Skid mounted twin-screw chiller unit

Vortex chillers have been widely used in many fields due to their advantages of high efficiency, stability, and low noise. The following are their main advantages:

Efficient and energy-saving:

The compression process of a scroll compressor is continuous and smooth, without any clearance volume, and can achieve almost lossless compression, thereby improving the efficiency of the compressor. Compared with traditional piston compressors, the energy efficiency ratio (COP) of scroll compressors can usually be improved by 10% -30%. In addition, the vortex chiller unit can also be equipped with variable frequency drive technology to automatically adjust the compressor speed according to actual load requirements, so that the unit can maintain high energy efficiency even when operating at partial loads, further reducing energy consumption.

Stable and reliable operation:

The moving parts of a scroll compressor are few, with only one moving scroll and one stationary scroll moving relative to each other, and the movement speed is low, resulting in minimal vibration and impact. This enhances the stability of the unit during operation, reduces failures caused by component wear and vibration, and improves the reliability and service life of the equipment. At the same time, the refrigeration system of the vortex chiller unit is designed reasonably and has good resistance to liquid hammer, which can adapt to different operating conditions and work stably even at low or high loads.

Low noise:

Due to the fewer moving parts and smooth operation of scroll compressors, their operating noise is usually lower than other types of compressors. In general, the operating noise of vortex chillers is between 60-80 decibels. Compared with piston or screw chillers, the noise level is significantly reduced, providing users with a quieter working and living environment. It is particularly suitable for places with high noise requirements, such as hospitals, hotels, office buildings, etc.

Compact structure:

The structure of the scroll compressor is simple, small in size, and light in weight, making the overall structure of the scroll chiller relatively compact. Under the same cooling capacity, the footprint of a vortex chiller is usually 20% -30% smaller than that of a screw chiller, which can effectively save room space, facilitate installation and layout, and is particularly suitable for use in places with limited space.

Accurate temperature control:

The vortex chiller unit adopts an advanced control system, which can accurately control the cooling capacity and water temperature. By adjusting the speed of the compressor and the flow rate of the refrigerant, precise control of the chilled water temperature can be achieved. The temperature control accuracy can generally reach ± 0.5 ℃, meeting various processes and application scenarios with high temperature requirements, such as electronic equipment cooling, precision instrument manufacturing, etc.

Good partial load performance:

In practical operation, the cooling load demand in many places varies over time, and vortex chillers perform well under partial load conditions. Variable frequency vortex chillers can accurately adjust the output power of the compressor according to changes in load, enabling the unit to maintain high efficiency even at low loads, avoiding the problem of energy efficiency reduction in traditional fixed frequency units at partial loads, and thus reducing the annual operating costs.
