Screw Chiller Vs Scroll Chiller: Choosing The Right Cooling Solution

Screw chillers and scroll chillers are two common types of chillers. They are widely used in industrial and commercial fields, but they each have different characteristics and application solutions. What are the specific differences between the two? , how to choose, I believe this is a question that many people are paying attention to, so this article will share with you the differences between screw chillers and scroll chillers and answer your questions.

The compressor is one of the important core components of the chiller. The working principle of the screw chiller and the scroll chiller is to use the compressor to compress the coolant. The compressed coolant is transferred to the condenser and condensed through cooling. into a liquid state, and then enters the evaporator through the expansion valve, absorbs heat and converts the coolant into a gas state again, achieving the effect of cycle refrigeration;

The difference is that the screw chiller uses twin screw 5:6 tooth ratio refrigeration, while the scroll chiller uses rotating scroll compression refrigeration.

Since the screw chiller uses a twin-screw 5:6 gear ratio to work, it usually has a higher cooling capacity and can provide more efficient cooling capacity. It is suitable for large industrial scenes and high-load applications, and applications that have stricter temperature requirements. ; The scroll chiller has a smaller size but relatively lower cooling capacity, making it more suitable for small commercial scenarios and low-load applications.

There are many differences usage scenarios of screw chillers and scroll chillers; screw chillers are more suitable for large industrial projects, such as large industrial manufacturing plants, medical facilities, and commercial centers, especially in high-load and in a continuously running environment. Scroll chillers are more suitable for small commercial establishments such as hotels, office buildings and retail stores, as well as low-load applications such as small offices and catering establishments.

Since screw chillers are more suitable for large-scale industrial projects and high-load applications, requiring larger installation space; while scroll chillers are usually used in smaller commercial scenarios and low-load applications, so the external dimensions are also relatively small. No need to take up more space.

The design structure and control system of the screw chiller are usually more complex than the scroll chiller, requiring more frequent maintenance, more maintenance costs and debugging work, while the scroll chiller has a simpler structure, maintenance costs are lower.

Through the above comparison, I believe you should have guessed that the price of screw chillers is usually higher than that of scroll chillers. In addition to equipment performance and equipment structure, the prices of both will also be affected by other customized items and additional equipment. The impact of projects such as precise temperature control, intelligent control systems, energy efficiency optimization will also lead to an increase in the price of chillers.
