What are the Characteristics of Screw Chiller?

Feb. 24, 2020

With the development of the industrial economy, the use of chillers is becoming more and more widespread, and more and more people and industries are exposed to chillers. When we buy chiller, we often hear the term screw chiller. Its screw chiller is a type of chiller, which is commonly known as Air Cooled Screw Chiller because of its use of screw compressors. Because its cooling power is greater than the power of the scroll chiller, so some chemical plants, automobile manufacturers, ink printing plants will choose screw chiller for use.

So do you know what are the characteristics of screw chiller? The Water Cooled Screw Chiller Factory will tell you below.

Features of screw chiller:


1. The evaporator and condenser of the screw chiller have been integrated into a whole, which no longer takes up additional space. In addition, the unit is simple and does not require a large maintenance space, so the area of the machine room can be greatly reduced.


2. Since the vibration of the screw type industrial chiller is very small, the foundation is simple. The machine room can be located close to the place where cooling is required, or it can be placed on each floor. Especially in high-rise building air-conditioning systems, the pump lift can be greatly reduced, reducing installation and operating costs.


3. The screw-type chiller is installed once during the installation of the whole unit, and 100% test machine test is performed before leaving the factory. Therefore, it is easy to connect water and electricity, reducing the installation and commissioning workload, and simple and safe operation. Compared with piston chiller, it has flexible adjustment, simple structure, less wearing parts, no suction, exhaust valve, insensitive to wet stroke, and extremely low failure rate.


4. The screw chiller uses multiple refrigeration circuits. Two compressors or multiple compressors have a cycle control program for starting and stopping, which can balance the load and prolong the service life of the unit. If one of the circuits requires maintenance, the remaining circuits It can still operate normally and has a backup function.


5. Screw-type chiller can be equipped with environmental protection and energy saving heat energy recovery device according to needs, which can produce free hot water during refrigeration. Simple installation without cooling water tower. It can also perform intelligent program control according to load changes: 100%, 75%, 50%, 25% capacity adjustment, saving energy consumption.


6. Generally, when the heat pump unit is running, the pressure in the working condition will be relatively large. At this time, it is more suitable to use the screw chiller. Due to the low steam temperature of the screw-type consumables, the condenser fouling situation is much lower than that of the piston chiller, which helps maintain high heat transfer efficiency and operating stability.


The above are the characteristics of the screw chiller introduced by Air Cooled Chiller Manufacturer. Hope to help you.
