
In contrast to basic systems, our refrigeration units include gas-liquid separators with integrated heat exchange functionality. This design is especially beneficial for low-temperature refrigeration or systems without an independent heat exchanger, enabling more efficient phase separation and thermal performance.
Filter
For easy maintenance and long-term durability, the unit comes with a detachable filter barrel. This allows quick access and hassle-free replacement of filter elements, minimizing downtime during servicing.
Solenoid Valve
To enhance control and operational flexibility, we install high-quality Danfoss solenoid valves. These can be mounted directly on the refrigeration unit or externally along the cold storage pipeline, depending on installation preferences.
Expansion Valve
Lastly, the refrigeration unit features an electronic expansion valve, which outperforms traditional mechanical valves. With a wider adjustment range and more precise flow control, it greatly enhances energy efficiency and temperature regulation throughout the system.
Air-Cooled Condenser
An air-cooled condenser is a type of heat-dissipating equipment, available in four models: H, V, U, and L. The H and L types feature side blowing, while the V and U types are designed for roof blowing.
Key Features:
Versatile and Compatible: Thanks to its reasonable structure, the unit is compatible with various compressor models.
Durable Construction: The shell is constructed from high-quality steel plates, providing excellent corrosion resistance and a sleek appearance.
Reliable Performance: Each unit undergoes a 2.5MPa air-tightness test to ensure consistent performance and dependability.
Refrigerant Flexibility: Compatible with multiple refrigerants, including R22, R134a, and R407c.
Customizable Options: Depending on specific customer needs, different types of condensing fans can be selected to optimize system performance.
Evaporative Condenser
The evaporative condenser is a high-efficiency, energy-saving heat exchange solution. It works by spraying water onto the surface of heat exchange coils, forming a water film that evaporates and absorbs heat from the fluid inside the coils—thereby condensing the refrigerant more effectively.
Key Features:
Enhanced Energy Efficiency: By directly discharging the refrigerant’s heat to the air and water, the condensation temperature is reduced by approximately 4°C compared to traditional water-cooled systems. This improves energy efficiency by up to 12%, eliminates the need for a cooling water pump, and significantly lowers power consumption.
Optimized Water Distribution: The cooling water spray system uses high-flow, anti-blocking basket-type nozzles. These ensure continuous, even water distribution and maximize heat exchange between water, air, and refrigerant.
Superior Heat Exchange Technology: The system utilizes same-direction mixed-flow coil technology combined with PVC filler to achieve high-efficiency heat transfer.
